AREA FORECAST DISCUSSION National Weather Service Wilmington OH 624 AM EDT Sun Aug 9 2020

SYNOPSIS. Surface high pressure will move off to the east through tonight. A frontal boundary will sag down into the Ohio Valley through mid week as a series of upper level disturbances move east across the region. This will lead to a chance of mainly afternoon and evening thunderstorms through much of the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Weak mid level ridging will move east across the area through this afternoon as surface high pressure continues to shift off to the southeast through the day. Dewpoints will gradually increase from the west through the day, leading to some moderate instability just off to our west/northwest through the afternoon. However, the air mass across our area will remain relatively dry through the column and this should help keep any pcpn off to our west through the afternoon. Highs today will be in the upper 80s to around 90 degrees.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. Zonal flow tonight into Monday will allow for some mid level energy to push east across the region as a cold front sags southeast across the western Great Lakes. Instability off to our west will gradually weaken through tonight and high res models are hinting at the possibility of some weakening showers and thunderstorms pushing east/southeast toward our area late tonight into early Monday morning. Not sure how much if any of this will make it into our area so will generally just bring some lower end pops into the west late tonight. There remains some uncertainty as to how much redevelopment we will see then through the afternoon on Monday as we start to destabilize again. Although the CAMs are not showing too much in the way of development, will at least bring some chance pops into the west through the afternoon given the approach of the next wave of mid level energy. Highs on Monday will be in the upper 80s to lower 90s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. An unsettled weather pattern will be in place through the long term time frame with daily thunderstorm chances. One impulse will be working through at the start of the long term Monday night. There is some decent instability with this system. Cannot rule out a strong to severe storm. Another disturbance will work through during the overnight hours and into the daytime on Tuesday. This will bring additional showers and thunderstorms to the region.

This trend continues Wednesday through Sunday as several additional disturbances push through the area. There is a little less in the way of instability later in the week.

High temperatures through the week will generally in the 80s and low temperatures in the 60s to around 70 degrees.

AVIATION /10Z SUNDAY THROUGH THURSDAY/. Areas of mainly river valley fog will burn off through mid morning. Otherwise, surface high pressure will continue to push off to the southeast through the day with some scattered afternoon cu possible. Any cu should dissipate toward sunset leaving mostly clear skies heading into tonight. A weakening upper level disturbance will approach from the west late tonight. A few showers or thunderstorms associated with this may reach the western TAF sites toward the tail end of the TAF period, but the chance looks low enough to leave any mention out of the TAFs at this point.

OUTLOOK . Thunderstorms are possible on Monday through Thursday, mainly in the afternoon and evening.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
