St. Patrick's day turned out to be a winner temperature-wise for all of northern Illinois. Rockford reached 67 degrees at 2:59 pm and stayed there past 5 pm. That reading was the warmest temperature reported at the airport since November 22nd, 2010 when the high was 69 degrees. Also...the first city in northern Illinois this season to reach 70 degrees was Savannah. It will not be as warm tomorrow. A cold front has pushed though Rockford this evening, and it will continue it's southward move ovenight. High pressure will begin to take charge of area weather on Friday as it nudges into the upper midwest bringing cooler temperatures on a northerly wind running about 10 mph. It will be cooler, but not drastically so, with an afternoon high in the low 50's which is still above average for this time of year. Skies will clear on Friday night and temperatures will drop into the upper 20's. Saturday will turn out to be a great day with sunshine, blue skies, light northeast winds with a comfortable afternoon high in the low 50's. A developing warm front will set up across the middle Mississippi Valley by late Sunday, and approach the Stateline early on Monday morning. That will set the stage for showers and thunderstorms on Sunday and Sunday night as an incrreasing flow of warm moist Gulf air rides up and over cool air in place over northern Illinois. Another disturbance will follow on the heels of the first, and keep precipitation going off and on through Tuesday night, when colder air will follow in behind the second departing low pressure system mixing some wet snow in with the rain, and that mixture may last through early Wednesday. The rest of the week will be chilly with high temperatures in the mid to upper 30's.
