.DISCUSSION...
Gusty southwest 20 foot winds of 10 to 15 MPH at ignition, with
gusts to 20 MPH, will quickly increase to 15 to 20 MPH, with
gusts to 30 MPH, into this afternoon. Deep mixing heights of 4000
to 6000 feet AGL should occur as well, which will result in
relative humidity values dropping into the 20 to 25 percent range
this afternoon. Excellent smoke dispersal values are forecast this
afternoon.
The gusty winds and very low relative humidity values will result
in elevated fire weather conditions this afternoon. The relative
humidity values could drop a little lower, if deeper mixing
occurs. The middle to high clouds moving in this afternoon may
limit this potential.
