NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
408 am CDT Tuesday Sep 30 2014 


Discussion... 
weak high pressure aloft will give way to an approaching upper 
level trough on Thursday and early Friday. The GFS and European model (ecmwf) 
differ a bit on its strength but are close in timing. Both models 
push an associated cold front through southeast Texas Thursday night and 
off the coast Friday morning after sunrise. 


The main challenges for today through Thursday will be daytime 
temperatures. Guidance suggests highs each day will reach either 
to around 90 or into the lower 90s over the inland areas. Right 
now the warmest day looks to be Thursday. Moisture and warm air 
advection plus seabreeze activity may lead to isolated convection 
each day. 


Over the past couple of days...both the GFS and European model (ecmwf) have 
consistently brought the front off the coast around 7 am on 
Friday. The 00z runs continued this timing. The quantitative precipitation forecast fields for 
both models provide good coverage Thursday night and early Friday 
morning ahead of the front. For now do not think there will much 
of a chance for severe storms as the best dynamics and instability 
will be to the north. However...cannot rule out an isolated strong 
storm and will mention the possibility in the hazardous weather 
outlook. 


Clearing conditions will follow the front on Friday. High pressure 
then builds overhead for most of the weekend with onshore winds 
returning by late Sunday. Daytime temperatures behind the front 
look to be quite pleasant with highs reaching only in the lower to 
middle 80s on Friday and Saturday. The return flow on Sunday and 
Monday will lead to a warming trend with increasing humidity.

Marine... 
light easterly winds should become more southerly tonight into 
Wednesday with low seas. Southerly winds increase Wednesday night into 
Thursday as a cold front approaches the area. The stronger southerly 
winds may build seas slightly into Friday. The cold front should push 
off the coast during the day Friday and shift winds to the 
north/northeast. NE winds increase Friday night into Sat with 
building seas. Caution flags will likely be needed for conditions 
behind the front. Advisories cannot be ruled out but latest 
forecasts have winds below advisory criteria. Winds should 
decrease late Saturday and turn back to the southeast on Sunday.
