.DISCUSSION...
Exceptionally dry conditions are forecast around the burn area
today, with mininimum afternoon RH values approaching 20 percent
(or possibly lower). Gusty northwesterly winds will accompany very
dry conditions as well. Recent rainfall and associated higher
fuel moistures should prevent a trifecta of hazardous burning
conditions, however large fire growth will still be possible due
to higher forecast winds this afternoon.
