.DISCUSSION...
.KEY MESSAGE 1...
A confluent mid level flow over the Northeast, between the
northern and southern branches of the polar jet, will shift
offshore on Saturday, thus allowing high pressure over eastern
Canada and the Northeast to gradually retreat offshore. At the
same time, a southern branch upper trough over the Mid and Upper
Mississippi Valley will allow subtrop jet moisture and energy
to be drawn northward in tandem with a warm front and multiple
waves of low pressure. Rain will gradually overspread the area
Saturday, from SW to NE, likely persisting into Sunday afternoon
before drying out west to east. Rain could very well linger
into the evening hours, especially across eastern LI/SE CT.

This will be a stratiform rain event (non-convective), with max
rainfall rates topping out at 2 to 3 tenths an hour. Embedded
thunderstorms seem unlikely at this time. Storm total rainfall
amounts are forecast to be between 1 to just under 2 inches,
highest across LI and the NYC metro. NBM probabilities for
greater than 2 inches are about 40-50 percent across this same
area, falling off quickly to the north.

Gusty E winds over the weekend (20 to 30 mph Sunday), along
with the rain will keep highs mainly in the 50s to lower 60s.
Lows will be in the mid 40s to mid 50s. This will be about 5 to
10 degrees below normal.

.KEY MESSAGE 2...
A large mid to upper level ridge may begin to build towards the
northeast midweek. This will help bring a return to dry conditions.
Temperatures may reach the upper 70s and lower/mid 80s for
highs by next Wednesday. However, 12Z globals are pointing
toward an upper trough closing off over the Northeast into
eastern Canada Wed into Thu. Should this scenario become the
solution in subsequent model runs of the guidance, much cooler
conditions will be on tap. This is not reflected in the latest
forecast.

increasing E flow bringing wind gusts to 25-30 kt Saturday
afternoon into Sunday. A few gale force gusts late Saturday
night into Sunday will be possible. Seas on the ocean will build
to to will also build to 7-10 ft. Winds will gradually subside
below SCA levels late Sunday and Sunday night, but ocean seas
