 Flash Flood Watch  Statement as of 3:41 PM CDT on May 30, 2015


... Flash Flood Watch remains in effect through Sunday morning...

The Flash Flood Watch continues for

* a portion of southeast Texas... including the following
counties... Austin... Brazoria... Brazos... Burleson... Chambers...
Colorado... Fort Bend... Galveston... Grimes... Harris... Houston...
Jackson... Liberty... Madison... Matagorda... Montgomery... Polk...
San Jacinto... Trinity... Walker... Waller... Washington and
Wharton.

* Through Sunday morning

* a slow moving front will push into southeast Texas Saturday
afternoon through Sunday morning. Thunderstorms are expected
to develop along and ahead of the front during the afternoon.
A weak sea breeze will also develop and could possibly merge
with the front during the late afternoon. This scenario could
produce excessive rains along the Highway 59 corridor. Storms
will be slow moving and capable of producing 1 to 2 inches an
hour. General rainfall amounts of 1 to 3 inches will be
possible but there may be isolated areas of 4 to 6 inches. Any
rainfall amounts over 3 inches will cause flooding problems.

* Grounds are already saturated so any additional rainfall will
likely run off into bayous... creeks... rivers and lakes.
Typical low lying areas such as underpasses could flood
quickly with rainfall rates of 1 to 2 inches an hour.
Additional rainfall could prolong river flooding across the
area. Heavy rainfall could occur overnight Saturday which will
increase The Hazards of flooding. If flash flood warnings are
issued in your area... do not drive into flooded roads or
underpasses. Turn around do not drown.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
255 PM CDT Sat may 30 2015 


..Flash Flood Watch in effect through tonight... 


Mesoanalysis... 
19z analysis...visible satellite imagery shows sea breeze boundary 
pushing inland from Houston to Victoria. There is also a frontal 
boundary pushing through c Texas now through Waco/Temple areas. Visible 
satellite also shows areas of enhanced cumulus development from 
Columbus to Conroe with another area possibly along an old outflow 
boundary from Crockett to College Station and then near San 
Antonio. Water vapor imagery shows short wave trough moving 
through north c Texas and West Texas which has already initiated convection 
down along the Rio Grande. Convection along the out flow over c Texas 
and Hill Country looks to be getting some enhancement from 
associated lift. Satellite derived precipitation water values range from 
1.6 to 1.7 inches in the areas of enhanced convection. Storm Prediction Center 
mesoanalysis shows instability building up to around 3000 j/kg 
over the area with very little cin. Changes in cape/cin the last 3 
hours have been to increase cape and decrease cin so starting to see 
the airmass destabilize across the area. 


Think that convection should be initiating the next couple of 
hours with areas in the upper 80s already. Suspect that if precipitation 
water values were higher storms would be forming already. Recent 
trends in hrrr still develop convection over the area as do 12z 
WRF arw/nmm runs. Even Texas tech WRF is aggressive with 
thunderstorm development 21z Sat to 03z. Only conditions that may 
be keeping thunderstorms from forming is slightly lower moisture 
than expected and perhaps some weak ridging at 700mb. That said 
there is a cold pocket of -13c at 500mb over c Texas that may push 
over the area later this evening. Trough axis may be enough to 
weaken any middle level ridging. 


Once storms do form...thinking is that storm motions will be very 
slow. But hi res models seem to think a line of storms could form 
with a cold pool. The good news with this is that storms may push 
through the area and decrease the threat for heavy 
rainfall/flooding. Still need to watch because any storms that 
exceed rain rates of 2 inches an hour could still potentially 
cause flooding problems. In general any area that gets over 3 
inches quickly could have flooding problems. Should storms move 
slower the even storm with 1-2 inches an hour could cause problem 
if they persist for only 2-3 hours. For this reason we 
will keep the Flash Flood Watch going as is. 


Short term... 
frontal boundary should push off the coast Sunday with lower 
dewpoints forecast to move into the area. Models show precipitation water 
values dropping to under 1 inch for Monday. Precipitation water values 
could remain under 1.5 inches through the middle of the week. For 
now have continued to trim back rain chances. Upper low that was 
prognosticated to close off over la is now progressive with both the 
GFS/European model (ecmwf) so looks like northerly flow aloft will keep rain 
chances low. 


Long term... 
Thursday/Fri/Sat for the coming week both the GFS/European model (ecmwf) are in good 
agreement with upper level ridging building over Texas for the 
beginning of June. This should keep rain chances out of the 
forecast and allow for grounds to dry out. Maximum temperatures may reach the 
upper 80s to low 90s each day. Rain chances kept in the 10-20 
percent range.

&& 


Marine... 
relatively benign with winds around 5 knots at the moment and seas 
of 2 feet. This should prevail tonight but will have to watch the 
stysem coming down the Rio Grande and extending into the Austin area 
to make sure they don't turn east. If so then strong gusty winds 
could accompany the storms. Cold front should arrive near the coast 
around 4 am plus or minus a couple of hours. Northerly winds in the 
morning relax as another seabreeze forms. A little stronger 
northerly flow Sunday night may reach sustained near 10 knots. 
Onshore flow resumes by late Monday and continues until a second 
push of drier air arrives early Tuesday but this one is shorter 
lived. Wednesday is return flow and may finally see sustained 10-15 
knot southeast-south-southeast winds by Wednesday night. 


Tide levels one half foot to one foot above normal through tonight 
then should subside Sunday with onset of the more northerly winds.
