SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1235 AM CDT Tue Oct 25 2022 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not currently expected on Wednesday. ...Synopsis and Discussion... A pair of shortwave troughs are expected within the broadly cyclonic flow anticipated across the CONUS early Wednesday. The easternmost shortwave trough is forecast to begin the period over the middle OH Valley before quickly moving northeastward across the Lower Great Lakes region and weakening. Warm-air advection ahead of this shortwave may result in a few isolated thunderstorms along the New England coast, but the highest thunderstorm chances will remain offshore. An occluded surface low associated with this eastern shortwave will follow a similar track, with an attendant cold front sweeping eastward as it does. Stable conditions are expected ahead of this front along much of the Eastern Seaboard. The only exception from the Southeast Coast into FL, where modest low-level moisture and limited buoyancy will remain. A few isolated thunderstorms are possible on the front as it moves through these areas. The westernmost shortwave trough will likely begin the period over the interior Pacific Northwest before dropping southeastward through the Great Basin towards the Four Corners. Cold mid-level temperatures will accompany this system and a few lightning strikes are possible within any deeper, more persistent updrafts. However, relatively cold thermodynamic profiles should keep thunderstorm coverage below 10%. ..Mosier.. 10/25/2022
