Area Forecast Discussion National Weather Service Sacramento CA 216 PM PDT Fri Oct 30 2020

SYNOPSIS. Dry conditions with above normal temperatures will continue through the weekend and into early next week.

DISCUSSION. Like a broken record from yesterday . GOES-West visible imagery reveals clear skies throughout northern interior California. As of lunchtime, temperatures are generally running within a few or several degrees from what they were this time yesterday. The airmass remains very dry, and as a result, large diurnal temperature swings will continue with highs warming this afternoon to the upper 70s to low 80s throughout the Sacramento Valley and northern San Joaquin Valley. This equates anywhere from about 5 to 15 deg F above late October climatological normals. For comparison, the normal October 30 high for Sacramento Downtown normal is 71 deg F and 70 deg F for Redding Airport.

Upper level high is positioned just west of the California coast this afternoon with an upper level low off the Baja California coast (Rex Block setup), and will remain quasistationary for the next several days. A shortwave trough rippling through Pacific Northwest will help to promote a brief period of locally gusty north/east winds late tonight and Saturday morning, mainly along the west side of the Sacramento Valley and portions of the northern Sierra Nevada. Not expecting anything widespread, nor anywhere close to the magnitude/duration earlier in the week, but nonetheless a brief period with elevated fire weather concerns. Wind gusts will be generally limited to around 15 to 25 mph in locations that do experience breezy conditions. Another abbreviated period of north/east winds will develop again Saturday night and Sunday.

Halloween will be dry with highs around 80 deg F for Valley communities. Temperatures on Halloween evening will drop into the 60s and through the 50s as the late evening progresses. Lows will bottom out in the 40s by sunrise Sunday. Minimal day-to-day changes in lows and highs are expected through the weekend and into early/middle next week.

Rowe

EXTENDED DISCUSSION (Tuesday THROUGH Friday). Around Tuesday the upper level ridge just off the California coast will flatten and help to break up the Rex Block. Upper level flow will become more zonal over northern California by the middle of next week. During this time, a storm system will impact the Pacific Northwest with precipitation chances extending south to extreme northwest California. The Sacramento Valley, southern Cascades, and northern Sierra are forecast to remain dry at this point.

A longwave trough will then develop late next week over the Pacific Northwest, and bring a pattern change to the northern half of California by next weekend. There remains plenty of uncertainty as model solutions have been far from consistent. The past few runs of the GFS have trended from dry to minor precipitation amounts for the region; the ECMWF has been flip- flopping from dry to wet. This is still 8-9 days out, so plenty of time to iron out the details as the models will eventually converge.

Long story short: yes, there's a chance of rain. How much: TBD.

Rowe

AVIATION. VFR conditions are forecast to prevail over interior NorCal next 24 hours. Winds generally less than 12 kts.

STO WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
