It may not be much – just 0.1 inches ( 0.25 cm ) – but it ’s the first mensurable snowfall Tallahassee , Florida , has seen in 28 year .
The coating of white stuff over some northerly parts of the Sunshine State , as well as southerly Georgia , came good manners of a storm system that is require to quickly tone up as it moves up the East Coast , bringing warm malarkey and potentially heavy snowfall . Because of this " bomb calorimeter cyclone , " as it is known , prognosticator have issued winter storm warning from northerly Florida to New England , a rare happening .
On Jan. 3, Floridians got a rare glimpse of snow falling on palm trees.
Florida is typically more synonymous with the snowbirds who flee glacial northern wintertime for the state ’s balmy beaches . But Florida , particularly its northern orbit , can for certain see temperatures drop when cold air invades from the north , as it has over the last few days .

Typically , though , such cold air means conditions are too dry for any snow to fall .
And when there is Baron Snow of Leicester , it commonly has n’t been cold enough for long enough for roads and other control surface to be sufficiently chilly for flakes to stand by .
" It has to be cold enough to pile up , " Mark Wool , the warning coordination meteorologist at the National Weather Service ( NWS ) in Tallahassee , told Live Science . " That ’s why it ’s so rare . "
But with this low - pressure system developing off the Atlantic coast of Florida , wet was pulled far enough westward to provide the fuel for C. P. Snow and the sphere — like therest of the easterly half of the country — has " had an unusually long stretch of frigid weather , " he said . So the snow " started sticking in good order away . "
The snow lasted only about an hour and hit a bare 0.1 inches at the NWS office and the airport ( the official post for record keeping ) , though higher total were reported farther north and east .
Officials closed portions of the main road , and school were strike down out of an abundance of caution , Wool say , as suspend rain that come before the snow made some roadway slick .
But the Lord’s Day has already come out there and temperatures haverisen above freezing , so " it ’s already melting away , " he said .
The last metre Tallahassee had measurable snow was in December 1989 , when 1 column inch ( 2.5 cm ) fell on the metropolis . Since then , they ’ve had some traces of blow and accumulations of ice , most recently in 2014 .
The most nose candy Florida ’s capital has ever seen was 2.8 inches ( 7.1 cm ) , which fell in 1958 . One of the rarest snowfalls in the state of matter ’s history came when snow flurry fell across South Florida — even at Miami Beach — on Jan. 19 , 1977 , the first time that had happened in commemorate chronicle , according tothe NWS . That snow also hail after aprolonged blast of Arctic air .
Prepare for bombogenesis
As the current tempest develops , its central press is expected to speedily meet the criteria for a cognitive operation called bombogenesis , when pressure omit at least 24 millibars in 24 hour . ( Standard atmospheric pressure , or the weightiness of the air at sea level , is about 1,013 millibars ) . That usurious drop causes breeze to come rushing in to satiate the void , which make strong wind .
The tempest is also expected to drop potentially heavy snows along theatrical role of the East Coast , though exactly how much snow will fall will reckon on how closely the storm hugs the coastline . [ 6 Unexpected Effects of Climate Change ]
Snowstorms and dusty snap — particularly in rare place like Florida — are often used by climate change agnostic in attempts to debunk the construct of man - make clime change , that is , the established ascension in Earth ’s temperatures because of heat - pin down greenhouse gases . But both will continue to occur even in a warmer world , since Arctic breeze will remain comparatively cold compared to down in the mouth latitudes and wintertime will still occur . However , cold elasticity that contribute to book lows will become less and less potential as Earth ’s feverishness runs ever higher . Record highs have already been progressively outpace record Low in the U.S. , presently by about 2 to 1 . And a2016 Climate Central research reportfound that winter precipitation was increasingly hang not as nose candy , but as rainfall in many states across the country .
Studies in recent years have show some remarkable warming - relate Baron Snow of Leicester trend , though . For instance , areas around the Great Lakes are in prime lake effect snow territory , and snow amounts there may really increase for a while , harmonize to inquiry and late tendency .
The lake gist find when a sudden rush of cold air meets the still warm , unfrozen Ethel Waters of the lakes , typically in previous dusk . The urine evaporates into the inhuman air and falls as C downwind . As lake temperatures rise , vaporisation increases , which means moremoisture is useable to fuel snowswhen an Arctic good time comes along .
But eventually , temperatures will become too warm to suffer coke , particularly in the fall . Warming could push the prime lake essence season afterward into the winter as the lakes remain warmer longer .
A2014 studythat looked at how warming might affect the bad Charles Percy Snow – the Snowpocalypses and Snowzillas – found that extreme snowfalls might describe for a bigger balance of all snows for a sentence . The rationality is because extreme snows happen in a narrow , goldilocks aster - esque temperature isthmus : if it ’s too warm it rains , and if it ’s too cold , the region is too dry for whopping snow totals .
As temperatures increase overall , they eat away at the kitchen stove for all snow to organise quicker than the one for extreme snow , so blizzards drop off less quickly than snows overall .
What ’s more , snow could be wiped out at the same rate in regions with mild temperature that seldom see snow . So , savor those snowflakeswhile you could , Florida .
