NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1026 am CDT Thursday Oct 2 2014 


Update... 
see discussion for morning update. 


&& 


Discussion... 
for this afternoon expect warm and muggy conditions with a chance 
of showers and thunderstorms. Current 12z 700 mb analysis shows a 
weak boundary across our zones with slightly better moisture to 
the east. Flow is also broadly convergent across out area at 700. 
At 850 mb temperatures have warmed around another degree or two 
compared to yesterday at this time. Winds have also started to 
increase at 850 thanks to a tighter gradient. This will allow for 
two things. First turbulent mixing has allowed temperatures to 
quickly warm this morning. It will also be gusty today thanks to 
850 winds approaching 30kts. Hgx vwp showing winds 20 to 25kts 
just above the surface. These higher winds have already started to 
mix down as seen on surface observation. Due to the mentioned above have 
increased maximum temperatures slightly for today. Rain also looks 
possible today and will take the form as scattered streamer 
showers and thunderstorms ahead of the front. GFS forecast 
soundings seem to be off this morning when compared to current 
observed amdar soundings. Amdar soundings show the warm layer 
between 850 and 700 but with deep low level moisture showers have 
already started to pop up. Convective temperatures are also only 
in the middle 80s. 


Regarding tonights into early Friday mornings front... have also 
moved higher probability of precipitation up a bit in timing thanks to latest high res 
models. Seems like line of showers and thunderstorms should be 
approaching College Station between 6 and 9 PM while reaching the 
Houston metropolitan around midnight tonight. We will continue to adjust 
the timing once all of the 12 z models come in this afternoon. New 
zones out shortly. 23

Discussion... 
12z taf discussion in aviation section. 


Aviation... 
MVFR ceilings cover most of the terminals this morning with some 
limited visibility at a few sites. Ceilings become VFR closer to the 
coast. There have also been a few rain showers passing by so will keep 
vcsh in most tafs through 15z. 


Main concern will be squall line and cold front pushing through 
the area tonight. Basic timing...kcll/kuts around 00z-03z with 
kcxo at 01z-04z. Expect line to reach kiah/khou/ksgr around 03z- 
06z but line of storms could be weakening as it pushes south. 
Largely depends on instability and any capping to overcome. Storms 
should then reach the coast around 05-09z for klbx/kgls. Timing 
based on combination of hi-res WRF solutions.

Previous discussion... /issued 434 am CDT Thursday Oct 2 2014/ 


Discussion... 
early this morning an upper level trough was moving across The 
Rockies into the plains with a cold front moving into the Texas 
Panhandle. An upper level ridge was situated across the Gulf of 
Mexico into south Texas. The NAM...GFS...and European model (ecmwf) all push the 
upper trough through the plains today and tonight with the cold 
front moving into southeast Texas around midnight and off the coast by 
around sunrise. 


The main concerns ahead of the frontal passage are rainfall 
coverage and strength of storms. The nambufr and gfsbufr forecast 
soundings show a warm nose persisting over about the southern 
third of the forecast area until about the time of the frontal 
passage. Some of the high resolution models keep the line of 
storms intact as the front moves across southeast Texas. However...the nam12 
is suggesting that the intensity of the line will diminish as it 
approaches the Interstate 10 corridor. For now will keep likely 
probability of precipitation in place ahead of the front. Rainfall amounts will likely by 
under 1 inch. Although there is a possibility for isolated strong 
storms to develop ahead of the front...a consensus of the models 
indicates isolated strong storms are possible mainly during the 
evening over the northern half of the area as the right-front 
quadrant of the upper level jet moves overhead. 


A pleasant weekend is in store following the frontal passage. 
Return flow off the Gulf will aid in a return to slight chances 
for rain by around Tuesday.

Marine... 
moderate southerly winds should continue today as a cold front 
approaches the region. The cold front should reach the Upper Texas 
coast Friday morning and through the offshore waters by noon Friday. 
Winds should shift to the north to northeast behind the front Friday 
afternoon. The northeast wind should increase in the offshore waters 
Friday night into Sat allowing seas to build. Caution or even advisory 
flags may be needed during this time. Winds and seas decrease into 
Sunday as high pressure moves east. This allows for southeast winds 
again for early next week.
