Previous discussion... /issued 220 am CDT Wednesday Jul 29 2015/
an upper level ridge will remain centered over the region today
but will begin to build to the west Thursday and Friday as a long
wave trough deepens across the East Coast. As the upper trough
axis moves to the east it will allow a weak cold front to move
south across the central and Southern Plains. The cold front
should reach North Texas Thursday but the slightly cooler and
drier air associated with it will not be noticeable until Friday.
The front should bring enough forcing for scattered showers and a
few thunderstorms. Precipitation chances will end from east to
west Friday night/Saturday as drier air moves in from the
northeast.

The upper level pattern will remain amplified through the middle
of next week with an upper ridge axis oriented roughly along The
Rockies and a long wave trough across the eastern Continental U.S..

Temperatures through the middle of next week will be above
seasonal normals overall with highs generally in the upper 90s to
around 100 and lows in the middle and upper 70s. The only
exception will be Friday and Saturday when temperatures will cool
closer to seasonal normals. It still appears that heat index
values in the northeast will reach 105 in a few spots this
afternoon. Therefore...we will leave the heat advisory in place
for Grayson...Fannin...Lamar and Delta counties. We will let the
day shift assess whether the advisory needs to be extended on
Thursday...but as of now it appears that the drier air associated
with the cold front Thursday should keep heat index values below
105.
