Tornado Alley may take a brief jog to the west on Monday afternoon, as a strong upper-level system is set to trigger potentially tornadic storms over parts of eastern Wyoming and western Nebraska. The peak twister risk should only run a few hours before storms congeal into a larger complex, but during that span there could be one or more supercells. Strong tornadoes are possible today, noted the NOAA/NWS Storm Prediction Center in its 11:30 am CDT update.
Other severe storms may occur Monday along a warm front extending east from Nebraska and South Dakota, with a separate pocket of severe weather potential over northern Maine.
The High Plains severe weather will be triggered by an especially strong clash between warm, moist surface air pushing in from the Gulf of Mexico and very cold air aloft sweeping east over the area from the Pacific Northwest. Vertical wind shear will be especially favorable over eastern Wyoming, and the cold air aloft together with relatively moist air at the surface means there should be ample instability even though surface temperatures wont be especially warm (not much beyond about 80°F at best).
