The US autumn is off to a warm start. The past several weeks have had an unusual amount of above average temperatures. Most of the country was slightly above average last week. The actual temperatures show nothing is hot, just above average for this time of year. The actual temperatures show that the temperatures are [...]
Going to show the maps for the Oct 2nd and Oct 9th this week as the NCDC was kinda slow in releasing the information. As I have mentioned before, summertime is not a period for large temperature anomaly and that the other times of year had much stronger signals. Sep 25th showed some of that, [...]
The cooler than average temperatures in the western part of the country that have been yearly trend are in for a huge reversal next week though as news of record breaking temperatures has been making the rounds. This is going to get worse as a very strong La Nina is cooling the ocean off the coast of California down. This causes warmer and drier weather from California and the regions east of it.
Last week showed that most of the country was cooler than average and this week the reverse is true. The northern part of the country had the cooler weather while a lot of the southern (especially central) portions were warmer than average. Overall this is a week that would contribute to an above average temperature [...]
This week would be a good time to show the difference between the anomaly map and the actual temperature map. I like this week for that because the anomaly was cool across most of the country while the actual temperature still fairly warm. That makes a good contrast between the cooler than average temperatures that are still warm overall.
As the US heads towards fall the normal behavior is increased temperature anomaly across the country. One thing I hope these weekly updates will show is just how normal temperature anomalies are in the world. As the fall progresses into winter it will be clear that a single warm week in the autumn can contribute [...]
The weekly anomaly map for the US was minimal. The northwest continues the general behavior of cooler than normal temperature. The southeast which has had a warmer than normal year is much closer to the normal for this time of year now. The rest of the country is mostly near average with a scattering of [...]
