Friday, Dec. 10 for Muskegon, MI

A brief break in the snow tomorrow before another system brings more precipitation early week. The high temperature tomorrow will only be in the mid 30's with a low in the upper 20's. Windy conditions from a low pressure passing to the north will be possible in the early morning hours. In addition there is a brief chance for early morning snow before becoming mostly cloudy in the afternoon. Snow then returns again over the weekend as another surface low moves into the Great Lakes region.

Forecast for December 9 2010

Slight chance of snow in the evening hours with small accumulation.  Dew points should drop during the morning hours allowing the temperatures to drop below twenty.  After this period of clearing a small weather system will move in picking up winds to about 20 knots.  And in these cloudy, windy, conditions the temperature will not exceed the freezing point.

Week of Dec 6, 2010, Muskegon, Mi

Currently a closed low positioned over Maine is causing wind vectors and surface differential temps to maintain a lake-effect setup. This effect will be strong at times with accumulation rates of up to an inch per hour in the harbor and SE coastal areas. Snowfall amounts exceeding a foot are possible in localized areas through Tuesday morning. As this low lingers over the eastern shore, flow in the region will have only a short time to take an anticyclonic component and the lower level moisture will decrease due to cold, dry advection from the north, the decrease in lake to air temp differential will degrade the lake effect potential Tuesday afternoon into Wednesday, allowing for momentary clear skies. Late Thursday another clipper moves into the area with associated properties, expected only to bring light snow through Friday and snowfall rates will increase for the weekend in the northern part of the forecast area.

Muskegon Mi, December 3 2010

As the wind direction changes from WNW to NNW Friday, sky cover will diminish, the potential for lake effect snow diminishes with the change of the wind after the passing of an upper level shortwave. Flow will briefly become anticyclonic behind this system and ahead of the next system which moves into the area late Friday. Current models place the left exit region of the jet to the southwest of the forecast area, reducing POPS in the northern part of the state and increasing precipitation potential in the southern portion of the state. Lake effect conditions resume Friday evening with the onset of cyclonic flow. The difference in temperature from the lake surface to the air exceeds the 13 degree critical difference, fetch is substantial, exceeding 160km with wind vectors from the northwest, however, with little moisture in the column and decreasing relative humidity expect only light flurries on either side of the dry slot Friday.

Muskegon, MI December 2, 2010

Cold temperates continue as the chance for lake effect show drops. The high temperature tomorrow will be in the low 30's with a low temperature in the mid to upper 20's as the area is stuck under cloud cover. Breezy westerly wind conditions tomorrow as a low pressure system in Canada continues to move toward the Atlantic Ocean. Although not as good as today, there is still a chance for lake effect snow tomorrow with new accumulations around 2 inches. Falling snow and windy conditions may create hazardous whiteout conditions at times during the day tomorrow.
