Marine Weather and Tide Forecast for Sunnyside-Tahoe City, CA

DISCUSSION

Breezy E/SE winds this afternoon with gusts 25-30 mph may produce minor fire concerns in far northeast CA/northwest NV, and also in Mineral County. While most areas should see these winds diminish tonight, a small area of enhanced SE-S winds (gusts 30-35 mph) is still indicated over Mineral and SE Churchill counties overnight into early Saturday morning, bringing a short period of choppy conditions on Walker Lake.

Lighter winds then prevail through most of the weekend, except for a return of modest zephyr-type southwest/west breezes (gusts 20-25 mph) Sunday afternoon. Temperatures this weekend will rise into the mid-upper 70s for lower elevations and near 70 degrees in the Sierra.

For next week, an approaching storm from the eastern Pacific is expected to bring increased S-SW winds Monday afternoon, although the latest guidance is trending slower with this storm's approach toward the west coast. This would delay the onset of winds and also cap the speeds a bit with gusts more in the 30-35 mph range from the Reno-Tahoe areas northward to the OR border. These winds with ongoing dry conditions could lead to a period of elevated to locally critical fire weather conditions Monday afternoon.

For the remainder of next week, this storm appears to show a greater potential of stalling offshore Tuesday and reducing shower chances across the region. Then from Wednesday through Friday, a more varied storm track continues to limit confidence in rain and mountain snow chances/amounts, especially north of I-80.
Currently the eastern Sierra and Tahoe are favored with 50-70% chances centered on Wednesday, but dropping to a broader 25-50% elsewhere. Showers could linger or even have a delayed onset until later next week, as some scenarios hold the low offshore before finally moving inland as a weaker system. A few wetter outcomes are still within the realm of the ensemble guidance ranges, but at this time a less significant precip event is more likely next week. Cooler temperatures are still on the table next week from Tuesday onward, with highs generally in the upper 50s-mid 60s for lower elevations and lower-mid 50s for Sierra communities. MJD

AVIATION

East FL100 winds of 30-35 kt will maintain mountain wave turbulence concerns along and west of the Sierra crest until these winds decrease later this afternoon. For the main terminals, east-southeast wind gusts generally below 20 kt continue through 02-03Z this evening, except KCXP/KMMH which are more prone to increased winds from this direction could see gusts up to 25 kt.

VFR conditions prevail through the weekend with light winds prevailing Saturday, then southwest breezes with gusts 15-20 kt return by Sunday afternoon at the main terminals. MJD
