Adieu, April: Winter Snow & Cold Return
Potential for 1-3"; greatest amounts south & east

A. Camden Walker @ 12:40 PM

** Snow Advisory and Freeze Warning in effect from midnight tonight to 10 AM Saturday **

What the...?! A coating of snow greeting my wake-up Saturday morning?! It could happen. A quick-hitting April storm is poised to produce accumulating snow tonight into tomorrow morning.

This Afternoon

Forecast Confidence: HighMarch-like Rawness. Clouds will be on the increase as temperatures struggle to reach the mid-40s, to perhaps 50 south of town. Heavy coats recommended (duh), along with ear muffs to battle against the windchill.

Tonight and Tomorrow

Forecast Confidence: HighWintry. No Joke. Winds will begin to calm as temperatures slowly drop through the 30s tonight under overcast skies. As a late-season wintry storm develops off the coast, light snow could begin to fall as soon as midnight, followed by periods of snow (and reinvigorated winds out of the north) into the morning hours on Saturday (See Snow Lovers Crystal Ball at the bottom of post for more commentary.) After the snow quits, temperatures will rebound slightly -- toward 40 degrees in the afternoon. Windchills will be in the 20s, however. Hope you know where that scarf is.

Still Chilly. Snow showers and wind will still pester us before sunrise; but, Mother Nature, WE GET IT -- winter still wants a vote. Temperatures heading up toward 50 degrees will be chilled by some serious wind -- frosty 30s will be what you probably feel.

Next Chance of Accumulating Snow:
Tonight through Saturday AM
Probability: 60%
Potential Impact:

Commentary: A strong, fast-moving disturbance swinging through the region is expected to spawn a surface low-pressure area and strengthen off the Virginia coast. The result for the DC metro area is likely to be periods of snow between midnight tonight and late Saturday morning. It may start briefly as rain or a rain/snow mix, but changing quickly to snow given very cold temperatures in the atmosphere above us.

The best chance of accumulation would be on grassy surfaces. But road surface accumulations are possible since much of the precipitation is expected to fall before sunrise. The heaviest precip is most likely to be south and east of town. Here are the overall probabilities for the metro area, with the highest amounts expected south and east:

20%: 1" or less
35%: 1-3"
30%: 2-4"
15%: 4"+

All in all, forecast confidence is improving; but some uncertainty remains in the latest model data. will monitor the situation.
