We are already halfway through October which means Winter is right around the corner. In what may be a surprise to no-one we are not expecting any snow here in Acadiana this winter but we are expecting some differences from last year's forecast. NOAA or the National Oceanic and Atmospheric Administration has put out their 2020-2021 Winter Outlook so, let's break down what they are expecting and how it affects you.
We have talked about it already before but we are currently in La Nina. What this means is that there is a large amount of cooler than normal water off the coast of South America. This has pretty big implications for our global weather especially as we head into this winter.
Let's first start with temperatures NOAA is expecting warmer than average conditions for the southern half of the United States this winter that is mainly in part due to La Nina and is expected. We will still likely have some cold spells but expecting an overall warmer than normal winter here in Acadiana. Looking at the expected precipitation for the winter NOAA is also calling for below-average or drier conditions here across the Southern US. at this time we do not expect any drought to form here in Louisiana as conditions have been pretty wet so far this year.
Winter, of course, is our severe weather season and with La Nina we do see some changes in our typical low-pressure tracks. Low pressure typically tracks a little bit further north as the jet stream pulls back to the north as well. What this means for us is that we will once again be in warm sectors or in the regions of the systems where we typically see severe weather. This once again is something that is expected for this time of year but, we will have to see if this results in more severe weather over the winter months.
Things will likely change in the coming months but do expect these overall patterns for the upcoming winter. Will keep you up-to-date here on News 15 with the latest forecast.
