Because Darrow and the NAM are in an intimate relationship. It’s always been that way.

Potential for high wind will need to be watched even in areas that do not see any significant snow. 70kts at 850mb with strong CAA taking place. Assuming that mixes down relatively well, could easily see gusts over 60 and maybe even 70mph. Impressive. I know using 925 is ideal for trying to determine wind gust potential, but that is a paid product.

Add in a potential severe threat in the lower OV with this system as well. Some of these runs, particularly on the euro and the ukie, are looking pretty potent. System looks to have an expansive warm sector with the 00z euro taking the 850mb 10c isotherm all the way to the MI/IN state line. Impressive.

Storm total: 7.4". Light snow continues but is light enough to the point where I think we're done with any additional accumulation. This is at my usual location in Hiawatha.

This is tied with the Jan 31st snow for my favorite event of the season. Think this one will probably take the number 1 spot though. Long duration, heavy rates during daytime and a 6+ event! Can't really ask for much more around here.

A trained spotter in Cedar Rapids just sent in a report with 6.0" and 2" in the last 30 minutes. That's insane! I am in Hiawatha for this storm and while the snow has been pretty heavy, it didn't look to me like it was over 2"/hr. I thought the snow I had in Iowa City a few days ago was heavier than this, though the flakes are probably at least twice as large with this system. 2"/hr vs 4"/hr. Either way, pretty awesome rates out here from this band. It has only really started to lighten up over the past 5 minutes.

Let’s drag on this 500mb pattern we’ve had through May. Please and thank you.

I think this is a pretty good pattern we’re in right now tbh.

Epic enough I've already kinda forgotten getting locally screwed by the last storm. I still picked up 4.5" which is respectable all in all. Looks like a 3-6" event tomorrow night and another probable 3-6" event in the middle of next week.

In Iowa City, I just measured 4.2" and 0.25-0.3" of ice. Family in Hiawatha sent me a picture measuring 8.2". Given precip has mostly stopped, these will be my totals for this storm.

What. A. Disaster. At least 0.25” of ice and probably 4” of snow total. Could’ve been a 6” storm easy if the warm nose did was it was supposed to.

Gonna have to lower my call again, from 5" down to 4". This warm air aloft is firmly entrenched and not moving any time soon. Ice accrual is going to become a problem here very soon. Horrendous performance by all the models.

Rain rain go away, please never come back because this sucks. In other news, mixing line has stalled just north of North Liberty it appears.

I think it'll end up stalling between North Liberty and Swisher.

No, you'll be fine. It's still 90% snow, but there's definitely some drizzle and a few ice pellets mixed in as well.

Mix in Iowa City now. WAA was undermodeled essentially across the board with the worst offenders being the RGEM, GFS and RAP. This will cut into my total, perhaps significantly.

Yea the mixed precip line is coming northward pretty fast. Looking like a mix is probable in Iowa City for a period. Areas just to my north and west should be okay(CR).

Back to 1"/hr rates easy. Flakes are only average sized but there's so many of them it looks like heavy rain almost. Can't see the U of I hospital, about a 1/2 mile away. Vis is definitely under 1/4 mile atm.

I have a feeling this is the one to get us to 6". It's been puking snow here and never really stopped. Flakes are pretty small right now though. Probably 1.75" in IC already. That band of orange that passed over me earlier was really something.

I’d upload the 2 pics I took but amwx is like nah. So theyll have to wait until later.

Snow/Sleet at the onset in IC.

Correlation coefficient also indicating sleet on the leading edge of the heavier precip. The inversion(more like an EML) is very dry and the sleet should switch to snow as the column cools.

Snow is ahead of schedule out here in Iowa. Already past US34 and almost to I80. Still dry in IC.

It's also pretty weak sauce.
