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

* 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.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
710 PM CDT Wednesday Aug 20 2014 


Discussion... 
00z aviation discussion below. 


&& 


Aviation... 
primarily VFR. Areawide northern-based convection has significantly 
weakened and moved out of the area. A quiet taf package in relation 
to previous days as eastern ridging is forecast to expand westward 
and suppress convective activity tomorrow. The higher probability 
lies in isolated showers...with maybe a lone thunderstorm or two... 
but am anticipating much less areal coverage Thursday. Higher 
precipitable water air mass of greater than two inches residing over the 
northwestern Gulf is prognosticated to move onshore during the overnight 
hours and increase the chance of mainly scattered maritime showers 
(vcsh in kgls). Brief periods of MVFR ceilings during the 11 through 
13z hour...but some hubs will fall to MVFR for less than an hour 
so have placed some tempo's in to cover this chance occurrence. 31 


&& 


Previous discussion... /issued 353 PM CDT Wednesday Aug 20 2014/ 


Discussion... 
the deeper tropical moisture appears to have arrived across southeast Texas 
this afternoon (per the ongoing convection inland and over the coastal 
waters). Did extend chance probability of precipitation through this evening given the curr- 
ent trends. Otherwise not a lot of change with the grids the next 
few days as models continue with forecast of the building upper ridge 
from the east. Probability of precipitation should be going down but lingering +2"pw air- 
mass could produce isolated activity tomorrow morning/aftn. However as 
ridging settles over the region this weekend...the drying airmass 
will be less supportive of anything more than very isolated storms on/ 
near the seabreeze. 


But that being said...GFS is hinting at the return of deeper Gulf 
moisture (+2"pws) Sun night/early Monday. Not too surprised with the 
slight change as the upper ridge shifts a bit more north/NE next week 
and we get more on the underside of it (i.E. A more open gulf)... 
thus heralding the return of scattered mainly daytime heating generated 
precipitation. This should also help lower temperatures down (a couple of degrees 
or so) next week. In the meantime...will extend the heat advisory 
for the coastal counties through tomorrow evening. 41 


Marine... 
the surface pressure gradient will produce moderate to strong onshore 
winds tonight into Thursday. Scec may be needed tonight into Thursday 
morning. 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. 39
