Every day in the first week of June was colder than normal, but that is about to change as the jet stream lifts northward for an extended period of time. For that to happen though we have to first deal with some potentially hazardous weather. The high pressure system that brought the beautiful weather this weekend has moved off the coast and the resulting southerly breeze will allow the humidity to climb throughout the day today. That's going to bring us mostly cloudy skies and an afternoon high in the upper 70s.
The increased humidity comes into play tonight as a cold front draws near. First, disturbances ahead of the front, and then the front itself, will start pulling and pushing the warm, moist air upwards. That's a recipe for showers and thunderstorms. The storms could start as early as this evening but are more likely after midnight. Some of the thunderstorms could produce heavy rain, small hail, gusty winds and lots of lightning. After a quiet morning tomorrow, we'll face another round of afternoon and evening showers and thunderstorms. Tuesday's high should reach the lower 80s.
Skies will begin to clear once the cold front passes late Tuesday night. Wednesday is expected to be sunny and warm with a high in the lower 80s. We have a chance of getting our first 90 degree day of the year on Thursday, but we'll probably have to settle for the upper 80s. Highs in the 80s will be the rule through at least Saturday with our next chance of thunderstorms happening as the weekend begins.
