4-5-19 Minnesota Forecast: Discussing fog potential and scattered shower/storm risks into the weekend…Update on mid-next week system. I.

Today’s Video:

Good morning everyone! As previously discussed, areas of dense fog were able to develop late last night into this morning, resulting in Dense Fog Advisories being issued across the far southern portions of MN. The bulk of these advisories run until 12pm CDT when the fog becomes less prevalent.

Simulated radar through 1am CDT Sunday: Scattered showers will be possible across the central tier of MN stretching from just south of Fargo to Duluth during the afternoon hours. Elsewhere, look for a boundary to setup this evening in southern MN with scattered showers and a few storms developing mainly after 7pm CDT this evening. This activity slowly lifts eastward overnight into Saturday, largely exiting and to the east by 4pm CDT. Watch for additional scattered showers and isolated storms to develop ahead of an approaching storm system after 4pm CDT Saturday in southwestern MN that spreads quickly eastward and bring scattered shower and storm risks overnight to the southern two-thirds of the state. Northern MN will observe more in the way of light rains as Saturday night progresses into Sunday morning. Scattered convection (showers and a couple storms) will remain the theme into Sunday, but finally pushing out of the state mainly by 7pm CDT Sunday. Precipitation will range between 0.25-0.75″ for virtually all areas and places that can observe heavier showers (a few storms) can manage localized 1.0-1.5″ of rain, though this is more likely in southern MN.

The fog risks aren’t finished as Saturday and Sunday morning both feature the potential for fog once again: Northern MN Saturday morning and northwestern MN into Sunday morning. Most of this fog will be able to erode by late morning.

Watch for some upper-level energy clipping far northern MN Monday afternoon into the overnight bring the risk for light shower activity. Since yesterday’s update, a majority of the guidance has trended less amplified with the mid-next week system, keeping a majority of the precipitation at least hugging the MN/IA border into the Central Plains. The European Model (not shown) is still further north and brings a heavier dose of snow to southern MN mid-week. However, current trends suggest this is too far north and will likely adjust south with time. Nothing is set in stone yet as fluctuations in this system’s track and intensity are likely. Something to keep in mind as adjustment will still be possible. Current favored solution into mid-next week:

Total precipitation through the next 7 days: Definitely substantial differences between model guidance for this week’s precipitation. Pending the track of mid-week’s system, the area can stay drier for mid-week (American Model approach) while the European still brings that heavy band of snow. Again, precipitation will be skewed based on this system but as of right now we favor the American Model’s solution (left) with heavier precipitation remaining just south. Most of what is shown at least from the American Model comes through the weekend.
