Elevated fire weather conditions possible each afternoon this weekend. * A slight chance of afternoon showers and storms from northeast California into northern Washoe County on Sunday.

The weather today and over the weekend will continue to be hot and dry with highs in the 80s and 90s for Sierra communities and western Nevada valleys, respectively. Brief periods of elevated to locally critical fire weather conditions and choppy lake waters are possible Saturday and Sunday afternoon as winds increase to 15-20 mph with gusts up to 30 mph. A slight chance (10-15%) of afternoon showers and thunderstorms exists Sunday afternoon for portions of Lassen and N Washoe County. A steady warming trend remains favored for the week of July 4th as ensembles advertise an amplified ridge overhead, yielding well above normal temperatures for midweek and beyond. Blended guidance lends a 30-50% chance of reaching 100F Wednesday afternoon for lowest western Nevada valley locales, including Reno and Fallon. From Wednesday onward, daytime highs plateau in the upper 80s to low 90s for the Sierra and upper 90s to 104F for western Nevada valleys into the weekend. Be sure to review your heat safety precautions in preparation for next weeks summer heat, especially if your Independence Day plans take you outdoors! Synoptic scale subsidence within a dry, northwest flow regime will largely prevent convection next week, although a few showers and thunderstorms will be possible Tuesday afternoon from the Tahoe Basin southward where a deformation zone couples with intense differential heating. -Salas && .AVIATION...
