NWS Forecaster Discussion




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


Discussion... 
radar is showing considerably less precipitation than the past few 
days. Precipitable water values have fallen to around 1.90 inches this afternoon. 
Slightly higher 500 mb heights inducing a bit more subsidence is 
probably limiting area coverage. Surface dew points did not mix out this 
morning and heat index values peaked near 105 degrees at a few 
locations. Moisture is prognosticated to increase again late tonight into 
Tuesday and precipitable water values are prognosticated to reach 2.10 inches. Convective 
temperatures should remain in the upper 80s. The wave over the SW Gulf 
will move toward the Mexican coast and this feature should provide 
a subtle increase in lift. TPC has just upgraded this system to dew point 
#5. Dew point #5 will remain a weak system and make landfall late 
Tuesday night over northern Mexico. This system will have little 
impact on southeast Texas other than an increase in swells over the offshore 
waters. 


Moisture levels remain between 1.8-1.9 inches through the end of 
the week. Convective temperatures slowly warm but 500 mb heights remain 
relatively unchanged through the end of the week. Feel widely 
scattered rain showers/thunderstorms and rain will persist through Friday. Don't really see 
any features that would either enhance or diminish rain chances so 
will leave the current forecast as is (low end chance pops). Not much 
change is expected next weekend. Both the GFS and European model (ecmwf) bring a 
weak front into the state but the upper flow pattern doesn't look 
all that favorable for a front to move this far south. Will 
continue to advertise mainly diurnally driven shra/tsra. 43 


&& 


Climate... 
the climotologic 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

Marine... 
a Bay of Campeche tropical disturbance will aid in pulling in 
a higher central Gulf swell into the Upper Texas coastal waters 
through middle week. Another foot or two added onto already 3 to 4 foot 
wave heights...with the highest seas of around 7 feet occurring over 
the far (primarily western) offshore waters. Periods of showers with 
isolated storms along this disturbance's northern periphery may 
affect the local waters over the next few days. Southeasterlies will 
be around...or slightly exceed...small craft caution criteria 
through Wednesday. 31
