NWS Charleston, WV wrote its last area forecast discussion before the first event at Aug 29, 12:12 PM EST, 1 hour 13 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Charleston WV 112 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 TUESDAY/... As of 245 AM Sunday... Monday looks to be slightly cooler as upper level ridging is suppressed by a northern stream trough moving into the lower Great Lakes Sunday night. A combination of cooler temperatures and weaker mid-level lapse rates will yield less surface based instability Monday, but nebulous synoptic ascent grazing our northern counties associated with stronger upper level low moving through the Great Lakes looks to provide a focus for afternoon convection and will maintain scattered coverage advertised by central guidance. With a synoptic assist, this activity will likely continue through the overnight and into Tuesday morning. A slow moving cold front associated with the aforementioned trough approaches Tuesday providing a more dreary and wet day. While rainfall associated with Monday and Tuesday's activity is not expected to be overly impressive, high precipitable water values and slow storm motions could lead to some localized high water issues. This could also set the stage for potentially more significant flooding with runoff from the remnants of Ida if soils can become locally compromised. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... As of 245 AM Sunday... The slow moving cold front and upper trough mentioned in the short term discussion will ultimately play a large role in the eventual track of the remnants of Ida and maximum QPF swath Tuesday night into Wednesday. EPS solutions have generally come a bit more in-line with the more northern GEFS solutions of the last several days that suggest Ida's track will roughly bisect the forecast area from southwest to northeast with the heaviest rainfall axis generally along the Ohio River. Here, basin average rainfall totals of 3 to 5 inches may be realized while farther southeast and northwest totals look to fall into the 1.5 to 3.0 inch range. Rainfall rates will not be quite as impressive (generally <2"/6hr) as with convection of the last few days and currently soils are quite dry outside of recent locally heavy rainfall events. However, these basin average amounts will be sufficient to bring smaller creeks and streams out of their banks and prompt large rises on the mainstem rivers, although at this time the probability for significant mainstem river flooding appears toward the lower end. Unless significant changes are seen over the next day, will likely need either a flood or flash flood watch for at least portions of the forecast area. Will add this threat to the HWO with watches likely forthcoming in the next few forecast cycles. Any lingering heavy rain exits the mountains by early Thursday morning. For the remainder of the work week and into the, high pressure building across the middle Mississippi Valley should keep the region mainly dry under northwesterly flow with temperatures closer to normal values for the beginning of September. && .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.
