Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1133 PM CST Tue Dec 12 2017

.AVIATION...
VFR conditions will continue through the 13/06Z TAF period. SKC
will prevail overnight through Wednesday, although some cirrus
currently over S TX should continue to shift ENE into portions of
Deep E TX and SE TX, as well as Cntrl and S LA by mid-morning
Wednesday. Sfc ridging in place across the region tonight will
result in calm/Lt and Vrb winds. However, the pressure gradient
will tighten by mid to late morning ahead of a cold front that
will shift S into N TX/SE OK/Wrn AR by afternoon, resulting in SW
winds increasing to 10-15kts with gusts to 18-22kts over much of
the region. These winds will diminish to 5-10kts after 00Z. /15/

DISCUSSION...
Clear skies, dry air, and light winds have allowed temperatures to
cool quickly tonight. No major changes were made to the going
forecast, although minimum temperatures were lowered by a few
degrees across East Texas, so all locations should fall below
freezing tonight. Otherwise, some minor updates were made to the
hourly trends.

A Fire Danger Statement has been issued areawide for Wednesday.
Southwest winds will increase into the 10 to 15 kt range, with
higher gusts across East Texas, during the day Wednesday. Combined
with the already dry air mass in place, relative humidity values
are expected to fall to below 25 percent areawide and to near or
below 20 percent across most of the area north of a line from
Tyler, to Shreveport, to El Dorado.
