The summer solstice isn't until Friday but we should have summer-like weather today and tomorrow. The city is on the warm side of a stationary front that's just now dropping down into the state from Ontario. Before that front causes any hanky-panky we should have a mostly sunny day with highs in the mid 80s. Spots away from the ocean, like interior New Jersey and Connecticut and the Hudson Valley, are at risk of a thunderstorm this afternoon, but the cool waters surrounding the city will put a damper on that convective activity.
Assuming those thunderstorms do develop, they may drift into the city this evening. These are solar-powered storms so they'll rapidly lose strength as sunset nears. As the stationary front slowly moves southward there will be another chance of showers and thunderstorms tomorrow. After last Friday's rain we are only two-thirds of an inch away from becoming the rainiest June ever, so if a thunderstorm develops tomorrow let's hope it is a good one. Tuesday's high will be somewhere between the upper 70s and mid 80s.
Sometime on Tuesday night a cold front is expected cross the region and push all the humidity far, far away. Wednesday is looking like the coolest day of the week with a high in the mid 70s. Unless you believe the Weather Channel, which thinks Thursday will be slightly cooler. Let's ignore them and go for highs near 80, and mostly sunny skies, for Thursday through the weekend.
