Looks like a repeat of yesterday, except more moisture today and an earlier start to rain expected. The intensity of the rainfall will be determained by the amount of sunshine we have. At the moment, its pretty cloudy but there are some breaks. Mammoth picked up .24 inches of rain last evening and night. There was thunder as well.

As per KHNX discussion this AM at 9:00am:

“UPPER LOW IS NOW CENTERED ALONG THE BORDER BETWEEN KERN AND TULARE COUNTIES NEAR 35N/118W. A FAIRLY STRONG VORT MAX AHEAD OF THE LOW HAS PUSHED INTO SOUTHERN NV AND HAS TAKEN MOST OF THE SIGNIFICANT CONVECTIVE ACTIVITY ALONG WITH IT. SOME MID LEVEL MOISTURE IS BEING PULLED BACK FROM THIS FEATURE AND WRAPPED AROUND INTO CENTRAL CA WHICH HAS PROVIDED AREAS NORTH OF KERN COUNTY WITH SCATTERED LIGHT SHOWERS THIS MORNING”.

Only interesting addition is the *MUCAPE:  J/kg

Only about 750 J/kg at 9:00am over head;  However, just a short distance to the west it is as high as 3000 J/kg and just to the east across the NV/CA border 2000 J/KG probably associated with the VT center near the NV/Ca *

Also Retired….WSFO forecaster Doug Armstrong pointed out this AM that there may be some snow over the highest elevations below some of those rain shafts.  (Freezing level is above 12K)

MUCAPE (Most Unstable Convective Available Potential Energy) is a measure of instability in the troposphere. This value represents the total amount of potential energy available to the most unstable parcel of air found within the lowest 300-mb of the atmosphere while being lifted to its level of free convection (LFC). No parcel entrainment is considered. The CAPE and CIN calculations use the virtual temperature correction.

The LPL (Lifted Parcel Level) allows for the determination of the height of the most unstable parcel. This makes it easy to identify areas where the largest CAPE is “elevated.”
