Summer officially arrives at 7:09 p.m. This marks the time that the sun is at its highest in the sky, giving us the most time of sunlight that we will get all year long. And it’s going to feel like summer out there.
A heat advisory goes into effect for most of Maryland (excluding the Eastern Shore and Garrett County) at noon today. It will continue through 8 p.m. tomorrow for two hot days. We are forecasting a high of 96 degrees today and 98 degrees tomorrow. The record both days is 100 degrees, so we will be close but probably come up just shy. It will feel like it’s over 100, though, when you factor in that high humidity/dewpoints.
There is the chance for a late-day thunderstorm tomorrow, then a better chance for scattered thunderstorms on Friday as a cold front swings through the state. Any lingering showers will move out by early Saturday. This front will knock highs back to the upper 80s – not as high as the middle of the week, but still above average. Even cooler air will move our way the middle of next week, behind a second storm.
The tropics are heating up. Tropical Storm Chris was born way out in the Atlantic yesterday. It may gain strength, but will stay very far away from the United States. In the western Caribbean, there is another area of disturbed weather being monitored for development. This one could move into the Gulf and gain strength. The next name on the list is Debby.
