Vermont Rainfall Disappointing; Humidity IS Going Down Though

Clouds from one of many little downpours that just 
missed my location in St. Albans, Vermont in this
humid weather in the past three days. The afternoon shower
in this pic produced a brief heavy downpour just two
or three miles to my south and east 
We kind of find ourselves in the same boat this morning as we did yesterday morning:

The humidity has eased in the northwest corner of Vermont but lives on elsewhere. 

As of 8 a.m.today, for instance, the actual temperature and dew point in Burlington were  63 degrees and 61 degrees. Not bad!

Montpelier, just down the road, was still stuck with a temperature of 76 degrees and a horrible dew point of 70 degrees.  Those terrible, muggy conditions continued elsewhere in central and southern Vermont. 

The good news is the heat and much of the humidity is finally going to get flushed out of the rest of Vermont during the day today. The bad news is that during this transition, rainfall was disappointing. 

The rainfall situation isn't great because we're about to launch into a pretty dry period that will probably last a week or more.

First, this morning's situation. That weather front that was stalled up north well into last night, and almost all the expected rain stayed up in Quebec.  The forecasts had actually called for a slight chance of local flooding in far northern Vermont, but that sure didn't happen! 

Rainfall totals that I've seen so far include less than 0.2 inches in Burlington and Plattsburgh, for instance. Montpelier managed to get bullseyed by an afternoon downpour Monday, so they managed to receive half an inch. Here in St. Albans, I managed to collect a somewhat respectable 0.6 inches of rain, which is OK. 

A small handful of places won the downpour sweepstakes, managing to get decent rains. Waitsfield reported 1.57 inches. 

In general, rainfall across Vermont was between 0.1 and 0.6 inches. 

Overall, I'm not impressed. 

After  kind of bouncing back and forth near the Canadian border through yesterday and most of last night, the cold front is finally getting a shove southward. It's still not moving very fast, so most of far southern Vermont is going to endure another nasty humid day. Though even there, you should begin to notice some change in the air late in the day.

Areas to the north can expect a cloudy day, maybe some sprinkles and patchy drizzle and fog. It'll still clammy, with dew points in the meh low 60s. Not exactly refreshing, but much better than it's been.

In the much more humid air to the south, the slow cold front looks like it will kick off some showers and thunderstorms. Some might have pretty good downpours, so you still have a shot of receiving some needed rain in some spots mostly south of Route 4. 

The humidity will stay moderate into Thursday, when a reinforcing cold front arrives. That will produce some hit and miss showers and storms, but again, nothing impressive.

But the air behind that Thursday front will be delightful.  Dew points will crash into the 50s, which for most of us is quite comfortable Friday through Sunday. Over the weekend, we'll have some chilly air aloft, which will help cumulus clouds bubble up.

So we'll call it partly cloudy. Probably mostly cloudy over the mountains and mostly sunny over Lake Champlain. The lake tends to squelch those bubbly cumulus clouds in this weather regime.

Beyond Sunday, the weather models seem to be all over the place, so I'm just not going to deal with it for now.
