Snowfall for February was There have only been two other winter seasons and that have had or more inches of snow. Through February 25th, the winter season was warmer and wetter than normal but had below normal snowfall at both Fort Wayne and South Bend as a weak to moderate La Nina episode was occuring.
Like the previous winter, the winter proves why you cannot use forecasts of precipitation to imply potential snowfall amounts. The average temperature was 6. This puts the winter season average temperature 4. Precipitation was also above normal for both December and January 1. So far, February has featured below normal precipitation 0. For the winter season, precipitation was above normal by 1.
Snowfall was below normal for December 1. The seasonal snowfall total as of February 25th was The winter season average was 5. Precipitation was also above normal for both December 0. February so far has featured below normal precipitation 0.
While precipitation was above normal, snowfall was below normal for December and February and above normal in January. Snowfall was So if La Nina conditions were occurring during each of the last two winters, why is this winter so drastically different from last winter?
This has been the cause with the current winter with the cold air bottled up in northern Canada. Last winter the AO and NAO were in a negative phase which allowed the cold air to infiltrate the region and cause more snowfall instead of liquid precipitation. Please Contact Us.

All forecast methods try to incorporate the effects of ocean-atmosphere interactions within the climate system. The exchange and processing of the data are carried out under programmes coordinated by the WMO.
It is based on contributions from the leading centres around the world monitoring and predicting this phenomenon and expert consensus facilitated by WMO and IRI. Skip to main content. Sea surface temperatures in the eastern-central Pacific are predicted to be below-average to average during September-November , in the range of For October-December , they are predicted to range from Full September Update.
Past Updates. This subsurface water provides a source for the surface, and it has been intensifying in recent weeks. Water temperatures in the top meters 2, feet of the tropical Pacific Ocean compared to the average in late summer NOAA Climate. Over the past month, the low-level winds near the equator, which usually blow from east to west the trade winds , were stronger than average, as were the west-to-east winds high up in the atmosphere.
These signs, along with more rain than average over Indonesia and less in the central Pacific, tell us that the Walker circulation is juiced up. Earlier posts are September , November , and November Anomalies are calculated with respect to year base periods updated every 5 years see here for a description. Over the contiguous United States, the average location of the jet stream shifts northward. The southern tier of the country is often drier and warmer than average. Till next time!
What's your point, aside from being needlessly condescending? No one's forcing you to accept their analysis and forecast.
No one's forcing you to somehow abide by it, to live your life according to it. So why bother commenting? Take it or leave it. Actually, better yet, suppose you enlighten all of us with YOUR presumably superior analysis and forecast?
Maybe we could have a contest, whereafter I'll make a donation to your favorite charity should your forecast prove superior after an impartial, third-party, post-season analysis. I would venture to state that the region from Quepos south to about Drake Bay will experience a drier and warmer weather pattern. I would expect to to begin in late October and last to about June Second question: Will the La-palma volcanic plumes have any susbtantial impact on the 3. I realize volcanic forcing can have different manifestations regionally and internationally but the pictures from the Island over the last 4 weeks are indicative of some impact here and there.
While I can't speak to this specifically, I do track the weather of the western Sahel. Typically the rainy season doesn't arrive until the E Atlantic waters reach 29C. Therefore the regional cooling may make for a drier season. Great question though I look forward to NOAAs response. Lol, please excuse us if we are not jumping for joy in California. Three out of the last four La Ninas. We are at the breaking point and I fear what is in store for us if we have another year like last year.
Changes in the ocean impact the atmosphere and climate patterns around the globe. In turn, changes in the atmosphere impact the ocean temperatures and currents. Then, easterly trade winds strengthen, cold upwelling off the west coast of South America and along the equator intensifies, and sea-surface temperatures SSTs drop below normal. Both terms refer to large-scale changes in sea-surface temperature across the central and eastern tropical Pacific.

These events typically continued into the following spring. Some episodes may persist for as long as two years.
