From Mount Holly AFD early this morning-
Strong warm advection/isentropic lift and elevated instability will contribute to several rounds of showers, heavy at times, during the bulk of Wednesday as warm front moves northward aloft. That part is key...surface warm front, by contrast, looks likely to end up pretty stuck across the southern Delmarva through Wednesday. It may creep north slightly, but right now the I-95 corridor and points north still look most likely to stay in the relative cool sector, with highs in the 40s to lower 50s. Meanwhile, south of the front, highs surge into the 60s across southern Delaware and the lower eastern shore of Maryland. And this is what could make things more interesting in terms of severe potential as we get into the afternoon and early evening period as the triple-point low develops just to our southwest and tracks along the stalled front into the Delmarva and eventually far southern NJ.Depending on available instability, this could be a focal point for severe weather thanks to the enhanced shear along the warm front. SPC has placed a slight risk of severe weather across our extreme southernmost zones for Wednesday with the MARGINAL risk for severe weather extending a bit farther north through the remainder of Delmarva and then extending east through southern most NJ. Given the very strong shear, forcing, and "thick" CAPE values near 700 mb the set up could result in elevated supercells. Large hail and damaging winds look to be the biggest threats but we can`t rule out one or two tornadoes over southern Delmarva where there will be more in the way of surface instability.
