Several winter storms will impact vacation travel through next weekend – YubaNet


Cold nights with Valley fog and gel continue until Monday. The chances of rain and snow return early this week and become widespread early on Tuesday. A series of storms will continue this threat throughout the week until the holiday weekend with little break in expected precipitation. Mountain trips will be likely be significantly impacted sometimes by lots of snow. Periods of gusty winds are also possible across the region.

Discussion

The last IR satellite imagery indicates an area of ​​low cloud over the delta and valley from the vicinity of Redding to the south. Most come in the form of weak stratus cloud. Some unequal fog has been observed in a few places but visibility was generally a little better than last night. It is likely due to the persistence stratus new fog training. Low cloud could again persist for much of the day today in the valley and delta. The foothills and mountains will have better potential for seeing sun today. No more morning fog is expected again Monday in the Valley. Temperatures at 3 a.m. PST were not as cold due to the greater cloud cover, about 3 to 9 degrees cooler than yesterday. An exception to this is Modesto, which was 33 degrees. Some gel is possible in parts of the valley, delta and foothills. In the mountains, morning lows will range from 30s to teens at higher elevations with snow cover.

High temperatures today will remain fairly cool, around 4 to 8 degrees below Ordinary. Daytime highs will be between 40 and 50 in the valley and foothills and between 30 and 40 in the mountains.

the higher level the pattern starts to change at the beginning of this week as together orientation remains in agreement with a cold hollow Gulf of Alaska deepening over the eastern Pacific.

the hollow The axis is expected to linger just off the west coast for most of next week with several shortwaves moving towards northern California with a humid southwest to flow persistent. This will bring several rounds of rainfall across the region, likely significantly disrupting vacation travel.

The system continued to slow down, with just one little chance of some precipitation over western Shasta County today through Monday morning. From Monday evening to Tuesday, the first wave arrives, bringing widespread mountain rain and snow. Snow levels are expected to be around 3000-4000 feet.

Sets suggest that snowfall amounts through Tuesday night could reach around 6 to 12 inches for elevations of 6,000 feet and above. Heavier precipitation spreads Wednesday with better subtropical climate humidity tap, but snow levels will also reach about 4,500 to 6,500 feet. This means that the impacts of the trip will be more concentrated on higher terrain, with up to a few feet of additional snow possible around the Sierra passes.

Extended discussion (Thursday to Sunday)

Cluster analysis and sets continue to represent persistent deep troughs that settle just off the west coast over the extended period. This pattern will favor a period of precipitation lasting several days as several pulses move through the interior of NorCal. Overall, rainfall amounts could range from 1 ″ to 1.75 ″ in the valley with 2 ″ to 5.5 ″ possible in the foothills from Thursday to Sunday morning.

Snow levels will generally be between 3,500 and 5,000 feet on Thursday and then drop to around 2,000 to 3,500. pi Friday in the weekend.

Together odds are high for several feet of mountain snow with snow totals in the range of 2 to 6+ feet in the Sierra Nevada and southern Cascades from Thursday to Sunday morning. Some snow accumulations could even extend to the upper foothills.

Gusts of wind are also possible, which could reduce visibility in mountain snow. There might even be potentially downed tree branches in the valley and the foothills.

Holiday travel disruptions are likely with the potential for chain checks, significant travel delays and possible road closures. Stay tuned for forecast updates.
