NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
304 PM CDT Sat Aug 30 2014 


Discussion... 
showers and thunderstorms are beginning to redevelop over the area 
as temperatures approach 90 degrees. Coverage will likely to 
continue to increase through around 4 PM and then begin to 
dissipate with the loss of heating. The bulk of the evening should 
be dry. Precipitable water values surge back into the area after 06z and a 
combination of speed convergence...an upper level weakness over 
south Texas and a strong vorticity lobe will allow another round of 
rain showers/thunderstorms and rain to develop after 09z and persist through about 15z. The 
speed convergence will wane Sun morning and the vorticity lobe moves 
east so am expecting the precipitation to end around 15z. That said...heating 
during the afternoon will still allow some scattered rain showers/thunderstorms and rain to redevelop 
in the afternoon. Precipitable water values drop a bit on Monday but still peak near 
2.00 inches in the afternoon which still looks sufficient for diurnally 
driven shra/tsra. 


On Tuesday...an easterly wave will approach the Mexican coast and the 
wave will bring another surge of moisture into Texas. Forecast soundings 
show precipitable water values above 2.00 inches with k index values in the middle 
30s. Convective temperatures are considerably lower so temperatures will only 
need to reach the middle 80s for convection to develop. Although the 
wave will continue to weaken and move away from Texas...there 
should be enough of a weakness to still allow rain showers/thunderstorms and rain to develop 
on Wednesday. Convective temperatures on Wednesday will be warmer and 
values near 90 degrees will be required for convection to 
initiate. Upper level ridging begins to reassert itself over the 
Southern Plains toward the end of the week. Rain chances should 
begin to decrease as subsidence increases but precipitable water values remain 
between 1.7 and 1.9 inches so isolated rain showers still look possible 
through next weekend. 43 


&& 


Marine... 
this unsettled weather pattern will linger on through early next 
week...or as long as a trough of low pressure resides over the 
western Gulf. Frequent periods of light rain with embedded moderate 
showers and the occasional thunderstorm passage. Winds and seas 
will be churned up in and around vicinity maritime storms. Onshore 
winds will generally be under 15 knots with lower seas through 
Monday. A tighter pressure gradient...or possibly Bay of Campeche 
lowering pressures due to a tropical disturbance...may strengthen 
winds/seas back to scec conditions late Monday through Tuesday. 31
