Severe Weather Alert Descriptions

 Heat Advisory  Statement as of 3:51 PM CDT on August 19, 2014


... Heat advisory remains in effect until 7 PM CDT Wednesday...

* event... heat index readings of 105 to 110.

* Timing... by 10 am readings should exceed 103 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... 
no major changes to this early morning package. Scattered offshore 
precipitation in Matagorda bay's area signals that kgls may tempo 
down to MVFR (ceilings) with vicinity showers through sunrise. 
Moderate chance for recurring daytime convection with less areal 
coverage. Latest guidance still forecasts the eastern upper ridge to 
expand over region and suppress precipitation going into the 
weekend. 31

Previous discussion... /issued 844 PM CDT Tuesday Aug 19 2014/ 


Discussion... 
showers and thunderstorms coming to an end this evening with the loss 
of heating. Current forecast and reasoning for the rest of the week 
covered in discussions below looks good. Plan on no major changes 
to the grids until after the arrival of all 20/00z models.

Previous discussion... /issued 653 PM CDT Tuesday Aug 19 2014/ 


Discussion... 
00z aviation discussion below. 


Aviation... 
this afternoon's convection pulling off to the northeast with a 
quiet overnight period. Upper level trough across central Texas 
is forecast to dissolve into the western expansion of the currently 
northern Gulf-centered upper ridge. Confidence is not particularly 
high that there will not be a continued middle-upper layer weakness... 
or shear zone aloft...that will still provide the lift of an eastern 
Texas highly moist and unstable air mass. Although better behaving 
modeling has return late morning into early afternoon widely scattered 
convection firing up once again...there is less areal coverage in 
relation to previous days. Thus...placed thunderstorms in the vicinity and probability 30s in during 
warmth of day to not totally bite on return thunder...or advertise 
the modest probability that eastern ridging will not completely 
absorb western troughing (for one last day). 31 


Previous discussion... /issued 344 PM CDT Tuesday Aug 19 2014/ 


Discussion... 
decent coverage of precipitation today across the area. Like yesterday...expect 
it to dissipate early this evening west/ loss of heating. Will need to 
keep an eye on outflows from la storms moving south-southwest as they could 
serve as a focus for additional development near Chambers Colorado & 
possibly nearby nearshore/Gulf waters. Deeper surge of western 
Gulf moisture seen on Sat pictures arrives Wednesday morning and should 
provide one more day of scattered precipitation coverage on Wednesday. Hopefully 
cloudiness & temperatures will linger later at the coast and limit heat 
indices below 105. Until that occurs heat advsy continues along 
the coast (peaked 105-108 today). 


Ridge amplifies/expands and becomes centered over la/MS/AR in the 
coming days. Combination of increased subsidence and lower 
moisture levels will limit chances of precipitation across southeast Texas Thursday 
through the weekend. Temperatures might climb a degree or two as well but no 
sig thickness changes seen. Getting to be that time of year to 
keep an eye on the tropics. A few models are suggesting some 
eventual development in the Atlantic. Until if & when something 
becomes better organized out there...expect wildly varying & 
frequently changing solutions via models. 47
