JAMESTOWN – Another round of showers and thunderstorms are expected Sunday; and a couple of them could be on the stronger side.
The NOAA Storm Prediction Center has outlined much of the Southern Tier of Western New York under a less-than-average “Marginal” Risk (1/5) for severe thunderstorms on Sunday. The primary threat will be from damaging winds but a small touch of hail could also be possible.
The setup: A deepening area of low pressure will track to the northwest of the region on Sunday. Rain showers are likely through the day with a couple rumbles of thunder. The rain throughout the afternoon should not be an all-day rain with pockets of on-again, off-again showers.
A squall line of showers and thunderstorms will develop along the passing Low and will move into Western New York through the evening. Based on the newest data, the main timing window for this line will be between 7 and 10 PM.
Recent data has been suggesting the line will take on a bow-shaped appearance as the squall moves east through the region. With this indication, that will further support the straight-line wind impact. Here are frames from a high-resolution computer model we have in the weather center that clearly shows the progression of the squall line through Western New York:
Be sure to have a way of getting weather warnings. A good way to receive warnings is via a NOAA Weather Radio. These receivers can be picked up quite easy and normally cost around $25.
Beyond the weather radio, have a good smartphone app that pushes vital info. We recommend:
