Area Forecast Discussion National Weather Service Detroit/Pontiac MI 1223 AM EST Thu Feb 25 2021

AVIATION.

Sky cover trends progress favorably heading through the late night as a colder and dry NW flow helps break up low clouds. As this process continues, mostly clear sky results across SE MI leaving attention toward Lake Michigan for assessment of stratocu activation as the wind turns toward the west during the morning. High pressure inbound from the Midwest toward the Ohio valley brings the westerly wind shift in Lower MI which carries the cloud field from Lake Michigan into the SE MI terminal corridor by afternoon. The nearly due west flow favors low end VFR broken ceiling more toward FNT and mbS while forecast data indicates greater coverage is also possible toward PTK to the DTW corridor on pace to move into Ontario by Thursday evening.

For DTW . NW wind dropped below crosswind threshold as breaks developed in the clouds during late evening. Light NW to W wind continues through the morning with a brief passing of low end VFR stratocu. VFR ceiling below 5000 ft becomes more likely during the afternoon.

DTW THRESHOLD PROBABILITIES.

* Moderate for ceiling at or below 5000 feet during afternoon.

PREV DISCUSSION. Issued at 309 PM EST Wed Feb 24 2021

DISCUSSION .

Warm sector in advance of approaching cold has remained relatively cloud free over much of the forecast area this morning into early afternoon with temperatures responding and climbing into the upper 40s to lower 50s along and south of I-69 with slightly cooler readings north where clouds have been more persistent. With gusty west to southwest winds and dew points into the lower to mid 30s, the slow/steady snow melt that began yesterday has continued.

The aforementioned cold front will progress quickly northwest to southeast across the region from late afternoon into this evening as a compact, yet vigorous, shortwave over northern lower Michigan and northern Lake Huron continues east into Ontario/Quebec tonight. Temperatures will drop into the 30s pretty rapidly this evening as cold air advection ensues with winds veering to the northwest. By early Thursday morning, low temperatures will be back into the teens to lower 20s.

This colder air mass will remain in place into Friday, but with high temperatures only settling into the lower to mid 30s Thursday before rebounding into the upper 30s to around 40 on Friday as the core of the cold air shifts east/southeast through eastern Canada and only grazes the central Lake Greats region.

At the same time, upper heights will build Friday into Saturday as ridging develops downstream of a develop upper trough over the western CONUS. This will lead to moderating temperatures into the weekend with highs well into the 40s in most locations both Saturday and Sunday. There remains a chance of light rain/snow late Friday into into early Saturday morning as a shortwave of Pacific origin ejects into the area as upper energy digs into the west coast.

However, that is really the only notable period for measurable precipitation (and not much at that). The next shortwave to ejects form the western CONUS in a similar fashion passes largely north of the forecast area and phases to some extent with a northern stream component late Sunday into Sunday night. So any precipitation with this system looks to be limited to a few sprinkles/flurries Sunday night into early Monday as this system passes and another cold front settles into the region. The arctic air mass in the wake of this cold front also looks to shift largely east/southeast across eastern Canada early next week with the southern edge impact Southeast Lower Michigan. As such, at this time highs are only expected to settle back into the 30s Monday/Tuesday.

MARINE .

Deepening low pressure system in place over Ontario and its attendant cold front has steadily increased wind speeds across the Great Lakes as wind direction continues to back from the west- southwest to northwest. A secondary cold front, now in place across northern Lake Huron, will reinforce northwesterly flow across the lakes tonight and overnight and will usher in even colder air to the region. A strong pressure gradient already in place from the aforementioned low pressure system in conjunction with a building energetic wind field aloft and increasing instability will allow for gusts on the order of 30 knots to persist late tonight and into the early morning hours, mainly confined to northern and central Lake Huron. Isolated gusts to gales are also possible during this time frame given the northwest fetch in place. Wind speeds and gust potential will then quickly drop off throughout Thursday morning as high pressure builds across the area.
