National Weather Service Melbourne
Impact Weather Briefing
For Potential Severe Weather on Sunday
January 22, 2017
Issued: 10:00 AM, Thursday, January 19, 2017

Event Overview: A strengthening low pressure system will move across the southeast Sunday, dragging a cold front over the Peninsula and increasing the threat for severe weather. Confidence of an organized squall line moving quickly across east central Florida is increasing, focused on Sunday afternoon/evening and pushing offshore the Treasure Coast before midnight. Additional isolated strong to severe thunderstorms could develop ahead of the main squall line during the day on Sunday.

Impacts: The main threats from thunderstorms will be damaging wind gusts, large hail, frequent cloud-to-ground lightning strikes, and torrential downpours. Atmospheric conditions will support a threat for isolated tornadoes, especially within storms that develop ahead of the main squall line.

Hazardous marine conditions will develop late Saturday out ahead of the front and continue through early next week, with a period of gale conditions possible offshore Sunday evening through Monday evening.

Timing: Some uncertainty in exact timing remains, but as of this morning, the greatest threat for severe weather will occur Sunday afternoon into Sunday evening as the main squall line moves through east central Florida. A threat for strong to severe storms may develop out ahead of the squall line as isolated thunderstorms develop during the day on Sunday. More specific timing will be provided as the system draws closer to the area.

Areas Affected: All of east central Florida, with the highest threat for severe weather along and north of the Interstate 4 corridor.
