Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF IOWA THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER MIDWEST AND CENTRAL/SOUTHERN PLAINS SUMMARY Severe thunderstorms capable of producing severe/damaging winds and large to very large hail are likely late this afternoon and evening centered across much of Iowa. Isolated to scattered severe hail and damaging winds are possible over a broader area from parts of the southern High Plains to the Upper Midwest. 20z Update Central Plains Several areas of thunderstorm development are expected this afternoon and evening across the central Plains and Midwest. Moderate instability beneath 40+ kt of mid-level flow will promote a mixed mode of supercells and eventually linear clusters. Hail (some 2+ inches) along with damaging gusts appear likely with the more robust supercells initially along the cold front across NE/northern KS, and farther north along the warm front into southern MN. Eventual upscale growth into one or more linear clusters should favor an increase in the threat for damaging gust and a couple tornadoes over parts of IA, IL and southern WI this evening. Eastern NM/CO and the TX/OK Panhandles Initial high-based shower and thunderstorm development is underway coincident with very strong heating and the arrival of a weak upper-level shortwave trough atop the well-mixed air mass west of the dryline. With mixing depths of 4-5 km below modest buoyancy, strong to severe gusts are possible with these showers and thunderstorms across the southern High Plains. Wind probabilities were shifted slightly west. See MCDs #723 and #724 for short term information.
