687 FXUS63 KGRR 151900 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 200 PM EST Sun Nov 15 2026 .KEY MESSAGES... - Dry and Warmer through Wednesday - Chance of Rain Thursday and Saturday/Sunday, Mild && .DISCUSSION... Issued at 200 PM EST Sun Nov 15 2026 - Dry and Warmer through Wednesday A stretch of nice weather is expected as high pressure builds into the area. We`ll be stuck in a pattern where an upper level ridge is over the eastern CONUS and a trough over the western CONUS. During this time we should see mostly sunny to partly cloudy skies and temperatures warming each day as low to mid level temperatures rise. Highs the next few days will be in the 50s with lows in the mid 20s to low 30s tonight warming into low to mid 30s the next few nights (warmer near the lake). - Chance of Rain Thursday and Saturday/Sunday, Mild The ridge axis shifts east a little bringing southwest flow to the area and warm air advection. This will allow for a couple shortwave troughs to swing through Thursday and over the weekend. Thursday`s wave is largely north of the area and could keep rain chances (20 percent) to the north as well. A deeper trough shown in the ensembles moves through over the weekend, but there is low confidence in the exact timing. Winds could be breezy with each system with the potential for 40 mph gusts along the lakeshore this weekend. Temperatures are expected to be in the mid 50s to mid 60s with lows in the 40s. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
