First 7 days of this April...April 1-7, 2018...is the 6th coldest on record for Chicago (since 1873): 

1) 27.1˚ in 1881

2) 29.7˚ in 1936

3) 30.7˚ in 1899 and 1975

5) 30.9˚ in 1926

6) 31.9˚ in 2018

At ORD, it's the second coldest on record (since 1959):

1) 30.7˚ in 1975

2) 31.9˚ in 2018

3) 34.9˚ in 1979

4) 35.3˚ in 2002

5) 35.4˚ in 1982

 

*and there's no doubt that Hoosier will get all excited seeing 1936 on the first list. His favorite summer analog year, going back for years and years. :D

Wow Bo...that is some shocking cold for the time of year. What are your normals...around 45/30? If so, this morning’s departures were -30 to -40...which is very difficult to pull off even in DJFM when the daily standard deviations are higher. In April, these departures are nearly unheard of.   

Other low temps in the upper Midwest include -3 at INL, -4 at Hibbing, -4 at Rhinelander (which broke the daily record of 2, set in 1972).

The Euro continues to look pretty nice for later this week.  We may make a run at 70 as early as Wednesday here.  Looks like widespread 70s for a good chunk of the sub Thursday and Friday.  Maybe even some 80 degree potential Friday for many of us.  Between that and the rains later in the week/weekend we should see an explosion of green by this time next week. :sizzle:

Looks to be a short lived period of warmth, before we head back to a similar (but maybe slightly “warmer”?) pattern as we’ve been seeing.

I've been trying to ignore that Joe! lol Hopefully future runs won't depict such a sharp trough.

Going with a blend of 1934, 1936, 1988, and 2012 this year.  :lol:

The sun angle is the ONLY hint of spring there's been up here this year!

Normals for MQT are 44/24, so I assume mine are close to that, as I'm only around 15 miles nw of the office, although 170' higher in elevation and up here elevation next to the lake is everything, which is why I average about 40" more a year than the office.

Another cool but beautiful day with a high of 31.  It hasn't been above freezing here since March 29th.  That streak should end tomorrow with a high of 34, then even a few degrees warmer after that.  Models sure showing a big-dog snow next weekend for the UP (?)...Some pics while I was out snowshoeing today...winter still looks fresh mostly, but I need spring.

At Detroit it's the 13th coldest since 1872 but the 6th coldest in the last 103 years and coldest since 1982. Though there is no snow on the ground (though I did make a small weenie pile with our brief Fri snowfall) the landscape is very dormant. I suspect everything will be late this year.

Michigan unofficially set a state record for April today with -24° at Stambaugh. If this stands it will break the 1982/2003 record by 7°

Wow...I echo Hoosier's comments. Not much more to say. If this holds up, it would be the most shocking temperature record I've ever seen. Departure from normal would be about -50.

Per the COOP report, their high/low for 4/8/18 was 29/-24, with 11" of snow on the ground. Would be great to see the skew-T at the time of the min temp...and the inversion in place.

There are still places in the UP with mid-winter snow depths.  I looked through the COOP reports, and the highest depth I found was Painesdale, at 36".

I hope it shifts south about 1 or 200 miles or I will be ice skating to work. Still a few days out though.

And here we go...the 12z Euro hammers N MN, N WI, and the UP over the next 10 days.  1-1.5" of frozen QPF...with a few spots even higher.  Crazy.

The streak continues for INL and DLH...which are both at 165 consecutive days with at least a Trace of snow cover.  Current depths are 11" and 8", respectively.  If they can maintain this for 18 more days, it will be a full 6 months.  That looks unlikely, even if the below-normal temp regime continues...simply because even a modest mild spell and/or a few sunny days can wipe out the snowpack quickly this time of year.

Curious nugget in the DVN afd

With the exception of the CMC global, the WRF, GFS, and ECMWF push
the cold front through McCook, Nebraska Wednesday night. Local
studies show that when the front goes through McCook, the cold front
will pass through the entire area before a stall occurs. Thus the
currently forecast high temperatures of 65 to 70 on Thursday are in
question. Temperatures could easily be 10-15 degrees colder.

tidbit from mqt... they seem annoyed towards the end.

For the weekend, models continue to show a deep upper low moving
from the central CONUS to to the northeastern CONUS Fri into early
next week. The slow movement of the system would put our area under
the influence of widespread precipitation Fri into early next week,
with potential for 2-3 rounds of impactful snowfall and strong NE
winds/high waves. Of course, there is still significant uncertainty
and it`s too early to get into many details, which is unfortunately
unknown to the engineers on the social media hype train. Many social
media posts are already hyping snowfall amounts of 15-30 inches, but
fail to emphasize the uncertainty in amounts and initial precip type
or that snowfall will be in 2-3 rounds over 3 days instead of all at
once. Will definitely need to keep a close eye on the system as
models sort things out over the coming days.

Just an incredible snowband in Oakland county this evening. Very isolated spots got 4-6", what a shock.

 

We had flurries and snow showers all day, but some heavy squalls between 5-6pm tonight were the real deal, cutting visibility way down & dropping 0.1" of snow imby (61.6" season) and 0.3" at DTW (60.0" season).
