SYNOPSIS. Deep monsoon moisture moving into the region will bring scattered showers and isolated thunderstorms to the district through Monday, especially over the higher elevations of the Sierra. Wednesday through next Friday will be predominantly dry except for the slight chance of thunderstorms over the high Sierra each afternoon.
DISCUSSION. A few showers over Inyo County moving towards the Indian Wells Valley this morning. Otherwise a mix of mid level clouds due to an influx of monsoon moisture. Water vapor images show a disturbance over Arizona with lots mid to upper level moisture moving towards south California. The upstream sounding from Las Vegas indicates lots of mid level moisture and instability with precipitable water of 1.4 inch. Think a few showers will be possible today towards the Kern County Mountains and desert. The GEFS and EPS ensembles are in fair agreement through next 5 days. Models prog for a trough over AZ to move west towards S CA as an inverted trough with plenty of monsoon moisture ahead. This will be the feature for the increase threat of showers and isolated thunderstorms across the area. Higher resolution models show convective potential mainly over the sierra today with an increasing potential towards the Mojave Desert starting late tonight. Progs show an increase of monsoon moisture with precipitable water values of 200 percent above normal over the sierra today and 250 percent above across the Kern County Mountains and Desert Monday afternoon. While the inverted trough will be just off the SCal coast. This may place the south half of the district in a favorable mid level forcing to initiate convection Monday. Locally heavy rain will be possible with the stronger storms today over the sierra and towards the Kern County and Sequoia areas Monday afternoon. The 24 hour probabilities of 0.25+ inch for Monday in China Lake is 22 percent and around 42 percent in Sequoia area of Tulare County. Models in fair agreement the trough will remain offshore while a ridge builds over the interior west. Southerly flow aloft maintains the axis of higher monsoon moisture along and east of the sierra for much of next week. Thus a daily chance of showers and thunderstorms in the Sierra for much of next week. Temperatures over the next seven days will be near or above climatology.
AVIATION. Isolated afternoon thunderstorms over the sierra. Otherwise VFR conditions can be expected over much of the central California interior during the next 24 hours.
AIR QUALITY ISSUES. On Sunday July 25 2021 . Unhealthy for sensitive groups in Sequoia National Park and Forest. Further information is available at Valleyair.org
