(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kjax 170637 afdjax area forecast discussion national weather service jacksonville fl 237 am edt Wed jul 17 2019 Near term through tonight ... the region will be between high pressure to the east southeast and a trough of low pressure to the north northwest through tonight. This pattern will continue a moist south southwest low level flow. The flow in the mid levels is expected to be light and from the west northwest. Storms will develop inland this afternoon, initiated by diurnal heating. Activity which develops will then slowly work toward the east through the afternoon, with a south southeast component to the individual cells due to winds aloft. The slow movement of these storms will lead to locally heavy rainfall. Strong winds from brief downbursts will be possible. The low level flow will help keep the east coast sea breeze pinned near the coast, likely not making it much past i95. Convection is expected to dissipate this evening, with skies clearing overnight. Another hot day forecast today, with temperatures above normal. Heat indices to reach 104-107 this afternoon, just shy of heat advisory criteria of 108. Short term Thursday through Friday night... Mid-level high pressure ridge over the area will start to weaken while drier air aloft advects into NE fl from the atlantic. This should result in slightly better rain chances over SE ga with less coverage over ne fl. Surface ridge to the south will produce a light SW flow with seabreezes moving inland during the afternoons. Slow moving storms may result in areas of heavy rainfall with isolated strong storms possible where cell mergers occur. Temperatures will be at or slightly above average with daytime readings reaching the |
low mid 90s. Long term Saturday through Tuesday... A weakness will develop in the subtropical ridge aloft during the period. Moisture levels will be near average level with inland moving seabreezes. Expect scattered to numerous p.M. Showers and storms each day. Temperatures will be at or slightly above average through the period.

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. |
