NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1225 PM CDT Thursday Jul 24 2014 


Aviation... 
moist and unstable airmass across the area in combination with daytime 
heating and surface boundaries should allow for additional rain showers/thunderstorms and rain 
development this afternoon. Will carry thunderstorms in the vicinity for most of the 18z tafs 
south of iah. Expect decreasing coverage this evening with the loss 
of heating. With upper level ridging trying to build into the area 
from the northwest tomorrow...the area should see less rain showers/thunderstorms and rain 
coverage. For now...will just carry vcsh near the coast toward sunrise. 
If the ridge doesn't get strong enough...we might end up needing to 
carry some vcsh or thunderstorms in the vicinity further inland. 42 
&& 


Previous discussion... /issued 1040 am CDT Thursday Jul 24 2014/ 


Update... 
slow-moving showers and light rain affecting the western forecast 
area this morning...putting down between 1.5 to 2.5 inches locally 
over parts of Colorado...Austin and Waller counties. Although 
there will be isolated inland thunder...the majority of the storm 
clusters are offshore...located approximately 20 nm and beyond off 
Galveston Island. The noted upper height weakness current laying 
over the western Gulf Coast...with the 500 mb ridge centered over New 
Mexico...will be the pattern over the next 24 to 48 hours. Ample 
column moisture and unstable profiles suggest that chance probability of precipitation 
will linger on through the day...possible return again Friday. No 
discernible shortwave disturbance rounding the eastern periphery 
of the upper ridge...nor any near term foreseeable upstream outflow 
boundary as a trigger (as was case this morning)...will keep overnight 
into early Friday rain chances on the slight side. Early day sun 
up north may counter recently wettened ground in producing maximum 
temperatures in the mean middle 90s. 31 


Previous discussion... /issued 402 am CDT Thursday Jul 24 2014/ 


Discussion... 
the upper low that was over the Louisiana coast yesterday has 
sheared out early this morning...with the leftover trough 
stretching from eastern Louisiana to the middle Texas coast. A 
general northerly flow was in place aloft due to the weakening 
trough and an upper high centered over western Colorado and nm. The 
models generally build the high pressure ridge over eastern Texas 
and northern Louisiana Friday through Sunday...then then over southeast 
Texas on Monday as an upper trough begins to dig southward from the 
Great Lakes. As this trough pushes into the lower Mississippi 
Valley during the middle week period...the high will push westward 
into the Desert Southwest and return a northwesterly flow overhead 
the forecast area. 


The main problem for today concerns thunderstorm chances. The 
short term and high resolution models agree with the best rain 
chances over the southern half of the forecast area. Storm motion 
will again be generally from the northeast to southwest...while 
model forecast soundings also indicate the potential for gusty 
winds and heavy downpours in the stronger storms. Of note...the 
NAM bufr forecasts precipitable water/S from 1.8 in the northwest to near 2 inches 
toward the coast...while the afternoon sounding forecasts an 
inverted v profile below 850 mb and dcape values of 700 to 1100 
j/kg. 


Kept the isolated chances for thunderstorms in the forecast for 
Friday as the ecwmf in particular keeps the weakness aloft 
overhead and the GFS ensemble forecasts slight chances for rain. 
However...the main forecast challenge for Friday through Monday 
will be daytime high temperatures. Even though the ridge will 
build overhead...the guidance has backed off a bit on the very 
warm temperatures. Given the overall soil moisture content... 
slightly cooler than expected highs are likely. However...still 
expect highs of 96 to 98 across the central and western counties. 
The heat index will also be warmest over the Friday through 
Monday...with values ranging from 102 to 106 each afternoon. 


With the upper trough digging southward into the lower Mississippi 
Valley on Tuesday and Wednesday...both the GFS and European model (ecmwf) push a 
summertime cold front southward into east and southeast Texas. 
There is still some uncertainty on how far south the front will 
be...but for now it looks like both days will probably see a 
return of thunderstorm chances and slightly cooler daytime 
temperatures. 


Marine... 
do not expect much change in the forecast for the Upper Texas coast. 
Generally expect south to southwest winds through the end of the 
week and into the weekend. Winds may increase to moderate levels 
over the weekend but then decrease early next week as a frontal 
boundary approaches East Texas. Light to moderate winds will support 
mainly low seas for the next several days. No marine hazards are 
expected at this time. 39
