KEY MESSAGES

- Low humidities are expected this afternoon and again Sunday and Monday afternoons. - Temperatures average 5 to 15 degrees above normal through Saturday, and 15 to 20 degrees above normal for Sunday to Wednesday.

- A cold front is forecast to bring isolated to scattered showers tonight into Saturday, but average rainfall from these are expected to be meager.

- Low chances for showers and thunderstorms return for Monday and persist through much of next week as the area will be on the far eastern/southeastern periphery of an active storm track from the Southern Plains to the Great Lakes region.

LONG TERM

(Sunday through Friday) Issued at 247 PM EDT FRI APR 10 2026

The extended period begins with the forecast area under the influence of surface high pressure. A dry warm front, associated with a surface low tracking eastward into the Great Lakes, is progged to lift through the region Sunday morning. This will be followed by rising geopotential heights aloft and the development of a strong LLJ. Within the warm sector, temperatures are forecast to climb into the upper 80s supported by robust southwesterly flow. While LREF wind probabilities highlight the Bluegrass and northern portions of the CWA for the highest potential gusts, a stout inversion is forecast to settle just below the strongest momentum. Without a significant mixing mechanism to overcome this stable layer, surface gusts may remain limited. Consequently, Sunday is expected to be warm with a steady southwesterly breeze. Clouds will increase Sunday night, though conditions remain mild with overnight lows only falling into the low to mid 60s.

The approaching cold front is forecast to undergo frontolysis as it nears the area. Despite this weakening trend, sufficient forcing remains to maintain a 15 to 20% PoP beginning Monday morning and persisting through the day. As the boundary decays and eventually stalls, it will serve as the primary focal point for convective development through the remainder of the forecast period. Precipitation chances will be maximized during the afternoon hours, with activity diminishing toward sunset following the loss of diurnal instability. Some of these storms may be on the stronger side; however, without substantial shear to support longer-lived updrafts, most will be garden variety with gusty outflow winds and heavy rainfall.

Temperatures will remain well above seasonal climatology, appearing more characteristic of July than mid-April. Overall, the forecast period is highlighted by unseasonably warm temperatures and daily chances for afternoon showers and thunderstorms. This convective activity is expected to dissipate each evening, only to undergo diurnal renewal the following afternoon.

AVIATION

(For the 18Z TAFS through 18Z Saturday afternoon) ISSUED AT 210 PM EDT FRI APR 10 2026

VFR conditions are expected through this evening, with high thin cirrus giving way to thickening mid-level clouds from the northwest after 00z this evening as cold front approaches. The potential for MVFR ceilings increases after 06z from the northwest, with the low potential for a few isolated showers impacting IOB and SYM late in the night. Confidence in impacts at the terminals was too low to include mention in this TAF issuance. Southwest to west winds at 5 to 15 kts with some higher gusts this afternoon will decrease with the loss of daytime heating but will veer to a more northerly direction at ~6 kts or less behind the frontal passage.
