Episode narrativeepisode_narrativeBehind this final trough, cold air settled into the San Joaquin Valley. An upper-level ridge built into the state, bringing mostly clear skies and light winds. Radiational cooling resulted in late season frosts over the region during the early morning of February 16th.||An upper-level trough moved through the central California interior on February 18th. This trough brought spotty light showers to the region, and wind gusts to around 40 mph in the Kern County desert. The main impact on the central and southern San Joaquin Valley was another surge of cold air behind the cold front. High temperatures on February 19th were several degrees cooler than the previous day.||A trailing short-wave dropped through California on February 20th. This disturbance triggered a couple of afternoon showers near the Southern Sierra Nevada crest, but otherwise had no impact on the central California interior. Temperatures in most locations around the region were a few degrees warmer as the cold air began to moderate.||An upper-level ridge built toward the California coast on the 22nd, and remained near the state the next several days. Temperatures warmed to above normal on February 22nd, and a few degrees warmer on the 23rd before leveling off the next day as the ridge remained just offshore.||The upper-level ridge moved onshore on February 24th ahead of an approaching upper-level trough. This brought strong warming to the central and southern San Joaquin Valley, with both Bakersfield (81) and Fresno (77) breaking their record high temperatures for the date by one degree. For Fresno, this broke a record that had stood for 116 years, since 1896. For Bakersfield, this was only the second time this year that the high was in the 80s. The other time was January 2nd, when the high was 82 degrees.
