000 ACUS01 KWNS 200100 SWODY1 SPC AC 200058 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0758 PM CDT Mon Aug 19 2019 Valid 200100Z - 201200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN IA... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS NORTHERN MN... ...SUMMARY... Large hail and damaging gusts are expected late tonight across Iowa and northern Minnesota. ...01Z Update... ...Northern Plains into the Upper Midwest... A thunderstorm or two is still possible across ND and northeast SD as the front moves eastward tonight. Later tonight, increased storm coverage is anticipated along the front as it moves through northern MN. Moderate buoyancy and enhanced westerly flow aloft will result in an environment supportive of strong, organized updrafts. Potential for severe hail and strong wind gusts appears high enough to merit an increase in wind/hail probabilities and a Slight Risk. ...IA... Severe thunderstorms are still expected to develop late tonight amidst ample low-level moisture and a strong low-level jet. Large hail (isolated over 2" in diameter) will be the primary hazard with the initial development with the threat then shifting to strong wind gusts as upscale growth occurs. Primary change over this area was to pull the Slight Risk back farther west (to the MO River) to account for a greater potential for storms farther west. ..Mosier.. 08/20/2019 $$
