VFR conditions will prevail at most sites through the period, as
mid and high level cloudiness stream across the area. There is a
little MVFR cigs other the higher clouds that may affect the
southern terminals, but it would very brief if it does. Otherwise,
south winds of 5 to 15 knots will continue.

Short term...
(today and tonight)

Fairly quiet July 4th across west central Texas. We are a little
more concerned about the possibility of a few showers and
thunderstorms across the Big Country along and north of I-20 this
afternoon. Latest hrrr and ttu WRF both show isolated activity
developing as far south as Abilene and Sweetwater and even
Brownwood, but have held off on bringing the pop chances this far
south quite yet. If course, these models also show convection
ongoing now where there is not anything ongoing, so initialization
is poor this morning. Will bring a mention back into the northern
Big Country however, roughly north of a Hamlin to Albany line. Will
need to watch the area farther south however as the day GOES by.

Otherwise, lots of mid and high cloudiness will continue to stream
across the area. This will keep temperatures pretty close to where
they were yesterday.

Long term...
(sunday and Sunday night)

The conditions aloft and in the low levels will be unfavorable for
convective development. Highs will be in the upper 80s to mid 90s with
lows in the upper 60s to mid 70s.

(Monday through wednesday)

There will be a chance of rain across much of west central Texas for
the early to middle part of the week. The combination of disturbances in
the upper level west-northwest flow, a surface boundary and some
instability will bring a few rounds of thunderstorms to the area.
The ecwmf model is the heaviest with the quantitative precipitation forecast amounts and the GFS and
CMC is drier. Going with chance pops across much of the area, with
likely pops across the northern Big Country during the Tuesday
daytime hours. However, have kept Kimble, Mason and San Saba
counties dry due to being closer to the high pressure ridge axis
aloft.

(Wednesday night through saturday)

A return to a dry forecast as an upper level high pressure ridge
builds across the Southern Plains. Highs will be in the 90s with
lows 70 to 75.
