Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1213 PM CST Tue Feb 6 2018

.AVIATION...
IFR/LIFR cigs will continue through the remainder of the afternoon
and evening, as overrunning continues to increase atop the shallow
cold air dome in place near and N of a stationary front extending
from Deep E TX into Cntrl LA. Vsbys will be reduced in areas of
-RA/-DZ that develop near and N of the front, with patchy dense FG
possible at LFK through late afternoon. Should start to see
deeper convection develop after 00Z Wednesday over portions of E
TX into N LA/SW AR along and just N of the front, as a weak
frontal wave develops and shifts ENE across Ncntrl LA. This may
result in minor improvements to cigs, before the convection
begins to diminish from NW to SE after 06Z. The convection should
end across the TYR/GGG/TXK terminals by 10Z, SHV/MLU by 12Z, but
the post-frontal rains look to persist through early to mid-
afternoon Wednesday over Deep E TX and the Srn sections of Ncntrl
LA. Once the rains end late tonight/after daybreak Wednesday,
should see a slow improvement to cigs, which will become MVFR
across much of E TX by or shortly after 12Z, and SW AR/extreme
Nrn LA prior to 18Z. Additional improvement to VFR is expected
Wednesday afternoon over all but Deep E TX and the Srn sections
of Ncntrl LA. ENE winds 5-9kts this afternoon will become NNW
7-12kts later this evening, with gusts to 20kts over the Wrn
sections of E TX. /15/
