A Cold, Damp Vermont Sunday, And A Cool Autumnal Week

Today's rainfall prediction map from the National 
Weather Service in South Burlington. Though it
will be a rainy day, we ultimately won't get all that
much. The driest part of the state, the Northeast
Kingdom, will unfortunately see the least
 Saturday in Vermont felt like mid-October, with crisp air and bright blue skies, at least in  northern Vermont.

 High clouds were already starting to increase in southern Vermont. Those clouds were a sign of a very chilly Sunday coming in. 

The clouds were in place over Vermont as dawn broke today and rain was spreading in. Light rain should fall all day, though eastern Vermont should see mostly dry weather until mid to late morning. 

All this should hold daytime temperatures down in the 50s. As noted yesterday, this will be the coldest September 20 high temperatures since 1990, when the high was 53. 

The coldest high temperature on this date was 50 degrees in 1962  (The year 1962 was among the coldest on record in Vermont, as measured in Burlington). 

If it's going to rain, you want it to be beneficial, a real soaker. Unfortunately that won't be the case. Instead, it will mostly be annoying light rain, drizzle and sprinkles.  The rain might pick up at times to briefly feel drenching, but it won't be really make everything sopping wet. 

Only a thin top layer of the ground will get wet. There won't be enough rain to soak deeper. The Northeast Kingdom most needs the rain the most, and they'll get the least.

Some places in the NEK will receive less than a quarter inch of rain. Most of the state will see a modest quarter to a half inch. A few places in the far south could get a little more than a half inch

We're setting ourselves up for a cool week, too. Daytime highs won't be as cold as today, but we'll have to watch the nights for the risk of frost in a few spots. .

MONDAY

It will probably take its time clearing up during the day. Overall, most of us will have a mostly cloudy day, with more sun maybe in the Connecticut River valley. With cool north breezes blowing, it'll stay cool, with highs within a few degrees either side of 60.

 Some clearing Monday night will send temperatures down into the 35 to 42 degree range for most of us. Colder valleys could have some frost. 

REST OF THE WEEK

Massive, cool high pressure will set up to our north in Quebec, while low pressure is stuck in the Mid-Atlantic states or just offshore. This should keep us dry and chilly through the week. Some models take the Mid-Atlantic storm, or at least some of its moisture our way towards the end of the week. That's tossup right now, so we'll have to see how that plays out. 

Chances are, unfortunately, that we get little rain from that storm. But, we shall see!
