Sloppy snow event still lurking this weekend

The maps still look like March this weekend. Yes, it will be milder. But those milder temperatures come with a sloppy, snowy price tag.

The biggest wild card meteorologists are watching in the inbound weekend weather system? Where will the 850-millibar 0-degree isotherm set up? That's usually a very good indicator of the rain-snow line in winter storms in Minnesota.

The latest model runs favor that rain-snow line setting up just southeast of the Twin Cities Saturday. Here's a map only weather geeks would appreciate. I've circled the 0-degree isotherm on this 850-millibar level map for 6 p.m. CST Saturday from NOAA's GFS model.

You can see how close that line is to the Twin Cities. A bump just 50-miles north would produce changes in precip type in the Twin Cities area. That's why temperature is the biggest wildcard now.

We still have 4 days until the bulk of the storm hits. Watch for changes.

Almost Average

Temperatures stagger back closer to average the next few days.

Flood Threat

Here's a good piece on just how local flood forecasters assess water content in all that snow.

Stay tuned.
