... Dry and warm weather is expected into Monday under a ridge of high pressure.
NEAR TERM /THROUGH TODAY/... No changes to the overnight period.
The forecast area will be situated within broad 500mb high pressure building over the Ohio River Valley. Light, easterly flow will moderate temperatures today, but with lots of sun, another day of above average temperatures is on the menu. All in all, a pleasant day thanks to lower RH values.
SHORT TERM /TONIGHT THROUGH TUESDAY/... Ridging will amplify toward more of a summer-like pattern on Monday in response to a deep trough carving out over the Rockies. The digging of this trough across central CONUS, will push high pressure ewd, situating the region within a modest warm, moist sly flow regime. As shortwave support increases with the approach of the trough, precipitation chances will increase, mainly for east-central Ohio.
By Tuesday, the risk for showers will increase as an impressive cold front barrels through the upper Midwest.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... The cold front will swing through the region on Wednesday. Expect widespread steady rain throughout the day, with a line of thunderstorms possible with FROPA.
Cooler, generally drier air will filter in behind the front, with a few showers lingering closer to Lake Erie and in the higher terrain via upslope through Thursday as deepening low pressure centered over the Great Lakes becomes negatively tilted. High pressure will finally promote dry conditions by Friday, with continued seasonable temperature.
