Severe Thunderstorm Warning 44, NWS Houston/Galveston, TX

Area Forecast Discussion
National Weather Service Houston/Galveston TX
654 PM CDT Sat May 26 2018

.AVIATION [00Z TAF Issuance]...
Widely scattered thunderstorms have managed to develop across the
southern half of the CWA this afternoon along the seabreeze. Will
also have to keep an eye to the east as outflows from storms near
the Sabine River move in this direction. Did add VCTS for IAH and
keep the TEMPO group in for HOU for the next hour or so as a pre-
caution. Otherwise, will keep with the brief lower CIG trends for
overnight/early Sun morning. Given the events today, not going to
question the possibility of scattered TSRA tomorrow afternoon too
much at this time. 41

.PREV DISCUSSION /Issued 353 PM CDT Sat May 26 2018/...

Lower level high pressure planted over the northwestern Gulf with
the very slight northwestward movement of Alberto and southwestern
upper ridging keeping eastern Texas under a pronounced northerly
flow pattern. Warm and muggy overnight conditions will be more
tolerable per an evening southerly breeze. As winds weaken below 5
knots under mainly clear skies...the probabilities for rural county
fog will be on the rise. Early Sunday patchy fog development will
likely be focused just north and west of Galveston Bay (sans the
metro area of course). As Alberto nears the Florida Panhandle
tomorrow afternoon there may be a weak disturbance that rotates
around his backside and clips extreme (south)eastern Texas. If
this weaker PVA does pass through from mid morning through late
afternoon it will be moving into a heated, fairly moist and
unstable environment. Thus, have low end POPs in place Sunday for
the southern two thirds of the forecast area to account for the
daily evolution of more numerous late morning into afternoon
scattered showers and thunder. The main threats with the strongest
storms will be downburst winds. Small hail production and very
brief heavy rainfall rates leading to short term nuisance low-
lying area/roadway flooding.

Other than some slight chances for sea breeze convection Tuesday...
this near term through the extended period forecast strictly becomes
a temperature-themed affair. Relatively drier air moving in on
Monday and an amplifying northern Mexico upper ridge across the
state will likely place us under a heat wave throughout the
remaining days of the month. Subsequent days of greater than 90F
will likely break the most frequent days above 90s for the month
of May (currently at 15 for the month at IAH)...so odds are very
good that this year will replace 2003 for the top ranking. On a
more serious note...heat indices will certainly be dangerously
high. With maximum temperatures forecast in the middle to upper
90s by mid to late week, lower to middle 70 PM dew points,
relatively weaker winds and ample sun will push afternoon heat
indices into the Heat Advisory realm of 108 F or greater. Of
course, hydration and remaining in cooler environments during the
afternoon hours is key to your health. No matter your physical
conditioning it is recommended to limit any outdoor activity
during this coming week. 31
