Severe Weather Alert Descriptions

 Heat Advisory  Statement as of 4:06 am CDT on August 23, 2014


... Heat advisory remains in effect until 7 PM CDT this evening...

* event... heat index readings of 101 to 107.

* Timing... heat index values will exceed 100 degrees by 11 am.
Heat index values will exceed 105 degrees between noon and 4 PM
and then fall slowly during the early evening.

* Impact... overheating and dehydration can quickly occur if you
will be outdoors today. It can be difficult to recognize the
signs of heat exhaustion on yourself... so plan to take
frequent breaks. You may recognize the signs of heat
exhaustion more readily in others.

Precautionary/preparedness actions...

Know the signs and symptoms of heat exhaustion... heavy sweating...
fatigue... confusion... headache... pale and clammy skin... thirst...
dizziness... nausea and vomiting... rapid heartbeat... cramps or
weakness.

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activities to early morning or
evening. Wear light weight and loose fitting clothing when
possible and drink plenty of water. Be sure to drink plenty of
water hours before strenuous activity and then during.

To reduce risk during outdoor work... the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.

Each year... a number of fatalities occur nationwide due to
children accidentally being left in vehicles during the Summer
months. In the past dozen years... 500 children have died due to
hyperthermia after being left in or gaining access to cars. Never
leave children or pets unattended in a vehicle not even for a
minute. Remember... beat the heat... check the backseat.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1223 PM CDT Sat Aug 23 2014 


Discussion... 
see aviation for 18z taf issuance. 


&& 


Aviation... 
VFR conditions expected through the current taf period. Cumulus 
along the coast beginning to show some more vertical development 
with a small shower now showing up roughly 10nm NE of lbx. Could 
see a few more showers through the afternoon but coverage will not 
be extensive enough to mention in the tafs. Expect late seabreeze 
arrival at iah this afternoon with winds briefly becoming east-southeast. 
Expect light/variable winds overnight as surface high sets up 
just offshore. 38

Previous discussion... /issued 1022 am CDT Sat Aug 23 2014/ 


Discussion... 
cloud cover a little more sparse than yesterday but a degree 
cooler at most sites. Dewpoints are down but GPS-ipw is up 
slightly so a mixed set of messages. As previous forecaster pointed 
out the 850 temperatures/heights are down a little and so am inclined to 
lower temperatures slightly but have stuck with the forecast 
values except to drop the 100s in the far west. 105-106 should be 
the highest heat index readings today and may be able to parse off 
a County or two from the heat advisory in the afternoon package.

Previous discussion... /issued 631 am CDT Sat Aug 23 2014/ 


Discussion... 
see the 12z aviation discussion below.

Aviation... 
patchy ground fog and possibly some stratus may impact some of the 
more rural sites between 12z and 15z. Otherwise...VFR is expected 
through this evening with a possible return of patchy ground fog 
at the more rural sites after 09z tonight. There is an outside 
chance for isolated showers to form along a seabreeze mainly 
during the afternoon period today. The latest high resolution 
models are suggesting a time frame of about 17z to near 00z mainly 
from the coast into the metropolitan Houston sites.

Previous discussion... /issued 402 am CDT Sat Aug 23 2014/ 


Discussion... 
at 08z...weak high pressure was located over the west central Gulf 
and a weak trough of low pressure remained over the western High 
Plains. At 850 mb...high pressure was noted over eastern Louisiana 
and low pressure was located over the intermountain west with a 
trough extending south along the Arizona/nm state line. 850 mb moisture 
was confined to coastal Louisiana and 850 temperatures had cooled 2 c at 
lch. At 700 mb...high pressure was located over Louisiana with 
very dry conditions noted at this level. At 250 mb...a strong 
upper level ridge extended from eastern Missouri to eastern 
Georgia. A weak upper level low was noted over north central 
Mexico and another weak low was located over the Texas Panhandle. 
Upper flow over East Texas looks confluent at 00z. 


Models have been forecasting cooler 850 temperatures for today and the 
00z cooling at lch may portend this development. Ensemble guidance 
still supports very warm temperatures today as does the European model (ecmwf) 
guidance. Will continue to forecast maximum temperatures in the upper 90s 
inland...lower 90s coast. Middle levels remain dry and some of this 
dry air will again mix to the surface so heat index values will 
again remain close to the actual air temperature over the western 
zones. The heat advisory for the coastal counties is a bit tenuous 
as dew points are a bit lower than previous days. Not sure the 105 degree 
threshold will be reached today but will maintain the heat 
advisory. Prefer not to extend at the advisory into Sunday at this 
time and wait and see how much dry air mixes to the surface this afternoon. 
Can't rule out an isolated rain showers this afternoon but probabilities 
are very small. 


High pressure will remain in control through Monday with very warm 
temperatures and dry conditions. Conditions will change quickly 
Monday night as an inverted upper trough over the Gulf pushes west 
toward the Upper Texas coast. This feature will bring a surge of 
fairly deep tropical moisture into southeast Texas late Monday night with the 
moisture hanging around through Friday. The NAM is particularly 
aggressive with precipitable water values approaching 2.40 inches by 12z Tuesday. 
An upper level trough moving slowly across the Central Plains 
during the middle-week period will keep unsettled weather in the forecast 
with mainly diurnal rain showers/thunderstorms and rain expected Tuesday through Friday. Will 
carry chance probability of precipitation through Friday with convective temperatures around 90 
and precipitable water values at or above 2.00 inches. Global models diverge significantly 
Friday and beyond. The GFS brings a front through the area with 
surface dew points falling into the 50s and precipitable water values dropping to less 
than an inch. The GFS is considerably faster with the upper trough 
moving across the Central Plains. The European model (ecmwf) is much slower with 
the trough and never brings the front through the County Warning Area. The 
Canadian is also slower with the trough so have leaned toward the 
slower solutions. The European model (ecmwf) keeps the upper trough/weakness across 
the Southern Plains through Sunday so will keep rain chances in the 
forecast through next weekend. 43
