Mainly Wet - Mix It Up Later?

Hello Again.

With a chance to look at fresh data now that everyone is in bed and the event has started, let's try to unravel some of these mysteries.

WEATHER ADVISORIES TO NOTE:  The National Weather Service has issued a Winter Weather Advisory for Clinton and Shiawassee counties for a wintry mix of precipitation that will be in the area until late morning tomorrow.  The advisory expires at 1 PM tomorrow afternoon.  There will be ongoing snow and freezing rain or sleet.  Basically all modes of winter precipitation are possible in this area.

SO WHAT WILL WE HAVE, RAIN, OR SNOW?  I say both.  Right now, it's rain, and it will stay that way for awhile.  I don't see the temperatures falling below freezing until tomorrow late evening, and by that time the lion's share of precipitation will have worked out of the area.  A surface boundary is stalled literally two counties north.  Anything in the cold sector gets snow or something similar.  We, thankfully are in the warm sector and temperatures support rain.  Now as the boundary gets pushed to the south and we get falling temperatures, expect a changeover to mixed precipitation and then some snow.  I don't foresee a huge accumulation from this, maybe an inch or a touch more.  Here's a look at the current radar composite:

As you can see, not much elbow room between us and that wintry precipitation!

LOOKING AHEAD TO THE WEEKEND:  We get this little bit of disturbance out of here and have a bit of time before the big system shows up on Saturday evening into Sunday.  Right now it's an evolving low way out in southern California and into Baja Mexico.  The next 12 hours should see it cross entirely into the US and then we can get a good look at it, poking and prodding to get a feel for where it's going to go and what it will do.  Forecast models have it tracking thru Texas, Oklahoma, Arkansas and Missouri, ending up on our doorstep late Sunday.  Right now, the data suggests temperatures that support rain.  Sunday night into Monday, as that thing passes by, I see it dragging a cold front that will put us back into snow and falling temperatures.

Here's the forecast for Jackson and vicinity:

Have a great one.  We'll update you as the day progresses.
