Area Forecast Discussion National Weather Service Sacramento CA 131 AM PST Mon Feb 17 2025

SYNOPSIS
Dry weather today, except for a few light morning showers for Shasta County mountains and Lassen Park. Dry weather continues Tuesday, with breezy northerly winds, then another weak system brings mainly light precipitation Wednesday. Dry weather then returns with a warming trend through next weekend with well above normal temperatures.

DISCUSSION
GOES satellite imagery shows a shortwave brushing through far Northern California early this morning. Surface rain gauges show this is bringing some light showers over the mountains of Shasta County and through Lassen National Park. Rainfall in those areas were generally 0.02" to 0.17" over the past 6 hours (at 1AM). The snow profiler at Shasta Dam had snow levels at around 4500 feet, so a there is the potential for some light snow accumulations above that level this morning in those areas. Otherwise, dry weather has returned across the areas and this will continue into Tuesday as upper level ridging builds in. There is some patchy fog developing early this morning around Sacramento Executive Airport, and this is expected to become more widespread around the Sacramento metro area and into the northern San Joaquin Valley, as well as mountain basins. The High Resolution Ensemble Forecast (HRRR) shows a 50% to 80% chance of fog developing in those areas this morning. The fog should disperse by late morning.

Afternoon highs will generally be in the upper 50s to 60s in the Valley today, before warming a few degrees more Tuesday and persisting at those levels into midweek. If clouds clear quickly enough, Tuesday morning may see a return of cooler temperatures, though weak, warming north winds may play a mitigating factor.
While there will be some breezy north winds during the day Tuesday, these have trended even weaker, with gusts generally around 15 mph for the Valley.

Wednesday will see a shortwave track through Northern California.
This will bring light rain and snow showers from early Wednesday morning into the afternoon before tapering off heading into Thursday. This system looks fairly weak, similar to the shortwave that just passed through. Accumulations will be mainly north of I-80 and have trended a little higher with the latest ensembles.
There is a 30-75% chance of a quarter inch of rainfall across the northern Sacramento Valley, a 50-90% over the mountains and foothills north of I-80. The potential for isolated thunderstorms on Wednesday afternoon and evening has diminished, and is now just 5-10%, mainly along the eastern Valley and adjacent foothills.
Overall uncertainty remains regarding the exact track and precipitation amounts but the pattern continues to show minor impacts for portions of the mountains and Northern Sacramento Valley. Latest snow amounts for the northern Sierra are around 1-3" above 6000 feet, so travel impacts look to be limited at this time. Please continue to regularly check back in with the forecast to get the latest updates!

Thursday looks dry as strong upper level ridging builds in, with highs slightly above normal. This is the begining of a fairly strong warming trend. Breezy north winds gusting 20 to 30 mph are possible.

.EXTENDED DISCUSSION (Friday THROUGH Monday)...
Ensemble guidance and clusters following the midweek system continue to have very high confidence in a strong longwave ridge building in across the western CONUS through the end of the week and into the following week, bringing a dry and warm pattern. EFI (Extreme Forecast Index) signals continue to depict above normal temperatures across Northern California, especially by Monday.
There is a 40-75% chance of seeing temperatures above 70 degrees by Sunday and Monday.

Extended forecast outlooks continue to support dry and above normal temperatures forecasted for much of the Western CONUS even into the following week.

AVIATION
Areas of MVFR/IFR/LIFR conditions expected until 20Z due to fog, mist, and low stratus. Afterwards, VFR conditions prevail. Light southerly winds less than 12 kts through this afternoon before becoming northerly later tonight. Sustained west-southwesterly wind to 15 kts along the Sierra crest, with gusts to 25 kts at times through this afternoon.

STO WATCHES/WARNINGS/ADVISORIES
None.
