Concerned about freezing rain potential

Rain in the forecast tomorrow night could lead to slick roads as ground temperatures are still below freezing.

So I love the snow, but don't care too much for the cold.  I know it's hard to have the snow without the cold, but the cold causes a lot of problems.  One of those problems we can run into after a period of deep cold or prolonged cold is that of freezing rain.

Now traditionally freezing rain happens when you get a shallow pocket of freezing temperatures just above the surface with warmer air above it. That however is not the only set up which can cause It.  If the ground is frozen, and I mean seriously cold, it doesn't matter the air temperature the rain will freeze on impact.  

So here's the set up for tomorrow.  Air temperatures are likely going into the mid 40s.  We've still got the small problem of the snow pack to melt off, not to mention a lot of ice that formed from all the rain on Sunday.  I'm not sure if one day of mild air and some filtered sunshine is going to be enough to warm the ground temperature above freezing.  The problem is that rain is looking like it will move back into the area late Thursday and Early Friday.    This is the NAM future radar for 10:00 pm tomorrow.


 

 

And this is for 2:00 AM Friday.  

 

So as you can see we will have a few scattered showers in the region.  The big thing to watch for tomorrow is how much we warm up the ground.  If there is still some snow and ice on the ground tomorrow night, we could have some trouble.  Be on the look out tomorrow and early Friday for the possibility of more slick roads and sidewalks.   Hopefully it won't be a big deal, but I don't want another freezing rain event to sneak up on us like it did a week ago.  Until next time, take care.
