Severe Weather Coordination Message #2 – Friday 3/20/20 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms remain possible across Western and Central Massachusetts and Connecticut late Friday Afternoon and early evening between 4-8 PM. Strong to Damaging Winds, heavy downpours and the possibility of a rotating storm are the primary threats. Its noted that there may not be much lightning with the activity..
..The Storm Prediction Center (SPC) has continued a marginal risk for severe weather for Western and Central Massachusetts and Connecticut..
..Monitoring the potential for accumulating snow Monday Night into Tuesday Morning for portions of Southern New England. Details will become clearer on this potential later this weekend..
..SKYWARN Self-Activation will monitor the severe weather potential for Friday Afternoon and Evening..
An unseasonably mild day will set the stage for the potential for isolated to scattered strong to severe thunderstorms along and ahead of a strong cold front that will sweep through the region and bring colder air for this weekend. There are no significant changes to the current thinking. The key factors on the severe weather potential include the following:
1.) This will be a low instability/high shear environment. Given the low instability, it will be a question of whether the high shear is enough to compensate for somewhat limited instability.
2.) Amount of cloud cover/showers during the day and how that affects heating for temperatures to reach the upper 60s to around 70 degrees. This will impact the level of instability even though it will likely still be fairly low but still will be a key factor in the severe weather potential and if the high shear environment can compensate for the lower instability.
We are also monitoring the potential for accumulating snow in portions of Southern New England for Monday Night into Tuesday Morning. Details will become clearer on this potential later this weekend.
SKYWARN Self-Activation will monitor the severe weather potential for Friday Afternoon and Evening. This will be the last message on the severe weather potential as we move into monitoring and operations modes. Coordination messages on the storm system for Monday Night int Tuesday will commence as needed over the weekend.
