828 FXUS63 KIWX 111725 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 1225 PM EST Tue Nov 11 2025 .KEY MESSAGES... - There is a chance for flurries today but no accumulation or impacts are expected. - Otherwise dry conditions persist through Friday with slowly warming temperatures. - Temperatures return to the 60s over the weekend with a chance for rain. && .DISCUSSION... Issued at 312 AM EST Tue Nov 11 2025 Low level winds have now fully backed westerly, reducing fetch with crashing inversion heights and increasing dry air entrainment. Lake effect band is rapidly weakening and shifting east as a result. Snowfall reports have been scarce overnight but reports thus far substantiate forecast of 3-6" in our NW counties. Snow has ended in the western tier of counties for several hours now and eastern areas likely received less overall snow. With snow band now exiting, will go ahead and cancel the advisory by 4am. A pair of shortwaves will ripple through the region today and tonight. The first will send a weak warm front through the area. Some minor isentropic ascent could support flurries at times today but overall profile is very dry and stable with limited mid/upper level support for ascent. Do not anticipate any accumulation or impacts. Highs climb into the mid/upper 30s today and don`t drop much tonight with the passing warm front. When the second wave passes to our NE late tonight, temps will actually be warm enough for just rain. Here again though precip chances are severely limited by poor forcing and residual dry air. Maintained slight chance in our far NE but most locations will remain dry. Quiet weather is expected the rest of the week with slowly moderating temperatures. Another warm front will lift through the region Friday night/Saturday and this could touch off a few isolated, light showers. Better chances for rain occur with the associated cold frontal passage later Sunday into Monday but models still show a very large spread with evolving pattern early next week and confidence in details is very low. Do still expect a period of 60s over the weekend though. && .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. MARINE...Small Craft Advisory until 10 AM EST Thursday for LMZ043-046. && $$ DISCUSSION...AGD AVIATION...Roller
