Short term...
very progressive but dry pattern will continue. Upper troughing
will continue to maintain the expansive Rosby wave over two thirds
of the Continental U.S.. once the cold front passes Monday morning...dry cold
air will simply replace the same. But this time a little more wind
will accompany along with some cloudy skies moving in from the
north. This should be all we see with this system. As the upper
thermal trough moves out...a few short waves moving down the back
side of the larger Rosby wave will move near the area providing
cloudy skies from time to time. Otherwise...dry cool conditions
will remain through the week.

Long term...
another dry front will move through Wednesday. The one after that should
be in for the weekend. This front is expected to stall near the
coast and does not look to have any real chance of producing
precipitation either...but what is being resolved in the mass fields is
quantitative precipitation forecast that looks like rain along the frontal boundary. This would
not be the case as the fcasted environmental inversion in sounding
profiles over the frontal region would be at least moderate enough
to keep any sh/ts from developing. Therefore what the model mass
fields look to be resolving is very thick dense fog for next
weekend...which would make a lot more sense. But this is a long
way out for fcasting fog which can be very tough even 24 hours
out.

Aviation...
VFR conditions will continue at all of the terminals through the
forecast period.

Marine...
a surface ridge will settle over the area this afternoon and
evening allowing for a temporary easing of winds and seas. By
Monday...a reinforcing Arctic front will push into the area. As
the Arctic ridge builds in behind it...strong boundary layer winds
of 35 knots will easily mix down to the surface beginning Monday
night and persisting through Tuesday. Sustained winds of 30 knots
with frequent gusts to near 40 knots will be likely. Small craft
advisories and gale watches have been issued for Monday and into
Tuesday. The pressure gradient over the Gulf will begin to relax
Tuesday afternoon and Tuesday night as the surface high becomes
more centered over the area.
