NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
948 PM CDT sun Sep 14 2014 


Discussion... 
high pressure was over southeast Texas this evening. Drier air was 
working its way in from the northeast and was helping to erode the 
cloud cover. The front which moved off the coast a couple of days 
ago should begin moving back toward land later tonight and Monday 
morning. As it does so...expect rain chances to begin increasing 
over the coastal waters overnight tonight and then over the 
coastal counties Monday morning. 


The current forecast is pretty much on track. Did tweak the cloud 
cover a bit for the update.

Discussion... 
00z taf discussion in aviation section. 


Aviation... 
surface ridge still extends into southeast Texas allowing for light winds. 
Isentropic lift over the front that kept moisture trapped and 
supporting MVFR ceilings has weakened. Visible satellite shows cloud cover 
eroding over the area so expect MVFR ceilings to give way to VFR 
through 01-02z. That opens the door for some possible patchy fog 
at some of the rural terminals. Could see some terminals with 
4-5sm visibility. Otherwise expect VFR ceilings. Light winds should continue 
tomorrow. Moisture may increase along the coast to allow for some 
rain showers/thunderstorms and rain but confidence fairly low.

Previous discussion... /issued 341 PM CDT sun Sep 14 2014/ 


Discussion... 
clouds have started to clear in our far northeastern zones this 
afternoon but mostly cloudy to overcast skies have remained across 
most of the area today. This again has allowed temperatures to be 
held down a bit. The surface high in association with this cooler 
air has quickly pulled off to the east today allowing the air 
mass to moderate. Winds will gradually veer tomorrow bringing 
more humid air back to the area. Rain chances will gradually start 
to come back tomorrow as the front washes out and upper level 
diffluence sets up overhead. Forecast soundings don't look great 
though with only marginal instability. Precipitable water values are forecasted 
to be around 1.80" with k index values around 30. The best chances 
of rain will be offshore in association with the higher moisture 
values and approaching wave. 


Models seem to be having difficulty with the weak tropical wave 
that was off the coast of Florida yesterday. On the water vapor 
the wave can clearly be seen approaching the Yucatan Peninsula. 
Both GFS and NAM seem to be out to lunch with the wave forecasted 
to currently be in the central Gulf. The Euro is one of the few 
models to have this feature farther south. Yesterday rain chances 
looked good Tuesday into Wednesday thanks to moisture streaming in 
from the wave. Now that the wave is farther south precipitable water values are 
not as encouraging as they were yesterday. 2.3" precipitable water values 
yesterday are now around 2.00". Upper level diffluence remains 
over the area Tuesday into Wednesday and there still exists 
northwest flow in the middle levels which should allow for upper 
level disturbances to cross the area. At the same time energy 
from Odile will start to be picked up in the upper level flow. The 
Euro and GFS both stream weak positive vorticity advection over the area Wednesday and 
Thursday from the system. This will allow rain chances to continue 
through the rest of the work week. 23 


Marine... 
expecting winds and seas to continue to come down as high pressure 
settles over the region. This afternoon's marine forecast package 
will call for light mainly east winds Monday through Wednesday and 
then winds a little more from the southeast (just a tad stronger) 
for the second half of the week. At this time... anticipate marine 
areas to be flag free for at least the next five to seven days. As 
for rain... be on the lookout for periods of showers/thunderstorms 
through at least the first half of the week as weak low pressure 
in the central Gulf of Mexico continues to edge westward toward the 
middle and Lower Texas coast. 42
