Area Forecast Discussion National Weather Service Sacramento CA 310 AM PDT Wed Apr 24 2024

Synopsis
Cool and unsettled weather this week. A chance for afternoon showers and thunderstorms over the mountains today. Precipitation chances increase Thursday and Friday as a weather system moves through, best chances in the foothills and mountains.

Discussion
Mostly cloudy skies cover NorCal early this morning as the large closed low to our southwest moves toward SoCal. The large surface pressure difference from 24 hours ago has balanced out somewhat as cooling has spread across most of the region. Correspondingly, onshore winds are much lighter this morning with Travis AFB reporting under 10 kts.

Today will be an in-between systems day for NorCal as upstream short-wave energy approaches from the Gulf of Alaska and the closed low moves into SoCal before heading east to generate the next round of severe weather in the Plains on Thursday and Friday.

Partly to mostly cloudy skies are expected today with cool temperatures - similar to Tuesday's. Afternoon thunderstorm chances are expected to be limited to the northern mountains and the Sierra south of Highway 50.

The next round of more widespread showers for NorCal is expected later on Thursday into Friday as short-wave energy slides southward behind the departing SoCal low. It's still looking like a relatively low-impact system with QPF of less than 0.10" in the valley, and generally around 0.50" or less over the mountains. A few inches of snowfall accumulation will be possible over the higher elevations (snow levels above 6-7k ft) in the Sierra, but travel impacts will likely be minimal.

A return to dry weather with gradually milder temperatures is expected to begin Saturday as riding from the eastern Pacific builds into the region.

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...
Dry weather Sunday as weak short wave ridging moves through interior NorCal. Upper troughing then resides off the West Coast through midweek associated with upper low west of VRISL. This will result in onshore flow with temperatures gradually trending down through midweek. Series of vort maxes progged across interior NorCal Wednesday with NBM showing slight chance POPs over the mountains of Shasta and Plumas counties.

AVIATION
VFR conditions over interior NorCal next 24 hrs exc isolated MVFR/IFR possible over mtns in showers. Sfc wind mainly below 12 kts except vcnty of Delta SWly sust wind up to 18 kts possible aft 00z Thu.
