.DISCUSSION... Issued at 341 AM CDT Tue Oct 14 2025
A ridge of high pressure settles over the Northland today, and while normally we would be looking at quiet and dry weather, that is not going to happen today. The upper level pattern has a large low pressure system over the southwestern CONUS, feeding moisture and periodic shortwaves in our direction today through at least Wednesday. Today that moisture will be gradually pushing into the Northland, and only then will we finally get some showers into the southwestern portions of the forecast area this afternoon. We currently have some chance to even likely pops by late this afternoon around Brainerd, but considering how dry the sounding from KINL at 00z was, would not be surprised if this moves in a little slower than what we have in the forecast right now. This precipitation will likely not make it to the ground at the onset of precipitation as the dry low level air will only lead to virga. Any accumulations overnight tonight will be light, less than a tenth of an inch, and only over the southern third or so of the forecast area. The warm, moist air advection will continue through Wednesday into Thursday, as the upper level trough pulls out of the southern Rockies and pushes northeast across the plains and pushing into Manitoba on Friday. With this, there will be another push of precipitation moving across the Northland beginning Wednesday night, continuing through Thursday, then tapering off to scattered showers Friday, which linger through the weekend.
While temperatures will remain cool today with the increasing clouds, the warm air advection will bring a warming trend through the rest of the work week, with highs by Friday in the mid 60s to low 70s. Temperatures cool off for the weekend with the upper low now to the northeast and northwest flow bringing cooler air back into the area. High pressure builds back into the area for early next week, keeping temperatures near normal. Precipitation chances should return by the middle of the week, depending on how quickly the next upper level trough pushes into the area. Confidence in the timing of precipitation is quite low at this point, with some pretty large differences between models.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 341 AM CDT Tue Oct 14 2025
A ridge of high pressure building into the area today will cause winds to become generally light at 5 to 10 knots for today, generally out of the north to northeast. Tonight rain shower chances slip in from the southwest, but no lightning or thunder is expected. East winds continue for Wednesday, at generally 5 to 10 knots. Waves through Wednesday night will remain generally 1 foot or less. The high pressure ridge slides off to the east later in the week, allowing winds to pick up out of the south to southeast by Thursday. A warm front will bring another round of showers to most of the lake during the day on Thursday, with precipitation chances lingering through Friday night.
