Area forecast discussion 
National Weather Service Tampa Bay Ruskin Florida 
929 PM EDT sun may 19 2013 


Update... 
convection has diminished in coverage and intensity this 
evening...but lingering pockets of instability from areas that 
weren/T worked over earlier in the day continue to result in 
additional shower/thunderstorm development. Will carry 20 probability of precipitation 
across interior locales primarily east of I-75 where showers/storms 
are ongoing through the remainder of the evening hours. Expect that 
with further loss of daytime heating that showers/storms will end by 
midnight...so will keep the forecast rain free during the overnight 
hours. Infrared satellite imagery shows quite a bit of dense cirrus 
over the central and eastern Gulf approaching the forecast 
area...so skies should remain generally mostly cloudy through the 
remainder of the night. Can/T rule out some patchy fog in the 
normally fog prone areas toward daybreak Monday...especially in 
areas that received rainfall today. That said...given the increase 
in dense cirrus across the area overnight...any fog development 
should remain highly localized. Therefore...will not mention fog 
in the forecast. Low temperatures are expected to bottom out in 
the middle 60s across the Nature Coast...and in the upper 60s to 
lower 70s elsewhere. Update out shortly.

Aviation... 
generally VFR conditions all terminals overnight with some local 
patchy ground fog possible towards morning in normally fog prone 
areas or areas that received rain earlier today. More seabreeze 
convection Monday afternoon.
