.DISCUSSION...

The upper ridge that has settled over Texas most of July will remain
in place the rest of the week and likely through the end of the
month. For the next couple of days though the ridge will flatten
enough to allow a few disturbances to move across the area.
Convection was fairly widespread yesterday over the western half of
the CWA. Storms developed along a sfc trough within a mid level
theta-e axis (340K+). Think this will be the case this afternoon and
again tomorrow as the theta-e axis shifts slightly east into parts
of the Permian Basin. Storms have already developed in the Davis
Mountains and are beginning to spread north and east. There are
also several boundaries around the area from overnight convection
that storms may form on. Even though temperatures are a few
degrees cooler than yesterday, most locations will still reach
near the 100 degree mark. These hot temperatures will create a dry
subcloud layer which will lead to gusty winds in and near any
thunderstorm. Locally heavy rain will also be possible due to slow
storm movement and PWATs near 1.5". A similar setup is expected
Wednesday before the ridge strengthens again over the area late
this week.

The theta-e ridge moves west back over the higher terrain Thursday
as will the precip chances. By the weekend, the ridge will be strong
enough to suppress most if not all convection. The only lingering
chance of an isolated storm or two will be over the Davis
Mountains. It doesn`t look like we will get a break from the heat
any time soon as models show the upper ridge across the area into
next week. Temperatures should reach near 100 each day unless you
are lucky enough to be in the mountains where highs will stay in
the low to mid 90`s.
