The local office's own words before the first event, 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 the first event at May 31, 2:42 PM PST, 9 hours 18 minutes earlier.
Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 342 PM PDT Wed May 31 2017 .SYNOPSIS... A low pressure system will continue to move east away from the region tonight. High pressure will build in behind the system, bringing dry and warming conditions through the end of the week. A brief slight cooldown will then be in store for early next week, as a another frontal system brushes our area. && .DISCUSSION... An upper level trough continues to move through the region this afternoon. Shortwave energy dropping south has dug the trough farther south than models had been forecasting and measureable precip was recorded at many central California locations. The increased clouds and precip combined with the cooler air brought in by the frontal system are producing afternoon temperatures around 15 to 20 degrees lower than yesterday, well below seasonal normals for the end of May. Precip will linger over the mountains of Tulare and Kern Counties this evening, with a few sprinkles possible in the desert zones as well. A dry and warming trend will begin on Thursday as the upper low continues to sink southeastward toward northern Mexico and high pressure builds inland across California. This ridge will amplify through the weekend ahead of another developing low pressure system in the northeast Pacific. This will push temperatures back to around 10 degrees above climo by Saturday. There are some model differences with the evolution and trajectory of the northeast Pacific low, but most solutions keep our area dry as the trough stays mainly to our north. There will be another slight cooldown for the first part of the week with the passing trough, bringing afternoon highs to around normal by Monday. && .AVIATION... Local mountain obscurations over the Sierra Nevada and Tehachapi Mountains until 17Z Thursday. Otherwise, VFR conditions are expected across the central CA interior during the next 24 hours. && .AIR QUALITY ISSUES... None. && .CERTAINTY... The level of certainty for days 1 and 2 is high. The level of certainty for days 3 through 7 is medium. Certainty levels include low...medium...and high.
