Severe Weather Alert Descriptions

 Flash Flood Watch  Statement as of 8:49 PM CDT on April 28, 2016


... Flash Flood Watch remains in effect from Friday afternoon
through Sunday morning...

The Flash Flood Watch continues for

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

* From Friday afternoon through Sunday morning

* unusually moist tropical air will stream into the region Friday
as southerly winds increase. An upper level jetstream will bring
a series of disturbances into the region and should help to
develop showers and thunderstorms Friday afternoon over the
western portions of the watch area then shifting eastward and
northward throughout the region Friday night and Saturday. The
ground is saturated and any storms with high rain rates will
lead to rapid runoff and flooding. The heaviest rainfall threat
should peak Friday night through Saturday afternoon. Additional
rainfall is possible after that and the ground will be saturated
and streams and bayous may already be swollen or flooding.
Widespread rainfall totals through the watch period will likely
average 2 to 4 inches with localized amounts of 5 to 8 inches.
Much of these amounts could come in only a few hours of heavy
rain. As we approach the watch period... confidence in timing
and location will likely improve the focus for where the heavy
rains will fall.

* Streets... bayous... streams and rivers will likely have the
greatest impacts from the heavy rainfall. Motorists and
persons with outdoor activities should stay abreast of the
latest forecasts and have contingency plans for when the heavy
rain arrives.

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 
1201 am CDT Friday Apr 29 2016 


Aviation... 
with the warm front north of kcll and kuts...expect MVFR 
conditions to develop by 09z over those sites which are not 
already lower than VFR at 06z. Nambufr model soundings suggest 
that the guidance is too low for ceilings for most sites. 
However...IFR conditions at kgls and kgls would suggest that IFR 
conditions could work inland to ksgr and khou. Good warm air and 
moist advection may be enough to also generate drizzle or light 
rain. 


On Friday...a consensus of the short-range models suggests that 
the main area of showers and thunderstorms will develop well 
inland. However...there are a variety of solutions to the 
coverage problem. There will be breezy surface conditions 
indicating very good moisture advection. Chances for showers may 
start earlier than indicated. The main area of showers and 
thunderstorms looks to develop northwest and west of the forecast 
area...then then work their way eastward toward the terminal sites 
during the late afternoon and evening. A few items that point to 
this solution are the GFS and ecwmf both forecasting a 250 mb 
divergent area more over central and North Texas during day on 
Friday. This area does not work its way into southeast Texas until the 
evening. The 500 mb level shortwave troughs also are not forecast 
by both models to arrive until the evening. Thus...tweaked the 
forecasts to have the main thunderstorm chances to arrive later 
than the previous forecast.

Previous discussion... /issued 847 PM CDT Thursday Apr 28 2016/ 


Discussion... 
a warm front has moved through southeast Texas and now extends from about 
Jackson MS to near Waco to near del Rio. A few showers developed 
along the front earlier this evening but have since dissipated. 
00z soundings reveal precipitable water values near 1.4 inches at crp and 1.8 
inches at lch. The lch sounding shows moisture from about 900-700 mb 
while the crp shows more of a cap at 850 mb and a much shallower 
moist layer. Can't rule out a few showers overnight but short term 
guidance is suggesting that precipitation doesn't really start developing 
until after 10z. Trimmed probability of precipitation back a little but still feel some 
rain showers/thunderstorms and rain are possible closest to the warm front over the extreme 
northern zones. Could get some streamer showers closer to the 
coast later tonight as well. Will also maintain fog in the weather 
grids. Min temperatures and sky grids look on track so no changes needed 
there. 43
