Calm before a late week storm

Good Tuesday, folks. We have a very nice little break taking place across the region, but another storm system targets the region late this week. That looks like a big rain and wind maker for our region as the active 2018 pattern rolls on.

Temps today start around 20 and end in the 40-45 degree range with a mostly sunny sky. Wednesday’s weather looks mainly good with some late clouds moving in. I can’t rule out a light shower Wednesday night, but I’m not too excited about that possibility.

We have a big upper level low slowly working across the region for the second half of the week into the start of the weekend. These systems have a mind of their own because they’re cut off from the main flow.

The theme of the models is the same, but big differences show up in how they handle the actual powerhouse low pressure.

The GFS only gives the chance for some flakes on the backlash moisture, but has a clipper with snow following that up:

The Canadian has much more wraparound snows behind this storm, but does not have the GFS clipper:

The ICON is more in the mindset of the Canadian:

All of this is in an otherwise milder overall pattern across the country. That starts to change later next week as blocking shows back up. That’s likely good news for Christmas week as the pattern trends colder, with some snow chances trying to show up, too.  I’m dreaming of a… Ok, I won’t sing, but I bet you are now.

Have a terrific Tuesday and take care.
