Area Forecast Discussion
National Weather Service Shreveport LA
1011 PM CDT Sat Sep 23 2017

.DISCUSSION...
A quiet evening is on tap as convection has dissipated with clouds
having almost completely faded as well. The current forecast seems
to be in good shape, and no changes are needed through the rest of
tonight. New zone package has been sent to drop afternoon wording.
Otherwise, expect temperatures to fall nicely overnight to around
70 degrees by daybreak.

AVIATION...
Isolated showers and thunderstorms are dotting the radar across
our region early this evening but should begin quickly
dissipating at TAF time so have chosen not to mention any weather
concerns to begin the package. Thus, VFR conditions should
prevail for the remainder of the evening hours. Overnight, cannot
rule out some patchy 3-5SM VSBYS at most terminal locations but
have added the possibility of dense fog at the LFK terminal in the
08z-14z timeframe as this has been the case the last several
mornings. Otherwise, any fog and/or IFR/MVFR ceiling concerns
should become VFR by late morning and through the afternoon hours
on Sun.

PREV DISCUSSION... /issued 302 PM CDT Sat Sep 23 2017/

DISCUSSION...
Isold convection ongoing across the region this aftn, as daytime
heating and sufficient moisture overpower the the influence of
the upper ridge. Weak upper low over the se CONUS will continue to
drift wwd and linger through Monday, providing some help for
isold to widely sct convection to overrule the upper ridge`s
stronghold.

Cold front/large-scale upper trof will move into the plains in the
mean time, and begin approaching our region Tuesday into
Wednesday. Some chances for rain will accompany the front,
although they will be rather low-end and focused across only the
nwrn portions of our region. The ridge will continue to hold its
ground through late in the work week, until the upper trof
/reinforced by additional disturbances/ finally is able to ride
over the ridge and force it swd. This will not mean much for us in
terms of getting any rainfall, but it will allow for the
accompanying Canadian airmass to filter into our region and cool
our temps down to a more respectable level for fall.
