High pressure will work into the area tonight and allow for dry conditions through Wednesday. Showers and thunderstorms will return for Thursday and Thursday night as a cold front approaches and moves through the region. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... A few showers have been on radar overnight and cannot rule out additional isolated light showers for the remainder of the overnight hours and into the daytime morning hours with a frontal boundary working into the region. Expect most of the fog activity early this morning to be confined to eastern and southeastern portions of the forecast area. As the day progresses the cold front will work through the region. There will be some instability across locations primarily southeast of Interstate 71 today. Thunderstorms are generally expected to be confined to locations along and southeast of Interstate 71 this afternoon. Any precipitation across the region is expected to taper off by this evening. With the front working into the region today expect temperatures to be cooler with highs in the middle 70s across northwestern portions of the forecast area to middle 80s across southern portions of the region. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/... High pressure will work into the region tonight and remain across the area for the short term period. Tranquil weather conditions are expected along with cooler than normal temperatures for this time of year. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Ridge of high pressure will continue to extend across the region into Wednesday with dry conditions and nearly seasonal temperatures. A short wave will drop southeast through the Great Lakes on Thursday pushing a cold front towards the area. Showers and thunderstorms will increase in coverage through the day and continue into the evening. As the cold front moves through Thursday night, precipitation will end. Upper level long wave trough will become established and persist through the weekend. At the surface, high pressure will remain centered to the northwest of the area bringing a prolonged period of northeasterly winds.

Fog this morning will improve as the morning progresses. There are some isolated low cigs around and there will be the possibility of these briefly moving in the TAF sites this morning. In addition later today some MVFR cigs may work into the TAF sites. Believe these will be more isolated in nature and therefore went with VFR conditions later today. A cold front will move through the TAF sites today. Although isolated showers and storms will be around the region, with the isolated nature of the precipitation did not include in the TAFs. Cloud cover will decrease this evening after the passage of the frontal boundary. Some fog will be possible then tonight at KLUK. There is also the potential for fog at the other area TAF sites tonight as well, but with drier air moving in kept fog mention to the more fog prone KLUK site. OUTLOOK...Thunderstorms will be possible Thursday into Thursday night.
