7-Day Outlook: August 16–22, 2026
Clouds will increase tonight as a weakening occluded front approaches from Quebec. Scattered showers will develop, mainly after the early morning hours, with a 30% chance of precipitation. Temperatures will fall into the mid-50s, with light winds becoming southerly around 5 mph after midnight.
The front and its associated low pressure system will cross the region Monday, bringing some beneficial rainfall to the Valley. Showers will become likely, and thunderstorms will be possible during the afternoon. Cloudy skies and southerly winds of 5 to 10 mph will accompany the rain, with a 70% chance of precipitation. Rainfall totals of 1/4 to 1/2-inch are possible, with locally higher amounts in thunderstorms. Temperatures will reach the upper 60s.
Showers will continue into Monday evening as the low pressure system and upper-level trough move through the region. A thunderstorm will remain possible during the evening, although precipitation will taper to a slight chance after midnight. Patchy fog may develop late, with light and variable winds. Additional rainfall will generally be less than 1/10-inch, although thunderstorms could produce locally higher amounts. Overnight temperatures will fall into the mid-50s.
High pressure will build in from the Ohio Valley on Tuesday, bringing improving conditions. Skies will become partly sunny, winds will remain light, and temperatures will climb into the mid-70s. Tuesday night will be mostly cloudy, with calm winds and temperatures in the mid-50s.
Showers and thunderstorms will remain likely Wednesday evening before tapering to a few lingering showers overnight as the front moves through. Skies will remain mostly cloudy, with temperatures falling into the low to mid-50s. Rainfall totals will generally remain below 1/2-inch, with lighter amounts expected Downeast.
Thursday will bring improving conditions behind the front, with mostly sunny skies and temperatures in the low 70s. A few showers will remain possible, along with an isolated thunderstorm during the afternoon, but the overall chance of precipitation will be low. Skies will clear Thursday night, with temperatures falling into the upper 40s to around 50.
Friday will be sunny and pleasant, with temperatures in the low to mid-70s. Mostly clear skies will continue Friday night, with lows around 50.

Severe thunderstorms, heavy rainfall, and flash flooding remain possible from the Midwest to the central Appalachians and across the central High Plains. West Virginia faces the greatest flash flood threat, with additional flooding possible in the Mid-Atlantic. Storms may also become severe across the High Plains, where heavy rain could cause flooding near steep terrain, burn scars, slot canyons, and urban areas. Conditions will gradually improve across the Great Lakes and Northeast Monday as drier air arrives behind a cold front. Meanwhile, dangerous heat will persist across the South and Southeast through the week, with afternoon temperatures in the upper 90s to mid-100s. High humidity could push heat indices as high as 115 degrees, creating widespread major to extreme heat risk.
A slight risk of severe thunderstorms is in place across parts of the Ohio Valley, central Appalachians, Mid-Atlantic, and central High Plains. Storms developing this afternoon could produce damaging wind gusts, with the greatest wind threat extending from the Ohio Valley into the Mid-Atlantic through early evening. A few organized storms may also produce large hail and isolated tornadoes, particularly across southern Ohio and northern Virginia. Storms will move eastward into West Virginia and the Mid-Atlantic later today. Across the northern and central High Plains, scattered thunderstorms could produce large hail and strong wind gusts, especially near higher terrain. Severe weather is expected to remain isolated overall, but residents in affected areas should monitor forecasts and be prepared for rapidly changing conditions.

Significant
Flash Flood Threat Continues
Across West Virginia and Parts
of the Mid-Atlantic
A moderate risk of
excessive rainfall is in effect
across portions of West
Virginia, where multiple rounds
of thunderstorms could produce
significant flash flooding today
and tonight. Very moist air and
persistent moisture flowing into
the mountains will support heavy
rainfall, with some storms
repeatedly moving over the same
areas. A slight risk extends
into parts of Pennsylvania,
Maryland, and Virginia, where
localized flash flooding is also
possible, especially in urban
areas. Additional storms across
the Ohio Valley into Missouri
could cause isolated flooding
where soils are already
saturated. Farther southwest, a
slight risk covers portions of
northeastern New Mexico and
southeastern Colorado, where
slow-moving thunderstorms could
produce heavy rain and localized
flash flooding.
🔥Fire Weather Outlook🔥

No critical fire-weather areas are expected today. A weakening ridge and several upper-level disturbances will shift moisture and thunderstorms across parts of the West and southern Plains. Scattered showers and thunderstorms are expected across the Texas Panhandle and Oklahoma, where gusty and erratic winds may accompany storm outflow. Some storms could produce lightning near dry fuels, although increasing moisture should limit the risk of dry thunderstorms. Farther north, monsoon moisture will shift into Idaho, Montana, and Wyoming, where recent rainfall has reduced fuel receptiveness and many storms should produce wetting rain. Parts of southern Oregon, northern Nevada, and northeastern California could experience warm, dry, and breezy conditions, with wind gusts around 10 to 15 mph. Overall, 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.
