Temperatures are more than 35 degrees colder Wednesday morning than they were a day earlier, with wind chills in the 20s and 30s forecast into the afternoon.
After reaching a high of 70 degrees at Baltimore-Washington International Thurgood Marshall Airport late Tuesday morning, temperatures dropped to 28 degrees at the airport early Wednesday morning. By about 11 a.m., 24 hours after that 70-degree high was hit, it was 37 degrees at BWI.
Afternoon highs are forecast in the upper 40s Wednesday. Sunny skies are expected to help things feel slightly warmer throughout the day. But with 15-25 mph winds from the northwest, it was expected to feel as much as 10 degrees colder throughout the day.
Lows are expected in the upper 20s to around 30 degrees early Thursday morning, with afternoon highs again in the upper 40s. Increasing clouds are forecast, with precipitation expected to move in overnight.
Cold rain or possibly a wintry mix is forecast after midnight into early Friday morning, with rain continuing into the afternoon. Lows are forecast in the lower to mid-30s with highs in the lower 40s.
The National Weather Service is forecasting less than an inch of snow accumulation along the Interstate 95 corridor for the first day of spring, and an inch or two to the north and west. Up to 3 inches are possible along the Mason-Dixon Line.
But any accumulation is likely to be washed away by rain expected during the day Friday, or to melt away over the weekend.
More seasonable weather is forecast Saturday, with highs again in the upper 50s with sunshine. More cold is expected Sunday, with highs in the 40s and lows in the 20s by Monday morning.
