7-Day Outlook: August 19–25, 2026
Areas of fog this morning will give way to mostly cloudy skies today, with temperatures reaching the upper 70s. Winds will be light, becoming southwest at around 5 to 10 mph this afternoon. Scattered showers and isolated thunderstorms are expected to develop this afternoon, with the greatest potential across northern areas. A few thunderstorms could produce brief heavy rain and gusty winds, but widespread severe weather is not expected. The chance of precipitation will be around 30 percent.
Scattered showers and thunderstorms will continue into this evening before becoming isolated by late evening. Patchy fog will develop overnight as skies remain mostly cloudy. Temperatures will fall into the mid-50s, with light southwest winds. Most locations will receive little rainfall, and many areas will remain dry.
Thursday will be mostly sunny overall, although a few isolated showers and thunderstorms may develop during the afternoon as the weakening front approaches the region. Temperatures will reach the lower to middle 70s, with light northwest winds around 5 mph. The chance of precipitation will be around 20 percent, and most locations will not receive measurable rainfall.
The front will move through Thursday night, followed by clearing skies and the arrival of higher pressure from the west. Areas of fog may develop late Thursday night, with temperatures falling into the upper 40s and winds becoming calm.
Friday will bring a return to dry and mostly sunny weather. Areas of morning fog will dissipate by mid-morning, followed by a pleasant afternoon with temperatures in the lower 70s. Winds will be light early, becoming northwest at around 5 to 10 mph during the afternoon. Mostly clear skies will continue Friday night, although patchy fog may develop toward morning. Overnight temperatures will fall into the middle 40s.
A low pressure system will approach from the Great Lakes on Sunday and move into Quebec by Monday, while another area of low pressure tracks along the coast and brings additional moisture into the region. Increasing clouds and a few showers are expected Sunday, with a chance for thunderstorms during the afternoon. Temperatures will reach the lower to middle 70s, with a 50 percent chance of precipitation.
Showers will become more likely Sunday night and continue into Monday as the low pressure system moves through. A few thunderstorms will also be possible, particularly along the frontal boundary. Sunday night will remain mostly cloudy, with temperatures in the middle 50s and a 70 percent chance of precipitation. Monday will feature widespread cloud cover with periods of showers and thunderstorms and temperatures in the lower to middle 70s. Additional showers and thunderstorms will remain possible Monday night, with temperatures falling into the lower to middle 50s.
Rainfall amounts are expected to remain modest overall, although locally heavier rainfall could occur with any thunderstorms or areas of enhanced lift along the frontal boundary. At this time, the system is not expected to provide enough rainfall to significantly improve ongoing drought conditions. Confidence is relatively high that rain will occur Sunday into Monday, but there remains greater uncertainty regarding the total rainfall amounts and the coverage of thunderstorms.
Surface high pressure is expected to build into the region Tuesday and Wednesday, bringing some improvement in conditions. However, upper-level troughing will remain over the area and could produce additional chances for showers. Tuesday will be partly sunny with temperatures in the lower 70s and a 30 percent chance of showers. A few showers could linger into Tuesday evening, although most of the night should remain dry, with temperatures in the lower to middle 50s. Overall, the pattern will remain unsettled into the middle of next week, but widespread rainfall is not currently expected.

Heavy rain and severe thunderstorms will affect parts of the Midwest and Ohio Valley today, with the greatest concern for flooding and damaging storms across the mid-Mississippi Valley. Storms will shift eastward Thursday, bringing a threat for locally heavy rain and thunderstorms from the Mid-Atlantic toward the coast. Meanwhile, monsoonal thunderstorms will remain active across the Southwest, with a greater flooding threat in southern Arizona. Dangerous heat will continue across the South and Southwest, where record-breaking temperatures and very warm overnight lows are possible. Extreme Heat Warnings remain in effect across portions of the Southwest and southern Plains, while heat advisories cover much of Florida and the Southeast coast. Residents should stay hydrated, limit strenuous outdoor activity, and check on those vulnerable to extreme heat.
Severe thunderstorms are possible this afternoon and evening across parts of the Mid-Mississippi Valley, where a few storms could produce damaging wind gusts and large hail. The greatest threat is expected across southern Missouri and nearby areas, where storms may organize into lines and continue into the evening. Isolated severe storms are also possible from the lower and middle Missouri Valley into the Great Plains, mainly producing strong wind gusts and hail. Farther south, thunderstorms may produce isolated damaging winds across southern Arizona and parts of the Southeast. Storm coverage will generally be scattered, but locally strong storms could develop quickly during the afternoon as temperatures and humidity increase. Residents in affected areas should monitor weather conditions and be prepared to seek shelter if severe thunderstorms approach.

Heavy Rain and Repeated
Thunderstorms Bring Flash
Flood Threats From the Central
Plains to the Ohio Valley,
With Additional Flooding
Possible in Arizona and
Florida
Periods of heavy rain
and thunderstorms will bring a
heightened risk of flash
flooding across parts of the
Central Plains, Mid-Mississippi
and Ohio Valleys today into
early Thursday. The greatest
concern is from eastern Nebraska
and northern Missouri into
southeastern Missouri, southern
Illinois, western Kentucky, and
parts of Tennessee, where
repeated thunderstorms could
produce 1 to 2 inches of rain
per hour. Some locations could
receive 2 to 4 inches, with
locally higher amounts possible.
Farther east, saturated soils
and swollen rivers and streams
will increase flooding concerns
across parts of Indiana and
Ohio. Heavy thunderstorms are
also expected across southern
Arizona, where slow-moving
storms could cause flash
flooding in desert and urban
areas. Additional localized
flooding is possible across
Florida and southeastern
Georgia, where very heavy
tropical downpours are likely.

Hot and dry weather will continue across much of the Intermountain West and southern Plains today as high pressure strengthens overhead. Temperatures will reach the upper 90s to 100s across many areas, with some locations in the southern Plains reaching the low 100s. Very low humidity, generally around 15 to 20 percent, combined with dry, drought-stressed vegetation will create locally elevated wildfire concerns, especially where winds increase. A few isolated showers may develop over the higher terrain of the Great Basin as some monsoonal moisture lingers, while deeper moisture remains across the Desert Southwest. A weak front will drift southward into the Texas Panhandle and Oklahoma, but its exact timing remains uncertain. Any thunderstorms developing along the front could produce locally gusty winds and briefly higher fire weather concerns.

The vast majority of weather apps are automated without human oversight and can miss critical, nuanced details during severe or changing weather. Do not rely on an app for the forecast. Instead, go to weather.gov for the foreca
Radar apps visualize precipitation intensity using color-coded echoes. However, updates are not instant, and even the most advanced composite radar mosaics can be delayed by 5 to 20 minutes by the time they reach your app.That delay means the weather you are viewing might already be miles away — or more intense than the image suggests.
