for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...high pressure influence gradually exits the central
great lakes today while the next low pressure system deepens and
takes aim at the ohio valley. showers, with potential for mixed
precipitation, linger into the weekend as larger scale troughing
persists.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

29.8 inch low pressure taking shape over iowa will deepen to 29.6
inches as it tracks to indiana by early evening. the low will 
quickly advance through the northeastern united states on 
thursday. progression of the low and upper level disturbances
rolling across the upper great lakes will result in steady 
increases in northerly winds this evening through thursday. wind 
gusts should eventually exceed gale thresholds for the southern 
two thirds of lake michigan by early thursday morning. the gale
watch was upgraded to a gale warning. 

northerly winds will remain steadily breezy, though below gale 
thresholds, through the day on friday as strong high pressure
around 30.3 inches over ontario drifts toward the hudson bay. 
winds will taper sunday into monday as 30.5 inch high pressure 
builds directly over the open waters. 

persistent northerly winds will allow for the development of a band 
of lake effect precipitation thursday through friday. current 
forecast guidance has shifted that the band more toward the
western half of the lake on thursday, and the center/east half on
friday. low level temperatures will be supportive for mainly 
rain, though some snow could mix in over the northern half of the 
lake. given the deep mixing depth and high water-air temperature
difference, there is an increasing waterspout potential during 
this period.

.synopsis...

30.1 inch high pressure will progress from the upper mississippi 
river valley across the southern open waters through tonight, 
allowing for decreasing west-northwest winds. 29.8 inch low 
pressure will move quickly from the northern great plains into the
ohio river valley on wednesday, quickly advancing into the 
northeastern united states on thursday. progression of the low 
will result in steady increases in northerly winds wednesday 
evening through thursday, with gusts eventually approaching or 
exceeding gale thresholds thursday morning & afternoon as 30.4
inch high pressure builds into the canadian great plains. best 
potential for gales will be over the southern half of the waters, 
where a gale watch is now in effect between 6 am and 6 pm cst 
thursday. northerly winds will remain steadily breezy--- though 
below gale thresholds---through the day on friday as the 
aforementioned high nudges east toward the hudson bay. winds will 
taper sunday into monday as 30.2 inch high pressure builds 
directly over the open waters. 

persistent northerly winds will allow for the development of a band 
of lake effect precipitation thursday through friday. current 
forecast guidance suggests that the band will be positioned 
somewhere from the center to eastern half of the lake, though any 
small changes in prevailing wind direction could result in westward 
shifts. will continue to provide updates in coming forecasts. low 
level temperatures will be supportive for mainly rain, though some 
snow could mix in over the northern half of the lake. thunderstorm & 
waterspout potential is low within the lake effect precip band.
