| Message 1’s have been issued for the entire District effective until Cooler and cloudy to start the day as a disturbance is poised to move over the District throughout the day today, through the evening with a slight chance for some overnight showers/isolated thunderstorms. Currently temperatures are in the low 60’s with highs expected in the upper 70’s to around 80 this afternoon. Dew points are currently elevated, in the mid to upper 50’s and will likely remain as the day progresses resulting in a good chance for isolated heavy rainfall today. Showers and thunderstorms have already initiated over portions of the District and will likely continue through the afternoon and evening. The best chance for storm activity within the District will be from NOW through midnight, with a few lingering showers through the overnight, tapering off between 2-4am. Multiple rounds of showers/thunderstorms will be possible this morning, afternoon and evening. Storm motions will be the typical W to E motions between 15-25mph which should help limit point rainfall amounts with some erratic storm movement possible off outflow boundaries. Storms may also contain large hail, strong winds, frequent cloud-to-ground lightning and possible an isolated land spout/weak tornado, mainly for eastern portions of the District, especially if temperatures increase into the 80’s. |
WORST CASE SCENARIO: A strong thunderstorm anchors off an outflow boundary, or training of
thunderstorms could potentially produce up to 2.0” total in 45-60 minutes.
