low pressure will consolidate in the Maritimes and move away to
the northeast today while pulling a cold front across the region.
Another cold front will cross the region Tuesday. High pressure
then builds across the region Tuesday night through Thursday.&&
Near term /through tonight/...
a band of rain in western areas is expected to move through
eastern areas during the middle morning hours today. This afternoon
will then be breezy with only spotty showers across the north and
drying downeast. The dense fog advisory was lifted as a
southwesterly breeze is picking up and clearing the fog.
The subtropical low to our east will quickly lift northeast and
away early this morning. Low pressure in the Saint Lawrence valley
will lift north today pulling a cold front into the area. Humid
air has resulted in some dense fog across eastern areas early
this morning. Fog is expected to dissipate later this morning as
winds increase behind departing low pressure. A band of showers
will cross the north around middle morning in association with the
approaching cold front. The midday will then be windy and mild
behind the front. Cooler and drier air will then filter into the
area later in the afternoon. Skies will be partly to mostly cloudy
over the north and mostly sunny downeast this afternoon. Tonight
will be partly cloudy, breezy and chilly as the gradient between
low pressure well to the northeast and high pressure building into
the middle Atlantic region continues to push cool air into the area.
Skies will be mostly clear downeast. Some moisture pooled in the
upper trough will bring partial cloudiness across the north.
Short term /Tuesday through Wednesday/...
a cold front will cross the region Tuesday with partly cloudy to
mostly cloudy skies and a slight chance of showers across
northern areas...with partly cloudy to mostly sunny skies
downeast. High pressure then builds across the region Tuesday
night through Wednesday night with partly cloudy/mostly clear
skies north and mostly clear skies downeast. Temperatures will be
at slightly below normal levels Tuesday/Wednesday.
Long term /Wednesday night through Sunday/...
high pressure will remain across the forecast area Thursday
through Sunday with generally partly cloudy skies north and partly
cloudy/mostly clear skies downeast. A cold front could bring a
slight chance of showers to northern portions of the forecast area
Sunday. Temperatures will be at slightly above normal levels
Thursday through Sunday.
