KEY MESSAGES

- Dry and mild conditions through Wednesday, followed by a warming trend and returning light rain chances late in the week.

DISCUSSION

Issued at 254 AM EDT Tue Mar 24 2026

Upper level pattern currently consists of ridging over the western CONUS and troughing over the eastern. An H85 high pressure center will slide across the southern Appalachian region as a weak vort max swings through the northern Great Lakes over the next 12 or so hours. High clouds will return for the AM, though, low RH throughout lower levels will hinder precip at the surface. Continued seasonal temperatures with clearing skies are expected this afternoon.

Mild temperatures and dry conditions continue Wednesday as the general synoptic pattern remains fairly persistent, with just minor fluctuations in the overall amplitude of the trough/ridge. Temperatures trend warmer among H5 height rises downstream of a PNW shortwave Thursday. A slight uptick can also be noted in westerly H85 flow Thursday. NBM promotes a dry forecast at this time, but cannot totally rule out low chances for light rain potentially making way into future forecasts.

The aforementioned shortwave will continue eastward Friday, eventually promoting a cold front moving through the Ohio Valley and into the Tennessee Valley region late Friday. Current trends are for this to be a weak frontal passage being so far displaced from the parent low well off the Northeastern Seaboard. Drier and breezy conditions filter in behind the front on Saturday, which could pose heightened fire weather concerns for those that do not get rain Friday night(southern valley). Warming trend expected late weekend into the new work week.
