.DISCUSSION...
.SHORT TERM [Today through Wednesday Night]...
Wx map shows strong cold front barreling across OK and the TX
Panhandle this morning. Across our region, moderate south to
southwesterly winds around 5-10 mph this morning keeping
temperatures in the upper 60s to lower 70s early this morning.
Radar showing scattered showers developing across Southeast Texas
and Central Louisiana as the mid to upper level shortwave
increases lift across the area.
Showers and thunderstorms will continue to increase as the upper level
lift increases with the shortwave passage, and lift front the
cold frontal passage later this afternoon. SPC has slight risk of
severe thunderstorms across Central Louisiana from Vernon, Rapides,
Avoyelles parishes northward, marginal risk elsewhere. Highest
risk of possible wind damage (15%) across the slight risk area, 5%
elsewhere. The other severe hazards possible include 5% for hail,
and 2% for tornadoes for our region. Behind the front, moderate
northerly winds will usher cooler and drier air ending the
precipitation briefly with lows in the lower to mid 40s north of
I-10, upper 40s to lower 50s further south.
The upper air pattern expected to remain from the west southwest
Tuesday through Wednesday night, keeping the region under the
influence of periodic upper level disturbances. The next such
disturbance expected Tuesday to bring another round of precipitation
later in the morning and afternoon. No severe weather expected,
as this is expected to mainly be a over-running the shallow cool
air mass event with highs in the 60s. Brief ending of the
precipitation Tuesday night, with the next disturbance brining
another round during the day Wednesday.
DML
.LONG TERM [Thursday through Sunday]...
Models show fairly good agreement through much of the medium to long
range period regarding the large scale pattern, although some
smaller scale uncertainties could impact the timing of a late week
front.
A warm advection pattern will develop by Thursday with southerly
flow between high pres centered over the eastern US and low pres in
the vicinity of KS. Aloft, zonal flow will prevail, with a weak
shortwave passing well north of the area acrs AR. A weak boundary
near the coast will begin to lift northward and serve as a focus for
a few showers or isolated storms Thursday aftn.
Flow aloft will transition more southwesterly through Friday as a
trough develops over the western states. This will allow moisture to
deepen over the region, with a few showers or tstms possible again
during the day. Abnormally warm temperatures can be expected both
Thursday and Friday with highs about 10 to 15 degrees abv normal
(near 80 areawide both days) and lows at least 20 degrees abv normal
(middle and upper 60s Friday morning).
The initial low over KS will quickly lift NE on Thursday, with
cyclogenesis forming another sfc low in the lee of the Rockies.
This low will also quickly eject off to the NE as the western US
trough amplifies and crosses the Rockies. The trough will sharpen
and acquire a more positive tilt as it emerges over the southern
plains Friday into Friday night, helping to push a trailing cold
front behind the second low toward the area. PWATs could rise
close to max values for this time of year (~1.7 to 1.8 inches per
GFS) as moisture pools in advance of the front. Forcing along the
boundary combined with energy associated with the mid/upper trough
will produce more widespread showers and tstms from late Friday
night into Saturday. While this system could pose a risk for some
strong to svr storms, there is still too much uncertainty
regarding the timing and evolution of the system to delineate any
specifics at this point.
The front is expected to progress rather quickly east Saturday, with
rain chcs ending from W to E Saturday night. Dry and cool high pres
will build behind the front, bringing a return of more seasonal
temperatures for Sunday.

stalls Tuesday morning and meanders about over the waters before
washing early Thursday morning.
