High pressure will build over the southwest causing temperatures to soar well past 100 degrees in many locations from California all the way to west Texas. Excessive Heat Warnings and Heat Advisories have been issued - some of which last all week long! Further north over the center of the country the flow within the jet stream will move more west to east - or what meteorologists call 'zonal' flow. This will keep the extreme heat from making it this far northward, but also allow several upper level disturbances to move through the Midwest and Great Lakes. And as each wave of energy passes through, the threat for rain will increase. Right now it looks like the greatest chance for rain - some of which could be quite heavy - arrives Thursday afternoon into Friday. A cold front will come down from the northwest during the day on Thursday. This front will then stall because the winds within the jet stream will be running parallel to the cold front. This won't allow the front to move much during this time and could bring heavy rainfall to *parts of the Stateline. Best case scenario would be for the front to shift south Friday morning, taking any of the rainfall with it. A few forecast models do offer up that solution.
By the end of the week temperatures are expected to cool into the 70's, with the low 70's expected for the weekend. It does look like June may end slightly cooler than where our average highs should be, which are in the low 80's. A far cry from how the beginning of the month started.
