WASHINGTON — Keep an umbrella handy for Thursday into Friday. The WUSA9 Weather Watch team is monitoring a storm system that will bring rain, wind and even a few strong thunderstorms, especially later in the afternoon and evening.
There is a small risk for severe storms with damaging wind being the primary threat. On a scale of 1 to 5, this is a level 1 threat.
There is also a low risk for an isolated tornado. The higher risk remains well to our west through the Ohio River Valley. If any rotating storms were to develop across the DMV, it would be later in the evening after 6 p.m. through around midnight.
Winds associated with the storms could still be strong enough to snap a few weak trees and limbs. Gusty winds may also cause some isolated power outages. The rain and wind will also likely lead to altered outdoor plans.
Key Points:
- Critical timing for travel-impacting rain is now - Friday 2 a.m.
- Critical timing for isolated storms with potential damaging winds Thursday 9 p.m. - Midnight Thursday night
- Generally, winds will range between 15 and 25 mph +, with gusts in excess of 58 mph in strong to severe storms
- Main spin-up tornado risk mainly west of DMV
- Minor coastal flooding at the time of high tide on the Potomac River and Chesapeake Bay
Timeline:
Thursday 6 p.m.
On-and-off rain will continue through the immediate DC Metro during the afternoon commute, although the worst weather will move through after sunset. It's during this time there may be damaging winds, brief downpours, and perhaps even a spin-up tornado, especially west of the District.
Midnight Thursday Night
Though severe weather should generally have waned, additional showers along with an embedded thunderstorm are possible through midnight Thursday night into the wee hours of Friday morning.
Friday Morning
Most showers of significance should have already waned by Friday morning, although some leftover wet roads are still possible for the morning commute.
By the time the majority of the rain tapers, up to about a quarter to half an inch will have fallen, with some spots picking up between a half and one inch of rain.
