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

 
     SUMMARY FOR THE NEXT 6 DAYS-- UPDATED FOR Sunday, March 21st at 7:30am---

Relatively  normal start to the week with temperatures slightly below normal over the fresh snow cover in IA,WI and above to near  normal temperatures elsewhere. Snow will not last long, as temperatures in the 50's to 60's will once again return to the South with 50's common elsewhere for Mon and Tuesday. By mid-day Tuesday a weak system will brush mainly the far North with mainly rain. Next chance and maybe last chance of a accumulating snowfall looks in the cards for just outside of the short range for the 27-28 of March. Temperatures until then from Tuesday onward look near to slightly below normal in the North and above normal in the South and East.  see long range for the potential early arrival of spring.

MN/WISC  North- North of 45 degrees  latitude. South- South of 45 degrees latitude.

Dec-Feb deviation from normal in the North--+1F.  South -1.  SE WI has the highest chance of above normal snowfall. Other areas should be near normal (40" in the South to near 100" in the Arrowhead of MN.) % of normal snowfall-- SE WIS 100-120%  all other areas- 85-100%. 

 IA-  temp -2   snow- % of normal snowfall 90-110%

Mich  temp -3 snow-% of normal snowfall  105-125%  (125% in the extreme south and east)

Long Range-  potential for accumulating snow fall over the North for the 27-28. Temperatures look to be below normal, especially in the North and East. This time period will likely have the last decent skiing of the season for the resorts that are still operating as the pattern looks to shift to full blown spring by Easter,, and may do so a tad earlier. This spring pattern looks to continue will into April as April at this time looks above normal for most of the region.

     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.
