Weekend Weather Update

Wow!  What a difference a day makes!  Yesterday nearly all of our weather forecast models had jumped on the southern track bandwagon with our weekend system and now this morning they have trended further north, way north.  The top image was Wednesday morning's GFS run and had the low moving through the lower Mississippi River Valley Saturday afternoon.  The early morning runs have now trended the low right through Northern Illinois/Southern Wisconsin.  The reason for such an inconsistency - this storm isn't even onshore yet!

A more southerly track would have likely yielded a heavier snow accumulation across parts of the area.  With this more northerly track, there is a greater potential for warm air to initially get wrapped into it which would likely keep a mix going at the onset before changing over to snow Saturday night.  If we were to see a mix, snowfall amounts would be reduced and the heaviest of snowfall would likely occur to the north and northwest of the WTVO forecast area.

One thing that has been very consistent through this whole week is the polar arctic air expected to surge in quickly by Saturday night.  Winds are expected to increase through the night into Sunday with temperatures falling into the middle single digits by Sunday evening.  Winds will be gusty dropping wind chills by Monday morning well below zero!!

Be sure to stay with us throughout the afternoon and into tomorrow morning as we continue to get new data in.  Anyone with travel interests should continue to monitor the forecast.
