Marine Weather and Tide Forecast for Dennison, MN

DISCUSSION
Issued at 1254 PM CST Fri Nov 6 2026

Rest of Today into Tonight... After seeing the first freeze of the season for the core Twin Cities metro this morning we will see a gradual warming period. Despite being much colder today than what we have seen recently, this is actual right about normal for this time of year. The normal high for today at MSP is 47 and the normal now is 32, so only a few degrees off of what we are seeing today. Tonight will be another cooler night and will depend on how the clouds evolve. Fairly confidence we will see clouds spread across western Minnesota helping limit radiative cooling. To the east though this cloud cover gets less certain and we will see more radiative cooling and there looks to be a push of some CAA across Wisconsin. So it will be this area with the coldest temperatures tonight.

Saturday into next week... Overall this looks like a fairly dry period with the only chance in the main deterministic global models being a possible Alberta Clipper late Wed into Thursday.
Not seeing much in the NBM right now through, as this is not as consistently shown within the ensemble solutions. This keeps the NBM based long term forecast dry. We had such a wet start to the month though that we are at 800 percent or higher month to date on precipitation at our STC and MSP climate sites.
To put this another way, we would still be above normal if we saw no additional rain or snow at our STC and MSP climate stations for the rest of the month. Past the dry part of the forecast the other key message will be a return to above normal temperatures. After Friday's taste of what normal November temperatures are like we will warm back to above normal. Mostly neutral to warm air advection through mid week before the clipper chance. After that we could see another cooler, closer to normal, period late next week. However another rebound still looks likely so this next round of cold air does not look like it will be the one the makes to cold last. Looking into longer range model guidance it might not be until late November or even early December before we get some more consistent cold to stick around. Put another way, it is going to be a while before we start seeing lake ice or a snowpack. Which was expected for a strong El Nino year.

AVIATION /06Z TAFS THROUGH 12Z SUNDAY/
Issued at 1111 PM CST Fri Nov 6 2026

Satellite shows some mid to upper level clouds moving across the area, beginning SCT but looking to thin out before the main line pushes through after a few hours bringing about a return to SCT/BKN. There is some uncertainty in just how widespread fog ends up getting this morning, with the CAMs showing enough of a low level dry layer piggybacking off of what has been a more consistent global model forecast. For right now, kept the BR in the TAF for AXN/STC/MKT, and included a mention for EAU given the 30 minutes of sub 2sm BR before 05z. Winds will maintain a 210-240 direction at or below 10kts throughout. VFR is expected for all sites aside from the BR chance this morning.

KMSP...No additional concerns.

/OUTLOOK FOR KMSP/ SUN...VFR. Wind NW 5-10kts.
MON...VFR. Wind S to W 5-10kts.
TUE...VFR. Wind NW 5kts.
