Aviation
Vfr across north texas through Saturday with scattered to broken
mid and upper level clouds.

A weak cold front currently across oklahoma will move slowly south
today. A few showers or possibly a thunderstorm will accompany
the front mainly across the red river. Low precipitation chances
will spread south with the front tonight but coverage will be too
limited to include in this forecast.

A south to southwest wind across the metroplex TAF sites this
morning will veer through the day and eventually become northeast
this evening with the passage of the front. Wind speeds will
remain generally less than 12 knots. The wind in waco will
remain southerly through 12z Saturday.

present on the surface charts this morning is a cold front, which
appears to have made its way south of frederick, oklahoma, and
just south of the i-40 corridor. With little in the way of
convection to its north and limited cold advection pressure rises
noted, this front will only inch southward this morning before
slowing even further this afternoon as diurnal mixing ensues.

Modest isentropic ascent is present along and behind the front at
the nose of a 30 kt low-level jet, so a renegade shower or two
appears possible this morning near the red river. However, with
moisture along the 310 k surface in short supply, wouldn't
anticipate much more than this.

The main story today will once again be the oppressive heat on
what may very well be the hottest day of the year so far for many
of us. There are still some questions regarding the degree of mid-
and high-level cloud cover that gets thrown our way, but latest
indications point to just some passing high cloud cover and
percolating high-based cumulus with the heating of the day. As
lower-level winds veer out of the west ahead of the front, drier
and warmer air will advect into the region, and guidance continues
to indicate h85 temps warming to around +25 c in the prefrontal
thermal ridge. The implication here is that temperatures will
rocket towards the century mark and just above this afternoon.

Local research supports highs in the metroplex as warm as 104-106
degrees given the h85 temperatures and westerly southwesterly
winds. We've undercut these numbers just a hair with the
expectation of slightly filtered sunshine, but are advertising 103
readings across the metroplex and at waco. The one consolation
here is that vigorous mixing should allow dewpoints to fall into
the mid and upper 60s, resulting in heat index values in the 105
to 110 degree range as opposed to 115+. A heat advisory remains in
effect east of a killeen to mineral wells line, and south of
denton to sulphur springs. It's possible the sites immediately
along the red river briefly flirt with the 105 threshold, but
slightly increased cloud cover there precludes a northward
extension of the current advisory.

During the afternoon and evening hours, the front will finally
start sinking south of the red river. With such vigorous mixing
today, it appears that any instability of significance will
actually be displaced behind the front where dewpoints will be
higher. As a result, we've confined low (20%) pops to our
immediate red river counties this afternoon. Dewpoint depressions
of 30 degrees (+) will support a downburst wind threat if any
isolated convection is able to develop.

Tonight, weak upglide along the front may support the development
of a broken band of showers and thunderstorms across our
northeastern counties, but the combination of limited deep
moisture and subsidence overhead will keep pops capped at 30%.

Popcorn convection then appears possible pretty much area-wide
during the afternoon on Saturday. With high temperatures in the
99-102 degree range forecast across central texas, heat index
values of 105-108 degrees are possible, mainly near the region
bounded by the i-35 and i-20 corridors. Given uncertainties
regarding cloud cover on Saturday, however, we have not extended
the heat advisory at this juncture. If storm cloud coverage
continues to look limited, a one-day extension of the heat
advisory would be warranted.

By Sunday and Monday, drier and more stable air will have worked
its way through the eastern half of the forecast area, relegating
any low shower storm chances to west of i-35. Monday actually
looks--dare we say it--rather comfortable for the last day of july
with highs in the lower to middle 90s and low 60s dewpoints.

During the middle and end of next week, moisture will gradually
return to the region with north northwesterly flow aloft
continuing as the subtropical high consolidates across the
intermountain west. With a mean trough looking to set up across
our area, several decent shots at showers and storms appear
possible through this period. This will provide the added benefit
of keeping temperatures in check through the end of the week.
