WEATHER BLOG: Saturday

It was a dry, cool end of the week under mostly cloudy skies and temperatures well below normal for the beginning of May. The Baltimore-Washington International Airport reached 57 degrees F after a morning low of 48 degrees.

Heading into the weekend, the upper-level area of low pressure responsible for the scattered showers during the end of the week will slowly progress eastward off the mid-Atlantic Coast. Saturday will feature another day of a spotty shower across the area, mainly during the afternoon hours.

An area of high pressure currently across the lower Mississippi Valley will shift eastward and bring dry conditions to the area from Saturday night through Monday. Warm air from the Gulf of Mexico will build into the Eastern U.S. for Sunday and Monday with temperatures well above-average.

A storm system currently across southern Saskatchewan will move northeastward towards the northern Hudson Bay. A frontal boundary is expected to stall across the area and develop showers and thunderstorms for Tuesday. There is disagreement with the models in terms of location of the front and therefore the precipitation. If the GFS model is correct, the front may stall north of the city and precipitation will also remain to the north. If the EURO model is correct, temperatures maybe cooler due to the front stalling across the city with showers possible.

By the middle of next week, a warm front will move northward and bring another shot of warm air across the region.

Temperatures will remain above-average for the beginning of May across the region.

Have a good day!
