Above is the Day 2 convective outlook issued by the Storm Prediction Center. You see here in CNY we're in the slight risk area for Tuesday. If you click on the image, you'll get the actual outlook. It'll be updated again this afternoon.
Obviously we're got the heat in place. Southwest winds will push temperatures once again near 90 Tuesday, and we'll also likely see a spike in dewpoints tomorrow. That'll provide us with more than enough ingredients for thunderstorms. We'll also have a pre-frontal trough coming through during the peak of daytime heating, and also some help from the jet stream winds aloft. The winds are forecast to be quite brisk Tuesday afternoon, so any storms that get going will be able to tap into that energy and could produce damaging wind gusts in excess of 58 mph. The time for these storms would be after 12 PM, so get out early in the day if you need to get outdoor work done.
A cold front is forecast to arrive in Central New York around sunset, and that may have another batch of showers and thunderstorms with it. Behind the front, much cooler and drier air will move in for Wednesday. Temperatures on Wednesday will be in the upper 70s to near 80, with humidity levels much, much lower. A disturbance in the jet stream may kick off a few fair weather clouds Wednesday afternoon, and there may even be a shower over the Adirondacks. Temperatures will begin warming through the rest of the week, with the humidity increasing during the day Friday.
