The hazy, hot, and humid weather conditions that really only last two days, Tuesday and yesterday, will come to a very wet end today as showers and thunderstorms move through the region through this afternoon. Then our friendly marine air mass returns just in time for the weekend.
A cold front and wave of low pressure will move through the region through this afternoon with waves of showers and thunderstorms. Although most thunderstorms will not be severe, the strongest thunderstorms will be capable of wind gusts over 50 mph, frequent lightning, heavy downpours, and hail.
