AREA FORECAST DISCUSSION National Weather Service Charleston WV 238 PM EDT Sun Aug 29 2021 .SYNOPSIS... Hot and humid conditions prevail with daily afternoon thunderstorm chances through Tuesday. Remnants of Ida arrive Tuesday night into Wednesday with heavy rain. && .NEAR TERM /THROUGH MONDAY/... As of 100 PM Sunday... A weak upper level disturbance has created a bunch of showers and thunderstorms early this afternoon over northeastern Kentucky and southeastern Ohio. With plenty of instability over the area this afternoon, have increased chances of precipitation in most areas, especially near this disturbance. Models vary over how long showers and thunderstorms will last tonight and if addition precipitation will form late tonight. Due to differences between the models, have kept POPs fairly generic, with better chances in the north. Moisture remains over the area on Monday as a cold front approaches from the north. With plenty on instability over the area and another weak upper level disturbance, expect numerous showers and thunderstorms with the best chances across the north closer to the cold front. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 215 PM Sunday... For Monday night, expect rain chances to spread across the area with likely shower activity for the northern half of the CWA. This will be a result from a frontal boundary draped west to east just north of the area. This boundary should stay north as Tropical Cyclone Ida approaches from our south which will likely keep the boundary stationary to the north as Ida pushes a warm frontal north through the CWA. If for some reason the frontal boundary moves south as Ida slides through this northerly flow perpendicular to the frontal boundary with a modest low level jet of at least 40KT, plus a deepening upper level trough and isentropic ascent will set up a Maddox Frontal event which will promote even more of a flooding potential with flash flooding. This will have to be carefully looked at for a decision on a widespread flood watch issuance in the next shift or two. Most models/ensembles keep the eye tracking just south of our center which will keep the higher rainfall amounts in the northern parts of the area while they get hit the hardest in the northeastern sector and wrap around flow of Ida where the heavier rain usually occurs. Steady light rain should become apparent by Tuesday morning/afternoon and continue into Wednesday The main threat will be flooding with maybe some gusty strong wind within any convection that may occur. This possible wind threat from convection could potentially take down some trees, especially with the help of heavier rain/showers. Also, we cannot rule out a weak tornado within any convection particularly in the northeastern sector of Ida or within any convection associated in heavy rain banding. By midday Tuesday, Ida will have moved in and rainfall rates will have moved up in intensity dropping 3 to 4 inches (total) going into Wednesday with localized higher amounts of 4-5+. Continuous light to moderate rainfall or heavier showers in convection will likely fall and stick around until Wednesday evening at which point Ida will make a move and exit to the east-northeast. Temperatures will take a tumble and fall well below seasonable for a nice cool down associated with Ida's visit. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 215 PM Sunday... Overnight Wednesday into Thursday morning, remnants of Ida will be traversing toward the east leaving very little in the way of any chances for rain the rest of Thursday. Any activity that may come to fruition would be mainly confined to the mountains, if any. Temperatures will continue to fall well below seasonable into the weekend with a high pressure system from the midwest building in and hopefully shielding the area from any unsettled weather into the weekend. Temperatures will try and rebound from Ida rising to right around seasonable by Saturday. As heights flatten and high pressure weakens some slight chances for a diurnal shower or storm will be possible for maybe Saturday afternoon and more likely on Sunday afternoon. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 100 PM Sunday... VFR cumulus can be expected this afternoon, with scattered showers and thunderstorms causing brief IFR restrictions. While showers and thunderstorms will become less numerous this evening, a few could continue overnight and into Monday morning. Fog can be expected tonight in areas that receive rainfall today. A cumulus deck can be expected again Monday morning. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: Medium.
