030 FXUS63 KIWX 111846 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 146 PM EST Tue Nov 11 2025 .KEY MESSAGES... - Slick spots possible ovrnight and for the Wednesday morning commute, especially on secondary roads. - The rest of the week will be dry with warming temperatures. - Next chance for rain arrives Saturday night into Sunday. && .DISCUSSION... Issued at 146 PM EST Tue Nov 11 2025 Scattered snow flurries are moving through the area today, with little to no accumulation expected. Though not as cold as the past two nights, overnight lows will drop to near or just below freezing. Melting snow this afternoon/evening could result in some slick spots overnight and Wednesday morning as it refreezes overnight. After a very active past few days, the upcoming next several days will be mainly quiet, dry, and gradually warmer. A tightening pressure gradient between high pressure centered over the Southeast US and low pressure over western Ontario will make for breezy conditions this evening through the day on Wednesday. During the day Wednesday, west winds will be sustained around 15 to 20 MPH with potential for gusts up to 30 MPH. West/southwest winds and increasing WAA through the week will allow for temperatures to moderate back towards seasonable levels by the end of the work week. Tomorrow high`s will be in the mid to upper 40s and by the weekend, highs are anticipated to be in the 60s! A low pressure system will lift through the Upper Midwest into Ontario on Saturday. It`s attendant warm front may bring scattered rain showers during the day Saturday (low chances), but better chances for rain arrive Saturday night into the day Sunday with the system`s attendant cold front. As this is 4-5 days out, there is still a lot of uncertainty to work through regarding the overall timing and rainfall amounts. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1224 PM EST Tue Nov 11 2025 Mid level height falls tonight overtake today`s height rises indicating less suppression around for systems as a shortwave passes through Lake MI and WAA transitions to CAA. With this influence, the RAP and the NAM both have some low to mid level moisture that approach MVFR conditions. This is not reflected in GLAMP/LAV/CONShort guidance, which sees it as mid-high level CIGs. Am inclined to hold onto the latter guidance until greater confidence arises, but even the HREF indicates some higher probabilities of MVFR conditions overnight. With the passage of that wave, a 50 kt jet moves through this afternoon and a 40 kt NW`erly jet overtakes it overnight. This allows for the possibility of LLWS at both sites. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
