Showers overspreading the northern Mid Atlantic coast vicinity may continue to be accompanied by strong to severe wind gusts and perhaps the risk for a tornado or two through mid to late evening. ...01Z Update... The sharp surface frontal zone has been steadily progressing east of the Allegheny Front and Blue Ridge Mountains the past few hours, coincident with an area of low pressure within deep surface troughing migrating across northern Virginia into south central Pennsylvania. Along the front near and just south of the wave, a narrow line of convection continues to develop, supported by lift of moist boundary-layer layer air characterized by at least weak CAPE. Due to relatively warm mid/upper levels with weak lapse rates, convection is likely to remain low-topped with little, if any, lightning. However, downdrafts have been sufficient to support the downward transfer of momentum, associated with 50-60 kt southerly mean flow in the lowest 3 km above ground level. Profiles sampled in 17/00Z sounding from Dulles (IAD) appear supportive of at least some risk for a tornado or two. ..Kerr.. 03/17/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
