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 San Diego, CA wrote its last area forecast discussion before the first event at May 19, 8:29 AM PST, 2 hours 11 minutes earlier.
Area Forecast Discussion National Weather Service San Diego CA 929 AM PDT Fri May 19 2017 .SYNOPSIS... High pressure building across CA and weak offshore flow will create widespread above normal high temperatures through Saturday. Above normal highs will continue for inland areas through early next week, with gradual cooling the latter half of next week. A return of a shallow marine layer and weak onshore flow will create the possibility of low clouds and fog along the immediate coast Sunday morning, spreading slowly inland next week. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... At 9 am PDT, water vapor satellite imagery displayed an upper- level ridge off of the California coast. Visible satellite showed a few low clouds over the coastal waters, with clear skies elsewhere. Surface observations showed east to northeast wind gusts of mostly 20-30 mph through mountain passes and along coastal mountain slopes, due to a 1022 mb high over northwest Utah and a 1012 mb low just south of San Diego. A warming trend will continue across the region this weekend as heights aloft increase and offshore flow keeps the marine layer shallow and offshore. H850 temperatures will increase to around 25 deg C by Monday, which will help highs in the Low Deserts increase to the low 100s F Sunday through Tuesday. Mountain and Valley areas will be warmest Saturday and Sunday, while Coastal areas will begin to see relief Sunday as the marine layer slowly redevelops. Only one site is forecast to break a record high on Saturday and Sunday at this time. Chula Vista's old record for Saturday is 79 degrees set back in 1941 and they are forecast to hit 83. Sunday's record high for Chula Vista is 76 set in 2012, and they are forecast to reach 79. Weakening surface pressure gradients will create onshore westerly winds across the region by Sunday afternoon. Offshore winds today through Saturday are expected to remain below Wind Advisory criteria. Patchy fog and low clouds could return to the coast Sunday morning, has greater chances Monday morning, and should push into the valleys by Tuesday morning. Lowering heights and the return of onshore flow and marine layer will help highs across the region return to seasonal normals by Wednesday, with slightly below normal highs expected on Thursday and Friday as upper-level troughing develops along southwest California. && .AVIATION... 191525Z...P6SM and primarily SKC expected through Saturday morning. One possible exception is the very slight chance of fog within 3 sm of the coast 20/0600-1500 UTC. && .MARINE... No hazardous marine weather is expected through Tuesday. && .SKYWARN... Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. && .SGX WATCHES/WARNINGS/ADVISORIES... CA...None. PZ...None. && PUBLIC...JJT AVIATION/MARINE...Harrison
