Near term (today and tonight)
issued at 144 am edt Tue mar 26 2019
high impact weather: none.

Pattern synopsis and forecast:
all quiet again out there early this morning. High pressure was
working into the western great lakes with a very dry wnw NW flow
holding firm over NRN michigan (pwats < 0.15"). There was not a
cloud in sight and winds at the sfc and just aloft were weakening
with time. This was resulting in increasingly better radiational
cooling conditions. Temperatures were in the mid teens to low 20s,
but am expecting a quicker fall toward daybreak as winds go
calm near calm. Am expecting temperatures to bottom out in the 10f
to 15f most areas, with lower 20s to mid 20s in some coastal areas.

Another 24 hrs of very quiet weather. A shallow mid level ridge will
move in over NRN michigan today, as the sfc high pressure moves
overhead this morning, then into the eastern great lakes late this
afternoon. Pwats remain less than 0.25", increasing a little, due to
some high level cloud arriving late today. Winds go light by
daybreak, then back out of the SW today. That's about it for today.

Highs will get into the upper 30s in eastern upper and 40f to 45f in
nrn lower. The mid level ridge presses east tonight, making way for
a weak shortwave trough tonight, while the sfc high moves off to the
eastern conus. This shortwave trough and increasing southerly flow
will bring in some added upper level clouds this evening, then some
possible low to mid level clouds overnight for mainly NRN lake
michigan and eastern upper, when pwats increase to around 0.40"
there. However, still no precipitation expected. Lows tonight will
not be as cool under this scenario, with readings in the lower half
of the 20s most areas.

Short term (Wednesday through Thursday)
issued at 144 am edt Tue mar 26 2019
high impact weather potential: none.

Pattern synopsis forecast: surface high pressure will gradually
press eastward tonight into Wednesday allowing warm air and moisture
advection to ramp up ahead of the next approaching system. Deepening
low pressure is expected to track from southern saskatchewan
manitoba to near james bay Wednesday night into Thursday, which will
drag a cold front from northwest to southeast across northern
michigan during the day Thursday.

Primary forecast concerns challenges: moderating temperatures.

Precipitation chances late Wednesday through Thursday.

Little in the way of sensible weather is expected through much of
the day Wednesday with the only exception coming across eastern
upper and the tip of the mitt as isentropic ascent increases in
conjunction with a weak shortwave crossing the region. Limited deep
layer moisture will limit the overall rain shower coverage as low
pops gradually expand southward across the remainder of northern
lower Wednesday night through midday Thursday in conjunction with
the aforementioned frontal boundary sagging southward.

High temperatures Wednesday afternoon topping out in the mid-40s
north of the bridge to the upper 40s-low 50s across northern lower.

Similar midday high temperatures Thursday ahead of the frontal
passage before temperatures gradually cool Thursday afternoon.

Long term (Thursday night through Monday)
issued at 144 am edt Tue mar 26 2019
high impact weather potential: minimal.

High pressure settles in across the region late Thursday through
Friday before attention turns to potential low pressure development
that's expected to eject lee of the rockies before trekking east-
northeastward Friday night into Saturday. This system has the
potential for a more widespread precipitation event across northern
michigan, but low confidence in precipitation type and amounts
continues given disagreement with respect to the overall strength
and track of the system. Beyond that system, cooler air brief dives
into the region... Perhaps bringing a bit of lake effect development
to the area on Sunday.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 144 am edt Tue mar 26 2019
high pressure overhead will move over to the eastern CONUS late
Tuesday night. Dry air will remain in place withVFR conditions over
the entire TAF period. Dry air will be in place for plentiful
sunshine today and just some increased higher level clouds tonight.

The pressure gradient starts to tighten out ahead of a warm front
working into the plains, but no significant gusting is expected.

There could however, be some low end llws developing late Tuesday
night, but confidence is not high enough to include in the forecast
attm. No precipitation.

Marine
Issued at 144 am edt Tue mar 26 2019
high pressure overhead will move off the atlantic coast by Wednesday
night, with NRN michigan within a tightening pressure gradient.

Gusty, advisory level southerly winds and the next chance of rain
develop Wednesday into Wednesday night over most nearshore waters.

This will occur out ahead of an advancing cold front that crosses
Thursday, and switches winds out of the nw, where there is also a
possibility of additional advisory level winds in some areas.

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.
