DISCUSSION
Issued at 316 AM EDT Fri May 1 2026

An upper level cutoff low centered north of the Great Lakes will linger through the weekend as a shortwave rotates around the base of the low into the eastern US. At the surface, a stalled frontal boundary is holding north of Florida today, with westerly flow keeping temperatures in the mid to upper 80s along the coast, but allowing afternoon highs to climb into the low to mid 90s over the interior. As the shortwave digs south on Saturday, the surface front will start to push into the Florida Peninsula, bringing numerous to widespread showers and thunderstorms spreading south through the forecast area Saturday and Saturday night. A few strong to severe storms will be possible on Saturday, with damaging wind gusts and hail the greatest threats. Rain will then slowly clear out from north to south Sunday and Sunday night as the front pushes into the Straits of Florida and stalls out. Storm total QPF continues to trend downward, with 5-day QPFs now around an inch or less across the area.

In addition to the rain threat, winds will also increase ahead of the front, bringing breezy conditions and a high risk of rip currents to the area on Saturday. The front will also bring a brief cooldown on Sunday, with highs running several degrees below normal and morning lows dropping into the 50s over the Nature Coast. Temperatures will then quickly warm back up to well above normal by the middle of next week as high pressure fills back in.
