 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 
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

Previous discussion... /issued 619 PM CDT Thursday Apr 28 2016/ 


Aviation... 
a warm front was working its way slowly northward through southeast Texas 
this evening. MVFR to IFR conditions have already developed at 23z 
and expect these conditions to become widespread by 05z. IFR looks 
likely after 09z. The models lift the conditions to VFR by midday 
on Friday. There is some disagreement between the model solutions 
for rain and thunder chances on Friday. Best consensus is late in 
the afternoon through the evening.

Previous discussion... /issued 326 PM CDT Thursday Apr 28 2016/ 


Discussion... 
Flash Flood Watch in effect for areas generally along and north 
of a line from Wharton to Houston to Groveton Friday afternoon 
through early Sunday morning. Heavy rainfall threat increasing 
for Friday afternoon through Saturday night. Saturated soils 
across the region will be incapable of absorbing the heavy 
rainfall. Intense rainfall rates will be likely during the watch 
period especially late Friday afternoon in the west expanding east 
and northward Friday night and Saturday which could directly 
impact the areas hardest hit by last weeks deluge. Rainfall rates 
of 3" per hour are within the realm of possibility given the 
abundant moisture and strong moisture transport into the system. 
Naefs ensembles painting a swath of 99th percentile or greater ivt 
across the region 00-12z Saturday. 


In the short term expect the warm front to lift northward the 
remainder of the afternoon and night - leading to mostly cloudy 
to cloudy skies with a warm and humid night. Marine observations 
continue to show dewpoints of 75 to 77 well south of the warm 
front which is near the I-10 corridor as of 18z. 


Rain chances increase after sunset in the northwest tonight with 
proximity of the warm front and subtle short wave moving through NE 
Mexico...rain rates shouldn't be high but can't rule out a 
thunderstorm or two. Friday gets more troublesome with model 
timing differences and initially was planning to issue the Flash 
Flood Watch to begin around 6 PM Friday but after seeing the high 
res arw and European model (ecmwf) have begun the Flash Flood Watch earlier to 
avoid missing the threat of the heavy rainfall starting earlier 
than currently expected. Both of those models allude to an mesoscale convective system 
developing and moving into the western areas Friday afternoon. 
Though confidence on those specifics isn't very high the 
confidence of heavy rainfall unfolding Friday night increases 
dramatically with a strong low level jet/massive moisture transport oriented 
through the region under an area of increasing diffluence. Think 
it is still too early to try to pinpoint any specific area but 
this pattern is very favorable for heavy rainfall. Soundings show 
a good deal of destabilization 00z Saturday through 18z Saturday 
and this will lead to an increase in the rainfall rates and 
increase the severe weather threat as well. Gusty winds and hail 
should be the main threats of severe...and as we saw with our 
event two days ago the wet ground and strong winds is a very 
dangerous combination for bringing down trees. 


At some point Saturday night or Sunday weak upper ridging occurs 
over southeast Texas with a weak Pacific front slowing and stalling (probably 
near the coast or just offshore) which should help to lessen the 
coverage of storms to the north but could focus storms more toward 
the coast. The stalled front remains a player in the weather 
Sunday and Monday before the next upper trough rotates through 
Monday morning-Tuesday morning...bringing another threat of 
widespread rainfall. This is going to strongly depend on how 
worked over the atmosphere gets in prior periods and recovery of 
ll moisture. By Tuesday night the consensus of the global models 
is a stronger push of cool air out into the Gulf and the region 
getting a much needed break from the rainfall Wednesday through 
Friday. 


45 


Marine... 
have raised caution flags for the 00-60 nm waters beginning at 
6 PM tonight in anticipation of strengthening southeast winds 
and building seas during the overnight hours. Sea heights should 
eventually reach 7 feet or more across portions of the waters... 
and we'll likely need small craft advisories. This building surf 
will also lead to an increasing threat for rip currents. Highest 
tide levels should come during high tide times on Friday and 
Saturday...especially close to the Highway 87 and 124 connection 
near the Bolivar Peninsula. Mariners should still plan on periods 
of showers and thunderstorms over the weekend as a slow moving cold 
front takes its time moving off the coast Sunday or Sunday night. 
East to northeast winds are anticipated for the first half of next 
week. 42
