What forecasters said that day
The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Hanford, CA wrote its last area forecast discussion before this wind advisory went out at Aug 19, 12:24 PM PDT, 5 hours 25 minutes earlier.
Area forecast discussion, Aug 19, 12:24 PM PDT, 5 hours 25 minutes before
Area Forecast Discussion National Weather Service Hanford CA 1224 PM PDT Sat Aug 19 2023 .SYNOPSIS... Strong thunderstorms across Central California are possible today associated with moisture ahead of Hurricane Hillary. More widespread precipitation is forecast for tomorrow, especially in Tulare and Kern County -- including the Mojave Desert -- where catastrophic flash flooding is conceivable. Rainfall associated with Hilary will mostly exit the region by late Monday. A few residual showers and thunderstorms in the Sierra Nevada are forecast through the end of the work week. && .DISCUSSION... All eyes are currently on Major Hurricane Hilary, which is still south of the forecast area, but impacts begin today. Moisture associated with TC Hilary coupled with hot surface temperatures will provide enough instability to support strong thunderstorms. A severe thunderstorm or two today cannot be ruled out, with the main hazard being strong downdraft winds. We have been included in a rare "Marginal" Risk by the Storm Prediction Center for just about the entire forecast area. The risk for severe weather will decrease when the sun goes down later this evening. However, the flood thread will continue to increase through the night. Additionally, breezy conditions through the Grapevine and Highway 58 at the south end of the valley today may lead to some blowing dust. Once the isolated thunderstorm risk wanes tonight, the broader rain shield will move over the area. This precipitation shield will grow in coverage through the night and morning hours tomorrow. There is a risk for heavy rain bands associated with Hilary that have catastrophic flash flooding potential due to the unusually potent moisture source that is associated with Hilary in the Mojave Desert. The Weather Prediction Center has put the desert area of Kern County in a very, very rare "High Risk" for excessive rainfall on Sunday. The high desert in Kern County will be really under the gun in terms of flash flooding potential later tomorrow morning through the evening hours as abundant moisture associated with Hilary pushes inland. Flooding potential extends both north and west of the desert tomorrow... flooding in locations such as Bakersfield and Kernville cannot be ruled out, as well as foothill and mountain locations in Tulare County. The main circulation associated with Hilary will exit the region later on Monday, which is when the heaviest rainfall and our Flood Watch are set to expire. Once things are all said and done, the wettest locations in the Mojave Desert in Kern County may see 4-5 inches of rain through Monday. Residual moisture will linger over the High Sierra through the rest of the week. This will lead to thunderstorm potential through the end of next week, but will be isolated in nature compared to the showers and storms associated with Hilary. && .AVIATION... Areas of MVFR and local mountain obscuring IFR conditions in and near showers and thunderstorms in the Sierra Nevada and adjacent foothills after Saturday 19z. Showers and thunderstorms will also impact the Kern County desert with areas of MVFR after Saturday 19Z. Otherwise, VFR conditions will prevail through at least the next 24 hours. && .AIR QUALITY ISSUES... ISSUED: 08/18/2023 14:47 EXPIRES: 08/19/2023 23:59 None. && .CERTAINTY... The level of certainty for days 1 and 2 is medium. The level of certainty for days 3 through 7 is medium. Certainty levels include low...medium...and high. Please visit www.weather.gov/hnx/certainty.html for additional information and/or to provide feedback. && .HNX WATCHES/WARNINGS/ADVISORIES... Flood Watch through Monday evening for CAZ314-316-322-328>339. && ab weather.gov/hanford
