.AVIATION...
For the 11/12Z terminal forecast will prevail VFR flight
categories with only few to scattered high clouds during the
day spreading into the area from the West. Surface winds will
start off light West to Southwest 7 knots or less, but increase
to 7-13 knots after 11/15Z, then lowering briefly after 12/00Z to
less 5-8 knots. A cold front will be entering into Southeast,
Northeast Texas, and Southwest Arkansas between 12/01-12/03Z
to near the Interstate 30 corridor, to near a KELD-KSHV-KTYR line
between 12/03-12/05Z, and a KMLU_KLFK line between 12/05-12/07Z.
With the passage of the boundary, winds will be shifting to the
Northwest and North 7-13 knots. /06/

.PREV DISCUSSION... /issued 452 AM CST Mon Dec 11 2017/

DISCUSSION...
Sheltered areas where winds are calm are in the mid 30s with a
light SW breeze keeping many other sites in the upper 30 or even
low 40s. There are even extremes for good measure with Mineola at
46 while Marshall is 33. Our skies are clear and dew points are
some 5 to 10 degrees cooler on average, meaning it will be a dry
day humidity wise with abundant sunshine.

In general, our fire danger will be creeping upwards in the warm
and breezy air we will see later today and perhaps a couple more
times this week. Please use caution if you have no burn bans as
the Southwest winds and usually low RH can allow a burn to get
out of control, especially during these dry mid afternoon hours.

Our next cold front will usher in Northwest winds overnight and
make for a much cooler day tomorrow with highs back below average
in the fifties. And we will keep the mercury in and out seasonal
with a secondary front on Thursday. Beyond that our next boundary
will arrive late on Sunday and overnight with a trend for these
air masses to be somewhat more modified as the big ridge out west
flattens a bit, reflecting a less direct chill influence of out
of Canada as far as cold air moving Southward. So as we move
through mid month, our heating costs will see a bit of reprieve
with some 60s and 40s compared to 50s and 30s for highs and lows.
Meanwhile, our drought conditions will continue to worsen in this
dry La Nina pattern. /24/
