Severe Weather Alert Descriptions

 Heat Advisory  Statement as of 2:34 PM CDT on July 23, 2014


... Heat advisory in effect from noon Thursday to 10 PM CDT
Friday...

The National Weather Service in Fort Worth has issued a heat
advisory... which is in effect from noon Thursday to 10 PM CDT
Friday.

* Location... all areas along and east of a line from Graham to
Killeen... including the Sherman... Dallas Fort
Worth... Waco... Temple and Killeen areas.

* Temperature... high temperatures from around 100 to 105 degrees
with heat index readings reaching the 105 to 108 degree range.

* Impacts... those exposed to the extreme heat over a prolonged
period may develop heat related illnesses.

Precautionary/preparedness actions...

A heat advisory means that afternoon heat index values are
expected to meet or exceed 105 degrees for at least two
consecutive days.

Be sure to check on persons with health problems and the
elderly... as they are the most susceptible to heat exhaustion and
heat stroke. Never leave Young children or pets in an enclosed
vehicle... even for a short time... as temperatures can quickly
rise to life threatening levels.

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.





 Air Quality Alert  Statement as of 1:36 PM CDT on July 23, 2014


... Ozone action day...

The Texas commission on environmental quality (tceq) has issued
an ozone action day for the Dallas-Fort Worth area for Thursday,
July 24, 2014.

Atmospheric conditions are expected to be favorable for producing
high levels of ozone air pollution in the Dallas-Fort Worth area
on Thursday. You can help prevent ozone pollution by sharing a
ride, walking, riding a bicycle, taking your lunch to work,
avoiding drive-through lanes, conserving energy, and keeping your
vehicle properly tuned.

NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
755 PM CDT Wednesday Jul 23 2014 


Aviation... 
outflow boundary moving through eastern Dallas County and will 
move through kdal...kdfw...kgky through 02z. 88d kfws showing some 
speeds to 40 knots out of the northeast-east...but would expect 
25-35 knots as they move across the terminals. 75 


&& 




Previous discussion... /issued 243 PM CDT Wednesday Jul 23 2014/ 
thunderstorms have begun to develop northeast of the region in 
proximity of a weak cold front and Stout shortwave. Model trends 
indicate that convection will be on the increase to our 
northeast...with the northeast flow regime driving this activity 
southwestward toward North Texas. At the current rate of 
development and movement...convection should begin to cross over 
into Lamar County near Paris and surrounding areas around 6 PM or 
so. The time of day would suggest that some of these storms will 
be strong to possible severe...with damaging winds being the main 
threat as they affect the northeastern counties. A weakening 
trend is expected as cells move farther southwest...due to the 
waning of surface heating and also to the increasing subsidence 
from the dominant ridge to the west. Still...low probability of precipitation will be 
maintained in the metroplex and surrounding areas through midnight 
or so....with activity dissipating thereafter. 


A low chance of thunderstorms will arise again Thursday as a weak 
front sags south to near the I-20 corridor...providing focus for 
isolated development...mainly in the afternoon. West of I-35...it 
appears that subsidence from the upper ridge will shut off any 
attempt for convective development. 


The primary weather concern over the next few days will be the 
increasing temperatures and uncomfortable heat. After carefully 
running and finalizing the temperature/dewpoint forecast...the 
resulting apparent temperature grids are indicating heat indices 
fairly widespread in the 105 to 108 degree range both Thursday afternoon 
and Friday afternoon. The only exception to this is the 
southwestern counties where drier conditions should keep the heat 
index below 105. We will go ahead and include a heat advisory for 
most of North Texas...excluding the areas west of a Mineral Wells 
to Gatesville line where conditions should remain below criteria. 
The advisory will be in effect from noon Thursday until 9 PM 
Friday night. Please use caution when participating in outdoor 
activities...stay hydrated...and schedule strenuous activities for 
early in the day when possible. 


The weather pattern will begin to shift on Monday...as an upper 
trough deepens over the eastern states and the upper ridge slides 
to the west. This will place North Texas in a strong north to 
northwest flow regime. This pattern will send another rare July 
cold front south from the plains across the Red River on Monday. A 
chance of rain can be expected Monday and Tuesday associated with 
the front....with cooler conditions expected for most of next week 
behind the front.
