DISCUSSION
Issued at 123 AM EDT Thu Mar 19 2026
Our return to another brief spell of warm weather is now well underway, with Sunday getting a tad closer (but still under) daily record highs. Before we get to Sunday though, two distinct shots for isolated rain occur. Southwest Virginia may see rain showers as an impulse in the Mid-Atlantic trough swings through with upper jet support Friday night. Then a weak shortwave will slide across the Mid South on Saturday, with an environment late Saturday afternoon or evening supportive of a thunderstorm or two. Coverage should be fairly isolated though nearly all of the medium range guidance (including the long range CAMs) show a shower or storm during the PM hours on Saturday.
Cold front still looking to arrive early next week, but only negligible rainfall expected. Bigger thing from the front will be to cool us down to just mild temperatures, and to impart a significantly drier airmass in its wake. Heading into midweek next week return flow, ah, returns and begins to slowly raise dewpoints and temperatures as we reach late week. No significant weather expected through the next 7 days.
