$$What forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Sacramento, CA wrote its last area forecast discussion before this river flood warning went out at Dec 15, 3:28 PM PST, 10 hours 55 minutes earlier.
Area forecast discussion, Dec 15, 3:28 PM PST, 10 hours 55 minutes before
Area Forecast Discussion National Weather Service Sacramento CA 328 PM PST Thu Dec 15 2016 .SYNOPSIS... Wet and windy weather with high-elevation snow into tonight. Showers ending over the Sierra on Friday. Freezing temperatures in the valley this weekend with dry conditions. Mainly dry next week except for a chance of light showers during mid week. && .Discussion... The main 4+ anomaly TPW plume has moved inland ahead of the vort max near 30N/130W with widespread precip across the CWA, save for the extreme Nrn Shasta Co mtns (Zone 13). Radar loop showed heavy rain from Lake Co into Butte Co and then into Wrn Plumas. Smaller bands of heavier rain noted across Sierra, Nevada, Placer counties with rain rates up to .80 per 3 hrs. The heavier bands of rain should sag SEwd through the evening hrs over the CWA as the short wave trof off the Nrn CA coast moves inland overnite. This short wave energy seems to have invigorated the front just N of SAC. As an example, at 2230z-2320z, the one hour accumulation showed a heavy rain band up to .50" per hour and small pixels of .80-1.0" from SMF-BAB and this will sag SEwd into the SAC and probably Nrn SJV area this evening. This has prompted the issuance of a FLS for all or portions of the Srn Sac/Nrn SJV/Delta. The short wave off the Nrn CA coast will shunt the main plume and main rain band Swd into and south of the 80/50 corridor through the evening/overnite hrs. Snow level profilers indicate the snow level ranging from 7000 ft over Shasta Co to 8000-9000 ft over the Sierra and these levels won't lower over the Sierra until after midnite. Precip will rapidly coming to an end on Fri and it appears we can contemplate ending the winter storm warnings late tonight or early Fri morning, about 12 hrs or so earlier for zone 69. Some showers and much lower snow levels expected mainly over the west slope Sierra on Fri as secondary energy rotates through the upper trof during the day. Radar indicates the back edge of the main area of rain has basically sagged south of the far Nrn Shasta Co mtns and rates have let up. By late afternoon a band of post frontal showers has developed in the EKA area and will cross the Coastal Range this evening. QPFS in this area should be lower tonite than early in the day as the main band of rain has shifted Swd. Surface pressure gradient MFR-SAC has weakened to 5 mbs and the winds that occurred overnite and early this morning over the Nrn portion of the CWA have weakened. Will continue the Wind advsry for the Srn portion of the CWA due to the front sagging SWd over that portion of the CWA this evening, along with the 925 mbs wind core of 50 kts also sagging Swd over the Srn portion of the CWA this evening. Winds/Rain rates should peak this evening in the SAC area around 02z-04z time frame, and possibly until 06z in the Nrn SJV. Weather clears out Friday night as upper ridging develops over the eastern Pacific and northerly winds develop. Clear skies and cold airmass will allow overnight lows throughout the central valley to drop to near or below freezing. Coldest nite appears to be Sat nite into Sun morning where they will be several hrs of temps =<28f for "Hard Freeze" conditions especially in the Nrn/Central Sac Vly. High surface moisture may allow for some fog to form as well especially southern Sacramento and northern San Joaquin valleys where winds should be a little lighter due to decoupling. Sunny skies Saturday will allow for a little warming some areas but cold airmass will keep highs below normal. Sunny skies and continued breezy north winds are expected on Sunday with a little warming but daytime highs are still expected to remain below normal. JHM && .EXTENDED DISCUSSION (Monday THROUGH Thursday) An upper level ridge of high pressure will bring dry conditions to northern California Monday and through the day Tuesday. The next weather making system will be approaching the region Tuesday night as a upper level shortwave trough slides across the Pacific northwest. This system will bring rain to the valley and snow to elevations higher than 4000 to 5000 feet Tuesday night through Wednesday. Model differences are still present for the timing and progression of the system next week, but models in general agree to having a stormy pattern return for the forecast area. Temperatures will remain slightly below normal. && .AVIATION... Low ceilings and reduced visibilities will continue as a storm system passes over Norcal the next 12 to 18 hours. Occasional wind gusts up to 20 kts possible in the valley with gusts up to 45 kts for the mountains. Conditions will improve for valley terminals late Friday morning to early Friday afternoon. && .STO WATCHES/WARNINGS/ADVISORIES... Flood Watch through late tonight for Burney Basin / Eastern Shasta County-Central Sacramento Valley-Clear Lake/Southern Lake County-Motherlode-Mountains Southwestern Shasta County to Northern Lake County-Northeast Foothills/Sacramento Valley- Northern Sacramento Valley-Northern San Joaquin Valley-Shasta Lake Area / Northern Shasta County-Southern Sacramento Valley- West Slope Northern Sierra Nevada-Western Plumas County/Lassen Park. Winter Storm Warning until midnight PST tonight for Western Plumas County/Lassen Park. Winter Storm Warning until 4 am PST Friday for West Slope Northern Sierra Nevada. Wind Advisory until 10 PM PST this evening for Carquinez Strait and Delta-Motherlode-Northern San Joaquin Valley-Southern Sacramento Valley. &&
