Episode narrativeepisode_narrativeOn the 28th, southeast winds aloft began to bring mid-level moisture from northern Mexico and the Desert Southwest. For the first time in approximately three weeks, isolated thunderstorms developed over the Sierra crest around Kings Canyon and points just to the north and east. The surge of monsoonal moisture continued through the end of the month, with the strongest thunderstorm activity on July 30th and the morning of the 31st. A few thunderstorms over the Southern Sierra Nevada had rain rates of an inch or more in an hour, and a severe thunderstorm moved over Edwards Air Force Base during the afternoon of the 30th. The warm nature of the monsoonal moisture kept central and southern San Joaquin Valley high temperatures around 100 degrees through July 30th. ||A line of thunderstorms moved through the central and southern San Joaquin Valley during the morning of July 31st, bringing record-tying rain to both Bakersfield and Fresno. After the thunderstorms moved out of the San Joaquin Valley, skies began to clear and temperatures warmed rapidly. With the cloud cover, the temperature at Fresno was between 70-72 degrees for most of the morning of the 31st. But once the clouds began to clear, the temperature warmed at a rate of 8 degrees per hour from 11 AM to 1 PM (reaching 88 degrees), and topped out at 97 degrees at 5 PM.|Both Bakersfield and Fresno were 0.6 degrees warmer than normal for July. However, July was the last month to use the 1971-2000 30-year climatological normals. The new normals, for 1981-2010, were implemented of August 1st.
