Winter Storm: Dec. 1-2 -- Update #2

Winter Storm Watches have been issued from the CO/KS borders through eastern NE and covering portions of MO/IA/SD/MN/WI and IL. Areas under the watch can expect severe winter conditions to become possible within the next 48 hours, potential for heavy snows, freezing rain accumulations along with other types of winter precip. This is a very difficult forecasting situation, with such a strong gradient between receiving heavy snows and substantial amounts of freezing rain. To read the latest Winter Storm Watch texts, please head to this Link; You will have to search for your nearest NWS office and read their watch for your area.

Current forecasts seem to have pushed the all snow line further to the north than my forecast last night, indicating that only areas of SD/MN may receive all snow. All areas of Iowa seem likely to receive more than one precip type from this event. Northern Iowa mainly snow, but some freezing rain/sleet possible, the central and southern two-thirds of the state are all currently included in 'moderate risk' of seeing a quarter of an inch or greater amounts of freezing rain. This is a large concern and could very well become reality. Another complete forecast update will once again come later tonight.
