NoVA/DC Weekend Weather Forecast for January 15, 2021

After a cool, calm week, we are finally getting some precipitation that we haven’t seen in a while tonight. The past few days have been dry as temperatures were in the upper 40s and reaching the lower 50s in some places. Radar pictures tonight show a large swath of rain sweeping over the area, with the heaviest rain in and around Baltimore.

Rain will continue tonight, possibly mixing with some snow due to the cold high up in the atmosphere, but no meaningful accumulation is expected. Low will be around 30. For tomorrow, there is again a slight chance of a rain/snow mix on the backside of the front moving through the area tonight. Surface temperatures won’t be cold enough to support any sticking in the immediate area, but for points Winchester and west, temperatures will be lower so a coating to an inch is possible. Winter Weather Advisories will likely be issued for the Allegheny Front where more significant snow accumulation is expected along with the possibility for snow squalls. Across the area right now, no major notices have been issued.

Saturday will be mostly cloudy as the low continues to pass through overhead, with highs in the low to mid-40s. Low around 30. As the upper low passes through, winds will be on the rise on Sunday. Wind gusts around 20 mph expected, along with mostly sunny conditions. Highs in the mid-40s, low around 30. As a new front moves into the region Sunday night, there is a possibility of some snow showers to develop during the day on Monday. Otherwise for the Monday holiday, it will be mostly sunny with highs in the low 40s, low around 28.

My forecast for the week ahead will be issued on Sunday afternoon. Have a great long weekend!
