DISCUSSION...

An anomalous upper level ridge advancing into central sections of far northern Canada will open the door to the rapid amplification of an Omega Block over the central Contiguous United States for the end of the work week. Upper level high pressure will then stall out and impact the forecast area through Monday of next week. Quite the structure with H3 heights reaching 588 dam over portions of the Lower Peninsula this weekend and +13C 850mb temperatures advecting well into Hudson Bay. Ideal mid Autumn conditions with high temperatures reaching the middle to upper 60s, 5 to 10 degrees above normal, and lows falling into the 40s.

The only weather of significance the next few days will be br and fog chances during the daybreak periods. A better setup for fog will be Friday morning with onshore flow advecting a marine airmass inland. The relatively warm lakes will offer higher dewpoints that combined with weak flow will provide for saturation potential. Surface condensation pressure deficits support fog beginning in the tip of the Thumb tonight before expanding southeastward through all of the area. The fog potential for Saturday morning looks to be the greatest near Lake Erie before expanding westward. Could see a scenario where the Detroit urban heat islands remain just warm enough to dissuade the fog formation. Persistent light easterly wind should bring more fog chances Sunday morning. Will likely add areas of fog in the forecast for tonight/Friday morning and maintain the patchy mention this weekend.

Models suggest the amplitude of the omega will shear off or flatten by Monday. Indications are that a weak cold front could push southward invof Southeast Michigan, however, current data suggests a dominance of anticyclonic flow trajectories that will not favor large scale synoptic ascent. Preference is for a dry forecast through next Wednesday.
