Delaware – Cold, clear air settles over the region this morning, but winter weather is already lining up its next move. Clouds increase later, and by Saturday, moisture pushes in just as temperatures hover near freezing, setting the stage for slippery conditions.

According to the National Weather Service, light snow is possible later today, with a better chance Saturday as rain mixes with snow. Highs climb into the low 40s Saturday, but that warmth is short-lived. As colder air filters back in Saturday night, slushy roads may refreeze quickly.

Across northern Delaware, impacts remain light but tricky. In Wilmington, bridges, ramps, and untreated streets could turn slick after sunset. Drivers on I-95, Route 202, and local arterials should slow down and allow extra braking distance.

Saturday night brings a slight chance of freezing rain before precipitation transitions back to snow. Even small amounts can create problems, especially with temperatures near 29 degrees. Sidewalks and parking lots may become icy by early Sunday.

Sunday stays cold with a chance of snow and highs near 36. Lingering moisture raises black ice concerns through the evening. Conditions calm Sunday night, but the cold deepens as skies clear and lows drop into the lower 20s.

MLK Day offers a quieter stretch. Sunshine returns with highs near 36, though the air remains brisk. Monday night dips into the teens, locking in a hard freeze. Tuesday stays sunny but colder, with highs only reaching the mid-20s.

Meteorologists are watching a broader winter pattern next week, as cold air remains entrenched across the East and additional precipitation chances may return.
