NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1045 am CDT Friday Oct 31 2014 


Update... 
morning forecast update... 


&& 


Discussion... 
cold front has pushed into the Gulf this morning with much drier 
air filtering into the region. Expect dewpoint temperatures to drop into 
the 40s with relative humidity in the afternoon near 25-30 percent. Winds will be 
gusty to around 20kts so there will be an elevated fire danger for 
the area mainly west and SW of Houston. Main forecast update did 
adjust cloud cover for ongoing trends as well as temperatures. Maximum temperatures 
may be a degree or two cooler across the area than previous 
forecast given cold advection and gusty winds. 


39 


&& 


Marine... 


Made some minor tweaks to the marine forecast with winds increasing 
started the Small Craft Advisory an hour earlier. Winds continue to blow pretty hard 
this afternoon and evening with winds in the profilers/models 
showing sustained winds around 20 knots gradually diminishing 
Saturday morning. For the Gulf waters extended the Small Craft Advisory to 15z but 
the nearshore waters may drop off sooner. 
45 


&& 


Aviation... 


Most of the area observation showing clear skies or some lingering cirrus from 
the mesoscale convective system moving through south Texas. Winds have been a little slower 
to come up but as temperatures near 70 degrees between 16-17z winds 
should ramp up abruptly with the gusty north winds. Winds do drop 
off tonight and veer to the northeast. 
45 


Fire weather... 


A strong cold front will move through the area this morning allowing 
cooler and drier conditions across the region. In our southwestern 
areas this afternoon minimum relative humidity values will be in the lower 20% 
range with winds approaching 15 kts. This in combination with a dry 
second half of October will lead to elevated fire weather 
conditions. 23
