Busy flight day above #SaintAugustine. #Contrail Weather. Created when planes fly in cold and humid atmospheric conditions and ice crystals form around the particles emitted from the engine. #wx #flwx

The National Hurricane Center completed their post season analysis of #Hurricane #Melissa. Maximum winds were found to be 165kts (190 mph). This would tie with Hurricane Allen (1980) as the most powerful Atlantic hurricane based on wind speeds. #wx www.nhc.noaa.gov/data/tcr/ind...

As of 1PM eastern. #Tornado Watch has been extended east to include parts of Northeast #Florida & Southeast #Georgia. Strong squall line moving eastward today. Currently in Panhandle. Isolated tornadoes, strong winds, & small hail likely. Have multiple ways to receive alerts #wx

Small angel echoes near Green Cove Springs this morning. These circle-like echoes can typically indicate a scattering of biological entities such as birds, insects, or airborne particulates. #wx

Groundhog Day live updates: Punxsutawney Phil predicts 6 more weeks of winter Tens of thousands of people are gathering for Punxsutawney Phil, a groundhog that lives in a tree stump, to predict if the already long and cold winter across much of the United States will go on for ...

Six more weeks of winter! #PunxsutawneyPhil saw his shadow this morning. Phil has an overall accuracy rate of about 40% since he started forecasting in 1887 😉. #wx #GroundhogDay apnews.com/live/groundh...

Can confirm. It’s freezing 🥶. #flwx

Keep your eyes to the sky Northeast #Florida. Some flurries beginning to fall. #wx

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

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.

Magnitude 6.5 #earthquake struck the southern Mexican state of Guerrero, near #Acapulco, this morning. There is no tsunami threat from this earthquake.

Happy New Year! 🥳 First sunrise of 2️⃣0️⃣2️⃣6️⃣ in beautiful #SaintAugustine. Looking forward to another exciting year and keeping my eyes to the sky. #wx #flwx

Beautiful #sunset this evening in #SaintAugustine. “Pink at night, sailor’s delight.” Dry, plenty of sunshine, & cold temps continue for New Year’s Eve as high pressure builds in from the west delivering cold northerly winds. Cold Weather Advisory & Frost Advisory in effect. #wx #flwx

Dec 21, 2025 at 10:03 AM eastern is the #WinterSolstice. The shortest day and longest night of the year and signalling the astronomical start of #Winter in the Northern Hemisphere. After the Winter Solstice the day light starts to get longer.

The 2025 Atlantic #hurricane season ends today. 13 named storms, 5 hurricanes, & 4 major: a near-normal season. Three Cat 5 storms: Erin, Humberto, & #Melissa. Melissa producing a world record wind gust (252mph). No hurricanes made landfall in the US for the 1st time since 2015. #wx

Cloud-top temperature and height, helping to determine a storm's intensity. Colder, taller clouds (often shown as white, black, or red) indicate more powerful thunderstorms.

Confirmed world record. #Hurricane #Melissa produced a wind gust reading of 252mph. A Hurricane Hunter dropsonde recorded this gust at 657 feet above the sea, breaking the old record of Typhoon Megi (248 mph in 2010). #wx

Cold Weather Advisory in place for much of Northeast #Florida. Not everyday that we see wind chill values in the lower 20s, especially in November. Even wording of hypothermia & frostbite. Bring in all pets and sensitive plants tonight. Gradual warming expected after Tuesday. #wx

Coldest temps of the season arrive Monday & Tuesday for parts of North #Florida. Cold front moving through tonight with high pressure building in behind bringing cold northerly winds. Freeze Watch in place for Monday night & into Tuesday morning. Bring in pets & sensitive plants.

Seven years later and I am still rocking my #hurricane graduation shoes. #wx

It’s not #Halloween without the annual #hurricane pumpkin. Focused on the stadium effect for the eye this year. Have a Happy Halloween everyone 🌀

Eyes on The Bahamas today. However, #Bermuda now under a #Hurricane Warning. #Melissa will be picked up by a cold front from the north pushing it towards Bermuda Thursday. A chance of intensification but strong wind shear and the cold front interaction could hinder strengthening.

#Melissa pulling away from #Cuba & approaching The Bahamas. Currently a Category 2. Land interaction has helped to weaken the winds but heavy rainfall, flooding, & surge will persist across the region today. Don’t focus on the Category, focus on protecting your life and property.

From the National #Hurricane Center regarding the landfall of #Melissa. Currently down to a Cat 4 as it carves across the island of #Jamaica. Eye is closing off but has the chance to undergo an eyewall replacement cycle and strengthen as it exits back out over water before approaching #Cuba. #wx

#Melissa has made landfall near New Hope, Jamaica, with winds of 185 mph and a barometric pressure of 892 mb. Tied with the 1935 Labor Day #hurricane as the strongest landfall on record in the Atlantic. #wx

Max winds are 185mph. Pressure 892mb. Category 5 #Melissa coming ashore in #Jamaica. Tied for the third strongest Atlantic #hurricane on record based on barometric pressure. If it reaches wind speeds of 190mph it will be tied with Allen (1980) as the strongest based on winds. #wx
