.SYNOPSIS...Near normal temperatures with some afternoon clouds and
mountain showers for the rest of the weekend. Lingering rain chances
decrease and temperatures increase as high pressure takes control
for the rest of the week...with temperatures rising to 10 degrees
above normal by late week.
.SHORT TERM...Today through Monday.
Upper level low continues to drift across the area. With limited
dynamics and moisture, only expecting a few showers, possible a
rumble of thunder or two on the mountains. Latest guidance wraps
better moisture around the north and west sides of the upper level
low as it begins to depart the area on Monday. Went ahead and
continued PoPs in the Southern Great Basin through Monday,
otherwise, little changes made to short term forecast.
.LONG TERM...Tuesday through Friday Night.
After the upper level low from the short term departs, a strong
ridge builds in and cranks up the heat, possibly giving the area the
first widespread triple digit readings this year. Very similar
differences in models still exist with the Euro building the
strongest ridge. Most guidance remained the same, though did nudge
temps up slightly in the long term to account for a stronger,
lingering ridge. Temperatures will start the week near normal, and
gradually warm through the week, with the warmest days Wednesday -
Friday reaching around 10 degrees above normal. Given the cool
spring thus far, the warm up could prove to be dangerous, especially
if the ridge remains in place longer than currently progged.
.AVIATION...For McCarran...East to southeast winds will increase to
around 10 kts with occasional gusts to 20 kts. Transition to
southwest will occur early this evening. Winds should diminish after
03Z and favor typical drainage flow by late tonight. After
light/variable winds early on Sunday, southeast winds should return
by afternoon. A stray shower is possible in the Spring Mountains on
Sunday, but only mid and high clouds are expected at the terminal
through the period.
For the rest of southern Nevada...northwest Arizona...and southeast
California...For the southern Great Basin and Inyo County, chance
for scattered showers and isolated thunderstorms, especially during
the afternoon and early evening hours today and Sunday. CIGs 070-
100 are possible in vicinity of precipitation, with occasional
mountain obscurations possible. Erratic/gusty winds near showers.
For the rest of the area, some mid and high clouds with breezy S or
SE winds during the day and lighter and more variable flow at night.
.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather according to standard operating procedures.
Short Term/Long Term...Steele
