Severe storms are not expected. * Dry weather, seasonable temperatures and lower humidity midweek through this weekend. && .DISCUSSION... Issued at 352 AM EDT Tue Jul 16 2024 Mature MCV now into southeast MI has forced an active trailing composite outflow boundary south into central IN/IL. This will likely remain the focus for more additional activity today into tonight, though will have to monitor for widely scattered convection to redevelop locally as moderate diurnal instability takes place on the northern fringe of the stable bubble and incoming synoptic cold front. Shear and instability parameters do not support organized severe convection. Dry and seasonably humid otherwise today. An upper level trough will amplify southeast through the Great Lakes Wednesday into Wednesday night with low chances for a few additional showers along the associated synoptic cold front. A low level anticyclone then follows in behind this front through this weekend with comfortable humidity and dry conditions. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
