It is hard to believe that we are halfway through the month of July! So far, 1.73" of rain was measured at BWI this month. We are already flirting with the average value of 1.77" for the entire month of July. There is still plenty of time to match/exceed the normal value. The flowers will be happy to hear that there is rain on the horizon. There is also the chance for thunderstorms as well.
A trailing cold front will be moving through the Great Lakes region on Thursday with scattered showers and thunderstorms ahead of it. The Storm Prediction Center has placed northwestern parts of Maryland under a Marginal Risk (level 1/5) as areas in Western Maryland have the better chance to see strong to severe thunderstorms. Shower and thunderstorm chances look to diminish as the energy moves eastward near the Baltimore metro. Therefore, computer models are showing higher rainfall amounts focused to the west of BWI through Thursday. There will be multiple windows for showers and storms Friday as the cold front swings through Maryland. We also have shower and thunderstorm chances for the upcoming weekend. Keep the rain gear handy!
