KEY MESSAGES

- A warming trend continues, with highs returning to the mid 70s to low 80s Sunday.

- Periodic chances for showers and thunderstorms return to the area this weekend, with the greatest chances Sunday night.

- Frost is possible late Monday night into Tuesday morning in valleys mainly away from mainstem rivers.

LONG TERM

(Sunday through Friday) Issued at 254 PM EDT FRI MAY 8 2026

The period begins Sunday morning with a closed low in the vicinity of southern Hudson Bay, with a longwave trough over much of the northeastern quadrant of the country, including the Ohio Valley. Meanwhile, at the surface a cold front will be moving southeast through the Ohio River Valley.

The cold front will cross the area Sunday and bring shower chances and the low chance of a thunderstorm or two Sunday afternoon into early evening. This will be followed by the passage of an upper shortwave moving through the larger longwave trough beginning to exit to the northeast. This feature will bring another round of widespread post-frontal shower activity Sunday night before exiting to the east Monday morning.

Northwesterly flow aloft and surface high pressure will bring clearing skies Monday with highs only reaching the mid-60s, not quite ten degrees below normal. With excellent radiational cooling conditions Monday night, temperatures should fall well down into the mid-30s to lower 40s. While mainstem river valleys are likely to be foggy, outlying valleys may be cold enough for at least some patchy frost.

Temperatures remain near or below normal through the week under northwesterly flow aloft, with warmest conditions Wednesday just ahead of a cold front that will bring roughly 30 to 60 percent chances of showers, and perhaps a few thunderstorms, late Tuesday into Wednesday. After a brief slight cooldown Thursday, temperatures rebound to near normal in the mid to upper 70s ahead of building mid-level geopotential heights Friday.

AVIATION

(For the 18Z TAFS through 18Z Saturday afternoon) ISSUED AT 152 PM EDT FRI MAY 8 2026

VFR conditions are expected through the TAF period. Current satellite shows clear skies across the area, though clouds will overspread the area after 00Z this evening from a disturbance passing to the north. While chances remain extremely low, a sprinkle or an off shower can't completely be ruled out at KIOB and KSYM overnight. Cloud decks may lower to 5k feet or so but should remain in VFR. Winds will be light and variable to begin the period, becoming south to southwest at less under 10kts after 00Z. Winds will increase to end the period with gusts 15-20 kts nearing 18Z.
