KEY MESSAGES
- Widespread accumulating snow today into early tonight.
- Occasional light lake effect snow showers Sunday into next week.
SHORT TERM /THROUGH SUNDAY/
Issued at 254 AM EST Sat Feb 8 2025
Pattern/synopsis: Deepening low pressure will move up the OH Valley today and tonight. Well, well north of the low track, an area of enhanced mid-level fgen forcing interacts with a screaming jet max. Well-advertised, widespread snow will result.
Forecast: A few lake effect flurries linger around the eastern UP, though better Superior bands are getting kicked northward.
Virga is over central lower MI, and parts of northern Lake MI.
More organized precip is back in parts of WI, though it will initially be a struggle for precip to make a big push into lower MI. Better forcing hangs back to the west for a while, and our antecedent airmass is on the dry side.
But as we move thru the morning, banded precip will push into nw lower MI (w of TVC). Broader -SN then expands eastward and northward, into pretty much off of northern MI by dusk. The precip shield then starts to exit east, though enough low-level moisture lingers to contribute to a lake effect snow transition overnight in nnw to nw flow areas.
Enhanced banded elements will occur today, as fgen maxes out this afternoon, maxed out vertically toward the top of the DGZ.
These bands look to be favored near and south of a Leland-OSC line. Snow accums rates will reach 1"/hour, at least occasionally. But the max omega and the DGZ are only very marginally aligned, and SLRs will be impacted as a result (circa 17:1 expected). Another factor that will help keep impacts somewhat muted is that surface winds will be quite light today into early evening. Only as the system pulls further away later tonight does a bit of a northwest breeze develop/
Snow amounts today/tonight for TVC/MBL/CAD/HTL will be close to 6". Lesser amounts to the east and north; 4-5" for OSC/Mio/GLR, around 3" for PLN/APN, less than that in the UP. Given light winds, will not be too gung-ho with amping up headlines. No warnings anywhere. But have expanded the advisories into Antrim/Otsego/Oscoda Cos.
High temps today in the mid to perhaps upper 20s. Lows tonight range thru the teens.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Issued at 254 AM EST Sat Feb 8 2025
Pattern Synopsis and Forecast:
Generally speaking, near to slightly below normal height anomalies are anticipated for the early to middle portions of this week.
Consequently, some snow/lake effect will be possible at times, esp Sunday into Monday, then again on Tuesday as a frontal boundary passes through the region. Could certainly see at least a couple of inches across portions of Chippewa county over this period.
Meanwhile, heights build significantly across the northern latitudes, dropping the PV south in the vicinity of Hudson Bay. This signifies a release of cold air down into the lower 48, with the potential for an active wintry pattern somewhere east of the Mississippi. Certainly a cold week upcoming (highs in the teens, lows single digits above to at least single digits below zero) as portions of the cold airmass bleed eastward behind the frontal boundary on Tuesday.
First system of potentially a couple to watch will be around the Thursday time frame. All major deterministic guidance have a low pressure system forming across the Deep South and moving northeast as a trough swings in from the west. Theme has been for this system to stay generally east of N MI, at least the main impacts. However, there are a few pieces of guidance suggesting a track up into OH/Lake Erie/etc, and some deterministic guidance this run (00Z 8th) shifted little W/NW. Thus, worth keeping an eye on the trend in the coming days. Certainly more synoptic fun thereafter, as supported by the progged upper level pattern. Details hard to discern at this range but another feature to watch heading into next weekend.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
Issued at 1240 PM EST Sat Feb 8 2025
Conditions currently widespread MVFR/IFR due to widespread light to moderate snow. Terminals along the Lk MI coast are seeing some of the worst conditions, with that focus transitioning to terminals south of M-72 over the next few hours. Worst conditions likely from 21Z through 01Z in the aforementioned area (including KMBL/KFKS/KCAD/KHTL). Widespread snow will exit to the east after 00Z, with narrow bands of SN leading to chances of IFR cigs and vis over eastern upper terminals.
Impacts should diminish shortly after 16Z. -SN and MVFR cigs will linger over northern lower terminals through ~10Z. Light winds through the period become NW/N AOB 8kts after 06Z.
