A Few Strong To Severe Thunderstorms Are Possible Between 12 & 5 pm This Afternoon Across Western & Central Mass: The shower and thunderstorm activity that is currently moving across parts of southern New England will push offshore by or before 9 am this morning.
There is then expected to be a period of dry weather from about 9-10 am this morning to about 1-2 pm this afternoon. In fact, I expect that there will be some breaks in the clouds which will allow some sunshine for a few hours late this morning into early this afternoon. This will cause temperatures to rise into the 83 to 87 Degree range with some very humid conditions. In addition, this will also cause the atmosphere to become moderately unstable by early this afternoon across all of Western and Central Mass and very unstable across areas near and south of the Mass Pike. This will set the stage for the potential of a few strong to severe thunderstorms this afternoon with the highest severe weather risk across areas near and south of the Mass Pike.
Thunderstorms are expected to develop across northern and far Western Mass by 12-1 pm. These thunderstorms are expected to intensify as they move southeastward into a more unstable air mass. Current indications are that thunderstorms may reach the area around the Mass Pike, including Worcester and Springfield by 2-3 pm this afternoon and then push out of Massachusetts and into Connecticut and Rhode Island by about 5 pm this afternoon.
The main risk from any severe thunderstorms this afternoon will be strong wind gusts of up to 50 to 60 mph. Large hail is also a possibility with some of the more severe storms. In addition, locally very heavy rainfall with localized urban and poor drainage flooding is also possible. The tornado threat is EXTREMELY LOW.
So, To Sum Things Up – There is the possibility for a few severe thunderstorms between 12 & 5 pm this afternoon with the greatest threat for severe weather across areas near and south of the Mass Pike. Main severe weather threat will be strong wind gusts. Large hail & locally very heavy rainfall is also a possibility.
I will be monitoring the thunderstorm activity closely for you and will have frequent updates as conditions warrant.
A Couple Of Strong To Severe Thunderstorm Possible Sunday Afternoon Across Western & Central Mass: A rather strong piece of energy is expected to push across Western & Central Mass during Sunday. This weather feature will combine with an unstable atmosphere to produce another round of thunderstorms to move from northwest to southeast across southern New England during Sunday afternoon.
Even though the environment will not be quite as favorable for severe weather on Sunday as it is today, it will be just favorable enough for a couple of strong to severe thunderstorms during Sunday afternoon. Large hail will be the main threat with any strong to severe thunderstorms with gusty winds also possible.
