KEY MESSAGES

* Light rain showers continue along and north of Interstate 80 into the afternoon with a low chance of thunderstorms.

* Gusty winds will pose impacts to holiday travel and recreation today and Sunday.

* Below normal temperatures, breezy afternoon winds, and low shower chances are favored next week.

DISCUSSION

A swath of showers will continue to deliver light rain to areas along and north of the I-80 corridor through the morning before tapering in the afternoon. Weak instability from surface heating may allow isolated thunderstorms to develop in the afternoon near the Oregon border, but probabilities of this are only 10-20%. Another windy day is in store today with SW/W gusts increasing to 30-40 mph in the afternoon. Ridge gusts should vary from 45-65 mph throughout the day. Potential wind impacts include rough waters/more hazardous boating on area lakes -- including Lake Tahoe -- and bumpy flights into/out of regional airports.

Drier and less windy weather prevails on Saturday before gusty winds and shower/thunderstorm chances return on Sunday. Highest rain probabilities (30-50%) on Sunday reside from Lassen County to the Oregon border, with a 10-20% chance of thunderstorms in the afternoon. Elsewhere, chances are 20% or less, but may increase (or decrease) depending on the depth/track of an upper compact cyclone and attendant shortwave. Winds become gusty once again Sunday afternoon, renewing wind impacts to holiday travel and recreation. Otherwise, this Labor Day holiday weekend is leaning on the cooler side with daytime highs in the 60s and 70s, which is 10-20 degrees below seasonal averages.

Eastern Pacific troughing is favored to persist next week, extending cooler than normal temperatures, breezy afternoons, and low shower chances through the middle of next week. However, there remains high uncertainty in the prospect of remnant tropical moisture moving northward into the region. Should this happen to some extent, expect shower chances to increase around the middle of next week.

AVIATION

Light rain showers may periodically lower CIGS/VIS to MVFR conditions at KTRK-KTVL through the morning, but shower activity should taper after 15Z. A few showers may pass over KRNO, but chances are lower (~20-30%). Low clouds may lead to mountain obscuration at all terminals today.

30-35 kt SW FL100 winds will maintain potential LLWS and mountain wave turbulence impacts into the evening before winds weaken. SW/W surface gusts are expected to increase to 20-25 kts at Tahoe Basin terminals and 25-30 kts at KRNO-KCXP-KMEV and KMMH in the afternoon.
