.DISCUSSION...
An upper high over the Panhandles will remain through the weekend.
A frontal boundary across the extreme southern Texas Panhandle or
the far northern portions of the Texas South Plains region will
allow for a weak upslope surface flow as abundant low level
moisture prevails across the forecast area. Forecast model
soundings indicate precipitable water values of 1.38 inches to
1.78 inches today through Tuesday which is at the 90th percentile
or higher for the Panhandles for the end of July and the first few
days of August. The mid level flow is expected to be weak, mainly
from the west and southwest 5 to 10 knots, today through the
weekend indicating slow moving convection. The slow moving
stronger storms will be capable of producing locally very heavy
rainfall and possible flooding/flash flooding concerns. Held off
issuing a Watch for now as confidence low as far as timing and
coverage of convection is concerned. Therefore, placement of a
Watch uncertain at the moment although a Watch could be needed
later.

The upper high shifts further south and west by early and middle
of next week allowing for northwest flow aloft to bring shortwave
energy to track south and east out of the Rockies and across the
Panhandles. Convection should increase during the first half of
next week across the forecast area. The possibility for some
storms to become strong to marginally severe exists as better
shear forecast early next week. Drier conditions possible during
the latter half of next week.
