Historic cold breaks multiple February records across Florida

Florida experienced one of its sharpest February temperature drops in recent history on February 1, as Arctic air swept deep into the peninsula and broke records across nearly every major observation site.

According to the National Weather Service Melbourne Office, morning lows either broke or tied daily records at all of their official climate stations, including Orlando, Daytona Beach, Sanford, Melbourne, Vero Beach, and Fort Pierce.

Daytona Beach, Leesburg, and Sanford all recorded −5°C (23°F), Orlando registered −4°C (24°F), Melbourne −4°C (25°F), while Vero Beach and Fort Pierce both bottomed out at −3°C (26°F). Several of these readings set new all-time February lows, replacing records that had stood since the early to mid-twentieth century.

The outbreak was caused by a dense Arctic air mass that surged southward behind a rapidly intensifying storm system over the western Atlantic. As the cyclone moved up the East Coast, strong north-northwesterly winds transported sub-freezing air into the Southeast US.

By the evening of January 31, the front had cleared the Florida peninsula, and a high-pressure ridge over the lower Mississippi Valley allowed skies to clear and winds to calm. Under these radiational-cooling conditions, surface temperatures continued to fall through the night, reaching their minimum just after sunrise.

Reports of light snow flurries accompanied the leading edge of the front in parts of the Panhandle and north Florida, although no accumulation was observed. Elsewhere, clear skies and dry air favored frost formation.

Freeze warnings issued by the National Weather Service remained in effect through February 2, covering nearly the entire state except for the southernmost coastal zones.

Agricultural monitoring stations recorded several hours below 0°C (32°F) in citrus-growing areas north of Lake Okeechobee, raising concerns about localized fruit damage, while in southern counties, residents observed cold-stunned Green iguanas falling from trees as temperatures dropped below 10°C (50°F). Frost and thin surface ice were also recorded in Palm Beach County and Indian River County.

The NWS Melbourne Office confirmed the persistence of the Arctic air mass on the morning of February 2 when it reported that “daily low temperature records were tied or broken at all local climate sites once again this morning.” Two of those readings also set new monthly records for February.

Sub-freezing air spread across southern Georgia and Alabama, where morning lows matched those of mid-winter norms for the Midwest. The event was tied to the same Arctic outbreak that produced heavy snow and dangerous wind chills across the Carolinas and the mid-Atlantic earlier that weekend.

Based on available National Weather Service and historical climate data, February 1 now ranks as Florida’s coldest February 1 since at least 2010, and among the most extensive freeze events in the past half-century.

Comparable outbreaks occurred in 1977, 1985, 1989, and 2010, each associated with strong post-cyclonic northerly flow following rapid storm development in the Atlantic.
