FXUS63 KAPX 270427 AFDAPX Area Forecast Discussion National Weather Service Gaylord MI 1227 AM EDT Mon Oct 27 2025 .KEY MESSAGES... - Dry with seasonable temperatures through at least mid-week. - Cooler with shower chances returning to end the week. && .SHORT TERM /THROUGH TUESDAY/... Issued at 213 PM EDT Sun Oct 26 2025 Pattern Synopsis/Forecast: Sharp upper level ridging in the process of building directly overhead early this afternoon, with its equally impressive surface reflection extending from the western Great Lakes east across much of northeast NOAM. Attendant deep subsidence resulting in dry weather across the Northwoods, with just some shallow lake enhanced cumulus rotating above the landscape. Filtered sunshine and a slowly modifying overhead airmass is resulting in temperatures that are running just a bit above normal...with current readings in the lower to middle 50s. Upper level high pressure will continue to expand north through the region tonight and Monday...shunting rather vigorous shortwave trough into the Tennessee Valley by Monday afternoon. Primary Forecast Concerns: Minimal...with main focus on temperature trends. Details: More quiet conditions tonight and Monday, with just some shallow Lake Huron induced clouds rotating into northeast lower and parts of eastern upper Michigan...especially again later tonight into Monday morning. Otherwise, near perfect conditions for an excellent nocturnal/diurnal temperature response tonight and Monday away from those lake cloud areas...with mostly clear/sunny skies and a dry low level environment. Again looking at widespread lows tonight down into the 20s in our interior colder locations...with readings staying several degrees "warmer" near the big waters and under those passing lake clouds. Highs Monday back into the lower and middle 50s. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Issued at 213 PM EDT Sun Oct 26 2025 Pattern Synopsis/Forecast: Rex block configuration to the large scale flow regime still expected to unfold this week as deep troughing closes off across the Tennessee Valley and upper level ridging "folds" across the northern Great Lakes and southern Ontario. Still evidence of rather significant changes heading into the end of the week as that Tennessee Valley low gets punted northeast in response to next southeast diving Canada Wave. Eventual formation of deep overhead troughing the likely result by this weekend...bringing the return to more classic start of November weather to the Great Lakes. Primary Forecast Concerns: Temperature trends and addressing late week shower potential. Details: Persistent dry east flow expected to now keep our area dry through at least Thursday. Mostly clear to partly cloudy skies expected, with likely an uptick in clouds during the afternoon hours with diurnally-driven shallow cumulus development. Temperatures will run near to a bit above specific normal values, with highs Tuesday through Thursday mostly in the 50s and lows in the 20s and 30s. As mentioned...return of deep troughing anticipated heading into the end of the week and weekend. Primary surface cyclogenesis within the front-side of this evolving trough currently anticipated to remain off to our south and east...and that is likely where the more significant precipitation will reside. Eventual retrogration of Atlantic moisture and likely development of lake moisture contribution within a cooling low and mid level environment will bring at least some threat for showers Thursday night into the weekend....with best shower potential becoming centered in favored lake effect areas with time. Temperatures will trend cooler, with highs Friday into the weekend likely not getting out of the 40s for most (actually rather normal for the start of November). && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1227 AM EDT Mon Oct 27 2025 Largely VFR. Watching some marine-driven cloud cover drifting west from Lake Huron. With calm winds, some BR / FG are possible... namely at APN, but to a lesser extent, CIU and MBL too. Anticipating the marine-driven clouds to drift over northern lower into the day... but cloud bases anticipated to remain VFR through the forecast period. E to SE winds will be a touch breezier than in recent days... with some 15kt gusts possible in the afternoon. && .APX WATCHES/WARNINGS/ADVISORIES... MI...None. MARINE...None. && $$ SHORT TERM...MSB LONG TERM...MSB AVIATION...HAD
