SATURDAY NIGHT: WINTER ALERT
Increasing Clouds, Wintry Mix Begins

Sunday turns cloudy and chilly with wet weather developing during the morning. It likely starts as rain or a rain-snow mix, and stays mostly light through the day. Temperatures hover in the mid 30s, so any snow has a tough time sticking except on grass and at higher elevations. A winter storm watch is posted for northwestern Montgomery, Western Loudoun and Frederick counties. Sunday night is the main window to watch as colder air works in and the mix changes to steadier snow during the evening. Light to occasionally moderate snow continues overnight, with the steadiest snow most likely north and west of D.C.; and farther to the northeast over New Jersey. By Monday, the snow tapers around daybreak. Gusty winds and colder air follow, with a few leftover slick spots early before conditions gradually improve.

MONDAY:
Scattered Clouds, Blustery
Highs: 35-40
Winds: Northwest 10-20, Gusts to 30 mph
Monday looks colder and breezy as the storm pulls away. Any leftover snow or rain early should taper off, with clouds gradually breaking. Highs stay chilly, mainly the upper 30s to lower 40s along with gusts to 30 mph at times.

TUESDAY:
Partly Cloudy, Breezy
Highs: 35-40
Winds: Northwest 10-20 mph
