Friday Night : Variably cloudy, very warm and muggy. Low in the upper 60s.

The heat is here, and that was evident on Thursday, as Poughkeepsie hit a high of 87°… but the humidity was low, so it was a very comfortable… summer-like day.
Friday will see some differences across the Hudson Valley, primarily the rapid increase of humidity. Dew points will rise quickly on Friday, and that will drive humidity levels up. Friday’s going to be a muggy, sticky day across the Hudson Valley. We could see a spotty afternoon thunderstorm, but the majority of the area stays dry. Friday night, the humidity holds on… and a warm, steamy, muggy night is ahead… so you’ll want to keep those A/C units ready.
Saturday is a very busy day for many across the Hudson Valley. We’ve had many questions about the timing of the thunderstorm threat, so lets take a closer look. The heat and humidity will be high on Saturday, with temperatures approaching 90° in places, and with the humidity… it will feel even hotter. But relief is on the way, because a powerful cold front is on the way toward the Hudson Valley. Along with it, will come the risk of showers and thunderstorms. The exact timing is a little tricky, but it appears that the storms will reach the region between 2pm and 6pm. (Updated 10am Friday… The SPC office has the Hudson Valley in a “Slight Risk” for severe thunderstorms on Saturday now… so while it doesn’t look like a widespread severe weather event, we will definitely need to keep an eye on this event as it unfolds Saturday afternoon, as a few thunderstorms could become severe.)
The simulated radar image above paints the picture. It appears that a good bit of the region (circled in black) will see scattered thunderstorms (roughly 60% of the area). The NAM model has the activity really picking up around 5pm… but to get the best idea possible, we’ll take another look again at the timing and intensity of the storm threat, in the Friday evening update. Not everyone will see a storm… but there is a pretty good chance that between 2pm and 6pm on Saturday will see some rough weather. Behind the front… Sunday looks great, if not a little cool, with very comfortable humidity levels. That could lead us to a couple cool days to kick off next week… but more on that as we get closer.
I’m going to try and get some sleep, but we will be watching Saturday’s forecast closely… as so many people have plans for this weekend. If you’re one of the readers who have plans for Saturday, take solace in the fact that I’m personally invested as well. I’m having my driveway sealed early Saturday morning… and the project manager said that as long as we have 3 hours of dry weather after it’s done… the seal will take hold, and the driveway will be great. So you best believe, I’m watching this closely… because that is not a project I want to have to do 2 times. Off to get some sleep… I’ll see you Friday night, and in the mean time… have a great Friday! TGIF!.
