.DISCUSSION...
The main weather stories for North and Central Texas will be the
heat today and then thunderstorm chances late this afternoon
through the weekend along with some cooler weather.

Tropical Depression Cindy continues to move northeast across
Central Arkansas this morning. In its wake, we will be in an area
of subsidence today. With skies being or becoming mostly sunny,
temperatures will rise into the 90s to 103 degrees across the
region. These temperatures, when combined with dewpoints in the
mid 60s to mid 70s, will result in afternoon heat index values of
100 to 110 degrees across the forecast area. A Heat Advisory is in
effect from Noon through 7 PM today for areas from Bowie to
Lampasas east to Bonham and Hearne where heat index values of 105
to 110 degrees are expected. Winds in the 5 to 10 mph range will
provide little relief from the heat.

A cold front that extended from northeastern Kansas southwest
into the Texas Panhandle at 3 AM will move into the northwestern
part of the forecast area late this afternoon and through all but
the southeastern zones by sunrise Saturday. Expect scattered
thunderstorms to develop along this front and this activity will
become more numerous tonight as the front moves southeast. Hail to
1 inch in diameter, and wind gusts to 60 mph will be possible
with the strongest storms late this afternoon and this evening.
Locally heavy rain will also be a weather hazard as well as cloud
to ground lightning.

The summer cold front will sweep through the rest of the forecast
area Saturday night. The best chances of rain will shift to the
south of the I-20 corridor by midday. With northwest flow aloft
continuing and a weak frontal boundary to our south, scattered
showers and thunderstorms will remain in the forecast through
Monday. Low chances of showers and thunderstorm will return
Wednesday and Thursday mainly southeast of a Temple to Sulphur
Springs line.

Temperatures will be below seasonal normals Saturday through
Tuesday. Some spots across the north may see temperatures top out
in the mid to upper 70s on Saturday; otherwise, expect highs
mostly in the 80s through Tuesday. Temperatures will warm up mid
week with some mid to upper 90s possible by the end of the work
week.

.AVIATION... /Issued 1130 PM CDT Thu Jun 22 2017/
Main concern in the next 24-30 hours will be convective potential
at TAF sites Friday evening through Saturday morning.

Winds have returned to the SSE this evening and will remain SE
through the TAF period. Abundant low-level moisture should cause
MVFR stratus to develop mostly across East TX in the next 6-8
hours, and have decided to tempo these conditions at Waco which
could be skirted by this stratus Friday morning; these cigs
should be 1-2 kft AGL. It`s unlikely that DFW Metroplex airports
will be affected by this batch of stratus.

A cold front will enter North TX Friday evening leading to the
development of showers and storms throughout the evening and
overnight hours. Have included two periods of VCTS in the DFW TAF
as it appears there will be initial scattered activity
along/ahead of the front followed by more widespread rain and
thunderstorms behind the front overnight. Some prevailing TSRA
will probably be necessary in subsequent TAF issuances, but
confidence in timing is too low to define these windows in the
TAFs right now. Waco could see scattered storms beginning a few
hours later. Activity should be on a downward trend by mid
morning Saturday, but post-frontal MVFR cigs may hold through
much of the day. Winds will be out of the NE at 10-15 kts behind
the front.
