29. A wet period ahead for Wisconsin, at least the next two days.
I wanted to start off this post with a map (to the right), from USWX.com, showing where Flash Flood Watches have gone into effect this morning. The medium green - which covers counties from the Arrowhead of Minnesota all the way south through Wisconsin, southeastern Minnesota, and Iowa - indicates concern for these areas that up to 4" of rain may fall today and tomorrow.
While exact rainfall amounts are uncertain, enough rain is expected to compound already wet ground and high streams to quickly cause more problems.
Flood Statements, scattered across southern Wisconsin in darker green, indicate updates on rivers and streams that are already at/near flood stage. These areas may be upgraded to Flood Warnings if rivers continue to rise.
It may be a little dangerous to try pinpoint exact rainfall amounts, but it is useful to have an idea where the heaviest rain may fall and a rough idea of how much to expect.
This map (to the left), from the HPC, gives us a good idea of the next two days rainfall - from 7:00 Wednesday to 7:00 Friday.
A large chunk of Iowa may see more than 3" of rain, as well as the northern half of Wisconsin, by dawn on Friday.
A closer look at Wisconsin.
I pulled this image (to the right) from my GRLevel3 program, which shows the Quantitative Precipitation Forecast (QPF) for the next 24 hours across northern Wisconsin.
I added some numbers to the colored contour lines, hopefully making it easier to get the general idea of amounts.
Over 3" possible someplace across the northern tier of counties?! The red contour line encompasses a large area of the Northern Highland Region of the state. I have family that lives inside this highlighted area.
The northern half of the state has not seen the heavy rainfall that the south has been plagued with, so 3" of rain would not be as devastating up here as it would be down there, however, 3" is still a lot of rain during one event.
But the rain will slide east tomorrow.
While Iowa, Minnesota, and northern Wisconsin will see the heaviest rain today, the heavy rain will move eastward tomorrow, impacting eastern and southern Wisconsin, the UP of Michigan, and eastern Iowa.
This map (to the left), from the HPC, shows the QPF map for tomorrow.
The UP of Michigan has seen very little precipitation over the last few weeks, and could probably use more rain, while southern Wisconsin will only see more flooding with any amount of new rainfall. Several rivers and streams are cresting today and will likely see a higher crest by the weekend, especially if heavy rain drenches areas that are already underwater.
The weather across the far north.
Yesterday at 2:00, in the early morning, a cold front sagged south into Wisconsin from Canada, which is visible on the chart from my weather station (to the right).
As the cold front moved through, very light winds switch from the NW to the E, which dropped temperatures quickly.
As the temperature fell to dewpoint (this means relative humidity hit 100%) fog resulted. A Dense Fog Advisory was in effect across the counties near Lake Superior yesterday morning.
The same air mass continued yesterday and is still in control this morning across the area, including Maple Hill and the Bayfield Peninsula.
Temps: 43.8 / 51.0 Dewpt: 40 to 45 degrees Winds: < 2 mph from the E. Baro: rising from 29.60 "Hg up to 30.00 ". Sky: morning visibility < 1/4 mile, some sun by sunset.
Today's Numbers (so far):
Temps: 43.8 for an overnight low. Dewpt: 42 to 44 degrees. Baro: up to 30.10 "Hg now falling to 30.05 " Winds: < 2 mph from the E/NE. Sky: thick stratus overcast. The meaning of signs.
Washburn does have a nice walking trail between downtown and the bay, and this photo does give a nice glimpse of the picturesque view.
It's the sign that my eyes then gravitated towards. Yes, a universal image that denotes a walking trail, but I have a sneaking suspicion that it has a second meaning - that shorter people should walk behind taller people.
At first I was a little peeved, being a little shorter than I'd like, but I quickly cooled off when I realized that I do like walking behind taller people... it's nice to have a spiderweb-clearer ahead of me on a trail.
