DISCUSSION

Issued at 254 AM EDT Tue Mar 24 2026

Upper level pattern for much of the forecast will be characterized by ridging southwest into the western Gulf coast states and troughiness over northeast United States. This pattern will keep a predominant northwest to westerly flow aloft. Main storm track will be north of the region and persistent surface ridging across the Gulf coast states will keep QPF amounts generally less than 0.25 inch. Worsening drought conditions will be a concern especially for southeast Tennessee and southwest North Carolina.

For the rest of Today and Wednesday, surface ridging and dry northwest flow will keep conditions dry and mild conditions. Mainly concern will be the low afternoon relative humidity values in the teens and 20s.

For Thursday, a weak short-wave will move across the lower Ohio valley into the central Appalachians. Scattered showers and possibly a thunderstorm will move across these areas and may effect southwest Virginia. Otherwise, surface ridging will continue.

For Friday, a weak frontal boundary with limited jet dynamic forcing will produce scattered convection into the region late in the day. Due to continued surface ridging across the Gulf, boundary layer moisture will be quite limited keeping rainfall amounts light. Ensemble projects no more than 0.10-0.20 inch mainly along and north of interstate 40.

For Saturday and Sunday, zonal flow and continued surface ridging will produce dry and mild conditions. Building ridge over the southeast United States for Monday and Tuesday will produce a warming trend.
