Plan on quiet weather with warm temperatures through Friday. An early season storm will bring periods of gusty winds with increased fire danger and much cooler temperatures this weekend. Some light rain showers are expected by later this weekend.
Warm days with cool nights to continue through the end of the work week along with afternoon and evening breezes, especially Friday. Smoke and haze will be lingering about as wildfire activity persists.
Big changes are still on track for the weekend with a strong cold front dropping through the region. Here are the details:
WINDS: Winds will start to pick up on Saturday, and even more so on Sunday with travel difficulties, choppy lake conditions, and areas of blowing dust possible. Winds will elevate the fire danger so fire weather watches remain in effect. Please see the fire section below for additional details. We're expecting gusts 25-35 mph on Saturday and 30-45 mph Sunday, with locally stronger gusts 50+ mph in wind-prone locations.
TEMPERATURES: Falling temperatures will have it feeling like fall! There will be about a 20 degree drop in daytimes highs on Sunday- Monday. The clouds, wind, and the potential for rain will contribute to making it feel even colder on Sunday. Frosts and freezes are possible for outlying rural areas and suburban valleys Monday through Wednesday mornings. Remember to protect your sensitive vegetation if your outdoor gardens are still flourishing.
RAIN/SNOW POTENTIAL: Best chances for rainfall will be near and north of I-80 Saturday night into Sunday with lighter rain possible further south. Check back for updates as we dial in on the rainfall totals. A few flakes are possible above 10,000 feet, but accumulation is unlikely. If an NCFR develops or the cold front becomes convective, then we could easily see a short-lived, intense period of precipitation and lower snow levels than currently forecast.
THUNDERSTORMS: There is a 15% chance for thunderstorms to develop in northeast California, possibly as far south as the Tahoe Basin, on Sunday as the cold and unstable portion of the low moves overhead.
OUTLOOK FOR NEXT WEEK: Ahh the transition season . where the forecast models struggle with longer range forecasts. Simulations for next week are definitely falling prey to this time of year. The longer range ensemble cluster 500 mb heights continue to show variations between another trough dropping into the region and a strengthening ridge. Large NBM temperature spreads are indicative of the uncertainty as well. Still looking at low predictablity for the middle into the end of next week.
Areas of haze from wildfire smoke will continue to impact slantwise VIS today; however, surface visibility should remain primarily VFR for terminals. For areas in the vicinity of the Dixie and Caldor fires, smoke may obscure some terrain.
Light breezes with gusts up to 15-20 kts this afternoon and evening are expected to increase Friday with peak gusts 20-25 kts.
Big changes are approaching for the weekend with strong winds, wind shear (above 2 kft AGL with at least pockets of LLWS), and turbulence likely. There is also increasing potential for rain and lowering CIGS/VIS.
No major changes to the ongoing forecast.
Strong cold front will bring big changes in the weather for the weekend. Winds begin to increase along the midslopes and ridges late Friday, with gusty winds forecast for Saturday and Sunday. Southwest to west wind gusts 25-35 mph on Saturday afternoon and evening will combine with very dry conditions east of the Sierra to produce areas of critical conditions. Fire Weather Watches remain in effect for for Saturday for areas near and north of US-50. Wind gusts will be a bit less (20-30 mph) and along with the higher humidity (20-30%), we refrained from a watch for the Tahoe Basin and fire zone 271 (western Lassen/Plumas).
Saturday night winds will weaken for valley areas, but will likely remain elevated for the midslopes and ridges. Stronger winds are expected on Sunday with the latest ensemble guidance hinting at widespread gusts 35-45 mph and wind prone areas possibly reaching 50+ mph. The primary limiting factor for fire weather concerns will be the increasing humidity values and the potential for wetting rains. Areas near and east of US-395 and south of US-50 won't be as fortunate and humidity values are not expected to increase until later in the day. Fire Weather Watch for gusty winds and low humidity remains in effect for those areas on Sunday. Another factor to consider with the increasing winds will areas of blowing dust and burned debris and/or ash. Visibility may be impacted in the vicinity of fires as any burned particles or ash become lofted by the strong winds ahead of the rain potential.
Rain is looking increasingly likely for areas near and north of I-80 Saturday night into Sunday. Lighter showers will be possible for areas south of Interstate 80. High confidence continues for wetting rain (0.10"+) across northeast California into the Tahoe Basin and for northern Washoe County. There is still a bit of uncertainty with the amount of rain that will occur as this will rely heavily on the cold front's ability to hold together as it drops southward.
There is still a 15% chance for thunderstorms in northeast California and potentially as far south as the Tahoe Basin on Sunday. Just another factor to monitor which could threaten firefighter safety at ongoing wildfires.
Solid cooldown behind the front with about a 20 degrees plummet in temperatures. Firefighter crews working overnight or sleeping outdoors will have to keep an eye on those colder temperatures as some frosts/freezes will be possible. Winds to shift N-NE behind the front on Monday. A major shift in winds will be a watch out situation for ongoing fires, especially since it can be a critical fire pattern for western Sierra slopes. -Edan
