(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kiln 191956 afdiln area forecast discussion national weather service wilmington oh 356 pm edt Mon aug 19 2019 Synopsis A mid level disturbance will bring another chance of thunderstorms on Tuesday. A cold front will approach from the northwest on Wednesday and slowly move through the region Wednesday night and Thursday. This will bring cooler and less humid conditions for the end of the week. Near term until 6 am Tuesday morning Weak boundary extending across northern counties has provided enough focus for some thunderstorms to develop. Expect to continue to see activity near this boundary for the next several hours and then diminish by early evening. It is not out of the question that isolated storms could also develop late this afternoon into northern kentucky counties off of outflow from storms further south. There are some indications that a few showers or thunderstorms could develop during the overnight hours. Confidence in that occurrence is quite low so have not included pops for that potential, but it is something to monitor. Short term 6 am Tuesday morning through Tuesday night Guidance is in good agreement in developing a convective system in iowa and moving it southeast through the day. The signal for what occurs as it approaches the forecast area become more diffuse than points further west. High resolution ensemble is suggesting that the system could turn more south into western parts of kentucky. However, scattered to numerous storms are still expected to develop across the forecast area during the afternoon and continue into the evening. These storms will occur in a very unstable environment and thus have the potential to produce damaging winds and perhaps some large hail. Highs and lows are forecast to be near persistence. Long term Wednesday through Monday Long-range models continue to show a slightly slower progression of a cold front through the region midweek than has been shown over the past several days, courtesy of midlevel energy ejecting east- southeast from the mid-missouri valley east into the southwestern ohio valley which will act to slow the southward progression by Wednesday night into Thursday. With the S W energy interacting with the quasi-stationary surface front draped e-w across the southern ohio valley by Thursday, have increased pops and nudged them a bit |
further to the north during the afternoon and evening. While there are subtle differences between the longer-range solutions regarding the timing of the front finally pushing a bit further south, models have come into marginally better agreement showing precipitation lingering mainly near south of the ohio river early Friday before drier and cooler air settles in area-wide for Friday afternoon through the end of the long term period. This will also signal an end to the warm and humid airmass that had remained anchored over the region for quite some time. Confidence remains high in an extended dry period evolving for the upcoming weekend as the mid-upper level troughing digs into the northeastern u.S. And surface high pressure settles into the great lakes and interior northeast u.S. Temperatures will be slightly below normal both Saturday and Sunday, with the best chances for isolated diurnally-driven shower storm activity pushed well to the south of the iln fa. In fact, lows will likely drop into the 50s for many spots on both Saturday and Sunday morning. Aviation 20z Monday through Saturday Vfr conditions will continue through the first half of the taf period. Cumulus at the beginning of the period will decrease by 00z but perhaps not completely diminish. Sufficient low level moisture with weak flow will result in some visibility restrictions late tonight. At this point have only taken kluk to ifr. Visibility will improve after 12z with cumulus increasing again late in the TAF period. Outlook... Thunderstorms possible at times from Tuesday through Thursday. Iln watches warnings advisories Oh... None. Ky... None. In... None. Synopsis... near term... short term... long term... Kc aviation... |

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. |
