National Weather Service Midland/Odessa TX
310 AM CDT Mon Aug 20 2018

.DISCUSSION...

A mid level impulse along with a southward moving cold front will
bring a chance of storms to much of the Permian Basin this
morning. Storms are beginning to develop south of Lubbuck and will
slowly move south through the morning hours. Moderate to locally
heavy rain could cause minor flooding especially in urban areas.
These storms along with the cold front will move south across the
area with "cooler", drier air filtering in by this afternoon. High
temperatures should be much closer to normal today.

The heat quickly returns Tuesday through the rest of the week as
upper ridging builds back in from the west. Subsidence will keep
skies dry while increasing heights and mid level temperatures will
allow afternoon highs to climb back above normal. The hottest days
look to be Thursday and Friday when many locations outside of the
mountains could see temperatures near or above 100. An early look at
the weekend ahead currently looks hot and dry as well.
