Severe Weather Alert Descriptions

 Heat Advisory  Statement as of 4:03 PM CDT on August 21, 2014


... Heat advisory now in effect until 7 PM CDT Friday...

* event... heat index readings of 104 to 108.

* Timing... by 10 am readings should exceed 101 and peak between
noon and 5 PM 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.

Aviation... 
VFR. Brief periods of MVFR decks over more rural (non-metro) hubs 
between 10-13z ... a very similar pattern to what has occurred 
over the past few mornings. Relatively lower moisture today will 
pick up a bit tomorrow but...with the region being under the 
influence of lower Mississippi River valley upper ridging...chances 
for any mentionable convection are too low to place within friday's 
taf package. A weakened onshore pressure gradient will make for 
slightly lower south-southeast breezes. 31 


&& 


Previous discussion... /issued 325 PM CDT Thursday Aug 21 2014/ 


Discussion... 
high pressure/slightly drier air making its presence known over southeast 
Texas this afternoon judging by the dew points/lack of radar coverage. 
This trend will likely continue through the rest of the week (and 
likely through the weekend) as the upper ridge settles over the 
northern Gulf Coast. Latest models appear to hold the ridge in 
place as we head into next week...with increased moisture/lift/pops 
not returning until next Tuesday/Wednesday or so. However given the uncertainty 
no real change with the extended part of the grids (which has 
isolated/low probability of precipitation back in starting early Monday morning over the coastal 
waters). 


The slightly lower dew points today have allowed for slightly lower 
heat indices this afternoon for the coastal counties. But readings are 
still within criteria for extending the heat advisory tomorrow. 41 


&& 


Marine... 
moderate southerly winds will persist through tonight and begin 
to relax by Friday morning. Surface high pressure will move from 
the central Gulf into the western Gulf by Sunday morning. The 
pressure gradient will slacken considerably allowing for light 
winds and low seas. These conditions should persist into next 
week. 39
