today will be a transition day between the exiting cold front and the approaching low pressure system with gentle to moderate westerly/northwesterly breezes and infrequent rain showers. Tomorrow's system will bring strong southerly winds with gale force gusts possible, especially for the southernmost marine zones, allowing for wave heights to continue to build through Friday. There is a 25% chance for scattered Thunderstorms over the waters Friday morning-Saturday night.

Synopsis
Precipitation chances persist through the end of the week and into the weekend as a wave exits the region today and the next begins to impact the region on Friday. Mountain snow, rain showers, breezy southerly winds, and isolated thunderstorms will be possible into this evening and then again Friday into the weekend. Dry weather and a return to near to above normal temperatures is then anticipated early to mid next week.
Discussion
As of early this morning, scattered showers remain generally east of I-5 and from I-80 southward. A convergent band of convection, with some attendant lightning, is also being observed across central and southern Shasta County as well. The further southward activity is expected to continually diminish through the morning, with primarily mountain snow showers persisting past sunrise. The convective band in Shasta county looks to follow a similar suit, with heightened, localized impacts. These impacts may include small hail, gusty winds, and moderate to occasionally heavy rainfall rates training over a small area, which could result in minor localized flooding.
As for mountain snowfall impacts through the remainder of today, heaviest snowfall is expected through this morning, with isolated snow showers then persisting throughout the day. Snow levels are expected to drop into the 3500 to 4500 foot range through the morning, before remaining relatively stagnant afterwards. Snow levels with the current activity over the Sierra are, however, in the 5500 to 6500 foot range. As a result, heaviest snowfall is expected above 5500 feet. Additional snowfall accumulations of 6 to 10 inches, up to 15 inches at peaks, will be possible through this morning. Additionally, within the post frontal regime of this system, some weak instability (100 to 200 J/kg) amidst the exiting shortwave this afternoon will result in the potential for some isolated thunderstorm development, primarily for Valley and foothills locations north of I-80. With any thunderstorms that do develop, brief heavy rainfall, gusty winds, small hail, and an isolated funnel cloud or two will be possible.
Despite the look of clearing skies immediately behind this shortwave, the next opportunity for precipitation looks to arrive by Friday morning. An upper level closed low currently off the coast of the Pacific Northwest is expected to deepen along the length of the West Coast through the end of the week and into the weekend as upper level ridging builds from the Gulf of Alaska toward the Pacific Northwest. Even though this system is expected to remain primarily offshore, some attendant weather impacts are still anticipated further inland from Friday through Saturday. Widespread rain, moderate mountain snow, and gusty southerly winds are all expected, with a few isolated thunderstorms possible on Saturday. Strongest winds are expected Friday afternoon and evening, particularly from I- 80 southward, where gusts of 30 to 35 mph will be possible.
As for precipitation, latest trends are hinting at a slight uptick in attendant moisture influx as the system arrives. As a result, forecast liquid precipitation totals have increased a bit, with generally 0.5 to 1 inches possible through the Valley and foothills and 1 to 1.5 inches possible over the Sierra and portions of the Coastal Range through early Sunday morning. Given the influx of moisture and southerly winds advecting in some warmer air, some modest instability, on the order of a few hundred J/kg, is expected to be present Saturday afternoon and evening. While the overall stronger wind field will likely be further southward, some shear will still be possible given the proximity of the closed low. As a result, isolated thunderstorms will be possible on Saturday, primarily across foothills and Valley locations from I-80 southward.
Any thunderstorms that do develop will have the potential for gusty winds, small hail, brief heavy rainfall, and possibly a few instances of funnel clouds.
With the increase in forecast liquid precipitation, increases in attendant mountain snowfall totals are also anticipated. Snow levels look to remain rather consistent, fluctuating in the 3500 to 4500 foot range through the duration of this system, although most accumulating snowfall is expected to stay above 5000 feet at this time. Probabilities of exceeding 6 inches of snowfall from Friday morning through Sunday morning are in the 60 to 90% range above 5000 feet, with 40 to 60% probabilities of exceeding 12 inches of snowfall. Heaviest snowfall, with rates up to 1 inch per hour at times, is expected to occur from I-80 southward. Overall, at this time, looking at snowfall totals of 1 to 1.5 feet above 5000 feet and up to 2 feet at highest peaks. As a result, mountain travel impacts are anticipated from Friday morning through at least early Sunday morning.
By Sunday morning, most organized precipitation activity should be diminishing with only isolated mountain snow showers expected to continue through the morning. Elsewhere, drier weather and likely clearing skies are expected throughout the day on Sunday, with afternoon high temperatures rising into the mid 60s in the Valley.
.EXTENDED DISCUSSION (Monday THROUGH Thursday)...
Drier and warmer weather expected early next week as EPAC upper level ridging builds into the PacNW and offshore flow develops over NorCal. Locally gusty north to east wind possible Monday into early Tuesday in the northern and eastern foothills and mountains. Ridge flattens and progresses midweek as deepening short wave trough approaches the West Coast Wednesday, pushing inland Wednesday night into Thursday. NBM showing slight chance POPs over the Shasta mountains late Wednesday into Wednesday night, expanding into the mountains of Western Plumas County and N Sierra Nevada Thursday. Above normal high temperatures expected through the midweek with 70s in the Central Valley and mainly 40s to 60s for the mountains and foothills.
AVIATION
In Central Valley, lcl MVFR/IFR possible in shra next 24 hrs otherwise VFR. Isolated tsra possible thru 03z Thu. Lcl Sly sfc wind up to 20 kts thru 03z Thu. In foothills/mountains, areas MVFR/IFR with lcl LIFR obscurring trrn next 24 hrs. Isolated tsra possible thru 03z Thu. Snow levels 3500-4500 feet.
