It’s been a weekend full of vicious drizzle in Duluth and Superior which hasn’t really amounted to much in terms of total rainfall, it’s just been more of an annoying type of rain then anything else, but don’t worry, nicer weather is returning for those that miss some sunshine and warmer temperatures.
As for the fog which has been impacting the Twin Ports since Saturday afternoon, well expect that fog to linger into tonight and probably into Monday morning before we see the fog diminish by Monday afternoon the way it looks now.
Here’s some weather lore for ya! “For every fog in August, there will be a snowfall”. It’s coming…
Significant amounts of rain did fall this weekend south of the Northland, with a few different swaths of 1 to 3 inch plus amounts. This rain formed near a warm frontal boundary which remained well south of the Northland, hence the reason why there was very little rain in most of our area this weekend, that boundary was just too far south of our area.
Precipitation totals over the last 60 days have ranged from 6 to nearly 12 inches in much of central Wisconsin into far southeast Minnesota, to only 1 to 3 inches across northern Minnesota and far northwest Wisconsin, with totals of around 5 inches in eastern Minnesota and in other parts of northwest Wisconsin.
Last 60 days percent of normal precipitation — Dry to very dry in the red colors (25-50% of normal) to pretty wet in the green and purple colors (110-175% of normal)
Looks like we could be adding several more 80 degree days to this summer’s total in Duluth over the next 10 days.
Note: 36 days so far this summer with a high of 80 or warmer in Duluth. Normal for a summer is 23 days at or above 80.
Normal high in Duluth from August 9-18 is in the mid 70s, normal low is in the mid 50s.
Scattered showers and isolated thunderstorms are likely tonight over parts of northwest Wisconsin and far eastern Minnesota due to a disturbance and warm front over the upper Midwest, and then we could see some showers and thunderstorms impact northern areas of Minnesota sometime Monday afternoon or Monday night due to a stronger wave and cold front approaching from the Northern Plains, but the timing of that system doesn’t look very favorable to bring widespread rain and severe weather to northeast Minnesota and northwest Wisconsin since the cold front looks to come through the area Tuesday morning/early Tuesday afternoon when there won’t be a whole lot of instability around, but should this front slow down a bit, then we could see a better chance for a few severe storms Tuesday afternoon especially across northwest Wisconsin as there would be higher instability that has built up by then. Note: Wind fields with the system on Tuesday do look impressive, with strong winds from the low levels to upper levels of the atmosphere along with strong wind shear, so certainly need to keep an eye on the timing of the cold front on Tuesday, a later passage could increase the odds for some severe weather impacting parts of the Northland. Stay tuned.
Overall not looking at any widespread rains in the Northland through midweek, with one area of rain N-NW of Duluth, and another area SE of Duluth.
High temperature forecast valid for Monday, August 9, 2021 through Wednesday, August 11, 2021.
Looks pretty warm the next few days, and it will also be humid Monday, with less humid conditions returning Tuesday and Wednesday.
One piece of good news in the weather department today, and that would be the potential for above normal rainfall this week in an area where numerous wildfires continue to burn (red outlined area on map) So will see how this plays out as we may see less and less smoke impact the Northland if a significant amount of rain ends up falling over the fires burning in parts of Manitoba and Ontario this week.
So although we may not see a whole lot of smoke impact the Northland from the fires off to our north, there will be a chance for wildfire smoke impacting the area Monday and Tuesday due to the fires burning over the western US.
18z HRRR model smoke forecast valid from 7 AM Monday to 1 PM Tuesday.
Higher levels of smoke aloft show up in the orange and red colors on the animation below.
