What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS San Francisco Bay Area, CA wrote its last area forecast discussion before this gale warning went out at Oct 13, 5:21 PM PDT, 3 hours 52 minutes earlier.
Area forecast discussion, Oct 13, 5:21 PM PDT, 3 hours 52 minutes before
Area Forecast Discussion National Weather Service San Francisco Bay Area 521 PM PDT Tue Oct 13 2020 .SYNOPSIS...Warming and drying trend will continue through Friday as high pressure builds back across the region. Offshore winds will also develop, becoming locally strong and gusty in the North and East Bay, especially in the hills, from early on Wednesday through Friday morning. Strongest winds are forecast from Wednesday evening through Thursday morning. These winds will occur in conjunction with a very dry air mass, resulting in critical fire weather conditions. && .DISCUSSION...As of 02:00 PM PDT Tuesday...Water vapor imagery shows high pressure starting to build over California today, with sunny as well as dry and warmer conditions prevailing across the Central Coast this afternoon. Temperatures are running up to 4 degrees warmer than this time yesterday, with Santa Rosa upward of 7 degrees warmer. This additional warming is likely due to some light offshore winds there, aiding in the adiabatic warming. These north to northeast winds will continue to develop across the region tonight, becoming locally gusty in the hills by morning. This ridge will continue to build along the West Coast this week, and will be dominant weather feature through at least Friday, with even warmer and drier conditions developing as well as stronger offshore winds. Looking specifically at the temperatures for the time being, temperatures will warm a few degrees each day, with 850 mb temperatures warm to near 23 degrees C by Thursday. This means that with no marine layer to speak of that most areas will be 12 to 20 degrees warmer than normal for this time of year. Will need to take a closer look at record temperatures for Thursday and Friday, but we may have a few locations flirting with those kinds of numbers. If that is the case, will likely need to consider issuing a heat advisory, but for now, the heat risk is only indicating a moderate risk for those that are sensitive to the heat. The other main story this week will be with the developing offshore winds over the next few days, and the critical fire weather conditions.. The 12z NAM and WRF show the strongest offshore gradient Wednesday night into Thursday morning, with KSFO to KWMC upwards of -16.5 mb by 12z Thursday. That gradient combined with 925 mb winds in the 30 to 40 kt range across North and East Bay, felt confident in upgrading the Fire Weather Watch to a Red Flag Warning as extremely dry air will accompany these winds. Daytime humidity values will likely fall into the single digits and teens, with overnight RH values struggling to recover into the teens and 20 percent range. While the strongest winds will likely be focused on the North and East Bay Mountains and Hills, with gusts up to 55 mph possible over the highest ridges and favored peaks, cannot rule out some gusty conditions in the Santa Cruz Mountains as well. These winds will likely gust up to 45 mph in the windiest locations. Also expanded the Red Flag Warning to include the North and East Bay Valleys. Confidence is there that these areas will see the extremely low humidity values, but the winds are the question. Given that it does not take much winds with those kind of humidity values, and believe gusts up to 30 mph are not out of the question, have included the North and East Bay valleys as well. This ridge will shift farther to the west this weekend, allowing cooler conditions to finally return. At this time, still believe inland areas will be quite warm on Saturday, but most areas return to normal ranges by Sunday. These cooler and more seasonal conditions will prevail through the first part of next week. Unfortunately, it looks to remain dry through the period. Palmer && .AVIATION...As of 5:20 PM PDT Tuesday...For 00Z TAFs. VFR with clear skies throughout the region. These conditions will continue throughout the TAF period, with NNE winds aloft keeping the dry airmass in place. As noted in previous discussion, LLWS will be a factor at several terminals overnight (KSTS/KLVK/KAPC/KSJC) into tomorrow morning with light winds at the surface and 20kt-30kt northerly winds at 1000ft-2000ft AGL. This event is expected to last through Friday morning, so additional LLWS in subsequent TAF packages possible. Winds at the surface are moderate onshore with breezier conditions through coastal gaps. Winds will subside overnight. Vicinity of KSFO...VFR through the TAF period. WNW winds at 18 kt continuing through early evening and subsiding overnight. Surface onshore flow continuing tomorrow. SFO Bridge Approach...Similar to KSFO. Monterey Bay Terminals... VFR. Light to moderate winds, easing overnight with VFR conditions. Models hint at a little cloud cover build up along the coast from the northwest winds over the ocean, but no impacts are expected at terminals. Pattern continues through tomorrow. && .FIRE WEATHER...As of 02:15 PM PDT Tuesday...Primary period of concern is from Wednesday morning through Friday morning when models develop locally strong and gusty north to northeast winds in the hills, especially the North Bay Mountains and East Bay Hills, but also at the higher elevations of the Santa Cruz Mountains. Latest NAM starts to ramp up northerly winds in the hills early Wednesday morning, especially over Napa County, but also farther south into the Diablo Range. Significantly stronger and gustier winds are then expected to develop and become more widespread in the hills Wednesday evening and peak overnight Wednesday night into early Thursday morning, then diminish during the day on Thursday. An uptick in wind speeds is likely again on Thursday night, but winds then are not expected to be as strong as those Wednesday night. In addition to gusty offshore winds, an extremely dry air mass is forecast to move in from the north and northeast. Afternoon relative humidity values beginning Wednesday are forecast to drop into the single digits and teens, with very poor overnight recoveries anticipated. Based on these expected developments, critical fire weather conditions will likely occur at elevations above 1000 feet in the North Bay Mountains, East Bay Hills, and Santa Cruz Mountains between Wednesday Morning and Friday Morning. The Fire Weather Watch has been upgraded to a Red Flag Warning for the North Bay Mountains, East Bay Hills and Santa Cruz Mountains from early Wednesday morning to Friday morning. A Red Flag Warning was also issued for the North and East Bay Valleys, as extremely dry conditions will develop there, with some locally gusty winds possible as well. Winds are forecast to subside in all areas by Friday afternoon and temperatures are forecast to cool next weekend. && .MARINE...as of 02:37 PM PDT Wednesday...Winds remain out of the northwest being moderate to gusty across the waters through midweek. These winds generate steep fresh swell resulting in hazardous seas conditions for small crafts. By late Wednesday, the winds are forecast to strengthen more to gale force gusts of 35 to 45 kt over the northern outer waters. A moderate northwest swell will peak through tonight and a longer period southerly swell arrives Wednesday evening. && .MTR WATCHES/WARNINGS/ADVISORIES... .Tngt...Red Flag Warning...SCA...Pt Arena to Pigeon Pt 10-60 nm SCA...Pt Arena to Pt Reyes 0-10 nm SCA...Pt Pinos to Pt Piedras Blancas 0-10 nm SCA...Pigeon Pt to Pt Piedras Blancas 10-60 nm && PUBLIC FORECAST: Palmer AVIATION: Lorber MARINE: DK FIRE WEATHER: Palmer/Blier Visit us at www.weather.gov/sanfrancisco Follow us on Facebook, Twitter, and YouTube at: www.facebook.com/nwsbayarea www.twitter.com/nwsbayarea www.youtube.com/nwsbayarea
