Area Forecast Discussion National Weather Service Detroit/Pontiac MI 730 PM EDT Sun Mar 29 2020

AVIATION.

Expansive area of low level moisture will remain firmly entrenched through this taf period, resulting in widespread stratus. Brief window for VFR level restrictions early this evening, before ceiling height gradually lowers with time through the night. Predominant MVFR into Monday, with perhaps a brief drop into IFR possible during the morning period. A firm southwest wind this evening will gradually ease through the night. Gusts in excess of 30 knots remain possible prior to midnight, before decreasing in magnitude overnight. Winds gradually veering to west and then northwest on Monday, gusting at times 20 to 25 knots.

For DTW . Southwest winds gusting in excess of 30 knots at times through late evening, then gradually diminishing overnight. Winds veering to westerly on Monday, gusting 20 to 25 knots at times. This will introduce a low potential for gusts to near crosswind thresholds from 290 degrees during the afternoon. Low stratus holds through the period.

DTW THRESHOLD PROBABILITIES.

* High in ceiling at or below 5000 ft through Monday.

* Low confidence in wind gusts exceeding crosswind threshold from 290 degrees Monday afternoon.

PREV DISCUSSION. Issued at 313 PM EDT Sun Mar 29 2020

DISCUSSION .

The upper low now churning just south of Green Bay, Wi will move across nrn Lower Mi and nrn Lake Huron this afternoon and evening. The region of low level moisture wrapping around this system and ascent tied to mid level short wave impulses rotating along the base of the upper low will sustain scattered to numerous rain showers well into tonight. A peak of sun earlier today pushed temps into the low 60s over much of the area. This steepened the low level lapse rates enough to support a few intervals of strong winds along the lead edge of surface cold push. Ongoing low level cold air advection is dropping temps into the 40s. The low level moistening and rain showers is also reducing the degree of boundary layer mixing upstream. This will only persist through the evening and will support a decreasing trend in the southwest wind speeds and gusts into the early evening hours.

The upper low will depart to the east of the region on Monday. Lingering low level cyclonic flow into Se Mi, residual low level moisture and a late March sun angle my be enough to support a few diurnally enhanced light rain showers. Persistent low level cold air advection tonight will drop temps into the 30s. Subtle low level cooling into Tuesday afternoon and ample cloud cover will keep daytime temps in the 40s. As the upper low elongates to the east, lingering mid level troughing will hold to the north of the Great Lakes with decent mid level confluence across srn Mi. This will force a southern stream wave to remain suppressed well to the south of the state on Tuesday, with cool and cloudy conditions holding across Se Mi under residual low level moisture. Amplification of the flow across NOAM Wed into Thurs will force mid level ridging across Lower MI, sustaining dry conditions; perhaps into the weekend.

MARINE .

Afternoon observations across southern Michigan support gale force gusts on Saginaw Bay and Lakes St Clair and Erie. The low pressure advancing across the northern Great Lakes tonight will slowly weaken. This will lead to a slow but steady decrease in the southwest wind speeds during the night. The low will continue to weaken as it exits to the region to the east on Monday, leading to continued diminishing trends to the winds as they veer to the northwest. High pressure will expand across the region by Tuesday, leading to tranquil marine conditions through mid week.

DTX WATCHES/WARNINGS/ADVISORIES. MI . Wind Advisory until 8 PM EDT this evening for MIZ060>063-068>070- 075-076-082-083.
