Prairiedog Posted January 31, 2014 Report Share Posted January 31, 2014 Interesting article on the historical droughts in California. There were some crazy long droughts that lasted decades. Now with so much agricultural dependance on California, IF history were to repeat itself with a much longer drought, I'm seeing tomatoes at $10/lb and forget our winter fruit. Economic results would be terrible. Shaping up to be the driest 2012-13 in over 400 years! Could help Oregon wine producers as Cali would have trouble keeping up with the demand. Now back to the cold. http://www.mercurynews.com/science/ci_24993601/california-drought-past-dry-periods-have-lasted-more Quote Link to comment Share on other sites More sharing options...
Deweydog Posted January 31, 2014 Report Share Posted January 31, 2014 Well the 12z models all agree on the undercutting theme from the last few days. Euro at 192-216 would be a nice and quick snow dump. That's my point. I think there's a better than decent change we'll see things trend away from a quick transition. 1993 is a pretty decent analog, though. Kind of the same rudderless pattern leading up to the initial event, although it was a far more traditional block. This one is just goofy. Quote My preferences can beat up your preferences’ dad.

Kind of the same rudderless pattern leading up to the initial event, although it was a far more traditional block. This one is just goofy. Because the models agree on it right now? I don't know, sometimes you have to kind of take the models at face value. 1993 was a pretty rare and prolonged blocking pattern. People forget that we had a 2nd big arctic airmass crash into the eastern side of the region a few days after the 2/19 event. Given the rather quick hitting tendencies of February blocks, I don't think that's in the cards this time around. Quote Link to comment Share on other sites More sharing options...

No, because of the consistent tendency this winter, and the last few for that matter, has been to diminish the strength and impact of Pacific influence as things draw near.

Phil Posted January 31, 2014 Report Share Posted January 31, 2014 Well, for the first time this winter, the stratosphere is beginning to favor you guys. This is good news given the stratosphere has been dominating the macro-scale boundary conditions all winter. We have had absolutely zero ENSO/AAM inertia this winter..and a very weak, submissive MJO/RMM due to the incredibly anomalous QBO stress fields. The result of the said hemispheric shear regime has been persistent NPAC height rises. While the tropical forcings have been able to knock the ridging/wave breaking around, the general theme of rising heights somewhere around the NPAC continued given the momentum above the ferrel cell rifts.Huge changes going on in the stratosphere right now, I counted 7 different breaking eddys on last night's 00z RAOB analysis. This time favoring the PNW and western Cadada. The PV is going to bifurcate, and coupled PVA's will disperse and dampen. Convection will soon erupt over the IO/WPAC as CDS support is lessened..expect that Hadley Cell to begin pumping, as the Walker Cell type flow becomes jostled.

Snowman Josh Posted January 31, 2014 Report Share Posted January 31, 2014 Definitely looks good Wed/Thur timeframe(18z) for a system to slide down from the BC coast. Could be sooner if the approaching wave becomes more consolidated in the northern branch. Definitely cold enough air in place with -8 to -12 850's widespread. Looks 50/50 at this point. I'm still holding out hope for some snow showers early Sunday as the semi-arctic boundary makes its way through the central Puget sound. Quote God, I'd give anything for a drink.
