Warm and dry conditions through next week. Lighter north winds continue into early next week, with increasing temperatures and hot weather possible by the middle of next week.
Discussion
Generally clear skies and near normal low temperatures expected through this morning. Around midnight, a few stronger gusts are noted in higher terrain and favored gaps/canyons around the area; otherwise, gusty winds have mainly diminished in the Valley.
Northerly winds continue today as upper level troughing continues over the area. Winds will be much lighter than those seen yesterday, although some gusts from 20-25 mph will be possible mainly in the northern Sacramento Valley and over the mountains. A couple of shortwaves drop into the Central Great Basin/Central Rockies Sunday into Tuesday, keeping weak northerly winds in the forecast during this time.
With continued low daytime humidity and locally poor overnight recoveries expected through early next week, some elevated fire weather concerns are still noted across much of interior Northern California.
A warming trend will continue this weekend into mid-next week with daytime highs creeping up a few degrees each day. Highs today will be a few degrees warmer than those of yesterday with mid to upper 80s expected in the Valley this afternoon, and mountain highs in the upper 50s to 60s.
By Tuesday, Valley highs will be in the upper 90s with some local values in the triple digits.
Extended Discussion (Wednesday through Saturday)
An upper ridge will be overhead of Northern California on Wednesday, bringing in the warmest temperatures of the week. Widespread triple digits are expected across the Sacramento Valley with upper 90s in the northern San Joaquin Valley.
A trough will deepen off the coast on Thursday, helping to push the main ridge east and cool temperatures as much as 5-10 degrees for Thursday. Clusters indicate much uncertainty in the timing of this trough for late week into the holiday weekend.
The main impacts with this trough would be cooler temperatures, onshore winds, and possibly a few showers. NBM continues to indicate the most likely location for any showers would be over Shasta County, sometime after Thursday evening.
