48F low here in Monmouth with another day in the low 60s. 62F right now. I'm enjoying this cool week, as I know we'll have more than enough heat and humidity the next 3 months.

+1

After that little stretch of heat and humidity at the end of May, this cool weather is nice. Dropped down to 45 F this morning. Yesterday briefly reached 62 F for the high, but it was down to 57 F by 5PM.

Any data from the 19th century?

A comparison of the 1876-1899 vs. 1980-2012:

Lowest: 47° June 7, 1879 and June 9, 1980

% of June days with readings < 50°: 1876-1899: 1.4%; 1980-2012: 0.6%

Occasions with minimum temperatures < 50°: 1876-1899: 1876, 1878, 1879, 1880, 1881 (2), 1884, 1894 (2), 1897 vs. 1980-2012: 1980 (2), 1984, 1986, 1997, 2000.

Just another example of how the climate has changed. It is also interesting since 2000 not one minimum reading of less than 50!

You are really annoying with all this "the positive Temprature departures are now the new norm" bulls**t, we get the point that your trying to make, it is starting to sound very redundant.

I think when we total up the period this autumn--> autumn 2013, we'll find that the majority of months were below normal temp wise (for the US as a whole). The past 2 years has been anomalously warm for 1980-2010 standards; we can't continue this way forever. We'll see how that prediction turns out. I'm fairly confident we'll reverse this torch stretch across the US, and see many below normal months starting this autumn (due in large part to El Nino).

Thanks. It makes you wonder how low temps. actually got during the little ice age, and whether or not they even dropped below 40F, i.e. June of 1816?

The June 1816 Snows of the ‘Year without Summer’

Most famous of all cold and snowy late season events would have to be the infamous 1816 ‘Year without Summer’ and the snowfall in June that occurred in the eastern U.S. and Canada. On June 6th accumulating snow was observed as far south as the Catskills in New York (where one inch was reported) and highlands of central and northwest Pennsylvania. Snowflakes were seen at sea level as far south as ten miles north of tidewater on the Hudson River just north of New York City. The deepest accumulations were reported in the mountains of Vermont where drifts of 12-18” were measured. Quebec City in Canada reported 12” on level with drifts up to two feet deep.

The even Greater Snow of June 1842

It should be noted that June snowfall in the Northeast is not a unique event to 1816. On June 11, 1842 widespread snow fell over northern New York and New England and snowflakes were observed in Cleveland, Ohio; Boston, Massachusetts; and even Harrisburg, Pennsylvania (a low elevation site). Accumulations of 10-12” were common in Vermont, so this event was actually more extreme than the more famous snow of June 1816.

Feels like fall (or spring) right now. 57F with drizzle. Good news - A/C has been off this week. Can't say that too much after Memorial Day.

Does this cool prove ominous for a cooler/wetter (2004, 2009, 2003) summer or will it follow prior cool patterns in overall warm - hot summers (2010, 1980, 1988).... The heat that is likely next week makes me think that this cool period may not be any strong indication for the summer either way.

Awesome. What we need is another Mauder Minimum.

Better yet, the right combination of Milankovitch orbital configurations, but that would be totally unrealistic.
