Area forecast discussion, Aug 2, 2:41 PM CDT, 1 hour 51 minutes before
Area Forecast Discussion National Weather Service Northern Indiana 341 PM EDT Thu Aug 2 2018 .SYNOPSIS... Issued at 309 PM EDT Thu Aug 2 2018 Scattered storms are likely over far southwest Lower Michigan into northern Indiana through this evening ahead of a weak cold front. All of the activity will dissipate before midnight. Conditions will then be mainly dry through the weekend with highs warming well into the 80s. && .SHORT TERM...(This Evening through Friday) Issued at 300 PM EDT Thu Aug 2 2018 A weak cold front will approach the area early tonight from the northwest. It looks like there will be a narrow window for storms late this afternoon into this evening. Some of the convective allowing models show some hints of marginally severe storms during this time. However, mid level lapse rate around 5.5C/Km and some apparent weak subsidence over the area have been really stifling storms upstream. Current thinking is storms are still possible from basically 5 pm to 9 pm EDT. Slightly cooler weather will follow for Friday. An isolated storm is possible along/ahead of the front over mainly northwest Ohio Friday afternoon. Severe storms are not expected Friday. && .LONG TERM...(Friday Night through Thursday) Issued at 300 PM EDT Thu Aug 2 2018 Conditions are expected to be dry this weekend with highs well into the 80s as an upper level ridge attempts to build into the area. After that, there is a good chance for showers and storms from Monday into Tuesday as an upper level trof develops into the region. Organized convection is likely at some point during this time given the upper level support. Precipitable water values should top 2.0 inches, bringing the potential for locally heavy rainfall. && .AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon) Issued at 122 PM EDT Thu Aug 2 2018 Flight conditions will remain VFR for the forecast period. Thunderstorms will develop this afternoon near KSBN ahead of the approaching cold front. Storms weaken after sunset and will no reach into FWA. Gusty winds out of the sw this afternoon will diminish overnight. Hires guidance suggests a chance some low stratus overnight but left out to low confidence in winds becoming calm overnight. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
