All Activity

The LGA ASOS is within a few hundred feet of the bay. So this keeps the high temperatures cooler than stations further south. Low temperatures a pretty similar in Queens.

I think he meant JJA vs June 20 - Sept 20 our weather lines up with astronomical summer not met summer. At least the first three weeks of September typically have summer weather.

Enhanced risk of severe thunderstorms today I guess it’s possible for a tornado watch today starting around 1-2 pm. Looks like we have a difluent split in the flow which also probably means isolated to scattered strong activity rather than a squall line.

In San Diego they get a lot of sun… here? Not so much…

Weren't you just arguing that our seasons match up with the astronomical dates?

Not a single cloud in the sky here.

How much does population density have to do with this? I've been to interior Queens and it's always hotter than the surrounding area, I put it down to increased traffic and higher population density plus those subway vents are always emitting hair dryer levels of heat ugh. It's hotter in the summer AND in the winter. It doesn't feel natural, but artificial because of the environment there.

Southeast sea breeze already doing its thing here. Gonna be a beautiful beach day if you took off. Should put a chokehold on any potential pop-up storms from migrating to the Jersey coast. We'll see what the potential squall line does later.

Main reason why met seasons don't line up as well here than actual seasons. Thermal lag.

Ding, ding....thermal lag

why does LGA consistently run warmer on overnight lows and almost always are the last ones to get their first freeze? I feel like it is a much more artificial climate than either the Park or JFK, who get their first freezes before they do.

that might be why July is our hottest month, similar to how January might be our coldest month because of that lag.

Didn't we get that in July 2012?

LGA has been running cooler than the micronet stations away the water influence in Queens such as Corona. Plus the maximum compressional warming in NYC occurs closer to interior Queens. Their lows aren’t any warmer than the other Queens stations.

He sure is. Here is a screenshot from the timeanddate site for Manhattan which clearly shows the difference between day length and sunrise and sunset times changing

I realized I actually confused it with the equinox/equilux lol. I read that fascinating article I just posted last year, our equal day / equal night (equilux) is typically around the 26th of March and September.

That’s kind of what I’m thinking/hoping as well.

exactly the sunsets around 8:30 till Jul 9th then slow decline - overall daylights minimal decline is attributed to later sunrise till then.

No you are confusing latest sunset and longest day. The longest day is always on the solstice. We peak tomorrow in Manhattan at 15h5m38s, we lose a second by the 21st. By the 26th we have lost a full minute. Same as winter: https://sunrise-sunset.org/a/why-the-shortest-day-is-not-the-day-with-the-earliest-sunset-or-latest-sunrise.

I wonder if space exploration will spur advancements in other areas, including climate and weather science (this has happened before.) Perhaps this will encourage greater investment. If we establish space colonies, weather prediction will become important on these worlds too

good self-awareness there!

Nah. Keep going. Nothing interesting about summeh weather.

You can see on the 12z HRRR how an initial cell kicks off an outflow boundary and then new cells fire on that this afternoon. Not saying that’s exactly what will happen, but it is cool to see those processes on the models.

https://www.timeanddate.com/astronomy/equilux.html This article explains why day and night aren't equal on the equinox too. Equinox—Close, but Not Quite Equal Many of us think that an even balance of day to night happens during an equinox. After all, the word translates as “equal night.” So, a little confusion is understandable. But there’s a subtle time difference between an equinox and an equilux. Approx. equilux dates Latitude March September 60° North Mar 18 Sep 25 55° North Mar 17 Sep 25 50° North Mar 17 Sep 25 45° North Mar 17 Sep 25 40° North Mar 17 Sep 26 35° North Mar 16 Sep 26 30° North Mar 16 Sep 27 25° North Mar 15 Sep 27 20° North Mar 14 Sep 28 15° North Mar 12 Sep 30 10° North Mar 8 Oct 4 5° North Feb 24 Oct 17 Equator No equal day and night 5° South Apr 14 Aug 29 10° South Apr 1 Sep 10 15° South Mar 28 Sep 14 20° South Mar 26 Sep 16 25° South Mar 25 Sep 17 30° South Mar 24 Sep 18 35° South Mar 24 Sep 19 40° South Mar 23 Sep 19 45° South Mar 23 Sep 19 50° South Mar 23 Sep 20 55° South Mar 23 Sep 20 60° South Mar 22 Sep 20 Equal Light “Equilux” is drawn from the Latin terms for equal (equi) and light (lux). So how do we find out which dates fit the description and qualify as truly equal day and night? To measure the day/night split in a 24-hour span, astronomers use common definitions of sunrise and sunset. Simply put, sunrise is defined as when the first bit of the Sun’s disk appears and sunset is when the last bit of the disk vanishes. Calculating the length of day between those two moments, we find that two dates every year reach equilux in most latitudes. In the Northern Hemisphere, these happen a few days before the spring equinox (vernal equinox) and a few days after the autumn equinox. South of the equator, it's the other way around. A location's equilux dates depend on the latitude (see table). Locations on or near the equator never experience equal day and night. Imagine a Disk But why aren’t day and night of equal length at an equinox? To answer that question, it helps to think of the Sun in two different ways—as a disk and as a point. To pinpoint the days of equilux, the Sun is considered a disk, and we measure daytime from the first appearance of the Sun’s disk to the last bit slipping below the horizon. A Point at the Center of the Sun To calculate an equinox, on the other hand, the Sun is thought of as a single point, set in the center of the disk. An equinox occurs when the subsolar point—the spot on the Earth directly beneath the Sun—crosses the equator, equally straddling the Southern and Northern Hemispheres. On those days, the center point of the Sun indeed rises and sets 12 hours apart. But since we measure sunrise and sunset by thinking of the Sun as a disk, the top edge of the Sun appears a little earlier and sets a bit later than the center point. This difference creates a few extra minutes of daylight on the date of an equinox at most latitudes.

Pretty morning out if Amazon dews are your kink
