Good Friday -
Hot temperatures have been scorching about half of the lower 48 this week. We have gotten relief in the Northeast as a frontal boundary has been settled in our south. Record-breaking heat and plenty of 100s have been showing up on the weather maps as of late in Illinois, Indiana, Missouri, Arkansas, Tennessee, Kentucky....need I go on?
This is the latest weather alert map from the National Weather Service which has about 25 states under some kind of heat advisory, excessive heat watch, or excessive heat warning. As you can see in this image, northern New England is not under any such alert.
However we will get a taste of it. We at the SkyTracker weather center expect temperatures to rise to about 90 degrees in the warmest locations along the Champlain, St. Lawrence, and Connecticut River Valleys. Elsewhere widespread 80s are expected. It will even feel a bit muggy, but not terribly oppressive at all.
But come late this weekend and into early next week, we'll get a cool down! I haven't written much lately regarding cool weather coming in, but temperatures will be about five to ten degrees below average for daytime and nighttime readings, Monday and Tuesday especially. In fact, only 11 of the last 30 days in Burlington have been below average in terms of temperatures. If that doesn't sound too impressive, we'll have to take a look at the warmer days. That's because when it has been warmer this past month, it has been beating the averages by 10° frequently. A running average in the last 30 days shows Burlington warmer than average by roughly 2°F.
On another subject, the National Weather Service confirmed straight-line wind damage in Cabot/Walden Vermont associated with a wet microburst Wednesday, July 4th. This was a big thunderstorm that dumped up to two inches of rain in less than an hour, produced one inch diameter hail, but most noticeably took down dozens of trees. The National Weather Service in Burlington estimates winds gusted to 70-85 mph in a straight, but divergent path outward from the storm. You can think of it this way: Cooler and wet air descending down from the thunderstorm in a very fast motion and hitting the ground. While it wasn't a tornado, it did as much damage as a very weak EF 0 tornado.
