A deep, rich moisture pool is now over Mexico with much of it the result of now defunct TS Arleen. A .75 – 1.00 area of PWAT is expected to surge north through Mammoth by Mid week. As the Continental high forms over the four corner states, moisture and vorticity will be channeled up the Eastern Sierra early next week with the moisture surge peaking about Tuesday PM into Wednesday Night. Showers and Thunder A good Bet.  This will be the first Monsoon Surge this season.  High temps in Mammoth will peak Sunday. With the moisture advection expected early next week the high temps may be tempered a bit pulling back into the low 80s by Tuesday/Wednesday.
