.SHORT TERM...
(This evening through Saturday Night)
Issued at 158 PM CDT Fri Mar 31 2023
The KSHV 88Doppler radar continues to show an increase in the
coverage of thunderstorms in and approaching our CWA in E TX.
Fairly stout storms just a county west of Tyler right now and more
to develop in the heat and humidity of this afternoon. Our 18Z
sounding shows the weakening cap elevating into the mid levels
with a hardy lapse rate of 8.4C/km and little change elsewhere
aloft with other key parameters. This update will soon be trumped
by our next routine zone issuance time with a full suite of 12Z
data for Tonight and a week ahead. /24/
&&
.LONG TERM...
(Saturday Night through Friday)
Issued at 330 AM CDT Fri Mar 31 2023
Starting 00z Sunday, zonal flow aloft will continue to prevail as a
sfc boundary sits south of the FA and along the Gulf Coast. Tight
packing of the sfc theta-e in the guidance shows the boundary
advancing northward through sunrise, Sunday and with a stout layer
of WAA to follow allowing for afternoon highs to top into the 80s
south of the boundary, with areas north of I-20 in the low to mid
70s given just how far north the boundary advances through the day.
With a shortwave drifting east across TX, helping to lift the
boundary north, forcing along the front should generate PoPs across
the region by the mid to late afternoon, exiting by the late
evening.
For now, guidance suggests the chance for a few thunderstorms
associated with the PoPs. As the activity exits east before sunrise,
Monday, ridging aloft will continue to amplify through the afternoon
and evening. By now, the matured sfc warm front will have worked
through the Four State Region setting the stage for a dramatic
warmup in what is setting up to become an expansive warm sector with
highs near 90 deg F. At the same time, out west, another deep
longwave trough will continue to dig across the SW CONUS and the
Four Corners region setting the stage for another chance of severe
storms Tuesday evening/Wednesday AM.
By Tuesday afternoon, an expansive long wave trough will provide
enough forcing to support a deepening sfc low off the Rockies that
will move east across the Plains before turning northeast towards
the upper Midwest. Locally at the sfc, strong southerlies will
support moisture advection northward generating 60+ deg dew points
area wide as highs trend similar to Monday, nearing 90 deg F. An
elongated dryline stretching from S/TX to as far north as S/IA will
provide the forcing mechanism for showers and storms late Tuesday,
through Wednesday AM as the cold front behind the dryline catches up
and pushes through the FA. Areas of the FA continue to remain
outlooked by the SPC for the chance of severe storms valid from 12z
Tuesday to 12z Wednesday. Continue to stay tuned to the forecast
through the weekend as we get closer to next week.
By the mid to late period of the forecast, while temperatures fall
to a comfortable level to close out the final few days of the
period, PoPs will continue to favor our region with the
aforementioned cold front now stalled along the Gulf Coast by
Thursday, before slowing trying to advance back north as a warm
front by Friday. That being said though forcing from the boundary,
continued SW flow aloft and area wide ample moisture, rain prospects
look to trend on the higher side through the remainder of the
period. Given the WPC QPF outlook to this point, would not be
shocked to see some form of an ERO mid to late next week. /53/

.AVIATION...
(18Z TAFS)
Issued at 1242 PM CDT Fri Mar 31 2023
For the ArkLaTex terminals, VFR for now with an initial line of
TS is forming along I-30 and movg NE around 60KT. Warm air aloft
is keeping bases elevated so far, but the capping aloft will erode
with heating. A second line of TS activity will be developing mid
to late aftn over NE TX and moving E along I-20 into the evening
affecting all of our sites. The HRRR model timing is preferred
with other short range generally in the same time frame for our
sites edging the line out by midnight past KMLU. SW winds will
slack speeds and gusts after sunset, but low level winds will
take more time to abate. SFC winds shift to NW by 12Z in TX and
shift W to E with sustained NW speeds at 10-20KT into the aftn.
