North winds and cooler airmass with overnight lows will fall to around the 30 degree mark.

Cold air advection will be ongoing through the day Monday which will keep afternoon highs in check mainly in the lower to middle 40s. The cold air will be rather dry as well with afternoon relative humidity values around the 30 to 40 percent range, especially

east of Highway 65. This will lead to areas of elevated fire weather conditions.

The dry air will remain in place Tuesday as high pressure builds over the area under upper level ridging. Surface winds will shift out of the south allowing warm air to begin to make its way into the area along with moisture return as well. The ridge will then remain over the region into the middle of the week, with temperatures climbing to near 60 degrees Wednesday, before shifting east Thursday.

A stronger upper level trough/low will move out of the southwest and into plains by Sunday. As this happens, rain will spread into the area in advance of the trough,

through the weekend. With the deep southwesterly flow, temperatures will be in the middle 50s to around 60 degrees. Models are in good agreement that we will be warm and wet as we head into the holiday weekend.
