Wintry weather is expected to bring snow to Issaquah between Tuesday night and Thursday morning.

National Weather Service forecasters don’t know how much will fall or if it will stick to the roads in Issaquah, because it’s showery and difficult to pinpoint.

Wednesday, which has a 60 percent chance of snow, is expecting a high of 41 degrees. The low that night is expected to be about 28 degrees.

Meteorologists expect clear skies Thursday and Friday, with highs in the upper 30s.

The potential for lowland snowfall is still a few days away, and the forecast could change.

Forecasters are also expecting heavy snow in the mountains, about 1-2 feet, starting Monday night.
