LONG TERM

(Thursday through Tuesday) Issued at 249 PM EDT TUE APR 14 2026

The long term period opens Thursday with a shortwave over the Mid- Mississippi Valley and Upper Great Lakes. As this system lifts northeast throughout Thursday shower and thunderstorm chances increase heading into the late afternoon and early evening. Southwesterly winds and warm air advection allow for temperatures to warm into the 80s through the afternoon, some 10-15 degrees above normal. As showers taper off heading into Friday morning, temperatures cool into the low to mid 50s in valleys, and low 60s along ridge tops.

A ridge of high pressure briefly builds over the area ahead of a deepening trough over the Rockies and Northern Plains. Relatively quiet weather is expected, with a mix of sun and clouds, and temperatures warming into the 80s. Because of the approaching system, clouds begin to increase overnight and through Saturday. Low temperatures Friday night cool into the 50s and low 60s. Saturday, the upper level trough will be over the Upper Great Lakes, with a warm front extending through the Great Lakes into the Mid- Atlantic, while a trailing cold front will extend through the Upper MidWest, the Mid and Lower Mississippi valleys, with showers and thunderstorms along and ahead of it. Shower and storm chances will increase over Eastern Kentucky from northwest to southeast through the afternoon into the evening and overnight hours. Showers and storms are then expected to taper off from northwest to southeast through Sunday. Temperatures Saturday, ahead of the cold front, will warm into mid to upper 80s for most, under southwesterly winds. At night, with winds becoming west to northwesterly, cold air advecting in behind the cold front will cool temperatures into the mid to upper 40s.

Sunday, as remaining showers taper off, the cold front is modeled southeast of the area. Temperatures will be much cooler across the area, some 20-25 degrees cooler in fact, ranging in the low to mid 60s. Clouds should diminish through the afternoon as the trough begins to depart the area. However, Eastern Kentucky looks to be on the backside of the trough heading into Sunday night. With cold air still advecting in under light northwesterly winds and clearing skies, temperatures are expected to drop into the mid to upper 30s in the valleys and lower 40s elsewhere.

High rises look to occur Monday, leading to mostly sunny skies, and highs in the low to mid 60s. Temperatures remain depressed under northwesterly winds. At night, temperatures cool into the upper 30s to near 40. Tuesday, a shortwave looks to skirt through the Upper Great Lakes and its main effects should remain north of the area. conditions will feature a mix of sun and clouds under southerly winds and seasonable temperatures warming into the low 70s.

AVIATION

(For the 18Z TAFS through 18Z Wednesday afternoon) ISSUED AT 205 PM EDT TUE APR 14 2026

VFR conditions prevailed at TAF issuance and should prevail through the period. The region will remain in the warm sector between a sfc ridge of high pressure extending from the Southeast to the western Atlantic and a frontal zone from New England across the Great Lakes and into the Plains. Meanwhile, upper level ridging should remain from the eastern Gulf into the southeast and parts of the Atlantic while the axis of an upper trough moves into the Central Conus. A passing disturbance could bring a shower or stray storm with brief sub VFR conditions during the first few hours of the period to KSYM, KIOB, KJKL, and KSJS. Otherwise, in between the sfc systems, south to southwest winds should average between 5 and 15KT with some gusts to around 20KT for the first few hours of the period. Low and mid level clouds are expected to decrease this evening while winds should also diminish around 00Z with the loss of daytime heating.

South to southwest winds should pick up again into the 5 to 12KT range from around 14Z to the end of the period as the nocturnal inversion mixes out. A few gusts to around 20KT are also possible.
