Elevated Winds and Seas Continue through Saturday Morning across the Gulf of Mexico
Elevated winds and seas will continue for portions of the Gulf of Mexico through Saturday morning. A second area of low pressure is forecast to move across the region on Friday, allowing for continued elevated winds and seas. Northerly winds of 30-35 knots with gusts in excess of 45 knots are forecast across northwestern portions of the region. In southwestern and eastern areas, winds may gust in excess of 50 knots. Seas of 7-10 feet are expected near the shore and 10-15 feet in deeper waters for most areas. In southern portions of the region, seas of 14-18 feet and locally higher seas in excess of 20 feet are forecast.
Thunderstorms for Central Florida on Friday
A stalled cold front will finally begin moving across Florida on Friday, allowing for a risk for strong to severe thunderstorms on Friday. Ongoing cloud cover will likely limit the intensity of the storms, but a few stronger storms will have the potential to produce severe winds and hail. The threat will begin during the evening and continue into the nighttime hours as the front progresses southeastward.

SPC Convective Outlook for Friday
A Look Ahead
Heading into the weekend, a weak area of low pressure may bring some light snow to portions of the Great Lakes on Saturday. Snowfall amounts of 1-2 inches are expected. As this area of low pressure moves eastward on Sunday, snow may develop across the Northeast; accumulations currently appear to be light. Early next week, another area of low pressure will bring light snow to the Great Lakes and the Northeast. Snowfall amounts of 1-2 inches are currently expected. As an area of low pressure begins to stall out across the Northeast and strengthen Tuesday into Wednesday, some significant snowfall totals will be possible for the Northeastern US. Models are indicating the potential for snowfall amounts in excess of 6 inches of snowfall during the duration of the event. The heaviest totals will be along the US/Canada border, as well as for the areas of New York bordering the Great Lakes where lake effect snow is forecast.
