vortex95 Posted 1 hour ago Share Posted 1 hour ago PT time for @weatherwiz b/c 2% spinner risk for CT now! I can see that. Even though winds are unidirectional sfc-aloft, they are quite strong at 925 and 850. 30-50 kt W to E from central CT to ern MA. Anything over 30 kt means spinner business. 30 -50 kt at 850 as well. Attached is GFS sounding for ern CT at 18z. 38 kt 0-6 km shear is enoughs for supercell and 30 kt 0-1 km shear is excellent for spinner potential. HRRR shows large areas of 0-3 km CAPE 100+ so there is your low-level stretching. Classic tropical tor set up where best winds, relatively speaking, are at low-levels.
