Washington is waking up under partly cloudy skies and a brisk 46°F at Reagan National Airport, but the calm is temporary. Afternoon highs are set to climb into the upper 50s to near 60°F as easterly winds turn breezy, and a few showers could sneak in late tonight. Consider it the warmup act before a far more potent system arrives on Monday, March 16, 2026.
Severe Storms Possible Monday
The region has been placed under a Moderate Risk for severe weather on Monday, March 16, 2026, signaling a heightened chance of widespread damaging winds and some tornadoes, according to the Storm Prediction Center. Forecasters expect the most dangerous window to run from the afternoon into the evening commute, when storms may organize either into a fast-moving line or as discrete severe cells. Anyone with outdoor plans is urged to keep a close eye on watches and warnings overnight into Monday.
Timing and Rainfall
Rain showers are projected to move in late tonight, generally between 8 p.m. and 11 p.m., then evolve into showers and thunderstorms through the overnight hours with lows in the low 50s. Monday should begin with lingering showers before storms become more numerous during the afternoon and evening. Forecasters with the National Weather Service Baltimore/Washington office note that new rainfall amounts of roughly three quarters of an inch to one inch are possible during the day Monday, with an additional 1 to 2 inches possible Monday night in some locations. Those totals could trigger localized urban or poor-drainage flooding where heavy cells repeatedly pass over the same neighborhoods.
Afternoon Winds and the Commute
Southerly winds will strengthen ahead of the front, with non-thunderstorm gusts commonly reaching 25 to 35 mph. Within stronger storms, much higher momentum winds could be dragged down to the surface, and forecasters warn that isolated gusts could reach about 55 to 75 mph in the most intense cells. The result could be tree damage, scattered power outages, and slowdowns during Monday afternoon and evening peak travel. Build in extra time for commutes and avoid parking under large trees if possible.
Boaters and Tides
Small Craft Advisories are posted beginning this morning and lasting into Monday, so mariners should expect increasing southerly winds and rougher conditions on the Bay. Strong onshore flow ahead of the front may also push tide levels higher during Monday afternoon and evening high tide, with vulnerable locations likely to reach or approach minor tidal flooding. Annapolis is specifically highlighted as being within minor flood stage and could reach moderate flooding if onshore winds are stronger.

What to Do Now
Make sure phones and weather apps are set to receive alerts, and have a simple plan to head indoors quickly if warnings are issued on Monday, March 16, 2026. Secure loose outdoor items, steer clear of waterfront areas during the evening high tide, and consider delaying outdoor activities. If you need to travel, check for transit advisories, give yourself extra time, and be ready for the possibility of power outages or blocked roads.
