It appears that from a Northeastern perspective the further west you were the colder the anomalies were.

Looks like supposedly continental (ain't that a hoot) Washington DC will be spending the next 7 out of 9 afternoons above freezing during this so-called brutal pattern...of course it's continental y'know .

Out west we experience our coldest time of year in December and January, and then by February things have really started to warm up. It's not uncommon to see flowers and cherry blossoms come out in mid February at 49N in BC, but over the past few years we've seen very cold springs (March and April). The coldest day of the winter was recorded in April a couple years back in Victoria. This is very unusual since we don't typically get the seasonal lag that you find find further east on the continent.
That is an odd pattern, and way down south in California it looks like their rainy season will reach its peak this month, which is later than usual. Of course, there has been a record drought for the previous 3 months so it's not hard to reach the peak right now, but it does fit in with the increasing lag you mentioned. This may be a long-term shift in West Coast climate or it may be a short-term shift combined with a bit of luck . Only time will tell.
We start in the Northeast, where you typically wait until April for the first 80s and June for the first 90s. However, as recently as 2010, 90-degree weather reached Boston and New York City during the first week of April, the earliest on record.
You'll notice that in the past 10 years, the first 80s have reached the Big Apple like clockwork in a narrow window between April 7 and April 25.

As you'd expect, in a typical year the heat starts a little earlier in the Mid-Atlantic, with the first day of 90-degree heat typically coming in late May instead of early June, though there is quite a bit of variability from one year to the next. The nation's capital reached 90 unusually early last year.

The influence of the Great Lakes often keeps cities like Chicago and Detroit from heating up too rapidly in the spring months. Detroit has never hit 90 degrees before the first week of May, and in 2013 the 90s didn't come until a five-day heat wave arrived in mid-July.
However, given the right wind direction (southerly or southwesterly), that lake influence can be held at bay, and 80s can arrive as early as early March. If the last 10 years are any indication, Chicago and Detroit can count on an 80-degree day no later than April 30.

So Houston and Dallas have recorded 80 on January 1, but of course they can't mention any Florida cities in that article.
90F stats would be particularly interesting. Ft. Myers is the outright winner of the earliest category as the only city in the state to have hit 90 in January.
Latest GFS says 40s(F°) still not in sight for many areas and stays mostly below freezing until the 18th now. I am not seeing the warmup and the cold keeps getting extended. Obviously anything past the 10th can change and flip.
Give me 3 letter code and I'll check your area.
Here's Albany. Same even down to Danbury, CT. No 40s and mostly below freezing to the 18th
Panoramic view of temps. Amazing gradient in Texas near Dallas. 30s & 60s not far apart.
Look at the departures!! 20 below normal in one spot, 20 above normal not too far.
