6 PM Update
Storms have diminished and are pushing offshore. A drying breeze will reveal a beautiful waxing gibbous 'Strawberry' Moon tonight. Becoming much less humid. For a beautiful Monday. Tom Cheevers in Hull has some cleaning up to do as the grill is spared damage from severe storms today.This is Tom's Account of what happened:
I was sitting in the middle of (what neighbors are hearing to be a 75mph wind) tornado on Atlantic Ave in Hull. At first it didn't phase us and we continued to eat dinner. Once trees and power lines went down, shingles went flying, and the rain pounded, we retreated to the house. It was crazy...but wicked cool!

Back to previous post:
The web cam on top of Wildcat Mountain shows cumulus are bubbling up quickly around the summit of Mount Washington today. Did you hear about the race up Mount Washington yesterday, yup.. 1,000 thousand runners up the 7 mile auto road, the winner did it in just over an hour. Click here for race and Mt. Washington cams.
Today all the Dads in the race, and throughout New England, get a Weather Treat. The Treat? Why.. Warm Sunshine and Cloud Watching of course. I saw AltoCumulus Castellanus (ACC) at sunrise this morning. You know what that means? As Dr Gannon taught us (me, Weir Lundstedt, Tony Petrarca, Russ Murly, Jim Cantore, and 100s more) at Lyndon State College, ACC is the thunderstorm signal, indicating moisture and instability at mid levels of the atmoshpere. If the proper triggering mechanism is in place, we get thunder. Today we have low pressure in Northern Maine, with a prefrontal trough and a cold front, all great lifting mechanisms. We are also hot and humid with temperatures near 90 and dewpoint near 70. This all adds up to severe storms this afternoon. The storms should form a broken line form Eastern Maine to Eastern Connecticut by 2 PM. Then pushing offshore by 6 PM, in time for the Red Sox to gain a sweep of the Dodgers in tonight's 8 PM start. Use this link to monitor severe warnings. Track the storms using our radar, Red is Thunder, Purple is severe. Damage should not be widespread, but a few storms will have gusts to 55 mph, with hail to one inch in diameter. Much less humid air and sunshine is here Monday. Then cooler air with cloud and showers late Tuesday into Wednesday. The pattern is setting up for frequent storms into early summer. The western trough, with cold in in northern Canada and persistent troughing in the Northwest Atlantic keeps our weather dynamic, and Midwest weather severe. The Gulf of Mexico is about 4 degrees warmer than normal, contributing to all the flooding in OK and AR, these storms show no sign of letting up. Soon we will be tracking named storms.
