Chances for showers and thunderstorms will continue
through the holiday weekend, especially for the Sierra.
Temperatures will begin to warm each day through the weekend with
well above normal temperatures expected by next week.
Main weather concern through the holiday weekend will be for
thunderstorms each afternoon and evening, especially across the
higher terrain and in the Sierra. No major changes were made to
the forecast this morning.
Chances for showers and thunderstorms today and Sunday are still
looking decent as a weak area of low pressure is expected to
swing across northern California and Nevada. As the trough moves
across the region, temperatures will cool aloft, allowing for
steeper lapse rates and better instability across the region,
especially along the higher terrain. Main impacts from the
thunderstorms will be fairly standard for this time of year. We
are expecting gusty outflow winds up to 45 mph, small hail,
lightning, and brief heavy rain.
Visitors and outdoor enthusiasts are encouraged to keep an eye on
the weather and have a way to receive weather alerts through the
holiday weekend. Have a plan and a safe place to take shelter for
yourself and loved ones for when/if a thunderstorm approaches,
especially if you will be enjoying the mountains or lakes this
holiday weekend. Getting caught out in lightning, small hail, or
even a heavy rain shower is very dangerous. Temperatures can drop
20-30 degrees during a shower and could result in hypothermia.
Bottom line: Be weather aware and safe this holiday weekend.
.LONG TERM...Tuesday through Friday...
High pressure continues to build over northern CA/NV through the
rest of the week with high temperatures reaching into the low 90s
across western NV and upper 70s/low 80s in the Sierra valleys.
Latest GFS is coming into better alignment with the ECMWF showing
a strengthening ridge over the Intermountain West, with
forecaster confidence increasing that we will see above normal
temperatures through the week.
With temperatures rising up to well above normal (10-15 degrees
above average), this will lead to unstable conditions along the
Eastern Sierra and Western NV Sierra Front for the latter half of
the week. There may be a few isolated storms Wednesday, but then
as we get into Thursday and Friday the chances are looking better
for convection. We have added in the mention for slight chance of
showers and thunderstorms mainly along typical favored convergence
zones in Mono-Mineral Counties and along the Highway 395 corridor
from Reno-Carson City to Bridgeport. Hoon
Some patchy FZFG near KTRK again thru 16Z this morning, otherwise
VFR through mid day. By this afternoon, isolated to scattered
thunderstorms will develop, mainly south of a KTRK-KNFL line.
Thunderstorms will be capable of producing small hail, brief heavy
rainfall, and outflow winds up to 45 mph. Storms are possible
again on Sunday as well. Hoon
