Area Forecast Discussion National Weather Service Detroit/Pontiac MI 1152 PM EST Mon Nov 30 2020

AVIATION.

Persistent area of mainly light intensity snowfall will remain anchored across southeast Michigan through Tuesday morning. Low MVFR to IFR restrictions will remain firmly entrenched at DTW/YIP/PTK - lowest restrictions within a modest increase in snowfall intensity expected between 08z and 14z. The back edge of this snow will ten to align near FNT, offering at least intermittent bouts of light to snow and accompanying reduction of visibility. mbS remains outside of any meaningful snowfall and carries simply MVFR stratus this period. Prevailing north-northwest remaining gusty during this time, a slight lull in overall magnitude overnight before strengthening again Tuesday. This moisture will gradually vacate the region toward midday, with conditions easing back into VFR thereafter.

For DTW . Long duration of mainly light accumulating snow remains over the terminal through Tuesday morning. Some increase in intensity with a greater drop in visibility possible between 08z and 14z. West-northwest winds will prevail through the period, with gusts up to 25 knots at times.

DTW THRESHOLD PROBABILITIES.

* High in precip being all snow through Tuesday.

* High in ceilings remaining below 5000 feet through Tuesday afternoon.

PREV DISCUSSION. Issued at 929 PM EST Mon Nov 30 2020

UPDATE .

Noted downturn in both snowfall intensity and westward expanse locally this evening. This behavior generally expected as mid level ascent wanes briefly. A secondary window for meaningful deformation remains for overnight and early Tuesday /06z-14z/ as the northern Ohio valley upper low pivots northeast with time and consolidates with lead energy now racing into Ontario, effectively stalling this axis and sustaining a low intensity, long duration snow for eastern sections. Based on recent hi res model and observational trends, outgoing forecast will simply sharpen the west to east gradient of expected accumulation going forward. This allows for an additional couple of inches to still fall generally east of a Caro to Lapeer to Pontiac to Ypsilanti line, with upwards of 3 to 4 across the eastern thumb noting the greater proximity and longer residence time for better ascent. Snowfall rates will remain modest throughout for most locations, but still sufficient for roadways to become snow covered and slippery Tuesday morning as temperatures ease down into the upper 20s. Consideration given to drop Lenawee/Washtenaw counties from the advisory, but prefer to leave the door open for some renewed westward expansion of the snow during the early morning hours first before making a definitive call.

PREV DISCUSSION . Issued at 353 PM EST Mon Nov 30 2020

DISCUSSION .

The amplified upper wave responsible for the winter storm lifting across the eastern US is well defined in water vapor imagery over the Great Lakes and Ohio Valley this afternoon. This wave becomes a broad closed upper low over the eastern Great Lakes tonight with a lobe of the surface low retrograding back over western Lake Ontario. The western outskirts of the system's lift / snow shield have been positioned over SE Michigan today with weak isentropic ascent and transient waves of fgen being the main forcing for the light snow. This relatively disorganized forcing will strengthen overhead tonight as waves of midlevel fgen rotate in from the low off to the east. Temperatures falling to the upper 20s late this afternoon will allow snow to more readily accumulate on roads, and residual moisture on roads may freeze where snow isn't falling.

Light to at times moderate snow will work into eastern portions of the CWA tonight with the peak in snowfall rates expected after midnight through the early morning on Tuesday. Light snow then tapers off gradually for most areas during the daylight hours Tuesday as the forcing strips off to the east. The exception is the eastern Thumb region where ascent remains a bit more prolonged as ribbons of fgen and PV pivot overhead. Extra lift from lake enhanced banding may also lead to some overachievement in this region. Overall, 3 to 6 inches of snow look most likely across the Thumb but with localized areas seeing higher totals. 2 to 4 inches will be most likely for the Metro Detroit region by Tuesday afternoon. A Winter Weather Advisory remains in effect for much of the CWA as road conditions will likely be impacted by this prolonged light snowfall.

Cold and blustery conditions expected on Tuesday as the low keeps a stout northwest gradient and wind field in place. Temps peak in the lower to mid 30s but wind chills remain in the teens and 20s owing to winds gusting upwards of 25 mph. The coldest air of the week is associated with the low pressure system, and when it departs on Tuesday evening it will usher in a more mild air mass for the midweek. Clouds move out by Wednesday with highs warming into the 40s - right around normal for early December. Shortwave ridging will reside over the Great Lakes Wednesday into Thursday as the low moves off to the northeast and a digging trough-turned-cutoff-low wobbles over the central and southern Plains. The next cold front and resultant chance of precip then moves through on Friday.

MARINE .

A strong low pressure system will impact the region through the first half of the week. This low currently centered over Pennsylvania will reach Lake Ontario this evening and then will stall and wobble about over the eastern Lakes Tuesday before lifting northeastward on Wednesday. Northerly flow and a cold unstable airmass, combined with a tightening pressure gradient will result in gale force winds and waves in excess of 10 feet through Tuesday evening. Gale Warnings continue for the majority of the Lake Huron basin with small craft advisories for part of Saginaw Bay, Lake St Clair and Lake Erie now into Tuesday. The low will be slow to drift away from Ontario/Quebec Wednesday which will keep unstable conditions and around through mid week. Winds will remain elevated though likely below Gale force while backing to more northwesterly.

HYDROLOGY .

A prolonged period of light precipitation is ongoing as a sprawling low pressure system lifts across the eastern US. Southeast Michigan resides on the far western edge of its precip shield with light snow expected to continue tonight into Tuesday afternoon or evening. The highest totals will be found in the eastern Thumb and east of I-94 (Port Huron to Detroit) and I-75 (Detroit to Monroe). Liquid equivalent totals of generally 0.25 to 0.50 inches are expected with locally higher totals across the eastern Thumb where lake effect snow banding may occur. No flooding concerns are anticipated from this prolonged precip.
