KEY MESSAGES
1. A High Wind Warning has been issued for the Kern County Mountains and Mojave Desert Slopes through 11 PM PDT this evening.
2. A storm system will impact Central California today with mountain snow and thunderstorms which have the potential to extend into the foothills and eastern San Joaquin Valley.
3. Maximum temperatures today are expected six to ten degrees below seasonal averages.
4. A warming trend begins on Sunday and will last through the week ahead with dry conditions.
DISCUSSION
A deepening upper level trough will pass through central California today and push into the southwestern US later this evening. Northwesterly flow aloft in the upstream portion of the trough will result in cooler temperatures across the region.
Afternoon maximums in the San Joaquin Valley and Kern County Desert are expected in the upper 60s to low 70s, around eight to ten degrees below normal for this time of year. High temperatures in the Sierra Nevada and surrounding foothills have the potential to be up to fifteen degrees below seasonal averages.
In addition to cooler temperatures, the aforementioned flow aloft will result in stronger winds across the region this afternoon and evening. Probabilistic guidance from the HRRR expresses a moderate chance (50-70%) for wind gusts to exceed 25 miles per hour in the San Joaquin Valley today. Meanwhile, a Wind Advisory has been issued which includes Indian Wells Valley, Mojave Desert, Piute Walker Basin, the South End of the Upper Sierra, and Tehachapi due to expected sustained winds 30 to 40 miles per hour with gusts possible up to 55 miles per hour. A High Wind Warning is also in effect for the Mojave Desert Slopes as stronger winds are forecast for this area at 35 to 55 miles per hour with gusts up to 70 miles per hour. Both products are valid through 11 PM PDT this evening.
Thunderstorms remain possible in the Sierra Nevada this afternoon which have the potential to extend into the surrounding Sierra foothills and eastern San Joaquin Valley. The following are probabilities for thunderstorms for select areas of the forecast region.
-Sierra Nevada and Foothills- Yosemite Valley 27% Mariposa 26% Oakhurst 26% Shaver lake 26% Grant Grove 25% Lake Thomas Edison 24% Three Rivers 24% Tuolumne Meadows 23%
-San Joaquin Valley- Fresno 21% Porterville 21% Visalia 20% Madera 18% Merced 18% Delano 16% Hanford 16% Bakersfield 15%
Snowfall also remains expected for the Sierra Nevada, with a slight upward trend in totals as snow levels are now projected between 6,000 to 6,500 feet. Accumulations of two to five inches are conceivable above 8,000 feet. There is a low to moderate chance (30 to 50 percent) for localized areas of ten inches or greater in convective bands at the highest elevations of the Sierra Nevada in Tulare County.
As the aforementioned upper level system continues eastward, a zonal upper level pattern is expected to set up. This will bring clear, dry conditions to the region early next week with maximum temperatures on Sunday returning to normals near 80 degrees and exceeding averages by around five degrees on Wednesday.
AVIATION
The Sierra Nevada and Kern County Mountains may have localized mountain MVFR obscurations. The Kern County and Mojave Desert have a high probability of sustained surface winds above 30 KTS through the TAF period. Otherwise, VFR conditions will prevail throughout Central California for at least the next 24 hours.
