Dec 11-13 MW/Lakes/OV Snow Event? Part V

[Chicago Storm]

Take 5.

[snowstormcanuck]

Not to be the Roman numeral cops, but shouldn't that be Part "V".

[michsnowfreak]

DTX issued a warning for 6-9" for all of the CWA except the southeasternmost 4 counties (DTW-ARB south), where they issued an advisory for 5-8". Seems weird, they shouldve just went warning for all, but oh well. We shall see what happens

[JoMo]

It's V

Also sunny and cold here. 5 days ago I was Jackpot on the GFS

I secretly hate u all

In their disco, they said the fact that southern 4 counties will be rain longer/plus missing the best pivot point snows to the north accounts for the lower amounts. Although I guess 5-8" constitutes warning criteria anyway, at least if it's during one period.

Anxiously awaiting what LOT/IWX has to say..

[Icey]

Huge snow flakes coming down now I'm about 15 miles north of Madison.

[Chicago Storm]

[A-L-E-K]

Cold air wrapping in from the southwest about to put the kibosh on the warm 850s across ne illinois.

Anxiously awaiting what LOT/IWX has to say..

at least IWX went with a warning

MAIN IMPACT...TOTAL ACCUMULATIONS OF 10 TO 14 INCHES OF SNOW...

WITH LOCALLY HIGHER AMOUNTS OF 16 TO 20 INCHES CLOSER TO LAKE

MICHIGAN ARE EXPECTED. STRONG WINDS WILL CAUSE WIDESPREAD

BLOWING AND DRIFTING OF THE SNOW AND SIGNIFICANTLY REDUCE

VISIBILITIES STARTING SUNDAY AFTERNOON.

Maybe it's because it's been a bad stretch for me and I just assume the worse, or maybe because I'm losing interest in this hobby just a bit, but besides Friday, I didn't lose any sleep with this storm. Typically, when the GFS would drop 12-15" on me, like it did last Monday, it would have marked the beginning of 5-6 days of 3 hours of sleep.

None too soon, as it's still trying to mix here at times.

[cyclone77]

Hanging on to pure light rain here. Dry slot 20 miles away. Almost up to 0.40" rain.

pretty much, i'm not even close yet, LOT isn't thinking little to no accums with this action and i tend to agree.

[Moneyman]

Just started to rain here. Looks to rain for quite a long time.

Temp about 35.

Yeah. And the warning/advisory is for the entire storm (tonight thru tomorrow night). And Im the first to admit it doesnt matter what warning/advisory you are under, what matter is how much snow you end up with lol. Its just for the general public, why not just go with a warning to make things simpler, especially if you will throw out totals like that.

DTX for north of DTW: Warning for 6-9"

DTX for south of DTW: Advisory for 5-8"

GRR for Harrys by: Warning for 5-9"

[JoMo]

SGF says 3 hour pressure falls exceeding 6 MB are happening over central IL.

[MidwestChaser]

Wonder if LOT'll do a blizzard warning eventually.

Wow, changeover must be close in Madtown then

[A-L-E-K]

i wouldn't bother unless it looks like the defo band makes any kind of extended stay, the models have been trending it more and more transient, the WSW is enough.

The roads are awful here. Some cities are plowing, some aren't freeway off-ramps are impossible and a lot of people are getting stuck on drifts. My dad said he couldn't get off 494 because every ramp was clogged with cars stuck.

Shakopee now reporting 18" after reporting 13 at 12:30. Chanhassen office reported 11.7" at 12:21 that I either missed or they released late, so that number is up at least a couple inches.
