A Potential Snow Storm Later This Week

Low pressure located near La Crosse, Wisconsin will move to Green Bay by Sunday evening and continue northeast into the UP of Michigan on Monday. It will be cloudy overnight with some light rain possible. No measurable rainfall is expected.   Temperatures will remain fairly steady with a low in the middle 40's. On Sunday the drab weather will continue with clouds and a chance of a little light rain in the morning. The high temperature will be in the middle 40's. It will be mostly cloudy and cooler on Sunday night as winds swing around to the northwest dropping overnight lows down into the upper 20's.  Cold surface high pressure will be in place over the central plains on Monday.  An upper level disturbance passing over central Illinois on Monday afternoon could scatter some light rain showers or sprinkles into the Stateline on Monday afternoon.  It will be cooler, but still above average with highs in the upper 30's.  Skies will be partly cloudy, and it will be a little colder on Monday night with lows in the middle 20's.  Another disturbance could cause some rain or snow showers on Tuesday afternoon, but any precipitation should be minimal.  On Wednesday the high pressure ridge will be well to the east of the Stateline.  A storm system looks like it will beginning to put itself together over the Texas/Oklahoma panhandle area on Wednesday morning.  It will be partly sunny across northern Illinois with a high around 40 degrees.  The low will track toward the east on Wednesday night.  It will become quite intense with strong winds, and rain or snow will develop on Wednesday night.  Right now it appears as if the low will track into central Illinois by 6 am on Thursday morning.  If it travels just a little bit further south, the Stateline looks like it could be in for a heavy snow storm.  With the track through central Illinois it looks like a rain/snow mix gradually changing to all snow as the storm pulls off to the northeast on Thursday afternoon and night.   Friday will be partly sunny, windy, and colder with a high in the middle 20's.  Saturday will be a cold day.  The low in the early morning will be around 12 degrees, and the afternoon high will be around 24.
