Florida Freeze - January 18, 2018 (advective)


RedRabbit

Recommended Posts

This thread is to document temperature data from the Florida freeze occurring on January 18th, 2018. Temperatures were generally about 1 standard deviation below the average annual low for most locations. Winds were approximately 5-10mph from the NNW and there were no reports of frost.

This freeze was unique because it was advective rather than the much more common radiational. Due the rarity of advective freezes there's not a lot of local temperature data so I decided to document it in the interest of later being able to reference how local microclimates performed under these conditions.

The images that follow were taken from Wunderground.com between ~7:05am and ~7:30am. These may not represent the absolute low for all locations. Additionally, some weather stations have significant measurement error so stations appearing to be warmer for no apparent reason (no coastal or urban influence) should be assumed to be reporting spurious data.

@RedRabbit Some nice artwork! :)  I liked the close-ups of the metro areas.  In the Lakeland close-up, the station near Edgewood Drive reported 28F, and isn't that far away.  That lets me know my weather station is within reason.

Excellent, fascinating work! I live in the center of Cape Coral and my simple battery-powered thermometer sensor's record of 34.2F was spot on. Thanks for this info.

I know our state has experienced colder than normal weather this winter. However, when you consider how hot it is virtually 300 days a year just North of the Old Monkey Jungle, can a high temperature of 63F with a low of 43F be considered a climatic disaster? The ocean temperature remains in the low 70’s! I am thankful of a few cool days this time of year because I know what comes next. At the same time, I really do not mind that either because sweating is healthy and the trade winds make it bearable.

Great Post! Thanks for including Daytona Beach Shores/Ponce area. With this freeze beachside was only a couple degrees warmer. Normaly 6 to 10 warmer. There is major damage over here.

Thank you for posting. This makes me feel a little better about my spot in intracoastal Jacksonville. Waking up to a low of 26 really busted my bubble, as like many here, I thought I should've been a little warmer than the surrounding areas due to the water. However, the freeze was at it's worst a couple of hours after a negative low tide, which in my case, I'm wondering if it allowed the temps to drop an extra couple of degrees.
