More heat, humidity, and storms are on the way for the middle of the workweek. High temperatures once again Tuesday reached into the mid to upper 90s with feel like numbers over 100 degrees. This marks 46 days of 90 degrees or better in Baltimore with several weeks of Summer yet to go.

With all that heat and humidity numerous showers and storms blossomed Tuesday afternoon as a backdoor stationary boundary rolled into the area off an east southeasterly breeze. Storms though mainly stayed south and west of the area sparing Baltimore any rain which coincidentally has been a trend this year. Since July 1st we have only seen 22 of 50 days with measurable rain with our last 1"+ of rain at the airport observation site coming on March 21st of this year.

This may change Wednesday and Thursday though as our stationary boundary lifts back north back north allowing our powerful cold front which looks to flip the pattern late week to move in.

As the front moves in Wednesday the chances for storms increases. Coverage will be a little more widespread Wednesday and Thursday with low end risks for severe weather remaining in play. Any storm that we do see over the next two days will pack a punch with damaging winds, small hail, localized flooding, and lots of lightning concerns.

High temperatures will go from the 90s Wednesday and Thursday to the 70s come Friday as the front moves through. Cooler and comfortable air will wedge down the Blue Ridge making for excellent conditions with rain chances diminishing for the weekend ahead.

Speaking of a cool-down 8-14 day trends suggest normal to below normal conditions sticking around as we head toward the end of August. The question is will that pattern stick with a few more weeks of Summer to go. Fall is technically 33 days away so not so fast on the sweaters just yet!!
