AREA FORECAST DISCUSSION National Weather Service Wilmington OH 1027 AM EDT Sat May 18 2024

SYNOPSIS
Seasonably warm conditions are on tap today. Cannot completely rule out a stray shower or thunderstorm late afternoon through early evening, but most spots should remain dry. Much above normal temperatures and mainly dry conditions are expected for Sunday and Monday, with a chance of showers and storms returning as early as Tuesday. The next widespread chance for showers and storms is likely to evolve midweek, with slightly cooler conditions for the second half of the workweek.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Southern stream mid level trof/low to pass thru the TN Valley today with a narrow ridge building into the region overnight.
Dense fog continues to improve and lift into a stratus deck this morning. This improving trend to continue with stratus scattering out by afternoon and developing into a cu field.

A warm day is on tap with highs in the upper 70s to around 80.
A lack of forcing today but with ML instability approaching 1000 J/KG and mid level trof moving thru can not rule out a few spotty showers or thunderstorms - mainly southeast of I-71. Any convection that does develop will be short lived with rather weak wind flow.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/
Tranquil conditions are expected this evening/tonight once any diurnally-driven spotty SHRA/TSRA activity wanes by about 02z.
Lows tonight dip into the upper 50s and lower 60s once again amidst weak northerly sfc flow. Could see some fog develop in area-river valleys and sheltered locales tonight, but the setup for widespread fog development tonight appears to be less favorable than is the case this morning.

Temps rebound nicely again on Sunday, topping out in the mid 80s with plentiful sunshine (and a few afternoon Cu) on tap.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
On Sunday evening, a narrow ridge of high pressure will extend from the western Gulf Coast through the Ohio Valley, with an axis on a southwest-to-northeast orientation. A surface high over the Great Lakes will be moving off to the east, as the upper pattern shifts into something a bit more progressive by Monday. Broader ridging over the far southeastern CONUS will persist through the middle of the week, but a more active WSW flow pattern will develop on the periphery of the ridge, extending from the central plains through the Ohio Valley.

Monday appears likely to be dry, with any forcing still upstream of the area. By Tuesday, instability will be building into the region from west to east, with deep-layer SSW flow and dewpoints getting well into the 60s. However, forcing will still be mainly upstream of the area, so convection will be limited -- though more likely to occur in the northern and northwestern sections of the CWA, closer to the forcing and further away from the stronger cap to the southeast.

The most active stretch of the extended forecast will be some time Tuesday night through Wednesday night. There is model agreement on a compact upper low moving into the Lake Superior area, with an associated cold front moving across the upper midwest and eventually into the Ohio Valley. The timing forecast for the shortwave and the surface front remain far from certain at this distance in the forecast cycle. One notable change to recent model runs is further displacement of the surface low from the Ohio Valley, which is leading to a more southwest-to-northeast oriented frontal boundary.
This may not be as favorable from a forcing perspective, and winds ahead of the front also appear rather veered (southwesterly) which would limit directional shear if that were to verify. Nonetheless, it is fair to say that instability and deep shear could support a severe threat at some point in this time frame. A drier and cooler air mass will follow the front to end the week, with very low confidence on when the next progressive shortwave may move into the area after Friday.

Monday and Tuesday will be the warmest days of the extended, with highs possibly reaching the upper 80s on Tuesday. As convection and a cold front move into the area, slightly cooler conditions are expected for Wednesday and beyond.

AVIATION /14Z SATURDAY THROUGH WEDNESDAY/
Widespread FG, some of it dense, has enveloped the local area this morning, with the main item of interest being the timing of conditions to improve between 12z-15z. VLIFR/LIFR VSBYs should improve rather steadily/progressively through the first few hours of the TAF period, but a corresponding stratus deck will be a bit slower to lift from VLIFR eventually to VFR late morning. It may not be until 16z until CIGs are able to go completely VFR, especially for KDAY/KILN, but confidence in how quickly the CIGs lift/scatter is rather low at this juncture.

SCT VFR Cu should prevail after 16z with a few spotty SHRA/TSRA possible late afternoon into early evening. Coverage of activity should be very spotty/ISO in nature, so have kept terminals dry for now given expected minimal coverage.

Light/VRB/calm winds will go more easterly and northeasterly during the daytime before going back light/VRB/calm once again toward the end of the period. Some BR/FG will be possible again at KLUK toward daybreak Sunday.

OUTLOOK...MVFR CIGs , along with thunderstorms, will be possible Wednesday into Wednesday night.
