Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0742 PM CDT Sun Sep 01 2024
Valid 020100Z - 021200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated to scattered thunderstorms will continue into the late
evening and overnight hours from the Mid-Atlantic region into the
southern CONUS, Four Corners region, and Pacific Northwest.
...Summary...
Isolated to scattered thunderstorms are expected to persist into the
early morning hours across parts of the Mid-Atlantic, but the
overall severe threat appears sufficiently low to remove risk
probabilities.
...Mid-Atlantic...
Thunderstorms across the Mid-Atlantic region have shown signs of
steady weakening over the past hour based on regional reflectivity
imagery, MRMS echo-top heights, and cloud-top temperatures. 00 UTC
soundings along the East Coast, and downstream from ongoing
multicell clusters, sampled around 500-1000 J/kg MLCAPE with around
20 knots of mid-level flow. A sporadic strong updraft or two will
remain possible this evening along the outflow boundaries of ongoing
convection given these environmental conditions. However, the onset
of nocturnal cooling will continue to modulate mixed-layer buoyancy
(with an attendance increase in inhibition), which should maintain
the overall weakening trend. Latest CAM solutions support this
scenario with increasingly sparse thunderstorm coverage heading into
the early morning hours. Consequently, the overall severe potential
appears sufficiently low to warrant removing risk probabilities.
