Still No Measureable Snowfall...

A trace of snow was all that was recorded at the Rockford airport.  So, still no measurable snow for the season in Rockford.  The Rockford area may break the longest snow less period since records began in the early 1900's without at least 0.1", if there isn't at least a tenth of an inch on Monday, because no snow is expected for the rest of the week... but there is some potential with snow showers a possibility during the mid day hours. When snow showers occur is snows fairly heavily for a short period of time, and then stops almost as abruptly as they start.  Once in a while a series of snow showers will end up dropping measurable amounts of snow.

A strong cold front is moving across the Stateline tonight. Patchy drizzle will come to an end, but scattered flurries will develop overnight as the colder air moves in from the northern plains. The low will be around 30 tonight with westerly winds at 10 to 15 mph. Cold Canadian air will feed across the upper mid west all day on Monday, so the temperature will not rise much. The high will be in the low 30's with a northwest breeze at 10 to 20 mph. Scattered flurries may occur from time to time with a chance that some heavier snow showers may develop during the mid day hours.   With Canadian high pressure in charge, skies will become partly cloudy on Monday night, and the temperature will drop to a chilly 18 degrees.  The temperature will actually be seasonable on Tuesday with a high around 34 degrees under partly cloudy skies as the cold high starts shifting off to the east.  The upper air pattern will be in the process of shifting again as we head into midweek.  The air flow will become more westerly and even west/southwesterly.  That will allow milder air from the Pacific to begin to flood eastward across the nation again.  The warm up will be gradual.  It will be mostly sunny of Wednesday with an overnight low around 20 degrees, and an afternoon high up around 39 degrees.  By Thursday morning the old Canadian high will be locked in place over the southeastern states.  The southwesterly flow around the back side of he old high will pump in warmer temperatures from the plains states.  It will be a beautiful sunny day with a nice southwesterly breeze, and a pleasant afternoon high of 43 degrees.  That is notable because the average high for December the 13th is 34 degrees.  On Friday clouds will increase as a slow moving front settles in toward northern Illinois.  High temperatures will still be in the low 40's, and there could be some showers at night.  A fairly significant storm system is expected to develop into the mid west by Saturday.  It does have the potential of producing some good rainfall amounts... possibly up to 1".  It will be in the form of rain, too, because it will be too warm for any snow.  Sunday will be partly cloudy and a little cooler with highs in the upper 30's.  So, no Canadian air will be tapped behind the Saturday system.
