.DISCUSSION...

Issued at 120 PM CDT Sat Apr 5 2025



A weak clipper drops southeastward into the Borderlands later

this afternoon to quickly create a period of light snow showers

lasting into the late overnight hours. Around or less than one

inch of snowfall is expected in the Borderlands to Arrowhead.

There is a 20% chance of up to 2 inches of snowfall north and 

east of Ely from a localized, but isolated heavy snow shower 

chance.

 

Another day of below normal temperatures is forecast Sunday 

north of US Hwy 2, while near to slightly above normal

temperatures set up south of the Highway. A secondary weak 

clipper and trailing cold front again drops southward through 

the Arrowhead and into the South Shore Sunday night into Monday 

morning. This will be the second of two chances of light 

snowfall in this forecast period. Lake effect along the South 

Shore is forecast to bring anywhere from half- inch to a few 

inches of fresh snowfall (40-70% chance) by Monday morning, with

less than in inch in the Arrowhead. Monday will see temperatures

well-below normal areawide as the coldest air behind the front

lingers overhead.



High amplitude ridging enters the region Tuesday to create a 

pattern change that stops the light clipper chances from the 

north and creates a more southerly flow pattern into mid-next 

week. Underneath the ridge Tuesday, critically low relative 

humidity is forecast from 20-25%, although winds are expected 

to remain less than 10 mph though so fire weather conditions 

remain in check at this point. The more notable ridge pattern 

supports above normal temperatures being in the forecast from 

Wednesday onward, along with light rain chances of 20-30% 

chance as ensemble guidance points towards a weak low pressure 

moving through the Lower Midwest in this time period. The 

Northland being on the far northern edge of that potential weak 

low pressure keeps a tight gradient of rain chances from the 

Twin Ports into northwest Wisconsin.



Even further warming and dry conditions into next weekend with 

high temperatures reaching the 50s to 60s areawide.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...

Issued at 1208 AM CDT Sun Apr 6 2025



VFR through the period though a cold front may start to affect

KINL and KHYR 00Z Tuesday onward with -SN. Light westerly winds

become more northerly on Sunday and become gusty in the

afternoon.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...

Issued at 1240 PM CDT Sat Apr 5 2025



Westerly winds under 20 knots this afternoon quickly increase

for a few hour period from the northwest and may (40-60% chance)

gust to 25 knots. The duration and areal coverage was limited

enough though for those 25 knot gusts to keep without any

headline at this time for tonight. Another wind shift to

northerly and a quick increase in speed from a passing cold

front is very likely Sunday night and will likely need a period

of Small Craft Advisories for most zones lasting into Monday

morning.
