Area forecast discussion, May 24, 3:38 PM EDT, 1 hour 29 minutes before
Area Forecast Discussion National Weather Service Wilmington OH 338 PM EDT Wed May 24 2017 .SYNOPSIS... An unsettled pattern will be present across the region through the week. An area of low pressure will meander across the region through Thursday. Multiple systems will then work across the area Friday through Tuesday. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... An area of low pressure will move into the region this evening. Showers and some thunderstorms will rotate around this feature. Precipitation may be heavy at times. With low LCLs cannot rule out some tornado potential through the early evening hours. Will continue to mention the severe threat in the HWO and added additional flash flood risk wording across western portions of the region. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... Showers and isolated thunderstorms will continue to be possible on Thursday as an area of low pressure meanders across the region. With the cloud cover associated with the low, temperatures will struggle to rise and are only expected to make it into the middle 60s. As the low moves off out of the area precipitation chances will taper off Thursday night. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Mid level ridging will push east across the region through the day on Friday leading to dry conditions and seasonable temperatures. As the ridge pushes east, a developing southwesterly flow pattern will allow for occasional mid level short waves to cross the area through the weekend. This will result in a chance of showers an thunderstorms Saturday and Sunday with highs both days in the upper 70s. An upper level low will slowly drop down across the northern Great Lakes through early next week. As it does, some weak energy will rotate around it, bringing some lower chances of precipitation through the rest of the long term period. Temperatures will also cool off a bit with highs mainly in the low to mid 70s through Wednesday. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... An area of low pressure will meander across the area through the TAF period. This will allow for reduced visibilities with intermittent showers and thunderstorms. The most widespread coverage of precipitation is expected to be across KCVG and KLUK. In addition, cigs will be reduced as well especially later during the overnight hours into the daytime hours on Thursday. OUTLOOK...MVFR to IFR ceilings likely Thursday with MVFR visibilities possible. MVFR ceilings, visibilities, along with a chance of thunderstorms possible Friday night into Sunday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS...Novak NEAR TERM...Novak SHORT TERM...Novak LONG TERM...JGL AVIATION...Novak
