Quick Update - We'll See Some Snow!

Hello Again!

Just a quick update to let you know that I have had the chance to look at a bit of weather data and analyze it with the aid of a couple of winter forecasting tools that I had to reinitialize.  Looks like south central Michigan may see snow and accumulating snow.  How much you ask?  Possibly up to 2" up in the north zone (Lansing, St. John's) and perhaps an inch give or take in the south zone (Jackson, Battle Creek, Hillsdale, Adrian).

Data is suggesting if it hasn't already started, it should soon, and should be winding down by about 7 PM.  That being said, be prepared for a slower than normal trip home from work.  We'll advise you of any further changes.

Shades Of Winter - Then Milder...

Good Evening!

As afternoon fades to evening here in Michigan, it's time to take a look at the forecast maps and data and try to make sense out of this coming week.  One deeper dive coming up:

A QUICK NOSEDIVE TO START THE WEEK:  Temperatures are in the 40's around the area right now, don't expect those to stick around for too much longer, as we do have a bit of a frontal boundary coming through.  We'll see the coldest air of the season thus far filtering into Michigan in the next 24 hours or so.  Temperatures will top out just above freezing tomorrow and into Tuesday before our daytime highs recover later on.  Have a look at this graphic, showing the GFS forecast model's idea of temperatures as we head into Tuesday morning around 7 AM:

Temperatures in the 20's with NW winds up to around 10 miles per hour will give us wind chills in the TEENS!  Dress warm for the bus!
In addition to the cold, we'll also have to consider some...

RAIN OR SNOW SHOWERS TO START THE WEEK:  As I stated in my quick look, when the frontal boundary moves through, it will do some lifting of the air that will be enough to kick off some showers and snow showers.  I don't expect much, if any accumulation on road surfaces, but there may be a little bit on grass, and you'll want to use a little extra caution as we'll be cold enough that bridges and overpasses definitely could have some ice form on them.  The best chance for precipitation should be a window from about noon tomorrow through about 9 AM on Tuesday. That being said, here's a look at a future radar picture as forecast by the NAM forecast model.


He thinks we'll be wet not long after morning rush is over, so file that away as a possibility.  You should expect perhaps a touch slower than normal commute home from work tomorrow evening. This forecast map shows you what the Weather Prediction thinks regarding our precipitation totals for the next five days.

Somewhere between a quarter and half inch of liquid precipitation over the work week is forecast by the WPC.
After we get though this stretch, we'll see some...

DRIER, MILDER CONDITIONS LATER THIS WEEK:  Average high this time of year is 47 degrees, so we'll see that in the latter part of the week.  Forecast models are suggesting that we get into mild air again for the weekend, something on the order of almost 60 degrees for Saturday, but I think that's a bit overdone.  Let's call it 54 degrees for the weekend and re-visit that as the week progresses.  Some partial clearing as milder air that's more westerly in nature filters in here, we'll stay with that until the weekend, when our skies cloud up and we ramp up the chances for some showers as the next disturbance works into the area.

Here's a look at the forecast for Jackson and surrounding areas including Rives Junction and Vandercook Lake:



I hope you have a wonderful evening and a good start to the week tomorrow!  Blessings.
