Pinpoint Weather: More rain on the way Friday into Saturday, heavy at times
There is another complex weather system slated to move over the Commonwealth Friday and Saturday. The timing has been a bit of a challenge but as we get closer to the event the picture is getting clearer. There will be a noticeable increase in the cloud cover tonight as the center of the complex moves in from the south. The flow of air is expected to be from the south and west so the mercury in the thermometer will not dip as aggressively as we saw last night in some spots. Overall, the lows will be in the middle to low 30s east of the Foothills and in the 20s through the NRV and Highlands with a few teens in some localities.
Friday will be a day of transition; the clouds should be in place but may not have filled in completely. By the middle of the afternoon there expect to see cloudy skies along with the potential for light rain. The rain will slowly overtake the Commonwealth but will be more showery in nature until well after sunset.
The rain will be heavy at times overnight Friday into Saturday with the potential for some minor flooding. The flooding will be localized but fairly intense as the storm is expected to drop from 1 – 2” of rain in a relatively short period. Since the ground is cold and the vegetation is dormant, the run off will be much quicker than in the summer, so two inches of rain is going to be a problem. Stay alert if you live in flood prone regions and watch for the rising waters.
Saturday will start out with the storm exiting the area and the skies should be mostly sunny by mid-morning. The Highlands may see some light snow lingering as the storm exits but the main feature to deal with on Saturday will be the wind. Gusts in the 30mph range will be quite common and there may be some power outages as some large limbs or even full trees compromise power lines. Temps will be chilly with highs in the 40s and wind chill values in the 30s.
Sunday will continue with a breezy pattern and a chilly pattern. The next several days after the rain Saturday morning will be dry. Look for a typical December pattern with highs in the upper 40s to low 50s and dry air. A slightly warmer scenario is expected by the middle of the week with highs in the upper 50s.
