A slow-moving cold front is sliding south across the Baltimore-Washington region this morning. Winds are turning north. That should pull in slightly cooler and less sticky air through the day.
Most of the area stays dry. Highs still reach the 80s at lower elevations under a mix of sun and clouds. Dew points should drop from the lower 70s this morning into the 60s later this afternoon. Isolated showers are possible farther north, but coverage should stay thin.
It is already warmer and stickier than Wednesday. Early this morning, temperatures sit in the mid 60s to low 70s. Dew points are mostly in the 60s. Clouds have built along and east of I-95. Isolated showers may brush western Maryland around daybreak, but most of the region starts dry.
Highs today reach the mid 80s to low 90s. Humidity stays up. Showers and thunderstorms should fire first over the Alleghenies and then slide toward the I-95 corridor between about 4 and 9 p.m. The chance of severe weather is low. A few stronger storms could still produce brief gusty winds. Storms should fade a couple of hours after dark.
Canadian high pressure still covers the Baltimore-Washington region, but it has edged closer to the coast. That opens the door to a warmer day than early in the week.
Early morning temperatures are mostly in the upper 50s to low 60s, with mid-60s near Washington, Baltimore, and spots along the I-95 corridor and the bay. Skies are mostly clear. A little patchy fog is possible in mountain valleys and low spots before sunrise.
