Update... 
canceled part of the Flash Flood Watch and adjusted probability of precipitation for the 
morning.

will cancel western parts of the Flash Flood Watch and adjust probability of precipitation 
lower over the west for this morning. New zones out shortly. 43

Discussion... 
see the 12z aviation discussion below.

Aviation... 
the leading edge of the diminishing squall line was located from 
kuts to the Houston metropolitan sites to klbx at 1130z. Expect these to 
clear through the sites between 12z and 1230z...and then kgls by 
13z. Rain occurring in the trailing cold pool should last through 
middle morning at the latest. The rap13 model did a decent job with 
the system. The model keeps the potential for thunderstorms and rain at kgls and 
klbx through midday and the potential for redevelopment later 
this afternoon over the other inland sites. VFR expected tonight 
but there is an outside chance for MVFR conditions to develop. 
Next best chances for rain and thunderstorms will be Saturday 
afternoon as a frontal boundary sinks southward of the Red River 
valley.

Previous discussion... /issued 420 am CDT Friday may 29 2015/ 


Discussion... 
feel a Flash Flood Watch is warranted with the slow moving 
boundary and training of storms. Rainfall rates are not that 
impressive but concerned that training will yield some higher 
totals. The potential for flash flooding exists this morning. The 
watch will expire at noon. 


At 3 am...an outflow boundary was approaching southeast Texas with scattered 
to numerous rain showers/thunderstorms and rain moving across the western zones. 1-2 inches 
of rain has already fallen across parts of Colorado and Washington 
counties. The outflow boundarys eastward movement has slowed but 
still expect it to push east-southeast and cross all of southeast Texas by 10-11 am. 
That said...cloud tops are warming and the cold pool is losing its 
punch and have some concern that the boundary could stall over the 
area and serve as a focus for afternoon convection. Not sure how this 
will all play out. Short term guidance has performed well 
overnight but they diverge with what happens this afternoon. The rap 
has widespread development over all of the area...while the hrrr 
keeps things quiet this afternoon and matches up well with the Texas 
tech WRF. The nmm keeps things quiet with a cluster of storms 
developing this evening while the arw matches up better with the 
rap. Both the GFS/NAM have precipitable water values near 1.80 inches this afternoon 
with no capping and convective temperatures in the lower 80s. Feel once 
the outflow boundary reaches the coast...subsidence in its wake 
will keep things quiet for much of the afternoon with some 
redevelopment very late in the afternoon. Much depends on whether the 
outflow reaches the coast or hangs up across southeast Texas. 


Saturday still looks to be the wettest day of the weekend. Precipitable water 
values remain around 1.80 inches and upper level winds remain 
broadly divergent. A weak cold front will enter southeast Texas and cross 
the area Saturday night and clear the coast early Sunday. The 
front will serve as a low level focus for additional shra/tsra. 
Could get some training on Saturday with the front so the 
potential for locally heavy rain is possible. Rain showers/thunderstorms and rain will 
continue Sat night with precipitable water values between 1.7-1.8 inches. Drier air 
will work into southeast Texas on Sunday in the wake of the front with precipitable water 
values falling to 1.6 inches by 18z and 1.4 inches by 00z. Upper 
level winds become confluent by 00z so feel rain chances will 
remain high in the morning with considerably drier conditions 
developing from north to south in the afternoon. Precipitable water values on Monday 
are prognosticated to fall below an inch so it looks like a long awaited 
drying trend will begin next week. 


Next week...southeast Texas will lie between a developing upper ridge over 
West Texas and an upper level trough over the eastern U.S..can't rule 
out isolated to scattered rain showers/thunderstorms and rain but the overall trend for next 
week looks drier with seasonal temperatures. 43 


Marine... 
the low-level jet feeding into the squall line moving from The Hill 
Country to southeast Texas was mixing down and keeping winds at 
caution criteria early this morning. The model consensus is for the 
winds to gradually diminish today and Saturday. If another line of 
storms develop Friday night or Saturday...winds could become higher 
than forecast over the Gulf waters and bays. However...with a cold 
front moving into southeast Texas...a relaxed surface pressure 
gradient should lead to diminished winds as forecast by the models. 
Conditions are expected to improve for next week starting on Sunday.
