KEY MESSAGES
- A clipper system will bring mixed precipitation and the potential for up to around 3 inches of snow from Friday afternoon into midday Saturday.
- A storm system will move across the Midwest early next week.
The system continues to trend farther south, with a low chance (10-20%) for winter weather impacts for southern portions of the Northland, primarily in NW WI.
- Gradual warming this weekend through next week.
DISCUSSION
Issued at 402 PM CDT Thu Mar 28 2024
Rest of today:
Sunny skies have developed across most of the Northland as high pressure settles into the region, with the exception being across the tip of the MN Arrowhead where very light snow/flurries had lingered into the early afternoon. Afternoon temperatures are topping out in the upper 20s to mid 30s have been accompanied by westerly winds gusting to 15 to 25 mph, but will quickly weaken and become light this evening.
Tonight:
High-level cloud cover gradually builds into the region tonight ahead of an approaching clipper system to our west. While the night looks quiet for the most part, there is a signal for some patchy fog tonight into early Friday morning from central Minnesota into northwest Wisconsin, and up to around Duluth. The probability for visibilities to be reduced to around a mile remain around 30% or less at this time.
Friday - Saturday:
Cloud cover continues to increase across the region on Friday and Saturday as the clipper moves east across northern ND and northern MN. Precipitation chances begin earliest across central and north-central Friday afternoon and then expand eastwards across the Northland Friday evening into Friday night before exiting the Northland from west to east on Saturday morning into early afternoon. Model thermal profiles continue to support a mix of wintry precipitation with this system in the form of rain, snow, freezing rain, possibly some brief sleet. The potential for freezing rain/sleet would be primarily Friday evening into early Saturday morning when temperatures are below freezing before warming above freezing again by late Saturday morning across the Northland. A loss of cloud ice on the back side of this system Friday night into Saturday morning could also lead to freezing drizzle, as well.
Overall, the snow amounts trended slightly upwards for portions of northern Minnesota and the North Shore where precipitation will primarily be in the form of snow. Amounts range from a dusting across the southern tier of counties in our CWA to around 0.5-1.5 inches around the US Highway 2 corridor to 1 to 3 inches north of US Highway 2. Localized amounts slightly over 3 inches cannot be ruled out along the North Shore due to easterly winds off of Lake Superior into the higher terrain of the North Shore leading to a bump in forecast snowfall due to lake and terrain enhancement. Ice accumulations are primarily confined to the US Highway 2 corridor and areas south where generally a light glaze to a few hundredths of an inch of accretions are possible. The freezing drizzle could lead to some very light glazes of ice into northern Minnesota, however, depending on whether or not loss of ice crystals aloft occurs there Friday night.
Late Sunday - Early Next Week System:
Ensemble guidance is in good agreement on a Colorado Low developing late Sunday, with fairly good agreement in the track of the low cutting eastwards across southern portions of the Midwest from Sunday night through late Monday. The trend of guidance sliding this system farther south of the Northland continues, so while precipitation probabilities of 10-30% get into central MN into NW WI late Sunday through Monday night, precipitation amounts have continued to trend southward. NBM probabilities for greater than 1" of snow with this early week system only look to be around 20% or less for southern portions of the Northland, highest over NW WI. Given forecast temperatures Sunday into early next week, this precipitation would likely be in the form of a rain/snow mix.
Warming Temperatures into Next Week:
We see temperatures gradually turn warmer this weekend into next week, with highs warming from the upper 30s to mid 40s this weekend to widespread 40s by mid next week. There is even some potential for some 50s to creep into the Northland late next week as a ridge builds overhead, but a lingering snowpack may lead to forecast temperatures needing to be lowered a few degrees until the snow melts completely. Some lingering light precipitation is possible into mid-next week.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
Issued at 1213 AM CDT Fri Mar 29 2024
VFR conditions prevail at all terminals through midday as winds become easterly. The chance for fog and low visibilities early this morning has decreased dramatically. An area of snow and rain pushes from west to east in the late afternoon into the evening bringing worsening conditions. At least MVFR expected by the end of the TAF period, with some pockets of IFR possible (and likely just beyond the TAF period). Should be mostly snow for INL, HIB, and DLH. Some rain/snow mixed possible at BRD with a low chance for freezing rain.
At HYR, precipitation type begins as rain, but freezing rain is possible later in the evening.
MARINE
Issued at 402 PM CDT Thu Mar 28 2024
Westerly wind gusts up to 20 to 30 mph continue over western Lake Superior the rest of today before quickly weakening this evening and tonight, though some elevated waves may linger across portions of the South Shore into mid-evening. Small Craft Advisories expire at 7 PM CDT, except for Duluth to the Outer Apostle Islands where 2-5 foot waves will linger the longest.
Low pressure moves east across the region Friday afternoon through Saturday, which will likely lead to strong and gusty northeast winds in the southwestern arm of Lake Superior and the need for additional Small Craft Advisories.
