Brian’s exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Overnight: Mostly cloudy with a low around 35.
Wednesday: Cloudy with occasional rain showers; areas of fog. The high will be 40 to 45.
Wednesday Night: A few rain showers; areas of fog. The low will be near 40.
Thursday: Mostly sunny and breezy. Warmer with a high near 60.
The extended forecast calls for a mostly sunny sky on Friday with a low around 40 and a high near 60. Clouds and sun on Saturday with a slight chance of a rain shower. The low will be in the lower 40s and the high will be in the lower 60s. Breezy and colder with sunshine on Sunday. The low will be in the mid 30s and the high will be in the mid 40s. Mostly sunny and cold on Monday with a low in the upper 20s and the high will be in the lower 40s. A chance of rain and/or snow on Tuesday with a low in the upper 20s and a high in the upper 30s.
During the overnight hours we can expect a mostly cloudy sky, but conditions should remain dry until morning. A warm front will move through the area from south to north on Wednesday, to then be followed by a cold front later in the day. The frontal passage will result in widespread cloudiness as well as rain showers. Morning temperatures will be above freezing, so there is no concern about frozen precipitation. Clouds and rain will hold the mercury down in the lower to middle 40s during the day. Scattered rain showers will continue into the evening hours with some areas of fog developing. The air behind the front will be on a west wind, so highs on Thursday and Friday will surge well into the 50s to near 60 degrees. By Saturday, 60 degrees is not out of the question, but showers may accompany the mild air. The warm-up will be brief, as another wave of arctic air will be poised to move toward the northeast and Middle Atlantic states by Sunday and Monday with highs only in the 40s. Overnight lows will be in the 20s to lower 30s. A storm system may impact the Middle Atlantic region by Tuesday with a chance of rain and/or snow.
