| Once again, there is very little change to the overall pattern as multiple rounds of rainfall are expected to move in from the east throughout most of the day today. Dew points are currently in the low to mid 50’s throughout the District and will likely hold in place through the rest of the day. These elevated surface dew points will suggest moderate to heavy rainfall possible from just general showers, similar to yesterday morning. Training of rain showers will also play a key component today as multiple rounds of showers could lead to rainfall in excess of 1” per hour today. The best chance for storms will be from now, picking up once again through the morning, with rainfall chances possible well into the evening. The best chance for widespread moderate to heavy rainfall will be now through this afternoon. Like yesterday, due to the lack of daytime heating, thunderstorm activity should remain minimal, however a few embedded thunderstorms cannot be completely ruled out today. Storm motions will once again be atypical, moving in from the east and pushing up against the foothills. This storm motion will result in a MODERTE chance of Message 1’s being issued today, mainly for the threat of 1” per hour rain, however, a quick 0.5” in 10-20 minutes cannot be completely ruled out today, especially if thunderstorms are able to develop. |
WORST CASE SCENARIO: An anchored thunderstorm, or training of moderate to heavy showers
has the potential to produce up to 2.6” in 60 minutes.
A LOOK AHEAD: This unusual pattern will finally start to break down tomorrow as upper-level flow shift back to a more typical west to east pattern. A chance will remain for showers and thunderstorms tomorrow, however drier air from the NW should help limit the available moisture, effectively decreasing the chances for heavy rainfall. Next week will resume a more seasonable pattern with high temperatures back into the 70’s along with afternoon/evening rain/isolated thunderstorm chances through the week.
