Welcome Rainfall Overnight

Rain has overspread all of central Virginia, and will continue overnight. Most areas will receive between 0.25" and 0.50", which will be the most rain than we have seen in a 12-hour period in Richmond over about the past month. A strong upper-level low will take it's time moving this way, bringing several rounds of rain to the area through Saturday night. It will be interesting to see what happens as the cold core moves right over Virginia on Sunday. I've seen situations like this produce wet snowflakes mixing in with rain showers with surface temperatures in the upper 40s and low 50s. There will be a much better chance of that happening farther west in the higher terrain. It looks like we could see a cool snap in about 11 to 13 days from now, but it should be very brief.
