Nice Warm up on Sunday!

Canadian high pressure still dominates Stateline weather tonight, but it is beginning to shift off to the east .  A light southerly wind has developed, but with mostly clear skies early tonight, and fresh snow cover,  good radiational cooling is taking place, and some spots have already dropped into the single digits as of 9:55 pm.  The overnight low in the Rockford area shound be around 10 above with slowly rising temperatures late as a south to southeast wind picks up to 10 to 15 mph  before daybreak.  Winds will already be brisk by 8 am on Sunday gusteing 20 to 30 mph by 8 am.  The strong winds will last through the early to mid afternoon.  High temperatures will rise into the low 40's melting some of the snow the recently fell.  It appears as if all of the precipitation with this system will fall across northern Minnesota, extreme northern Minnesota, and the upper peninsula of Michigan.  A dry cold front will pass across northern Illinois during the Sunday evening supper hour.   High pressure will take control of area weather on Monday.  It will be sunny and colder with a high in the middle 30's.  High pressure will shift off to the east early Tuesday allowing a significant weather system over the plains to shift eastward toward the Stateline. Gulf of Mexico moisture will move in with the next system.  Skies will quickly cloud over on Tuesday morning and there could be some rain or snow.  With warmer temperatures during the afternoon precipitation will change over to rain.  It will be breezy, and there could even be some thuderstorms on Tuesday night.  The low will occlude out over Iowa on Wednesday and begin to weaken as it moves slowly across the midwest on Wednesday and Wednesday night allowing rain and snow showers to continue off and on ending as snow showers on Wednesday night as colder air follows in behind the departing low pressure system.  Weak high pressure will ridge into northern Illinois on Thursday, and skies will become mostly sunny with high temps in the upper 30's.  Yet another low pressure system has the area in it's sights late in the week, but it is far to early to estimate expected weather conditions for next Friday.
