High pressure to our north will provide pleasant weather today, with highs in the mid to upper 70s.

The high will shift off of the coast later today, shifting our winds to more southerly and pumping in warmer and more humid air. Highs tomorrow will be around 90 degrees.

Wednesday will be hot and muggy. Expect highs in the low 90s under partly sunny skies.

A cold front will approach and move through on Thursday. Temperatures will rise to near 90 degrees by the afternoon. This, combined with the approaching front, will set off scattered showers and thunderstorms into Thursday evening.

High pressure will move overhead today and bring the hottest conditions of the week. Highs will likely top out in the mid to upper 90s with higher humidity values making it feel over 105. A Heat Advisory is in effect central Maryland through this evening.

Afternoon thunderstorms will likely develop over the mountains and move eastward towards the Baltimore/Washington metro during the late afternoon hours. This activity is expected to be isolated but areas that do see storms could see brief heavy rainfall and gusty winds.

Tomorrow will be similar to today, possibly a few degrees cooler with a slight chance of afternoon storms. Highs will be in the mid 90s with dewpoints in the low to mid 70s and heat indices near 105.

With high pressure remaining to our west, hot and humid conditions will persist along the east coast today. Highs will be in the mid 90s with heat indices around 100. Isolated thunderstorms will be possible again, mainly in the mountains.

The high will move overhead tomorrow, as it begins to be dislodged by a cold front. Highs will be in the mid 90s with a slight chance of afternoon storms.

The high will move to our southeast on Friday, allowing southerly flow to develop which may in turn raise our temperatures to the upper 90s and cause dewpoints to rise into the low to mid 70s. The result will be heat indices that may top 105 degrees in some areas. There is a slightly better chance of thunderstorms Friday afternoon.

Another Hot and Humid Day
