Lol. You obsessed?

I must say you live your stats.

I think we finally see our pattern change Cam.

Looks like we are finally going to get some rain as well.

I still see October above normal. Second hAlf warm up

Damn! Windows all down after I got up this morning. Now I think it's warmer outside than in, so they're all going back up again.

Clear Skies has New England below normal. Clouds = above normal.

Chicopee, MA just hit Freezing!

From NWS Upton. Looks like Danbury was the winner for the low last night.

With the combination of clear skies and relatively light winds, it was a cold morning in many areas due to radiational cooling. The cold spot in our area was in Danbury, CT, where the low temperature reached 39 degrees this morning!

The name is a misnomer it's actually a reflection of accumulated daily DEVIATIONS from an average temperature of 65 degrees (supposedly considered by scientists to be the ideal for clothed human comfort) and can show some interesting results/comparisons.

For example, using Central Park's stats, 1961 is likely to have more Cooling Degree days for September than 2015 is even though the average temperature of Sept. 2015 likely finishes warmer (1961 had 284, 2015 is at 266 and the next three days while likely to average over 65 are probably not enough to put 2015 over the top). Similarly 1961 had 20 Heating Degree Days, which is just a little under the average of 34 for the month (a handful of Septembers have had less than 10), and 2015 is probably going to have just 1 (unless the Central Park temp suddenly goes up to 73 or higher today, today's average will be 64).

This reflects more extreme high temps in Sept. 1961 than in Sept. 2015 (they had a record 8 90+ degree highs, vs. 6 this time around) and a generally bigger diurnal spread in temperatures (i.e. both higher highs and lower lows in Sept. 1961 than Sept. 2015).

Another example is that despite the super cold February and historically cold combined January to March period, the Heating Degree Day seasonal total for July-June 2014-15 for Central Park was just under 5000. That is actually not much above the average of around 4800, it only a tiny bit over the prior year's number and there are plenty of years before 1950 that had over 5000 Heating Degree Days for the season in NYC (after that it happened about once or twice a decade, even the last time it was over 5000, 2003-04, it was a significantly higher number than last year). This reflects two things:

- The fact that the other months were often well above normal (i.e. December 2014, May 2015).

- The general trend, especially in Central Park for some reason, towards higher nighttime lows the last 2-3 decades. The fact that last February was the only top 10 coldest Feb. to not have a subzero low kind of shows in this data.

Todays model update says cool & wet. Here comes the rains they say. Good soakers and chances multiple days. We'll see.

Would also mean warmer nights then previous (clouds) but still cool days maybe even "raw" feeling. 50s and rain would be Novemberish. We'll see.

Tues/Wednesday and again Thurs/Friday but theres so many differences in timing of things that forecast confidence is low.

All I will say... its been a nice dry period getting things done around the house not worrying about rain. I lifted a tarp off the ground sittng for weeks. It was dry. Gutters dry enough to clean easy. Leaving lawn mowers outside without worrying. Its been nice. Too lazy to split wood one day but not worry cause next day was dry too.
