Low pressure will rapidly deepen today as it lifts from Illinois to eastern Lake Superior. Low level moisture transport within strengthening SSW flow will sustain MVFR based clouds into the afternoon. Despite the strong winds aloft, limiting mixing will keep wind gusts largely below 25 knots through the morning. Wind gusts may top 30 knots this afternoon as mixing increasing along and immediately in the wake of a cold front associated with the deepening sfc low to the north. The higher wind gusts probabilities are focused at FNT and mbS. Post frontal drying will erode the low clouds, allowing VFR conditions to prevail well into the evening.

For DTW...The cold front is forecast to pass through metro around 20Z and will be marked by a wind shift from south to southwest. Some peak gusts over 25 knots are possible along and behind the front.
Wind gusts are expected to rapidly


* High for ceiling below 5000 feet this morning and afternoon. Low this evening. Moderate after midnight.

Issued at 245 AM EST Sat Dec 9 2023


Wind Advisory issued today for Tri-Cities region, Flint Vicinity, and northern Thumb region for post frontal wind pop early this afternoon.

Yesterday's highs peaked out in the 50 (Kbax) - 55 (kdet) degree range, with 52 degrees representing the majority of sites.
Temperatures have held fairly steady early this morning, setting us up for an even warmer day/potential record setting warmth (see climate section for records). Despite surface dew pts climbing above 40 degrees, with the lack of snow cover and the ground not being frozen, low (IFR) clouds have not been an issue thus far, and still no signs of drizzle in the State yet. Upstream radar does show areas of light showers/drizzle lifting north through Indiana. If this activity associated with the isentropic ascent within the warm sector does not materialize/hold together this morning over southeast Michigan, there looks to be showers generated with the cold front this afternoon regardless, as the low level convergence looks good with SBcapes in excess of 50 J/kg. Stout mid level dry air/inversion will limit cloud tops under 8 kft. Based off current temps and latest guidance of MAV/ECM mos, see no compelling region to adjust maxes, and expecting most locations to end up in the upper 50s to near 60 degrees.

Compact shortwave and associated surface low currently over Western Illinois will be lifting north through Lake Michigan today, deepening in the process. 00z Euro ensemble mean and regional gem both indicating a low down to 993 mb by day's end, tracking through far eastern Lake Superior. Strong southwest low level jet (55 knots at 850 mb) with this system, but mixing depths this morning in the warm sector should be well below this max wind speed. However, there will be very good surge of low level cold advection at both the 925/850 mb levels and downward momentum behind the cold front this afternoon, mainly north of I-69, as the 6 hr rise/fall couplet (sub 20 mb) indicates the main surge into northern Lower Michigan. Based off soundings/mixing depths, especially per ARW, brief wind gusts aoa 45 mph is expected across the Tri-Cities region. Saginaw Vally does well with a southwest component, adding to the confidence.
Confidence then begins to diminish as one heads south, but even areas outside of the advisory should hit 30-40 mph. Wind fields drop off quickly late in the day, and winds become light for evening hours.

It should also be mainly dry for the evening hours as the mid level dry slot lingers and the low levels dry out post frontal. The exception looks to be across far eastern areas, as the left exit region of the 125 knot jet (250 mb) tracks in between the Central/Eastern Great Lakes, potentially supporting reveloping/lingering showers to persist for evening.

A progressive upper level pattern, lack of bitter cold air over Canada, and polar jet retreating north to James Bay by mid week will limit duration of the modest cold spell to end the Weekend into Monday.

Unfavorable northwest flow, low inversion heights and just modestly cold enough airmass around for Sunday to support a chance of flurries/isolated melting snow showers as the trough axis swings through Sunday night. 850 mb temps lowering to -12 C Sunday night will present a better chance of isolated light snow showers producing a dusting into Monday morning.

Shortwave ridging moves over the central Great Lakes for Monday evening ahead of the next shortwave trough, which tracks through the northern Great Lakes Tuesday morning. Model trends are for a deeper parent upper level low (~505 DAM at 500 mb) over northern Ontario, and a more substantial shot of cold air looks to be in store, per 00z Canadian and Euro. Although, a rather sharp north to south baroclinic zone/temperature gradient appears likely, with 850 mb temps aob -12 C around Saginaw Bay to -6 C near the southern Michgian border for Tuesday. In any event, would not rule out a few light snow showers/flurries north of I-69 with the brisk westerly flow, but subsidence and low level drying appears to be too strong at this time.


A low pressure system lifting out of the the mid Mississippi River Valley will arrive over Lake Michigan this morning and continue northeast across the Straits this afternoon. This system will drag a cold front across the central Great Lakes bringing widespread rainfall and an uptick in south-southwest wind speeds along the front during the afternoon/evening. Wind gusts may reach gales occasionally, but the expected shorter duration of these gusts precludes any gale headlines at this time. However, Small Craft Advisory conditions will develop across Saginaw Bay to Port Huron this morning and last through the early afternoon for most zones.
Elevated waves into the evening will keep small craft conditions in effect for Outer Saginaw Bay. Troughing overtakes the region with west to northwest winds ushering colder air into Sunday with the main frontal system off to our east. Precipitation chances will be limited to lake effect snow showers Sunday evening into Monday across the southeastern half of Lake Huron with the favorable flow.
The cold air brings greater instability over the lakes, but gust potential should top out around 25 knots or less for the early week period with a weak surface pressure gradient field.
