Discussion
High temperature records will be in jeopardy once again today,
especially in the flint to tri cities region as interior sections of
lower michigan remain capable of highs in the lower to mid 90s.

These readings, along with surface dewpoint in the mid to upper 60s
will produce another round of heat index in the mid to upper 90s for
a few hours during mid to late afternoon. These readings are again
short of the 100 degree threshold for heat advisory headlines but
remain notable for the time of year and for occurring during the
weekend with so much outdoor activity. The slightly cooler locations
near the shorelines will also make another run at 90, especially
metro detroit with a little less influence from lake erie. Surface
high pressure that has been oriented southwest to northeast and
centered over lake erie will shift a little more over lower michigan
during the day. This will provide more of a light and variable wind
or a later developing southeast component to allow a longer period
of surface heating before weak lake influence can occur.

Mesoscale cam solutions, mainly just the hrrr, have a few specks of
convective activity again this afternoon. The same was true in last
night's runs for yesterday but with considerable uncertainty on
location. Prefer to monitor satellite trends again through the day to
pinpoint favorable locations for a possible late day shower or
thunderstorm, assuming similarly capped low levels can be overcome by
daytime heating alone.

The mid summer heat wave will continue Sunday through early next
week with a degree or two of cooling expected to occur each day.

This will be due to the core of the upper level ridge sliding
eastward along the atlantic coast as the long wave pattern begins
some adjustment from strong amplification over the last few days.

Still, we are looking at record or near record highs again in the
lower to mid 90s Sunday, lower 90s Monday, and upper 80s Tuesday.

The Tuesday numbers could also be revised upward in later forecasts
depending on cloud cover prior to the arrival of the next cold front
due Tuesday night into Wednesday. This frontal passage will bring
the next organized chance of showers and thunderstorms along with
sharply cooler temperatures. Readings are projected to be limited to
highs in the lower half of the 60s by Friday into next weekend.

Marine
Extended stretch of very warm and humid conditions will exist
through the weekend as the region remains under the influence of
strong upper ridging. This pattern will support light winds - under
15 knots - and low waves during this time. These conditions will
persist into early next week. A cold front crossing the central great
lakes Tuesday night will bring a low chance of shower and
thunderstorm activity, along with winds shifting to the west and
increasing to around 15 knots.

upper ridge will remain anchored over the area, providing nearly
calm wind conditions (outside late day lake breeze considerations)
and mainly clear skies. The warm, humid airmass associated with the
ridge will allow for some patchy fog development overnight
with MVFR to perhaps a brief period of ifr vsbys near sunrise,
mainly dtw yip ptk.

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.
