Severe Weather Alert Descriptions

 Heat Advisory  Statement as of 2:15 PM CDT on July 31, 2015


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

The National Weather Service in Houston/Galveston has issued a
heat advisory... which is in effect until 7 PM CDT this evening.

* Event... peak heat index values around 109 to 111 degrees.

* Timing... this afternoon into early evening.

* Impact... overexertion in this heat will likely lead to
dehydration... and could result in heat exhaustion or heat
stroke.

Precautionary/preparedness actions...

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

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 
1050 am CDT Friday Jul 31 2015 


Update... 
one note...after checking through the temperatures decided to up 
the highs for today a bit to be more in line with the mav 
guidance. Drier air filtering in from the northeast will likely 
aid in a bit higher numbers. 


40 


&& 


Previous discussion... /issued 1036 am CDT Friday Jul 31 2015/ 


Discussion... 
a cold front was entering into the northeastern counties of the 
forecast area at middle morning...with a prefrontal trough across 
Galveston Bay through metropolitan Houston and into the cll area. Another 
trough was out in the open waters of the Gulf. Isolated showers 
have endeavored to develop over the inland areas south of the 
prefrontal trough while scattered larger showers were over the 
open waters of the Gulf east of that surface trough. 


The high res short range models looked fairly similar for the 
outlook today. Liked the hrrr which has isolated convection along 
and southwest of a line from about cll to Houston to Galveston 
late this morning through the early afternoon. As the front 
continues moving southwestward...the rain chances will push more 
over the southwestern counties during the late afternoon and early 
evening. 


The other issue of note will be the heat index. Values are still 
forecast to reach advisory criteria over the coast during the late 
afternoon period. The drier air behind the front will likely have 
an impact over Chambers and maybe Galveston County. Since the 
timing is uncertain at this time...will keep the heat advisory up 
for the immediate coastal counties but will drop counties later 
today if needed. 


Tweaked the probability of precipitation and weather a bit to account for the latest radar 
and model trends. 


40 


Previous discussion... /issued 414 am CDT Friday Jul 31 2015/ 


Discussion... 
overnight convection over the Brazos Valley continues to diminish 
as it exits the forecast area...with very warm temperatures 
persisting across southeast Texas early this morning. Surface 
analysis at 05z showed a plume of 75+ degree dew points draped 
along the Texas coast and extending into northeast Louisiana. 
This... combined with leftover clouds from last night/S storms... 
was contributing to heat indices in the low to middle 90s as of 3 am 
CDT at a few sites. A weak frontal boundary was also analyzed on 
this map stretching North Texas and on into northern Louisiana. 
This front will play a major role in how the weather evolves today 
for the region... both in terms of thunderstorm chances as well as 
concerns about heat. 


The 00z Lake Charles sounding reported a precipitable water value 
of 2.26 inches... with overnight GPS-met measurements across the 
region showing a similarly moist airmass /2.1 to 2.3 inches around 
the Houston metropolitan and along the coast/. High resolution guidance 
is fairly consistent with developing scattered showers and 
thunderstorms along the front as it slowly drops southwestward 
today... but agreement is poor in the actual timing of this 
feature and consequently the location of the greatest areal 
coverage. 


The GFS appears to be by far the most aggressive and sweeps 
moisture away from the Interstate 45 corridor and points east by 
18z. Comparison of surface Theta-E fields however /which represent 
moisture and instability present/ reveal stabilization for the 
eastern half of the region closer to 00z... with relatively good 
agreement between both higher resolution and synoptic models on 
this solution. Based on this... highlighting highest rain chances 
west of the Interstate 45 corridor today along and ahead of the 
anticipated frontal position. Additionally... a dry sub-cloud 
layer and dcape values 1100-1300 j/kg this afternoon raises 
concerns for at least an isolated gusty wind threat from stronger 
thunderstorm activity. 


A later frontal passage also means that stifling conditions will 
persist ahead of the front today and have gone ahead and issued a 
heat advisory for the coastal counties of Matagorda... Brazoria... 
Galveston... and Chambers. Heat indices in these areas reached 109 
to 111 degrees yesterday. With the anticipated slow progression 
of the front today combined with naefs anomalies highlighting 
anomalous temperatures again along the coast /a return interval 
of approximately once every 10 years/... wanted to highlight the 
increased potential for health impacts. If the front moves through 
faster than anticipated however... drier air filtering in behind 
the front will actually help lower heat index values and advisory 
criteria may not be met. 


For the remainder of the short term... the front is expected to 
push off the coast tonight. Drier air filtering in behind the 
front will help limit rain chances over all but the coastal waters 
on Saturday. This slightly drier air may also allow for some 
overnight lows in the upper 60s in the Piney Woods region... with 
low 70s to near 80 possible elsewhere. High temperatures are not 
expected to differ much from today on Saturday but a drier airmass 
in place will help mitigate against higher heat index values. 


The region will remain on the eastern periphery of the upper ridge 
on Sunday and through the rest of the forecast period... with the 
center of this feature shifting a bit around the Southern Plains 
during this time. Low thunderstorm chances will continue in the 
vicinity of the stalled frontal boundary with dry conditions and 
above normal temperatures inland persisting into the middle of 
next week. 


Huffman 


Marine... 


Storms have departed the waters but more could coming late this 
morning through evening. Winds will generally be variable northerly 
to easterly across the Upper Texas coastal waters with an afternoon 
seabreeze forming. Eventually a diffuse cold front sags out into the 
Gulf waters late tonight and winds increase slightly. 850mb front 
appears to stall well offshore and should become a focus for 
redevelopment of showers and thunderstorms but probably just southeast of the 
Upper Texas coastal waters. Will need to keep an eye on the remains 
of the boundary Saturday afternoon-Sunday as the Gulf is plenty warm 
enough and shear relaxes. Moisture surges back into the area late 
Sunday and south to southeasterly flow returns and continues through 
Friday.

Aviation... 


VFR for now but may get a few spots with mifg around sunrise mainly 
the more rural sites cxo northward. Challenging forecast for today. 
Dry air should intrude into the region from the northeast but a few 
of the models appear too quick to dry things out. L/v winds will be 
the north until the diffuse frontal passage. Am thinking that cll-hou-sgr-lbx 
may see some thunder close by this afternoon and will likely add 
this in the 12z package if not sooner. Iah may be on the northern 
fringe of where pooled moisture and sagging boundary interact so for 
now will probably leave thunderstorms in the vicinity out but it will be close. Deep mixing 
again today with light winds in the profile so storms should be slow 
moving. Drying northeasterly to easterly flow should overspread 
iah/hou by late afternoon/early evening leading to clear skies.
