(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kiln 231052 afdiln area forecast discussion national weather service wilmington oh 652 am edt Fri aug 23 2019 Synopsis A cold front will usher in drier and cooler air to the region today as high pressure gradually builds into the great lakes region by tonight into Saturday. Moisture will make a return northward into the area late Sunday and into Monday as a digging system across the mid-missouri valley helps usher in warmer and more humid conditions for the start of the next workweek. Near term until 6 pm this evening Subtle low level convergence coupled with a strung-out midlevel disturbance progressing east through the region has allowed for widespread showers to form this morning -- mainly near and south of the i-71 corridor. Have added categorical pops to account for recent radar trends. And with sufficient forcing amidst a fairly saturated low level environment, shower coverage across the southern southeastern third of the iln fa will be maintained or even increase through sunrise as the much anticipated cold front slowly sags south -- helping gradually shunt the most widespread pcpn further and further south through the early mid morning hours. Anticipate that most if not all of the showers will be south of the ohio river by the noontime hour, with lingering pcpn across perhaps lewis and robertson counties in ky through mid- afternoon before drier air finally moves in for the remaining portions of the local area. But before we can arrive at drier conditions, the aforementioned showers may yield between one quarter and one half of an inch of rain from parts of ripley county, in through hocking county, oh and points south through about noon. The best chance for closer to half of an inch of rain will likely be along and just south of the ohio river from near gallatin county, ky to perhaps scioto county, ohio. These areas will also be the last to clear out this afternoon -- meaning that highs initially will be held in check near the ohio river through at least the first part of the afternoon. The clearing line will drift south through midday, so even southern spots may see a late afternoon jump in temps before diurnal cooling begins toward sunset this evening. And with this in mind, think that the warmest temps for this afternoon will fall perhaps across the center part of the cwa (in spots that will clear out quicker but not have the cooler air filtering in quite yet). Highs in the mid 70s are expected north of i-70 and in parts of northern ky while temps will top out in the upper 70s to near 80 degrees in southeastern in, southwestern ohio through southern parts of central oh. Short term 6 pm this evening through 6 pm Saturday High pressure will build into the great lakes region tonight into Saturday, providing abundant sunshine, low humidity, and seasonably mild temperatures. Lows tonight will drop into the lower to upper 50s from north to south. Many spots have not seen such temperatures since mid-june. Meanwhile highs will rebound to the mid upper 70s on Saturday. Better moisture return ahead of the next system will hold off until after the conclusion of the short term period. Long term Saturday night through Thursday High pressure centered over the northeast united states Saturday |
night will continue to shift off to the east through the day on Sunday. This will allow for some return flow to begin to set up across the mid ohio valley through the day on Sunday and into Sunday night. Temperatures will begin to rebound a bit through the day on Sunday with afternoon highs in the upper 70s to lower 80s. We will start to see an increase in moisture in developing low level southerly southwesterly flow Sunday night and Monday. Meanwhile, ridging aloft will also begin to break down through Sunday night as mid level energy embedded in a broader mid upper level trough shifts east across the mid mississippi valley and into the great lakes region Monday through Tuesday. This will lead to an increasing chance of showers and thunderstorms, initially across our west later Sunday night and then across our entire area Monday into Monday night. The trough axis will shift off to the east Tuesday into Tuesday night, leading to a decreasing chance of showers. High pressure and a drier airmass will settle across the region Wednesday into Thursday. High temperatures will generally remain in the upper 70s to lower 80s through the remainder of the long term period. Aviation 12z Friday through Tuesday A corridor of scattered showers stretching from southeastern in through south-central oh will continue to slowly shift southeast through the first several hours of the period. Some brief MVFR vsbys associated with a heavier shra cannot be completely ruled out at kcvg and kluk through the first hour or so of the period, but expect a trend toward generally drier conditions past about 14z at even southern sites. Numerous individual cloud decks are present across the immediate area as of 12z, with the lowest CIGS coincident with the heaviest shra activity. Nevertheless, the mix of 1000ft and 2000ft CIGS currently meandering about kcvg and kluk will gradually trend towardVFR past about 15z as the better low level moisture gets shunted south east. SctVFR clouds will persist through the heart of the afternoon hours -- particularly for kcvg, kluk, and kiln before clearer skies evolve towards early evening. And other than a few passing cirrus, skc is expected for all terminals tonight through early Saturday morning. Northeast winds of about 10kts this afternoon will gradually subside past sunset this evening. While the gradient will not relax completely, could see some MVFR vsbys towards sunrise Saturday at vulnerable locations (area river valleys) including kluk. Outlook...

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. |
