Area Forecast Discussion National Weather Service Detroit/Pontiac MI 708 PM EDT Mon Jun 14 2021

AVIATION.

The potential for thunderstorms diminishes with sunset while some showers linger a few hours into this evening having additional support from the upper level trough. The greatest coverage is expected to be in SW Lower MI but with some activity brushing the SE MI terminal corridor with a brief MVFR restriction in higher rainfall rate. As showers diminish toward midnight, a reinforcing cold front moves down from the northern Great Lakes late tonight and across SE MI Tuesday morning. Clouds within this frontal zone have scattered to broken coverage although any ceiling is expected to be low end VFR. Coverage decreases Tuesday afternoon as dry and cooler air builds in on a north wind gusting around 20 kts at times into Tuesday evening.

For DTW . Late afternoon radar trends indicate diminishing thunderstorm potential while a stray shower remains possible during the evening. Partial clearing around midnight is followed by patches of VFR stratocu with a cold front late tonight. Any ceiling below 5000 ft is expected to be brief through Tuesday morning.

DTW THRESHOLD PROBABILITIES.

* Low for ceiling at or below 5000 ft tonight into Tuesday morning.

PREV DISCUSSION. Issued at 351 PM EDT Mon Jun 14 2021

DISCUSSION .

Cyclonic flow in place across the Great Lakes today as a weakening jetlet, evident on water vapor satellite imagery, now resides across the northern Ohio River Valley. Amplification of a longwave trough will continue tonight through the midweek period a series of shortwaves ripples through the greater flow regime. For today, strengthening mid-level cold pool of the building thermal trough and streams of cirrus clouds aloft will aid in continued cooling of the mid to upper levels of the atmosphere, increasing mid-level lapse rates to around 6 C/km. Concurrently, diurnal heating has increased instability with MLCAPE values building up to 500 J/kg. This will set the stage for the continued chances to see isolated to scattered rain showers with some thunderstorm activity this afternoon and evening. Effective bulk shear values around 20 knots will decrease through the evening hours which will limit organization potential of storms, however, steep low- level lapse rates and lowering freezing levels will bring the potential to see small pea sized hail with stronger storms. Otherwise, precipitation potential will fall off after sunset. Clearing trends behind earlier activity and northerly flow will allow overnight lows to drop into the 50s.

Limited precipitation chances are expected to hold over southwest Michigan, where the better CAPE gradient resides, as high pressure and associated dry air filters across Southeast Michigan. Northerly flow will advect very dry air across the Great Lakes 00Z Wednesday into 06Z Thursday, noted by EPS PW values dropping below .50 inches. This will result in dry weather with extended periods of sunshine through the midweek period. Daytime high temperatures are expected to hold in the 70s with dewpoints in the 40s for both Tuesday and Wednesday, making for very pleasant outdoor conditions.

High pressure will travel south into the Appalachians during the Thursday- Friday time frame, with return flow bringing some warmer temperatures and more moisture to end the week. Ensemble members are starting to converge on a shortwave feature set to travel near the Great Lakes at some point on Friday which will enhance moisture transport and will bring the next chance for showers or thunderstorms to the area.

MARINE .

A trough is currently working south through the region producing scattered showers and a few thunderstorms. As the trough gets south of the region tonight, Winds will become northerly and increase slightly as the gradient tightens between the exiting trough and incoming area of high pressure. Although winds look to peak around 20 to 25 knots Tuesday, the long fetch down the axis of Lake Huron will build wave heights across the southern basin. Small Craft Advisory may be needed for elevated wave heights along the Huron shoreline. Northerly winds will linger into Wednesday although speeds will decrease as the high take a stronger hold over the area.

DTX WATCHES/WARNINGS/ADVISORIES.

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