Severe Weather Alert Descriptions

 Areal Flood Advisory  Statement as of 9:53 PM CDT on July 31, 2014


The National Weather Service in League City has issued a

* Flood Advisory for...
eastern Montgomery County in southeast Texas...
northern Harris County in southeast Texas...
southeastern Walker County in southeast Texas...
northwestern Liberty County in southeast Texas...
south central Polk County in southeast Texas...
San Jacinto County in southeast Texas...

* until 1145 PM CDT

* at 951 PM CDT... Doppler radar indicated heavy rain due to
thunderstorms. Some storms were intensifying in the advisory area
with rainfall rates of 2-3" per hour. This will cause minor
flooding in the advisory area.

* Some locations that will experience flooding include...
southeastern Huntsville... Cleveland... Shepherd... Splendora... Patton
Village... Roman Forest... Woodbranch... Cut and Shoot... New
Waverly... Coldspring... Plum Grove... Goodrich... North Cleveland...
Porter heights... Huntsville State Park... New Caney... Evergreen...

Precautionary/preparedness actions...

Excessive runoff from heavy rainfall will cause ponding of water in
urban areas... highways... streets and underpasses as well as other
poor drainage areas and low lying spots. Do not attempt to travel
across flooded roads. Find alternate routes. It takes only a few
inches of swiftly flowing water to carry vehicles away.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams... as well as farm and country roads. Do not
attempt to travel across flooded roads. Find alternate routes.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
652 PM CDT Thursday Jul 31 2014 


Discussion... 
see aviation for 0z taf issuance. 


&& 


Aviation... 
showers and thunderstorms are now into College Station and 
forecasted to continue to push to the southeast this evening. High 
res models have struggled initializing as all but the rap missed 
this afternoons precipitation near ksgr/ klbx. Because of the above have 
leaned towards rap with evolution of showers and thunderstorms. 
Most likely this line will move into kiah and khou in the next two 
hours before starting to weaken. Looks like most taf sites will 
see thunder with klbx and kgls still in question on whether 
current convection will make it or not. Global models then begin 
to differ on how the front will progress tomorrow morning. The GFS 
plunges the drier air farther to the south while the NAM holds the 
drier air up just around kiah tomorrow. If the NAM is right rain 
could linger around near and south of kiah tomorrow. If the GFS 
is right the precipitation will be confined more near the coast. Future 
taf packages will work to narrow down when and where the front 
will stall. Either way behind the font precipitation looks to come to an 
end. 23 


&& 


Previous discussion... /issued 627 PM CDT Thursday Jul 31 2014/ 


Update... 
heavy rain threat looks to be rapidly taking shape over the 
northern 1/3 of the area. Areas from Caldwell to College Station 
to Madisonville have ongoing thunderstorm that moved off the 
frontal boundary and generally moving at 15-20 knots to the southeast. 
Seabreeze and outflow boundary from storms in the metropolitan marching 
inland and the collision area looks to favor something 20 miles either 
side of a line from Brenham to Navasota to Cut and Shoot to 
Livingston. Have done a quick update to add locally heavy rainfall 
and raised probability of precipitation for this corridor. Precipitable water 2+ inches pooled in there 
and a boundary collision look to favor at least a few hours of 
heavy rain. Storm motions should slow and some backbuilding may 
occur...latest satellite precipitation estimate statement highlighting this threat as well. 
45/23 


Previous discussion... /issued 325 PM CDT Thursday Jul 31 2014/ 


Discussion... 
a northwesterly flow aloft will help push a cold front into southeast Texas 
tonight and Friday morning...and then off the coast late Friday. 
Leaned heavily on the 12z nam12 although a model consensus agreed 
with the NAM output. The main forecast challenge for tonight 
through Friday is thunderstorm coverage. 


Weak shortwave troughs moving through the flow aloft may help 
generate thunderstorms ahead of the cold front. The seabreeze has 
helped generate thunderstorms to the southwest of metropolitan Houston. 
Expect these will be fairly scattered this evening. Overnight 
should see more widespread coverage ahead of the front as it sinks 
into the forecast area. There may be a break in the coverage later 
Friday morning before redevelopment Friday afternoon. The front 
should work its way along the coast by Friday night. That said... 
the models have backed off of the rainfall potential...especially 
on Friday. Model soundings have the best precipitable water/S of about 2 inches 
tonight and early Friday. The nambufr forecast soundings show that 
the best chances for isolated strong storms will be late this 
afternoon and early evening. 


The front will move back inland and the subtropical ridge will try 
and build back over the area next week. This will lead to a warmer 
and more humid trend during the first half of the week. 


40 


Marine... 
light to occasionally moderate onshore winds will continue through 
tonight. A weak cold front will approach the coast on Friday... 
probably stall and meander back and forth near the coastline 
through the weekend. This boundary should serve as a focus for 
periods of showers and thunderstorms. Light and variable winds 
should persist with low seas... except in and near storms. An 
onshore flow is expected to return to the area with winds and seas 
remaining below caution levels. 47 


Previous discussion... /issued 1209 PM CDT Thursday Jul 31 2014/ 


Aviation... 
not too many changes to ongoing taf package...mainly to push back 
tempos a few hours. Frontal boundary making slow progress toward 
southeast Texas. Sat imagery does show some breaks in clouds ahead of it 
which should allow some destabilization in advance. GOES precipitable water 
estimates 2-2.3" precipitable waters across the area. Do anticipate increased scattered 
activity to develop across north half of southeast Texas this afternoon...then 
sagging southward toward 1-10 & metropolitan areas during the evening and 
nighttime hours. Several models showing further 
enhancement/redevelopment between 1-7am CDT south of a Columbus- 
Livingston line so kept vcts's going overnight at least until 
trends & increased confidence can be established. Considering 
deeper available moisture...rainfall could be locally heavy at 
times. Probably see a break after sunrise...followed by possible 
more scattered activity during the afternoon depending where the boundary 
becomes situated and if we can get some instability. 
Otherwise...VFR outside of convection. 47
