Updated for the 10 AM CDT Marine Discussion below.
SHORT TERM. (Today through Sunday) Issued at 402 AM CDT Sat Apr 4 2020
A cold front and associated wintry precipitation have cleared the region as high pressure builds in from the west. Skies will become mostly sunny today as highs warm into the 40s with a few upper 30s near Lake Superior. The ridge axis will move overhead tonight, but more in the way of cloud cover is expected across northern Minnesota as a warm front moves into the Red River Valley. Lows will drop into the teens to middle 20s with the potential for cooler readings in the Arrowhead and Iron County Wisconsin areas where skies will remain mainly clear and winds die off making for better radiational cooling conditions. Have leaned towards the coldest guidance in these areas already, but some spots may still trend colder. A warm front will skirt along the International Border on Sunday and the GFS tries to bring a few light showers to the Borderland. However, with substantial dry air in place, not expecting any of this to reach the ground should it develop and have kept a dry forecast in place. Skies will be partly to mostly sunny into the afternoon hours before more clouds start pushing in from the west as another warm front begins to set up. Highs Sunday will top out in the 50s for most with 40s near Lake Superior.
LONG TERM. (Sunday night through Friday) Issued at 402 AM CDT Sat Apr 4 2020
The upper level flow over the Northland will start out with low amplitude ridging but that will change mid week as a stronger trough moves into the region. After this trough passes late week, north-northwest flow will develop.
Chances for precipitation will return Sunday night as low level warm advection strengthens and a jet streak moves through. Mainly light rain will be possible over the southern half of the Northland with a light wintry mix possible north. Temperatures will warm Monday morning switching any mixed precipitation to light rain and precipitation coverage should wane in the afternoon for a time. Monday will be mild with highs from the upper forties to middle fifties, but off lake winds will keep lakeside areas cooler.
Another surge of warmer temperatures will occur Monday night along with shortwave energy arriving and a developing low level trough. These features will then move through the region on Tuesday. Rain chances will increase overnight and instability will develop leading to a chance for a few thunderstorms later Monday night and into Tuesday over portions of the Northland. Highs Tuesday will be in the upper fifties to lower sixties south with lower to mid fifties further north. Lakeside areas will again be cooler as off lake winds continue. Rainfall amounts Monday night into Tuesday are expected to be from a third of an inch to three quarters of an inch. Some locally higher amounts will be possible with any thunderstorms. Rivers will remain elevated through the week with the rain chances and continued snowmelt.
A cold front will move through the region Tuesday night, pushed along by the stronger upper level trough. A chance for light rain will occur Wednesday. We continue low POPs for light rain/snow late week as cooler cyclonic upper level flow continues. Highs mid to late week will generally be in the forties for most areas.
AVIATION. (For the 12Z TAFS through 12Z Sunday morning) Issued at 645 AM CDT Sat Apr 4 2020
High pressure will move through the Northland today into tonight and aid in scouring out the lingering MVFR ceilings over northern Wisconsin and the Arrowhead. Once these clouds move off, VFR conditions will prevail for the Northland through the rest of the period. Winds will be west/northwest today and become light and variable late this afternoon into the overnight hours.
MARINE. Issued at 951 AM CDT Sat Apr 4 2020
Winds are expected to remain fairly light today as high pressure builds across Lake Superior today from the west. Winds will remain between 5 to 15 knots through the afternoon hours, turning from northwest this morning to southwesterly this afternoon. Winds turn more east to southeasterly on Sunday, generally between 5 to 10 knots. An approaching area of low pressure will be the cause for the easterly winds and they will continue into early next week and may increase to 15 to 20 knots with higher gusts Monday and Tuesday, especially over the far southwest arm of the lake. Conditions may become hazardous for small craft Monday into Tuesday. A cold front will pass through the region Tuesday night causing winds to become west/northwest with a period of strong winds expected Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
