Service.

.DISCUSSION...Very warm and dry conditions with gusty afternoon
winds will persist across the fire area again Monday, ahead of a
dry cold front which will cross the site Monday evening. Winds
Monday will predominantly be from the west-southwest (250-260
degrees), with the strongest winds along exposed ridgelines and
through wind-aligned drainages during the afternoon and early
evening hours. Overnight recovery is expected to be marginal
Monday morning, allowing RH to fall below 30% by mid morning as
winds begin to develop. As the dry front passes Monday evening,
winds will become northwesterly and remain elevated for a couple
of hours before diminishing overnight. A cooler but dry airmass
will follow for Monday under general northwesterly flow. A further
drying trend will follow for the middle to latter portion of the
upcoming week, with very low daytime RH and marginal to poor
overnight recoveries.
