Heads up‼️ Hottest Ever?! It’s genuinely possible. No exaggeration to say that the severity of the #heatwave that the Eastern US is about to experience will be cruel and grueling for days! 100s of record highs, some neck and neck with all-time records, in the East Coast cities! And peak heat index numbers near 115. Lasting right into the weekend.

Extreme Atmospheric Dance 🕺 Watch how a record shattering September Heat Dome across the US East, helps spawn a strong upper level low over #Florida this weekend trapped south of the dome. Under the heat dome hundreds of heat records will be broken, with heat index numbers up to 110. In Florida the upper level low may help cause some severe thunderstorms with hail this weekend. This is NOT a tropical system. #heatwave

100 MPH Hurricane Killing Peak Wind Shear forecast in the #Caribbean . Unreal for summer, but this is no ordinary summer. The strongest El Niño on record is flexing its muscle 💪 and overpowering the Atlantic. Anything that tries to develop would be torn to pieces. If this continues, it would be one of the quietest Atlantic hurricane seasons on record. #hurricane #elnino

No, your eyes are not deceiving you! Next week's cold blast is going to be “near” historic in #Florida for early November. The models are very aggressive and if they are right we may tie or break records set ~100 years ago. These are wind chills for Tuesday morning BUT it is not out of the question that North FL will see actual low temps near freezing next Tuesday and Wednesday mornings. Fire up the fireplaces! You don't have one? You have a week to get it :)

Just watch how gargantuan this storm is. I still can’t get over it. In terms of girth, it’s def in the top 5 that I recall. This will impact 2/3rds of the nation and half of the country in a big way. Longevity too, with us Friday-Monday! And the brutal cold that follows. 🥶 Disruption deep into next week! #Snow #ice #storm

Europe is melting! The size, intensity, and longevity of this #heatwave is enormous. Peak temperatures will reach 45°C / 100-115°F this week in #France . You are looking at temperature anomalies in the cloud layer over the next 2 weeks, which peak at +20°C. #Europe is Earth’s fastest warming continent, and European heat extremes are increasing faster than models project they should, likely due to changes in steering flow. In a rapid attribution study by Climameter it is estimated that #climatechange has made this June heatwave up to 4°C hotter (7°F) than it would have otherwise been without warming.

When I look at this jet stream the word insane comes to mind. It's even more astonishing when you consider it's mid June! This configuration, likely enhanced by climate heating, is fueling a record heat dome so extreme that even experts are astonished!

What if #Milton went 25 mi north? Disaster for #tampabay! Milton’s eye went south of the bay and winds on north side forced 2-5 ft of water out. Reverse surge. But landfall 25 miles north would have changed fate as 15 ft of surge would have funneled into the narrowing bay. WFLA NEWS

#Hurricaneerin is hungry. It will feast on hot water up to 88 degrees. After using this heat to power its engine, it will dissipate said heat. Leaving a cool ocean wake in its path, ~10 degrees lower than it found it. The water cools not just due to heat absorption, but also overturning /upwelling, wind and rain.

Heat Domes Dominate the Planet! Sound up! Typically El Niño waits until fall to impact the jet stream, but this one is supercharged. That means the heat in the Tropical Pacific is already helping to reorganize atmospheric waves, leading to persistent and intense heat domes in North America with downstream impacts in Europe. Those heat waves are of course significantly boosted by the long term warming trend. #elnino #heatwave #heatdome #extremeweather

Watch #Melissa meander on a path right through some of the hottest (deep) waters on the planet, powering one of the strongest hurricanes ever, then leave a cool wake behind as it turns hot water into power to charge its rain and wind. The #caribbean in October is notorious for monster hurricanes and Melissa literally moved over the hottest waters not just in the Atlantic but also in the entire Caribbean. How it ended up there is part luck, part climatology, and - in a local sense - partly that storms without steering can sometimes be tugged towards areas with the greatest heat/ instability. #hurricane #fyp #jamaica

This may be hard to believe given how cold it’s been, but the coldest air of the season is still to come in the Northeast this weekend. Wind chills to -30°F or lower Sunday morning. -20 in NYC!! Holy moly. #cold #winter #ArcticBlast #snow

Can’t stop. Won’t stop. The models keep insisting on historic cold as the huge Canadian Polar Vortex pays the Eastern US a visit! A pool of record breaking cold 850mb temps and record breaking 500 mb heights (for early-mid Nov) will do a “fly by” Monday-Wednesday as actual surface low temps fall below freezing in the SE US, 30s as far south as Central-North FL!! 40s south of I-4, 50s deep into South FL. #Florida #ColdFront #Freeze #Snow #Winter

The Arctic flood gates are opening up, as a strong & warm (relatively) block grows over Greenland. That warmth will shove the frigid Polar Vortex south, with multiple cold plunges in the batters box for the next 10-15 days in the Midwest, Great Lakes, Northeast and Mid-Atlantic. The chilly air will visit the Deep South and #Florida periodically too.

El Niño is born! Destined to be the biggest in 150 years +?? NOAA declares: El Niño Advisory This morning conditions in the Eastern Pacific met the criteria for El Niño. This means Sea Surface Temps reached a certain level above normal, and the ocean and atmosphere “coupled” meaning they are now working in tandem to produce impacts. This event is widely advertised by models to be potentially the strongest on record. El Niño takes very hot water stored in the deep tropical west Pacific, pushing it east and up to the surface, lofting that heat into the atmosphere, which supercharges weather events and throws the climate off-kilter. This typical means more intense heatwaves & floods, but also it restrains the Atlantic hurricane season. So its impacts are both good and bad. One thing seems virtually certain: the heat released into the atmosphere will make for some unprecedented events through 2027, and on top of longterm warming, the hottest global temperatures in many tens of 1000s of years. #ElNino #florida #storm #heatwave #flood #drought

Some rare and remarkable processes are taking place this week, that we are not likely to observe for a long time! These 2 Atlantic hurricanes are closer than any since at least the 1960s. They are now connected - in each other’s orbit, pivoting. Stop 1. Notice the calm area at the pivot point between the two storms caused by sinking air. Stop 2. #Humberto dissipates and #Imelda cannibalizes its moisture and energy, passes over #Bermuda, grows, then heads out to sea. (2 hurricanes can NOT merge both as hurricanes. One must die or transition extra tropical first) Stop 3. Imelda meets a frontal boundary where it scales the front and is accelerated NE.

This is the definition of compound, concurrent heat extremes! What you're looking at is the pressure pattern & wind flow at the 500mb level (5600 m, 18K ft). This is why Death Valley hit 129, the Med may hit 118, Iran heat index 152F and China hit an all-time heat record of 126.

Lucky us… The Earth’s biggest Heat Dome will be right on top of Florida and the Southeast US this Weekend! Highs near 100, Heat Index up to 115° Stay cool… #heatwave #heatdome #Florida

‼️ In house Hi Res Model escalates this weekend. GRAF Indicates #Bertha by early week as the storm drifts west away from Florida into the #Gulf. This model is very good, but I emphasize this is an incredibly tough forecast, and it may be wrong. I find it tends to spin things up too fast, and we are not yet in the GRAF wheelhouse of inside 48 hours. I only post this because it’s 3 days from now and as we go into the weekend I don’t want folks sleeping on this, and I want to be transparent with ya’ll. It’s nothing to be concerned about, just something to be aware off. Right now NHC development chance is at 30%. Otherwise on/ off downpours through the weekend.
