.AVIATION [00Z TAF Issuance]...
SHRA activity has remained well east of all terminals this
evening, with activity expected to diminish upon the loss of
daytime heating over the next couple of hours. VFR cigs should
hold on for the next 6 hours or so, though a return to MVFR to IFR
cigs should come overnight as moisture levels increase and a
fairly persistent stratus deck develops across the region. HiRes
guidance continues to indicate the development of showers and
storms tomorrow, beginning offshore in the morning and becoming
widespread during the afternoon. With increasing confidence in
precipitation coverage, have included SHRA wording in the TAF
package.

.PREV DISCUSSION... /ISSUED 343 PM CDT Thu May 20 2021/
Short Term [Through Friday Night]...
Iso/sct shra will diminish in coverage this evening. Stratus and
perhaps some patchy fog will fill back in overnight. East coast
ridging will very slowly expand westward in the coming days. This
will nudge a weak inverted sfc trof into the upper Tx coastal
waters Fri. Long fetch of deep tropical moisture with PW's aoa 2"
will begin flowing into the region on its backside. Expect some
sct shra/tstm development in the Gulf waters before sunrise to
gradually expand in coverage and move inland during the mid-late
morning hours Fri. Fairly good precip coverage anticipated as the
day wears on with the aid of daytime heating. No distinct
focusing mechanism noted, but can always see some localized heavy
downpours with this type airmass as well as a potential for some
training at times. No plans for a flash flood watch attm, though
we'll need to be cognizant for more localized issues that arise
from any higher rates falling over locations with the most
saturated grounds.
Think precip coverage will wane (but not disappear) after sunset.
Then, rinse and repeat the above scenario for late Friday night
as the deeper moisture axis remains in place. 47
Long Term [Friday Night through Thursday]...
S-SE flow will continue to enhance low level moisture transport
across SE Texas during the next several days, maintaining periods
of showers and thunderstorms throughout the long term period.
Starting with Friday night, the flow will help bring some of the
moisture focused over LA previously that day into the eastern
portions of the CWA. Associated PWs look to range between 2.0-2.2
inches. With drier conditions over the western sectors of the CWA,
expect the higher rain chances to occur over portions east of
I-45. The moisture will propagate westward into SE Texas Saturday,
while surface high pressure builds and expands over SE CONUS.
Increased chance in showers and thunderstorms is forecast for
Saturday, with PoPs currently in the 50-70% range for most of the
region by Saturday afternoon. Moisture axis eventually moves
further into Central TX late Saturday into Sunday but pulses of
moisture move in and out of our CWA through at least mid week.
Chance of rain decreases a bit Monday and Tuesday, but increases
Wednesday as a weak upper level shortwave moves through the
region.
Maximum temperatures will generally be in the low 80s through early
next week, increasing into the mid to upper 80s mid week. Lows will
be in the upper 60s for the northern sectors of the CWA and in the
70s along the central and southern sectors through early next
week. 24
Marine...
Unsettled weather, moderate onshore winds and elevated seas
expected thru the weekend. Will probably need some
caution/advisory flags at times. In addition, tides will be
running above 1-2ft above normal and may produce some minor
coastal/beach flooding around times of high tide. Will be issuing
a Beach Hazard Statement that includes this and the rip current
risk into Saturday. 47
