What a perfect day! We had sunshine, low humidity, and seasonable temperatures. The weather looks good for any outdoor grilling or fireworks tonight as we watch just an increase in some mid to high level clouds. Temperatures will drop into the upper 70s after sunset, eventually bottoming out in the upper 60s by morning.
Tuesday will start off comfortable, but humidity ramps up quickly by the afternoon. At the same time, an area of low pressure will dive out of the Great Lakes, and provide us with an opportunity for storms. If the storms come earlier in the day, the severe threat will be lessened, but if storms hold off until mid to late afternoon, ingredients will be there for a few storms to go severe. The main threat is damaging wind gusts but with some enhanced wind shear along the nearby warm front, an isolated tornado is also possible.
A second round of showers or storms is possible late Tuesday night into very early Wednesday morning, but the confidence in that is lower. A few additional storms will pop Wednesday afternoon as a front stays nearby but most of the day will be dry. Humidity will remain elevated though with dew points closer to 70.
We’ll see similar conditions Thursday as a storm or two could pop south of Harrisburg. A better chance for storms will come Friday as the next cold front approaches. Behind this front, dry and less humid weather awaits us for next weekend!
