Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible over Western Massachusetts and Western Connecticut Sunday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy downpours with urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has placed Western Massachusetts and Western Connecticut in a marginal risk for severe weather anytime after 4 PM Sunday..
..SKYWARN Self-Activation will monitor the severe weather potential for this Sunday Afternoon and Evening..

Another round of isolated to scattered strong to severe thunderstorms are possible for Sunday Afternoon and Evening as a warm front moves through Sunday Morning with the cold front sweeping into the area late Sunday Afternoon and Evening. The headlines depict the current thinking. Key factors include:

1.) Clearing after morning showers and possible embedded non-severe thunderstorms.
2.) Frontal position and timing to the area presuming sufficient clearing for destabilization.

SKYWARN Self-Activation will monitor the severe weather potential for this Sunday Afternoon and Evening. Another coordination message will be posted by 11 AM Sunday Morning.
