NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1142 PM CDT Monday Sep 1 2014 




Aviation... 
so far the showers have been getting to the coastline and 
dissipating but the next few may get further inland. Deeper 
moisture still over the Gulf waters but it is coming this way. 
Changes to previous tafs are minor...delayed the onset of the MVFR 
ceilings by an hour or two but still roughly 08-11z. Showers should 
spread inland to hou/iah hubs by 12-15z and then with the 
increasing instability and loss of the cap expect rain showers to 
transition to rain showers/thunderstorms and rain 16-18z. Storms should move at 15 knots or 
so can't rule out a hit at one of the airports but at least it 
should be relatively short lived. Moisture axis shifts inland and 
by early evening the storms should be out of the terminals and 
with less coverage overnight Tuesday night thanks to drier air and 
more subsidence.

Previous discussion... /issued 1014 PM CDT Monday Sep 1 2014/ 


Discussion... 
seeing some activity trying to move onshore this evening with a 
bit more noted over the coastal waters moving in this direction 
than the previous evening. Only minor tweaks planned for the up- 
date as a quick peek at incoming models/other short-range forecasts 
remain rather insistent on at least scattered coverage for tomorrow. 


For the marine forecast...have increased winds/extended scec as per 
ongoing trends. 41 


Previous discussion... /issued 758 PM CDT Monday Sep 1 2014/ 


Aviation... 
storms inland have nearly all dissipated but the Gulf is more 
active and GOES sounder shows 2.1-2.2" precipitable water marching into the the 
coastal waters where coincidentally the showers have been 
increasing in coverage. These should continue to move toward the 
coast but will be fighting the subsidence near the coast at least 
for a few more hours. By 10 PM to midnight expect that some of the 
showers should creep into the coastal areas. Have vcsh for gls 
after midnight. Increasing moisture should lead to a band of scattered 
to broken ceilings spreading across the area overnight and mainly after 
midnight. Do expect some IFR ceilings at cxo and may come close at 
uts/cll but don't expect the fog or dense fog that happened early 
this morning. Showers and thunderstorms should be scattered across 
the region Tuesday and for now have vicinity rain showers/thunderstorms and rain and tempo 
conditions for the hou/iah hubs between 16-21z where the best 
chances lie for the combination of moisture/lift/instability. 
Drier air should flow back into the area Tuesday night/Wednesday 
and less coverage. 45 


Climate... 
the climatologic Summer defined as June...July and August has 
come to an end and there were no 100 degree days recorded at any 
of the 4 first order climate sites. Houston has not had a Summer 
free of 100 degree days since since 1997 and College Station has 
not achieved this feat since 2004. The average temperature for the Summer 
was also cooler than normal for areas north of I-10 and a bit 
warmer than normal for areas south of of I-10. 43
