Coolish Stretch Of June Weather In Vermont/New England Will End Soon

Vermont had weather winners and losers once again
on Saturday. In this satellite photo taken in the
early afternoon, it was clear near the Canadian border
while the rest of northern Vermont had a mix of
sun and puffy clouds, But southern Vermont was
socked in by the clouds once again, as so often
has been the case lately on Saturdays.
 In recent years, we've had some awful spells of rather intense early season heat and humidity in May and the first half of June in Vermont. 

Summers have been starting earlier than they used to, in large part due to climate change.   

This year so far has been more temperate. It did make it to 90 degrees in Burlington, Vermont on June 5, but spells of very warm, humid weather have been brief.

That might be about to change. Warm, very humid air looks like it will flow into northern New England by mid-week. 

After that, there might be a brief cooldown or two, but the overall weather pattern is trending toward warmer, more summery conditions.

THIS WEEKEND

It was a tale of two Vermonts again on Saturday. After some early morning sprinkles, it was gorgeous across northern parts of the state yesterday. We had sunshine, deep blue skies finally free of the smoky haze, a few puffy clouds to decorate the skies and comfortable temperatures in the low 70s.

Meanwhile, southern Vermont was socked in with the clouds most of the day.

Today will be a little more fair to everyone. It'll be partly sunny almost statewide  -- the clouds will sort of be in and out all day -  and there's the slightest chance of a brief shower. But the vast majority of us will stay dry.

An exception would be far southern Vermont, near the Massachusetts border, They're closer to a stalled weather front that's been stuck in the Mid-Atlantic States for days. So clouds will probably dominate out of today in place like Bennington and Brattleboro.

Then changes are afoot

THIS WEEK AND BEYOND

You'll notice the humidity rising day by day early this week from pretty low levels today to really sticky by Wednesday and Thursday.

The dew point is a good indicator of how icky it feels out there. Today, those dew points will be in the 50s, which is comfortable. On Monday, they'll edge closer to 60.  That's still OK, but you'll notice it a little if you're really exerting yourself outdoors. 

Tuesday's dew points will be in the low 60s, which is a little sticky, then in the upper 60s Wednesday and Thursday. There's your ick factor right there. 

Actual daily temperatures will climb, too, from the lows 70s today, upper 70s Monday, near 80 Tuesday and in the 80s Wednesday and Thursday. 

When you combine such warmth and humidity, you often get showers and thunderstorms. At this point, those seem a safe bet Wednesday and Thursday. It's a little too soon to tell, however, if any of those storms would get on the strong side. It's also a little early to figure out if any of those storms will dump a bit too much rain. 

Those details will be ironed in the coming days. 

Forecasts beyond this coming Thursday are a little more questionable, only because a lot can change in the atmosphere over four or five days. Those changes sometimes throw longer range forecasts way off.

But an early guess suggests a brief cooldown coming next weekend (down to near normal mid and upper 70s).  Then, some computer models bring in an even hotter few days right after next weekend. We could have a spell of 90 degree weather in a little over a week from now.

Summer seems to be here, folks.
