KEY MESSAGES

Updated at 129 AM EDT Thu May 28 2026

- Lower chance of showers today, mainly across southern sections.

- Rain chances persist through the weekend, but a dry weather pattern develops next week.

DISCUSSION

Issued at 129 AM EDT Thu May 28 2026

Showers are currently tracking southeast across the area, associated with a pre-frontal trough that will slowly push through the area overnight. Convergence along the trough in the moist air mass will keep at least some isolated showers through most of the night. This boundary will be near our southern border by sunrise, while the trailing cold front will be entering our northern sections. Surface dewpoints will remain in the 70s south of the front, so some scattered to isolated showers can be expected tomorrow, mainly near the front. A northerly flow through the low levels and some drier air aloft will limit coverage and intensity of convection. NBM PoPs will be cut back.

Friday looks to have pretty limited rain chances, with the best chances in southern sections as the axis of deep moisture will be across GA/N AL/West TN, with midlevel ridging over our area. Forecast soundings look rather stable as well, with only weak CAPE present in the southern half. The axis of moisture returns northward on Saturday as PW values return to the 1.6-1.8 inch range, and a midlevel trough moves over the area.

Sunday into next week could bring some drying out to the region as we sit on the southwest side of a deep trough/low meandering through the northern portion of the United States. This slow moving system means we'll be under generally drier northwesterly flow through much of the atmosphere. Surface high off the Atlantic coast could still draw up some low level moisture, but this pattern would typically indicate less chances for rain over the end of the weekend and into next week. In addition temperatures ever so slightly cool by a couple of degrees for the first half of next week under this system.

AVIATION

(06Z TAFS) Issued at 129 AM EDT Thu May 28 2026

Conditions are currently VFR across the region with mostly thin, high clouds present. Conditions are better for fog development than the last several days. Patchy fog is likely in the early morning hours and dense fog cannot be completely ruled out. VFR conditions will return by mid morning. The best chance of a shower or storm will be near CHA, mainly in the afternoon.
