KEY MESSAGES

- Scattered thunderstorms today into early evening. Risk of small hail and possible funnel clouds.

- Growing signal for strong to severe storms this weekend into early next week.

UPDATE

Issued at 437 AM CDT Wed Jun 24 2026

Surface low and 500 mb was located right near Pembina ND at 09z. These lows will move east-southeast to near Bemidji by 18z and then toward Duluth by 00z. As the low moves east winds at the sfc will turn northwest then north thru E ND/RRV into the 12-22 kt range. Convective temps in the mid to upper 60s along with plenty of moisture in the 950 to 800 mb layer will result in scattering of showers and t-storms across the area today into early evening. With upper low moving thru NW MN could see some scary looking clouds today / funnels. Maybe small hail as well.

Messaging for the weekend into early next week remains the same, but did change late weekend to just weekend as Day 4 (Saturday) SPC 15pct severe did move a tad east into western fcst area. Sunday - Monday period looks like the higher severe risk but this all depends on position of upper ridge to the east and upper low to the west and surface boundaries, jet that will be over the area.

UPDATE Issued at 1155 PM CDT Tue Jun 23 2026

Showers and thunderstorms will continue moving across northwest and west central Minnesota tonight. A few storms could bring small hail to parts of the area; however, widespread strong to severe storms are not expected. Look for lows to fall into the 50s overnight in most areas.

..Weekend into early next week severe potential

The synoptic ingredients typical for producing severe storms in our region will be in place - and conceptually the large scale pattern supports severe storm outbreaks. Details are always the tricky part, especially where individual upper waves track and how far east the greater instability will be. There does remain some uncertainty with exactly how amplified the large scale pattern will be and this will influence those details.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1155 PM CDT Tue Jun 23 2026

Isolated to scattered thunderstorm activity will continue to wind down across northwest Minnesota, with KBJI possibly still seeing a few storms in the vicinity. Ceilings are expected to fall overnight, becoming MVFR to IFR by sunrise. Winds will then pick up by mid morning, with MVFR to VFR conditions expected through early Wednesday afternoon. By mid to late afternoon, however, additional showers and thunderstorms are possible at all TAF sites through much of the late afternoon and early evening before tapering off late Wednesday evening.
