August In May: 90 Degree Vermont Heat, Subtropical Storm, Western Wildfires

pre-season tropical system in the Atlantic

 Typically in August, we get bouts of near 90 degree heat here in Vermont.  August is also the time of year we keep a close eye on the tropics for potential tropical storms and hurricanes. Late summer is also when wildfires really start to blossom out West.  

All this is happening now, which is really weird for this time of year. Welcome to August in May. 

Here in Vermont, Burlington reached 90 degrees Friday for the second day in a row. It wasn't quite a record high, but still impressive for this time of year. 

Montpelier did manage a record high for the date on Friday. It got up to 89 degrees, besting the old record of 86 degrees set in 1977.

It'll be quite warm again today, but not quite as toasty as the past two days.  There's increased cloud cover, so that will hold temperatures down a bit.  

Still, most of us should make it into the 80s this afternoon. There will be a few hit and miss showers and rumbles of thunder today, but most of us will stay dry. 

A pretty strong cold front tomorrow will flush out the hot air and return us to seasonable conditions for a couple days anyway. A small percentage of Sunday's storms might reach severe limits with gusty winds, especially in southern and eastern Vermont, and over in New Hampshire, Maine and southern New England. 

More heat might briefly return to Vermont midweek.

But our August in May theme goes on elsewhere. The official tropical storm and hurricane season doesn't begin until June 1, but there's already a subtropical storm out there. 

Subtropical Storm Ana formed overnight northeast of Bermuda.  It's considered subtropical because it has characteristics of both a tropical storm and a regular old storm. Still, a subtropical storm is unusual in May.

Less unusual than in the past, though.  Every once in while, a tropical or subtropical storm would form in the Atlantic, but it was rare.  But with Ana forming overnight, this is now the seventh consecutive year a tropical or subtropical storm has formed in May over the Atlantic.

This particular subtropical storm is no real threat.  It won't strengthen much beyond its current 45 mph top winds, and should dissipate in the next couple of days. 

Another system that threatened to form into another tropical storm overnight in the Gulf of Mexico failed to get its act together. Still, this wannabe system will spread unwanted, heavy downpours into flooded eastern Texas.

Flooding sure isn't the problem out West.  As of earlier this month, 18 square miles of California had already burned so far this year.  That's ahead of the pace of last year, which turned out to be the worst wildfire season in that state's history. 

Multiple wildfires have already broken out in Arizona, well before the peak of their usual fire season. 

All of this strange May weather I described above might be the main feature, and not bugs of the rest of the summer and early fall. 

Long range forecasts are often unreliable but for what it's worth, the Climate Prediction Center forecasts a hotter than normal summer for most of the United States, including here in Vermont and the rest of New England. 

Also, most experts expect a busier than normal 2021 Atlantic hurricane season, though it won't be as extreme and hectic as the record season last year.

And, with drought widespread across the western third of the United States, the wildfire season out there is sure to be a humdinger, perhaps on par with last year's devastating season. 

The month of May doesn't always hold clues as to what the rest of the summer will bring, but warning signs do seem to be flashing toward a very interesting summer in the weather department.
