Area forecast discussion, Jun 29, 4:21 PM EDT, 2 hours 39 minutes before
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 421 PM EDT Tue Jun 29 2021 .SYNOPSIS... Warm and muggy conditions with scattered storms continue through the evening under the western periphery of subtropical high pressure centered off the United States east coast. The coverage of showers and storms increases Wednesday and Thursday with a slow-moving frontal system before cooler -- and a bit drier -- weather returns late in the week. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Weak southwesterly flow to continue through the near term on the backside of subtropical high pressure to the east. A mid-level trough will slowly dig south into the upper Midwest late tonight with height falls by morning. Scattered diurnal convection this evening will slowly decrease in coverage after sunset. Low temperatures will stay in the low 70s. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... Heights slowly fall through the day on Wednesday as a weak frontal boundary sags south into lower Michigan. With cooling aloft accompanied by weakly convergent low-level flow, expect showers and storms to increase in coverage by late morning and continue through the afternoon. Increasing clouds will likely limit instability to some degree, though shear increases a bit to the 20-25 knot range by afternoon. Feel this combination supports HWO mention of potential for a few storms containing strong to damaging wind gusts. Highs on Wednesday peak in the low to mid 80s by afternoon. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Positively tilted mid level trof to drop south through the Great Lakes Thursday with surface cold front dropping south through the Ohio Valley Friday. Have categorical pops across the south and central counties with the potential for heavy rainfall into Thursday evening with precipitable water values approaching 2 inches. Model solutions continue to show this system to be progressive, so any flood threat looks minimal at this point. Temperatures a little cooler with highs in the upper 70s to around 80 Thursday. Additional mid level energy to drop into the trof with a closed low developing over Eastern Ohio/Western PA late Friday/Saturday. This will keep low chance pops for diurnally driven showers and embedded thunderstorms on both days. The best pops will occur across the east closer to the mid level low and cooler temperatures aloft. Cooler temperatures will continue with highs Friday and Saturday in the mid and upper 70s. This system will push east on Sunday with a slight chance of pcpn coming to an end. Temperatures look to moderate slightly with highs around 80 Sunday. A weak shortwave spilling south around the periphery of a ridge building into the area may lead to a few showers over the northeast Monday. Confidence on this feature and associated pcpn is low. Warming trend to continue with highs on Monday in the mid 80s. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... VFR conditions to remain through the TAF period with showers and storms being the main impact to aviation. Scattered coverage this evening increases Wednesday with the approach of a weakening cold front. Light southerly winds will continue outside of storms. .OUTLOOK...Thunderstorms possible through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS...Hogue NEAR TERM...Hogue SHORT TERM...Hogue LONG TERM...AR AVIATION...Hogue
