The clouds broke just enough for temperatures to reach the low 80's in Rockford, upper 70's in many other spots. But this will more than likely be the last 80 degree day of 2015 as cooler fall air is on the way.
Is it possible that temperatures will warm back into the 70's? It is, but climate tells us that our days are numbered as the average high drops from the upper 60's in the beginning of October to the middle 50's by the end.
The reason for this is because each cold front that passes during the fall and early winter months, brings colder and colder air with it. Certain global atmospheric conditions may limit just how much cold air follows each cold front,
but the general trend is for temperatures to cool. With the shorter days and lower sun angle in the sky, we're not able to maximize our heating, causing temperatures during the fall and winter to cool - reaching climatologically the coldest three month period of December, January and February. Once the earth begins to tilt back towards the sun, our days turn longer and warm up.
Now this doesn't mean all gloom and doom as we have some very nice fall days to look forward too. Let's just hope we're able to enjoy them before diving right into winter.
