Area forecast discussion 
National Weather Service Tampa Bay Ruskin Florida 
947 am EDT sun may 19 2013 


Update... 
quiet morning across the region with the weak pressure gradient 
continuing as high pressure ridges in from the northeast. Morning 
tbw sounding continuing to show light and variable winds in the 
low levels and therefore with daytime heating we will see the sea 
breezes develop in the next hour or two and move well inland this 
afternoon. Moisture continues to slowly increase with morning 
sounding indicating precipitable water around 1.4 inches while 
Miami is around 1.45 and Jacksonville around 1.5 inches. This 
should be enough to see some scattered convection over inland 
areas this afternoon and evening. Overall the current grids/zone 
forecast look OK with no morning update planned.

Aviation... 
mainly VFR next 24 hours. Main concern is late afternoon and 
evening thunderstorms which should remain east of I-75 except 
around pgd...fmy and rsw where activity may develop near 
terminals. 


&& 


Marine... 
weak pressure gradient will continue with rather light winds 
becoming onshore near the coast with the sea breeze this 
afternoon. Majority of convection should remain on land...but 
could see a few showers and storms drift out into mainly the 
southern waters this evening. Present marine forecast looks on 
track with no major changes planned for late morning forecast.
