Winds of change

Low pressure, cut off from the main flow in the jetstream, will continue it's slow trek northeast this afternoon.  Out ahead of it showers are currently moving through Chicago and southeast Wisconsin with some sunshine trying to break through across the Stateline.  Scattered showers/storms could redevelop again this afternoon as we experience a little more sunshine and as the low moves closer. 


By early next week high pressure will move across the upper Great Lakes giving us more of a northeasterly wind.  This may create what's known as a 'back door cold front'.  Typically a cold front will approach from the west, northwest or north.  A back door cold front is a front that approaches from the east/northeast. This could be the case as winds flow down Lake Michigan and cause the lakes shores to be cooler than surrounding locations. It's possible, though, this front may push further inland across north-central Illinois causing temperatures to fall into the low 60s during the afternoon.  As a result, I did lower high temperatures for Monday to 60°.  Now, should winds not be overly strong we may in fact be a little warmer will places east stay cool.
