December 2024 General Discussion

[OrdIowPitMsp]

Arctic Front later today, first temps below zero of the season and potential system fri/sat. 
 

Nice to have a bit of an active stretch.

these one day brutal cold shots interrupting our 40s and 50s are annoying as sh#t.   Like getting a bucket of ice water dumped on you .

Yep, nothing like those 20+ degree swings over a short period of time. Midnight high of 35 and will end up flirting with subzero lows by tomorrow night.

what section of the house do we go to in the event of a snow squall warning? Southwest corner? And do we open windows?

Go outside and film while debris goes flying past you, screaming and swearing ruining the video.

If we'd at least get some decent snow out of the cold shot - unfortunatly, it's usually a high of low 20's with sun.  Give me upper 20's-low 30's with snow

Tracking tomorrow's snow squall will kind of be like tracking a line of severe storms.

The high temperature on Wednesday could actually end up
occurring late morning immediately ahead of the much anticipated
strong arctic cold front expected to reach northwest
Illinois/Rockford area toward midday and quickly push across the
rest of Chicagoland into northwest Indiana through the
afternoon. This front will likely be accompanied by a period of
gusty snow showers and potentially a dangerous snow squall. Hi-
res guidance continues to suggest conditions will be conducive
for snow squalls. The RAP highlights well the potential for a
narrow axis of low-level frontogenesis to develop with the front
coinciding with steep low-level lapse rates along with a modest
3-hr surface pressure rise/fall couplet on either side of the
front. This could aid in enhancing wind gusts within this fgen
band locally up to 40-45 mph.

A lingering question remains when these "ingredients" all come
together, with the snow squall parameter increasing as the front
approaches the I-55/57 corridors into northwest Indiana. While
the Rockford area is not fully out of the woods, it is possible
coverage is lower west of the Chicago metro. If this scenario
plays out, the snow showers/squall may be developing as the
front moves into the Chicago metro. Regardless, all areas of
northern Illinois and northwest Indiana will want to be prepared
for a brief period of sharply reduced visibility in
snow/blowing snow and a quick coating on roadways resulting in
slick travel during the afternoon/evening commute.

To put this round of possible snow showers/squalls into
perspective compared to last week`s, surface temperatures will
already be below freezing (which were too warm last week for a
more robust initial snow squall with the front) and would
support snow readily accumulating on roadways. However, the
pressure gradient is not as strong, with peak wind gusts
currently expected to remain in the 40- 45 mph range versus the
55-60mph wind gusts observed last week. Nevertheless, multiple
hi-res models depict localized visibility reductions as low as
1/4 mile within these snow showers/squalls.

Still waiting for the Frostnado.

DAB+ out there to whiten things up

[OrdIowPitMsp]

Half inch overnight with the arctic front. Snow squalls went through the metro half an hour ago and deposited a few tenths more. Temp at 10 and falling.

[Brian D]

Finally back after computer issues. After some good snows across NE MN Sun into Mon, now the bitter wx arrives today for a couple days. Wind chills -20 to -40 anticipated. Cold wx adv issued. Replaces the Wind Chill advisories. Extreme Cold warning will replace Wind Chill warnings. 

[sbnwx85]

Seeing some snow showers popping up on radar. I think the cell near South Bend has a hook 

[Brian D]

Early data showing a warm Nov similar to 2020. And Fall ends up as 3rd warmest. 5 & 10 yr trend charts shown respectively.

[nvck]

Decent rates here for about 30 or 40 minutes, enough to about half cover the grass. Just flurries now, but hoping for another inch or two tonight, maybe like last Wednesday?

[CIllinoisSnow]

Got a real nice snow squall getting ready to move in, unfortunately sun is out currently and temps are warmer than expected so accums will be held to a minimum, fun either way though

Blizzard Warning issued here:

Quote

ISSUED: 1:35 PM DEC. 11, 2024 – ENVIRONMENT AND CLIMATE CHANGE CANADA

Hazardous lake effect snow squalls expected tonight through Friday. Blizzard conditions likely late overnight and Thursday morning.

Hazards:
Locally heavy snowfall with accumulations of 40 to 80 cm through Friday.
Westerly winds gusting to 80 km/h resulting in near zero visibility in blowing snow.
Peak snowfall rates of 5 to 10 cm per hour.

Timing:
Beginning late today and continuing into Friday, with the worst blizzard conditions late overnight and Thursday morning.

Discussion:
Lake effect snow squalls off Lake Huron are forecast to develop later today or tonight. Strong westerly winds gusting up to 80 km/h will develop late overnight into Thursday morning resulting in widespread blowing snow with near zero visibility. Winds should ease somewhat by Thursday afternoon, although heavy snowfall will continue into Friday. Travel is expected to be difficult to nearly impossible.

Locally higher snowfall amounts greater than 80 cm are possible if a strong snow squall band remains over the same area.

Road closures are likely given the expected poor travel conditions.

I'm surprised. My gut says it won't verify here but along the shoreline more likely. This would be the 5th blizzard warning since I started tracking wx (more common in recent years). I could get 30cm/11.8" in the next 36 hours. There is mod-heavy snow this aft not sticking on roads yet. Snowglobe here again.

Congrats! And thank you for adding inches into your measurements. This lazy American appreciates it

[OrdIowPitMsp]

Sunset a few minutes ago and already down to 4F. Our coldest temp of the season.

[cyclone77]

Picked up 0.3" of snow this morning, up to 0.7" for the season.

MLI did better inside the main swath and picked up 0.9", 1.3" for season.  DVN just 0.4" today.

[Stevo6899]

Never been more grateful to be in Florida the next few days. No snowcover and high temps in the low 20's. gross

[SchaumburgStormer]

Front coming through was a major yawner 

[OrdIowPitMsp]

0.6” at the airport today. 

2.3” season to date.

+1F

[OrdIowPitMsp]

KMSP has fallen below zero for the first time in the 24/25 cold season as of 7pm this evening.

-1F

[nwohweather]

Nice squall right now! My grass is mostly covered, gotta love it

[A-L-E-K]

will be happy once this CAD moves out

[OrdIowPitMsp]

-8F this morning. 

Love it or leave it. 

[SchaumburgStormer]

Bottom at 1F last night. Typical whiplash december with upper 40s in the forecast soon. 

[madwx]

Down to -2F here for the first subzero low of the season

[Brian D]

-10's (nearer the Lake) to -20's (interior NE MN) this morning. She's a bitter one. Highs in the sd's today with another bitter am on tap tomorrow before things warm up again. Winds are calm-5 right now, but the day wind will kick in keeping wind chills on the lower side today. Cold wx adv will stay in effect through tomorrow am. Like the new change. Wind chill's are one thing, but temps get just as cold as wind chills, so new adv is a good reflection of overall conditions, wind or not. 

[Brian D]

I-Falls -24 (T 7th), Hibbing -20 (5th), Duluth -18 (T 4th), Ashland, WI -12 (T 5th), Brainerd -13 (7th), St. Cloud -11 (T 7th), MSP -8 (T 8th), and Eau Claire, WI -9 (T 6th). Significant cold snap. Will see how tomorrow am ranks. 

[michsnowfreak]

Squally with blowing snow overnight then  below zero wind chills this morning. Picked up 1.3" here, 4.0" on the season. DTW had 1.2", so 3.7" on the season. Some areas (detroits immediate NW burns) got 2-3" overnight.
