Pleasant conditions will continue but a couple of weak cold fronts will move into the area later in the workweek bringing showers/t-storms. The first is currently over the western Dakotas. This will begin to move south and strengthen with time. As this system moves through Thursday, dry ridging begins to build over the southern end of the cold front that is associated, causing a good bit of stability and decaying showers/t-storms as they move into the area early Thursday.
The next system will move through Friday night into Saturday with the same thing occurring to it as well. But most if not all showers/t-storms could dissipate as they move into the area as stability rapidly increases over the front. Moisture return with a normal distribution of showers/t-storms will begin to occur by the start of next week.
