Area Forecast Discussion National Weather Service Detroit/Pontiac MI 613 AM EDT Thu Apr 22 2021

AVIATION.

Scattered strato-cu dropping southeast into the area will fade, but SCT-BKN diurnal cumulus will then redevelop later this morning with bases aoa 5000 feet owing to the dry low level air mass in place. West northwest winds of 10 to 20 knots can be expected by midday with winds backing to the southwest tonight.

DTW THRESHOLD PROBABILITIES.

* Low for ceiling at 5000 ft from late morning into the afternoon.

PREV DISCUSSION. Issued at 338 AM EDT Thu Apr 22 2021

DISCUSSION .

Observations this morning show temperatures that have falling well into the 20s for most of southeast Michigan. Temperatures in the low 20s are currently being observed in Bad Axe. The combination of mostly clear skies and the resident cold airmass that moved into the region is supporting these sub freezing temperatures. The Freeze Warning for all of southeast Michigan will remain in place until 7 am. Daily minimum temperature records at a couple climate sites are at risk of being broken this morning, Flint (23 set in 2013) and Saginaw (25 set in 2013). Current observations at press time show Saginaw currently tied at the record and Flint within a few degrees. Detroit's record of 20 set in 1875 will not be in jeopardy of being broken.

Mid-upper level shortwave ridging will build into the western Great Lakes today while a surface high pressure drives across the Ohio River Valley. This will increase subsidence over the area resulting in limited cloud cover today. A tightening pressure gradient north of this high pressure will be enough to support some gusty afternoon conditions as diurnal mixing depths increase to around 2 km. Latest guidance is not quite as strong in regards to the gusts. Forecast wind gusts for this afternoon will be be around 20-25 mph. Westerly winds will begin to usher in warmer air across southeast Michigan throughout the day. More sunshine today will help daytime highs recover to around 50 degrees for most inland locations.

Continued warming trend into Friday as the ridge dampens and more zonal flow is present throughout the column. Temperatures at 850 mb improve to around 0C as the coldest air is shoved to the east. This will help daytime highs from Friday increase to around 60 degrees. A shortwave moving out of the desert southwest on Friday will generate a low pressure system that is forecast lift northeast out of the southern Mississippi River Valley and into the Ohio River Valley by Saturday evening. This system will bring the next chances for rainfall to southeast Michigan. Good entrance region jet dynamics and some interaction between the northern and southern stream jets will support precipitation up the frontal slope into southeast Michigan Saturday morning. Thermal profiles will be supportive of all rain. After a subtle cool down on Sunday in the wake of the system on Saturday, a longwave pattern shift across the CONUS will bring well above normal temperatures into the middle of next week.

MARINE .

Expansive area of high pressure will slide from the central Plains toward the east coast through the end of the week. Cool northwest flow will relax while backing to more westerly today while remaining generally below 20 knots. Winds then back to the southwest on Friday as the high reaches the east coast putting us on the northwest quadrant. We will remain on the northern periphery of this high until Saturday when the next low approaches the region from the southwest while a trough drops southeast into the region out of Canada.

DTX WATCHES/WARNINGS/ADVISORIES. MI . Freeze Warning until 8 AM EDT this morning for MIZ047>049-053>055- 060>063-068>070-075-076-082-083.

Lake Huron . NONE. Lake St Clair . NONE. Michigan waters of Lake Erie . NONE.
