.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.
