FREEZE WARNING TONIGHT

A cold ridge of Canadian high pressure remains to the west of the Stateline stretching from central Canada southward along the Minnesota/North Dakota border across northwestern Iowa to southwestern Missouri. This ridge continues to be the dominate weather maker for the mid west. The northwest air flow is cold with low humidity levels. Skies will clear after sunset, and temperatures will plummet. So, a FREEZE WARNING has been issued again tonight with overnight lows expected to be in the upper 20's. It will be mostly sunny and cool on Wednesday with a high in the low 50's.  With the ridge slowly nudging it's way eastward, the winds will not be as strong... though still north to northwest at 6 to 12 mph.  On Wednesday night the high will pass over the Stateline, skies will be clear, winds will be light, and it will be cold again with areas of frost developing after midnight as temperatures drop into the upper 20's toward daybreak.  With the ridge to the east of the area on Thursday, winds will become light southerly.  Skies will start off sunny in the morning, but become partly cloudy in the afternoon.  A system over the Rockies will edge into Nebraska by early Friday morning with a warm front stretching to the southeast across Kansas into southeast Arkansas.  The southerly air flow from the Gulf of Mexico will bring increasing moisture northward  into the mid west.  Skies will become mostly cloudy on Friday, and there will be a good chance of showers, and possibly even an isolated thunderstorm to the Stateline before the day is over.   Showers and thunderstorms will be likely on Friday night and Saturday as the warm front moves into Illinois, and then northward across the area on Saturday.  Skies will be mostly cloudy, and it will be warmer with a high  near 70 degrees.  It will be mild with more showers and thunderstorms  on Saturday night.  The mostly cloudy skies will continue on Sunday.  With a front lying just to the northwest of the area it will still be warm on Sunday with a chance of more showers and thunderstorms.
