Ever heard of a pneumonia front?

I remember when I was a kid my mom would say "it's pneumonia weather out there."  She was so far ahead of the National Weather Service.

...PNEUMONIA FRONT MOVING DOWN WESTERN LAKE MICHIGAN...

A PNEUMONIA FRONT CURRENTLY IN FAR SOUTHEAST WISCONSIN WILL CONTINUE TO RAPIDLY DROP SOUTHWARD INTO NORTHERN ILLINOIS AND INDIANA TONIGHT. THIS FRONT HAS BEEN MARKED BY A DRASTIC CHANGE IN TEMPERATURES AND A STRONG WIND SHIFT. TEMPERATURES ALONG THE LAKE FRONT HAVE DROPPED FROM THE LOW TO MID 70S TO THE MID TO UPPER 40S AS THE FRONT PASSES. WINDS HAVE SHIFTED FROM BEING LIGHT AND OUT OF THE WEST TO OUT OF THE NORTHEAST AND GUSTING UP TO 40 MPH AT TIMES ALONG THE LAKE. THIS FRONT WILL BE INTO LAKE AND MCHENRY COUNTIES BY 10PM...COOK... DUPAGE..KANE...DEKALB...AND BOONE COUNTIES BY 1045PM...AND THE REST OF NORTHWEST INDIANA AND NORTH CENTRAL ILLINOIS BY MIDNIGHT CDT.
