Weather outlook for April 21-22 2012

An upper-level weather system is forecast to develop over the Lower Plains late this week then intensify as it moves across the Southeast U.S. this weekend. A strong surface low pressure system will develop and move east near the Gulf Coast and extreme north Florida over the weekend, while a trailing cold front move across the Gulf of Mexico and the Florida peninsula Sunday.

Prior to arrival of the squall line, there also may be several periods of scattered thunderstorm development, during the afternoon/evening hours today, tomorrow, and Friday, and most notably when a warm front lifts north through the region Saturday (isolated severe weather will also be possible with the activity on Saturday).

The strength and movement of the low pressure system is unusual for Florida during April, and would favor development of a squall line over the Gulf, which would then move rapidly across the central Florida peninsula, most likely late Saturday night or Sunday morning. Such a pattern has the potential to bring damaging thunderstorms winds, large hail, and tornadoes.
Further updates will be provided as necessary.
