KEY MESSAGES
- Periods of light to moderate rain are expected through the remainder of the day and into the weekend. Probability of 0.5 inch of rain is at 60 percent across much of the area, with higher amounts possible in west-central Minnesota.
UPDATE Issued at 1013 PM CDT Fri Apr 26 2024
The mid/upper level low continues it's slow progression east- northeast and is filling in again where a mid level dry slot was in place earlier. The main deformation is still just to our west-northwest. As with before, where returns are less there are still reports of drizzle (sometimes a heavier drizzle) with light fog. There were some adjustments made to reflect higher coverage of light precipitation even in these gaps.
UPDATE Issued at 639 PM CDT Fri Apr 26 2024
The mid level low is centered near Southeast SD and our region continues to see periods of showers and a more organized deformation band/area of rain near our west. This deformation zone is barely over the Devils Lake Basin but should transition east based on HRRR, eventually moving over all of eastern ND/northwest MN tonight. Even between more organized pockets of light to moderate rain, where a mid level dry slot has developed, saturated BL conditions have supported drizzle and light fog. So, ultimately we aren't going to see a break/dry conditions tonight even where radar returns are much less. Near term adjustments were made to temps/winds, but main forecast trends are on track tonight.
DISCUSSION
Issued at 315 PM CDT Fri Apr 26 2024
An active period of weather is expected to continue through the weekend and into early next week. Light to moderate rain is lifting north this afternoon, with the first wave now approaching the International Border. Another wave of precipitation is situated south of the I-94 corridor and will gradually lift north through the afternoon and evening. Rain chances will diminish Saturday morning before our next system approaches late Saturday into Sunday.
An H5 upper low brings additional rain chances Sunday into Monday, with another chance to see isolated embedded thunderstorms. This system will bring similar QPF to the area, with a range of 0.25 inch to 0.50 inch of rain possible from northwest to southeast. East to northeast winds of 15 to 25 mph are possible through much of the day Sunday. Temperatures will be slightly cooler heading into Sunday as highs struggle to climb out of the 40s.
Temperatures on Monday remain on the cooler side, with highs once more in the 40s to near 50 degrees as near-zonal H5 flow prevails. A shortwave traverses the Northern Plains Tuesday into Wednesday, with another chance for light rain.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1151 PM CDT Fri Apr 26 2024
Areas of rain, drizzle, and light fog continue to move across eastern ND and northwest MN and ceilings/visibility remain highly variable (mainly within IFR/MVFR ranges). The low pressure responsible for the rain and aviation impacts will slowly transition out of the region to the east-northeast through midday Saturday and VFR should arrive for northeast ND and parts of northwest MN by the evening. However as surface high pressure passes to the north and a stalled frontal zone may linger in the south, MVFR ceilings are now shown to prevail at KFAR and KBJI. Winds shifting to the northeast should eventually become northerly Saturday increasing during the day as the surface low moves through the region.
