Strong storms expected into the night
The heat and humidity have combined to ignite a good deal of storms in the region as the day moves into the night. These storms will move slowly and drop a good deal of rain in the areas they overtake. Minor flooding issues will be possible, especially over the hilly terrain. The potential for any one of these storms to produce gusty winds and hail is also high so prepare your property for the storms. The Storm Prediction Center has upgraded northern Virginia into the Slight Risk Category as the rest of the Commonwealth will be in the Marginal Risk sector. Bottom line… isolated strong to severe storms today and into the evening.
Also, a very robust line of storms is migrating northwest to southeast over Illinois and Indiana today. Although expected to deteriorate as it pushes into the Appalachians, we may get some outflow tonight. Storms may linger a bit longer after sunset which has not been the case the past few days.
Spotty storms are possible again on Wednesday and we are still expected to reach the 90s. A front is expected to arrive late Thursday into Friday and cool us down for the weekend. There will be a good deal of rain associated with the front, but the timing is being challenged with each computer run. Current thinking is that the front will arrive late Thursday night into Friday meaning the rain will be widespread late Thursday evening and linger into Friday. My original thoughts had us clearing and cooler by Friday but the front seems to be a bit slower and we may see a cloudy and rainy Friday after all. I am still hopeful for the cloudy and cool weekend, but we may see a few showers off and on during that time frame.
Overall this is a very complicated forecast with timing and intensity being the toughest to nail down. The storms will be intense when they arrive so be prepared for that, but the threat of severe storms past today is lower as of our latest run.
