Super El Nino?
The long-range outlook is an enigma wrapped in a riddle but every now and then Mother Nature gives off clues. The chance of an El Nino warming event later this year has risen to over 70 percent and this one may be very significant. The amount of warm water in the equatorial Pacific is greater than any time since the record El Nino of 1997-98.
A regular, garden-variety El Nino starts up in the eastern Pacific and moves west. Super El Nino events do the reverse, starting near Australia, then shifting east toward the Americas. That's what's happening in 2014. El Nino often throws a monkey-wrench into global weather, sparking droughts and floods in unusual locations, warming the atmosphere even further. 1998 was the warmest year, worldwide, on record in the 20th century.
Most, but not all, El Nino summers tend to be cooler/wetter in Minnesota, but fall/winter tends to trend warmer & drier. Details in the blog.
A sprinkle is possible this morning as temperatures limp toward 60F. Our slow-motion spring revs into high gear by midweek with T-storms; a few may become severe Thursday with highs near 80F. ECMWF models shows another soaking storm 1 week from today. No need to water anytime soon.
On May 5 I'm happy to report that snow/frost season is over.

- "Know where safe shelters are in public places you frequent like church, the grocery store, or a mall. Spaces under wide, arched roofs are not safe.
- Teach your children to crouch down on the floor, against a wall, with their hands covering the back of their head.
- Understand the difference between a watch & a warning. A watch means conditions are “ripe.” A warning means weather is in action..."
