This is the official winter broadcast for the winter of 2010-2011 from The Weather Centre's weather headquarters. All stated items in this broadcast are meant to be strictly informational and are not under copyright of this blog. This statement is likely to be revised on average once every 2 weeks or so.

SECTION I: Precipitation
La Nina has come into effect, which started in June. This La Nina has been proved to exist by various charts, maps, and a temperature detecting loop model imagery. El Nino typically provides below-average precipitation across the Midwest region, as a El Nino was in effect last winter, providing less snowfall than expected. This winter, however, is expected to be above normal precipitation, as La Nina is opposite in effects to El Nino. Thus, the Midwest region should be recieveing above average snow/precipitation.

SECTION II: Temperature
This summer has been above normal for temperatures in the region this blog covers. A local meteorologist disclosed that hotter summers - as hot as the current one - have 4 out of 5 times, lead to colder winters than normal in the local region. Thus, I am forecasting colder temperatures.

SECTION III: Types of precipitation
Snow: Snow is forecast to occur more often with cooler temperatures and above normal precipitation this winter.
Rain: Rain chances are down compared to last year and other years as colder temperatures are forecast.
Ice: Ice is forecast to decrease slightly as temperatures are colder, but is boosted as more precipitation is forecast.

The 2010-2011 winter in this region is forecast to be LESS RAINY, MORE SNOWY, and NOT MUCH CHANGE for ICE.

La Nina Update

La Nina is forecast to last until possibly early 2011
