.DISCUSSION...
The strong winds on Tuesday and Wednesday will elevate fire
weather concerns over the region, especially NE OK. Dewpoints
should come up enough on Tuesday to keep RH values from dropping
into fire weather headline criteria. The gusty northwest winds
behind the front Wednesday may actually pose a bigger fire weather
risk across portions of NE OK as RH values get fairly low.
