Monday AM Update:
Thermal Trof is currently over Nevada and so expect west wind to come up early today. New 12z Nam/WRF has 700mb moisture less then 70% for Mono County and the combination of the lowest thickness and track of the low ejecting to the NE will confine precip to Northern Ca. Additionally, the combination of early west wind….Surface convergence over Nevada and weak closed upper low moving in to the north of us will keep any TSRWs well north of Mono County Today. The next short wave is a bit stronger, however it too will be to the north of us. (DRY) I do see a stronger gradient for more afternoon wind Thursday/Ngt and possible wind advisories for Kern County Deserts north possibly to Southern Inyo county. Friday Am has 1000-500mb thickness for some short duration freezing temps Friday AM.
From Last Night:
No significant changes to our pattern. There are a couple of weak systems that will bring some afternoon clouds but no thunder is expected over Southern Mono County. A very small scale upper low will move through north central Ca Monday. In that Mammoth is to the south of that system, expect a bit more afternoon breeze and a few degrees of cooling.
The next upstream system looks to move through as an open wave now unlike the close low scenario expected a few days ago. This will provide a little stronger Zephyr wind Thursday into Friday with again a little cooling. High Temps over-all expected to remain between 65 and 72 degrees the whole week with night time lows from the mid 40s to the upper 30s….. The run off will continue……
Taking a peak at the longer range…..
Weeks 1, 2, 3 and 4 look normal as far as the precipitation anomalies. However, May is usually a fairly dry month anyway as compared to March/April. Temps are expected to be Normal to slightly above normal. Then…..There is an increasing bias for warmer then normal temps the first week of June. Can it be that we are really done……?
Latest from CFS calls for weak El Nino Conditions this Summer then ENSO neutral conditions returning by the Fall.
