.PREV DISCUSSION... /issued 210 PM CDT Tue Jul 4 2017/

DISCUSSION...

Upper ridging is over the southwest part of the country with an
upper low over northeast Oklahoma/southwest Missouri. This pattern
has resulted in northwest flow aloft over the CWA. There is a chance
of storms again across the area this afternoon into tonight due to
good CAPE and lapse rates across the area. Enhanced omega and
remaining outflow boundaries across the area will also aid in
developing convection. Expect storms to develop across the higher
terrain this afternoon and then develop into the Permian Basin later
in the afternoon. The hi resolution models indicate an increase in
convection across the Permian Basin late this afternoon with an MCS
possibly coming into the area late this evening into tonight. Due to
these conditions, have increased pops across the area this afternoon
into tonight. Temperatures today are expected to be similar to
yesterday with highs mostly in the upper 90s to triple digits.

Chances of thunderstorms continue into Wednesday with a good supply
of moisture but models are less clear on where convection will
develop. Development of convection tomorrow may depend on where it
is today. Temperatures are expected to be a little cooler on
Wednesday due to cooler 850 mb temperatures. The upper ridge
continues to build over the western and central part of the country
on Thursday and the upper flow becomes northeasterly over the CWA.
Temperatures will mostly be in the mid 90s across the Permian Basin
on Thursday. There remains a chance of storms across the Davis
Mountains and possibly extending to the Lower Trans Pecos and Big
Bend area on Thursday. Not too much change for Friday except
slightly warmer temperatures. The upper pattern remains the same
over the weekend with mostly dry conditions. The upper ridge becomes
more centered over the central conus during the early to mid part of
next week. This will not have much impact on local conditions with
temperatures mostly in the mid to upper 90s and rain mostly
remaining confined to west of the Upper Trans Pecos.
