(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktae 211907 afdtae area forecast discussion national weather service tallahassee fl 307 pm edt Sat apr 21 2018 Near term [through tonight] Low-level easterly flow will continue across the region overnight under the influence of strong surface high pressure parked over the mid-atlantic and new england. Upper low currently over the high plains will gradually shift westward into arkansas overnight. Onshore flow above the boundary layer will increase across the local area as a result, providing enough lift for scattered showers to develop after midnight. Rainfall amounts should be light with this activity. Expect low temperatures in the lower to mid 60s overnight. Short term [Sunday through Monday night] Quiet weather will come to an end on Sunday as an upper level low and associated surface front move into the region. At the beginning of the period, showers and thunderstorms will be ongoing across eastern portions of the lower mississippi valley and southeast. This activity will move into the tri-state region late Sunday afternoon early Sunday evening and is expected to persist through Monday morning before conditions gradually improve from west to east. The main threat from this system will be heavy rainfall, with forecast rainfall totals of 2 to 4 inches generally west of the apalachicola chattahoochee rivers and 1 to 2 inches east. Though heavy rain will be the main threat, deep layer shear on the order of 40+ knots and CAPE in the range of 500 to 1000 j kg will yield an environment capable of supporting isolated strong to severe thunderstorms, particularly on Sunday evening. It is noteworthy that low level directional shear looks fairly substantial in the current model guidance, and storm mode will likely consist of broken cell clusters semi-discreet cells. An isolated tornado is not out of the question in this kind of environment. Isolated instances of damaging wind gusts are possible, especially with any cell to cell, cell to cluster mergers that may occur. Seasonal temperatures will persist through the period. Long term [Tuesday through Saturday] The upper low that will be responsible for Sunday and Monday's showers and thunderstorms will slowly lift poleward on Tuesday before getting kicked eastward by an approaching clipper system from the west Tuesday night Wednesday morning. Model guidance remains consistent this afternoon in depicting some wrap around moisture yielding showers across southeast alabama southern georgia on Tuesday. Quiet weather will be short-lived on Wednesday, as a quick moving shortwave trough will bring another chance of showers to the region late Wednesday early Thursday time-frame. After this system, model guidance diverges significantly moving into the weekend, thus pops for Friday and Saturday are low confidence at this point. Temperatures will remain seasonal through the period. Aviation [through 18z Sunday] Easterly winds will continue through the overnight hours into early Sunday, with ifr CIGS possible after midnight at all terminals. Showers will be possible for the florida and alabama terminals overnight. However, heaviest rainfall will be beyond the current forecast period. |
Marine Elevated easterly winds will continue to yield advisory level conditions across coastal waters through Sunday afternoon. A small craft advisory remains in effect until Sunday afternoon. Showers and thunderstorms are likely Sunday through Monday as a cold front approaches. Fire weather While winds will be elevated over the next few days, rh values will preclude red flag warnings. Widespread showers and thunderstorms are expected Sunday into Monday. Hydrology All river points are below action stage this afternoon. Rainfall totals of 2 to 4 inches can be expected west of the apalachicola chatahoochee rivers Sunday through Monday, with general amounts of 1 to 2 inches east. Rainfall will be heavy at times, likely causing minor flooding issues in urban and poor drainage areas. Instances of flash flooding cannot be ruled out at this time, given the rainfall rates that will be possible with some of this activity.

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. |
