Area Forecast Discussion National Weather Service Duluth MN 245 PM CDT Mon Jun 2 2025 .KEY MESSAGES... - Rain and thunderstorms late today through Tuesday. An isolated severe storm and localized flooding are possible. - Areas of smoke continue into Tuesday night. Air Quality Alerts are in effect. - Isolated general thunderstorms possible Wednesday, with the next round of more widespread precipitation and storm chances occurring this weekend. && .DISCUSSION... Issued at 245 PM CDT Mon Jun 2 2025 Severe thunderstorms are possible this evening into parts of the greater Brainerd Lakes region as a mid-level shortwave trough rotates through a more broad upper-level deep open wave in the central continental United States. The main hazard will be supportive of damaging wind gusts through mid-evening today in the Brainerd Lakes region. A recently issued Severe Thunderstorm Watch is in effect for Cass, Crow Wing and Aitkin Counties through 7 PM CT today. Further north and eastward, a much decreased CAPE gradient and less-conducive shear profile decreases that severe threat closer to the Interstate 35 corridor and up into the Iron Range. A few strong thunderstorms for those areas though cannot be ruled out to produce wind gusts to 50 mph still this evening. A few rounds of heavy rainfall this evening could also create conditions for a quick inch or two of heavier rainfall. The forecast maximum rainfall amounts if those rounds of heavier rainfall line up over the same location would be three inches on the upper-end. High-res guidance has been generally trending to bring this upper-end maxima potential to the greater southern Itasca through western St. Louis County region. After this evening convection dies out and the front stall into northwest Wisconsin, a surge in moisture builds into north-central Wisconsin and inland northwest Wisconsin overnight. Reinforcing mesoscale forcing lifts northeastward Tuesday morning to create a period of more widespread heavier rainfall in a line from Sawyer to Price to Iron Counties. These counties have a high chance (60-70% chance) of seeing at least one inch of rainfall by the Wednesday afternoon time period. A secondary weak trough passing through the Northern Plains Wednesday accompanied by a jet streak in the upper-levels, CAPE progged around 600-800 Joules and a weak impulse of pacific moisture keeps general thunderstorm chances in the forecast for north-central Minnesota. Will have to keep an eye on the chance of limited coverage, but strong thunderstorm potential for the Western Iron Range and northward to the Rainy River basin area. Near normal temperatures end this week ahead of the next more widespread round of precipitation and storm chances build back in later Saturday and last into Sunday as a trough moves through the US/Canada Plains border region. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1235 PM CDT Mon Jun 2 2025 Southwest winds prevail over much of the region this afternoon except along and north of the Iron Range. An incoming frontal passage this evening will bring a wind shift to northwesterly for all terminals by 12Z Tuesday. An area of strong thunderstorms is expected to impact parts of north-central Minnesota later today, which may include the Brainerd Lakes to the western Iron Range. Large hail around an inch in diameter and winds gusting to 55 knots would be the primary hazards from any isolated severe thunderstorm through about 01Z. Other areas may still see gusty winds to 50 knots into northeast Minnesota. Smoke from Canadian wildfires will drop southeastward the rest of this afternoon and may bring MVFR visibility reductions to some terminals. Smoke lingers in the Arrowhead to South Shore region Tuesday where smoke remains in some TAFs. && .MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 220 PM CDT Mon Jun 2 2025 Gusty southwest winds along the shoreline region of the South Shore into the Twin Ports are expected to remain into this evening. A few zones of Small Craft Advisories are in effect until late this evening for this hazard. Winds quickly shift to northwesterly late tonight and are expected to remain below 20 knots into mid-week.
