Friday Vermont Weather Update: The Humidity Keeps Wilting Us

An afternoon thunderstorm darkens the muggy Thursday
afternoon skies looking west from St. Albans. The 
humidity will more or less linger with continued
rain chances into the early week
Well, we survived the first day of our wilting humidity. 

On Thursday, it was actually a little hotter than expected in some areas. Burlington reached 91 degrees, as opposed to the forecast mid to upper 80s. 

It was the tenth time this year it's been 90 degrees.  And, it's the seventh year in a row in which we've had ten 90s in a year. That's unprecedented. Before this run, the most consecutive years with ten 90s was four, back in the 1940s.

OK, enough confusion with number. As expected, there were some showers and thunderstorms around. Burlington made out like a bandit with rainfall, as they received 0.64 inches.   A weakening, but still potent storm was responsible for much of that rain.  

The storm developed in the Adirondacks and blew up on the western shore of Lake Champlain. It looks like a lake breeze hit the storm, creating added lift in the atmosphere, That made the storm  blow up. Somebody on the New York shore probably got quite a storm, though I see no damage reported this morning.

The Burlington area was under a severe thunderstorm watch for a time. But once the storm passed the lake breeze, there was not enough general instability in the air to sustain it. It weakened on its way to and beyond Burlington. 

Elsewhere, while storms weren't severe, heavy rain was reported in parts of Addison County. Otherwise, the rain wasn't too widespread and those that receive rain had light amounts. Here in St. Albans, we picked up just 0.14 inches of rain. 

This morning, we wake to sticky conditions, as planned. Let's go through the daily forecasts to see how we'll get out of this muggy mess. Hint: We might have subtle ever-so-slight breaks in the humidity before the noticeably more comfortable air arrives next week

TODAY

Another awful day, but there are some nice aspects to it. For one, showers and storms are very unlikely because dry air high in the atmosphere will, squelch attempts at any development.

Even better, we might get a few hours of a semi-break from the humidity. During peak heating some of the dry air aloft might briefly mix down to the surface. So instead of dew points in the terrible 70 degree range, they might fall to the low 60s for a few hours. Still a bit humid, but not terrible.

However, the potential, slight lack in humidity, coupled with sunshine, means we'll get well into the 80s today. Once again, a few places could touch 90 degrees.

Tonight, showers will creep in as the humidity rises again. Definitely another uncomfortable sleeping night. 

SATURDAY

A weather disturbance early in the morning, before dawn, will keep showers and thunderstorms going.  Hit and miss generally. But on top of the icky air keeping you up, you might hear the roar of a downpour on the roof or thunder rumbling around before dawn. 

There might be a late morning break in the showers and storms, but they'll redevelop in the afternoon and evening. As usual, all the storms will be hit and miss. None of the storms will be severe, but some will produce torrential downpours. With all that water in the air, that has to happen.

We might see an isolated incidence or two of flash flooding, but the vast majority of us will be fine.  Most of us will see less than a half an inch of rain between now and Saturday night, though, again, a few spots will get much more and a few others will receive much less.

Amid all these rain showers and under mostly cloudy skies, temperatures should still make it up into the low to mid  80s. Which doesn't sound bad until you add in the dew points that will be near 70 degrees. Florida weather continues. I suggest a movie matinee. We're in peak summer blockbuster season, so get thee to an air conditioned cinema.

SUNDAY

We might eke out a decent day. Showers will tend to diminish in the morning, leaving us with just a chance of widely scattered showers and storms in the afternoon. As it looks now most  of us will stay dry and the sun should make an afternoon appearance. Highs should get into the 80s, with a slight drop in humidity. We'll take anything at this point.

MONDAY/TUESDAY

The humidity and shower chances will continue, but we'll be in the process of changing up the weather pattern. The mugginess might not be quite as bad as it's been, and highs should only reach maybe the upper 70s to low 80s. 

MID TO LATE WEEK

The weather will turn seasonable, the humidity levels should fall to completely reasonable levels. We'll still have shower chances as disturbance zip in from the west. Since the humidity will be lower, I'm so far not worried about any heavy rains from those systems.
