Baltimore and the Washington, D.C. region are bracing themselves for a muggy and potentially stormy couple of days, according to the latest forecasts from the National Weather Service. The week kicks off with a return of high humidity as high pressure moves offshore, offering chances for thunderstorms, particularly along and west of the Blue Ridge today. Information from the National Weather Service reports that widespread showers and thunderstorms are expected Tuesday, with the shortwave energy traversing the area.
For today, some thunderstorms are forecasted, but severe weather is not expected as convective parameters appear weak. The forecast discusses CAPE values hovering around 1000 J/kg and limited shear, which may result in the storms having a tough time getting going. When looking at the high temperatures peaking in the mid-90s, one has to wonder if the heat itself won't be the most notable discomfort for area residents today. As we head into Tuesday, a sharpening trough deepens and a frontal boundary is likely to push through, potentially increasing the coverage of storms, as mentioned in the forecast discussion from the National Weather Service.
Midweek, the thermometer is expected to climb even higher on Wednesday, with the trough moving east and surface high pressure off the coast. The question remains whether a front will linger, possibly serving as a focal point for more thunderstorms during the afternoon and evening hours, especially in the southern and eastern parts of the region.
The marine forecast indicates Small Craft Advisory conditions through Tuesday morning for the Chesapeake Bay, likely to be extended into Wednesday. Mariners should remain cautious for storms, particularly on Tuesday. Minor coastal flooding is a possibility this week in spots like Annapolis due to the rising water levels carried by strengthening southerly winds.
