SYNOPSIS
* Light Sierra snow showers and gusty winds return Wednesday with a fast moving cold front.
* Cooler with breezy east winds across the Sierra ridges on Thursday.
* High pressure will build in for the rest of the week, bringing warmer, spring-like temperatures this weekend into next week.
DISCUSSION
* Next system is due in Wednesday and continues to look fast with limited precipitation (mainly from Tahoe northward). Still high confidence in a period of strong gusty W/SW winds. Main change was to raise a Lake Wind Advisory for Tahoe/Pyramid Lake on Wednesday.
* Latest satellite imagery showed a ridge over CA-NV with quite a bit of mid-high level cloudiness streaming into the region ahead of the next trough situated near 140W. This trough is forecast to remain an open wave and move quickly through the region Wednesday with much of the guidance bringing light rain/snow showers to the northern Sierra 18-21Z with some spillover across NE CA/far NW NV before precipitation winds down Wednesday evening. Much of W NV and the eastern Sierra of Mono County will remain shadowed. Precipitation amounts look meager, ranging from 0.10-0.25" along the Sierra crest north of Echo Summit and these numbers are already toward the higher end of the guidance with room for this system to be drier. Suffice it to say, snow amounts will be limited to a couple of inches, and being that much of this will fall during the day, impacts to area roads will be limited to brief periods of slush across the higher passes should a heavier shower occur.
* Winds are going to be the biggest impact as a 125+ kt upper jet passes through the region 18-21Z. Ridge level winds increase with gusts likely to exceed 80 mph. Decent mixing along and ahead of this trough and increasing daytime thermal gradients across W NV will result in rough lake waters and bumpy airplane rides. Strong crosswinds for high profile vehicles can be expected along Hwy 395/I-580 with these gusty winds pushing out into the Basin and Range during the afternoon, impacting area highways including Hwy 95 near Walker Lake. Surface winds should begin to weaken as the sun sets, but winds will stay breezy across the ridges as they shift to the NE late Wednesday night into Thursday,
* High pressure then builds late week into the weekend with temperatures warming to 10-15 degrees above normal by Sun-Tue.
ECMWF EFI shows a strong warm signal for both overnight lows and daytime highs with 60s to lower 70s for some W NV valleys and mid 50s for Sierra communities. These conditions may persist through the rest of February under anomalously warm heights.
Some of the ensembles start to show a signal for another system early March, but confidence in the track and timing of systems is very low as the height anomaly shifts northward and allows the potential for some undercutting of the ridge.
Hohmann
AVIATION
* VFR with light winds through the rest of today's operational period.
* Fast moving cold front to move through during the day Wednesday.
there is a 30-50% chance of -SHRA/-SHSN between 18-02Z at KTRK/KTVL with snow accumulation unlikely. Other terminals to remain dry except for maybe a few sprinkles reaching KRNO-KCXP- KMEV.
* WSW winds will increase over the ridges beginning around 12Z, peaking 18-21Z around 45-50 kts and then turning WSW as the trough swings through the area during mid to late afternoon.
Expect moderate to locally severe turbulence, especially for smaller aircraft. LLWS and rotors can also be expected with WSW surface winds 15-25 kts /gusts 30-35 kts/.
