KEY MESSAGES

- A warming trend will begin today and last through Friday

- The next expectation of area wide rain is not until the weekend.

LONG TERM

(Wednesday night through Monday) Issued at 740 AM EDT TUE APR 21 2026

The aforementioned frontal boundary in the short term segment will be stalled in IN and OH at the start of the period and will begin a northward retreat Wednesday night. Upper level ridging arriving from the west will result in warm and dry weather for the local area into the day Friday. A series of shortwave troughs coming out of a degrading western CONUS longwave trough will then eat away at the ridge. Low level moisture should also finally creep higher as surface ridging/high pressure over the southeast CONUS weakens and shifts offshore. The combination of waves aloft, lowering geopotential heights, and increasing low level moisture should finally allow for rainfall for most of the area, with the most likely time being Friday night into Saturday.

AVIATION

(For the 12Z TAFS through 12Z Wednesday morning) ISSUED AT 740 AM EDT TUE APR 21 2026

VFR conditions will persist through the period. Southwesterly winds will gust near 20 kts west of the foothills this afternoon.
