Thursday, April 2, 2009 Forecast

...Dense fog advisory in effect until 9AM EDT this morning...

Currently sitting at 48°F here in Snowville with foggy conditions. Today, southeast winds will keep us mostly cloudy with the chance of drizzle and rain on and off throughout the day. Total estimated precip for today: <.10". Moisture from the Atlantic will keep us locked in with clouds, so don't expect a big rise in temperatures. NAM model is indicating highs in the upper 60s, but with clouds and the chance of precip through the day, I'm dropping those numbers to the lower 60s...around 61 today. The model is also hinting at the possibility of some upper-level convergence at 700mb, which would bring clearing skies, around 2PM this afternoon. I'm having trouble accepting this with us under SE flow, so I'm keeping the skies cloudy through the day.

Overnight and during the morning hours Friday are the favored time-frames for precip to move in to Southwest Virginia. From midnight tonight until 9AM Friday, our area could pick up between .25" and .50" of rainfall. After lunchtime tomorrow, most areas should clear of any remaining precip as the system exits our region to the north. Winds will be breezy and out of the southwest tomorrow, switching to the northwest in the evening hours and skies should be cloudy during the morning, then becoming partly cloudy in the late afternoon/evening. Tomorrow will again be cooler, with afternoon temperatures in the mid to upper 50s.

High pressure moves in for Saturday, which should provide us with sunny skies and warmer temperatures. Expect a cool start to the day, but temperatures should rebound nicely to the mid 60s for most locations...the NRV should hit 64. Northwest flow will be breezy at times, and it will prevent any further warming on the day Saturday, but the later-half of the weekend looks to be the warmest.
