AVIATION.

Favorable aviation conditions through tonight. Mid clouds in place over southeast Michigan slowly peeling off to the east this evening, but high clouds likely persist tonight. Steady southerly winds around 10 knots (40 knot low level jet around 2000 feet) overnight advecting warmer and moist air from the south Sunday morning, eventually leading to an MVFR deck of clouds developing. Exact timing is uncertain, but somewhere in the 13-17z time frame. South- southwest winds continue to increase during the morning hours, with gusts of 20-25 knots expected.

DTW THRESHOLD PROBABILITIES .

* High confidence in cigs aob 5000 feet after 14z Sunday.

PREV DISCUSSION. Issued at 357 AM EST Sat Dec 7 2019

DISCUSSION .

Cool northwest flow aloft will usher in a minor shortwave across the northern Great Lakes with little consequence to southeast Michigan this morning. Expecting a quiet day today under the influence of a surface high pressure and an overall dry airmass. Low stratus from yesterday have relinquished their hold over the area, but mid/high clouds are now moving in association with warm air advection aloft. Southerly return flow will kick in as the surface high moves into the eastern Ohio Valley towards the late afternoon. This may bring some breaks in clouds later today as flow tries to draw them to the north. Low level warm advection will commence too late in the day to see a response in daytime highs which will hold in the 30s.

Strengthening low level 40-50 knot jet will help advect warm/moist air into the area on Sunday. An increase in 850 mb temperatures to around 2C by 12Z Sunday morning that will support high temperatures in the 40s. Tightening pressure gradient between high pressure off the east coast and troughing across Ontario will bring an uptick in southerly winds with gusts to around 20-30 mph by late Sunday morning and afternoon. A frontal boundary will be sagging southward and and eventually become stationary. This will become the focus for convection later in the day Sunday into Monday when a low pressure system develops near the left exit region of the 130 kt southern stream jet and moves northeastward along this frontal and through Michigan. The track of the low keeps southeast Michigan on the warm side with another day of mostly 40s to possibly 50 degrees towards the MI/OH border for Mondays high temperatures. This means that low level thermal profiles will be warm enough for p-type to fall as rain through most of Monday. Chances for lighter precipitation will start Sunday evening with bulk of precipitation falling early Monday morning and afternoon. Cold air will begin filtering into Michigan Monday night as the low lifts into Quebec bringing potential for a transition from rain to snow with any lingering precipitation on the back side of the system or from lake enhanced precipitation under cold low level northwest flow. Thermal trough then sets up for the mid-week period bringing arctic air to the Great Lakes along with opportunities for lake effect snow. Temperatures at 850 mb will drop to around -20C by Wednesday afternoon bringing high temperatures down into the teens and low 20s. The coldest morning of the week will be Thursday morning with lows in the lower teens and wind chills dropping into the single digits.

High pressure will be passing through the Michigan and to the east during the day on Thursday turning low level winds to the southwest. This will help drive the arctic airmass out of the region towards the end of the work week. This will then bring gradual warmup back into the 30s by Friday. Conditions remain mostly dry until the weekend when the next low pressure system lifts out of the Gulf and across the eastern Ohio Valley potentially bringing the next chance at impactful weather to southeast Michigan.

MARINE .

High pressure builds into the southern Great Lakes early this morning. The high will be quick to depart to the east by Sunday evening while a cold front begins to sink into the northwestern Great Lakes. The result will be a strengthening southwesterly gradient over the region today. Developing low pressure over southern Ontario will lead to increased warm advection which will result in a stable profile over the cool water, but a strong low- level jet and long southwesterly fetch will bring the potential for gusts to gale force over northern and central Lake Huron for much of Sunday. A Gale Watch has been issued for this area. Another low pressure system then tracks through the region on Monday evening, bringing widespread rain for most of the area and snow for northern Lake Huron. This system will usher in a much cooler air mass and unsettled conditions for the early part of next week.

HYDROLOGY .

Next chance for an extended period of rainfall will start Sunday evening and continue through Monday. Increased moisture transport will bring PWAT values nearing 0.8 inches into southeast Michigan as a low pressure system moves across Michigan. Rainfall totals will range mostly between a quarter of an inch to a half inch. Higher totals will be possible if any training of heavier rainfall occurs over any location. A transition to wintry mix will be possible if any precipitation lingers long enough after the system passes off to the northeast. Rainfall may lead to ponding of water in low-lying areas and small rises on area rivers.

DTX WATCHES/WARNINGS/ADVISORIES. MI . NONE. Lake Huron . Small Craft Advisory from 4 AM to 4 PM EST Sunday for LHZ421-422- 441-442.
