A cool front passed through the region on Sunday and the new work week will start with comfortable temperatures and humidity levels as yet another Canadian-born high pressure system heads our way. The high will quickly shift off the coast on Tuesday and this will open the door for hot and humid conditions to move back into the Mid-Atlantic region for the period of Tuesday, Wednesday and Thursday. A strong cool front will then pass through the region on Thursday bringing with it the chance for strong thunderstorms, and then another cool air mass will follow for Friday and Saturday. In fact, this next cool air mass will likely be the coolest yet this season with highs on Saturday struggling to escape the lower 70's.
Elsewhere, Tropical Storm Humberto has formed in the eastern Atlantic. It has a chance to become a hurricane within the next 48 hours or so. If this happens, it would be the first hurricane of the season which is very late for that to occur. In fact, if Humberto does not reach hurricane status by Thursday then this would be the latest start to a tropical season without a hurricane in the satellite era (since mid 1960's).
