Area Forecast Discussion National Weather Service Gaylord MI 645 AM EDT Sun Apr 20 2025 .KEY MESSAGES... - Widespread rain showers develops tonight and Monday, perhaps with a rumble of thunder south. - Cooler Tuesday before a warming trend commences the rest of the week. - Rain chances Tuesday night and again Thursday night into Friday. && .SHORT TERM /THROUGH TONIGHT/... Issued at 213 AM EDT Sun Apr 20 2025 ...Widespread showers developing tonight... Large area of high pressure remains centered over the Western Great Lakes region early this morning...producing mainly clear skies and light winds across Michigan. A few patches of low clouds are streaming into northern and western portions of our CWA...but overall wx is quiet and dry attm. Meanwhile...low pressure is developing over Texas...generating widespread strong/severe storms in the vcnty of this system. As we head into today...this Texas low will lift NNE...reaching the Iowa/Missouri border by 00Z Monday and then continuing into Central Wisconsin by 12Z Monday. Sharp closed upper low will be close in tow...centered just to the west of the surface low by early Monday morning. As usual...dry easterly low level flow ahead of this system will tend to initially erode incoming low level moisture/precip across our CWA. So after a partly to mostly sunny Easter Sunday... clouds will begin to increase from SW to NE across our CWA this evening. Chances of showers will also increase from SW to NE...but likely not until later in the evening and overnight as deeper moisture arrives. Our far SW CWA around MBL may experience a few rumbles of thunder thanks to the development of very limited and elevated instability. High temps this afternoon will range from the Upper 40s in Eastern Upper and far NE Lower Michigan along the Lake Huron shoreline to the upper 50s in our SW CWA around MBL and TVC. Low temps tonight will cool into the mid 30s to lower 40s. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 213 AM EDT Sun Apr 20 2025 Pattern Synopsis / Forecast: Low pressure will be on the move across Wisconsin by daybreak on Monday, cruising northeastward into central upper Michigan and north into Ontario by day's end. Ordinarily this track for low pressure would bring some attention to severe weather, but considering the associated cold frontal boundary will clear much of the area by midday Monday, not anticipating too much in the way of widespread thunder, let alone severe storms. Best shot for thunder likely favors south of M-72, with specific focus on the Saginaw Bay area, as the frontal passage may be just late enough to allow for some better instability to materialize for folks down there. As far as rainfall amounts go, probably an additional 0.25-0.50" across the eastern Yoop and far northern lower, with lesser amounts (0.25" or less, locally higher in any downpours / storms) south. Highs top out in the 40s north of the Bridge, and well into the 50s most elsewhere... with the exception of the Saginaw Bay area, which could balloon into the mid, perhaps even upper 60s with that later frontal passage. Post frontal airmass builds Monday night, with lows in the low-to-mid 30s (upper 30s by Lake Huron). Dry Tuesday and cooler... highs in the 40s north and near 50 to the mid 50s south (near 60 in Gladwin / Arenac). As stated by the previous forecaster, a textbook zonal flow regime materializes the remainder of the week, bringing a series of disturbances, that should draw progressively warmer air into the region through the week. These disturbances will be pretty quick moving, and instability starved, so generally, anticipating much of the activity comes in the form of some rain showers, perhaps a few rumbles of thunder the farther south one goes of the Bridge. The best chances for rain will be Tuesday night and Thursday night into Friday. Wednesday through the day Thursday appear dry... and will likely be the warmest days of the year (thus far... it is April after all) for a lot of places. With any breaks in the clouds, could easily see widespread upper 60s to mid 70s materializing south of the bridge (mid 50s to 60 in the eastern Yoop). Slightly cooler (but seasonable!) to close out the period... with highs holding in the mid 50s to mid 60s across the board. Normal highs: 52-62, normal lows: 31-40 && .AVIATION /12Z TAFS THROUGH 12Z MONDAY/... Issued at 645 AM EDT Sun Apr 20 2025 High pressure overhead will maintain dry wx and VFR conditions thru today. Clouds will increase this evening...with widespread rain showers developing later this evening into overnight ahead of deep low pressure lifting thru Missouri and into Wisconsin. Conditions will drop to MVFR as this precip develops. LLWS will develop overnight around TVC and MBL. Surface winds will remain from the east at around 10 kts today and this evening...strengthening to 15 to 25 kts late tonight. && .APX WATCHES/WARNINGS/ADVISORIES... MI...None.
