Near term (today through tonight)
issued at 233 am edt Sat sep 23 2017

Record-setting warmth again today...

high impact weather potential... None.

Pattern synopsis forecast... Large area of strong high pressure and
dry air is holding in place from southern quebec thru most of the
great lakes region into the ohio valley early this morning...

maintaining unseasonably warm temps and mostly precip-free
conditions across this entire region. Remnants of the MCS that
impacted eastern upper michigan last evening are just exiting that
area... And line of convection that moved thru northern lower
michigan last evening is long gone... Leave dry conditions across our
cwa attm. MCS developed upstream along and north of the warm front
associated with low pressure developing over the northern plains.

Dwpts dropped into the upper 50s and lower 60s in the wake of last
evening's convection. Thus... Little in the way of fog has developed
so far.

As we head into today... The warm front will gradually lift
northward... Allowing surface ridging to reestablish itself across
our entire CWA for today and tonight. Strong subsidence... Dry air
thru the column and a strengthening mid level cap should preclude
additional convective development today and tonight. Latest SPC day
1 convective outlook generally agrees with this notion.

Another hot lake september day is expected across the northwoods.

Several locations will likely match or break MAX temp records again
today. Afternoon highs will range from the upper 80s in eastern
upper michigan to the low to mid 90s for most of northern lower
michigan. Expect another muggy night as temps drop into the 60s and
dwpts hold in the 60s as well.

Records for today:
record (year)
glr 83 (2004)
tvc 90 (1937)
apn 89 (1937)
anj 84 (1936)
htl 88 (1937)
pln 86 (2004)

Short term (Sunday through Monday)
issued at 233 am edt Sat sep 23 2017

String of record breaking temperatures continues...

high impact weather potential: none.

Pattern forecast: no meaningful changes to the large scale pattern
are expected through early next week as troughing remains anchored
over the intermountain west with downstream ridging over the eastern
two thirds of conus. Riding across the ohio valley great lakes
characterized by unseasonably high 500 mb heights from 588-590 dm
for the first few days of autumn. Surface high pressure overhead
combined with limited deep layer moisture should limit much in the
way of precip potential locally.

Primary forecast concerns challenges: warm and humid weather
continues through early next week. High temperatures are expected to
remain as much as 20-25 degrees above normal through Monday. Dew
points varying through the 60s will provide a mid summer-like feel
across northern michigan under partly to mostly sunny skies.

High temperatures both Sunday and Monday are expected to challenge
records at most climate stations. The following are current records
(sun mon):
anj: 88(1892) 83(1908)
glr: 86(2007) 76(1958)
htl: 86(2007) 91(1920)
tvc: 89(2007) 89(1908)
apn: 89(2007) 85(1935)
pln: 87(2007) 80(2007)

Long term (Monday night through Friday)
issued at 233 am edt Sat sep 23 2017
high impact weather potential: minimal.

Upper ridging remains persistent across the region through Monday
night before beginning to break down as an area of low pressure over
the upper mississippi valley ontario and attendant cold front
extending southward into the southern plains will bring increased
cloudiness throughout the day Tuesday and renewed shower chances
Tuesday night through Wednesday. After the cold frontal passage, our
extended summer-like weather will go by the wayside as high
temperatures struggle to rise much above the mid-60s for most on
Wednesday. Even cooler (below normal) for Thursday-Friday with highs
in the upper 50s to low 60s. A more unsettled pattern is anticipated
for the end of the week as well, with occasional showery periods now
out of the question.

Aviation (for the 12z tafs through 12z Sunday morning)
issued at 645 am edt Sat sep 23 2017
vfr conditions are expected today and tonight as strong high
pressure remains firmly in control of the wx across northern lower
michigan. SW winds around 10 kts today will again become
light variable tonight.

Marine
Issued at 233 am edt Sat sep 23 2017
winds and waves will remain below SCA criteria today thru Sunday
night as high pressure holds overhead. Mainly dry wx and
unseasonably warm temps are expected across our entire region thru
Sunday night.

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.
