752 FXUS63 KGRR 171827 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 227 PM EDT Tue Sep 17 2024 .KEY MESSAGES... - Dry and warm weather continues through midweek - Slight chances for rain late this week into next week && .DISCUSSION... Issued at 330 AM EDT Tue Sep 17 2024 - Dry and warm weather continues through midweek Ridging at the sfc/aloft will continue to dominate the wx pattern through midweek bringing mostly clear to partly cloudy skies and warm temps. High temps today will be a bit cooler than yesterday as h8 temps cool a bit to around 13 C. This in conjunction with ample sun will result in high temps reaching the low to mid 80s today. Mins tonight will be mostly in the 50s with potential for some patchy shallow ground fog again during the early morning hours Wednesday. High temps Wednesday will once again reach the low to mid 80s as we continue to have rather large diurnal temp swings with a relatively dry airmass in place. - Slight chances for rain late this week into next week The influence of the blocking high may begin to weaken and translate east later in the week, allowing some jet streaks and upper-level troughs or lows to move closer to our region. Per ensembles, the earliest chance of measurable rain may be Friday, though this is only a slight chance given so few solutions producing rain. The cold front that will approach Michigan, associated with a Dakota-Manitoba low, is likely to get washed out. There is a little better chance of rain around Sunday, which more EC ensembles are clustering toward as a more robust northern stream low moves over the Upper Midwest. However, southern stream ridging from Texas to the Great Lakes at that time does complicate the picture. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 215 PM EDT Tue Sep 17 2024 Another round of patchy mist/fog Wednesday morning should reduce visibilities to MVFR/IFR conditions. Main areas of concern will be JXN, LAN, AZO and BTL with lower restrictions expected at JXN. Any reducing conditions will improve between 13Z at 15Z. High pressure with VFR cigs and vsbys will dominate the rest of the period. && .MARINE... Issued at 330 AM EDT Tue Sep 17 2024 Sfc ridging will continue to result in light winds in the 5 to 10 kt range which will become onshore in the afternoon and early evening daily. Wave heights will remain aob 1 ft through midweek. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None. MARINE...None. && $$ DISCUSSION...Laurens/CAS AVIATION...Ceru MARINE...Laurens
