KEY MESSAGES

- Cooler and drier air arrives and settle in through the first half of the week.

- A Frost Advisory is in effect for late tonight into Monday morning. Frost is also possible Monday night and Tuesday night, with a few of the normally colder and sheltered valley locations possibly experiencing a freeze Monday night and/or Tuesday night. - Temperatures climb to 10 to 15 degrees above normal during the second half of the week, with rain-free weather expected.

UPDATE

Issued at 711 PM EDT SUN APR 5 2026

Late day obs were blended into the forecast. Have also lowered forecast min temps for tonight slightly in some valleys, with coldest readings around 30.

LONG TERM

(Tuesday through Sunday) Issued at 251 PM EDT SUN APR 5 2026

Below normal temperatures are expected Tuesday in the wake of the reinforcing cold front Monday evening/night, with highs only reaching the mid 50s north to lower 60s south. Surface high pressure will be moving off to the east, however, and allowing for return southerly flow to develop by Wednesday afternoon. This sets up a good scenario for a larger ridge-valley split for Tuesday night/Wednesday morning, with the potential for frost/freeze conditions once again, particularly in the valleys.

Southerly low-level flow will also support low humidity through much of the week due to a downslope component off of higher terrain to the south and southeast. Significant ridge-valley splits in temperatures are thus expected during the overnight periods through the week, with colder valleys possibly seeing additional rounds of frost formation through at least Thursday night.

Otherwise, the main story of the long-term period will be the lengthy period of rain-free weather extending into next weekend, and the strengthening warm advection resulting in temperatures returning to 10 to 15 degrees above normal by late in the week. Note that these temperatures, especially daytime highs, may trend higher later this week as the deterministic NBM values are currently on the lower side of the probabilistic envelope.

A cold front moving southeast toward the area late week into next weekend may allow for a remote/low chance of showers and thunderstorms Saturday afternoon. However, the vast majority of model guidance at that time frame indicates the activity will remain north of the Ohio River.
