Seasonal temperatures are expected the next two days as short wave ridging build over the area.  Another late season trough descends from the GOA Friday bringing gusty winds and cooler temps Friday through Saturday.  Winds may reach advisory level Friday afternoon and night.  Temperatures will cool some 10 to 15 degrees between Thursday and Saturday. However, this cool down is not as strong as last weekends.  Lows at night are not expected to reach freezing over the weekend at resort levels but may get close to that in some remote areas along the highway 395 corridor Sunday AM.

Looking at the climate signals, there is a slow moving Kelvin Wave entering the western pacific. This is thought to be causing a false MJO signal by its air sea coupled convection over the western pacific.    Week two models sill show a slight weakness in heights at 500 mb over the far west during that period, meaning that temperatures will average closer to normal at resort levels as opposed to the coastal sections where it may get toasty next week.  Normal highs for Bishop are upper 80s now and for Mammoth and June Lake, upper 60s.  Seasonal temps are expected today.

 

Expect windy weather to develop Friday and especially Friday night as a short wave Trof moves through the area. Highs will cool to the low 60s on Saturday and this system is accompanied buy some initially-dry air. So Fire weather concerns are highlighted Friday and Friday night.  The is a 20% chance of showers Saturday over Mono County. expect rapidly warming temps Sunday into Tuesday next week.  Longer range guidance is still flirting with the idea that next weeks Trof  may be the last of Spring.  The ECMWF has hot subtropical ridge over us by the 25th of June while the GFS has a digging trof coming out of BC, Can.   So…. too soon to say Spring is over.
