352 FXUS63 KIWX 311833 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 233 PM EDT Thu Oct 31 2024 .KEY MESSAGES... - Windy this afternoon and evening with a few gusts to 40 mph possible. - Next chance for showers and an isolated storm late Sunday. && .DISCUSSION... Issued at 231 PM EDT Thu Oct 31 2024 Intense upper low bringing snow to parts of MN will accelerate out into sern ON tonight as cold front surges ewd. Broad but decaying area of light rain overhead in association with prefrontal trough will fizzle ewd into wrn OH while narrow, broken cold frontal rainband pivots across the area this aftn with gusty sw winds behind the front for this evening. Cool and dry through Sat ahead of next sys deepening invof the srn Rockies. This sys ejects out into the plains late Mon and then shears newd into the nrn lakes late Tue, track similar to last several systems. Rapid uptick in warm advection in tandem with leading return moisture should foster shower development by Sun aftn far west yet no slam dunk as wrn flank of persistent ridge is slow to retreat esp given upper sys track well nw of the area. Will make some amends to overtly generous pop blended guidance early Sun into early Mon as warm sector becomes established across the OH valley with highs back into the 70s Mon. Thereafter weakening and poorly timed cold front washes east Tue with some lingering showers. Rest of the period through into next weekend dry, cool and quiet as broad high pressure ridges in across the Great Lakes and wrn OH valley. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1224 PM EDT Thu Oct 31 2024 Times of VFR light showers/sprinkles will persist pre-frontal to start as moisture continues to advect in. Cold front is still on target to swing through KSBN around 20z, and KFWA around 22z. A thin line of more robust showers (brief vis restrictions) may accompany this frontal passage with gusty winds to 35 knots possible. Skies may briefly clear out behind the front into this evening. However, cooler wnw over the warmer lakes will likely allow MVFR stratus to drop into the terminals overnight into Friday morning. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None.
