Wednesday Morning Vermont Update: Drops Of Rain, But Little Drought Relief

A few sprinkles helped enhance the colors in the sky
over St. Albans, Vermont Tuesday evening. The 
showers only produced a trace of rain here. 
Tantalizing drops of rain have fallen here and there in Vermont over the past 24 hours, slightly wetting the ground in a few spots, but still doing almost nothing to relieve drought conditions.  

A very brief downpour blew through the Burlington area last evening, depositing 0.16 inches of rain. But that left Burlington easily among the wettest spot in Vermont Tuesday, which really isn't saying much. 

A little more rain is in the forecast which will keep the worsening drought slightly at bay, but there's still not much of a prospect of any super soaking rains soon.

A semi-decent area of showers was over parts of Addison and northwest Rutland counties as of 8 a.m. today. A few spot showers will continue today, especially in the southern half of Vermont, where a few lucky towns could get a little over a tenth of an inch of rain, while others say dry. Hit and miss again. 

Today should  be about as autumnal as yesterday, with highs within a few degrees either side of 70.

SLIGHTLY WET COLD FRONT

The cold front we've been talking about for the end of the week looks like it will graciously dampen Vermont a little, which is nice.  But once again, it will be a bit of a swing and a miss for heavier rains.

The last cold front this past Sunday and Monday was supposed to slow down and create extra rain over Vermont. Instead, most of that extra rain fell in northern New York and extreme northwest Vermont.

It looks like a somewhat similar rainfall pattern will strike again, with some key differences.  

The latest rain forecast from the National Weather 
Service. Only a quarter inch of rain is expected through
early Saturday in most places. 

It'll start off cool again tomorrow with dawn temperatures in the 40s for many of us. Some southwest breezes in the afternoon will bring temperatures into the mid-70s, which is just a smidge below normal,

Increasing clouds will promise rain but there's a catch. The approaching cold front will start out with great dynamics, dropping decent rains Thursday night in northern New York despite a "meh" moisture supply. 

Over in the St. Lawrence Valley, they could see a good 0.5 to 0,75 inches of rain Thursday night and Friday. 

As the front gets into Vermont Friday, it will start to weaken.  It will have enough oomph left to drop some rain, especially north, and that might even be a rumble or two of thunder. 

Expected rainfall amounts are subject to change, and the forecast could change a lot by the time we get to the event. 

But at this point it looks like rainfall with the actually front will only amount to a quarter inch, give or take. It'll be a little more to the northwest, where the northern Champlain Valley could see more than a third an inch with the front by Friday afternoon. The south and east loses again, with maybe a 0.1 to 0.2 inches.

After the cold front goes through, a chilly pool of air aloft - an upper level low - will probably basically sit and spin somewhere near the Vermont/Quebec border Friday night through Saturday night. 

That will keep light showers going over much of Vermont. They should be just inconsequential sprinkles in southern valleys, if that. More frequent light showers should hit central Vermont and the valleys of northern Vermont Friday night and Saturday, but they won't amount to all that much. 

The western slopes and ridgelines of the central and northern Green Mountains could get a decent dampening with this regime through Saturday. Those high elevation places could see a quarter inch of rain. 

Expect continued pre-fall weather Friday and Saturday as highs stay in the 60s, except lower 70s in warmer, sunnier southern valleys. 

BEYOND SATURDAY.

The dry times return after Saturday. There might be a few lingering sprinkles in the north and mountains Sunday. But that will be it for several days, as it looks now. Dry high pressure looks like it will stall nearby later Sunday through at least next Thursday morning. 

That'll bring low humidity, sunshine and somewhat of a warming trend, all bad news because that week of weather would dry out whatever meager rains we see through Saturday.
