NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
337 PM CST Monday Mar 2 2015 


Discussion... 
frontal boundary has remained in the Gulf of Mexico today 
allowing for cool damp conditions most of the day. Temperatures have not 
risen much but with thin enough cloud cover a few areas have 
reached the upper 50s to low 60s along the coast. Areas from kcll 
to kuts remain in the 40s. Kcll has not reached the 50s since 
having a high of 50f on Feb 25. Before that it was Feb 22. Water 
vapor imagery does show strong short wave trough over the desert 
SW which should push into the c plains by 12z Tuesday. This should 
allow for surface cyclogenesis in the High Plains and for southerly 
winds to develop. Fronal boundary should move north as a warm 
front bringing back temperatures in the 70s and dewpoints in the 60s. 
Forecast will keep a chance of showers and maybe an isolated 
thunderstorm. Forecast sounding still show a decent cap and 
limited instability so an isolated storm maybe a stretch. 


The main forecast challenge will be the changes in the weatehr 
Wednesday into Thursday. Forecast models are in decent agreement with strong 
trough pulling through the plains Wednesday with an upper low over 
California moving east across Mexico and S rockies phasing with 
this system. A strong cold front is expected to push into the area 
Wednesday but the NAM/GFS/ECMWF all have different timing. Forecast 
leaned more on the faster GFS and even about 3 hours faster than 
that. There is good support for a faster frontal movement given 
the deep trough over the plains. The only problem is that the 
phasing trough may keep jet stream flow SW and help stall the 
front. That said...just looks like there will be a cold enough 
airmass to keep it pushing through. 


The Race is then on between freezing temperatures and precipitation falling for 
Wednesday night into Thursday. Synoptically jet stream becomes favorable 
with lift due to right entrance region positioned over much of c 
and East Texas. Frontogenetic lift increases in 850-700mb over the area. 
Model soundings at kcll/kuts show a nice mix of precipitation from 
rain/frzra to sleet. If the cold air deepens enough and 
saturates...could get more sleet to fall. Main areas of concern 
will be for College Station to Livingston northward. This also 
hinges on timing of freezing temperatures and if precipitation will be falling 
through that air. Precipitation is expected to decrease through the 
morning as lift exits the region and subsidence begins to take 
over. Ice/sleet amounts will be difficult to determine since there 
will be timing issues with the cold sub freezing air and precipitation 
falling into it. Issued a Special Weather Statement to highlight 
main thinking on what when and where with impacts. 


Extended forecast is still quite uncertain for the weekend and 
into early next week. GFS/European model (ecmwf) both bring another upper low 
towards Texas Saturday into Sunday. Forecast will keep some rain 
chances going to account for this wave but still lots of timing 
issues. Both models have run to run consistency but not with each 
other.

Marine... 
this break in the sea fog expected to be brief with the return of on- 
shore surface winds this evening/overnight. The limited/lowered visibili- 
ties with the fog should linger for most of tomorrow and Wednesday...even 
with the onshore winds strengthening/deepening out ahead of the next 
cold front. Models still bringing this front into the bays late Wednesday 
afternoon and into the coastal waters Wednesday evening. Tight gradient in the 
wake of the front will produce very strong/gusty north/NE winds for Wednesday 
night on through most of Thursday. Wind gusts may exceed gale force but 
the prognosticated sustained flow will likely keep US in the small craft ad- 
visory category for that time frame. 41
