Quick Update Friday:

Latest guidance shows a weak upper jet at 250MB over the northern Ca along with a VT max/ upper wave moving north off shore.  Monsoon moisture and air mass modification will continue through Saturday afternoon with Precipitable water increasing to over an inch here in the Mammoth Area by Saturday. Odds of measurable precipitation will increase to 40% for showers and thunderstorms today. Saturday is somewhat of a question as there is so much moisture that if we do not get much daytime heating there would less chance of thunderstorms and a greater chance of just showers. We call this condition (over-developed). Nevertheless, showers are still expected through Saturday night and there is always the possibility of a few of them to be locally heavy.

Daytime highs will average 75 to 80 and night time lows 45 to 55 Friday.  Saturdays highs will be cooler with the anticipation of more cloud cover, so low to mid 70s.  Again….Some showers have the potential to bring locally heavy rain later today Friday and into this evening. And again Saturday through Saturday evening. Storms are expected to push off to the east Sunday afternoon with increased SW flow aloft. There is a 20% chance of showers Sunday…..mainly before the afternoon.

The outlook calls for dry weather most of next week with the return of zephyr winds. Daytime highs will be mostly in the mid to upper 70s next week.

 

Next update Monday..
