Temperatures are due to plummet in Wisconsin this weekend. The all important question in our weekend weather is of course the game day forecast at Lambeau Field, where the Packers and Giants meet for the NFC title game Sunday. Weather Central meteorologist Brian Olson says fans had better dress warmly, with wind chill factors around ten degrees below zero. Olson doesn't expect temperatures to return to the 20 degree range until at least next weekend. That's going to seem like shorts weather! Olson says our frigid forecast is buckling of the jet stream: cold air that's been bottled up in Canada is pouring into Wisconsin.
