A Category 4 storm south of Japan will affect the weather for the First Coast and the entire southeastern US.
JACKSONVILLE, Fla. – When looking at long-term forecasts, weather forecasters not only look at what’s happening locally, they also need to look at what’s happening around the world. Similar to predicting the water level for a river, you not only want to know what’s happening in your part of the river, but also upstream.
Because of this, a typhoon that was once in a Category 4 storm south of Japan and west of Guam last week will also play a role in our weather later this week, eventually causing temperatures to drop until next weekend rise.
The storm is making headway into the jet stream south of Alaska this weekend, submerging it. Much like someone snapping a rope and causing waves in it, the storm will cause the jet stream to “tear,” resulting in some significant troughs and ridges later this week.
What does this mean for First Shore?
We will be positioned below one of the crests of these curves in the Jet Stream by the end of the week, which will result in a rise in temperatures. Indeed, according to the CPC 8-14 Day Outlook, above-average temperatures will occur throughout the US Southeast.
This is all thanks largely to a typhoon that formed east of the Philippines earlier this week.
