National Weather Service Houston/Galveston Texas 
618 am CDT Friday Oct 31 2014 


Discussion... 
see aviation for 12z taf issuance. 


&& 


Aviation... 
cold front currently just south of College Station this morning 
and heading to the south. The front will move off the coast this 
morning leaving clear and windy conditions in its wake. Khgx vwp 
this morning showing 25 knots winds just above the surface. These 
should quickly start to mix down as the sun rises. Surface high 
pressure will start to drift east Saturday allowing winds to veer 
to the east. VFR through the issuance. 23

Previous discussion... /issued 404 am CDT Friday Oct 31 2014/ 


Discussion... 
a weak disturbance pushing south ahead of a surface cold front has 
triggered scattered rain showers/thunderstorms and rain over mainly central Texas. The area of 
precipitation is clipping the western edge of southeast Texas. Most of the activity 
will either wane or be out of the County Warning Area by 12z so will not carry 
probability of precipitation this morning. At 3 am...a pre-frontal trough extended from 
Shreveport to College Station to Hondo. A cold front lagged a bit 
behind and extended from Texarkana to Waco to San Angelo. The 
front will continue to make rapid progress south this morning and 
should clear the coast between 12-15z. Dew points upstream are in the 
30's and this drier air mass will filter into the region today. Relative humidity 
values will plummet into the lower 20s by afternoon. Surface winds 
will also be on the rise so there are some concerns with elevated 
fire weather conditions later today. Temperatures are tricky today as cold air advection 
will compete with a relatively warm start. Surface high pressure will 
move toward the middle Mississippi Valley on Saturday and then push 
east on Sunday. Both Sat/Sun morning will be chilly with lows 
falling into the upper 30s over the NE zones each morning and 
low/middle 40s elsewhere except the coast where middle 50s are expected. 
As the high shifts east...onshore winds will return Saturday night 
and gradually strengthen as low pressure develops in the Lee of 
The Rockies. 


Things get muddled in a hurry for the new work week. 00z model 
runs continue to differ significantly with the 12z runs. Now the 
European model (ecmwf)/GFS both hold the upper level low to the west while a 
coastal trough develops. An approaching cold front will probably 
stall or slow significantly as the front becomes parallel to the 
upper flow. It is unclear at this time how far the front will make 
it into southeast Texas. The consensus between the GFS and European model (ecmwf) brings the 
front to a Crockett to Huntsville to Columbus line on Wednesday. 
With the upper low to the west and an active jetstream aloft...feel 
unsettled weather will continue for much of the new work week. 
Will carry probability of precipitation through next Friday and increased sky cover. There 
is some potential for heavy rain next week due to the slow 
movement of the system. Confidence is rather low due to model 
inconsistency. 43 


Marine... 


A cold front currently in central Texas will continue to push 
towards the south this morning and move off the coast midmorning. 
Behind the front offshore winds will gradually increase reaching 
scec criteria around 10 am and then advisory levels this afternoon. 
Have gone ahead and issued a scec for this morning and a Small Craft Advisory for 
this afternoon due to the strong pressure gradient forecasted. Seas 
will also begin to build and likely reach 7 feet by Saturday 
morning. Surface high pressure will then begin to pull east Saturday 
into Sunday allowing winds to gradually weaken and veer to the east. 
Onshore winds will return to the area quickly Sunday and increase in 
speed as the gradient tightens thanks to low pressure forming east 
of The Rockies. Onshore winds will approach Small Craft Advisory criteria again 
Sunday evening into Monday. 23 


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
