You could be feeling a little deja vu this Winter. Forecasters predict this winter will be 'very' cold and snowy, much like last year. La Nina may cause the two different Winters to be so similar.
This past winter when the Bluegrass dealt with bitter cold temperatures and numerous snow fall events, we were under the influence of La Nina.
"Right now it looks like deja vu all over again," says NASA Climatologist Bill Patzert.
"Looking back over the last eight months we've definitely had weather whiplash and weather mayhem and much of this was due to the presence of La Nina," adds Patzert.
La Nina occurs when water temperatures in the Pacific Ocean near the Equator dramatically cool. La Nina pushed the jet stream over the U.S. to the north and made regular weather patterns more extreme. Snowstorms pounded the north and spring rains flooded the Midwest while Texas was kept bone dry. It's not clear if climate change is having an impact on La Nina events. They generally occur every 3 to 5 years, not back to back.
"At this point the trade winds across the pacific are very strong, temperatures at the equator are starting to drop and that really is the footprint of La Nina. All the smart money is on a double bounce for La Nina," says Patzert.
If there's any good news experts say this La Nina should be weaker than the last, a shorter but still unwelcome encore.
