A FINAL PERSONAL APPEAL
Hi all. I'm still hoping for 420 dollars to reach my fund-raising goal (I'm 97% there). Personally, I'm appealing to those of you who appreciate the reliability, honesty, accuracy, and knowledge of the site, to consider a donation, (especially if it helps with financial decisions related to your business). If you fall into any of these categories and find value in the effort put forth, I humbly ask that you make a $20 dollar investment into this unique and reliable product.
Thanks so much, T. Swails
NOW, THIS IS DOWNRIGHT IMPRESSIVE...
Considering how hostile Wednesday was, Thursday was a spectacular day weatherwise around the Midwest, with a lot less wind and abundant sunshine. What a contrast to what I'm about to show you took place 24 hours earlier, thanks to Judie Tosh who follows my site. She alerted me to some pictures of Wednesday's blizzard posted by Ed Hanson of KCCI TV in Des Moines. Ed is a good old Iowa boy and a fine journalist. Just look at what 65 mph winds and heavy snow can do. Thanks to Ed and these fine Iowans who rode out the blizzard and snapped these amazing pictures.
Most of these drifts were created by just 5–6 inches of snow, wet snow at that. Imagine if there was 10-15 inches more, which there could have been if an inch or rain had not fallen before the transition to snow. What a sight that would have been. Make that, what a "mess" that would have been.
These are some of the snow reports compiled by the NWS and the Iowa Mesonet
Remember I mentioned earlier how Thursday was a bright day with lots of sunshine. That allowed this visible satellite image from GOES 16. Snow is shown clearly on the ground NW of a line from Washington, Iowa to Dubuque. It's cool to see the river valleys etched in the snow.
SPEAKING OF SNOW...
A new weather system has already spread a band of snow through parts of the central Midwest. Low pressure spining across Missouri has laid out a baroclinic boundary over southern Iowa. Moisture over-running it is providing the lift for a narrow swath of snow that's expected to fall mainly north of I-80 to north of HWY 20. Amounts further south will be minimal, thanks to a mixture of rain and snow. Little if any precipitation should occur from HWY 34 south. You can see the snow band over the north on the EURO surface depiction at 9:00am Friday.
Temperatures at the surface will warm to the 34-36 degree range within the snow band by late afternoon. That hopefully keeps roads slushy, limiting travel issues. However, there is likely to be a period in my counties north of I-80 where snow falls heavy enough to accumulate on the roads. Over the far south, where little precipitation falls, highs could reach 45-50. Take a look at the expected range of high temperatures on the EURO.
As far as how much snow falls, guidance is reasonably consistent in showing amounts of 1–2 inches just north of I-80. The heaviest totals are most likely from HWY 30 north, where 2 (to perhaps 3) inches is consistently shown. The snow could be banded somewhere within that region, with a couple spots in east central Iowa getting 3"+. The snow will be ongoing at daybreak, where it tapers off and ends by early afternoon. Some light drizzle is possible at times at the tail end of the event. The NWS has put out a Winter Weather Advisory for 1–3 inches of snow from HWY 30 north until 3:00pm Friday. Slushy roads are likely there.
Here's what models are indicating for snow. These are not hard forecasts, just raw model output that forecasts are based on.

The GFS
The 3k NAM
The NAM
The HRRR
Skies will clear following the storm, and the weekend looks mostly sunny. After a pleasantly cool day Saturday, a significant warming trend sets in on Sunday that should bring us a real taste of spring next week. Here's what the next 2 weeks look like on the EURO meteogram. Only 1 out of 14 days has a high colder than the 51 after Friday. I will take an extra helping of that!
For those dealing with snow in the north today, rest assured it won't be around long. Happy Friday and Roll weather, and if you can spare a donation to get me to my goal, I will see to it that it's money well spent....TS
