Much-needed rainfall this week for #Florida. Drought conditions wont be eliminated but this rainfall will certainly help, especially along the Atlantic coastlines. Florida’s dry season generally lasts until around May before our sea breeze thunderstorm season takes over.#wx #flwx

Tracing Tropical Cyclone Narelle’s ‘very unusual’ path to hit Australia on three coastlines It’s only the third storm system in recorded history to make landfall in three Australian jurisdictions – and the first in more than 20 years

Tropical Cyclone #Narelle made landfall four times in #Australia. The cyclone also triggered a dust storm which turned skies red in western parts of the country near Shark Bay. It’s only the third storm on record to make landfall in three jurisdictions. www.theguardian.com/australia-ne...

Photo of a bomb cyclone in early 2017. “Bomb cyclone” is a term used to describes a rapid strengthening of a powerful low-pressure system. To be classified as one, central pressure must lower 24mb within 24 hours. Chances increasing for one off the East Coast this weekend. #wx

Are trees really exploding in the severe cold? Sort of With severe cold hitting much of the country, some unusual phenomena like "exploding trees" could be on the way. Here's what to know.

An arctic front is expected to bring frigid temperatures to the middle and eastern part of the country and many are talking about #ExplodingTrees. Similar to a #FrostQuake with the loud ‘booms’ it can make. But very rare that a tree actually explodes. #wx www.usatoday.com/story/news/n...

Gravity wave clouds this morning in JAX. Nice treat to start off the 1st day of the semester. Formed when stable air is forced up & down. They produce turbulence for aircraft. My meteorology students will have to wait until our Mountain Weather lecture to fully appreciate them.
