The start of meteorological fall in Seattle is cool, but warmer temperatures are on the way.
For meteorologists (and everyone else looking forward to sweater weather and all things cinnamon), the first day of fall has here, and it’s chilly.
While the first day of autumn on astronomical calendars is September 22, meteorologists start keeping records for the season on September 1, therefore meteorological fall begins on Wednesday.
According to the National Weather Service, temperatures across Western Washington were predicted to be in the 40s Wednesday morning, with some regions seeing fog or low-hanging clouds.
Fog visibility will be worst in Everett, Maryville, and Chehalis Valley, but it should clear by 9 a.m., according to Steve Reedy, a weather service meteorologist.
warmer temperatures are on the way.
Though the morning will start out cloudy, the sun will break through later in the afternoon, bringing temperatures in the upper 60s and mid-70s. By 11 a.m., Seattleites should be able to enjoy warmer weather, according to Reedy.
Temperatures will stay in the 60s and 70s for the rest of the week and into the first week of next week.
“We’re still in the middle of summer,” Reedy added.

IN 2021, WHEN WILL THE SEASONS BEGIN?
CELEBRATE SPRING, SUMMER, FALL, AND WINTER’S FIRST DAYS
When do the four seasons begin, and why do they start dates for what are the differences between spring, summer, fall, and winter? Dates for the equinox and solstice in 2021, and 2022.
are listed below, along with answers to frequently asked issues such as why seasons change, why seasons are various lengths, and what the difference is between an astronomical and a meteorological season.
WHEN DO THE SUMMER AND FALL SEASONS GET STARTED?
Each season begins with both an astronomical and a meteorological beginning. It may appear difficult, but believe us when we say it isn’t!
The position of the Sun in reference to the Earth determines the astronomical start date.
Our 12-month civil calendar, as well as the annual temperature cycle, determine the meteorological start date.

A “SEASON’S” DEFINITION
Here’s more on the differences between astronomers and meteorologists when it comes to defining seasons:
The location of the Earth in reference to the Sun determines when a season begins astronomically.Â
The beginning of each season is marked by a solstice “winter and summer” or an equinox.
‘spring and fall'{for spring and autumn}.
An equinox occurs when the Sun passes over Earth’s equator, whereas a solstice occurs when the Sun reaches its most southerly or northerly point in the sky.
The dates of the equinoxes and solstices might move by a day or two over time due to leap years, causing the seasons’ start dates to shift as well.
The 12-month calendar and the yearly temperature cycle, on the other hand, are used to determine the meteorological start of a season.
Each season, according to this definition, begins on the first of the month and lasts three months:
spring begins on March 1, summer begins on June 1, autumn begins on September 1, and winter begins on December 1. Because the start of each meteorological season does not change from year to year, climate scientists and meteorologists developed this concept to make it easier to collect weather data.
Because The Old Farmer’s Almanac is an astronomical “calendar of the heavens,” we’ve long followed the astronomical definition of the seasons based on the Sun and Earth!
Because of the fluctuating sunlight caused by the Earth’s orbit around the Sun and the tilt of our planet’s axis, temperate zones of Earth experience four seasons. The tilt causes different portions of the Earth to be exposed to more or less sunlight depending on whether we are inclined towards or away from the Sun as the Earth moves through its orbit throughout the year.
WHY WAS THE SEASONS BEGINNING DATE CHANGED?
You may recall that when you were younger, the first day of spring fell on a different date than it does now.
Over time, the dates change.
Why?
There are a number of astronomical reasons for this, but the most straightforward is that the Sun does not follow a human calendar!
Our Gregorian calendar was created to approximate the time it takes the Earth to complete one orbit around the Sun, but it isn’t exact.
It eliminates leap days from century years not evenly divisible by( 400/ such as 1700/1800/ and 2100), as well as millennium years divisible by (4,000/such as 8000, 12000).
As a result, the equinox’s and solstices’ dates might move by a day or two over time, causing the seasons’ start dates to shift as well.
WHAT ARE THE DIFFERENT LENGTHS OF THE SEASONS?
Winter may seem to last an eternity at times, but did you know that it is the year’s shortest season? (At least, that’s how it is in the Northern Hemisphere.)
Earth’s orbit around the Sun is elliptical, therefore its distance from the Sun varies during the year. We reach the point in our orbit closest to the Sun (called perihelion) in January and the farthest point in our orbit (called apogee) in July.
The gravitational attraction of the Sun is slightly stronger as Earth gets closer to it, causing our planet to move slightly faster in its orbit. Because we are traveling faster through space during that time of year, those of.
