Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0226 AM CDT Sun Mar 16 2025 Valid 181200Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST NEBRASKA...IOWA AND FAR NORTHERN MISSOURI... ...SUMMARY... Thunderstorms associated with marginally severe hail will be possible from late Tuesday night into the early morning on Wednesday from southeast Nebraska into Iowa and far northern Missouri. ...Southeast Nebraska/Iowa/Far Northwest Missouri... At mid-levels on Tuesday, anticyclonic flow is forecast to be in place across the eastern half of the nation, as a trough moves quickly eastward through the Intermountain West and central Rockies. During the afternoon and evening, moisture return will take place ahead of the approaching system from the Ark-La-Tex northward into the mid Missouri Valley. By Tuesday night, surface dewpoints are forecast to reach the upper 40s and lower 50s F within a narrow corridor from far eastern Oklahoma into far eastern Kansas and southern Iowa. Overnight, a cold front is forecast to move through the central Plains and mid Missouri Valley, along which thunderstorm development is expected to take place. Forecast soundings at 06Z to 09Z near the front in far northwest Missouri and far southern Iowa have a low-level temperature inversion up to near 850 mb, with elevated instability located mostly above 700 mb. MUCAPE in the area is forecast to reach the 500 to 750 J/kg range, with effective shear of 30 to 40 knots. Mid-level lapse are forecast to be around 8 C/km. This environment could be enough for marginally severe hail with rotating storms that move along and near the instability axis. The majority of the severe threat is expected late in the period, between 06Z to 12Z early on Wednesday. ..Broyles.. 03/16/2025 Read more

Forecast soundings at 06Z to 09Z near the front in far northwest Missouri and far southern Iowa have a low-level temperature inversion up to near 850 mb, with elevated instability located mostly above 700 mb. MUCAPE in the area is forecast to reach the 500 to 750 J/kg range, with effective shear of 30 to 40 knots. Mid-level lapse are forecast to be around 8 C/km. This environment could be enough for marginally severe hail with rotating storms that move along and near the instability axis. The majority of the severe threat is expected late in the period, between 06Z to 12Z early on Wednesday. ..Broyles.. 03/16/2025 Read more
