DISCUSSION...
The primary forecast focus is on the persistent heat, continuing
into the weekend.

Currently, it`s still hot out there, which most of you probably
noticed. It`s 100 degrees up in Buffalo, and several sites across
the Panhandle are at or a few degrees above the century mark.
Elsewhere, mid to upper 90s are the story and will continue to be,
daily, through the remainder of the week.

Synoptically, an expansive 500mb ridge will hold over the central
United States through Friday. Overall, conditions will be consistent
for the next few days, with highs both Wednesday and Thursday in the
mid 90s to the low 100s. Friday is still looking like the hottest
day of the week, for most. A surface trough moving eastward off the
Rockies Thursday into Friday will result in increased
south/southwest winds off the Llano Estacado and across Oklahoma.
850mb temperatures will near 30 C along the Texas Panhandle/OK
border, with upper 20s C temperatures to central Oklahoma. Decided
to run with a persistance forecast, with highs on Friday in the
upper 90s/low 100s. Highs in southwestern Oklahoma could easily
reach 102 to 104 F. The good news, dew points across western
Oklahoma into north Texas will be lower than the the past few weeks,
50s F for most, in the afternoon. For central Oklahoma, afternoon
dew points will remain in the 60s to 70 F, with fairly humid
conditions, with heat indices flirting with advisory criteria.
Therefore, will continue to hold off on any advisory criteria at
this time.

From yesterday`s AFD: More importantly, with daily highs in the
upper 90s/low 100s, the risk of heat related illnesses will
gradually compound, as low`s each night will only dip into the mid
to upper 70s. This lack of recovery/cooling may impact those most
vulnerable to heat related illnesses, the elderly and infirmed. Be a
good neighbor, check on the elderly in your neighborhoods, make sure
they have access to air conditioning or, at least, a good working
fan. Additionally, 21 children have died this year as a result of
being left in a hot car. Please, please, check the backseat when you
park. Do not leave children or pets in parked cars.

Over the weekend, hot temperatures will continue on Saturday, with
highs reaching 100 in a few places. However, a weak 500mb short wave
crossing the plains Will bring a weak frontal boundary and a return
of rain chances Sunday into Monday.
