(Through Tonight)
Issued at 355 PM EST Sat Dec 2 2023

High Impact Weather Potential: Minimal. Snow arriving late tonight across far southwestern areas.

Pattern Synopsis/Forecast: Low amplitude ridging sits atop the Ohio Valley and Great Lakes this advance of longwave troughing making slow eastward progress into the central Plains.
Elongated high pressure stretched from Quebec westward into the upper MS Valley will become displaced east as the upstream wave and attendant developing surface response trek across the mid-MS Valley tonight and into the western Great Lakes by early Sunday.

Primary Forecast Concerns: Increasing precipitation chances late tonight.

Partly to mostly sunny skies across the majority of northern Michigan this afternoon with temperatures varying from the mid-30s to low 40s. Clouds will gradually increase this evening before thickening/lowering overnight as low pressure approaches from the southwest. Far southwest areas may get into some snow by 09-12z with any accumulation by 12z Sunday under half an inch. East south-east winds in advance of this system overnight combined with a marginally sufficient over-water thermal gradient may be enough to kick off a few lake effect rain/snow showers across northeast lower...again mainly during the second half of the overnight. Lows tonight spanning the 20s to low 30s area-wide -- coolest north of the bridge, warmest near the Lake Huron shoreline.

(Sunday through Tuesday)
Issued at 355 PM EST Sat Dec 2 2023

High Impact Weather Potential: Accumulating snow Sunday, likely leading to some slick roads across portions of northern Michigan.

Pattern Forecast: Low pressure alluded to above in the near-term forecast section crosses southeast Michigan and the Ohio Valley during the day Sunday. Lingering low-level moisture strips east of northern MI by Monday morning with mid-level shortwave ridging crossing the area during the day Monday. This in advance of shortwave troughing set to dive from the northern Plains into the western Lakes Monday night - Tuesday...potentially bringing additional snow shower activity to parts of the forecast area.

Primary Forecast Concerns: Snow accumulations Sunday through Sunday night. Additional snow shower potential Monday night - Tuesday.

Little overall change from the last couple of forecast cycles regarding Sunday's snow "event". Low pressure passing by to our southeast will place northern Michigan in a favorable spot for widespread precipitation...generally in the form of snow across the majority of the forecast area. Suppose a bit of freezing drizzle could mix in as precip commences, particularly across the higher terrain of interior northern lower. A rain/snow mix or all rain still appears to be the dominant p-type as you head toward Lake Huron, primarily from APN to Gladwin and points east -- owing to a deeper near-surface melting/warm layer.

With respect to accumulations, latest probabilistic guidance continues to focus highest chances of 2"+ over the interior higher terrain, generally ranging from 60-75%. Chances for 4" up a tick from yesterday...highest between 20-30%. Lower chances for those accumulation thresholds as you head into the Great Lakes collar counties and north of the Mackinac Bridge. Still not anticipating this will rise to winter weather advisory criteria, but given this being a wetter snowfall with SLRs ranging from 8-11:1, development of slick/greasy roads appears pretty likely across interior northern lower, including Interstate 75. The bulk of synoptic support exits stage right Sunday evening/overnight, although lingering wrap around low-level moisture with weak lake support may prove to be enough to continue light snow showers/drizzle/freezing drizzle chances with the moisture depth struggling to reach -8 to -10 C.

Lingering lake induced precip not out of the question Monday morning with much drier air advecting in from the north by afternoon.
Attention then transitions to late Monday night - Tuesday as a clipper system crosses the upper MS Valley and western Great Lakes.
Still a fair bit of uncertainty with respect to the track of this system, but latest trends suggest while it'll be plenty cold for snow to be the dominant p-type, a lack of deep moisture may limit the overall intensity and duration of snow. Highest chances for accumulation currently appear to be across far northwest lower MI.

(Tuesday night through Saturday)
Issued at 355 PM EST Sat Dec 2 2023

High Impact Weather Potential: Monitoring late week clipper system.

Longwave troughing continues to progress across the eastern half of the CONUS then begins to transition to a more zonal flow pattern towards the end of next week. Embedded shortwave troughing over the northern Canadian Plains progressing towards the Great Lakes Thursday continues a quasi-active weather pattern at the end of next week.

The main story later next week revolves around the chance of a clipper system bringing an extended period of precipitation to parts of the CWA. Potential for snowfall accumulation remains possible at this time with current guidance and will be monitored with future model runs.

(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1205 PM EST Sat Dec 2 2023

Primarily VFR conditions expected to continue area-wide this afternoon. However, as low pressure passes by to our south tonight into Sunday, increasing chances for MVFR and eventually IFR CIGs will be the rule from south to north tonight into Sunday morning. Snow will accompany this system, especially during the day Sunday with IFR to localized LIFR VSBY restrictions becoming likely.

Issued at 355 PM EST Sat Dec 2 2023

Sub-advisory winds/waves are expected to continue across northern Michigan's nearshore waters through the remainder of the weekend into early next week. Widespread rain/snow expected to arrive on Sunday before gradually diminishing Sunday evening/overnight.
