What happened

The episode as NWS HNX wrote it up.

An unstable airmass over the Central and Souther San Joaquin Valley produced strong thunderstorms during the afternoon of the 22nd, and persisted into the early evening hours. At least two funnel clouds were observed over southern Madera County. A thunderstorm that developed southwest of Hanford (Kings County) intensified rapidly as it moved east, becoming severe as it reached the Kings/Tulare County line. A spotter reported hail in excess of -inch in diameter from the storm.

What forecasters said that day

COLDER AIR. MODELS SHOW THE DEEP MOISTURE WILL MOVE EAST OF THE
AREA THIS EVENING WITH THE PASSAGE OF THE UPPER TROUGH. HOWEVER
WILL CONTINUE WITH CURRENT WARNINGS WITH MUCH COLDER AIR LOWERING
SNOW LEVELS TO FOOTHILLS. THIS WILL RESULT IN SNOW ACCUMULATIONS
OF SEVERAL INCHES ALONG THE SIERRA FOOTHILLS. SNOW MAY DROP DOWN
TO 1500 FEET TONIGHT BRINGING THE ACCUMULATING SNOW THREAT TO THE
