Area Forecast Discussion
National Weather Service Shreveport LA
1132 AM CST Sat Feb 13 2021
.AVIATION...
For the 13/18Z TAF update, low stratus clouds continue to keep
MVFR cigs in place across most of our terminals with marginal VFR
cigs improvement possible by 14/00Z. By 14/10Z, most terminals
begin returning back to MVFR and potentially IFR for KLFK as our
winter storm impacts begin with -FZRA quickly entering our entire
airspace. Toward the end of the period, -PL is possible at KTXK,
however, -FZRA could arrive there first. Low level northerly flow
and mid-level southwesterly flow could present marginal LLWS
hazards, especially during the daytime hours. /16/
&&
.PREV DISCUSSION... /issued 1001 AM CST Sat Feb 13 2021/
UPDATE...
Low stratus continues to blanket all of the Ark-La-Tex this
morning, and surface temperatures remain below freezing almost
everywhere except for our southern zones. Cold air advection,
also ongoing, is evident in this morning's KSHV sounding, with a
cold nose approaching -8 degrees Celsius, down about two degrees
in 24 hours or almost seven degrees in 48 hours.
Therefore, afternoon high temperatures and sky grids were
adjusted accordingly. Otherwise, no additional forecast
adjustments were necessary at this time. /16/
