Area Forecast Discussion
National Weather Service Shreveport LA
1114 AM CST Thu Feb 23 2017

.UPDATE...
Have updated the forecast to bump the afternoon highs for
portions of East and Northeast Texas and lower the dew points
for the same region. This will make for some lower relative
humidity values for today with the spread of temperatures and
dew points.

&&

.DISCUSSION...
A pressure gradient between surface low pressure over the
Rockies and out into the Plains and high pressure over the
Southeast States will produce strong and gusty of 15-20 MPH with
higher gusts to near 30 MPH for much of the day and possibly
into the evening for parts of Northeast Texas and Southeast
Oklahoma. A Lake Wind Advisory will remain in effect through 6 PM
CST for this area. The lake wind advisory may have to be extended
into the evening if the winds look to remain elevated. /06/

.PREV DISCUSSION... /issued 550 AM CST Thu Feb 23 2017/

AVIATION...
For the 23/12z TAFs, patchy fog across Deep East Texas, the Toledo
Bend Country, and portions of North Central Louisiana has lead to
some instances of MVFR flight conditions, and even LIFR at times
at KMLU. However, the fog is expected to dissipate by mid
morning, and all sites should be in the VFR range by 23/15z.
Only some high clouds are expected for much of the day along and
north of Interstate 20. During the daytime, Southerly winds will
increase to between 10 and 15 kts with higher gusts between 20 and
25 kts, especially across East Texas. Wind speeds will diminish
slightly overnight, but will likely continue to be between 7 and
12 kts. The strong southerly flow is expected to bring low clouds,
patchy fog, and MVFR flight conditions along and south of
Interstate 20 during the overnight and early morning hours of
Friday.
