Vfr conditions to continue through the period as surface high
pressure settles over the great lakes this afternoon. Light
north-northwesterly flow will gradually diminish into the evening
and overnight hours, while a dry column and subtle subsidence will
maintain mostly clear skies. Some high cirrus clouds will move in
late in the period as moisture spills over the ridge axis upstream.

Dtw threshold probabilities
* none.

discussion...

after a chilly start, a long overdue period of spring weather is
shaping up for today through the weekend. Expect dry conditions to
be ensured by high pressure building over the region and
temperatures moderating toward normal values in the upper 50s to
lower 60s Saturday and Sunday. North wind will linger today but will
be much lighter compared to yesterday, and then trend light and
variable over the weekend. The exception will be the usual lake
breeze development and resulting colder afternoon temperatures along
the great lakes shorelines each day.

Moderating temperatures will gain traction today as the low level
thermal through is already east of lower michigan. This, and
considering temperature performance yesterday, expect highs in the
upper 50s across inland areas. The typically warmer interior
locations could touch 60 down through detroit metro, as long as the
wind is not SE from downriver. These afternoon highs will be capped
off by a shallow mixed layer building to only about 900 mb in model
soundings despite just thin cirrus for cloud cover during mid to
late afternoon.

Tonight will be another chilly one, although cirrus coverage is
projected to become meaningful for inhibiting radiational cooling
resulting in no less than partly cloudy sky after midnight. However,
light and variable wind will be in place and low temps will make it
back down to around 30 most locations. This will lead to a repeat
performance Saturday, although the detroit area through downriver
will experience a little more lake breeze cooling both Saturday
and Sunday while interior sections make a run at lower 60s.

The upper air pattern is setting up favorably for the great lakes
with a nearly full latitude ridge extending from central canada to
near the western gulf. This is downstream from a closed low over the
four corners region that is helping establish a slowly progressive
northern stream large scale flow that will allow high pressure to
remain over the great lakes through the weekend. Upper jet energy
will gradually migrate into split flow north of the closed low
allowing long range models to project a short wave trough reaching
northern ontario Tuesday night. This feature is shown to siphon some
moisture from the remains of the southern stream closed low and
bring our next chance of rain Tuesday night into Wednesday of next
week.

Marine...

small craft advisories for the nearshore waters of lake huron from
port austin to harbor beach will remain in effect through this
morning as northwest winds maintain elevated wave action. A weak
pressure gradient will result in light winds. Conditions will remain
dry as a high pressure drifts across the great lakes through the
weekend. Winds will be southerly to start next week as the high
pressure moves east of the great lakes. The next shot at unsettled
weather conditions will be toward the middle of next week.

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.
