For this coming Monday, a shortwave trough is forecast to move into the central Plains. Models indicate that a narrow, and increasingly limited, band of moisture will be present ahead of the trough and associated surface front. Though thunderstorms are possible in parts of eastern Kansas with this activity, severe weather potential appears low at this time. As the central Plains trough moves east, it is expected to lose amplitude and eventually phase with a stronger, broader upper trough moving through the Upper Midwest and Ohio Valley region around the middle of next week. While models begin to diverge on the upper-level pattern at that time, the general consensus is for a cold font to push into parts of the southern Plains as well as to near the Gulf Coast and off the Atlantic Coast. With moisture ahead of the front still looking limited, severe thunderstorms do not appear probable along the boundary. Thereafter, surface ridging in the eastern third of the CONUS, along with another upper ridge over the Divide, will keep severe weather potential low through at least the end of next week and possibly into next weekend. ..Wendt.. 10/18/2024
