681 FXUS63 KIWX 181901 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 201 PM EST Tue Nov 18 2025 .KEY MESSAGES... - Rain showers and perhaps a bit of drizzle coming to an end late tonight mainly after Midnight EST. - Cloudy to mostly cloudy conditions expected over the next several days. - Another system passes south of the forecast area beginning Thursday through Saturday afternoon bringing increased chances of rain showers. At this time precipitation totals look to again be on the light side with the system pushing further south in recent model runs. - Seasonable temperatures expected through the weekend into the beginning of next week. && .DISCUSSION... Issued at 130 PM EST Tue Nov 18 2025 Today`s disturbance will continue to move eastward tonight bringing an end to the light rain showers and possibly a bit of drizzle especially south of US-30 by early morning Wednesday with some drier air pushing southward into the area this evening. However, with a more zonal flow in the wake of this system cloudy to mostly cloudy conditions should continue over the next several days. This will also keep high temperatures pretty stable and seasonable through the beginning of next week with highs in the upper 40s to mid 50s. Another system originating from Baja of California will move northeastward across Texas into the Ohio River Valley. This will increase chances of rain showers for our area beginning Thursday afternoon into There is a bit uncertainty to the exact track of the system but latest guidance does bring it south of our CWA. This would help to keep precipitation in the liquid form and limit the rainfall amounts. So will need to keep an eye on the exact track as the further south it goes the less rainfall we would see. Looking well ahead for late next week there are indications of a much colder airmass to move into the area for the holiday. This may include some snowfall however with more than a week away will need to continue to monitor for that potential in the coming days. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1256 PM EST Tue Nov 18 2025 Surface low pressure across MO this aftn will push east through the lower OH valley overnight as high pressure settles into the gtlks region by sunrise Wednesday. A warm front ahead of the low pressure system is situ south of the fcst area. The latest radar trends have shown an area of rain showers clipping the KFWA terminal with vsbys dropping at times to MVFR. The fcst sounding for KFWA shows a rather strong inversion through the night so low cigs are anticipated there while KSBN should not be impacted as much with regard to persistent low cigs. The rain should be east of the area by 06Z. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None. MARINE...None. && $$ DISCUSSION...Andersen AVIATION...Frazier
