MESSAGES WILL BE EXTENDED UNTIL MIDNIGHT
A few additional moderate showers/isolated thunderstorms persist
over portions of the District at this time and will result in Messages
to be extended until midnight tonight. Storms have generally decreased
in strength, however with dew points in the low to mid 50s, combined
with some upper-level support late this evening, the threat will
remain for brief moderate to heavy rainfall. The largest threat will
be a quick 0.5” in 10-20 minutes, rather than any long-lasting
rainfall. A chance for off and on showers will remain through
midnight, although the threat of any moderate to heavy rainfall should
subside over the next couple of hours. Message 1s may need to be
extended beyond midnight if thunderstorm activity does not diminish in
a timely fashion.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers/thunderstorms
will produce a trace-0.25” total in 10-30 minutes.
WORST CASE SCENARIO: A moderate to strong shower/thunderstorm will
produce 0.25”-0.75” total in 10-30 minutes.
