A Cold Start to the Week

A cold front passed through the Stateline earlier today. There was not a drop in temperatures immediately following the front, so the afternoon high was able to reach a seasonal high of 42 degrees. Colder air is moving in behind the front tonight in advance of a cold Canadian high moving into North Dakota. It will be partly cloudy ovenight with a low in the low 20's. The wind will be fairly light from the northwest at 5 to 10 mph. On Monday cold air will continue to feed into the area from the northwest all day at 10 to 15 mph. Skies will be partly cloudy  with an afternoon high only around 29 degrees. The average high this time of year is 42 degrees.  The center of the high will reach Sioux City, Iowa by 6 pm Sunday clearing skies for Sunday night, which is expected to be the coldest night so far this season with a low around 14 degrees.  The high pressure ridge will settle slowly southward across the area on Tuesday. Skies will be partly to mostly sunny, and it will continue cold with the high temperature only around 33 degrees. With much of the cold air depleted across southern Canada and the northern plains, the next high moving in from the northwest will not drop temperatures. On the contrary, the high on Wednesday will edge up a few degrees to around 37 degrees under mostly sunny skies. The moderating temperature trend will continue on Thursday, which will start off mostly sunny, but some clouds will develop by afternoon. The high on Thursday will be in the low 40's. A front will slide across the area from the north on Thursday afternoon, and become stationary east west across central Illinois. There will be a slight chance of some light rain mixed with some wet snow flakes on Thursday night, and a chance of showers on Friday.  With the clouds and the threat of rain on Friday temperatures will top out in the low 40's once again.  There is also the possibility of dense fog some time between Thursday night through Saturday morning with the Gulf of Mexico opening up.  The warmer and moist air riding up over the cold ground from the recent cold spell will provide an environment where thick fog could develop. It will be milder on Friday night with a low in the middle 30's under mostly cloudy skies.  It will be warmer on Saturday under mostly cloudy skies.  November wraps up at midnight on Friday night  On December 1st the high will be be near 50 degree with a chance of showers. Sunday looks like it will be even a little warmer with a high in the low 50's under partly cloudy skies.
