Area Forecast Discussion National Weather Service Northern Indiana 618 PM EDT Sat May 17 2025
KEY MESSAGES
- Windy this afternoon with west winds gusting near 35 mph at times.
- Remaining cool through next week.
- Periods of rain expected Tuesday into Wednesday.
DISCUSSION
Issued at 219 PM EDT Sat May 17 2025
Raw conditions will persist this afternoon thanks to gusty west winds, mostly cloudy skies and steady temps in the mid 50s to mid 60s. This is occurring under cool/cyclonic northwest flow on the southwest fringe of an exiting low pressure system. This system will gradually begin to lose its influence locally tonight into Sunday while tracking tracking toward New England and far southern Quebec. The result will be a less windy Sunday and a trend toward mostly sunny skies from sw to ne by the afternoon hours as large scale subsidence and drying overspreads.
Models continue to come into better agreement with a large low pressure system emerging over the Central Plains Monday, then slowly tracking east into the Mid MS/northern OH Valleys Tuesday into Wednesday. Monday should be mainly dry thanks to dry low level ene flow on the southern fringe of high pressure. Rain is then expected to overspread the area from sw to ne late Monday night into Tuesday as deeper moisture advects into a tightening frontal slope. Instability appears limited due to nearly moist adiabatic lapse rates north of the sfc boundary in central IL/IN. However, could see locally heavy rain and embedded thunder given the forcing and moisture quality (precipitable water values near 1.25 inches). Coverage and intensity of the rain shower activity may trend to diminish near the low pressure center a bit then into Wednesday as deeper moisture exits east.
Drier air does eventually filter in toward the end of the week in wake of this system with below normal temperatures holding in response to negative height anomalies merging over the Northeast and southeast Canada.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
Issued at 612 PM EDT Sat May 17 2025
VFR conditions will prevail for both TAF sites through the period. Winds will weaken diurnally tonight through Sunday morning and will again gust up to around 15 kts after 17-18z Sun with surface warming and increased mixing. Stratocu with minor lowering overnight will continue through this period.

IN...None.
OH...None.
