“Spring is nature’s way of saying, ‘Let’s Party!’”— Robin Williams
The sun’s rays hover directly over the equator at 4:58 p.m. CDT Wednesday afternoon. That marks the start of astronomical spring in the northern hemisphere.
At noon Wednesday, the sun will hover about 45-degrees above the horizon in the Twin Cities. The sun climbs higher in the sky each day for the next three months.
It reaches peak elevation about 68.5 degrees above the noon horizon on June 21. The higher sun angle and intensity and longer daylight drive warmer weather patterns over the next six months.
A rare supermoon on the equinox happens Wednesday night.

Red River later
Flooding generally works from south to north as spring moves in. There’s still plenty of snow on the ground in the Red River Valley. That will mean a later crest with moderate to major flooding likely in places like Fargo and Grand Forks, N.D.

Pushing the season up north
A sure sign spring weather has arrived! Well if you're a hardy northern Minnesotan 😎. Had to do a double take this morning when I saw a figure out on #lakesuperior.
