Local Long range weather thoughts and El Nino influences

The storm track tells the story of the influences of El NINO. Take a look at this jet streak model from the UofM atmospheric Center: (streak is correct, it is not technically a continuous stream) http://www.atmos.washington.edu/~ovens/loops/wxloop.cgi?h250_wind+/-168// You will notice that the jet streak splits with the main streak heading south to California, then accross the southern US, and then up the eastern seaboard. During the run you will notice the big void running North South up the coast - that is the big blocking ridge that has been the culprit of this cold dry pattern. This is typical El Nino influences. Hope - Towards the end of the model series you will see it inch up toward Org/Wa border. If this hold true, it will draw up warmer air from the SW. Because warm air typically holds more moisture it is likely for this to be be our next best chance to get snow. ...JDM
