Following the surge in warmth in coastal areas and the central Appalachians on Thursday, temperatures will again bottom out at cold levels in the Northeast this weekend.
After a taste of spring weather in many areas on Thursday, the weather will slide back into winter mode for a time this weekend.
Friday will be the transition day to the change to colder weather.
While far from the monthly minimum set during the first week of the month, temperatures will drop to 10-20 degrees below average for late March this weekend.
Temperatures are forecast to drop into the teens on Saturday night in much of the Appalachians and in upstate New York.
On the Atlantic coast, temperatures will plunge 40-50 degrees Fahrenheit from their highs on Thursday to forecast lows on Sunday. Lows along the Interstate-95 corridor will be in the 20s.
A frost or freeze will even plunge into interior areas of the South this weekend.
Snow will also accompany the cold air in some locations.
The combination of lingering moisture and a weak disturbance moving through will produce flurries and locally heavier snow showers over the central Appalachians to part of the mid-Atlantic and southern New England coast during the first part of the weekend. Enough snow could fall to coat the ground in some of the heavier snow showers.
While most major highways and roads in urban areas will be wet where it does manage to snow, there can be some slushy and slippery spots, especially where the snow falls at night or first thing in the morning.
Temperatures will recover somewhat on Sunday. However, in most areas, temperatures will remain below the late-month average. Highs on Sunday will range from the upper 30s in the northern tier to the 40s in much of New England and the central Appalachians to the lower 50s in the Chesapeake Bay region.
During the tail end of the weekend, another weak disturbance will push eastward from the Midwest. Snow showers could be significant enough to coat the ground from the central Appalachians to the lower Great Lakes on Sunday night.
