NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1203 am CDT Sat Sep 5 2015 


Discussion... 
updated aviation section. 


&& 


Aviation... 
latest satellite imagery showing clear sky across the area with no 
sign of any showers across the area. Question for the overnight is 
whether there will be any fog or stratus development and for 
Saturday what kind of coverage well see from showers. Latest runs 
of radpid refresh and high res rapid refresh are a little wetter 
than available models. Model soundings show some subtle differences 
with maybe a tad less cape Saturday. Bottom line think we will see 
development again Saturday...much as today...but with slightly 
less coverage. Have written tafs with vcsh for most likely 
windows. May need to hit harder if radar trends show cell 
development overnight. Also...only mention of fog are the more 
favored locations...cxo and lbx...as occurred last night. Have 
also included some scattered stratus inland sites. 46 


&& 


Previous discussion... /issued / 


Discussion... 
all of today's showers and thunderstorms are gone. Have updated the 
forecast package this evening with just some very minor first period 
adjustments. The rest of the forecast looks good. 42 


Previous discussion... 


Discussion... 
updated aviation discussion. 


Aviation... 
showers have diminished rapidly over the area over the past hour. 
As clouds also diminish expect sky clear to sct040 for most of the night 
from here on out. There is the possibility of at least scattered 
stratus and patchy fog mainly inland locations. Have kept fog 
mention at the usual locations...lbx and cxo. Tomorrow think will 
once again have shower development first at the coast in the 
morning...then farther inland during the afternoon. Not sure about 
coverage though as NAM soundings show somewhat less instability. 
However as pointed out by previous discussion precipitable waters 
quite high especially in nam12. Will keep mention of vcsh most 
spots to account for the development but with possibly more 
limited coverage. 


Previous discussion... 


Discussion... 
scattered showers continue to develop and move over southeast Texas. 
Precipitable water values remain around 2.00 inches and although rainfall totals 
today have been light...coverage has been rather extensive. The 
nam12 initialized best and verified the best today with it's 
likely probability of precipitation. The nam12 is again the most aggressive with moisture 
on Saturday with precipitable water values near 2.00 inches. Forecast soundings show a 
saturated layer between 900-800 mb with dry air above 700 mb. 
Moisture levels again look sufficient for 30/40 percent coverage. 
Upper level ridging tries to build into southeast Texas Sat/sun but it looks 
like the ridge never quite gets here and is displaced to the west-northwest 
of southeast Texas. An upper level low over the northern Gulf Coast will 
also slowly drift west. Precipitable water values on Sunday drop a bit but are 
still between 1.80 and 2.00 which is more than enough to generate 
scattered showers. Convective temperatures on Sunday are higher so in 
theory...coverage should be a bit less. Will maintain 20/30 probability of precipitation 
for now. If going to the beach over the weekend...slightly warmer 
temperatures coupled with higher humidity will yield heat index values 
between 102 and 106 degrees. Its not advisory criteria but still 
plenty oppressive for this time of year. 


Things are a bit more interesting on Labor Day. The upper low 
over the northern Gulf shifts further west and the upper ridge 
over North Texas becomes stretched from NE to SW. The upper flow 
over southeast Texas will become NE and this will allow a disturbance 
rotating around the upper low to approach southeast Texas in the afternoon. Precipitable water 
values will once again exceed 2.00 inches in the afternoon with forecast 
soundings showing a saturated layer between 850-700 mb. The 
disturbance coupled with higher moisture and daytime heating 
should again allow for scattered shra/tsra. Jet dynamics not the 
best on Monday as southeast Texas looks like it'll lie in the subsident 
region of the jet. 


Precipitable water values lower Tuesday/Wednesday and rain chances are expected to drop. 
Temperatures will be near or just slightly warmer than normal. The 
rainy weather returns again as early as Thursday as a shortwave moves 
into the region. The European model (ecmwf) is more aggressive with upper level 
energy and moisture. The GFS is about a day slower but both models 
eventually carve out a fairly deep long wave trough with the base 
of the trough over south Texas. There are some timing differences 
with the European model (ecmwf) holding the base of the trough over Texas and 
leading to some significant rainfall potential while the GFS is a 
bit more progressive and its trough is not as sharply defined. 
Either way...it looks like Friday-Sat of next week will be wet with 
some potential for heavy rainfall amounts. 43 


Marine... 
the general weather pattern over the Holiday weekend will be fairly 
benign as eastern high pressure slowly expands westward and 
influences local maritime conditions. Scattered early day 
showers will still occur with isolated stronger cells lowering 
visibilities within heavy rain...a very slight chance of a storm 
through Labor Day. Average winds will be light onshore over near 2 
foot seas. A weak disturbance moving out of Louisiana Labor Day may 
increase early week precipitation chances. 31
