Area Forecast Discussion National Weather Service Northern Indiana 220 AM EDT Wed Apr 23 2025
KEY MESSAGES
- Isolated to scattered thunderstorms are possible through early afternoon, primarily across northwest Indiana and southwest Michigan. Otherwise, warmer temperatures.
- Widespread showers and thunderstorms on Friday. No severe weather is expected at this time.
- Brief cooler and drier weather for Saturday with temperatures warming back up through early next week.
DISCUSSION
Issued at 212 AM EDT Wed Apr 23 2025
A cluster of light/moderate rain is moving into NW Indiana from IL has all but fizzled out as it continues to move east into our area, due to decreasing instability. A few sprinkles here or there over far SW Michigan and NW Indiana remain possible overnight, but otherwise much of the earlier activity has diminished.
Another pocket of showers and thunderstorms, on the northward extent of the ongoing severe threat across the Plains, is currently firing up over Iowa. This convection should also decrease in intensity over time as CAMs suggest highest rain chances will be across NW IN through SW MI. No severe weather is expected, but some gusty winds might be possible with any stronger updrafts given the marginal environment. Otherwise, above average temperatures are expected with highs in the mid 70s.
Weak ridging characterized by increasing mid-level heights will promote continued warming into Thursday with afternoon highs climbing into the low 80s (70s near the Lake). While unsettled weather is expected on Friday with showers and thunderstorms looking highly likely (80-90% chance), considerable uncertainty exists in some features, including a large variation in afternoon CAPE values.
Current forecast projections are for around a half inch of precipitation with this system. A cold front will push through, bringing in cooler/drier conditions for the weekend, before temps start to creep back up during the beginning part of the week.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
Issued at 1257 AM EDT Wed Apr 23 2025
A stalled frontal boundary will bring widely scattered showers to areas west of US 31 this morning and early afternoon. Have added two PROB30 groups to the KSBN TAF to account for the low chances for precip. Winds will remain light out of the south today and VFR ceilings are expected to prevail through the duration of the forecast period. Have kept KFWA dry, but can't rule out a few showers in the vicinity later this morning.
