Severe Thunderstorm Warning 77, NWS Houston/Galveston, TX

Area Forecast Discussion
National Weather Service Houston/Galveston TX
1247 AM CDT Sat May 4 2019

.AVIATION...
North-south oriented line of tsra will be moving east at 25-35 mph
and will be impacting the IAH, LBX, SGR, GLS terminals in the next
several hours. Look for 25-45kt gusts as it passes thru along with
some very heavy, albeit fairly brief rain rates of 2-3"/hr in the
core of the storms. Lingering light rain will persist for a few
hours then gradually move off to the east. Should see VFR
conditions in the storms wake with some sunshine by mid morning.
Questionable whether we'll see any precip redevelopment later in
the day with heating. For now, will go the optimistic route and
not include the mention in the TAFs attm, but it will need to be
reevaluated by later shifts.  47

.PREV DISCUSSION... /ISSUED 804 PM CDT Fri May 3 2019/
Our brief respite between convective systems is about to end as
large MCS/MCC is evolving over central TX early this evening.
Storms are beginning to get more organized into a linear structure
with pronounced sely motion getting established. Expect this MCS
to track quickly southeast through the rest of the night, with ewd
development into sern TX as main line surges towards the coast.

Have cleaned up forecast in wake of earlier storms, and tried to
time arrival of next round of tstms starting far nw counties
8-9pm and perhaps moving across Houston metro around 12a-3a
window when it will also be reaching the middle TX coast. Intense
rainfall rates can be expected with these storms, likely causing
flash flooding especially over areas already drenched over the
past couple of days. Will keep Flash Flood Watch in place to cover
those locations, mostly along and north of I-10. However, these
storms will be capable of localized flooding even outside the
watch. Fortunately the complex/line will be moving quickly and
should not linger over any one location. Although, this will
increase the potential for strong to damaging winds as the line
blows through. Large hail and an isolated tornado or two are also
in play through the night with the stronger cores.

In wake of this impulse, could still see lingering tstms through
the morning, but then generally expect most of the rain/tstms to
pull away as mid/upper level impulse continues moving ewd tomorrow.
