January 11, 2023 report

January 11, 2023

As of the time of this writing, light rain had spread over the northern half of the San Joaquin Valley. Satellite imagery clearly depicts the latest atmospheric river of air, this time aimed at northern California. The southern limit of the precipitation will be somewhere across the valley, possibly near the Kern/Tulare County line. however, even Kern County could pick up a few hundredths from this latest event as both radar and satellite imagery is showing light rain spreading further south than other model projections. There will be a break in the action Thursday and Thursday night then the unrelentless series of storms will begin anew, possibly as early as Friday afternoon. Satellite imagery over the Pacific Ocean is churning with activity with one storm after another lined up like people entering a movie theater. It appears measurable rain will occur every day from Saturday through Thursday. I’ve been mentioning a possible end to this pattern around the  19 or 20. Models this morning show the storm track will be a bit further south during this time frame, however precipitation will still be to our north. I never thought I’d say this, but we do need to dry out for a while. At this point, I’ll go out  on a limb and forecast dry weather for the 19 or 20 and after for several days.

 

Forecast: periods of light rain likely from Fresno County north today. A chance of light showers south of Fresno County. Mostly cloudy tonight with patchy fog developing after midnight. Partly to mostly cloudy Thursday night through Friday morning. A chance of rain Friday. Rain becoming likely again Friday night, especially after midnight. Rain likely at times Saturday through Monday night. A chance of rain Tuesday through Wednesday

Two Week Outlook:  January 18 through January 24: Model projections for this period show below average temperatures. The strong signature for rain is missing,, however it doesn’t eliminate the chance of rain altogether. We’ll call for a chance of rain during this time frame along with below average temperatures.

 

January:  This model continues the trend of the season with a favorable pattern for rain for California. The best chance of rain in January will be over the northern half of the state. Temperatures will run marginally below average.

 

January, February, March:  This model nudges the storm track further north with near average rainfall for northern California but somewhat below average for central and southern California. Temperatures will run marginally above average.

 

Wind Discussion:  Winds will be generally out of the southeast at 5 to 15 mph at times through Friday. Winds Friday night and Saturday will continue out of the southeast, reaching 10 to 20 mph at times with stronger gusts, especially from Fresno County north.

 

Rain Discussion: Light showers are likely from Fresno County north today with a chance of light showers as far south as the Kern/Tulare County line. Just light amounts are anticipated. That is not the case, however, in the longer term. Models are projecting that from now through the 16th of January another 6 to 8 inches of rain or water equivalent will fall along the Sierra Nevada. On the valley floor, another inch and a half to two inches is projected along the east side of the valley from the Kern county line northward through Merced. Along the west side and the valley portion of Kern County, another half to one inch is anticipated. Medium range models continue to show a continuous stream of storms through the 18. A ridge may build along the west coast around the 19th or 20th to put the brakes on this pattern.
