.DISCUSSION...

High pressure Sunday gives way to a weak, dry cold front Sunday
night into early Monday. Look for relatively mild temperatures,
with afternoon RHs in the upper 30s to mid-40s and fair recoveries
at night. Winds are forecast to be out of the west to southwest
most of the time, though eastern reaches of the site could see
east to southeast winds Sunday afternoon. Speeds are forecast
to increase Sunday night into Monday morning with the
incoming dry cold front, decreasing some Monday afternoon but
some increased downslope could increase them again for early Monday
evening. Continued dry weather and relatively mild temperatures
through Thursday, with light winds terrain driven winds. Light
rain and snow shower chances and cooler temperatures by late
Friday into next Saturday with cooler reading and gusty winds,
with possible freezing temperatures possible by Friday or
Saturday morning.
