701 ACUS11 KWNS 231929 SWOMCD SPC MCD 231929 MEZ000-232100- Mesoscale Discussion 0913 NWS Storm Prediction Center Norman OK 0229 PM CDT Thu May 23 2024 Areas affected...Parts of southern/eastern ME Concerning...Severe Thunderstorm Watch 292... Valid 231929Z - 232100Z The severe weather threat for Severe Thunderstorm Watch 292 continues. SUMMARY...Some threat for hail and damaging wind will spread eastward through the afternoon. DISCUSSION...A line of strong to potentially severe thunderstorms is ongoing from southern into northeast Maine this afternoon. The immediate downstream environment remains somewhat favorable for organized convection, with MLCAPE approaching 1000 J/kg and modestly favorable deep-layer shear (as noted on the 17Z/18Z CAR/GYX modified soundings and regional VWPs), and some threat for hail and damaging wind will continue into late afternoon. With cooler onshore flow noted over the Downeast Maine vicinity, some weakening will be possible with time as storms move into this region. However, sufficient elevated buoyancy may still support some threat for isolated marginal hail and/or a strong/damaging gust before storms move offshore. Isolated storm redevelopment also remains possible into southern ME behind the outflow, though at this time any severe threat with this redevelopment is currently expected to remain marginal and isolated. ..Dean.. 05/23/2024 ...Please see www.spc.noaa.gov for graphic product...
