The storm that moved into northern California during the evening of April 24th brought thunderstorms to the northern part of the state. This was an indicator of the highly unstable airmass accompanying the storm. Thunderstorms developed over central California around midday and had strengthened to near severe levels by the middle of the afternoon. Three Severe Thunderstorm Warnings were issued by WFO Hanford on the 25th, two of which were for a particularly long-lasting storm. Eleven Significant Weather Advisories were issued for non-severe thunderstorms due to the threats of hail and strong outflow winds. Hail estimated at al least a half inch in diameter was reported from these storms, as were wind damage and at least two funnel clouds. The thunderstorms brought appreciable rains to Fresno, giving the city its fourth wettest April 25th on record (0.55 inch; wettest is 0.93 inch in 1952). Bakersfield had a storm total of 0.36 inch. This brought its monthly total to 0.50 inch, just under the average rainfall for April of 0.52 inch. The rainfall from this storm ensured that neither Bakersfield nor Fresno would have its driest rain season on record, although conditions for the season remained much below normal.
A very cold airmass moved into central California behind the cold front. By late on April 25th, snow was being reported down to the 3800-foot elevation, and storm-total snow estimates were as high as 25 inches in the high country of the Southern Sierra Nevada, and up to 3.5 inches in the Tehachapi Mountains. High temperatures in the central and southern San Joaquin Valley on the 26th were only in the 60s, compared to the mid 80s only a week earlier.
Very strong winds developed during the afternoon of April 25th in eastern Kern County.  Particularly strong gusts of wind struck a semi truck trailer around 3 PM in the afternoon and caused it to flip.  There were then two additional flipped tractor trailers.  The CHP closed US 395 as a result of the dangerous cross winds for high profile vehicles.  Winds were estimated at 60-70 mph at the time of the event.
An upper-level ridge built along the coast during the last days of April. Temperatures warmed to near normal by April 28th, and continued warming through the end of the month. The last day of the month saw high temperatures in the central and southern San Joaquin Valley reach the low to mid 90s, or 10-15 degrees above normal.
April 2014 tied for the fifth warmest April on record for Fresno. For Bakersfield, April tied for the 14th warmest April on record; one of the Aprils it tied with was from last year.
