A shortwave trough crossing the central U.S. will support repeated rounds of convection across the southern tier. Some of these storms will have the potential to become severe today across the Gulf states and Southeast. Scattered to widespread heavy rain will be the main hazard given the influx of anomalous moisture and significant instability into the region. A Slight Risk (level 2/4) of Excessive Rainfall leading to Flash Flooding is in effect for portions of Louisiana to western portions of North Carolina, where the confluence of moisture, instability and lift along the surface front will be greatest. The primary Flash Flood risk pivots into parts of the Southeast and Southern Appalachians while remaining over the central Gulf Coast. The Severe threat remains for the Lower Mississippi Valley and Southeast. The anomalous moisture mentioned above with continue to spread into the Northeast ahead of the approaching low pressure system over the Ohio Valley. Rain showers in the warm sector are likely for much of the Northeast and Lower Great Lakes tonight while freezing rain gets going over parts of Vermont, New Hampshire and southern Maine. Freezing rain accumulations aren't expected to eclipse 0.1". Light snow will occur over central and northern Maine. Conditions should improve by Thursday afternoon for the Northeast. Unseasonably warm temperatures will overspread the East Coast and portions of the Ohio and Tennessee Valleys. Low temperature anomalies between 40-50 degrees above average will lead to widespread records being broken tonight and Thursday night. Elsewhere, low pressure in the West will produce snow showers over the Cascades, Sierra and Rockies over the next couple of days. New accumulations of 4 to 6 + inches are possible today and into Friday - a few isolated areas may exceed 8 inches.
