FXUS62 KTBW 091841 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 241 PM EDT Thu Jul 9 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Near record high temperatures with high heat index values through Friday. - Drier air moving into the area will limit rain chances through Friday. && .DISCUSSION... Issued at 233 PM EDT Thu Jul 9 2026 The continued advancement of the Saharan Air Layer into Florida will keep the peninsula dry and hot today. Heat advisories are in effect for our region, with heat index values of up to 110 expected in some areas through this afternoon. There will be little to no relief for this heat, as the SAL will keep moisture relatively low and precipitation chances slim, although an isolated shower or storm is still possible. The heat associated with this dry spell will reach near-record levels. As the Saharan dust moves out temporarily tomorrow and into Saturday, we can expect to see a slight return to our normal summer pattern. Tomorrow afternoon, slightly higher PoPs will reach into SWFL, bringing some isolated to scattered showers and thunderstorms. Storms that do develop a chance of strong, damaging winds. SPC has placed a large area of the CWA in a marginal risk (1 of 5) for severe storms. Saturday, higher PoPs and scattered thunderstorms return to much of our area, primarily south of the I-4 corridor. Beginning Sunday and into next week, a trough will set over northern Florida, which will keep the highest levels of moisture and precipitation north of the I-4 corridor. Areas south of I-4 will see continued heat index values exceeding 100, as cloud cover and precipitation may be limited. && .AVIATION... (18Z TAFS) Issued at 233 PM EDT Thu Jul 9 2026 VFR conditions prevail. Winds become light and variable overnight.

Issued at 233 PM EDT Thu Jul 9 2026 The Saharan dust over the area will continue to keep the mid levels dry today, which will limit shower activity. However RH values remain above critical areawide.
