RogueWaves Posted December 31, 2017 Share Posted December 31, 2017 Hit -17F about 1:30 am before clouds rolled in. Getting some light snow now even, so may add to my 24.1" total for the month which will be about 240% of avg! December doesn't get much better around here for combined cold-n-snow, tho this region has had at least four (2000, 2008, 2016, 2017) to balance a rash of total duds during the same period.

cyclone77 Posted December 31, 2017 Share Posted December 31, 2017 After a very slow start to December it finished quite nicely. Picked up 6.2" of snow during the last week. The weather station only picked up 0.11" of precip, but adding a guesstimated 0.35" to that brings us to around 0.46" for the month. That combined with only 1.13" in Nov made for a very dry final two months of the year. Will end the year with 34.93". Link to comment Share on other sites More sharing options...

Hoosier Posted December 31, 2017 Share Posted December 31, 2017 ORD is at 0.0 through the 30th, so today will push the temperature departure into negative territory. Pretty impressive to reverse a ~+4F anomaly in the final week. Link to comment Share on other sites More sharing options...

cyclone77 Posted December 31, 2017 Share Posted December 31, 2017 Nice explanation from DVN as to why temps were a tad "warmer" than expected this afternoon on the IL side. After a night of light snow, we only really has a few hours of clearing skies to cool off, and the result was an extremely cold start, but extremely shallow inversion to begin out day. The Davenport COOP observing site run at our office reached -15F this morning around 8 AM! The shallow nature of the arctic inversion did in fact still bring the milder than previously expected highs to the eastern half of the CWA today, as we have climbed to the lower single digits to around 8 in the east half. The west, were the inversion had more time to set up, and corresponding greater depth, has remained colder, and below zero thus far through 130 PM. Upstream, the 1050mb surface high (observed), was located in eastern Montana, and it`s ridge runs southeast to north central KS as of 18Z. Link to comment Share on other sites More sharing options...
michsnowfreak Posted December 31, 2017 Share Posted December 31, 2017 December finished with an impressive 23.3" of snow imby. It featured nearly all precipitation in the form of snow, but for a few hundredths of an inch of rain the first few days of the month, and most of the snow was powdery. Total precip was 1.63", of which 1.59" fell as snow. So while snowfall was nearly double normal, precip and temps finished below normal. My calendar year precip finished at 37.43" and my calendar year snowfall at 46.3". ************************************************************* For Detroit, the 22.5" of snow in December ties 1895 for the 5th snowiest December on record. Only 1974, 1929, 2000, and 1951 recorded more December snow. The calendar year officially saw 35.46" of precip, which was just over 2" above avg. And the calendar year snowfall of 43.0" was right near avg, technically a half inch above. I thought this was interesting. March, May, August, November, and December finished colder than normal. But due to several very warm months, including the 2nd warmest Feb & Apr, the year itself will finish 6th or 7th warmest on record. Link to comment Share on other sites More sharing options...
Chinook Posted December 31, 2017 Share Posted December 31, 2017 How long has it been since there has been a 1050mb pressure in the contiguous USA? (and not in West Yellowstone Montana, with huge SLP correction factors) Link to comment Share on other sites More sharing options...
Chambana Posted December 31, 2017 Share Posted December 31, 2017 Despite lots of sun, only managed a high of 2 degrees, windchills hovering around -10 to -15 all day. Picked up around 1/2” of fresh powder last night, freshened up the winter landscape a bit. Now the free fall begins. Low of -15 forecasted tonight. Everyone be safe tonight.

I know the high with the 2011 GHD storm was over 1050 mb, but there very well could have been one since then. 1060+ is when it really gets into rare territory.
