An unusually strong cold front/squall line;
https://en.wikipedia.org/wiki/Squall_line
is moving towards the state. Imbedded in the front are thunderstorms and gusty winds. Although the Northern Islands will get hit the hardest, wx effects will be felt here Mon./Tues. possibly into Weds. Because the winds will be S/SW they will be counter to our prevailing NE flow.
This wind direction is contrary to prevailing so it’s much easier to get wind damage. Trees are used to the wind from a certain direction so when conditions develop with winds coming from the opposite direction they are vulnerable. Fortunately for the BI the front/ squall line will weaken as it moves East. It will fracture and break up into pieces by the time it gets here. Still thunderstorm chances will be present here as the cold air is unusually far South and CAPE values will be elevated but not extreme.
