Big Cool Down Then a Possible Heat Wave?
This week our weather pattern will have a little bit of everything in it. We have a cold front that has already moved through the region Monday afternoon so now we are looking at cooler conditions for Tuesday.
There is an upper level low pressure system currently over New England that has rotated down.
Upper level lows are basically pockets of cooler air, or what we call a trough. That trough is going to send some cooler, drier air our way for Tuesday and Wednesday.
Also keep in mind the winds.
They will be quite breezy from Tuesday through Thursday.
Combine the winds with the very dry conditions and low humidity, this is where we get the enhanced threat for fires. Don't burn anything, check your burn piles that you have. The grass and trees dry out very quickly and can quickly turn into fuel for any little spark.
Tuesday's highs will only be in the 70s! Unfortunately this upper level low is not going to last too long and it will start to lift out for Wednesday, meaning warmer temperatures are going to return.
What's happening on the other side of the cool trough is a large ridge of High pressure over the Central Plains will push that trough out of the area, and that high pressure will move in. This means temperatures will really warm for Thursday and we could be talking about a heat wave for Friday into the weekend.
Plenty of hot and more humid air will be moving in. With that will also bring the chance for some pop up thunderstorms from Friday though the weekend.
Any relief in site? Well, possibly. There is a cold front that could swing through next Monday. At this point I don't think that's really going to bring us much relief.
Don't even ask about Debby yet, and if she will impact the Valley. Still way too early to tell.
