AREA FORECAST DISCUSSION National Weather Service Wilmington OH 411 AM EDT Thu Jul 9 2020
SYNOPSIS. Hot and humid conditions will persist until a weak cold front moves through the region tomorrow. Temperatures will not be quite so warm over the weekend, but the heat builds again towards midweek.
NEAR TERM /UNTIL 6 PM THIS EVENING/. Fairly stagnant pattern for one more day across the forecast area. Weak wind flow and weak forcing will lead to scattered diurnal convection with slightly better coverage probably occurring in the northwest. High moisture content in the atmosphere and deep warm cloud depths will lead to the potential of locally heavy rain, especially with little storm movement.
Temperatures will again be in the lower to mid 90s with dew points near 70. Some places will likely not get to the 100 degree heat index threshold, but nonetheless will continue with the Heat Advisory area wide.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. Showers and thunderstorms will linger into the early evening before dissipating. A short wave will approach the region tonight and move across on Friday. This could bring some showers into western counties late tonight and continue into Friday morning. But better chance of precipitation will hold off until Friday afternoon as a weak cold front moves through. High precipitable water and deep warm cloud depth could lead to some efficient rain, even though storms will be moving more on Friday. Lows will be near persistence. Clouds and precipitation should lead to high being a few degrees lower on Friday compared to today.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. A respite is in store for the extended period, after a cold front passes Friday. Lingering showers and thunderstorms Friday evening will move eastward. A few models continue to keep a threat of a lingering shower on Saturday. Given the unlikely chances, had to cap the precip at 20% after some higher chances early in the morning. Bulk of models remain dry for this period. Saturday night will also be dry with a slight chance of some precip working into the northwest towards daybreak Sunday. Threat of rain Sunday increases as a longwave trough crosses the Ohio Valley. Models have a large discrepancy in how much rain will occur and even moreso on temperatures given the rain should occur through the course of the day. European is quite dry and warmer, while the GFS is profoundly wetter and cooler and continues the cooler temps into next week.
Since trying to determine which model is more credible is folly, even given the similar sensible weather patterns. Resolving temperature differences 10-15 degrees between models on any of the first 3 days of next week is better left at the initialization of the model blend in forecast builder.
If the cooler temperatures in the 80s and lower 80s prevail, it will last through Tuesday, with a return southerly flow expected Wednesday. If the european is correct and the region stays dry with a h5 trough and receptive airmass, the remainder of the forecast keeps a weak southerly flow over the region and hovers highs around 90, then warms back up to the mid or upper 90s from Tuesday onward.
Would think the middle of the road would be for the wet Sunday and cooler temperatures into Monday, returning to what we've been seeing lately by mid week. Propensity for afternoon thunderstorms will not be the norm given an upper ridge overtop of the Ohio Valley Wednesday and return to zonal upper flow beyond that.
AVIATION /08Z THURSDAY THROUGH MONDAY/. There will be few clouds around through the rest of the night. Expect some mist/fog to develop which bring visibility restrictions to a number of the terminals. Conditions are forecast to return to VFR no later than 14Z. Cumulus will develop during the day with scattered showers and thunderstorms about. At this point, the better chance appears to be from KDAY to KCVG/KLUK. Precipitation and then clouds will diminish around 00Z.
OUTLOOK . Thunderstorms are possible Friday through Monday.

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.
