As these\n    storms move off of Lake Erie/Ontario later this afternoon and into\n    the evening, some damaging wind gusts are possible, particularly\n    from far northeast Ohio into western New York. Instability is weak\n    due to limited moisture but low-level lapse rates are steep and\n    mid-level temperatures are cold. This may be sufficient to mix down\n    some of the stronger (40 to 50 knot) mid-level flow between 3 and 4\n    km (sampled by the CLE/IWX/DTX/BUF VWPs).\n\n    Some uncertainties remain given the cool Lake Erie/Ontario water\n    temperatures and the aforementioned weak instability. Therefore,\n    watch probabilities remain 40% for now and trends will be monitored.\n    If storm intensity remains consistent as the storms approach this\n    well-mixed airmass, a severe thunderstorm watch may need to be\n    considered.\n\n    ..Bentley/Gleason.. 05/09/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...BUF...CTP...PBZ...CLE...DTX...IWX...\n\n    LAT...LON   41208395 41278428 41748376 42658216 43338130 43538032\n                43477915 43417803 42917810 42297831 41927864 41597932\n                41208045 41048136 41048246 41088320 41208395\n\n    MOST PROBABLE PEAK WIND GUST...55-70 MPH\n    MOST PROBABLE PEAK HAIL SIZE...UP TO 1.25 IN\n\n\n\nRead more",
