This special Sunday update is to address the threat for severe thunderstorms and the potential of isolated embedded tornadoes in New England on Sunday. In the video, Matt Noyes gives an overview of the timing and stresses how important our Noyes’ 1DegreeOutside Weather app can be – and the best way to configure it. For those who’d rather a written post, Matt has that here:
Enhanced Severe Weather Risk
The Storm Prediction Center in Norman, Oklahoma has placed much of New England under an enhanced risk for severe weather today. The primary threats include:
- Damaging Wind
- Large Hail
- Cloud-to-Ground Lightning
- Tornadoes (isolated risk)
Weather Setup
A warm front is moving across the area today, bringing in warm air and humidity. This setup differs from last week’s storms, which fed off existing heat and humidity. The incoming warmth creates a rotational component in the wind, increasing the risk of severe weather.
Using Our App
One of the most important tools you can use today is our app. Here’s how to stay informed:
- Radar Tab: Use the “past plus future” mode to see the loop of storms up until the current moment and the next few hours.
- Download the App: Available on the Apple App Store (search for “One Degree Outside Weather” or “Noyes”). For Google Play, visit 1DegreeOutside.com and click the Android link at the top of the page.
Detailed Forecast for Today
Midday:
- Warm Front: Moving through with lots of clouds.
- Incoming Humidity: Making the air buoyant and easy to rise.
2 PM:
- Thunderstorms Begin: Starting in Vermont with a high threat for damaging storms and an isolated tornado risk.
4 PM:
- Storm Movement: Storms move into New Hampshire, central and southern Vermont. Isolated storms possible in eastern New England.
5 to 7 PM:
- Peak Activity: Central New Hampshire will see the greatest threat for rotating storms. Damaging winds possible in storms regionwide.
8 PM:
- Follow-up Line: A cold front approaching the Canadian border, with storms weakening by 10 PM.
Tornado and Flash Flood Potential
The greatest tornado potential is in areas with increased thunderstorm energy. By 4-5 PM, the area circled in yellow (Vermont to central New Hampshire) will have the most rotation and the highest tornado risk. Further south, expect more straight-line damaging winds.
Flash Flood Risk:
- Crown of Maine: 4-5 inches of rain expected, increasing flood risk.
- Mountains and Hills: Potential for prolonged rainfall, causing localized flooding.
Safety Tips
- Stay Informed: Keep notifications on our app turned on to receive alerts before storms arrive.
- Stay Safe: Keep shelter nearby in case of threatening weather.
The severe weather threat should subside later in the evening. Stay safe today!
