...BREEZY, WARM, AND DRY MONDAY. COOLER BEHIND POSSIBLE COLD FRONTAL
PASSAGE ON TUESDAY...

Upper trough along the coast will push a surface cold front inland
Monday, possibly passing through the fire area Tuesday.  Pre-frontal
drying and warming southeast wind will increase over the fire area
Monday, then shift to cooler, moister northwest wind Tuesday behind
the front, if it does pass through.  In our judgment the front will
more likely stall west of the fire and warm, dry, southeast wind
will continue into Tuesday.  Therefore, please consider Tuesday's
forecast (below) subject to change.  We suggest requesting another
forecast tomorrow for Tuesday.
