40s return to Minnesota; storms slam the coasts

Minnesota's Tuesday snizzle-fest slowly sputtered to an anticlimactic conclusion.

A tenuous coating of light snow on decks and rooftops melted Tuesday afternoon. The force of our spring equinox sun now enough to penetrate the overcast. Most locations reported less than an inch of snow Tuesday.

What little snow fell on the Weather Lab deck quickly succumb to the start of astronomical spring.

Our slow motion spring continues. The average high in the Twin Cities reaches 45 degrees this week. Temperatures rebound into the 40s across much of Minnesota by Thursday.

Model convergence on weekend system?

Tuesday afternoon's European Centre for Medium-Range Weather Forecasts model run backed way off the notion of heavy snow for the Twin Cities this weekend.

Most models now suggest a quick shot of snow overnight Friday night into Saturday morning. It's still too early to be confident about precip type or placement.

California deluge

The storm that will douse Minnesota Friday night moves ashore in California. The system is being fed by an atmospheric river. The fire hose of tropical moisture streams in all the way from the central Pacific.

Rainfall totals of 4 to 7 inches look likely in some of the burn scar areas.

Flash floods and debris flows from vegetation-stripped burn zones are the big threat over the next 72 hours.

Nor'easter No. 4

The 4th nor'easter in the past three weeks is pounding the East Coast.

Snowfall in the higher elevations northwest of Washington, D.C., could reach a foot.

Heavy snow works northeast from New York and Philadelphia toward Boston over the next 24 hours.

Snowfall totals will likely exceed a foot in much of the northeast. I'm more than OK with our light snizzle Tuesday.
