Marine Weather and Tide Forecast for Squaw Valley, CA

DISCUSSION
Seasonal temperatures with breezy conditions will continue until Monday for the region as we remain on the back side of the inside-slider trough. Although, winds have been decreasing in the Kern County mountains and desert. We will let the wind advisories and the High Wind Warning expire later this evening in these areas. However, increased winds (gusts 30-40 mph) have been locally occurring in parts of the Sierra Nevada and foothills, including near North Fork/Bass Lake, per a local weather spotter. This will pick up a bit overnight tonight, but decrease by early Monday morning. The probability for a 40 mph gust in this particular area is about 50-60 percent through early Monday morning. Winds combined with low humidity will continue on Monday across the SJ Valley and adjacent West Side Hills/Coastal Ranges, although the winds won't be quite as strong compared to today and yesterday. Thus, will allow the Red Flag Warning to continue until Monday evening for these locations.

A marked warmup occurs Tuesday through the end of the week, as highs touch 90 degrees in much of the Central Valley. The Kern County desert locations will see a return of 90 degree readings beginning Wednesday. Highs in the warmest locations reach the mid to upper 90s by Thursday, and temperatures will remain steady or a touch lower until next weekend. Moderate to high probabilities exist for widespread readings at least 95 degrees in both the San Joaquin Valley and Kern County desert for this period. Triple digit heat has a low probability to occur in these areas Thursday and Friday, but cannot be ruled out in the warmest locations. Unfortunately, daytime humidity will lower a bit more with the warming during the latter part of this week.
Thus, the risk for large grass fires will continue for much of this week with the potential for rapid spread.

Overall, a warm and dry pattern will occur for much of this coming week.


AVIATION
VFR conditions will prevail for the next 24 hours.

FIRE WEATHER
Low minimum relative humidity (RH) values combined with breezy conditions in the San Joaquin Valley and the West Side Hills along the Coastal Range continues the threat for fast-moving grass fires on Monday. A Red Flag Warning remains in effect for this area until 8 PM Monday as minimum RH values under 15 percent are anticipated and will continue a Major Risk for Fire Danger. Although, winds will not be quite as strong on Monday compared to the previous couple of days. Drier and warmer air is expected to move into central California later this week with minimum RH values at lower elevations expected less 15 percent for multiple days in a row. At least an elevated risk for fire weather persists this week. In addition, poor to moderate overnight humidity recovery will also occur across the region for the latter part of this week.

AIR QUALITY ISSUES
None.
