DISCUSSION.

The back edge of precipitation associated with the system relative isentropic ascent has pushed east of Michigan early this morning with some lingering snow showers along the Detroit River corridor at press time. These showers will push east within the next hour or two. The main concern in regards to hazardous travel this morning will be for slick spots to develop. Many roadways are now wet, though ground temperatures overall remain well above freezing. Observations show surface air temperatures that have dipped to freezing for much of southeast Michigan. Dewpoints are now in the teens across the Tri-Cities and a northwest wind will usher these dewpoints further south through the morning. Dewpoints in the teens in combination with the winds may be just strong enough at times to lead to wet bulb cooling effects that may cause a few localized icy spots to develop. This would mainly be on bridges, overpasses, and any other elevated roadways.

A secondary push of colder air into Michigan with the favorable wind direction will also support light lake effect snow showers working southward this morning off of Lake Huron. A surface trough moving over the Lake Huron will shift winds from the N-NNE, which will direct these showers inland. The eastern portions of the Thumb down to Port Huron will be the more likely areas to experience this activity today, but some scattered light rain/snow showers may reach as far west along the I-69 corridor to Flint or Lapeer during the afternoon. The secondary cold front passing this morning will send 850 mb temperatures down into the -8 to -11 C range by this afternoon. Expecting well below normal high temperatures today in the low to mid 40s for much of the inland areas. Slightly cooler temperatures in the upper 30s for the Thumb region. Gusty afternoon winds to around 20 mph will result in wind chills in the 30s. Fewer clouds tonight allow for better cooling conditions which will result in another night of well below freezing temperatures. Many locations will experience lows in the mid 20s, while the urban heat holds in the upper 20s to 30 degrees. Thus, the Freeze Warning currently in effect will remain in place through tonight.

The mid/upper level trough axis will pass to the east by tonight while a surface high pressure builds across the mid and lower Mississippi River Valley Thursday morning. In addition, shortwave ridging will build in over the western Great Lakes. All of this will begin to push the coldest air out of Michigan for the late week period. Late April sun angle and fewer clouds for Thursday will help daytime high temperatures recover back into the 50s for much of southeast Michigan. A vort max dropping out of Hudson Bay on the backside of the trough will bring increased low level flow between 20-30 knots. Diurnal mixing depths on Thursday increase to around 2 km which will result in gusty west winds peaking in the afternoon on Thursday. Gusts up to 30 mph will be possible.

The aforementioned surface high pressure will move through the Ohio Valley during the late week period keeping conditions dry for Thursday and Friday. Deep layer west-southwest flow will help temperatures rebound further for Friday. Forecast high temperatures for Friday are in the 60s. Chances for rain increase Friday night and Saturday as northern stream and southern stream jets interact which generates a surface low that moves through the Ohio Valley and sends increased moisture/theta-e into southeast Michigan. Temperatures slightly below normal (mainly in the 50s) for the weekend due to the rain chances for Saturday and then some cooler air in the wake of that system for Sunday. Amplified upper ridging during the early week will bring much warmer temperatures early next week.

MARINE.

The low pressure system that is bringing snow across southern Lake Huron will push off to the east by Wednesday morning. North/northwest winds will switch to a more northerly direction and will persist through the day on Wednesday. A Small Craft Advisory has been issued from late tonight into Wednesday as this northerly fetch leads to a period of building waves over the southern basin of Lake Huron with gusts to around 20 knots. Cold northwest winds tonight will gust to around 25 knots over central and northern lake Huron. High pressure builds across the Ohio Valley tonight through Friday leading to lighter winds.
