957 FXUS63 KIWX 112316 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 716 PM EDT Sat Oct 11 2025 .KEY MESSAGES... - Much of the next week will feature near to slightly above normal temperatures. - Monday and Tuesday will be the warmest days with highs in the low to mid 70s. A cold front will come through on Tuesday, bringing more seasonable temperatures back into the 60s by midweek. - Drought persists this week as dry conditions continue. Low chances (10-30%) for rain return on Friday and Saturday. && .DISCUSSION... Issued at 217 PM EDT Sat Oct 11 2025 Unfortunately, the highest rainfall amount observed yesterday was 0.03" in our far northwest CWA. As dry conditions continue through the upcoming week, the ongoing drought is expected to persist and potentially worsen (especially in areas that are already in Severe to Extreme Drought). As of right now, Fort Wayne and South Bend are on track to be in the Top 10 driest Octobers on record in 125+ years. An amplified upper level ridge over the central US will expand over the Great Lakes region in the coming days, which will allow for moderate WAA into early next week. Highs near 70 are on tap for Sunday, with slightly warmer temperatures with highs in the low to mid 70s on Monday. The ridge flattens on Tuesday, allowing for a cold front will sweep through. The cold front will limit diurnal heating in the northwest; Highs near Lake Michigan will be in the 60s while areas along and south of the US 24 corridor will approach the mid 70s before the front comes through. More seasonable air arrives mid to late week with highs in the 60s area-wide. A few showers could be possible with Tuesday`s front, although better chances (albeit still low) for rain could arrive next Friday and Saturday. Long range model guidance still has lots of discrepancies this far out as to how much moisture will be available or if a system even develops at all. This will be something to monitor in the coming days but for now, it appears as though no significant rainfall is expected in the next 5 to 7 days. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 715 PM EDT Sat Oct 11 2025 A slow moving upper level low across the eastern Great Lakes will slowly sag southward and weaken over the next 24 hours. This will help dissipate an inverted trough type feature across the eastern Great Lakes and allow for a more veered easterly low level flow to take shape. A stratocu deck persists early this evening from IN/MI stateline to much of southern Lower Michigan where cigs have been reported in the 3-4k ft range. The veering of the low level flow should keep bulk of stratocu north of KSBN this evening. Some patchy stratocu may work in from eastern Great Lakes into northeast Indiana overnight, but bases of these clouds should be VFR. Cannot rule out some patchy shallow fog early Sunday AM, but would expect greater chances across south central Lower MI. VFR conditions continue Sunday, with east-southeast flow generally 10 knots or less && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
