Little Change in the pattern through Tuesday….Then long awaited southward shift in the upper jet begins about mid-week…..

Not much to add to last Tuesday’s discussion other then to remove any chances of showers today Saturday. The Sunday/Monday short wave has a bit stronger upper jet, and has a bit more moisture. However, is still targeting Northern Ca the most with the possibility of some snow showers or light snow over the upper elevations. The Dweebs would not expect much more then 1 to 3 inches over Mammoth Mt beginning sometime Sunday pm through Monday AM. If, and that is a big if that system drops about 50 to 100 miles further south…that would make a significant difference in the amount of precip. Snow levels will be pretty high….7500 to 8000 feet
Significant changes well advertised earlier in the past week (see previous discussion from March 8th) begin to occur as upper ridging develops near the dateline causing the long wave trof to deepen along the west coast about midweek. The 12z GFS has the first system effecting the Mammoth area as early as Wednesday. However, that may be a bit fast. Will update on the timing as soon as the models come into better agreement.
The screaming message here is that winter will be making a return….just in time for Spring!
