Duluth National Weather Service

There is a straightforward, logical scientific explanation why many storms seem to weaken or "split" while passing over Duluth/Superior.

Just because it's not raining doesn't mean the lightning threat is over - the 30-30 Rule could, in reality, save your life.

The potential for serious flash flooding has been underestimated by FEMA, and more properties than we thought across the Northland are vulnerable to increasingly heavy rain

The Twin Ports just set a new all-time winter snowfall record: more than 138" and the snow isn't over just yet. The freezing rain is over but more light snow will fall today and tonight.

You just endured - survived - enjoyed the snowiest winter since accurate weather records were first started in Duluth back in 1885. Today will bring high winds, serious icing and a changeover back to snow, with heaviest accumulation north and west of the Twin Ports.

High winds and rain freezing on contact may coat trees and highways with an icy coating today, before a changeover to snow tonight and Friday that should push the Twin Ports to a new, all-time snowfall record for the winter.

Welcome to a crazy week of weather whiplash with rapidly melting snow up north and fire weather in the south. Serious flooding is already taking place across the Northland as a near-record amount of water in the snowpack is flushed into streets and streams.

Another foot of snow and the Twin Ports will officially be enjoying the 5th snowiest winter on record. We will get closer to that mark today and Friday, with another 4-8" for most of us - a potential for a foot of snow for portions of the Northland.

It's already the 9th snowiest winter on record for the Twin Ports, and more snow is on the way for Thursday and Friday - probably plowable, not crippling, but the snow just keeps piling up in the Northland.

We saw an entire winter's worth of snow by March 1. Just looking at the statistics, we have another 25" of snow to go before warm fronts. That puts this winter in the history books.

Predicting spring flooding is as much an art as it is a science. Snow cover is higher than average, with 5-8" of liquid water trapped in all that snow. If we see heavy rain and rapid warming in March and April we may see significant river and stream flooding later this spring. If you've had flooding issues in the past you should stay alert and up to date with the latest NWS flood outlook
