March 2017 Discussion & Observations

Only 42F and rain here in the Bronx. Doesn't look like we'll see the 60s forecasted. Forecasts have been too high for three days in a row: it was supposed to be 60F Saturday, only hit 55F, yesterday was 41F instead of 49F, today it's 42F instead of 60F. 

Been a cold March, and departures should stay around -3F given the cold front Wednesday. It's just that averages are warming so cold is 40F and rain now instead of 30F and snow two weeks ago.

Looks like NYC will be down in the 30s Wednesday and Thursday night again. Still need that heating.

might see some late day highs today as the winds turn S and SW.   But agree-60 would be a stretch.  Still 41 here...up 3 degrees from this AM

Only the 5th time since 1880 that NYC reached 70 degrees during the first week of March without making it to 70 for the rest of the month. The previous 4 times were following colder winters.

Year....DJF

2017...39.3

2009...34.2

1974...35.3

1972...35.7

1880...37.5

Why aren't daily average temperatures simply all the hourlies added up then divided by 24.

Of course we have a High and Low for the day but wouldn't a true average be as I postulated above?

Wouldn't it be more representative then an fluke high at midnight skewing the day's average?

You can suggest a method for calculating for your phd.

I honestly haven't looked much into the drought recently but one snowstorm doesn't make up the rainfall deficit up here. 

I'm not talking about making up a deficit, when you make up a long term like we have much of that water runs off because there is no way for it to soak in or be stored.  Currently if you step off the pavement water squishes up around your shoe, creeks are running hard, local ponds are overflowing and the reservoirs are as full as they can be with the overflow res.'s running over their dams.  Everything is soggy and saturated so at this point anything we get here will just run off.  It may be different in sw CT where Brian is but 25 miles north of him any more water would have no good place to go.

Of course it would, but years ago they didn't have the technology for that, now it would be simple. Of course 30 year averages and comparatives would all be thrown upside down.

They had the technology to divide by 24 years ago...

The issue is not one of technology, its that many of the secondary obs sites used high/low in the past because they weren't constantly monitored.  

Of course, there's no reason to divide by 24.  It should be done using integrals now that we have constant obs.
