Prepare Now Message (PNM): Marginal Risk for Severe Weather – Sunday, 19 October 2025

Clinton County, Ohio – The National Weather Service (NWS) and Storm Prediction Center (SPC) have placed our area under a Marginal Risk (Level 1 of 5) for severe weather on Sunday, 19 October 2025. This means isolated strong to severe storms are possible, with damaging winds being the main concern.

Overview

A strong storm system will move through the Ohio Valley late Saturday into Sunday. A powerful upper-level jet stream will help strengthen a surface low pressure area moving across the Great Lakes, pulling a cold front through Ohio. Ahead of this front, southerly winds will bring in warmer, more humid air, allowing scattered thunderstorms to develop late Saturday night and continue into Sunday.

Timing

• Saturday Night: Showers and isolated thunderstorms likely after 8 PM, becoming more widespread overnight.

  • Low: Around 56°F

  • Winds: South 13–17 MPH, gusts up to 29 MPH

  • Rainfall: 0.25–0.5 inches possible

• Sunday: Showers and thunderstorms likely through mid-afternoon, then tapering off by evening.

  • High: Around 66°F

  • Winds: West 23–26 MPH, gusts 35–45 MPH possible

  • Rainfall: Additional 0.5–0.75 inches possible

Primary Hazards

• 🌬️ Strong Winds: Gusts may reach 40–45 MPH, capable of knocking down small branches or causing scattered power outages.

• ⚡ Isolated Severe Thunderstorms: Damaging wind gusts and brief, isolated tornadoes cannot be ruled out in embedded storm lines (QLCS-type).

• 🌧️ Heavy Rain: Periods of moderate to heavy rain may lead to ponding on roads and reduced visibility.

Prepare Now

• Secure loose outdoor items (trash cans, decorations 🎃, lightweight equipment).

• Charge phones and portable power banks tonight in case of isolated power outages.

• Avoid travel during the heaviest rain or strongest winds if possible.

• Stay weather-aware and ensure Clinton County Emergency Alerts (CCEA) are enabled on your phone.

• Check on neighbors or relatives who may not receive alerts or have mobility issues.

Summary

This will be a windy, wet Sunday with the potential for isolated strong storms. While widespread severe weather is not expected, a few stronger cells could bring locally damaging winds. Conditions will improve late Sunday as the front moves east and cooler air settles in.
