Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Lake Charles la
332 PM CST Wednesday Nov 26 2014
Synopsis...a dry cold front will move quickly through the area
this evening bringing another night with seasonably cool
temperatures and light northwesterly winds. Thanksgiving is
looking sunny and rather cool as Canadian high pressure builds in
with diminishing winds Thanksgiving night. A light freeze will be
possible late Thursday night in spotty areas of central Louisiana.
Short term...went cooler than guidance over eastern portions of
the area Thanksgiving afternoon where the best cold advection will
be taking place thanks to a large scale and deep upper trough
affecting the entire eastern U.S.. despite sunny skies, looks like temperatures
will remain in the middle to upper 50s east of the Sabine River.
Long term...after a cold start early Friday, a warming trend with
a southerly return flow through the weekend as high pressure
ridges in from the East Coast. There is decent agreement in Euro
and GFS models on slight chance for rain early next week ahead of
a cold front which appears to wash out on our doorstep by Tuesday.
Marine...extended the exercise caution over the coastal waters
as the cold front moves through tonight with a wind shift to northerly.
Winds should diminish Thursday afternoon as high pressure builds
in from the northwest.
