503 PM CDT Sun Oct 16 2016 Latest HRRR runs have been hinting at a cluster of thunderstorms developing from north central South Dakota into south central North Dakota late this afternoon and early evening, along the warm frontal boundary as it moves east. A large-scale upper level low/trough extended from the Pacific Northwest across the Rockies and into the Northern Plains. with a trough extending southeastward to another low over southwestern ND/northwestern SD.
18Z TAFs The upper trough over the region continues to drift eastward. Patchy fog will develop across parts of E TN however, confidence is low that the lower visibility mentioned at KTRI will materialize around sunrise and dissipate shortly after sunrise.
308 PM CDT Sun Oct 16 2016 A broad upper level trough was located across the western US. A shorter wave length upper trough was moving onshore across northern CA and will lift east-northeast across the central Rockies early Monday morning, then into the central and northern high plains by 00Z Tue. !--not sent--! After cold frontal passage Monday night, flow aloft become mostly zonal which leads to a mostly dry forecast for the rest of the week.
The tight pressure gradient ahead of the low, combined with a mixed sounding in the low levels, should bring rather strong and gusty southerly winds Monday evening, diminishing toward morning as the trailing trough and cold front arrive after midnight.

Vertical ascent from a passing upper trough has resulted in the development of scattered convection along the front from Southern Arkansas and into Mississippi. However, the high instability should be enough to promote a risk for isolated severe storms through the evening hours.
