Sure they do--it's length of day. Night starts two hours earlier.

If that were true, how do you explain the below which was taken on the longest day of the year? I'm sure I could find many BOX examples like this one, but I picked a random day in June and many WFOs this day were issuing their afternoon forecast for tonight as early as 3-3:15 in the afternoon. It just depends on how complex or difficult the forecast is.

Afternoon coffee?

Seriously, dude, don't get your panties in a bunch. IBut, I'm glad you had a June 22nd forecast in your archives. by the way--I said p/c. :)

Panties aren't in a bunch, but when I see something patently false I think it should be corrected even if it's something minor like that.

Frankly, I don't think it's patently false. Of course there are exceptions (so is 2' of snow in October). But face the fact--when night comes two hours earlier (or 4 hours earlier), it's incumbant to provide that forecast earlier. Moreover, the duration of the forecast periods (today/tonight/tomorrow) respectively change in duration so it makes sense that afternoon forecasts stay up longer during the summer.

Anyway, my initial comment was midly funny (in my mind). I think your reaction (the need to correct "something patently false") though is hysterical.

It's coming folks. Op Euro is a PHAIL

*** ALERT *** LATE OCTOBER COMES IN LATE SEPTEMBER !!

Definitely an entertaining read, lol.

He hates those CPC definitions of AO and NAO...I can't say I blame him though...they have changed it several times in the past decade and sometimes it makes no sense. That classic North Atlantic ridge pattern is an example...its not the -NAO loading pattern.

The AFN conspiracy continues....ORH high was 68F and AFN was 71F on a northwest flow well mixed atmosphere where AFN even had 850 temps 1C cooler in this airmass.

Their ASOS has either 1 more of these things going on with it:

1.) The siting environment has changed...(i.e. maybe they poured a huge concrete slab right near the site)

2.) The thermometer itself is erroneous.

3.) The ORH thermometer is running too cold now.

I think I eliminated #3 pretty fast. The 3 closest mesonet sites had highs today of 68.7F (700 feet in Holden, MA), 66.3F (1100 feet in Rutland, MA), and 69.8F (600 feet in Barre, MA)...this makes it extremely unlikely that the 68F high at ORH is in any major error. KORH is at 1000 feet.

However, when one takes a look at the closest 3 mesonet sites to AFN, a different picture emerges. The highs of the 3 closest mesonet sites to AFN were 66.8F (Rindge, NH at 1200 feet), 67.4F (Rindge, NH at 1100 feet), and 68.0F (Ashburnham, MA at 1100 feet)...I did see one closer reading west in Fitzwilliam, NH at 1100 feet of 70.2F, but it wasn't supported by the other Fitzwilliam site with a Davis that recorded a cool 64.1F high temp...also at 1100 feet. KAFN is at 1040 feet. KORE to their southwest but at a mere 550 feet also produced a high of 71F.

The reason I bring it up is it has been happening for at least the past couple months. I first started noticing it in summer, but perhaps it started a bit earlier. They never used to run warmer than KORH except for in unique setups.

Did you see the MADIS error analysis graph I posted the other day? It appears there was a step change sometime in February.

Looks like the cooldown is now pushed back until the 25th or so

There was never a big cool down progged in these parts until maybe late month and even that isn't entirely impressive here. Heart of the cold is west, but we'll get a piece of it. Maybe a bigger piece breaks off and we get a sharp 1 or 2 day cooldown amid all this.
