D'oh! If you don't like the weather now, just wait a few minutes

We're in store for another of those classic mood swings by Mother Nature where the weather goes from warm to cold and back to warm.

Today's unseasonable warmth will lead to a chance for severe thunderstorms tonight, followed by a chance of accumulating snow Saturday, and then warm weather again late next week.

Here is what the National Weather Service says about tonight's storm in their Hazardous Weather Outlook:

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TONIGHT. THE PRIMARY HAZARDS WILL BE DAMAGING WINDS AND LARGE HAIL. AN ISOLATED TORNADO CANNOT BE RULED OUT.

A LINE OF STRONG TO LOCALLY SEVERE THUNDERSTORMS IS EXPECTED TO DEVELOP OVER MISSOURI THIS EVENING...THEN MOVE EAST ACROSS THE OUTLOOK AREA TONIGHT. THE LINE IS EXPECTED TO CROSS MOST OF SOUTHEAST MISSOURI AND SOUTHERN ILLINOIS BETWEEN 9 PM AND 2 AM. THE GREATEST POTENTIAL OF SEVERE STORMS WILL BE DURING THIS TIME PERIOD.  

Even more fun comes this weekend thanks to Winter Storm "Homer":

A PERIOD OF SNOW IS LIKELY SATURDAY AS A SWIFT MOVING...UPPER LEVEL STORM SYSTEM MOVES QUICKLY SOUTHEAST ACROSS THE MID MISSISSIPPI VALLEY. A SWATH OF ONE TO THREE INCH ACCUMULATIONS COULD OCCUR SOMEWHERE ACROSS THE QUAD STATE. IT IS TOO EARLY TO DETERMINE WHERE THE HEAVIEST SNOWS WILL OCCUR. TEMPERATURES WILL BE COLD ENOUGH TO ALLOW FOR ACCUMULATIONS...ESPECIALLY ON GRASSY AREAS.

This is the same kind of Alberta Clipper system that was forecast to drop snow last Saturday, but delivered squat. I'm too lazy to generate a new Dartboard Forecast for Homer, so just refer back to the forecast for Winter Storm Grampa, which is roughly the same.
