Tuesday AM: 6:20am

Subtropical moisture is surging northward from tropical storm Paine. Showers and higher humidity has moved into Southern Ca. High level moisture has made it as far north as Kern County with more of it moving north.   High clouds will be on the increase today for the central and southern sierra.  For today and Wednesday…there will be a slight chance of showers here in southern mono county.  Deeper moisture will remain well to our south. Winds will slowly ramp up over the next few days with a cooling trend.

However, expect another warm day today (low 70s) followed by increasing wind and cooling Wednesday and Wednesday night…..Moisture trajectories again favoring a more eastward trek.   However, because of how dynamic the Wednesday storms is…..a few inches of snowfall looks likely Wednesday Night into Thursday….

The first day of Fall Thursday looks quite chilly with highs in the 40s…. lows in the 20s Friday AM




How wonderful is a wind shift!  Just look outside….it’s clear this morning at least in the Mammoth Area. Light westerly flow developed late yesterday afternoon and flushed out the smoke from the Owens River fire. Light westerly flow will give way to strong westerly flow by Wednesday as a Trof from the GOF drives a vigorous cold front through the high country Thursday Morning….


In the last updated Dweeb Report, it was indicted that the remnant moisture from Hurricane Paine, now due west of Cabo San Lucas would stay to our south and east. This morning the situation is more concerning as the latest model runs have the moisture moving much further north into the interior Central CA and it may coincide with the vigorous trof digging south from the GOF, Wednesday night into Thursday.

The Screaming message here is that if you are going into the back country over the next few days, you need to be prepared for the possibility of winter conditions Wednesday Night and Thursday above 8000 to 9000 feet.  The combination of subtropical moisture and a very dynamic cold trof can drop a lot of snowfall in a short period of time…..  Daytime highs in Mammoth on Thursday will be in the 40s! with 20s Thursday night into Friday AM…..


The weekend looks fair and warmer…..70s
