Dangerous heat, humidity and storms

.Surface chart and radar

A cold front will be moving through our region later today and overnight into early Wednesday.  Thunderstorms are already firing up along and ahead of the front in Canada. We’ve already had a thunderstorm complex move across Maine this Morning. More organized storms will likely move into northern parts of the region late this afternoon and evening. There is a good chance these will continue into the overnight.  

The Storm Prediction Center (SPC) has placed the northern parts of our region close to the Canadian Border under an Enhanced Risk for severe weather. Any storms that form could quickly become severe.  the greatest risk will be damaging winds, with gusts of 70+ mph possible, moderate to large hail, heavy downpours, and frequent lightning. There is a higher risk for tornadoes.  The SPC  has a 2% and 5% risk for tornadoes across a large part of the northern half of our region. There is a chance for a strong tornado to occur, so keep weather aware.  South of there the risk drops to a Slight one across the rest of northern New York State, central Vermont, central New Hampshire, and southern Maine.  Not everyone will see severe weather today, but those who do will likely be across northern parts of the region.

Today is going to be very hot and humid. For this region Heat Advisories are up across a large part of the region with Extreme Heat Warnings up for parts of the I-95 Corridor.  We do have a few troughs over southern New York State, Pennsylvania and the Middle Atlantic, these could produce an isolated shower or thunderstorm, but most won’t see them.

Tomorrow the heat dome is going to push out of northern parts of the region. But the ridge out of Canada, is going to push farther east over the rest of the region. While the northern areas will be cooler and less humid tomorrow, the rest of the region will become even warmer with higher dewpoints due to a northwest flow out of central Canada, where temperatures are well above average. The flow will also allow some Canadian wildfire smoke to move over parts of the region, creating. air quality issues. This general setup will be in store for the region into Friday. With troughs over the region along with a few weak cold fronts moving through, producing the chance for isolated showers and rouge thunderstorms. Most of y’all won’t see any rain. These fronts won’t make any real relief from the heat.

Later Friday will see a cold front slowly drop through the region, with the cold front scattered showers and thunderstorms are likely. Some of these could be strong to severe, with the chance for damaging winds, hail, frequent lightning and heavy downpours.

Saturday a warm front followed by a cold front will bring the chance for showers and thunderstorms, some of these storms will likely be strong to severe. For Sunday another cold front will drop through, bringing the chance for some showers and thunderstorms. Monday we will have high pressure trying to build into the region. But we’re likely to have a trough lingering keeping the threat for showers and storms. We will have to wait and see if any tropical moisture works in out of the Ohio Valley.

Starting on Friday and going into the first part of next week, we’re going to see temperatures and humidity levels drop more and more each day; By Tuesday we should have very seasonal conditions overhead.  

 Have a great day!
