November 13, 2023 afternoon report

November 13, 2023

Summary:  A low pressure system which yesterday was off the coast of the Pacific Northwest, has cut off and is now located roughly 600 miles west of the Golden Gate. Since this is not a cut off low situation, this system will have very weak steering currents so most models show it in a stationary position several hundred miles off shore. The low will pinwheel bands of energy from southwest to northeast. Most models show a batch of energy moving from southwest to northeast through central California Wednesday night and Thursday. This will be our first shot at precipitation. there will be a chance of rain any time from Thursday night through Saturday. The low will finally move through central and southern California Friday night and Saturday. A large ridge of upper level high pressure will begin moving inland Sunday, building a ridge all the way to the Pacific Northwest and central Canada for several days of dry weather. The amount of precipitation that falls on the valley floor will determine whether or not we see our first bout of night and morning fog.

Forecast: Mostly clear with occasional high clouds tonight and Tuesday. Increasing cloudiness Tuesday night. Mostly cloudy Wednesday. An increasing chance of rain Wednesday night. Rain likely Wednesday night with a chance of rain at any given time from Wednesday night through Saturday evening. Mostly cloudy Saturday night through Sunday morning. Becoming mostly clear Sunday afternoon through Monday with patchy morning fog.

Winds: Winds tonight to Tuesday will be generally at or less than 6 mph with periods of near calm conditions. Winds Tuesday night through Wednesday night will be generally out of the east to southeast at 5 to 15  mph. Winds over the valley portion of Kern County will increase out of the east to southeast at 10 yo 15 mph. gusts to 40 mph will be possible near the base of the Tehachapi Mountains, decreasing Thursday morning.

Rain: Conditions will remain dry through probably Thursday morning. The first band of precipitation will move through Wednesday night and Thursday. there will be a chance of rain at any given time from Wednesday through Saturday evening. Since we have a cut off low situation, rainfall amounts will vary widely, but will generally range from .25 to .33 through Thursday with perhaps another .25 or so from Thursday night through Saturday. The wild card in all this is how far off shore this storm remains. If it stays too far off shore, rainfall amounts will be greatly reduced.    

Frost:  All locations will be above freezing tonight and each night for the next seven days.
