The episode as NWS HNX wrote it up.
A moisture deficient trough moved through central California on November 18. This system did not have much precipitation with it as some stations from Fresno County northward picked up a tenth of an inch or less of liquid precipitation. However, the system did produce a period of increased winds as a result of a strong pressure gradient during the afternoon and evening of November 18 over mountains and deserts of Kern County. Several stations measured gusts exceeding 45 mph and a few low impact stations had gusts in excess of 60 mph.

NWS Hanford, CA wrote its last area forecast discussion before the first event at Nov 18, 1:36 AM PST, 8 hours 51 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Hanford CA 136 AM PST Mon Nov 18 2024 && .KEY MESSAGES... 1. A weak system through Monday morning has a 15 to 45 percent probability for at least 0.01" of rainfall from Fresno County north. There is also a 40 to 60 percent probability for at least 1 inch of snow, mainly above 7000 feet, around Yosemite NP. 2. A Freeze Warning is in effect from Monday Night through Tuesday morning for the rural portions of the San Joaquin Valley, with lows as cold as 30 degrees forecast. 3. Temperatures trend warmer with highs a few degrees above average late in the week. 4. Confidence is improving for a stronger system to approach 4he region next weekend into early the following week that would bring heavier precipitation to central California. && .DISCUSSION... A system passing through Northern California this morning will bring precipitation to the region, as well as gusty winds through and below pass level in Kern County through the day. The moisture is displaced to our north, so QPF totals across the region will be quite limited to just a couple hundredths of an inch north of Fresno County. In the Sierra Nevada, very light snow is forecast. Currently looking at a 22% probability for 1 inch of snow ore more at Tioga Pass for this event. Strong onshore gradients will keep wind gusts elevated on the lee slopes of the Tehachapi Mountains through the afternoon today.The Wind Advisory for the lee slopes remains in effect through 2 PM this afternoon. This gradient will relax overnight Monday night and into Tuesday, leading to a decrease in wind gusts. As the winds weaken due to the system exiting the region, there will be less mixing Monday night/Tuesday morning. For us, that will lead to colder overnight lows. The Freeze Watch for the rural portions of the San Joaquin Valley has been upgraded to a Freeze Warning. NBM probabilities show a 50% - 90% probability of morning lows being at or below 32 degrees Tuesday morning. In other words, slightly higher confidence for freezing morning lows compared to the frost/freeze event we had last Sunday morning. Wednesday through Friday will feature a warming trend across the San Joaquin Valley, with highs being several degrees above normal by Friday - low 70s as afternoon highs. This trend will be mainly attributed to high pressure axis forming over the Four Corners region. The northern most periphery of our forecast area has the potential to see off and on rain through this time period due to what looks like a significant storm system impacting Northern California. Ensemble guidance is getting more confident that the aforementioned storm system impacting NorCal will makes its way south Friday evening into Saturday. This storm has more than enough precip with it to bring another wetting rain across Central California. Snow levels are projected to be above 8,000 feet on Saturday, as this looks to be a warm storm system. In the extended period through early next week, an active jet pattern is conceivable, meaning more valley rain and mountain snow for Central California. This is further supported by the CPC's 6-10 outlook showing a tilt in the odds towards above average precip compared to what's normal for mid to late November. && .AVIATION...Light winds and VFR conditions will prevail thru the period at all terminals. Mountain obscurations possible along the windward slopes of the Sierra during the overnight hours. && .AIR QUALITY ISSUES... On Monday November 18 2024, Fireplace/Wood Stove Burning Status is: No Burning Unless Registered in Fresno County. Burning Discouraged in Kern, Kings, Madera, Merced, and Tulare Counties, and Kern (Greater Frazier Park Area) and Sequoia National Park and Forest. && .CERTAINTY... The level of certainty for days 1 and 2 is high. The level of certainty for days 3 through 7 is medium. Certainty levels include low...medium...and high. Please visit www.weather.gov/hnx/certainty.html for additional information and/or to provide feedback. && .HNX WATCHES/WARNINGS/ADVISORIES... Wind Advisory until 2 PM PST this afternoon for CAZ338. Freeze Warning from 10 PM this evening to 10 AM PST Tuesday for CAZ302-303-305-306-309>312-315-316. Cold Weather Advisory from 10 PM this evening to 10 AM PST Tuesday for CAZ323-328-330. && ab weather.gov/hanford
