September 9, 2019 - The National Weather Service Hanford Office reports high temperatures Monday afternoon will be six to eight degrees below normal for this time of year.
Maximum temperatures Tuesday afternoon will be around ten degrees below their typical values for the first half of September.
Area Forecast Discussion National Weather Service Hanford CA 335 AM PDT Mon Sep 9 2019 .SYNOPSIS... Below normal temperatures will continue through Wednesday then a warming trend will occur for the end of the week. Localy gusty winds will continue in the Kern County Mountains and Desert through Tuesday with breezy conditions elsewhere. Dry weather will continue with mostly clear skies through the upcoming week. && .DISCUSSION... Sunny skies with below normal temperatures prevailed over the Central California Interior as winds diminished over a majority of the region. Support at the surface has weaken as surface pressure gradients from KSFO-KLAS relax and the Fort Ord Profiler shows a less defined marine layer. Yet, support aloft (synoptically) will continue a upper air analysis shows a weak trof pushing through Northern California during the day this Monday. Therefore, will maintain a forecast of high temperature about 10 degrees below their seasonal average values as many locations see highs in the mid 80s. In addition, due to the location of the passing trof, surface pressure gradients will remain below the criteria needed for another round of strong winds (wind advisory products). Therefore, light breezes expected during the next 24 hours period and will therefore cancel the wind advisory for Kern County this morning. Heading into the middle of the week, models continue to show the series of trof passages as a deeper trof digs into California on Tuesday. Model confidence therefore continue to grow on the solution of having a few disturbances cross the state ahead of a ridge pattern later in the week. While the first disturbance may only keep conditions steady, the second disturbance may allow for an additional push of marine air into the region along with stronger winds. Model surface analysis has the pressure gradient from KSFO to KLAS returning to values near 10mb on Tuesday. If the values is able to reach above 10mb, then will consider the issuance of another wind advisory for the Kern County area. Reaching toward the longer term, models attempt to introduce zonal flow pattern ahead of yet another trof passage next weekend. The zonal flow pattern is indicative of a steady state conditions with little rise in temperatures expected. Therefore, once the temperature begin to rise on Thursday, no addition rises will occur later on Friday or Saturday. By Sunday, the next trof begins to enter the region with the trof axis over California on Monday. While too far out to consider precipitation with any confidence, longer range model solutions do attempt to bring precip into Northern California. Will watch the next Monday period for model evolution as that period reached toward the short-term.Source: NWS
