As far as this weekend's "cool" forecast is concerned, here is a portion of the OKX AFD, 850 temps near 0C:
Temperatures return closer to normal for the end of this week
into early next week. An upper level low originating in the
Arctic and associated surface low drop down to the area late
Friday into Saturday. This may lead to some showers for southern
CT and Long Island. Much of the guidance has 850 temps near 0C
with this feature on Saturday. This is well below normal for
this time of year.
