A very sluggish weather pattern is in place right now with no real change in the pattern expected through this weekend.
A broad upper level trough will remain over the upper Midwest through Sunday, but the amount of lift/forcing with this trough isn’t very strong, and is also fairly disorganized, so what we’re left with is for areas of rain in the Northland, while other areas get very little rain at all. Winds aloft are very weak, however, and that combined with a juicy air mass overhead could produce pockets of heavy rainfall, but it’s nearly impossible to predict what areas of the Northland would be impacted by these pockets of heavy rainfall since they will likely be pretty isolated.

So far the most significant rains have been confined to western portions of the Northland with little to no rain so far for the North Shore, Twin Ports, eastern Minnesota and northwest Wisconsin.

Lots of juice in the air today with dewpoints across the Northland in the low to mid 60s on this 1st day of October 2021.
PWATS or Precipitable Water is also on the high side especially for this time of year, with values approaching 1.50″ in parts of the Northland late this afternoon. What this means is where it does rain, it could be heavy at times due to all the moisture in the atmosphere.
