Hello to all…

..SKYWARN Self-Activation will monitor for strong to damaging wind, coastal flood potential and for any rainfall amounts 1″ or more..
A strong ocean storm will track south and east of New England but then be blocked from passing complete out to sea and retrograde and loop around the 40 North/70 West benchmark. The headlines depict the current thinking. Key factors for this storm include:
1.) The track of the storm system and if gets near or inside the 40 North/70 West benchmark. That will determine the extent of the strong to damaging winds and coastal flooding in East Coastal and Southeast coastal Massachusetts.
2.) Predominantly rain is expected but some wet snow could mix in depending on how heavy the precipitation is and if it allows for the column to cool sufficiently for wet snow to occur. At this time, little to no snow accumulation is expected.
3.) Rainfall of 1″ or more could occur particularly in Eastern New England. Somewhat higher amounts could occur if the track is closer to the coast then current thinking.
SKYWARN Self-Activation will monitor for strong to damaging wind, coastal flood potential and for any rainfall amounts 1″ or more. Another coordination message will be posted by 10 AM Thursday Morning.
