.AVIATION [06Z TAF Issuance]...
Per KHGX VWP, a NE flow aloft has set up across the area at this
time...with a more easterly flow noted at the lower levels. This
pattern is helping to produce isolated showers along our immedi-
ate coast (more scattered over the coastal waters). As such will
keep with the mention of VCSH/VCTS in for the LBX/GLS sites this
morning (i.e. now until mid morning or so). Further inland, will
also keep the mention of lower CIGS around sunrise. The question
for tomorrow remains the possibility of isolate/widely scattered
activity over the southern half of the CWA during the afternoon/
early evening. Short-term models are also indicating that a band
from Hurricane Ida could make it here right around to just after
the end of this TAF period. 41

.PREV DISCUSSION... /ISSUED 248 PM CDT Sat Aug 28 2021/
LONG TERM [Monday Through Saturday]...
As Ida continues to move northeastward away from the Gulf Coast,
global models are in agreement on a surface trough being left in its
wake right along our coastline. Moisture remains elevated with PW
values ranging from 2.0"-2.2" mainly south of I-10 through at least
Wednesday. This trough will effectively serve as a convergence zone
for the moisture leading to persistent PoPs offshore and for the
coastal counties. It is important to note that the location of the
moisture axis and surface trough is highly dependent on both the
track and weakening of Ida as she continues her northeastward trek
over land. As of the 12z model runs, confidence is fairly high given
that total PW anomalies in the ensembles are sufficiently positive
and are consistent with their placement as well. There is also
fairly good agreement that Ida will evolve into a longwave trough
that extends to the Gulf Coast Tuesday into Wednesday, which also
adds into the extended stay of the moisture axis into midweek.
On the backside of that trough is...you guessed it...an upper-level
ridge that expands eastward throughout the week. It won't be a
particularly strong ridge (591-592 dam), so diurnally driven
convection will still be feasible with PW values remaining elevated
(1.8"-2.2") through Thursday. Unfortunately, an upper-level ridge
building also means the return of hotter temperatures as well. High
temperatures next week will make a return back to the mid-to-upper
90s. Friday into Saturday is a bit interesting...a jet streak wraps
around the upper-level ridge bringing in drier air from the north
(PW values decreasing to below 1.5"). There is a bit of uncertainty
in how much dry air filters in. The GFS is by far the driest of the
models, and the Euro/Canadian have drier air in the northeastern
counties with lingering moisture along the coast and in the
southwestern counties. For PoPs going into the weekend, leaned more
towards the Euro/Canadian scenario so rain chances will be higher to
the south and southwest.
