Area Forecast Discussion

.WHAT HAS CHANGED...
Cold Weather Advisories now include late tonight into Sunday
morning.
&&
.KEY MESSAGES...
1) Cold temperatures combined with increasing winds expected to
produce wind chills within advisory levels late tonight into Sunday
morning. Winds expected to remain below advisory levels.
2) Minor tidal flooding possible Sunday into Monday.
&&
.DISCUSSION...
.KEY MESSAGE 1...
Wind chills through this morning may be just short advisory criteria
in some areas, but no plans to cancel it at this time. For tonight
into Sunday morning, models are in better agreement regarding low
temperatures. The cold temperatures combined with increasing
northerly winds are expected to produce wind chills across the
forecast area to be within or at least close to advisory thresholds
once again. Cold Weather Advisories have therefore extended to
address late tonight into mid-Sunday morning. The cold wind chills
could result in hypothermia if precautions are not taken.
The strongest winds associated with a strengthening storm well
offshore would appear to be Sunday morning into early afternoon.
Coastal areas likely see gusts 30-40 mph during this time. A few
gusts to 45 mph are possible as well, but confidence continues to
increase that a wind advisory will not be necessary.
Any snow that clips eastern Long Island late tonight into Sunday
morning would not have much, if any, impact.
.KEY MESSAGE 2...
The combination of spring tides and deep offshore low pres may
result in periods of minor tidal flooding starting with the Sun mrng
high tide cycle, lasting into Mon. The modeling has been consistent
keeping the threat in the minor category, especially since
confidence has increased in winds lacking an ely component thru the
period. Statements or advisories may be needed, however, the extent
of the ice on area waters may be a significant limiting factor.
&&
.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
High pressure over the region weakens this afternoon into
tonight. An area of low pressure moves northward along the coast
tonight and out to sea on Sunday.

.MARINE...
Northerly winds increase late tonight into Sunday with a
strengthening storm well offshore. Freezing spray advisories have
been posted for the ocean waters and LI Sound this evening through
early Sunday afternoon. Have now upgraded to a Gale Warning for all
waters for late tonight through Sunday, and for the ocean, this
includes the first half of Sunday night. Advisory conditions then
follow through Monday for most of the waters with diminishing winds.
Seas on the ocean probably are still elevated into Monday night, but
sub-advisory conditions for all waters finally occurs Tuesday
morning. A weak pressure gradient then sustains relatively tranquil
conditions through the mid-week period.
