It looks like temperatures the next couple of days will be near or below seasonal averages. The breeze will stay up on Tuesday, with temperatures nearing 50 degrees during the afternoon. All attention is on the Alberta Clipper that will zip across the region on Wednesday. Moisture in advance of this system will run into dry air east of the Blue Ridge, but may still be able to produce snow showers Wednesday morning, especially along and north of I-64. Systems like this often don't produce a lot of precipitation, and this one won't be an exception. In fact, little if any precipitation is likely south of the Metro Richmond area. While we may see some of the first snowflakes of the season early on, the lower levels of the atmosphere will be warming during the daylight hours and any flakes may turn to raindrops. So snow lovers shouldn't get too excited.
The end of the week into the weekend...
Temperatures behind this system will stay in the chilly 40s on Friday, but we'll be warming up by the weekend as an upper ridge builds over the Southeast. This will probably help to boost temperatures into the 60s Sunday and Monday.
Looking ahead to next week...
The building upper ridge will lead to several days of very mild weather. An approaching front from the west will slow down, but eventually reach the Commonwealth Tuesday or Wednesday. This front will hopefully bring some rain to the area, followed by a little cooler air. However, our longer range model data shows the upper flow rather zonal (west to east), meaning temperatures will likely stay at or above average through at least the following weekend (Dec.15-16).
