Area Forecast Discussion National Weather Service Northern Indiana 1224 AM EST Sat Nov 7 2026
KEY MESSAGES
- Scattered to numerous lake effect rain showers will continue through tonight, mainly for areas west of Interstate 69 in northern IN and southwest MI.
- Seasonably cool conditions continue into Saturday night before a slow warming trends commences, with highs in the 60s by Tuesday.
- Cooler temperatures return for the second half of the week.
- No significant precipitation expected Saturday through Friday.
DISCUSSION
Issued at 110 PM EST Fri Nov 6 2026
Well defined upper low centered near Saginaw Bay (Lower MI) with several weak disturbances/troughs rotating around the feature as it drifts slowly ESE reaching western NY by 12Z Sat. Weakly convergent flow along the eastern shores is keeping the main area of rain showers from South Haven to South Bend. Instability and favorable fetch peak into mid afternoon with combination of lowering inversion heights, departing low and core of coldest air shifting east should lead to a downward trend into tonight. Kept some lingering pops into the overnight before ending. Temperatures tonight will drop into the low to mid 30s, coldest outside of any lake effect cloud cover.
Low level WAA will commence on Saturday, but bulk of greatest increase will occur in the afternoon, limiting impacts on afternoon highs to the lower 50s. After one more cold night in the lower 30s, high temps will begin to rebound a few degrees each day into Tuesday with a return to above normal levels (low to mid 60s) by Tuesday.
A semi zonal upper flow will be interrupted by a northern stream wave, with a front pushing into the area by Wednesday. The trough will deepen into the second half of the week with additional waves move through the flow. The main impact appears to be a return to near or somewhat below normal temperatures to end the work week.
Some lake effect shower chances could arrive Thu/Fri, but overall flow right now may favor portions of far NW Indiana into NE Illinois.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1214 AM EST Sat Nov 7 2026
Lake effect showers/drizzle have diminished over the last couple of hours and will continue to do so over the next few hours. Then mainly MVFR cigs will be expected with the fairly moist surface layer from the recent rainfall. Drier air looks to begin pushing in by early afternoon (19-20z timeframe) on Saturday and should help to mix out the lower clouds and bring a return to VFR conditions through the remainder of this TAF period. Westerly winds up to 10 kts expected this period.
