Partly cloudy skies continued most of the day Tuesday as the remains of the closed low that moved through CA Monday and Tuesday…slowly moved east over Arizona last night. That system is progged to move into Western New Mexico, then drop south to NW Mexico by Thursday and over the Sea of Cortez by Saturday. By Sunday and Monday it will be off the coast of Baja over the Eastern Pacific. Meanwhile, a strong moist belt of westerlies will bring a lot of rain to Washington State and BC today and through the weekend. Some of this rain over the next few days will be from a tropical storm now east of Hawaii. So an AR event for the Canadian Coastline and Washington State is expected.

Central and Southern CA will have a strong warm up between today and Friday. High pressure aloft will nose into Central CA with 500mb heights about 594DM. This will make for highs in Mammoth near 80 and Bishop temps climb to near 90 by Friday, and stays there through Tuesday.

Concerning the upper low that circles back into Southern CA next week, that system may bring some showers by Tuesday or Wednesday next week for So-Cal. High temps will pull back a bit next week as the upper high this weekend breaks down Sunday. However, low to mid 70s are still likely through Wednesday here, a full week away.

Longer range:

According to todays inter-seasonal forecast for the CFS V2

The weather will be come much cooler the week “beginning” the 19th of October with at least some light precipitation for Central Ca that week. The last week of October is when a big change is indicated for our area with the first substantial snow storm arriving that week. No date specified yet. Again, the Storm or Storm’s are likely to be cold with snowfall as the temperature anomaly shows well below normal temps. The Dweebs will update on this change, “next week” to see if some fine tuning can be done….”either way”. 😉
