What a day! Mid January in Mammoth and temps like early spring!

The high today was 56 at the Village at Mammoth breaking the old record of 53 set back in 1994. As of 2:40 pm the high in Bishop was 75 so far today with higher temps still possible. The old record was smashed by 4 degrees set back in 1958. Another warm day for January is in the cards for Tuesday.

The eastern pacific ridge is set up along the west coast and so record highs are occurring over Southern Ca as well.  A mild off shore flow is coupled with unusually high heights for this time of the year.

An inside slider will intensify the off shore flow Wednesday night for LA. So more of a strong Santana will result.

Over the next few days the eastern pacific ridge will retrograde westward allowing for some Great Basin cooling to move in from the North Wednesday into Thursday. Night time lows will return to the single digits and teens during Mid week.

Over all, we are in a typical positive phase PNA pattern that is common during Mid January. This pattern is highlighted by strong temperature inversions…warmer then normal temps over all with little in the way of precipitation. This pattern often times can last 21 days.  Dry weather is expected through the next Weekend.,


The inter-seasonal phenomena convective portion has moved into the Western Pacific…and although a strengthing upper jet is in process….it has not progressed into the Eastern Pacific.  Its location in phase 6 often times is associated with above normal precip in Central California. It is still progressing eastward. Phases 7 and 8 are even more favorable for increased storminess for Central and Northern California.

CPC is not encouraged as there has been thus far, no indication from the numerical guidance (GFS or ECMWF) (Week 2) of a pattern change to wet for California.  The Dweebs comment….There is still plenty of time. Will keep weary eye on the subject!

More later……..The Dweeber!
