Clouds gradually increased as temperatures crept into above average territory this afternoon, reaching the mid-to-upper 40s. A disturbance scoots through the region tonight with some rain and snow showers to be followed by yet another Saturday night. Temperatures – on balance – are on the wintry side.

Through Tonight: Cloudy this evening with a 40-50 percent chance of rain and snow showers after 9 p.m. In the immediate area, it’s likely rain showers to start, mixing with and changing to snow after midnight. Towards western Montgomery County and Loudoun county and to the west and northwest, it’s mostly snow showers. For the immediate metro region, expect little or no accumulation. In Frederick, western Montgomery, and Loudoun counties, a dusting to an inch (mainly in higher terrain) is possible. Lows range from the low-to-mid 20s in the cooler suburbs to near 30 downtown. Note: with falling temperatures overnight, a few slicks spots can’t be ruled out early in the morning as wet spots could ice over.

Tomorrow (Saturday): Mostly sunny, breezy, and cold. Highs only reach the mid-30s, and it feels like the 20s factoring in winds from the west at 10-20 mph.

Saturday night: Clouds increase in the evening, with a 20-30 percent chance of snow showers, mainly after midnight, and especially towards dawn. Temperatures are subfreezing, so anything that falls will stick. But amounts are likely to be very light; so accumulations, if any, are most likely in the dusting category. Lows range from 20-25.

Sunday: Widely scattered snow showers or flurries depart early, then it becomes partly sunny and breezy. Highs are close to normal, from the upper 30s to low 40s. Winds are from the west at 10-20 mph.
