Hot Weather May Lead to Severe Weather Today, Rough Surf at Coast

Image
A strong cold front driven by a rather anomalous upper level low pressure system in Ontario will enable showers and thunderstorms to develop in the Northeast today.  Given high temperatures and dew points some of these storms will be severe with a primary threat of heavy rain and gusty winds.  Seasonable summer weather will follow Friday through the weekend.

General Overview/Short Term Forecast
This morning's surface analysis over the Northeast shows a stationary boundary over Maine and a cold front trailing through Ontario, Western NY and Western PA.
One can see this on the 7 am temperature map.  In downeast Maine temperatures are running in the upper 50's.  For Southern New England the majority of us are well into the mid to upper 70's.
Some showers and thunderstorms have already developed in New York.  These may hold together as they approach the Hudson River and Western New England.  In fact some high resolution short range guidance believes this not only holds togethe…

Severe Thunderstorm Watch Issued for Parts of New England

Image
The Storm Prediction Center in Norman, OK has issued a Severe Thunderstorm Watch until 11 PM for a significant portion of New England.
The primary threat will be damaging winds, although hail up to 1" in diameter and isolated tornadoes are possible.  The initial radar is rather quiet although there is a severe storm right now around Laconia, NH.
However as a weak impulse moves through the Hudson River Valley into New England
and into temperatures near 90, with dew points into the 70s more thunderstorms should develop,
South of the Mass Pike should be ok through early evening.  Activity may organize into a convective complex after dark.  This complex would likely bring heavy rain and strong winds with it so keep tabs on the situation throughout the afternoon/evening.

If anything major happens I will update my post.
