PM Update: Satisfactory Saturday, but rain and snow at night into Sunday

Today marked the 12th straight day with above average temperatures and we’ll add another Saturday. But late Saturday, low pressure approaches from the southwest, initially bringing light rain. And by early Sunday morning, that light rain may mix with and change to snow. Sunday - for a change - looks wintry, with morning snow (or rain/snow mix south) and chilly temperatures.

Through Tonight: No weather worries at all. Just a few clouds and chilly temperatures. Overnight lows range from near 30 in the colder suburbs to the mid-to-upper 30s downtown. Winds are light.

Saturday: We awake to some sunshine, but clouds lower and thicken by afternoon. There’s a 20-40% (east to west) chance of light rain by late afternoon, with highs 45-50. Winds are from the north at 5-10 mph.

Saturday night: Patchy light rain is likely (60-70% chance), possibly mixing with and changing to light snow by morning. The best chance of a changeover is north and west of the District. Lows range from 32-37 (lowest northwest and highest from the District to the southeast). Little or no snow accumulation is likely.

Super Bowl Sunday: Snow (north and west of the District) or a rain/snow mix (from the District and south and east) is possible (50-60% chance) in the morning before precipitation tapers off in the afternoon. The best chance of accumulating snow is in Loudoun and Frederick counties. Elsewhere, a light coating on grassy areas (if that) is more likely. Temperatures are chilly, with highs 35-40 (lowest northwest and highest from the District to the southeast).

Confidence in the Sunday snow forecast is low. For more details, see our earlier post. Note: We will post an update with an accumulation graphic this evening before 11:15 p.m.

Colorado snow amounts: A powerful winter storm continues to belt eastern Colorado and the central Plains. (The remnants of this storm will bring us the mix of precipitation discussed above). Through mid-afternoon local time, Denver had received about 11” of snow but several locations in the mountains had already piled up 20-35”. Get the latest totals from the National Weather Service.
