Winter Storm Warnings and Flood Watches blanket the region, rain yesterday with more coming today. This graphic (to the right) is from NWS Duluth and shows the warnings, watches, and advisories that each county in the region is under.
Areas of heavy snow will occur across northern Minnesota this afternoon, evening, and overnight. Rain will be heavy at times across northern Wisconsin, turning to snow overnight, with snow accumulations between 2 and 3 inches by Saturday.
Regardless, most areas will see rain and then snow, continuing the grey and wet trend from yesterday. So far, rivers and streams are showing a rise from runoff, but are staying below levels that may cause trouble.
A few storms yesterday morning before the rain began.I took this radar screen capture (to the left) at 8:37 yesterday morning. Steady rain was moving north across central Minnesota and Wisconsin, but small storms fired ahead of the rain. Unfortunately, I didn't hear any thunder from these micro-cells, but radar did indicate some brief small hail.
A small storm trekked north, just west of my house. This radar screen capture (to the right) was taken at 9:28 yesterday morning. This little cell had been moving north over Bayfield county for 30 minutes before it achieved a position just a few miles west of me.
A friend experienced this cell, very near the time of this screenshot. He reported no thunder, only some brief heavy rain and then sleet. That explains the impressive presentation on radar (max of 53dBz !) but no thunder - internal frozen precipitation was producing a higher reflectivity on radar.
Not a nice day to be outside. This graphic (to the left) is today's Weather Story from NWS Duluth, showing highlights from the forecast through tomorrow.
Areas where heavy snow is possible are highlighted in blue. Rain elsewhere that will transition to snow overnight as temperatures drop below freezing.
The forecast high temperature for my location today is 55 degrees with rain and thunderstorms. Currently it's a chilly and damp 41 degrees while the rain continues to approach from the south.
Average high temperatures should be around 54 degrees and low temperatures around 32. In actuality, today's temps are average, but will dip below average the next few days.
This was the view (to the right) from my kitchen window yesterday morning.
In the section of the yard that I measure snow depth I was unable to obtain a measurement. However, in a few areas of the yard where the snow had drifted and the trees provide shade, I still have a little snow remaining.
This morning, the snow patch pictured, has melted to only a few scattered square feet of white. Today's rain will erase the rest.
The punchline is that tonight's snow may turn everything white again!!
So, what was the exact date you no longer measured a snow depth?! Curious to how the bet will pan out with another dose of accumulating snowfall in your forecast. I may still have a chance. :)
ReplyDeleteThere is some HEAVY rain headed my way as I type.
Yesterday evening was the first time measuring snow depth became impossible.
ReplyDeleteSo, I guess that technically, yesterday initiates our end-of-winter definition.
Your date in our bet was tomorrow, right? The days Scout and I picked were too early, and you were two days too late.
If the forecast turns out, your pick may be closer to the last time snow falls here. At least I hope it'll be the last.
Yep, the 26th. If you are able to measure one inch or greater of snow depth tomorrow or Sunday, then indeed the "Spring-o-meter" would be "reset". Damn, your Winter lasts a long time! :)
ReplyDeleteDo you have your temp/precip data in a spreadsheet you could easily send me?! I'd love to analyze it...
I'll get you a file of my weather data before the weekend is over. I'd need to do some copying & pasting to condense it all.
ReplyDeleteWinter this year is much later than last year. But I don't feel like this is abnormal. A telling sign will be when the last frost occurs, normally about May 15th here. If this crap continues, our growing season may get off to a delayed start.
Wednesday felt like Summer, yesterday and today are a bit more like Spring, tomorrow might be back to Winter. Am I stuck in a warp where time is progressing backwards?!?!
Perhaps you are! The radar looks impressive in ND, SD, and MN as far as the snow goes.
ReplyDeleteI don't want to put "work" onto your plate. If it's too much, don't bother. You do a great job explaining your data w/o me having it in front of my own eyes. But... if you do make the time... *high-five*
I agree with you... this year didn't seem abnormally long for me either.
Looks like Scout's t-storms are making there way across WI.
It's not "work", you just hit me where I've been slacking. Nice aim :) I've been letting the weather station take care of all the temps, but measuring precipitation manually - I don't trust the raingauge on my station, it tends to underestimate.
ReplyDeleteInteresting to see the first tornado watch of the year issued in Wisconsin. Makes me anxious to see if/when such weather will be felt up here. Hopefully this year will be active up here, some aren't.
I'm actually watching the possibly tornadic storms around Davenport, I have family there that isn't always aware of what's going on in the weather.
Sweet radar image!where did you get it or buy it?
ReplyDeleteThanks Scout!
ReplyDeleteSeveral months ago I explored a program called GRlevel3. I liked it enough to purchase it after a 20 day free trial.
If you have heard about WeatherTap, the radar data is similar, but how you move through the radar data is different.
GRlevel3 costs $80, a one-time cost, whereas some websites offer a monthly (or yearly) subscription fee. WeatherTap charges $80/year to subscribe. When you purchase GRlevel3 you even get any updates for free.
I like the flexibility and add-ons in GRlevel3. With a mouse's wheel you can zoom in and out quickly. Clicking on the name of a radar site will instantly bring up that site's radar images.
Up to 26 products are available: Base Reflectivity on 4 levels, Composite Reflectivity, Long Range Base Reflectivity, Rainfall Estimates in 1 and 3 hours, Rainfall Total, Storm Relative Velocity on 4 levels, and Base Velocity on 4 levels. In addition, severe t-storm warnings and tornado warnings are automatically displayed on the radar, as well as radar-derived data such as estimated hail size, MESO, and TVS signatures.
Best of all it's all automatic. It downloads the newest data directly from the NWS when the newest data is available. It's a small program that doesn't use much RAM and only accesses the internet for a few seconds every few minutes.
And there are plenty of things to add on to it: background, road maps, severe t-storm and tornado watch boxes, SPC mesoscale discussion outlines, HPC QPF outlines, different radar color schemes, you can even add a satellite image behind the radar!
You can pay for fancy add-ons, but all the ones I just listed are free. There are also two great support websites, one supported by GRLevel3 users and another hosted by the creator of GRlevel3.
If you want to take GRlevel3 for a free spin, you can go to it's homepage: http://www.grlevelx.com/grlevel3/
and download the setup file and the update file. Install the setup file first, and then updater before opening the program. And then explore what it can do.
There are not many instructions with the program. If you need any assistance, feel free to ask!
Oh, also, the program makes it very easy to save radar images, like the ones I post to my blog.
