Area Forecast Discussion National Weather Service Detroit/Pontiac MI 701 PM EDT Fri Jul 3 2020

AVIATION.

Diurnal convection associated with lake breeze boundary interactions will linger for an hour or so into the forecast, but avoid terminals and just provide an hour or two of lower VFR cigs at times. Do not expect a repeat of isolated convection on Saturday as high pressure builds back into the area. This will lead to mainly clear conditions and light northeast flow peaking 5-10 knots in the afternoon.

DTW THRESHOLD PROBABILITIES .

* Low for ceilings of 5000 feet or less through 01z or so.

PREV DISCUSSION. Issued at 343 PM EDT Fri Jul 3 2020

DISCUSSION .

At the forefront is the possible development of convection this afternoon as a mid level wave dropping south through lower MI provides a backdrop for lake breezes to initiate storms. 12Z DTX sounding shows a very warm and fairly dry airmass although moisture has been increasing over the last couple days with PWATs up to 1.2 inches now and sfc dewpoints in the mid 60s. Convergence along lake breezes will utilize this moisture while the mid level wave and strong diurnal heating will attempt to break the cap with up to 2500 J/kg SBCAPE per 18Z SPC mesoanalysis. With the lack of strong support from CAMS in generating storms, will continue to message isolated storms possible this afternoon for a few hours mainly along these lake breezes as they move well inland.

Moving forward, there will be some adjustments to the longwave pattern that had been blocked for several days, but it won't be enough to break us out of the current heat wave we're experiencing. The amplification to the pattern will be muted some as the deep west coast trough pulls back north toward Canada and a series of waves works across southern Canada, though keeping mainly north of the Great Lakes at least through the weekend. This retreat will allow the subtropical ridge to spread across most of the southern states keeping the warm pattern over the conus going. Meanwhile, the upper level ridge axis over the Plains will release eastward, crossing MI Monday. Though the series of waves will slowly suppress heights locally, flow will become more westerly which will continue to advect warm air into the region keeping the potential for 90 degree days going through the forecast. Some indications for one of these stronger waves to cause 588+dam heights to build back into the region mid week which could bring temps into mid 90s. West/Southwesterly return flow will bring increasing moisture and thus humidity next week as well. Precipitation chances return Tuesday with low chances nearly each day as shortwaves track closer to the area.

MARINE .

A ridge of high pressure remains firmly over the Great Lakes region and will continue to hold through the weekend. Favorable marine conditions continue through the beginning of next week. Mainly dry conditions will prevail, with only a slight chance to see some pop up thunderstorms this afternoon/evening, confined to the nearshore and locations inland.

DTX WATCHES/WARNINGS/ADVISORIES. MI . NONE. Lake Huron . NONE. Lake St Clair . NONE. Michigan waters of Lake Erie . NONE.

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.
