Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0656 PM CST Wed Mar 05 2025 Valid 060100Z - 061200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE MID-ATLANTIC... ...SUMMARY... Marginally severe storms with isolated severe wind gusts will be possible this evening across parts of the Mid-Atlantic. ...Mid-Atlantic... A mid-level trough, evident on water vapor imagery, will move eastward across the Ohio and Tennessee Valleys this evening. At the surface, a cold front is located in the southern and central Appalachians. Ahead of the front, an axis of low-level moisture is analyzed from far eastern North Carolina northward into eastern Virginia, where surface dewpoints are generally in the 50s F. Thunderstorms are ongoing along the western edge of this moist corridor ahead of the front near a surface trough. This area is also close to a mid-level jet with wind speeds around 100 knots. Near this jet streak, deep-layer shear is strong and large-scale ascent is focused. This environment along with some instability will be sufficient for a marginal severe threat for a few more hours this evening. Isolated severe wind gusts will be the primary threat. ..Broyles.. 03/06/2025
