A strong high pressure ridge over the region produced hot temperatures across interior Northern California from May 14th to May 17th, with many new daily high temperature records set. Record daily high minimum temperatures were also set as clouds and northerly winds maintained the heat overnight. The hot temperatures lingered into the 19th, especially for the northern San Joaquin Valley (see Episode for May 18th and 19th).
