The jet stream pattern will once again be changing into the weekend and early next week. From the upper 80's to near 90 degrees highs on Thursday, to highs tumbling back down into the 60's by next week, we're gearing up for a bit of a roller coaster ride.
Behind Friday's cold front, skies will remain quiet and partly cloudy. Temperatures will stay comfortable going into the weekend with highs in the mid-70's Saturday and possibly upper 70's on Sunday. This, however, will come with another threat for showers and storms as early as Saturday night. A ridge of high pressure will build in the Midwest while low pressure develops in the Plains. As a warm front moves northwest of the Stateline through Iowa and Minnesota, a few scattered thunderstorms will be possible into Sunday morning. A brief break from the rain may come during the afternoon before additional showers and storms roll in Sunday night and Monday. Monday holds the possibility of severe weather in the Midwest ahead of another cold front that will pass Monday night.
It looks like there will be just a bit more cold air to follow Monday night's cold front - enough that could drop highs back into the low 60's. This would be nearly ten degrees below average. Along with the cooler air, several upper level waves rotating within the jet stream will bring pop-up types showers, and even a few thunderstorms, Tuesday through Thursday. This pattern doesn't look to hold as we should rise back near average towards next weekend.
