Good Morning and Happy Friday!
Longwave trough lingers over the eastern seaboard this morning.
The axis of the trough moves offshore this afternoon as heights
begin to rise aloft. Cyclonic flow around the trough and its
upper low over the Canadian Maritimes will likely bring
scattered to potentially broken stratocumulus through the early
afternoon. Forecast soundings indicate moisture trapped beneath
an inversion around 3 to 4 kft. This moisture diminishes later
in the day and skies should begin clearing late in the
afternoon.
The East End and CT will lie between low pressure across the Canadian
Maritimes and high pressure building from the Great Lakes. The pressure gradient between these two systems continues a gusty NW flow. However, gusts should not be as strong as Thursday peaking around 25 mph on the East End & CT.
High temperatures will be in the upper 50s, a few degrees below normal for this
time of year.
Ridging will build over the East End both at the surface and
aloft tonight. The pressure gradient weakens and winds diminish
this evening. Good radiational cooling conditions are
anticipated with mostly clear skies, light winds, and a dry air
mass. Temperatures across the up island areas and interior of southern Connecticut should bottom out in the middle 30s. Areas of frost are possible up island and interior CY above I-95 and the Merritt Parkway. Temperatures should
stay above freezing. At the East End and SE CT, temperatures should
fall into the upper 30s and lower 40s. The Long Island Pine
Barrens likely fall into the middle 30s, and possibility of patchy frost there.
Tranquil conditions are forecast Saturday with the surface high
pressure and upper ridge overhead. Highs will continue a few
degrees below normal in the upper 50s and lower 60s.
High pressure moves overhead Saturday night and will
be moving offshore Sunday. Light winds and mostly clear sky
conditions will lead to ideal radiational cooling. Vast range of
lows forecast from guidance. There will be potential
for frost for inland valleys and rural sections where lows will
be in low to mid 30s and low levels become saturated.
The low passing offshore southeast of Long Island Sunday into
Sunday night will be extratropical, originating from a tropical
disturbance over the Gulf of Mexico a few days prior. The low
weakens and lingers nearby offshore Monday. High pressure gets
more established in the Canadian Maritimes during this time. The
low may impact the region and NAM indicates a more close
approach of that low. Forecast has low chances of rain showers
on the East End and CT for Sunday afternoon into Sunday night. Dry
conditions forecast to return Monday with a brief reemergence of
high pressure from the northeast. Have a great weekend!
