Fxus63 kdtx 191036 afddtx area forecast discussion national weather service detroit pontiac mi 636 am edt Mon aug 19 2019 Aviation Remnant low level moisture and nocturnal cooling has led to the development of an ifr and lifr stratus fog deck from generally ptk south into portions of metro detroit early this morning. This stratus has been attempting to expand northward toward fnt but appears to be hindered by the iris hills. Diurnal mixing will erode this stratus fog this morning, with the lingering moisture developing a sct to bkn CU field; based in the 3500 to 4000 ft range based on latest model soundings. For dtw... .Fog and low stratus has been meandering in the vicinity of metro early this morning. Can not rule out some of these clouds pushing back into metro early this am. Dtw threshold probabilities * moderate in ceilings at or below 5000 ft today. Prev discussion Issued at 352 am edt Mon aug 19 2019 discussion... ample low-level moisture trapped beneath the nocturnal inversion, aided by last evening's precipitation, has allowed for areas of fog and stratus to begin to develop this morning as high clouds continue to exit to the east. The upper trough axis associated with yesterday's active weather is also moving off to the east, allowing for heights to slowly rebound today. The surface cold front will drop through the northern part of the CWA this morning and gradually wash out, bringing in light northwest flow and drier air. Should still be enough moisture present for a healthy diurnal cumulus field this afternoon, especially across the south where better moisture will linger. Midlevel subsidence and negative vorticity advection will result in weak surface high pressure building in through the day. Highs today in the low 80s with light winds. Lowered pops across the south given the lack of forcing, though some instability looks to leak north of the border and a weak wave passing south of the indiana ohio border may allow for an isolated afternoon shower in lenawee or monroe county. Zonal flow through much of the column will prevent any meaningful modification of the air mass tonight. Lingering moisture across the southern CWA may result in fog again late tonight, especially given

the light flow and mostly clear skies. Warmer air advects in from the west on Tuesday, bringing 850mb temps back up to the upper teens c. As a result, expect slightly higher daytime highs in the mid 80s, possibly upper 80s in metro detroit. Dew points remain elevated near 70 degrees across the south and will lead to a muggy day with heat indices approaching 90 degrees for areas along and south of i-96 696. A convectively-induced low will track into the great lakes late Tuesday night into Wednesday and bring the next chance for showers and storms. Forcing looks diffuse and expect a decent cap in place to keep coverage isolated. A potent midlevel low will drop into the northern great lakes on Wednesday and push a cold front through the region. Still some disagreement between models on timing with the ECMWF a bit slower, but solutions are generally showing a lack of moisture that may lead to just some isolated to widely scattered convection ahead of the front Wednesday afternoon. The front will usher in a much cooler and drier air mass that will take residence over the area for the late week into the weekend. Highs in the 70s and lows in the 50s can be expected with no significant storm systems making an impact. Marine... winds and waves will decrease during the course of the morning as weak high pressure expands across the great lakes, eventually becoming light and variable by afternoon. The high will depart to the east on Tuesday, allowing light south to southeast winds to develop in its wake. A cold front will track across the area on Wednesday. There will be a push of cooler air in the post frontal environment late Wednesday into Thursday, leading to an increase in the north-northwest winds across the lakes.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
