Sunny Sunday

That large cold area of Canadian high pressure has slipped off to the south and east of the Stateline. It is still close enough that skies will be clear overnight, but it will not be as cold as last night when the temperature dropped to 10 degrees.  That 10 degree low was the coldest temperature recorded at the Rockford Airport since February 11th, when it dropped to 2 degrees.  Tonight, with southerly winds the low will be in the upper teens.  On Sunday it will be sunny, breezy, and warmer with a high temperature in the upper 30's.  The wind will be south to southwest between 10 and 20 mph, with some afternoon gusts to 25 mph.  The southwesterly winds will continue on Sunday night, and temperatures will continue to moderate.  It will still be mostly clear on Sunday night with a low around 27 degrees.  Moisture from the Gulf will reach the Stateline on Monday.  The skies will cloud over holding temperatures in the upper 30's for highs, and there could be some patchy drizzle or light rain showers in the afternoon.  The drizzle may last through the night Monday night, and with temperatures dropping to freezing or just below, there could be some freezing drizzle .  So, look out for the possibility of slippery roads and sidewalks on Monday night.  On Tuesday it will continue to be mostly cloudy, and with a weak front sliding though the Stateline, temperatures will be in the 30's, and there could be some light rain or light snow showers.  No significant precipitation is expected on Tuesday.  On Wednesday a warm front will be located across central Illinois.  It will be cloudy and warmer with a high in the low 40's.  With moisture over-running the front there will be a good chance of showers.  The warm front will approach the Wisconsin-Illinois stateline on Wednesday night.  Rain will be likely, and there could be some significant rainfall totals.  Estimates at this time range from .50" to around 1.50". A cold front will sweep across the area by daybreak on Thursday.  High temperatures on Thursday, in the low 40's, will occur in the morning, and temperatures will fall in the afternoon.  It will be mostly cloudy, and there could be some lingering showers.  Colder air will move in on Thursday night dropping temperatures into the middle 20's.  It will be partly cloudy on Friday, and chilly, with a high only around 30 degrees.
