.DISCUSSION...
(Today through Tuesday)

WEATHER PATTERN OVERVIEW: An upper-level area of high pressure
will remain parked over the Four Corners region of the United
States today through Saturday. Isolated, dry thunderstorms are
expected in Eastern Nevada this afternoon into this evening. A few
of these thunderstorms could be strong. The primary thunderstorm
hazards will be wind gusts near 50 mph and dangerous cloud to
ground lightning strikes. A warming trend is anticipated Thursday
and Friday. By Friday afternoon, high temperatures will be seven
to nine degrees above normal for this time of year. This type of
heat will result in a moderate risk for heat-related illnesses.
Although heat events like this are relatively common and happen
many times a year, heat-related impacts are possible for those new
to the area if simple precautions are not taken. A Heat Advisory is
in effect for most of Northern and Central Nevada Friday. A Heat
Advisory may be required for Northern Nevada Saturday.

The aforementioned anticyclone aloft will shift southward Sunday
through Tuesday. Monsoonal moisture will move northward into
Eastern Nevada Sunday through Tuesday, resulting in the likelihood
of wetting thunderstorms each afternoon and evening. A cooling
trend trend is anticipated Sunday through Tuesday. By Tuesday
afternoon, maximum temperatures will be around five degrees below
seasonal values.

FORECAST CONFIDENCE & DEVIATIONS: High forecast confidence in
elevated fire weather conditions for Eastern Nevada today. High
forecast confidence regarding a warming trend Thursday and Friday.
High forecast confidence in a Heat Advisory for most of Northern and
Central Nevada Friday. Moderate forecast confidence regarding
wetting thunderstorms in Eastern Nevada each afternoon and evening
Sunday through Tuesday. No deviations from the NBM model output.

Nevada this afternoon into this evening. A few of these
thunderstorms may be strong. The primary thunderstorm hazards
