Many residents in Connecticut and Long Island were surprised by snow and sleet in addition to moderate to heavy rain this morning as a powerful coastal storm intensified.
The snow and sleet developed due to pockets of cold air sinking from 500 MB towards the surface this morning, illustrating the dynamic nature of this powerful upper low and coastal storm.
As we can see with the map to the left, these pockets of cold air are positioned on the south and west portion of the circulation leading to an intense thermal gradient over southern New England and Long Island.
As the day continues I expect the snow and sleet to become less of an occurrence, however it is rather clear that today will be a cold, raw day for much of the coastal plain from central New Jersey through Connecticut. Temperatures will struggle in the 40′s while strong northwesterly winds around 10 to 20 mph increasing to 15 to 30 mph will lead to wish chills in the 30′s through the day.
