November/December 2017: A Roller Coaster Ride
The last month of meteorological Fall and first month of meteorological winter proved to be interesting ones across the Midwest for sure. Here is an overview of what happened in chronological order. We start off with the beginning of November 2017.
Warm Weather Continues into November
The fall season for the Midwest has been a warm one so far, and October finished up to be well above normal for the region. The pattern that kept the first part of the season mild proved to have lasting strength into the home stretch. Along with remaining warm, the pattern was dry as well. Let’s review.
Another Warm Month for the Midwest
In the spirit of Halloween, October brought many more treats than tricks weather-wise. Outside of a cool finish to September, the warmer than average conditions continued into fall’s first full month. Was the warm weather also accompanied by an active pattern? Let’s review.
Wild Weather for the West Coast
The Pacific Northwest can be known for patterns of constant waves of potent mid latitude cyclones which can bring high winds and torrential rains. Thanks to a blocking pattern downstream, this region is in one of those patterns, with the first of a pair of powerful storm systems crashing ashore today. The second of the two powerful lows is set to follow this weekend, and it has an interesting story to tell.
Cool Weather Bookends a Warm September 2016
September began on a fairly cool note in the Midwest as the first three days of the month averaged anywhere from 2 - 6 degrees below normal (highs in the mid to upper 70s and lows in the 60s to even the upper 50s). The cooler spell would not last, however, as around a week of 80 degree plus days followed after the 4th. In fact, some of the hottest days of the month occurred in this span, with Rockford, IL reaching 92°F and Chicago, IL hitting 91°F both on the 6th.
A Wet and Active August for the Midwest
Severe weather was largely held in check during the months of June and July 2016 as a relatively quiet summer continued across the Midwest. August, on the other hand, told a different tale as an increase in the activity brewed across the region. Just how active did it get for the Corn Belt states? Let’s review.
A Cool Start to July, then Stormy
Back in June, summer heat finally arrived across the Midwest, however, the month ended with a few cooler days before flipping the calendar to July. Was this cool down signifying below normal temperatures once again in July or would summer temperatures prevail? Let’s review.
A Cold Start, but a Severe End to March
While February ended up warmer than normal, March had a much chillier, snowier start. Chicago was the first to partake in this return of winter. Right as we flipped the calendar, arctic air plunged southward, joining up with a storm system dropping out of the Pacific Northwest and sweeping through the Plains. This storm system produced anywhere from 1 inch of snow over Chicago Metro to Rockford, with up to 2 to 5 inches closer to the Wisconsin border.
