yeah they were looking rough the past couple of games.

so what you're saying is let's make a thread

it got confused and thinks this is the Southern Hemisphere?

low of 28F at DCA and 36F up here at around 380' in upper NW. Not typical lol.

it's 47F at my house on 43rd St. A station along the same cross street but at 47th St (and probably about 80-100' lower) is at 33F. The hill we are on basically slopes down to the Potomac River, so I assume that is something. Also the wind is very slight out of the east - about 1.5-2 blocks east is a much more commercial area along Wisconsin Ave.

46F here and rising (most of my snow has been obliterated) while DCA is at 35 and dropping lol. Don't think I've seen that type of spread before absent it raining in one location and not the other.

this is insane lol

49.5F here. A WILD inversion going on right now around here - it's 45F here, about 4 blocks away and downhill, it's 33F lol.

you would take the maximum temperature observed from Dec 15-31 in each year from 1991 to 2020 and calculate the average.

no - it's the mean maximum temperature for the entire month. Which means - in the last 30 years, on average, the maximum temperature observed at DCA was 67F. In July, DCA's mean maximum monthly temperature is 98F - which means that's on average as hot as it gets here in July. You can see here: https://en.wikipedia.org/wiki/Washington,_D.C.#Climate The row in question in the climate table is "Mean maximum"

the human body acclimates remarkably quickly.

DCA's mean maximum for the entire month of December is 67F.

he means the average maximum temperature over the entire half month period - meaning, what's the warmest it will get, on average, for the last half of December. Mid 60s seems right - meaning, on average, DC should see one day where it hits 64F during this period.

29/18 for the day for DCA

pretty large urban/rural splits now with no wind. 27F here and rising.
