'Bombogenesis': What is it and why is everyone saying it?

It seems like this year's wacky weather term is "bombogenesis."

Every year, there seems to be a new weather term that grabs everyone's attention. But they're almost never new and they're always less fantastical than they sound. 

>> What is a ‘bomb cyclone’ and what will happen when it arrives?

This year's word is bombogenesis, a term that simply describes the rapid pressure drop in a storm system

While you may have not heard the term until recently, there have been many New England storms that have undergone the process of bombogenesis.

The nor'easter tracking up the U.S. coast this week will drop pressure fast as it strengthens, increasing its expected wind and precipitation. 

>> What is a Nor’easter and how does it form?

Typically, a storm with lower pressure has stronger winds and can produce intense rain or, in this case, snowfall rates. 

So now that we know this storm will drop pressure fast or undergo "bombogenesis," we are expecting some hefty snowfall and strong, damaging winds.

The wind could knock out power to many areas and cause problems with the frigid temperatures that will follow this storm over the weekend.

If you were wondering just how cold it is in and around Austin, a picture taken Tuesday morning at a Pflugerville car wash might serve as an answer:

Noelle Newton, of Houston’s Fox 7, tweeted a picture Tuesday morning showing a car wash at an HEB in Pflugerville that had completely frozen over. 

According to the National Weather Service, it was 30 degrees in Pflugerville around 1 p.m. Tuesday. The temperature in Austin was 31 degrees, with a hard freeze warning in effect till noon Wednesday.

Tuesday's deep freeze stretched across a wide swath of the U.S., from South Texas to Canada and from Montana through New England. In Texas, freezing temperatures were reported in Amarillo, Lubbock, Dallas, Austin and Houston.

The Associated Press and the Cox Media Group National Content Desk contributed to this report.

Tuesday’s low temperature shatters 120-year-old record

It’s been a very cold start with record-breaking temperatures into the new year.

In fact, New Year’s Eve tied for the record lowest high temperature at 11 degrees, the same as New Year’s Eve in 1976.

>> Closings and delays

It only got colder for New Year’s Day, which set a record for the lowest high temperature in Dayton, where the high only was 5 degrees. This broke the previous lowest high of 6 degrees in 1928.

Official records show that for January 1, the Dayton International Airport fell to 7 below zero. The record low minimum temperature for January 1 was 8 below zero, which was set back in 1968. This means we started 2018 with the second coldest morning on New Year's Day on record. 

>> Lowest temperatures since 2014 could hit this week

This morning, Jan. 2, the minimum temperature dropped to 13 below zero. This beat the old record for lowest minimum temperature, which was 5 below zero, set back in 1898.

Dew point and humidity: What's the difference?

Relative humidity and dew point are often mistaken for the same thing and can be sources of confusion. But what are the differences between the two, and which is more relevant in everyday life?

Relative humidity and dew point both give us an idea of the amount of moisture in the atmosphere; however, only dew point is a true measurement of the atmospheric moisture.

>> When temperatures drop, don't be thrifty with your heat

Relative humidity is defined by the National Weather Service as the amount of atmospheric moisture present, relative to the amount that would be present if the air were saturated. But what does that really mean In short, the relative humidity is a function of both the moisture content in the atmosphere and the actual air temperature. By itself, it does not directly indicate the amount of moisture present in the atmosphere.

>> Could Niagara Falls completely freeze?

Relative humidity is calculated using meteorological variables such as vapor pressure, saturation vapor pressure, temperature and dew point. Without explaining the equation variable by variable, we can simply state that the relative humidity is determined by how close the air temperature is to the dew point temperature. The closer these values are, the higher the humidity. The further apart these values are, the lower the humidity.

Dew point is the term that most meteorologists use to describe the amount of moisture in the air. The National Weather Service defines dew point as the temperature to which air must be cooled to in order to reach saturation, assuming air pressure and moisture content are constant. In short, the dew point is an accurate measurement of the moisture content in the air. When talking about a certain day feeling “muggy” or “sticky,” the dew point temperature is the more accurate term to use.

Must-see: Niagara Falls is a winter wonderland in these stunning photos

A cold wave is sweeping almost all of North America, and as temperatures have dwindled, we’ve seen some pretty bizarre things. But one of the coolest and most beautiful sights right now has to be Niagara Falls, where Jack Frost painted a spectacular scene that looks like something straight out of Narnia.
