797 FXUS63 KIWX 300623 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 222 AM EDT Tue Apr 30 2024 .KEY MESSAGES... - Additional chances for showers and thunderstorms expected Friday. - Unseasonably warm through the week with highs generally in the 70s. && .DISCUSSION... Issued at 222 AM EDT Tue Apr 30 2024 Weak cold front through nw zones will wash ewd through daybreak with post frontal drying yielding pleasant wx into Thu. That said insolation/diurnal heating will bump mixed layer appreciably this aftn and tomorrow aftn with gusty west winds for a time. Rather chaotic and unsettled flow pattern up near the US/Canada border remains with next disturbance and associated jet streak progged to drive east out of the cntrl Rockies early Thu and through the upper midwest early Fri. Robust return flow ahead of this sys slated Thu although maximized west near the MS valley. Warm frontal zone extending ewd into the srn lakes lacking early on but a few showers or storms by late aftn west. Cold front tied to upper wave accelerating into Canada looks to push through Thu night with brief/flat ridging following into early Sat before return flow reemerges ahead of another fast moving wave ejecting a bit further south into the wrn lakes Sat aftn. Nrn track of both systems not ideal with swd dwindling frontal forcing noted which will limit overall rain chances here. More concerted area of high pressure noted through the lakes Sun-Mon. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
