Humidity. Remember humidity?
Alas, the honeymoon is over. After a long, sunny, mild and dry spring, Marylanders seem to be feeling the first truly muggy weather of the season. Warm, moist, tropical air is surging northward from the Gulf of Mexico ahead of a cold front approaching from the west. Dew points have risen from the mid-30s yesterday to the mid-60s today and climbing. The moisture in the air meant fog earlier today, and now thick, cloudy skies.
Behind it all there lies the cold front, which will move through the region later today behind showers and thunderstorms, perhaps some severe ones with locally strong gusty winds and hail. The front has caused some heartache in the Midwest.
After that, we're golden. We should shake free of the storms sometime tomorrow, and the long weekend looks great. Temperatures in the 70s and 80s, and sunshine. And drier air.
