7-Day Outlook: August 20–26, 2026
High pressure will settle over the region Friday into Saturday, bringing mostly clear to sunny skies and generally quiet weather. Areas of morning fog will be possible both days, followed by pleasant afternoons with highs in the low to mid-70s Friday and mid-70s Saturday. Winds will be light, becoming west around 5 mph Friday afternoon and southeast around 5 to 10 mph Saturday morning. Clear skies and light winds Friday night will allow temperatures to fall into the mid-40s, with patchy fog possible after midnight.
An occluding low pressure system to the west and a coastal low moving north from the Mid-Atlantic will begin to affect the region Saturday night into Sunday. Clouds will increase Saturday night, with a chance of showers developing after midnight. Southeast winds will be around 5 to 10 mph, and overnight lows will be in the upper 50s. Less than a tenth of an inch of rainfall is expected Saturday night, although precipitation chances will increase as the coastal system approaches Sunday.
Showers will remain likely Monday as the Quebec low lifts north of the region, with scattered thunderstorms possible during the afternoon. Mostly cloudy skies will continue, with highs in the mid-70s and a chance of showers and thunderstorms around 70%. Activity will gradually diminish Monday night, although a few showers or thunderstorms will remain possible before midnight. Lows will fall into the low 50s.
Surface high pressure will begin to build over the East Coast Tuesday into Wednesday. A large upper-level low tracking toward Labrador will keep a slight chance of showers across the Valley Tuesday, along with the possibility of an isolated afternoon thunderstorm. Partly sunny skies and highs in the low 70s are expected. Clouds will diminish Tuesday night, with lows in the low 50s.
The upper low will move farther away Wednesday as high pressure takes greater control of the region. Mostly sunny skies will return, with highs in the mid-70s. Partly cloudy skies are expected Wednesday night, with lows in the low to mid-50s.

A widespread weather pattern will bring heavy rain, flooding, severe thunderstorms, and dangerous heat across the country. Heavy rain and thunderstorms will shift from the Ohio and Tennessee Valleys to the Mid-Atlantic today, with a risk of flash flooding and damaging wind gusts. Additional heavy thunderstorms are expected Friday across the Carolinas, Mid-Atlantic, and Southeast. Severe storms are also possible from the central Plains into the Upper Midwest, with large hail and damaging winds the primary threats. Meanwhile, dangerous heat will continue across the South and expand into the Southwest, with some areas facing record temperatures and exceptionally warm nights. Extreme Heat Warnings remain in effect across portions of the Southwest, southern Plains, and Deep South. Monsoonal thunderstorms will also affect the Four Corners region.
Scattered severe thunderstorms are possible today and tonight across parts of the Mid-Atlantic, Midwest, and central Plains. The greatest concern in the Mid-Atlantic is damaging wind, although a few tornadoes and large hail are also possible, especially from southern Pennsylvania through Maryland and New Jersey. From Nebraska into Minnesota and Wisconsin, storms could produce large or locally very large hail, damaging winds, and an isolated tornado. Additional thunderstorms are expected across the Southeast and lower Mississippi Valley, where heavy rain and strong wind gusts could occur. Arizona will also see scattered afternoon and evening thunderstorms, with a few storms capable of producing strong wind gusts. People in affected areas should monitor weather conditions and be prepared to seek shelter if severe storms develop.

Heavy
Rain and Flash Flooding
Threaten the Mid-Atlantic
A round of
thunderstorms could bring heavy
rain and flash flooding to parts
of the Mid-Atlantic today,
especially from Baltimore and
Philadelphia to New York City
and northern New Jersey. Storms
are expected to develop along
and ahead of a cold front this
afternoon before moving
eastward. Some storms could
produce very heavy rainfall in a
short period, with localized
rainfall rates of 1 to 3 inches
per hour or higher. Urban areas
are particularly vulnerable
because of extensive pavement
and limited drainage. The threat
is greatest along and east of
Interstate 95, although the
exact location of the heaviest
rain remains uncertain.
Scattered thunderstorms will
also affect the Southwest and
southern Rockies, with flash
flooding possible in areas near
mountains, burn scars, slot
canyons, and normally dry
washes.
🔥Fire Weather Outlook🔥
Learn more about Fire Weather Outlooks
A low-pressure system aloft will keep unsettled weather over the Northeast today, while an additional disturbance brings higher chances for rain across northern Minnesota and Wisconsin. Rain will be especially beneficial in areas experiencing drought, although amounts may vary considerably. Meanwhile, high pressure will strengthen over the Great Basin, bringing warmer-than-normal temperatures and generally dry weather across much of the Interior West. An area of low pressure will deepen along the West Coast, increasing southwest winds across the Northwest. These conditions may briefly raise the risk of wildfire growth in parts of the Intermountain West this afternoon, but widespread critical fire weather is not expected.

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.
