-------------------------
MESSAGE 1'S WILL BE ALLOWED TO CONTINUE UNTIL 8PM
-
Message 1's will continue valid until 8pm as additional rain
showers/thunderstorms develop over the foothills at this time.
-
Strong to severe storms that impacted the District this afternoon
have moved N/NE and are no longer a threat to the District. Additional
storms have developed to the west along the foothills and will slowly
move N/NE and into northwestern portions of the District over the next
few hours. Storm motions will continue to be fairly quick between
10-20mph which will also help limit point rainfall amounts.
-
Storms have diminished in intensity at this time, but the threat
still remains for brief heavy rainfall with a very slight chance for
severe weather, including large hail, gusty winds and frequent
lightning.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers and
thunderstorms will have the potential to produce TR-0.3" in 10-30
minutes. Strong thunderstorms will have the potential to produce
0.3-0.7" in 10-30 minutes.
WORST CASE SCENARIO: An anchored strong thunderstorm or training of
thunderstorm cells may result in up to 1.5" of rain in 45-60 minutes.
