Friday marks the 271st day without measurable snow; 3rd longest snow drought on record here

 

Another record is being challenged—one which covers the number of days without measurable snow here. Friday marks the 271st such day. It last snowed here measurably back on March 4 when 0.3″ accumulated.

 

If the current streak without measurable snow extends another 9 days, that will tie the Chicago area’s longest period free of measurable snow which was recorded in November 1994; a tenth day would establish a new record

 

What makes the outcome of our march toward this record a bit dicey is the fact a clear majority of computer model forecast runs the past three days—14 of the most recent 16 forecast cycles—indicate sticking snow is possible in  the 1 to 2 week range. Clearly, this may impact whether we establish a new record.

Lake Michigan drops to its lowest November-level ever, tying the record; It’s 16 inches below year-ago levels and 29″ behind November’s long-term average 

 

The U.S. Army Corps of Engineers, which has measured and recorded Great Lakes water levels since 1918, reports Lake Michigan has tied its record for the lowest November lake level. It’s running 16 inches lower than a year ago and 29 inches off the long term November average.

 

And there’s still one more for the record-books here —this one covering Chicago sunshine

 

Never, since sunshine measurements began in 1893, have 14 consecutive months produced above normal sunshine. Never—that is—until this year. November 2012 will go down in the books as the latest sunnier than normal month.

 

Unseasonably mild early December open ahead; first 3-day string of 60+ degree early December temps in 30 years on the way

 

High temperatures at or above 60-degrees are predicted Saturday, Sunday and Monday—December 1,2 and 3—in Chicago. The last time a December opened with three consecutive 60-degree readings was 30 years ago in 1982.

 

Such a string of warm December days has occurred only twice over the city’s 142 year observational record.

 

An influx of Gulf moisture is to turn the mild air mass drizzly and foggy Saturday night into Sunday morning with some patchy light rain possible—suggesting the warm spell isn’t unlikely to be gloriously sunny.

 

Waves of drenching rain, high winds and waves and a mountain of high altitude snow pounding the West

 

The same storm hammering the West with high winds and waves, drenching rainfall and mountains of high elevation snow, is responsible for the eastward surge of mild Pacific air across the country which is to produce an unseasonably mild December open in coming days. Above normal temperatures are predicted —literally from coast to coast—over the weekend. Temperatures may end up as  much as 24-degrees above normal in the Plains.
