Well, the atmospheric river event dumped 2-4” of rain along the coast this weekend and 4-7” of rain in the Coast Range. This drove up the rivers and caused the Trask and Wilson Rivers to quickly reach Minor Flood stage. The Kilchis River does not have gauges but did also cause some flooding. Fortunately, the rivers went down pretty quickly as the North Main (Hwy 101) area was closed until the flooding subsided Saturday.
Then, another cold front went thru yesterday and that dropped the temperatures pretty quickly. The low at the airport dropped to 34 last night and there were freezing temperatures and snow up at the passes. Fortunately, the temperatures slowly raised overnight thanks to a southwesterly flow over the area. We still see the large low pressure area that generated all the showers, drifting southward towards northern California and this will keep us with a chance of showers, with possible thunderstorms still, until around midnight, then the shower activity becomes more widely scattered as a high pressure ridge moves in.
So, this evening, we see mostly cloudy skies with a chance of showers, with possible thunderstorms still, winds easterly 4-8, the low tonight near 35. There is a chance of rain/snow mix across the summit, but accumulating snow is likely up around 2500’.
The ridge continues to move across so the forecast for tomorrow looks mostly sunny and with the colder east winds 5-10, the high near 47. With the colder temperatures spilling in from the east, combining with radiational cooling with the partly cloudy skies, the lows drop down to near 32.
The high brings sunny skies Wednesday with calm winds, the high temperatures near 48. The area sees partly cloudy skies again Wednesday night, calm winds, lows near 34.
The colder air remains in place Thursday with partly sunny skies, the high near 50, cold again that night, lows near 33. After Thursday, the models head down different roads, some show the area staying cooler and dry, while some of the others suggest the rain and/or rainshowers return.
So, for Veteran’s Day (Friday), and for Saturday, we go with mostly sunny skies, a slight chance of showers, the high near 49, then mostly cloudy skies that night with the low dropping to near 33 again.
Partly sunny skies Sunday, a slight chance of a shower or two, highs near 49, lows near 34.
