BOOM, BOOM, OUT GO THE LIGHTS...
Friday was just a splendid day of weather for those of us living in the central Midwest. Highs from north to south were in the range of 55-60 degrees. Temperatures near St. Louis were around 75 with a few spots just south of there reaching 80 degrees! That's what I call bonus weather.
This caps off a spectacular two week run of weather where highs in Cedar Rapids and the Quad Cities have averaged 50 degrees per day.
The core of the warmth has been focused on the central Plains where highs have averaged 10-15 degrees above the norms over that same period.
This is a trend that goes back to June. Below you can see how much of the nation has experienced above normal readings the start of August.

ALL GOOD THINGS MUST END...
As the saying goes, all good things must come to an end and the painful process of transition gets underway tomorrow and is fully inflicted Monday when a powerful cold front will snap the flag poles delivering much colder air. Below you can see Saturday's noontime temperatures area a good 10-20 degrees colder across the board. That will keep highs in the range of 40-45 degrees. Still not bad but noticeable.
The knock out punch comes Sunday when a clipper cuts across Minnesota delivering an old fashioned haymaker. Ahead of the system, highs will rebound a bit from Saturday reaching 45-55 degrees on brisk south winds. Enough moisture will make into the area ahead of the front and its forcing for clouds and some widely scattered showers, especially near and east of the Mississippi where the moisture is a bit more robust. As you can see, the EURO is more aggressive than the GFS in terms of rainfall.
The EURO
The GFS
As for the cold front, it's a doozy and come noon Monday readings are in the low to mid 20s except in the far south. The cold air aloft will create enough instability for scattered snow showers or flurries.
Making the cold far more significant will be a tight pressure gradient that could send wind gusts over 40 mph. The generates wind chills of 5 to 15 degrees. It will not be a pleasant day!
This graphic from the NWS in the Quad Cities shows the wind potential Sunday night and Monday
SO WHAT ABOUT SNOW?
With a deep layer of cold air in place the next system appears to have the makings of a light over-running snow event Tuesday. Modeling has been quite inconsistent in the strength and placement of any snow. The GFS and Canadian GEM have been especially erratic. It appears that they are struggling to achieve saturation due to very dry air. They have little if any snow as a result. The EURO though has shown the least deviation the past 3 days and I feel it may have a better handle on the dynamics. As such I am leaning its way for now but with lower confidence than I would like to see. Here's what the latest models are showing for potential accumulations. 3 significantly different solutions.
The EURO
The GFS
The Canadian GEM
I guess we'll see where things stand tomorrow as we are still a good 3 days away.
Another far more dynamic system is due into the region towards the end of next week. The GFS and GEM put us in the warm sector and make it a rain producer. The EURO has consistently maintained colder temperatures and delivers a snow event. No sense in splitting hairs over this set-up which is a week out. For what it's worth the EURO indicates this for snow out of that system.
Way down the road, there is still plenty of potential for cold air in January, something I continue to follow. In his second addition on cold January's in Iowa, Steve Gottschalk (celebrating 60 years of weather observations) has compiled this interesting list of chilling January's followed by some of his always interesting observations & folklore.

Some Weather Forecasting Clues
If you watch the jet contrails they can give you clues to the upcoming weather. If they disappear quickly that means that the air is dry in the upper atmosphere and that the weather will remain dry. If they are numerous and linger with them spreading out that means the atmosphere is moistening up and there will be a change in the weather be it a wind shift, a change in the temperature and possibly some precipitation.
If you have a heavy frost in the morning there is a very good chance that the day will stay dry, especially if the wind is in the northwest, north or the west.
Last but not least, I was looking up other years that are similar to where we are now with 7 of the past 11 days having 50 degree temps. and found 6 of them. 4 of those years had a normal to colder than normal winter yet. Even during an La Nina
