Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0738 PM CDT Sat Jun 15 2024 Valid 160100Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MID-MISSOURI VALLEY REGION AND THE NORTHERN HIGH PLAINS... ...SUMMARY... Scattered severe thunderstorms with damaging winds and large hail remain possible this evening across the Mid-Missouri Valley, and also from eastern Montana to the western/central Dakotas. A few tornadoes could occur in eastern Nebraska and western Iowa, with isolated significant severe hail and wind possible across parts of the northern Plains. ...01z Update... Early-evening water-vapor imagery depicts a well-defined mid-level vort over north-central KS lifting northeast toward the Mid-MO Valley. Two clusters of severe thunderstorms have evolved ahead of this feature: 1) northeast Nebraska, 2) southeast Nebraska into northeast Kansas. The northeast NE cluster is comprised of several supercells that have generated tornadoes at times. The southern-most complex has evolved into a linear MCS that is tracking toward northwest MO/southwest IA, and is producing severe wind gusts. Both of these clusters are supported by the aforementioned short wave which will encourage an increase in the LLJ across central IA into western WI later this evening. This should allow strong/severe thunderstorms to spread into the Mid/Upper MS Valley after sunset. Upstream across the northern High Plains, strongly diffluent high-level flow is noted across eastern MT into the western Dakotas ahead of a pronounced northern-Rockies short-wave trough. This short wave will shift into eastern MT later tonight as 500mb speed max rotates across northeast MT into southeast SK. Strong/severe thunderstorms will be noted ahead of the surging cold front which should advance across the western Dakotas by 06z. ..Darrow.. 06/16/2024 Read more
