tornado_master Posted July 18, 2023 Report Share Posted July 18, 2023 (edited) Les veilles d'orages violents sont sorties pour les régions de la Montéregie/Estrie/Beauce Mesoscale Discussion 1614 NWS Storm Prediction Center Norman OK 1111 AM CDT Tue Jul 18 2023 Areas affected...Eastern New York...Northern and Western New England Concerning...Severe potential...Watch possible Valid 181611Z - 181815Z Probability of Watch Issuance...40 percent SUMMARY...Widely scattered strong to locally severe storms are expected this afternoon. It is unclear if coverage of storms will warrant a severe thunderstorm watch. DISCUSSION...Visible satellite imagery shows mostly clear skies across eastern NY and much of New England, where dewpoints are in the mid-upper 60s. This warm/humid air mass will yield afternoon MLCAPE values of 1500-2000 J/kg and rather steep low-level lapse rates. A shortwave trough over western PA will provide large scale forcing for ascent across the region, leading to widely scattered thunderstorm development. Forecast soundings show that the strength of the winds aloft and thermodynamic parameters look favorable for a risk of damaging winds in the stronger storms that can form. However, most recent CAM solutions suggest that coverage of storms will be somewhat limited. Satellite/radar trends will be monitored through the early afternoon, with a severe thunderstorm watch issuance possible.
