There's yet another 90-plus day ahead for Central Maryland, with dew points still in the sultry low 70s. It was already 87 degrees downtown by 10 a.m. But this sticky, suffocating day should be the last for a while. There's a cold front pressing in from the north and west, with a batch of cool, dry, Canadian air behind it. Here's AccuWeather's take.

Forecasters are looking for a high of 94 degrees this afternoon - the 10th day in the 90s so far this year. The overnight low at BWI-Marshall was 73 degrees, but downtown residents were hotter. Our sensors here at Calvert & Centre streets recorded a low of 79 degrees - for an hour. The rest of the night the air here remained in the 80s.

By dinnertime, the approaching cold front will begin to lift this warm, humid air mass and wring it out. That means thunderstorms. The storms could continue overnight and into Friday before the front clears the region early tomorrow. Here's the radar loop.

On Friday, we'll really feel the relief, as daytime highs stall in the upper 70s across the state, and readings sink in to the 60s overnight. And the weekend looks beautiful, with highs in the low 80s and sunny skies. Headed for the beach? Here's the cool forecast. 

Whatever rain we pick up will be more than welcome. The new Drought Monitor map is out today, and it shows that Western Maryland - 20 percent of the state - has slipped from "abnormally dry" to "Moderate Drought" since the previous week. Nearly the entire state - 98 percent - is rated at least abnormally dry. That's up from zero percent on April 3.

Here's the six-week animation of the maps.
