Worst Storms Were In Central New York/New England; Unknown If Tornadoes

Radar image of a dangerous storm heading into southwestern Vermont
last evening. Where the blue line and arrow is drawn in, the apex
of the backward "C' shape likely had damaging straight line
winds.  The red box was a tornado warning as radar
detected some spinning in the northern part of this storm. 

The severe weather in the Northeast materialized pretty much as expected yesterday, cutting a swath through western and central New York and finally through central New England.

A tornado watch was in effect for this event, and some of the storms were definitely rotating. However, it's unknown whether any tornadoes touched down.

 I'm sure National Weather Service offices in Albany, New York and in Massachusetts and New Hampshire will look into this.

The most interesting and dangerous cluster of storms got going north of Utica, New York. It promptly triggered a tornado warning.  A house in the path of this tornado warning lost its roof in the storm, but it's unclear if it was a twister or straight line winds.

The storm continued to cause damage, and occasional tornado warnings as it moved eastward into Saratoga, Washington and Warren counties of New York, just west of the Vermont border.  There were a lot of trees down, some damaged houses and roads blocked by debris. At least 36,000 people lost power in that area, according to the Glens Falls Post Star. 

The Post Star posted a photo of what they said was a tornado in Wilton, New York, but I'm not convinced by the photo. It could also be a downburst or a hail shaft, in my opinion.

The Glens Falls Post Star displayed this photo taken by Adam Colver
of what they said is a possible tornado in Wilton, New York. (Behind
the red brick part of the building). This feature in the storm could
also be a shaft of falling hail or a microburst. 

The line of storms then moved through Bennington and Windham counties, triggering tornado warnings around Sunderland, in southwestern Vermont, and the Brattleboro/Dummerston area in the southeast.

Again, it's unclear whether there were any actual tornadoes. The rotation on radar images in this storm did not look particularly intense. But this area is pretty distant from radar sites, so the quality of the storm images wasn't great.

There were reports of trees and wires down along the path of this storm and particularly where the tornado warnings went off. But this damage could easily have been caused by straight line winds and not anything tornadic.  If it was a tornado (which I kind of doubt) it would have been a fairly weak one.

The cluster of storms moved on into southwestern New Hampshire. I think slightly flatter ground there helped the storm intensify, and damage to trees and even buildings was greater than in Vermont.

On the southern end of this cluster of storms, high winds tore the roof off an apartment building in Holyoke, Massachusetts, displacing about 140 people. Again, it could have been straight line winds. I imagine weather experts will examine the damage in Holyoke to determine what caused it.

Further north in Vermont, there were strong to severe storms from about Middlebury to Montpelier to Bradford and points south, exactly as forecasters expected. There were reports of some trees and wires down with these storms. The storms in central Vermont were not tornadic. No tornado warnings were issued for this area, and there is no evidence of any kind of spin up that I could see.

Further north, in the quote, unquote more stable air, the parent storm system created a pretty good punch.  The line of heavy downpours, with some embedded thunder, managed to produce a wind gust to 47 mph in South Burlington. That's not severe, but still was kind of impressive.

The same storm system did more good than harm around my area in St. Albans, Vermont.  I got 0.88 inches of rain, with most of it coming within an hour during gusty showers.  We needed the rain, so I'm grateful that came through.

There's no severe storms in the forecasts now, but the predictions are pretty uncertain as to what will happen with our weather over the next few days.

A storm system will set up and sort of sit and spin over the central Appalachians over the next few days.  An early season subtropical storm seems to be forming off the coast of Florida and will get absorbed by that sitting and spinning storm

Meanwhile, fair weather high pressure will want to sink into northern New England from Quebec.  This will want to clear the skies over us.  So which wins? The rain to the south or the fair weather tothe north? Hard to tell, but as it looks now, we might get a period of rain Monday, then things will start clear out for the rest of next week. No promises, though.

Also, don't worry about any new outbreaks of late season chill if the Canadian high pressure system wins. Yes, it is from Canada, but it's not a cold batch of air.  Also, this fair weather system is, or will be, sitting over southern Quebec.

That's far enough south so that the warm May sun will keep raising the temperatures within this zone of fair weather, The upshot for us is we'll get near normal,  to perhaps slightly above normal temperatures by the end of the upcoming week.
