⚠️ What to watch

😰Extreme heat risk increases from the Central/Southern Plains to the Lower Mississippi Valley and Southeast around Aug 14–16
⚠️Heat and limited rain may cause drought to develop quickly in the Central/Southern Plains and Lower Mississippi Valley
☁️Monsoon downpours may hit the Southwest, Great Basin and Rockies around mid-August, while the Southern Plains trend drier
πŸ”₯Above-normal wildfire potential across the Northwest and interior West, plus renewed risk in the Southern Plains
πŸŒ€Atlantic hurricane activity should be quieter than usual, but peaks August–October β€” Gulf/East Coast impacts still possible

What's going on with temperature

Warmer than usual across most of the West, Central/Southern Plains, and much of the South and Southeast

Monthly Temperature Outlook map
  • The strongest warm signals are over the Southern Plains and coastal California
  • The Northern Plains, Great Lakes and Northeast are harder to predict, with bigger day-to-day swings
  • Alaska leans warmer in the far eastern Mainland and Southeast; Hawaii is warmer than usual too

What's going on with precipitation

Wetter across the Southwest and Great Basin β€” drier in the Southern Plains and Pacific Northwest coast

Monthly Precipitation Outlook map
  • Monsoon moisture moving north could bring wetter periods as far as the Rockies
  • Drier conditions are favored across the Southern Plains and the Washington/Oregon coasts
  • Most of the eastern U.S. has no clear signal, though parts of the Northeast lean wetter
  • Alaska leans wetter in the west and north, drier in the southeast; Hawaii leans wetter too, especially Maui and the Big Island
πŸ€” Why this is happening
β€ΊA large area of high pressure aloft favors long warm stretches across the West and South
β€ΊA southward dip in the jet stream can bring cooler, unsettled weather from Canada into the Northern Plains and Great Lakes β€” shifting toward the Northeast by mid-August
β€ΊMonsoon moisture moving north from Mexico fuels storm chances across the interior West
⚠️A moderate El NiΓ±o supports the hotter, drier lean in the Southern Plains and points to a quieter Atlantic hurricane season β€” though hurricanes remain possible, since activity typically picks up in August

Pacific Coast

WA, OR, CA

Pacific Coast map

β˜€οΈ Warm, with little rain relief in the Northwest

  • A warmer-than-usual August is favored, with the strongest confidence along the California coast
  • Coastal Washington and Oregon lean drier; California has no strong wet-or-dry signal for the month
  • Drought may persist or slowly expand across the Northwest
  • Wildfire potential is above normal across the Northwest, extending into northern California
πŸ€” Why this is happening
β€ΊHigh pressure aloft favors long warm stretches here, while monsoon moisture stays mostly to the south and east β€” offering little rain relief
See the latest forecast

Interior West & Southwest

ID, NV, UT, AZ, NM, CO

Interior West and Southwest map

β˜” More monsoon moisture, but uneven rainfall

  • Wetter-than-usual conditions are favored, with wetter periods possible reaching into the Rockies
  • Temperatures still lean warmer overall, though clouds and storms may interrupt the heat
  • Monsoon rain may gradually ease drought in Arizona, far western New Mexico and the Great Basin β€” but improvement will be uneven
πŸ€” Why this is happening
β€ΊMonsoon moisture from Mexico spreads into this region, increasing storm chances even as the broader pattern stays warm
See the latest forecast

Northern Rockies & Plains

MT, WY, ND, SD, NE

Northern Rockies and Plains map

🌑️ Warm spells interrupted by Canadian air

  • The temperature outlook is more changeable here than farther south, especially in the Dakotas and Nebraska
  • Cooler Canadian air can bring short-lived breaks between warmer stretches
  • Drought may persist or expand in parts of North Dakota and western South Dakota despite occasional storms
πŸ€” Why this is happening
β€ΊThis region sits closer to the path of dips in the jet stream, so cooler air from Canada interrupts the broader warm pattern more often than farther south
See the latest forecast

Midwest & Great Lakes

MN, IA, MO, WI, IL, IN, MI, OH

Midwest and Great Lakes map

β›ˆοΈ Alternating stormy and quieter periods

  • The northern Midwest and Great Lakes may swing between warm spells and cooler periods; southern parts lean warmer
  • Storms are more likely earlier in the month; by mid-August, the cooler, stormier pattern shifts toward the Northeast
  • Parts of Minnesota, Wisconsin and western Iowa that miss the heavier storms could see drought develop or worsen
πŸ€” Why this is happening
β€ΊThis region sits in the path of the jet stream's southward dips, so it swings between warm ridges and cooler, stormier breaks more than areas farther south
See the latest forecast

Central & Southern Plains / Lower Mississippi Valley

KS, OK, TX, AR, LA

Central and Southern Plains map

πŸ”₯ The main heat zone

  • This region has one of the country's strongest signals for a hotter-than-usual August
  • Drier-than-usual conditions are favored, though occasional storms may interrupt the heat
  • NOAA highlights a mid-August extreme heat risk, with the possibility of drought developing quickly
πŸ€” Why this is happening
β€ΊA moderate El NiΓ±o and high pressure aloft combine here, favoring persistent heat and limiting rain more than almost anywhere else in the country
See the latest forecast

Southeast

MS, AL, TN, KY, GA, FL, SC, NC

Southeast map

☁️ Hot, with highly variable rainfall

  • Warmer-than-usual temperatures are favored
  • There's no clear wet-or-dry signal for the month as a whole β€” it depends on which weather systems pass through
  • A wetter start to August should help existing drought gradually ease
  • Extreme heat may become a concern around mid-month, with tropical moisture as a wildcard
πŸ€” Why this is happening
β€ΊThe Southeast sits between the drier Plains ridge and the more active tropics, so rainfall depends heavily on which pattern wins out week to week
See the latest forecast

Northeast & Mid-Atlantic

WV, VA, MD, DE, PA, NJ, NY, CT, RI, MA, VT, NH, ME, DC

Northeast and Mid-Atlantic map

🌧️ More changeable, with better rain chances

  • Around mid-August, the jet stream may dip south, bringing cooler Canadian air and more weather systems into the region
  • Parts of the Northeast lean wetter, and more frequent rain should gradually ease drought β€” recovery may be slower in parts of the Mid-Atlantic where groundwater remains low
  • This doesn't mean constant rain or a cool month overall β€” just a more changeable pattern than farther south
πŸ€” Why this is happening
β€ΊThis is the region most likely to feel the mid-month shift in the jet stream, bringing more variety in temperature and rain than the persistent heat farther south
See the latest forecast

Alaska

AK

Alaska map

β˜” Wetter in the west and north

  • Low pressure may bring unsettled weather to central Alaska early in August, shifting toward western Alaska by mid-month
  • Western and northern Mainland Alaska lean wetter, while Southeast Alaska leans drier
  • The temperature outlook is mixed, with the clearest warm signal in the far eastern Mainland and Southeast
πŸ€” Why this is happening
β€ΊAlaska sits mostly outside the ridge pattern driving heat farther south β€” a drifting area of low pressure is what's steering this month's wetter weather toward the west and north
See the latest forecast

Hawaii

HI

Hawaii map

🌺 Warmer and wetter than usual

  • Above-normal temperatures are favored across all the islands
  • August also leans wetter, with above-normal rainfall favored overall
  • This is about total rainfall over the month, not rain every day β€” no drought development is expected
πŸ€” Why this is happening
β€ΊWarmer-than-usual surrounding ocean waters are the main driver for August's warmth β€” but unlike the drier pattern El NiΓ±o typically brings to Hawaii, this month's wetter lean looks more tied to near-term tropical moisture than to the broader seasonal signal

September 2026

US Expert Weather Outlook

What our meteorologists expect this month β€” and what it means for your outdoor plans.

Choose your region:

⚠️ What to watch

😰Extreme heat risk is highest across the central and southern Plains through the first ten days of September
⚠️Heat and limited rain may let drought develop quickly from Texas and Oklahoma through Kansas and Missouri around Sep 10–16
☁️Rain chances stay elevated across the Southwest and along the Pacific Coast, while the central Plains trend drier
πŸ”₯Wildfire potential is above normal across the Northwest, parts of the Interior West, the southern Plains and Lower Mississippi Valley, plus South Florida
πŸŒ€Atlantic hurricane season peaks around Sep 10, though NOAA's updated outlook still favors a quieter-than-usual season

What's going on with temperature

Warmer than usual across the central Plains, the South, and much of the West β€” with a pocket of cooler air in the Pacific Northwest

Monthly Temperature Outlook map
  • The strongest warm signal is centered over Kansas, Oklahoma, Nebraska and Missouri, where dry ground is helping the heat build quickly
  • The Northeast is harder to predict this month, with close to even odds of ending up warmer, near normal, or cooler
  • Alaska leans warmer in the southeast and cooler in the west and north; Hawaii is warmer than usual too

What's going on with precipitation

Wetter than usual across the West and along the Pacific Coast β€” drier across the central Plains

Monthly Precipitation Outlook map
  • California, the Rockies and the Southwest should see more rain than usual, with the best chances along the Oregon coast
  • The central Plains and central Mississippi Valley trend drier, especially in the first ten days of the month
  • Southeast Texas could get an extra soaking from tropical moisture moving in off the Gulf, and the same moisture helps South Florida
  • Alaska leans wetter across most of the state; Hawaii leans wetter too
πŸ€” Why this is happening
β€ΊA dip in the jet stream moves through the West early in the month, while high pressure aloft builds and holds over the central Plains for much of the first ten days β€” that combination is driving both the heat and the dryness there
β€ΊMonsoon moisture moving north from Mexico keeps rain chances up across the Southwest and the Great Basin, while a separate dip in the jet stream brings rain to the Pacific Coast
β€ΊThe Northeast sits between these patterns, which is why its temperature outlook is harder to call than the rest of the country
⚠️A strong El NiΓ±o β€” still strengthening, with some chance it becomes one of the strongest on record this winter β€” supports the hotter, drier lean in the Plains and points to a quieter Atlantic hurricane season overall, though the season is near its historical peak, so Gulf and East Coast impacts remain possible

Details by region

Scroll down or tap a region in the menu above.

Pacific Coast

WA, OR, CA

Pacific Coast map

🌊 Cooler start, with rain returning

  • A dip in the jet stream keeps the region cooler, cloudier and more unsettled than usual for the first part of the month
  • Rain runs above normal for the whole coast, with the best chances in Oregon
  • A narrow strip right along the coast stays cooler than usual too
  • Wildfire potential stays above normal across most of the Northwest and far northern California, though the coast itself gets a break from the wetter start to the month
πŸ€” Why this is happening
β€ΊA passing dip in the jet stream is bringing both the rain and the cooler temperatures to the coast this month
See the latest forecast

Interior West & Southwest

ID, NV, UT, AZ, NM, CO

Interior West and Southwest map

β˜” Wetter, with the monsoon still running

  • Rain stays above normal across the region as monsoon moisture keeps arriving from Mexico
  • Temperatures lean warmer overall for the month
  • Wildfire potential is still above normal in central and southern Idaho, northern Nevada and northern Utah
πŸ€” Why this is happening
β€ΊMonsoon moisture moving north keeps storm chances elevated here even as the broader pattern stays warm
See the latest forecast

Northern Rockies & Plains

MT, WY, ND, SD, NE

Northern Rockies and Plains map

🌾 About an average month

  • Neither temperature nor rainfall shows a strong lean here this month
  • Existing drought is expected to stick around, with little relief in sight
πŸ€” Why this is happening
β€ΊThis region sits between the high-pressure dome parked over the Plains to the south and the dip in the jet stream moving through the West, so neither pattern takes over here this month
See the latest forecast

Midwest & Great Lakes

MN, IA, MO, WI, IL, IN, MI, OH

Midwest and Great Lakes map

🌀️ Warmer in the south, wetter in the east

  • The warm lean is strongest in the southwest of the region, closer to the heat over the Plains
  • The eastern Great Lakes trend wetter than usual, which should help lake levels heading into fall
  • Wildfire potential is above normal in northern Minnesota, northern Wisconsin and the western Upper Peninsula of Michigan
πŸ€” Why this is happening
β€ΊThis part of the region sits closer to the high-pressure dome driving heat over the Plains, while the eastern Great Lakes catch more of a wetter pattern moving in from the south
See the latest forecast

Central & Southern Plains / Lower Mississippi Valley

KS, OK, TX, AR, LA

Central and Southern Plains map

πŸ”₯ The hottest, driest spot on the map

  • This region has the strongest signal for a hotter-than-usual September, especially in the first ten days
  • Rain trends below normal here too, as the same high pressure limiting clouds also limits storms
  • The exception is southeast Texas, which could see a heavy soaking from tropical moisture moving in off the Gulf
  • Fast-developing drought is a real risk here around Sep 10–16
  • Wildfire potential is above normal across the southern Plains and the Lower Mississippi Valley too
πŸ€” Why this is happening
β€ΊHigh pressure aloft parks over this region for much of the first third of the month, and ground that's already dry lets the heat build even faster
See the latest forecast

Southeast

MS, AL, TN, KY, GA, FL, SC, NC

Southeast map

β˜€οΈ Warm all month

  • Warmer-than-usual temperatures are favored across the region
  • South Florida picks up some extra rain from tropical moisture, though wildfire potential there is still running above normal
  • Eastern North Carolina trends drier than usual, a small exception in an otherwise wetter East Coast pattern
πŸ€” Why this is happening
β€ΊThe Southeast sits under the same high pressure driving heat over the Plains, which keeps the whole region warm; tropical moisture pushing in locally, like the extra rain reaching South Florida, is a separate factor on top of that
See the latest forecast

Northeast & Mid-Atlantic

WV, VA, MD, DE, PA, NJ, NY, CT, RI, MA, VT, NH, ME, DC

Northeast and Mid-Atlantic map

🌦️ Hard to call, but leaning wetter

  • Temperature could go either way this month β€” warmer, near normal, and cooler are all close to equally likely
  • Rain trends wetter for most of the region, though a narrow strip along the coast trends slightly drier
πŸ€” Why this is happening
β€ΊThis region sits right where a possible dip in the jet stream and higher rain odds pull the forecast in different directions, which is why temperature is harder to call here than farther south
See the latest forecast

Alaska

AK

Alaska map

❄️ Mild southeast, cooler north and west

  • The southeast, including the Panhandle, runs mild this month
  • The west and north lean cooler than usual
  • Rain trends above normal across most of the state
πŸ€” Why this is happening
β€ΊA dip in the jet stream forecast near western and northern Alaska is what's driving the cooler lean there; the Panhandle sits outside that influence and stays milder
See the latest forecast

Hawaii

HI

Hawaii map

🌺 Warm and wet, the most confident call on the map

  • Above-normal temperatures are favored across all the islands, and it's one of the most confident calls in this month's outlook
  • Rain also leans above normal for the month
πŸ€” Why this is happening
β€ΊSeptember falls in Hawaii's dry season (May through September), when El NiΓ±o tends to bring wetter conditions β€” the reverse of its usual drying effect once the wet season starts in October
β€ΊThis same El NiΓ±o is driving an above-normal Central Pacific hurricane season, and passing tropical systems are a major source of summer rain for the islands
