Area Forecast Discussion National Weather Service Detroit/Pontiac MI 1200 AM EDT Fri Apr 3 2020

AVIATION.

Strongly anticyclonic flow in the sfc-725mb layer has allowed surface ridge axis to build into Southeast Michigan. A very dry airmass is now in place with precipitable water at less than .20 inch. Nil moisture will support high stability through Friday. Enough high cloud spilling down into the Great Lakes to carry a SCT250 group. Light northeasterly or variable wind overnight.

DTW THRESHOLD PROBABILITIES .

* None.

PREV DISCUSSION. Issued at 325 PM EDT Thu Apr 2 2020

DISCUSSION .

Slow evolving upper level pattern with pseudo Omega Block as southeast Michigan resides underneath the ridge over the next couple of days. Good subsidence/drying in the mid levels, as 850-700 mb dew pt depressions increase to 30+ C. With the surface high in place tonight, possibly enough shallow/surface moisture for radiation fog. Will add patchy fog to the forecast, but the way dew pts have come down this afternoon, confidence is low. Mid level dry axis looks to hold right through at least Saturday morning, with just slight weakening/moistening per 12z NAM.

850 mb temps around 2 C early this evening, warming to 4 C tomorrow evening favors highs in the lower 60s/around 60 degrees tomorrow, with even warmer readings possible for Saturday as 850 mb reach 5 C ahead weakening cold front. However, the increasing clouds and possible showers by day's end will likely cause maxes to come up short (around 60), as the weak cold front slips through Saturday evening. Bulk of upper level forcing slides through the northern Great Lakes, and with the lack of instability noted, prefer to hold on to just chance pops vs the likely pops suggested by our local probabilistic guidance.

Westerly upper level confluent flow will allow sprawling surface high pressure to return to the Great Lakes region on Sunday, with return flow and increasing clouds for Monday. As it stands now, 12z Euro struggles to get the active warm front north into Lower Michigan Monday night, as pronounced surface ridging builds down from Ontario into Tuesday. However, a piece of upper level energy breaks out of the northern Rockies and could potentially produce showers and even possible thunderstorms in the Tuesday-Wednesday time period, but the Euro has backed off on the instability/capes as well.

MARINE .

High pressure over the Great Lakes will maintain quiet marine conditions with light winds and low waves through the rest of today and into tomorrow. Winds will turn out of the south Friday night into Saturday with the passing of the high pressure to the east with an approaching weak low pressure system and cold front from the west. Front will bring a narrow line showers with winds remaining light while winds shift back to northerly Saturday evening. High pressure brings continued favorable marine conditions Sunday into early next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
