Winter Weather Advisory

For Muskegon, Ottawa, Allegan, Van Buren and Kalamazoo Counties

A Winter Weather Advisory is in effect from 8 am this Friday until 4 am Saturday. Everyone should see some snow during the day. It may not be snowing in the early morning, but the coverage of snow will increase in the midday/afternoon. Snowfall in the white colored counties on the above map will be 1-3” total through Saturday morning. In the purple counties, we should see up to 3-5” of snowfall.

Temperatures will stay a little below freezing all day and snow will stick to lesser-traveled side streets and rural roads and even on the main roads and expressways at times, especially in the purple counties. Driveways, parking lots and sidewalks will have slippery spots.

Here’s a map showing the % chance of 2” of snow today/tonight, with the highest chance in the lakeshore counties and Kalamazoo County and the lowest chance from Alma up to Mt. Pleasant and Clare.

We’ve had 8 days in a row with temperatures in the 20s. The cold pattern has resulted in ice forming on area rivers. We’ll be monitoring river gauge stations as ice jams are possible and they may cause fluctuations in river water levels. Fortunately, no big storms (heavy rain) are expected in the next week.

The latest 8-14 day outlook continues the cooler than average pattern for the next 2 weeks.

Here’s the latest Grand Rapids National Weather Service Forecast Discussion.

This map shows areas still under a Red Flag Warning. The good news is that winds should generally be lighter over the next couple days in most areas. However that are local places (high mountain areas and mountain passes) where there are still strong winds. Check out how variable the winds have been overnight in southern California:

At the top, the wind at 11 pm local time at LAX (Los Angeles Intl. Airport) was calm. However the wind at Chilao was northeast at 37 mph with a peak gust of 63 mph. At Ontario CA, the wind was 36 mph with a peak gust of 58 mph and a relative humidity of just 10%. Most of the current fire areas should see winds of 10-20 mph this Friday.

From Dr. Ryan Maue on facebook: “100% of Santa Ana Wind event fires in Southern California are "human caused" and have little to do with climate change. Instead, acres burned - dependent upon wind intensity and the number of fires ignited, e.g., arson, powerlines, accidents, etc.”

The worst wildfires are started by people. Human-triggered California wildfires more severe than natural fires. Nearly 85 percent* of wildland fires in the United States are caused by humans.

Here’s current reservior levels in California. Most reservoirs are near or a little above their historic average levels for January.

This winter, southern California has been very dry and northern California has been very wet. Eureka in northwest California has had 26.27” of rain since October 1, compared to an average of 17.37” for that period. San Francisco has had 8.68” of rain since October 1 and that’s 0.55” above average for that period. BTW, San Francisco tied a daily record high temperature yesterday (Thu.) at 71 degrees. That reading was also reached on 1/9/1962.
