PREV DISCUSSION. Issued at 324 PM EST Thu Mar 4 2021

DISCUSSION .

Mid level northwest flow will continue to govern conditions across southeast Michigan over the next 72 hours, as the western expanse of height falls associated with a closed low over New Foundland remain fixated over the region. Coldest daytime conditions noted presently, as gradual height falls continue above prevailing low level north- northeast flow. A healthy radiational cooling environment will emerge tonight as lingering low stratus fades with the loss of daytime heating, offering an extended window of clear sky atop a diminishing gradient within encroaching surface ridging. Lows tonight mainly in the teens. Standard diurnal moderation of this colder resident thermal profile Friday given the high degree of insolation and no real advective process. This translates into highs right around average.

Strengthening low level anticylone maintained beneath prevailing northwest flow ensures benign weather conditions throughout the weekend period. Sunday the warmer day of the two, as a building upper height field supplements full insolation to net 5 to 7 degrees of warming across the lowest 900 mb. Window for meaningful warm air advection exists Monday depending on frontal timing and extent of associated cloud/pcpn potential tied to a northern stream shortwave projected to track through the northern great lakes. Regardless, the underlying pattern of generally higher upper heights with a transition toward mid level southwest flow suggets above average warmth will define conditions throughout much of next week. This pattern shift may also introduce a more energetic southern stream, offering greater precipitation potential by Wed-Thu.

MARINE .

A blocked upper air pattern over eastern North America keeps the persistent northwest flow in place through the late week as low pressure hovers over far eastern Canada. Wind speeds around 15 to 25 kt continue through tonight into early Friday which keeps wave activity elevated over the southern basin of Lake Huron. Small Craft Advisories remain in effect for the nearshore zones due to the waves. High pressure continues building into the northern and western Great Lakes tonight and strengthens the existing pressure gradient. Northwest gales subsequently become increasingly likely for northern/central Lake Huron on Friday afternoon and evening, and a Gale Warning has been issued. Wind strength then eases heading into the weekend as the high pressure drifts eastward. Dry conditions prevail through the period due to this high.

DTX WATCHES/WARNINGS/ADVISORIES. MI . NONE. Lake Huron . Small Craft Advisory until 4 PM EST Saturday for LHZ421-441>443.

Gale Warning from 2 PM Friday to midnight EST Friday night for LHZ361>363.
