(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 170750 afdtbw area forecast discussion national weather service tampa bay ruskin fl 350 am edt Wed jul 17 2019 Discussion (today - Tuesday) Strong mid to upper-level ridge over florida will build northward over the next several days and extend across much of the eastern 2 3rds of the country by the weekend. This will bring hot and humid conditions to most of the eastern u.S. Models are in fairly good agreement depicting a deepening mid to upper-level trough over the eastern half of the nation on Monday and Tuesday, displacing the ridge to the south and east. Closer to home, our weather will be dependent on the position of the sub-tropical ridge. Our afternoon storms are more numerous near the coast south of the ridge axis, and farther inland north of the ridge axis. Since the low-level ridge axis is forecast to meander over central florida through the weekend, expect the best coverage of afternoon storms to be near the coast south of tampa bay, and farther inland to the north. As the upper-level ridge moves out in response to the deepening trough on Monday and Tuesday, the surface ridge is likely to retreat into the atlantic as well, allowing sea breezes to push more quickly inland both days. This should keep highest rain chances east of i-75 for the start of next week. Aviation Similar to yesterday, scattered to numerous showers and storms |
will develop along afternoon sea breeze boundaries again. Expect predominantlyVFR conditions with a good chance of some intermittent MVFR ifr lifr conditions after 18z.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
