Partly cloudy skies during the morning hours will become overcast in the afternoon. A stray shower or thunderstorm is possible. High 89F. Winds SW at 5 to 10 mph..
A tricky situation in store for your Thursday here in Putnam County. Our second cutoff low of the month is trying to slide eastward into the Mid-Atlantic and Northeast. After a couple days of showers and storms, a rush of warm air and moisture is starting to rise northward out of the Gulf. This will provide a summer-like feel outside. With highs in the 80s, the sticky warm feeling to the air could be a sign of trouble.
The greatest moisture and storm ingredients are moving through Indiana and Kentucky. One limiting factor to any storms, though, lies high up in the sky. A capping inversion, or a temperature increase with height, is forming clouds but preventing storms to rise from the ground and take in all available energy. With this, there is plenty of wind shear, or directional change of winds with height. This could point toward trouble if a boundary of wind from a remnant storm pushes into the region as that could push an air parcel above this cap and create a gusty thunderstorm.
However, with warm highs in the 80s and mostly cloudy skies with sticky conditions, letÃÛÁÄÖ±²¥™s keep an isolated strong storm in the forecast.
While that was a real mouthful for your otherwise summer-like Thursday, Friday has the chance to turn even warmer out there! Some spots from Huntington and westward have a chance to hit 90 for the first time this year! The difference here, though, is a big drop in humidity. Dew points in the 50s to near 60 are much easier on the body than above 60.
The pea soup feeling is gone, but we still have to keep an eye on the sky. A familiar low pressure system with a key triple point will push out of Minnesota and Michigan into Canada. The triple point represents our warm and moist air mass and its border with a cooler air mass into the middle of the country. Scattered showers and a few thunderstorms will arrive during the afternoon and evening. There is the chance for a scattered threat of severe hail, damaging wind, and perhaps a tornado. Storm timing here will depend on how fast the threats are able to break the northern plains and enter the Ohio Valley. This could end up being a marginal early morning storm chance or even a more severe afternoon or evening storm chance if the 90s and plenty of sunshine are able to set in. In the event of a morning storm chance, that would keep much of Putnam County stuck in the 80s for the day.
Heading into the weekend, there is some forecast uncertainty. Behind FridayÃÛÁÄÖ±²¥™s storm front, a trough of low pressure and cooler air in the 70s may try to sink down from Canada. This would be a refreshing blast of comfort, but showers and a few thunderstorms would still be possible in this setup. While any storm could bring 30-plus mph winds, the more likely outcome if we stay north of the trough is just a few showers. If the ridge to our south moves back in, we could be talking about the upper 80s, the moisture, and scattered storm chances for quite some time! The problem here is the northern edge of the ridge could carve the path for multiple convective systems, which means that clusters and lines of storms with gusty winds could travel for hundreds of miles along the path. LetÃÛÁÄÖ±²¥™s hope the trough can keep us comfortable and clear of these nasty storms to close out the weekend.
On the long range, there is some chance the southern stream pushes in by Monday and Tuesday. While exact storm timing and risks are still unknown at this point, look for highs to return to the 80s and the summertime feel to settle in around here approaching the Memorial Day Weekend. Get those air conditioners ready!
