Meteorologist Robert Speta defines and tracks the dynamics behind what a lake\/sea effect is and how it can be seen around the First Coast. <\/p>\n

JACKSONVILLE, Fla. \u2014 Snow is rare along the Florida Coast, but under specific conditions, it can take place!\u00a0<\/p>\n

In even rarer conditions, we could see \u201csea effect snow\u201d offshore.<\/p>\n

Now, lets stress the odds of this happening are low, but theoretically possible for coastal waters. But this setup offers a useful opportunity to explain how lake-effect and sea-effect snow develop and why it occasionally sparks curiosity even in subtropical regions.<\/p>\n


\nWhat is lake-effect (or sea-effect) snow? <\/p>\n

Lake-effect snow forms when very cold air moves across a much warmer body of water. The temperature contrast causes rapid evaporation from the water\u2019s surface. As that moisture rises into the colder air above, it quickly condenses into clouds and, in the right setup, produces snow that falls downwind of the water source.<\/p>\n

When the same process occurs over an ocean rather than a lake, it is referred to as sea-effect snow.<\/p>\n

This phenomenon is most common downwind of the Great Lakes, where Arctic air masses frequently pass over relatively warm freshwater, producing narrow but intense snow bands that can drop heavy snow in localized areas.<\/p>\n

\nCould something similar happen near Florida? <\/p>\n

While Florida lacks the cold climate typically required, the physics behind the process still apply anywhere cold air flows over warmer water.<\/p>\n

During rare, intense cold outbreaks, air temperatures along the First Coast can dip near or below freezing while ocean waters offshore remain in the 50s or even low 60s. That temperature difference is sufficient to trigger evaporation and cloud formation.<\/p>\n

In theory, if cold air were to move steadily over the Atlantic waters, the Intracoastal Waterway, or even the St. Johns River, shallow convective clouds could form \u2014 similar in structure to lake-effect snow clouds, though much weaker.<\/p>\n

Some guidance does show this but it is weak and reality is if it did form it would likely stay off shore to the east. While the chances are remote, the discussion highlights how the same physical processes that drive intense snowstorms near the Great Lakes can, under the right conditions, briefly appear even in the Deep South and off of the First Coast.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"Meteorologist Robert Speta defines and tracks the dynamics behind what a lake\/sea effect is and how it can…\n","protected":false},"author":2,"featured_media":137072,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[116,118,117],"class_list":["post-137071","post","type-post","status-publish","format-standard","has-post-thumbnail","category-jacksonville","tag-jacksonville","tag-jacksonville-headlines","tag-jacksonville-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts\/137071","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/comments?post=137071"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts\/137071\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/media\/137072"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/media?parent=137071"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/categories?post=137071"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/tags?post=137071"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
