yoda Posted July 28 Share Posted July 28 Afternoon AFD from LWX mentioned it DISCUSSION... KEY MESSAGE 1...Severe thunderstorms are possible through this evening, along with a local flash flood risk. MCV over central PA and cold front approaching from NW PA (and general height falls within the upper trough) will serve as forcing to continue the development of widespread showers and thunderstorms this afternoon. Shear will be sufficient for supercells, but cluster and bowing segments may eventually dominate, presenting a risk of damaging winds. Discrete storms will have potential for hail as well. A tornado threat may evolve later this afternoon/early evening as a low level jet pivots into the area and the trough takes on a negative tilt. The axis of storms will likely be closer to the I-95 corridor by this time, where winds could also be backed a little more closer to the bay. At the moment, this threat appears a little more isolated and uncertain, but discussion was had with SPC that some areas could be upgraded to a Tornado Watch should discrete storm modes dominate. The forcing features listed above could also lead to some upscale growth or training as the storms get closer to the bay. This might lead to a few instances of flash flooding, especially from Baltimore to the northeast, as precipitable water values approach 2 inches. A Flood Watch remains in effect for this area. Thunderstorms will likely clear off to the east by 10 PM, although there may be a few lingering showers, especially along the Alleghenies. 1 Link to comment Share on other sites More sharing options...
