Isolated severe thunderstorms are possible on Tuesday into Tuesday evening along parts of the East Coast, from southeast New Mexico to south Louisiana, and along the lee of the Montana Rockies. ....Synopsis... A broad large-scale trough over ON/QC into the Great Lakes/Northeast will dampen over the CONUS portion with weakly rising mid-level heights. Minor mid-level impulses/MCVs may drift east in the weak southern stream from the southern High Plains to the northwest Gulf Coast. A lower-amplitude shortwave impulse should reach northern CA by early Wednesday. ....East Coast... Severe potential should be confined to the late morning and afternoon period ahead of a weakening cold front. Appreciable Boundary-layer destabilization is expected to remain displaced south of stronger deep-layer shear north. Where there may be lingering MCV flow enhancement in the Mid-Atlantic region, nearly moist-adiabatic thermodynamic profiles should marginalize severe potential. Decreasing deep-layer shear with southern extent along the Atlantic coastal plain should foster a more localized damaging wind threat compared to prior days. ....Southeast NM to south LA... Relatively weak to modest deep-layer shear overlapping the generally west/east-oriented portion of prior large-scale outflow intrusion on D1, may foster sporadic severe hail/wind on Tuesday afternoon and evening. Guidance generally hints at greater thunderstorm coverage from southeast NM into the Trans-Pecos and separately from southeast TX to south LA. ....Lee of the MT Rockies... As mid to upper-level flow becomes more westerly with moderate speed shear, a couple lower-end/high-based supercells may develop off the higher terrain of western to south-central MT. Weak buoyancy suggests that marginally severe hail and locally strong gusts should be the main threats. ...Grams.. 06/08/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
