Fxus62 kgsp 240219 afdgsp area forecast discussion national weather service greenville-spartanburg sc 1019 pm edt Fri aug 23 2019 Synopsis A cold front is expected to slowly sink south across the forecast area tonight into Saturday morning. Showers will persist on Saturday as a wedge of cool high pressure builds into the region behind the front. Fewer showers are expected Sunday into Monday as the high pressure strengthens and persists. Showers and thunderstorms return for Tuesday and Wednesday as temperatures rebound ahead of the next cold front. Drier weather is possible behind the front to end the work week. Near term through Saturday As of 1000 pm edt Friday: mainly another round of updates to pops to lower them some more during the early overnight, but to raise them again across the NW piedmont later in the overnight hours with cams bringing more showers into the region with the wedge front. Other grids still looking good for now. Otherwise, expect the strong convection to diminish but shower activity will likely linger as confluent flow upstream of a trough over the great lakes drives a sfc high in our direction. This keeps the pushing the cold front south in "backdoor" fashion. Low-level flow will veer to easterly by early Saturday. The combination will provide added lift, so pops remain fairly high chance throughout the night. Stratus will settle in across the area as well. Lows will be above normal. Cold air damming settles in across the area Saturday as the high wedges in from the northeast and the front stalls just to our south. Copious low level moisture and easterly flow will keep low clouds across the area through the day. Showers will be numerous as well with thunderstorms limited to the mountains and the area along and south of i-85. The severe threat diminishes as instability is weak and dcape lacking. Highs will be well below normal with most areas below 80 degrees. The exception will be the upper savannah river valley where mid 80s linger. Short term Saturday night through Monday As of 245pm edt Friday: with increasing confidence in the passage of the wedge front earlier on Saturday, Sunday looks to be solidly cool and cloudy with periods of light rain and drizzle across the area, as high pressure funnels anomalously cool and stable air into the region. Models have oscillated on the strength and exact orientation of the low-level fetch of moist atlantic air above the wedge for Sunday and Monday, with the overnight guidance weaker and the latest 12z guidance stronger with the 900-850mb flow out of the ene. Nevertheless, low-level convergence and weak isentropic lift will persist at least into Monday morning which will maintain periods of light rain and drizzle, especially across the favorable eastward facing slopes along the blue ridge escarpment and the adjacent foothills. Confidence is increasing that the wedge of high pressure, centered near maine, will be reinforced Sunday night into Monday morning by the developing area of low pressure near S fl, as guidance continues to lift the low north along the atlantic coast. Counterclockwise flow around the low as it parallels the north carolina coast on Monday would strengthen northeasterly flow within the wedge while weak subsidence associated with the periphery of the low is forecasted to reduce pops east of the blue ridge and foothills during the day Monday. Aloft, the region is on the southern edge of an evolving omega block, which begins to break down later Monday in response to height falls over the ohio valley ahead of our next system. Max temps will bottom out 8-10 degrees below normal on Sunday and will rebound somewhat on Monday (though still 3-6 degrees below normal) with the shortwave ridge aloft and the resultant loss of

cold air advection within the wedge. Long term Monday night through Friday As of 245pm edt Friday: overall the forecast has changed little for the middle and end of the work week next week, with the next system approaching from the west on Tuesday and frontal passage expected sometime on Wednesday. The high pressure wedge will breakdown overnight Monday in response to height falls aloft and the coastal departure of an area of low pressure. Modest elevated instability (<500 j kg sbcape; 1000-1500 j kg mucape) returns for Tuesday across the mountains with some drying of the column and slightly more favorable lapse rates associated with a weak shortwave trough. However, there will be plenty of details to sort out in the days ahead because the stabilizing influence of the coastal low may continue to counter the weak trough, especially across the eastern counties, where current forecasted profiles remain stable. Therefore, the current call for isolated to scattered showers and thunderstorms on Tuesday will likely be refined as confidence evolves. Nevertheless, a weak cold front is progged to move through the forecast area on Wednesday, with decent model agreement on timing and shower and thunderstorm coverage, which again, is not terribly impressive. There remains disagreement between the gfs and the ECMWF on precip chances for Thursday afternoon behind the front with the GFS remaining unsettled despite agreement that the front will stall along the atlantic coast. This is the opposite of the overnight solutions. For now, the forecast trends drier on Thursday. Complications continue into Friday as the guidance tries to develop low pressure along the stalled coastal front. Easterly flow and an in situ wedge may return to end the work week, but there will be plenty of time for this to change. Southerly (return) flow will be slow to return on Tuesday but with no connection to cooler air and greater insolation, temperatures are expected to recover a bit more with highs just 2-4 degrees below normal. Near-normal to slightly above-normal temperatures return by Wednesday in advance of the approaching cold front. Aviation 02z Saturday through Wednesday At kclt and elsewhere: still some convection impacting kclt and have continued tempo tsra there through 01z, but should be moving out with mostly vcsh shra thereafter, though cannot completely rule out isolated -tsra. As we move into tonight, cad will begin to develop, with MVFR to ifr CIGS pushing in from NE to SW overnight, and expect restrictions to remain during the day tomorrow. Guidance keeps kclt khky ifr all day, other sites have at least some improvement to MVFR. Confidence low on coverage of any tsra that might develop due to the stabilizing nature of the cad, so continued mention of prob30 tsra for kand only, with vcsh or shra elsewhere. SW winds at taf time for all but kavl will veer around to NE as the damming builds in, with some low-end gusts possible especially Saturday afternoon. Outlook: cold air damming will keep lower CIGS in the area through Sunday. Drier air moves in for Monday, but moisture and another frontal system move back in by midweek with associated restrictions possible again.

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.
