November 9, 2019 – Dry and mild weather pattern continues into next week.
Patchy fog will be possible once again this morning in the Delta region stretching south down I-5 to north of Modesto. Any fog that does develop will be very shallow and will burn off quickly once the sunrises. The upper level ridge will flatten a bit today as a deep trough digs into the Central US. This will bring some high clouds to the region by the mid morning into the afternoon. Locally breezy ridgetop winds are expected Sunday night into Monday as the trough continues to dig to our east and a ridge builds back in over northern CA. High clouds will continue to pass over the region into Monday.
Above normal daytime highs will continue this weekend into early next week with near normal overnight lows.
Extended Discussion (Wednesday through Saturday)
The dominant Eastern Pacific Ridge might flatten a little mid week. Although no rain chances are expected to reach California, this could help to cool temperatures a bit and increase the moisture in the airmass slightly.
Late in the week, models are trying to pull in a chance of some light precip to the far northern portion of California. Confidence is low as ensemble guidance only has a few members indicating measurable precip.
Ridge rebuilds late in the weekend for a return to dry weather with mild daytime temperatures.
