NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
436 am CDT Sat Sep 20 2014 


Discussion... 
big change to the airmass over the region this morning. Drier air 
spreading into the region from the northeast stands out nicely on 
satellite and dewpoints lowering to 69 at Huntsville...74 even at 
gls. Rain chances today should mainly stretch from around Brenham 
to Liberty southward with isolated thunderstorms possible this 
afternoon primarily southwest of I-45+i-10. Temperatures rebound 
this weekend from our last few rain filled days with abundant 
cloud cover in the lower to middle 80s to the upper 80s to around 90 
today and a degree or two warmer on Sunday. Easterly flow should 
continue to dry out the region Sunday and shunt the moisture and 
rain chances to the Gulf waters and perhaps near Matagorda Bay 
area. Upper trough just west of Great Lakes will drop southeast 
and intensify dramatically pushing a front down into southeast 
Texas late Monday/Tuesday and this will lead to increased rain 
chances. Am a bit skeptical about the abundance of moisture that 
some of the models forecast to arrive with the boundary given the poor 
advection pattern in place in advance of the front so have limited 
the probability of precipitation to 20s and 30s north and east of Houston. Front pushes 
southward on Tuesday and should depart the area by Tuesday 
afternoon. Models are in good agreement through Wednesday and 
expect the rain chances to focus over the far coastal waters or 
deeper in the Gulf. Of course by Thursday the extended guidance 
diverges dramatically...arggg...with the handling of the upper 
ridging building into the Great Lakes region and the sharp 
troughing over the West Coast. Have in general favored the more 
reliable European model (ecmwf) solution which for southeast Texas maintains a drier regime 
through Wednesday through Saturday. Wednesday should be a chamber 
of Commerce day across the region...mostly sunny skies with 
humidity values falling to 35 percent across the north to 45 
percent through the Houston metropolitan area...bbq weather.

Marine... 
high pressure off to our east will help keep easterly 
winds in place through the weekend. Weekend mariners can expect 
slightly elevated sea heights due to the prolonged easterly fetch. A 
cold front will approach the area Monday before stalling and washing 
out near the coast. East winds will persist through next weekend and 
gradually strengthen middle week and beyond as the pressure gradient 
tightens. A persistent easterly fetch will allow tide levels to 
slowly increase through the week. 23
