KEY MESSAGES
1) Unsettled weather moves back into the region Wednesday through the end of the week.
DISCUSSION
Key Message 1...Unsettled weather moves back into the region Wednesday through the end of the week.
The chance for showers and thunderstorms return Wednesday through Friday. An upper level trough will move into the Northern Plains/Great Lakes region and a return flow will bring moisture northward. The synoptic pattern suggests deep southwesterly flow will persist during this time. While confidence is low regarding timing and intensity of showers and thunderstorms, chances are higher in the afternoon to evening.
AVIATION /09Z MONDAY THROUGH FRIDAY/
IFR/LIFR flight conditions will continue this morning. Lingering showers will continue this morning as low pressure continues to slowly track eastward. Conditions will improve from west to east with VFR expected across western terminals between 15z and 18z, with KART returning to VFR between 21z and 00z.
Gusty northwest winds are expected this afternoon, especially for terminals in close proximity to Lake Ontario like KROC and KART.

Wednesday through Friday...Mainly VFR, however afternoon and evening scattered showers and thunderstorms will pose a risk for MVFR or below conditions at times.
