AREA FORECAST DISCUSSION National Weather Service Wilmington OH 351 PM EDT Sun Jun 12 2022 .SYNOPSIS... Weak disturbances moving through an increasingly warm and moist atmosphere will result in periodic chances of showers and thunderstorms through Monday night. Heat will build quickly and Tuesday and Wednesday will see the heat index rise above 100. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... An embedded disturbance will continue to move southeast to the middle Ohio River Valley this evening. Meanwhile, a weak front to our north will settle into the region tonight where it will stall. The combination of these two features will result in the likelihood of showers and storms across the northern/central zones, and a chance of showers and storms over the southern zones. Moderate instability (1000-1500 J/kg MLCAPE) and low end moderate deep effective shear, will continue to pose an isolated severe thunderstorm threat. Gusty to damaging winds are the primary threat. The threat of severe storms should wane later this evening as the disturbance moves away. For the overnight hours, it appears the chance of showers/storms will become more confined to locations along and south of the Ohio River. Lows will range between 65 and 70. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... An anomalous mid level ridge to our southwest will begin to build northeast into the Ohio Valley Monday into Monday night. As this occurs, a warm front will merge with aforementioned stall out boundary, pivoting north/northeast toward the southern Great Lakes Monday night. On Monday, uncertainty abounds in terms of convective evolution and coverage during the day. Some models try to bring an MCV from Missouri into the middle Ohio Valley where it tries to develop into an MCS across parts of Kentucky. Confidence is low, so at this point, a broad brush forecast with chance PoPs associated with the advancing warm front has been employed. Given increasing strong to extreme instability with dewpoints pushing into the lower to mid 70s, along with continued ample deep layered shear, thunderstorms may become severe with damaging winds and large hail. Can not rule out isolated heavy rainfall with pwats around 2 inches. Monday will see the beginning of a period of very hot and humid weather. Have highs ranging from the upper 80s northeast to the lower 90s along and south of the Ohio River. With aforementioned dewpoints, this will result in heat index values between 95 and 100, highest over the south. This is just tickling Head Advisory criteria. Will continue to mention this in the HWO product. As we head into late Monday into Monday night, models still show uncertainty in terms how a convectively enhanced disturbance will propogate from the upper Mississippi River Valley to the Great Lakes. There has been a general trend in the models to move the feature a little bit farther north and east from previous runs. This has been reflected in the latest SPC SWODY2 Outlook, which now has our northern zones (west central Ohio into central Ohio) still under a risk for severe storms. Again, given the strong to extreme instability feeding into this feature, we will have to monitor later model guidance. In fact, some models develop a bowing like structure which would result in a more widespread wind damage threat. Large hail will also be a threat. Lastly, can not rule out isolated tornadoes given veering profiles near the warm frontal boundary. These threats continue in the HWO for the mentioned area. It will be warm and muggy Monday night with lows only in the lower to mid 70s. && .LONG TERM /TUESDAY THROUGH SUNDAY/... H5 ridge becomes well amplified on Tuesday, with the mean axis shifting over the Ohio Valley. The top of the ridge will build far enough northward that no pcpn is expected in our CWA. However, the main storyline will be the combination of hot and humid air that's ushered in from the Gulf under this ridge. Both Tuesday and Wednesday, the combination of surface temps around the mid-90s and dewpoints in the mid-70s will lead to heat indicies likely exceeding 100 degrees during the peak of daytime heating, with some locations observing heat index values exceeding 105. Based on the consistent trends observed from models/ensembles, headlines for heat will likely be issued in the next forecast package or two. Don't see a great chance for pcpn during the day Wednesday, but a few ensembles do show the potential for an isolated pop-up, so went ahead and included a 20% PoP. This will primarily be dependent upon how quickly the H5 ridge breaks down. Come Wednesday night, models show the ridge starting to become more positively tilted and breakdown into Thursday. As this occurs, an upper level trough will begin to sink further south into the upper Midwest region. Latest model runs seem to favor a slightly more progressive breakdown of the ridge with the trough sliding in sooner, thus leading to higher PoPs on Thursday and continuing into Thursday night ahead of a surface cold front. The cold front now begins to enter our fa Thursday night and likely pushes through our remaining southern counties Friday morning. This forecast would thus favor drier weather for the majority of the day on Friday. Behind the cold front, a more pleasant air mass will settle in for the weekend and provide more seasonal temperatures and dry weather. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... Another embedded disturbance in the northwest flow aloft is expected to move southeast across the region later this afternoon into this evening. Meanwhile, a weak front will drop southeast into the northern forecast area. Weak lift associated with both these features, along with increasing moisture/instability, will result in scattered to numerous showers and thunderstorms. Highest coverage is still expected north of the Ohio River, or near the northern terminals. Have placed either VCTS and/or TEMPO TSRA. At least MVFR conditions can be expected with thunderstorms with the potential for lower visibilities (at least IFR) in storms with heavy rainfall. Winds will be from the west/southwest around 10 knots. For tonight, aforementioned disturbance moves southeast while the weak front sags into the area and eventually stalls. Convection should be on a gradual downward trend into terms of coverage. Models suggest that MVFR conditions may develop near and north of the stalled out front. Have included this in the northern terminals. On Monday, a strong mid level ridge to our southwest will begin to build northeast into the Ohio Valley. This process will be associated with a warm front. The warm front and left over weak boundary should make some north to northeast progress through the day. Concern for convection remains uncertain still as various convective allowing models either are dry conditions or show some spotty activity. There is still a concern of a bigger convective complex to affect the area Monday night. Latest model runs suggest that this may stay to our north and east. We will continue to watch and adjust if needed. MVFR conditions in the morning should return to VFR by early afternoon outside of any convection. OUTLOOK...Thunderstorms possible Monday night and then again Thursday into Thursday night. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
