000 FXUS63 KIWX 242304 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 705 PM EDT Thu May 24 2018 .SYNOPSIS... Issued at 239 PM EDT Thu May 24 2018 High pressure will continue to provide fair weather conditions into tonight and Friday. Lows tonight will range between the mid 50s and low 60s, with highs on Friday into mid to upper 80s. Temperatures and humidity will be on the increase in time for the holiday weekend. Highs each day will range between the mid 80s and low 90s. There is a low chance for showers and thunderstorms Friday night into Saturday. Mainly dry conditions are expected otherwise into early next week. && .SHORT TERM...(This Evening through Friday) Issued at 239 PM EDT Thu May 24 2018 Stable/dry airmass on the western fringe of a low level ridge axis will ensure more fair wx into tonight and Friday. Temperatures will continue to trend warmer as sfc winds veer more southwesterly on Friday. && .LONG TERM...(Friday Night through Thursday) Issued at 239 PM EDT Thu May 24 2018 The holiday weekend will feature unseasonably humid/hot temps and low chances for storms mainly Saturday... A mid level trough and associated 30-40 meter height falls at 500 mb will work east through the region Friday night into Saturday. This feature will fold higher theta-e air and a subtle sfc trough in bringing clouds and chances for showers/storms back into the forecast during this time. Overall weak deep layer forcing/flow continues to support low PoPs (generally 20-30%) during this time...best chances Saturday afternoon along/east of I-69 tied to diurnal/heating cycle. Sunday and Monday should feature dry/hot conditions as upper ridging becomes re-established over the Great Lakes region. Northern stream westerlies will then finally ingest deeper moisture (from a Deep South upper low) north by mid-week bringing renewed shower/storm chances Wed-Thu. && .AVIATION...
