The severe threat is expected to remain isolated into the evening hours. DISCUSSION...Multiple discrete storms (possibly small supercells) have been percolating in intensity over the past hour or so, as seen by MRMS mosaic radar data. These storms are traversing a diffuse effective warm front, where at least upper 50s F surface dewpoints and steep low-level lapse rates are contributing up to 500 J/kg of thin MLCAPE. RAP forecast soundings and regional VADs show relatively straight, elongated hodographs, which favor a continued discrete storm mode with persistent enough mid-level rotation to foster some hail production. A couple of strong wind gusts are also possible given the steep low-level lapse rates. The severe threat should remain sparse and localized into the evening hours, when a weakening trend is expected given nocturnal cooling. ..Squitieri/Guyer.. 03/31/2024 ...Please see www.spc.noaa.gov for graphic product...
