NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1225 PM CDT Wednesday Oct 1 2014 


Aviation... 
could see some rain showers/thunderstorms and rain development this afternoon...but expect the 
best concentration of activity to be east of a gls-iah-uts line. Will 
carry vcsh for current activity and amend this afternoon if any thunderstorms and rain 
develop in/around taf sites. Overnight...there should be another chance 
of mainly MVFR ceilings and visibilities at inland sites. IFR/LIFR levels 
along with some rain showers could develop too. The area should see slightly 
quicker lifting of the morning low stuff tomorrow morning due to the 
development of slightly stronger south winds. 


Cold front is still on schedule to move through southeast Texas Thursday 
night and Friday morning. Current thinking has the boundary and wind 
shift moving through the cll area 05z-07z (midnight-2am)...the iah area 
08z-10z (2am-4am)...and the gls area 10z-12z (5am-7am). Expect to see 
rain showers/thunderstorms and rain move through the area in association with the front. 42

Update... 
see discussion for morning update. 


Discussion... 
fog has quickly burned off this morning with partly cloudy to 
mostly cloudy skies across the area. Temperatures will again be 
around 90 degrees inland today ahead of the next cold front. 
Southeast Texas also falls in between very moist air to the east 
with drier middle level air to the west. Klch sounding this morning 
showing precipitable waters  at 2.25" while kcrp sounding showing a 1.60" precipitable water 
with considerable dry air at and above 700mb. Current forecast 
looks to have most of this covered. Only made minor tweaks to pop 
and maximum T grids. 23 


Previous discussion... /issued 649 am CDT Wednesday Oct 1 2014/ 


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


Aviation... 
there are a couple of aviation concerns this morning. First there 
are low stratus clouds and fog which have led to periods of 
MVFR/IFR ceilings. Look for ceilings to improve once mixing occurs after 
sun rise. This will likely happen around 15-16z today and should 
see VFR ceilings after that through the afternoon. 


Second there is still some convection possible with showers 
already impacting areas east of a khou/kiah/kcxo line. Will carry 
vcsh for a few of the Houston and surrounding terminals. Main 
moisture axis remains east through the Sabine River basin and 
several mesoscale models support rain showers/thunderstorms and rain in these areas. Think 
if any thunderstorms and rain do develop it will be east of these terminals. 


Finally look for a similar pattern for Thursday morning. Have added 
taf lines to cover ceilings in the MVFR/IFR categories with possibly a 
few showers impacting the area. Do not see quite as much fog as 
winds should be closer to 5kts overnight.

Update... 
sending out an update to include isolated probability of precipitation farther inland.

Previous discussion... /issued 347 am CDT Wednesday Oct 1 2014/ 


Discussion... 
a weak warm front was moving inland early this morning. The best 
moisture axis was just east of the forecast area over the coastal 
waters south...east...and inland of the Sabine. The main upper 
level ridge was well to the south over the southern Gulf into 
Mexico. 


The models are fairly consistent in deepening the upper level 
trough over The Rockies as it pushes into the plains later today 
through Thursday. They do differ on the strength of the trough as 
it moves into Texas Thursday afternoon and night. A consensus 
keeps the best lift...dynamics...and instability over the northern 
part of the state and the Southern Plains. However...southeast Texas should 
experience a period of rain and thunderstorms as the southern end 
of the trough and an associated cold front pushes across the 
forecast area. 


Good warm air and moisture advection will lead to isolated to 
scattered convection today into early Thursday. Widespread rain 
and thunderstorms will then occur ahead of the front Thursday 
night. The GFS and European model (ecmwf) still are consistent in pushing the cold 
front into the northwestern set of counties after midnight...and 
then off the coast around or shortly after sunrise. Isolated 
strong storms are possible with the main threat gusty winds and 
minor flooding due to locally heavy downpours. For the most part 
the models are forecasting the storms to move quickly enough to 
keep the quantitative precipitation forecast under 1 inch for the event. 


After the front moves through a couple of cool and dry autumn 
days are in store for southeast Texas. Moisture return off of the Gulf 
will begin either late Sunday or early Monday. 


40 


Marine... 
southeast winds have developed this morning as low pressure 
continues to develop in the plains. Southerly winds today and 
Thursday will support gradually building seas approaching moderate 
levels. A cold front should push off the Upper Texas coast from late 
Friday morning through the evening hours. A line of storms may be 
possible with front as it pushes offshore. Strong northeast winds 
may develop behind the front in the offshore waters Friday night into 
Saturday morning. Small craft advisories may be needed during this 
time for 20 knot winds and seas building to near 7 feet. These 
conditions should quickly weaken late Saturday as high pressure 
moves east of the area. Southeast winds may develop later on 
Sunday.
