Aviation... 
NAM 12 and the GFS not in the best agreement again this morning. 
The NAM 12 has precipitable water values surging to 2.3 inches this afternoon while the 
GFS is around 1.90 inches. The latest hrrr seems to support the 
NAM so leaned in that direction. Have added vcsh for southern taf 
sites including kiah. Precipitation should end between 23-01z. VFR conds 
expected today and tonight outside of any convection. 43

Previous discussion... /issued 400 am CDT Wednesday Aug 5 2015/ 


Discussion... 
early morning water vapor imagery depicts a compact shortwave 
trough moving across the Central Plains... with broad ridging in 
place over the southwestern Continental U.S. And troughing across the east. 
The extremely moist airmass that moved across the region yesterday 
was seen pushing into northeast Texas per GOES sounder imagery 
this morning. Precipitable water values across the region ranged 
from 2-2.2 inches over Crockett/Trinity/Polk counties to 1.5 
inches around Matagorda Bay... with slightly higher precipitable waters  around 
1.7 to 1.9 inches just offshore. 


For today... southerly winds will again advect the higher 
moisture air over the Gulf into the region. This will provide 
enough moisture for isolated showers and thunderstorms to develop 
along the sea breeze as it pushes inland late morning through late 
afternoon. Carrying the highest chances /20 probability of precipitation/ along and south 
of the Interstate 10 corridor... but cannot rule out a stray cell 
or two pushing north of that area. Peak heat index values 
yesterday topped out at 108 at Galveston and with similar 
temperatures and low level moisture in place across the region 
today... anticipate heat index values to be near yesterday/S and 
again below heat advisory criteria. However... will be issuing a 
Special Weather Statement to highlight the heat for the remainder 
of the week and into the weekend. 


Loss of daytime heating will prevent sea breeze shower and 
thunderstorm activity from making it too far into the evening 
hours... but will need to continue to watch the evolution of the 
shortwave over the Central Plains. The NCEP 4 km WRF actually 
brings a thin line of thunderstorms tonight into the Piney Woods 
region as this shortwave dives towards the lower Mississippi River 
tonight. This model is initialized from the 40 km NAM... which has 
consistently been an outlier with the southernmost trajectory for 
this shortwave over the past few runs. 00z guidance /including the 
NAM/ did not initialize too terribly with the placement of this 
shortwave. However... given that this solution is an outlier and 
the majority of guidance keeps the shortwave too far north of the 
region to raise any real concerns for rain chances this evening... 
keeping the forecast dry for now. Otherwise... another warm and 
quiet night expected for the region. 


The upper ridge over the southwestern Continental U.S. Will continue to 
shift eastward over the next 24 hours... centering over eastern 
nm/West Texas on Thursday. Increasing heights aloft will serve to 
increase temperatures across the region with heat advisories 
potentially needed as early as Thursday. By the weekend... the 
upper ridge Parks itself over north/northeast Texas and prolongs 
the heat with inland temperatures rising into the low 100s this 
weekend. Those with outdoor plans this weekend will want to take 
extreme caution to prevent heat illnesses. Looking ahead to next 
week... medium range guidance does attempt to bring a frontal 
system out of the Great Plains with the Promise for low rain 
chances by the middle of next week. 


Huffman 


Marine... 
high pressure over the eastern Gulf and lower pressure over the 
Southern Plains will maintain a light to moderate onshore flow 
through the weekend. There will be subtle diurnal variations with 
slightly stronger winds at night and a brief S-SW component to the 
direction each morning. 43
