Area Forecast Discussion
National Weather Service Lake Charles LA
Issued by National Weather Service Houston/Galveston TX
528 AM CST Sat Jan 11 2020
.DISCUSSION...
Updated for 12Z TAF Cycle
.AVIATION...
Line of storms has cleared BPT and LCH, and will be clearing out
of AEX by 12Z. Strong to severe storms will be impacting LFT and
ARA at the outset, and their opening line of the TAF reflects
this.
Gradually, the front will clear the whole area from west to east,
and the improvement that is already starting to be seen at LCH and
BPT will overtake the rest of the terminals. As CIGS/VSBY improve
however, gusty NW winds will take their place until those winds
diminish tonight. There is potential for fog towards dawn, but
will leave that to future TAF cycles to elaborate on further.

.PREV DISCUSSION... /issued 358 AM CST Sat Jan 11 2020/
SHORT TERM DISCUSSION...
Regional radar shows a line of thunderstorms extending from
central Louisiana into the Gulf of Mexico moving eastward at
around 30 mph. Ahead of this line, the atmosphere remains
supportive of organized convection with MLCAPE in excess of 1500
J/kg and effective wind shear in excess of 50 knots. While a few
storms have developed ahead of the line, mean cloud layer wind and
bulk shear vectors aligned roughly parallel to the orientation of
the line of convection will support the upscale growth of cold
pools and a continued predominate linear storm mode. A strong low
level jet continue to contribute to strong effective helicity with
SPC mesoanalysis, KLCH and KPOE VWPs all indicating SRH in excess
of 250 m2/s2. This effective helicity will continue to support a
tornado threat, particularly within surges along the line. These
surges will also have the potential to transport stronger winds
aloft to the surface and result in damage. Therefore, the Tornado
Watch continues for all of our Louisiana Parishes until 8 AM.
