Potpourri: NH Tornado, Decent Rains, Quick Heat Squirt

Let's do some odds and ends today to catch our breath after several days of interesting weather

And more possibly interesting things to come. So here we go:  

NEW HAMPSHIRE TORNADO

To absolutely nobody's surprise, the National Weather Service office in Gray, Maine, confirmed a tornado on Monday in Charlestown and Claremont, New Hampshire 

That was the tornado I talked about yesterday that was caught on a truck dash cam. 

The National Weather Service said the tornado was an EF-1 with top winds of 90 mph.

It traveled 4.8 miles and had a maximum width of about 330 yards. It lasted only six minutes, touching down at 6:22 p.m. Monday. In that short time, it snapped or uprooted about 1,000 trees.  It looks like the tornado missed buildings, which is nice. A few houses suffered a little damage from falling trees in the area, but it's unclear if that damage was from the tornado or straight line winds.

The tornado did close Route 12 in Charlestown for several hours so crews could clear fallen trees and replace about 20 utility poles wrecked by the twister, says WMUR. 

The damage track traced by the National Weather Service/Gray confirmed the tornado stayed a little east of the Connecticut River through its entire life, meaning officially, no tornado in Vermont. 

DECENT RAINS FOR NOW

That long dry spell in Vermont from May 5 through 13 in Vermont had many of us wondering if this would be another kind of droughty summer, like the past two were. At least in northern Vermont. 

It turns out this month's dry spell didn't parch us out to the level we were at in 2020 and 2021. Soil moisture before the dry spell was good, so we had reserves. And the rains seem to have returned. 

Most place in Vermont got at least an inch of rain Saturday afternoon through Monday evening. Yesterday, some of the showers in northern and central Vermont deposited slightly more rain than I thought we'd get. I was surprised by the intensity of a downpour late last evening for instance. 

For the month so far, Burlington is only 0.17 inches below normal as of midnight. For the year as a whole, Burlington is about a half inch above normal for precipitation. Nothing extreme, but normal is good. 

More is on the way. Nothing excessive, but enough to keep the crops and gardens at least somewhat watered.

A disturbance should bring more light rain on Thursday. We'll have to watch out for Sunday.  The timing of a cold front is uncertain. It could be a bust, or we could receive strong thunderstorms with heavy downpours, or something in between. We'll have to wait and see. 

Long range forecasts through the end of the month indicate somewhat above normal precipitation around here, but note that long range forecasts are iffy.  Still, the next two weeks seems to want to feature a parade of modest rainfalls passing through. Of course we don't know what the rest of summer will bring

HEAT SQUIRT

Speaking of summer, it looks like we're in for another spell of hot summer weather, though this one will be brief. We're on a temperature roller coaster, as you've surely noticed we're off to a cool start today. 

After Thursday's chilly showers, we should pop up to 80 degrees on Friday, and stay warm and muggy Friday night. At this point, Saturday is looking it could be another day of near 90 degree temperatures. The record high in Burlington on Saturday is 92 degrees, so I don't think that record will be broken, but you never know. 

It'll cool down again after that cold front I mentioned for Sunday.
