Discussion
Msas analysis this morning places the center of surface high
pressure at 1026 mb over the ohio river. A surface ridge axis
extends northward into the great lakes with support for high
pressure having shifted to shortwave ridging aloft. A weak vertically
stacked low pressure system is spinning over portions of the mo
river valley. Strong model consensus exists that shows the low
pressure system releasing eastward today while undergoing a
significant amount of weakening. A weak col is noted over lower
michigan during the midday period in response to sheared out cyclonic
vorticity ejecting eastward and diabatic surface heating. This
weakness will help mid-high cloud canopy build persist over the state
today. Difficult to figure what impact this high cloud will have on
temperatures. With little to no lower tropospheric moisture for the
first half of today, preference is to favor mild daytime temperatures
in the lower to middle 50s.

High predictability feature to key off of today and this evening is
aggressive backdoor cold front that is currently pushing due
southward toward lake superior lake huron. Classic shallow cold
front setup with acceleration of the cold front southward due to
rapid transition to anticyclonic flow in the presence of intertial
instability. The cold front is expected to clear the northern thumb
by 21z and through metro detroit between 00-06z. Wind directions
will rapidly flip to the northeast with gusts in the 15 to 25 mph
range. Model trends have supported a lowering of pops both during
the afternoon and evening. Plan views and cross sections suggest a
general lack in system relative isentropic ascent with main
precipitation potential arising merely from differential
increase advection of equivalent potential temperature in the
925-700mb layer. There is some suggestion that a frontal zone may
exist at approximately 600mb, but system relative progs are fairly
clear in showing downglide through that layer. Gut feeling is the
best activity will occur with frontal wave is it rolls through the
northern ohio river valley. Chance pops for rain exist south of
detroit to the ohio border in the 21-03z time window. Expecting quite
a bit of virga, just not sure exactly how much of it will reach the
ground. It remains clear this will be a low QPF event for those that
measure. Very low potential for snow to mix in.

Aggressive surface high pressure will be in control of the region
through the middle of the week. Chilly temperatures are expected
with readings some 7 degrees below normal Monday, some 3 to 7
degrees below normal Tuesday. However, clear skies will make
conditions pleasant.

Southwesterly return flow will ramp up Wednesday allowing
temperatures to respond to around 50 degrees. Warming aloft will
bring steep midlevel lapse rates and chances for nocturnal shower
development Wednesday night. The question for the end of the week is
where will the baroclinic zone set up as flow is forecasted to
become zonal. This will be important as the pattern will favor
active weather precipitation for locations over the great
lakes midwest.

Marine
A cold front will push south across lake huron this afternoon. The
front will be marked with a wind shift to the northeast. Good post
frontal cold air advection will support a period of gusty winds
behind the front, up around 20 knots, persisting to Monday morning.

There is likely to be higher gusts across saginaw bay as the
northeast winds funnel into the bay. The combination of gusty winds
and building waves will support small craft advisory conditions
across lake huron and saginaw bay from late this afternoon through
Monday morning. Strong high pressure will then expands across the
region Monday and will reside through Tuesday. This will support a
gradual decrease in the winds late Monday night into Tuesday.

while there will be an increase in the high clouds Sun morning,
ample low to mid level dry air associated with high pressure
departing toward the mid atlantic will sustain clear skies below 12z
feet through daybreak. The southwest gradient on the back side of
this high will support a light wind through the morning. A cold
front will advance into SRN mi from the north late in the day
Sunday. This front will lead to a rapid wind shift to the northeast,
with a possible short duration of MVFR strato cu. A brief period of
wind gusts over 20 knots following the cold front is also expected
as colder air rushes into the region.

For dtw... The cold front is forecast to pass through metro around
03z Sunday, again leading to a rapid wind shift to the northeast.

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.
