Cooler and possible wet weather as expected! Already liking the 10 degree drop.

Monday Sept 8 - Thursday Sept 11 - The trough off the coast deepens and moves onshore early next week, with daytime temperatures cooling to in general 5-10 degrees below normal. Along the coast, extensive marine layer clouds are expected each morning with breezy onshore winds in the afternoons. A cold front associated with the trough is expected to bring rain and rain showers across the North Coast Sunday night into Monday. A few rain showers could reach as far south as North Bay Monday. There is also a slight chance for afternoon thunderstorms to develop across the North Monday afternoon, with the highest chances over elevated terrain. Chances for precipitation continue Tuesday through Thursday as additional weather systems move through the northern part of the territory, with chances for isolated thunderstorms across the North Tuesday and Wednesday, with chances shifting eastwards into the northern and central Sierra mid-next week. Across the southern part of the area, mostly dry conditions are expected early next week, but chances for showers/thunderstorms over the Sierra increase mid-next week as the trough moves eastwards.

Fri Sep 12 – Mon Sep 15 - Apart from continued chances for showers/thunderstorms over the Sierra, slightly warmer and drier weather is expected late next week. However, additional weather systems may approach the territory and bring a chance of precipitation next weekend, details uncertain.

‘Unusual’ storm delivers 100s of lightning strikes

The Plumas National Forest reports that it took hundreds of lightning strikes in less than 24 hours from thunderstorms that formed Sept. 2 and continued with unusually strong storms into Sept. 3. The storms were generally wet, with some areas receiving heavy rain. However, more lightning fires are likely from all of the activity, reports the forest.

PNF firefighters responded to six new lightning fires across the forest. The three new fires on the Beckwourth Ranger District are contained, bringing the total number of fires since Aug. 24 up to 42, with 40 confirmed lightning fires. The largest fire of the 42 is approximately 2.75 acres. No communities or structures are threatened at this time.

“There are national forests in California and across the Western United States that are dealing with large fires right now,” said PNF Fire Management Officer Martin Senter. “So far the Plumas has been fortunate that we have been able to keep fires small and provide firefighting resources to help on the larger incidents.”

Will be interesting to see how this holds together. Usually these early systems have a large boom/bust potential. This year the relative lack of strong HP would lean more towards the weightier precip totals.
I do think there will be very little precip south of Chico and not much at all in the valley. There will be some stronger winds in the SJV.
We looks to be back to a trough pattern with some lows rotating through. Each of these will bring a chance of showers and thunderstorms.
What is interesting is beyond the “extended”. As Anvilhead pointed out there are some large scale pattern impacting events that will make long range forecasting hard.
What is interesting to me.. is the lack of HP driven North wind events. We have usually had one by now in NOPS and a significant fire weather or fires with it.
Watching how this pattern is evolving a ridge builds in by the middle of the month and a short duration light offshore wind event looks evident, but not (yet anyway) even a moderate event. The HP looks to be more of a summer like pattern with the 4 corners high establishing.
This sub tropical ridge placement would be very La Niña like and considering that we are teetering between a weak and neutral La Niña, that would reason out. A ridge in the south setting up and keeping the jet stream fro sagging beyond the middle of the state.
The shoulder seasons are the most difficult to predict so not putting much stock in it.. but the pattern is interesting.
Some of our biggest flood years have been when patterns like this set up over winter.. especially early in the winter.

Since about 3pm a series of storms has been tracking north through Scott Valley and Seiad Valley. Abundant lightning showing on the radar from marble mountain wilderness up through the Klamath river. Ft Jones camera was up and running before the storms moved through and now is no longer responding after significant lightning went through the area. There appears to be decent precip with it in spots but not everywhere. Gusty outflow winds are being observed near ICP in Happy Camp. This type of weather was not included in today’s fire weather forecast for either incident so it is somewhat surprising.

Thats a bummer bcuz it was / has been noted (for more than just today) in the GACC 7day

I have to digress on the forecast, as reviewing the FWF for the incident it does state 10% chance. 10% chance turned into 100%

Definitely looking & sounding very convective now to the west, north & east of RDD. We’ll see how it all fills in and how it drifts/drags/converges over and around the valley. Hoping for rain everywhere and hoping for no new fires bcuz “wind season” (my term) is fast approaching if not already upon us AND it could still heat up enough to be a pain in the butt for Rx activities


Edit: Update - As of 1527, the Special Weather Statements have begun.
Its rocking for sure in the RDD. Hang on to your butt’s!! :wink:
