-- Final  WINTER OUTLOOK posted in Long Range-----  11/21

 
     SUMMARY FOR THE NEXT 6 DAYS-- UPDATED FOR Tuesday, March 16th at 12:01am---

                       BIG SNOW POTENTIAL FOR IOWA INTO WISCONSIN for WK-END!!!!!!!                       

Mild air will continue over the region for most of the work-week resulting in significant snow loss at resorts that still have a snow cover in the North and East. Temperatures will remain above freezing for most areas at night resulting in not being able to make snow at most locations. Hope lies at the end of the work week with a very dynamic system taking shape in the Pacific Northwest and then rapidly gaining strength as it moves to lee side of the Rockies in New Mexico or Southern Colorado. Cold air will quite be  extensive with this system for mid-March , in fact so much so, it will not allow the storm to produce accumulating snowfall much further north than Minneapolis and on to the NE. Further South and to the East will likely be a near perfect situation for heavy snow. At this time the heaviest axis of snow looks to be setting up shop from somewhere in Southern,IA (will go with Des Moines for now) and extending NE to near the Madison, WI area. Amounts at this time appear to be 6-8"+ in the this area with potential for 10'+ in localized areas. Storm is still over 4.5 days away, so a lot can change,, but the models so far are scary in how consistent they are with each other. Stay tuned.  Temps appear to remain below normal for the wk-end for all but the East.-- see long range for more chances of snow.

Long range forecast / discussion...March 22 to 28

Long Range-

one more blast of winter looks likely for the last 8-10 days of March and into very early April with much below normal temperatures and chances of accumulating snow from 2 different weather systems.  (mainly the North and East). Temperatures may once again flirt with single digits in the north and low to mid-teens in other areas,, which will seem quite cold after the much above experienced with the recent surge of warmth. Don't put those ski's away quite yet. However, after about April 5th-- spring looks to arrive in full force likely cutting short many ski areas planned closing of mid April.

                              Final Winter Outlook 2009/2010   11/21

     Yes, the rumor is true. An El Nino is currently underway in the central and eastern Pacific Ocean. This will impact the upper midwest's weather this winter, and many outlets are predicting a warmer than avg winter and less precip based on El Nino for the upper Midwest. However, several points need to be made;

1: This Nino is currently weaker than it was forecasted to be now several months ago. If it continues to weaken, this will affect the weather in the upper midwest,, more so than most forecasters let on. In fact,  those who want a colder than normal winter in this situation actually want the El nino to increase before decreasing in the late winter  UPDATE**** 11/21 . The EL Nino is finally getting it's act together  and is currently the strongest it has been all year long. Expect this trend to continue with the weakening phase starting sometime in late Dec early Jan.

2: El Nino is just one player on the field amongst other "tools" long range forecasters use. These other factors are likely going to subdue the effects of El Nino this winter, especially if El Nino starts to weaken in mid-late winter.

3: not all El Nino's are the same, especially this one.  This is a reactionary Nino to last years' La nina. This El Nino is not the  driving force like they sometimes can be in the atmosphere.

4: sunspot activity is at a low point. In fact, it's starting to get a tad scary. Lack of sunspots means the sun is emitting  about .1 of 1% less energy. It makes a difference, especially coupled with all the other "tools".

Based on other measured teleconnections across the world along with the idea of this El Nino weakening in the dead winter is starting to make the forecast for the Upper Midwest more clear for the winter months. The fact that  the El Nino has increased in intensity actually gives credence to a prediction  of it fading as mentioned above when factoring in the other teleconnections around the world.
