MORE HUMIDITY
Unfortunately, all good things must come to an end. By Friday, humidity will start to surge back, making for a sticky weekend. This will also start our typical pattern of morning clouds and afternoon sunshine.

RAIN CHANCES
At this point, the weekend looks dry, as a stout cap on the atmosphere will keep storms from developing. A pattern change early next week should change that. Look for storms to flare up Sunday night through Tuesday in our area. We donβt have enough data yet to say when or where, but with it being spring, these storms could be strong. More updates to come!
