DISCUSSION
A COLD FRONT APPROACHING FROM THE WEST WILL BRING GUSTY WINDS TO THE
AREA OF THE SPOT LATER THIS MORNING AND THROUGH THE EVENING. NO RAINFALL IS
EXPECTED FROM THIS COLD FRONT AT THE LOCATION OF THE SPOT TODAY. WINDS
WILL PREDOMINANTLY BE OUT OF THE SOUTHWEST TODAY, AND LOOK TO INCREASE
TO AROUND 9-15 MPH WITH GUSTS UP TO 15-20 MPH THIS AFTERNOON. THIS WILL
LEAD TO DECENTLY HIGH DISPERSIONS THROUGH THE AFTERNOON HOURS, ESPECIALLY
WITH MIXING HEIGHTS CLIMBING TO AROUND 4000FT. THESE WINDS COMBINED WITH
LOW RH VALUES DROPPING TO THE MID 30S BY THE AFTERNOON HOURS WILL ALSO
LEAD TO INCREASED FIRE CONCERNS DOWNSTREAM OF ANY FIRE TODAY. THIS MEANS
THAT SOME CAUTION SHOULD BE TAKEN WHEN BURNING TODAY GIVEN THE WINDS AND
LOW RH VALUES ACROSS THE SPOT LOCATION.
