Pattern Change Next Week Could Bring Big Chills to the Stateline

An abrupt pattern change next week could take our temperatures from the 80's over the upcoming holiday weekend, down possibly into the 60's by the middle of next week.




Heat has been building over the western U.S. and will continue through the end of the week with high temperatures reaching 90 degrees in the interior Northwest, to 100 degrees over California and southwest.  Some of that heat could be pushed east ahead of a cold front into the Midwest and Great Lakes late this weekend.  This may take highs, especially on Monday, into the upper 80's.  Following the warm up, though, a strong low pressure system will develop near Hudson Bay causing the jet stream to dip well south into the Midwest and Great Lakes, pulling a very cold air mass southward.




Locally, high temperatures may struggle to make it out of the 60's following the passage of a cold front Monday night/Tuesday morning.  The chill won't last long, though.  Temperatures look to moderate back near normal into the following weekend.
