Time to Say Goodbye to Winter

Well... if you go back and look at the past few months... I don't think that winter really even visited us very much at all.

I think it's necessary to at least say goodbye to winter at this point. Maybe if we all say goodbye... winter will come back for one last hurrah. It's like at the end of a scary movie and the killer comes back one more time for another scare.

Spring will arrive at 1:14am on March 20th. If you are reading this at 1:15 or anytime later... Welcome to Spring :)

The forecast looks nothing like Spring... it looks warmer! Daytime highs will run in the 80s to round out the work week. What we are experiencing out there right now is usually what we see in June. The average high for the month of June is 80.8 degrees. We have beyond that in many cases and we'll be beyond that for the beginning of Spring.

A "Wall" (See graphic below) in the atmosphere is keeping big players awy from Kentucky right now. The area of high pressure will hold off any major rain maker until the weekend. That's the same time that we will see highs drop quite a bit. However, it looks like we'll still be around 10-15 degrees above average for this part of March. This is just a great pattern for the folks across KY to be experiencing in March. Even with the cool down in the cards.

That high keeps an invisible boundary in place. Each time a storm system makes a good run at it... it weakens it a little more. Eventually the "Wall" will breakdown and allow for these storms to come rolling through our region.

As I mentioned up there... Spring is here... but how did it get here?

There are two equinoxes every year – in March and September – when the sun shines directly on the equator and the length of day and night is nearly equal. Seasons are opposite on either side of the equator, so the equinox in March is also known as the "spring equinox" in the northern hemisphere. However, in the southern hemisphere, it's known as the "autumnal (fall) equinox".

Why is it called the equinox?

On the equinox, night and day are nearly exactly the same length – 12 hours – all over the world. This is the reason it's called an "equinox", derived from Latin, meaning "equal night".

However, even if this is widely accepted, it isn't entirely true. In reality equinoxes don't have exactly 12 hours of daylight

On these two days, the geometric center of the sun is above the horizon for 12 hours, and one might think this would indicate that the length of the day (hours of daylight) would be the same.

However, ‘sunrise’ is defined as the instant when the upper edge of the sun's disk becomes visible above the horizon – not when the center of the sun is visible. In the same sense, ‘sunset’ refers to the moment the upper edge disappears below the horizon. At both instances, the center of the sun is below the horizon, and therefore the equinox day lasts a little longer than 12 hours.

The March equinox occurs the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. This happens either on March 19, 20 or 21 every year. On any other day of the year, the Earth's axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth's axis doesn't tilt neither away from nor towards the Sun, like the illustration shows.
