Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:39 am CDT on August 20, 2014


... High heat index values across southeast Texas this afternoon...

The combination of warm temperatures and high dew points will produce
afternoon heat index values of 100 and 110 degrees this afternoon
across much of southeast Texas. The hottest conditions are
expected mainly between 1 PM and 6 PM CDT.

Take extra precautions if you work or spend time outside. If possible...
slow down... reduce... or reschedule strenuous outdoor activities until
the coolest part of the day. Wear light weight... loose fitting... and
light colored clothing to reflect heat and sunlight. Drink plenty of
water. Avoid any alcoholic and caffeinated beverages.

Young children... disabled adults and pets should never be left unattended
in vehicles under any circumstances. Car interiors on hot Summer days
can reach lethal temperatures in a matter of minutes.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
618 am CDT Wednesday Aug 20 2014 


Discussion... 
see 12z aviation discussion. 


&& 


Aviation... 
high precipitable water values will surge into southeast Texas today with values reaching 
2.00 inches. Convective temperatures are in the lower 90s so feel 
rain showers/thunderstorms and rain will once again redevelop with a bit of heating. Leaned 
a bit toward a rap/hrrr blend for precipitation coverage and the nam12 
for winds. Convection should wane quickly tonight with the loss of 
heating. The pressure gradient is rather tight so it'll be breezy 
at times. MVFR fog possible early this morning and again Thursday 
morning. 43

Previous discussion... /issued 405 am CDT Wednesday Aug 20 2014/ 


Discussion... 
low light satellite showing mostly cirrus hanging around tonight 
with breaks appearing across the area. 250 mb hand analysis for 0z 
today shows southeast Texas again in diffluent flow thanks to 
anticyclonic flow to our southwest in Mexico along with a weak 
shear axis just to the east of southeast Texas. At 500 mb a 
shortwave was analyzed that is forecasted to shear out and move 
into the Dallas/ Fort Worth area this afternoon. Current precipitable water 
values are around 1.40" inland with precipitable waters  near 2.00" over the 
waters (according to GOES sounder). 


Another tricky forecast this afternoon as many models showing 
conflicting data. In general... models do agree on bringing the 
2.00"+ precipitable water air into the area this afternoon and weak positive vorticity advection moving 
over this afternoon. GFS forecast soundings aren't extremely 
supportive for rain. Precipitable waters  for kcll are 1.87" with a k index of 
30. The NAM forecast soundings on the other hand do support rain. 
For kcll the NAM is forecasting a 1.99" precipitable water with a k index of 37. 
Ironically the GFS precipitation field shows more rain than the NAM. The 
Omega fields for the NAM do show lift moving into the central 
zones around noon and moving inland this afternoon. The GFS only 
shows very weak lift at best. High res models for the most part 
show coverage starting around noon in the coastal counties and 
then push it northward this afternoon. The disagreement is in the 
placement. Given the current upper level maps... upper level 
lift... and moisture it looks that most of the area will see a 
chance of rain today. The lowest chances towards Jackson County 
where there are slightly warmer 850 temperatures (more capping). 
Have also raised probability of precipitation for today given incoming high moisture 
values... weak upper level diffluence... and wedge of positive vorticity advection moving 
overhead. 


On Thursday models quickly begin to build ridging into the area 
from the East. Heights on Thursday afternoon rise to 594 dm. 
Forecast soundings at this time also develop a cap and bring lower 
precipitable water air into the area (1.40" - 1.60"). This will bring an end to 
the rain chances on Thursday. The ridge remains in close enough 
proximity to the area through Saturday to keep rain chances out of 
the forecast. By Sunday the ridge may drift far enough north to 
allow a return to afternoon showers and thunderstorms to the area. 
Definitely by the start of the next work week this looks possible. 
23 


Marine... 
a tight pressure gradient will produce moderate onshore winds 
through Thursday night. High pressure building into the area from 
the east will weaken the gradient and winds will diminish toward the 
end of the week. Light onshore winds will persist through the first 
half of next week. 43
