Area Forecast Discussion National Weather Service Grand Rapids MI 255 PM EDT Fri Jun 11 2021 LATEST UPDATE... Synopsis/Discussion/Marine .SYNOPSIS... Issued at 255 PM EDT Fri Jun 11 2021 - Chances for rain into this evening and on Saturday - Cooling off and drying out next week && .DISCUSSION...(This evening through next Friday) Issued at 255 PM EDT Fri Jun 11 2021 - Chances for rain into this evening and on Saturday Some strong updrafts with reflectivity cores above the minus 20C level are currently seen on radar just off the northeast corner of the forecast area and some of these could impinge on Clare County and our far eastern counties into the evening before they diminish after sunset. Patchy dense, but shallow fog is possible in spots again tonight then clouds and showers move in from the west during the morning and afternoon as a sfc trough/weak cold front moves through. Expect a few stronger updrafts with the chance for small hail and strong downdrafts in the afternoon, generally east of US 131 where LIs of minus 5 to minus 8 and CAPES over 2000 J/kg are progged during the afternoon. One limiting factor is deep layer shear is relatively weak at around 20 to 25 knots. - Cooling off and drying out next week Longwave pattern becomes more amplified across the CONUS early next week with upper troughing across the NE CONUS and ridging in the West. A cold front could bring rain showers Sunday night, followed by drier and cooler weather as a Canadian anticyclone builds into the Great Lakes. Dew points will be falling quite dramatically, and low temperatures in the 40s are possible by Wednesday morning. Dry weather should prevail until Friday as northern stream shortwave trough tops the western ridge and a sfc cold front sags into the central Great Lakes bringing the chance of showers. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1200 PM EDT Fri Jun 11 2021 Fair wx with VFR conditions will continue at most of the terminals this afternoon and evening. Isolated showers and storms are expected to develop mid to late afternoon and could clip KLAN but should otherwise stay north to northeast of the rest of the terminals. Patchy fog will develop overnight and will likely impact all the terminals during the early to mid morning hours Saturday and cause conditions to deteriorate to MVFR and potentially IFR. Fog will dissipate by late morning Saturday with VFR conditions to follow through 18Z. Development of scattered showers and isolated thunderstorms is possible tomorrow but potential is too low to warrant inclusion in any of the terminal forecasts for now. && .MARINE... Issued at 255 PM EDT Fri Jun 11 2021 Areas of fog are possible again tonight. Scattered thunderstorms are expected on Saturday. Northwest winds could gust over 20 knots on Saturday afternoon and evening but most of the weekend should see winds less than 20 knots and waves less than four feet. && .GRR WATCHES/WARNINGS/ADVISORIES...
