.DISCUSSION...

Typical June warmth persists through midweek, characterized by
daytime highs in the 70s and 80s areawide. Minimal change in the
governing weather pattern maintains a daily 10-30% chance of
afternoon showers and thunderstorms in the Sierra/higher terrain of
Alpine and Mono County, and portions of Mineral County. Gusty
outflows winds up to 50 mph, small hail, and occasional lightning
will accompany mature thunderstorms each afternoon.

A pattern change finally occurs at the end of this week as
unseasonably strong high pressure travels from the eastern Pacific
to the Intermountain West. Meanwhile, remnant low pressure will
meander off the California coast most of the weekend before sweeping
across the region early next week. This is will be a slow evolving
pattern change, which will have a couple notable weather impacts for
the region. First, temperatures will steadily climb in response to
the approaching high pressure area and will yield a return of 80 and
90 degree heat Friday through the weekend. As a result, minor and
moderate HeatRisk will develop this weekend in Sierra communities
and lower western Nevada valleys, respectively. Be sure to practice
your heat safety precautions if planning any outdoor activities this
weekend.

The second impact is an uptick in both thunderstorm potential and
coverage is possible Friday onward, reaching a peak either Sunday or
Monday. There is still much uncertainty, but the late week-to-
weekend weather pattern would be favorable for greater thunderstorm
coverage and impacts.
