Inland Waterway Weather Report
Weather Highlights:
- Upper Mississippi/Red/Souris: A strong low pressure system will move through southern Minnesota and northern Iowa today. As a result, expect widespread precipitation today and tonight. High pressure builds into the upper basin beginning tomorrow night and lingers throughout the week, yielding drier and cooler weather.
- Middle Mississippi Valley: A strong weather system moving across Iowa will bring showers and thunderstorms to the area today and tonight. With these storms, there is a Moderate Risk (level 4/5) for severe weather. The primary threat from these storms are large hail (>2”), strong winds, and a few strong tornadoes (max EF3). The storms push east this evening, allowing high pressure to settle in, allowing for cooler and drier weather through the week.
- Lower Mississippi Valley: The low-pressure system to the north will drag a front across the lower basin tonight and into Tuesday. This front will more or less become stationary and linger over the lower basin through the end of the week. This will bring several bouts of showers and thunderstorms to the area throughout the week. Plan on an Enhanced Risk (Level 3/5) today and a Slight Risk (Level 2/5) tomorrow.
