.DISCUSSION...
An upper ridge will be building into the region over the next few
days. This will push temperatures above normal through the
weekend and into next week. A weak wave moving through the ridge
will produce scattered thunderstorms today and Sunday afternoon
and evening. Overall fire weather concerns remain low through the
weekend, with minimum humidity above 30% and good overnight
recovery. Toward the middle of next week, concern may increase
with the airmass drying out and temperatures approaching 100 by
Wednesday.
