lowered temperatures a few degrees at some of the locations around

fire weather will become a concern again Wednesday as temperatures
warm back to unseasonably warm levels, and afternoon relative

stay below red flag criteria, so will not issue a Fire Weather
Watch at this time, but conditions will need to be monitored. A
cold front will move across the area Wednesday afternoon and
evening, resulting in cooler temperatures for Thursday and Friday.
An upper level storm system is forecast to lift northeast out of
northern Mexico across the Southern Plains over the weekend. The
models have not shown good run to run consistency with this
