Flip flopping weather conditions as we head through this week. We start off with mild but soggy weather today, and end the week with more of a winter chill.
A strong and stacked low pressure system is currently spinning in the Dakotas brings snow for the upper Plains and colder temperatures, while the Midwest is in the warm sector of this system. Ahead of the low southerly winds will strengthen as the low strengthens too, which helps to draw in warm and muggy air from the south. Warm air advection ahead of the low will bring temperatures in the upper 40's and low 50's into Tuesday, but we pair that with periods of rainfall on Monday.
The first round of rain arrived last night and was out of the Stateline before 2am with many towns picking up anywhere between 3/4 to over an inch of rainfall. While there will be a break through the morning hours we aren't done with the rain, another round of off and on rain showers arrives a little before lunch time today and that could add another 3/4 of an inch of rain to those totals.
Rain will continue through midnight before dry air arrives behind our first cold front. We still will notice mild temperatures Tuesday, and it actually looks to be the nicest day we have this week. Drier air brings more sunshine, and breezy southerly winds will help temperatures make it into the low 50's.
The mild air doesn't last long, a second cold front will swing through Wednesday which brings another push of colder air. The front along with multiple waves of energy will rotate through the region will bring a small chance for flurries late Wednesday into Thursday, though no accumulations expected. But, it will feel winter-
like with high temperatures through the week dropping, we'll get highs in the upper 30's by Friday.
