A potent storm system was moving across the central United States on Saturday and will reach Florida by Sunday.
Conditions range from severe weather in the lower Mississippi River Valley and southeast to blizzard conditions in the Northern Plains and upper Midwest.
In the Tampa Bay area, the timing looks to be sometime from late morning to mid to late afternoon. Storms will hit the coast first and then move inland. Some will be strong to possibly severe.
The main threats Sunday will be heavy rain, frequent lightning and potentially damaging wind gusts.
After the cold front, the weather will be much cooler Monday as highs will struggle to reach 70.
Any fog will start dissipating at daybreak Sunday as winds start increasing. There will be some sun in at least the first half of the day.
The winds will start ramping up Sunday morning, and it will be warm and very humid.
Some thunderstorms may pop up early Sunday afternoon in inland spots along the fast-moving sea breeze.
Some of the storms could be strong in the afternoon. Then, a line of thunderstorms will move in from the Gulf. The rain chance is 70 percent. It will be windy, with a risk of stronger winds with the storms.
Boating conditions will be hazardous all day Sunday into Monday.
Behind the front, there will be another blast of cooler air moving in on Monday. High pressure builds in with dry air and breezy conditions. The high will stay near 70 with mostly sunny skies.
Monday night, the lows will be in the low 50s. Tuesday will be sunny with low humidity and afternoon temperatures in the low to mid 70s. Winds will be lighter as high pressure builds in. Mid to late week, high pressure moves into the Western Atlantic with a warming trend and moisture returning. Winds will be light from Tuesday into Friday. Highs return to the 80s Wednesday through Friday.
Tuesday morning will be chilly with 40s and 50s before warmer weather returns for the rest of the week.
