Warmer Weather to Start November

After a wet and warm start to October, unseasonably cold air moved in to Central Illinois for the final week. The Heart of Illinois saw it's first freeze of the season on Sunday, October 29th as temperatures fell in to the mid to upper 20s for the first time since March. 

With the start of a new month temperatures are warming back up. Through the the first week of November temperatures are expected to gradually warm. While a series of cold fronts will help keep temperatures from warming much above average, temperatures are expected to reach the upper 60s by Sunday, November 5th

Even though temperatures are expected to gradually warm, a series of cold fronts will bring multiple chances of rain to Central Illinois. Each disturbance that passes will be fairly mundane at least until Sunday, November 5th when a strong cold front could bring the threat of severe weather back to Central Illinois.

The month of November is often referred to as "The Second Season" of severe weather for the state of Illinois. It's not unusual to see a few outbreaks of severe weather during the month as we transition from the warm and humid months of summer to the cold and dry months of winter. 

November Climate Outlook 

The Climate Prediction Center is currently projecting a wetter than normal with an equal chance (33.3%) of seeing above, cooler, or near average temperatures.  

While medium to long range models show temperatures climbing well above average during the first week of November, they are only going to be there briefly. A series of cold front will try to keep these temperatures in check while reinforcing cooler temperatures across the region.

Throughout the month, temperatures will gradually become colder as fall begins to transition to winter. However, overall confidence in how cold these temperatures could be after the first two weeks of the month is low. 

 A weak La Niña climate pattern is well on the way to forming in the eastern Pacific, which could lead to some pretty volatile weather throughout the month, so above aveage precipitation seems reasonable. Typically, La Niña climate patterns produce colder and snowier winter seasons across Central Illinois. That may very well be the cae for the 2017-2018 winter season.
