Rain For Election Day...

If you've been following my forecast the last couple of days, you know I've been concerned about coastal development and the potential for rain to dampen Election Day. Well it's happening now, as moisture is quickly invading Southeast and Central Virginia. A steadiy rain will be developing and continuing through the day. Looking at the latest NAM model forecast for the early afternoon, you can clearly see a coastal trough spreading moisture over much of the region. A coastal low will develop that should bring a pretty good dousing to the area. The latest computer model output is showing some impressive numbers. The evening run of the NAM model puts out about 0.75" by 7 P.M. Tuesday evening, with another 0.56 through Wednesday evening. The GFS (from this afternoon's run), which was the first model hinting at a wet Election Day, shows 0.68" by 7 P.M. Tuesday and another 0.90" by Wednesday evening. So both main short range models show the potential of a good inch and a half of rain.

Clearing and milder later in the week...

Looking at the 72-hour forecast chart from the NAM below, a distinct area of low pressure is moving away from the East Coast. This will allow our skies to clear on Thursday, with temperatures heading to near 70 degrees. The mild weather will continue into Friday, before the next cold front arrives to bring another change over the weekend.
