NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 13, 2:59 PM EST, 2 hours 8 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 359 PM EDT Sat May 13 2023 .SYNOPSIS... High pressure will start to build into the area tonight and persist through the early part of the week. A dry cold front will pass on Tuesday night followed by another high pressure system. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Cold front has progressed into southeast Indiana stretching eastward to near Portsmouth. This front will continue southward with scattered to numerous showers near it. Still expect to get some thunderstorms with this activity. This will all clear the forecast area early this evening. There is the potential for an MCS to occur well south and west of the forecast area tonight with the northern edge possibly grazing areas from Ripley County into Owen County. Otherwise, there will be a good deal of mid and high clouds, although there may be a period of clearing in southern counties this evening. Lows will be in the mid 50s to lower 60s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... Surface ridging will keep the area dry on Sunday although mid and high level moisture will be prevalent. A short wave will drop southeast out of the Great Lakes Sunday night. It is not completely out of the question that there is enough lift with this to generate elevated showers that could be robust enough to saturate the dry low levels. But most guidance continues to keep the region dry. So have only gone with low chance PoPs. Expect a respectable gradient in temperatures with highs on Sunday ranging from the upper 60s to around 80s with lows Sunday night in the mid 40s to mid 50s. && .LONG TERM /MONDAY THROUGH SATURDAY/... Temperatures just under normal start the forecast period. From Thursday onward, readings should be at or slightly above normal. Shortwave energy over southwestern CWA on Monday should be weakening/exiting as a weak surface high pressure builds to the north and northeast. Tuesday will see a dry cold frontal passage and the highest uncertainty in the forecast will occur Wednesday. Ensembles are diluting the possibility of colder air winning out on Wednesday and overnight. Feel that NBM is too warm and will be adjusting downward with future runs. Strong high pressure to the north then tracks southeast and keeps a dry airmass over the region through Thursday. Chances of showers increase ahead of a cold front later Thursday and peak Friday with the frontal passage. While showers in the wake of the front and cold air intrusion are possible, expect the period beyond Friday night to be dry. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... Showers and possibly some thunderstorms will be in the vicinity of the Cincinnati terminals for the first several hours of the TAF period. Outside of this, there have been breaks in the lower clouds, but still sufficient low level moisture for MVFR ceilings to occur. Expect these lower clouds to scatter and/or lift before 00Z. Thereafter will only see mid to high clouds through the remainder of the period. There will likely be some visibility restrictions in mist/fog at KLUK tonight and cannot rule that out at KILN either. Winds will generally be northeast at 10 kt or less. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS... NEAR TERM...
