586 FXUS63 KIWX 110533 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 133 AM EDT Thu Jul 11 2024 .KEY MESSAGES... - Fog possible late tonight into the start of Thursday morning. - Turning warm and humid with daily isolated to scattered afternoon showers and thunderstorms. Near 90 degree temperatures expected this weekend into early next week. && .UPDATE... Issued at 724 PM EDT Wed Jul 10 2024 Skies will continue to clear, with NE areas possibly taking the longest to clear out as the remnants of Beryl continue to shift east. With clear skies, diminishing winds and a very moist boundary layer (especially along and west of I-69) think some ground fog concerns may sneak in overnight. Still finalizing things with surrounding offices, but for now will likely have at least patchy fog for most to maybe all of the area with consideration for areas of fog for the NW half or so of the area (roughly Monticello to Warsaw to Coldwater) where the heaviest rain fell and greatest chance for clear skies and light winds exists. && .DISCUSSION... Issued at 130 PM EDT Wed Jul 10 2024 Wrn flank of remnant Beryl circulation is on the way out with rapidly diminishing light rain expected across nrn/cntrl zones. Clearing along with insolation drive destabilization over far swrn zones could pop a few isolated showers and/or storms prior to sunset within residual low level moisture plume however cam guidance firmly holds this wwd across IL and will follow suit. Drying continues short term Thursday as Beryl lifts out however residual upstream mid level trough may yield a few showers and/or storms far sw zones again Thu aftn pending degree of leftover moisture present within destabilizing airmass. Thereafter some degree of mid level trough persists across the Great Lakes Fri on with daily insolation driven chances for additional showers and storms. Difficult to discern a particular feature within innocuous looking flow aloft to latch onto and will keep with broad brushed, afternoon centered pops days 3-7. Otherwise building thermal ridge into and through the wrn OH valley in time will make for a return to warm and humid conditions by this weekend and extending into the middle of next week before a more meaningful cool down associated with cold frontal passage occurs towards day 9 (Thu). && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 133 AM EDT Thu Jul 11 2024 Primary aviation concern is potential for fog later this morning given mostly clear skies, calm winds, and residual surface moisture. Latest concensus guidance (supported by area obs) shows a lot of variability and not expecting widespread/dense fog. KSBN still looks to have the better chance with brief IFR possible. Chances are much lower at KFWA but introduced a TEMPO 5SM. Otherwise there is a very low risk for isolated storms Thursday evening but confidence in coverage and timing is far too low to mention in the TAF`s. Winds will remain light and variable through the period. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None. MARINE...None. && $$ UPDATE...Fisher DISCUSSION...T AVIATION...AGD
