Area Forecast Discussion National Weather Service Northern Indiana 122 PM EDT Wed May 13 2026
KEY MESSAGES
- Light rain showers possible Friday morning (20-40% chances)
west of IN-15.
- Periodic chances for showers and storms over the weekend into early next week.
- Trending warmer and increasingly humid through early next week.
DISCUSSION
Issued at 122 PM EDT Wed May 13 2026
A surface low continues to lift northeast, now over the eastern shore of Lake Huron. Cyclonic flow off Lake Michigan has resulted in mostly cloudy skies through late morning but this is now clearing as high pressure centered over eastern Nebraska exerts its influence.
Cold tonight, but shy of frost/freeze concern as a steady northwest wind near 5 to 10 mph keeps temperatures right near 40 degrees.
High pressure remain in control Thursday allowing highs in the 60s which is still shy of the normal high near 70. A weak upper-level disturbance limps in from the west Friday and presents a 20-40% chance of showers mainly south of US 30. Preceding high pressure and dry air is a limiting factor along with modest forcing overall. Look for a greater coverage of showers and thunderstorms, though not a washout, Saturday and Sunday. With favorable moisture flux from the Gulf along the western edge of a subtropical ridge, an orphaned front from a departing Canadian low lingers over the Midwest and becomes the focus for scattered showers and storms at times.
The aformentioned ridge is maximized over the Appalachians Monday resulting in highs well into the 80s. Cannot rule out a 90-degree reading, but the general concensus from a number of NWS offices was to lower high temperatures Monday away from 90 degrees, noting a 4- degree bias correction. Nonetheless, becoming very warm this weekend through Monday. Cooler and stormy Monday night through Tuesday as a cold front moves through. SPC day 6 outlook threatens to creep east into northwest Indiana through time with marginal severe weather ingredients noted.
AVIATION /18Z TAFS THROUGH 18Z THURSDAY/
Issued at 1148 AM EDT Wed May 13 2026
