5/5/2015 8:00 AM 0.00 0.0 0.00 M M For the past week a weak but broad trof has been present over California. While no direct precipitation threat was felt on the S.J.Valley Floor, the instability aloft combined with surface heating has been supporting widespread convection over the adjacent Southern Sierra Nevada in the afternoon and early evening hours. The flow aloft has been weakly from the east so thunderstorm cirrus anvils have brought early evening cirrus before dissipation overnight.

5/8/2015 8:00 AM 0.05 0.0 0.00 M M Instability showers associated with an Upper Low Aloft, its cool air, and surface heating brought precipitation around Central California the afternoon of Thursday May 7th. While the obs site did NOT have substantial rain, there were areas, particularly SW of Chowchilla that did receive larger amounts of rain with ponding of water on relatively flat farm ground.
