Monday Evening Storm Update, Vermont and Northeast

I've been watching an interesting little thunderstorm for the past two hours that kept redeveloping south of Plattsburgh, then moving northeast toward St. Albans and falling apart, only to reform near Plattsburgh and repeat the process over and over.
A narrow, slow moving, but torrential thunderstorm
is seen looking southwest from St. Albans as
the storm stalled moved slowly just south and east
of Plattsburgh late this afternoon. 

I'm sure there are some small areas under the heaviest part of that storm that have received upwards of an inch of rain. Meanwhile, just sprinkles in St. Albans.  That stalled storm has finally fallen apart

It's been that kind of day, as expected. Some areas got blitzed by heavy rain, others got practically nothing. I hate to say I told you so, but I told you so in this morning's update.

The action's not over. The cold front approaching us has triggered a line of strong to severe storms in northern New York as of a little before six p.m.

There's a severe thunderstorm watch for the northern portion of the Empire State all the way east to Lake Champlain until 10 a.m.

I wouldn't be surprised if that line of storms causes isolated areas of severe storms in northwestern Vermont later this evening, too.

It's still wicked humid out there, so any storms this evening still can drop a tremendous amount of rain in a short period of time.  I'm guessing some towns in northern New York and northern New England could see some street flooding, rapid rises along creeks, washed out driveways and some big puddles.

The flood threat in northwestern New England isn't as high as it is at points south and east. Parts of southern New England have had more than six inches of rain since Saturday, and more rain will cause problems there this evening. There's already some flash flood warnings up for that part of the country.

The long-advertised cooler, drier air won't come blasting in tomorrow as strongly as first thought, but it will be notably more comfortable out there Tuesday, amid the risk of a few lingering pretty light showers.

They've also backed off a bit on the strength of the cool spell toward the end of this week, with fewer places expected frost Thursday night that earlier thought. But it will still feel like fall later this week into the first part of next week.
