The attached satellite graphic gives analysis for current features that will play in Alabama’s weather over the next several days. Blocking in Atlantic expands/further develops west into the eastern CONUS, while a developing/deepening low comes out of the Eastern Pacific to form a deep low over the West/Rockies.
This will result in an Omega blocking pattern. It is called that because the jetstream flow resembles the Greek letter Omega. This type of pattern tends to slow the progress of weather systems down and leads to a stagnant pattern.
The good news is, it is spring, so these patterns don’t last too long. But if you are under the high for nice weather you will want it to last forever…if you are under the low, you will hope that it quickly moves away so spring can return.
Unfortunately, Alabama will be nuder the low through Friday and maybe into Saturday. But, as I always say: I hate drought, so we will take the rain!
