Flooding rain threat across the DC area Friday into Saturday
WASHINGTON (ABC7) —
Friday into Saturday will feature the threat for heavy rainfall across the DC area. While the exact placement of the heaviest rain is still in question, the potential for 2-3 inches of rain with locally higher amounts up to five inches may be possible.
Going into this afternoon
We don't like to get ahead of ourselves too much since that's how some weather events are overlooked. We start with added heat and humidity Thursday with highs in the mid to upper 80s and dew points back around 70 degrees.
A few storms may fire after 5 p.m. and continue through 10 p.m. as a boundary moves into the region. A few may be on the stronger side so be sure to have your StormWatch7 App handy later Thursday.
When does heavy rain begin?
A mid-level disturbance will move into our area from the Great Lakes Friday evening into Saturday. We're thinking pockets of heavy rainfall will start Friday early afternoon prior to the commute home.
The heaviest timing appears to be from 9 p.m. Friday night through 9 a.m. Saturday morning. This is the time where you will want to be at home or safely inside somewhere. You don't want to be out traveling in the dark during this period as it will be difficult to spot water over the roadway.
We are certain a Flash Flood or Flood Watch will be issued for the DC area Thursday afternoon. Flooding will be possible for this evening into Saturday. Please remember not to cross flooded roadways and to report instances of flooding to StormWatch7 so we can relay them to the National Weather Service.
There is also the possibility for a few strong storms at the onset of the event Friday afternoon, but the highest likelihood for them would be south and east of DC.
