Fxus62 kchs 190853 afdchs area forecast discussion national weather service charleston sc 453 am edt Sun may 19 2019 Synopsis High pressure will be the dominant weather feature into next week. Near term through tonight Pre-dawn: another tranquil morning over the forecast area as deep layered ridging prevails. Mainly clear skies with light to calm winds and temps ranging from the mid upper 60s around daybreak, except readings at or above 70 degrees adjacent to the intra-coastal and atlantic waters. Today: ridging aloft is forecast to narrow a bit between mid level short wave energy shifting from the plains toward the great lakes and a weak low just north of the bahamas. The surface ridge axis has slowly lifted a bit north of 30n and this should result in more of a southeast synoptic flow later today. The sea breeze should be even a bit more progressive on it's inland push. Temps will likely be a couple degrees less than on Sunday over the coastal corridor. We maintained a forecast with silent pops over inland zones at mid to late afternoon. Dry air aloft looks substantial, especially in the 850-500mb layers where condensation pressure deficits are higher than on Saturday. While a few spotty showers may pop along the sea breeze (mainly west of i-95) dry and warm weather will continue to persist otherwise. Tonight: the narrow upper ridge will prevail across our entire forecast area while a weak mid level short wave make it's way to north ga late. Skies should remain most clear although some lower stratocumulus could come off the water along the coast late. Low temps similar to past mornings, not much change to the forecast. Short term Monday through Wednesday Monday and Tuesday: the mid upper lvl ridge will temporarily weaken with the approach of a h5 shortwave sfc cold front Monday evening and night. Guidance suggests the front will be in a weakening state, likely stalling before reaching the area, then shifting back north on Tuesday. However, a few showers thunderstorms remain possible over parts of southeast south carolina Monday afternoon evening, then again Tuesday afternoon evening as h5 shortwave energy moves across the area during peak diurnal heating. High temps should peak in the upper 80s to lower 90s away from the coast Monday, then warm into the lower to middle 90s away from the coast Tuesday. Lows should range in the upper 60s to around 70 degrees. Wednesday: sfc high pressure will eventually become centered along the mid-atlantic and southeast coasts while a mid upper lvl ridge of high pressure builds aloft. Given the setup, warm and dry conditions will likely prevail mid week. In general, highs should warm into the low mid 90s well inland while a more direct onshore wind limits highs to the mid upper 80s east of the i-95 corridor. Long term Wednesday night through Saturday

Dry weather should prevail mid to late week as sfc high pressure extending from the western atlantic becomes centered over the southeast under a building ridge of high pressure aloft. A warming trend is anticipated through the week as the ridge aloft becomes quite strong and centered over the southeast united states. Highs should generally range in the low mid 90s away from the coast Wednesday and Thursday with overnight lows in the upper 60s lower 70s. Temps should be even warmer during the weekend as the mid upper lvl ridge makes a slight shift south, setting up a west-northwest downslope flow across the region. This includes warmer conditions along the beaches given the potential for a pinned seabreeze. In general, afternoon highs should peak in the mid upper 90s away from the coast and mid upper 80s along near the beaches. The combination of heat and mixed out moisture could support heat index values around 100 degrees away from the coast Friday afternoon and Saturday afternoon. Overnight lows should also be mild, generally in the low mid 70s each night. Aviation 07z Sunday through Thursday Vfr at kchs ksav through 06z Monday. Extended aviation outlook:VFR conditions are expected at both chs and sav terminals through the middle of the week. Marine A southerly flow will persist through tonight, with near shore backing to more southeast during the afternoon and evening hours along ga coast waters. Prior to daybreak Monday morning, speeds will mainly be 15 kt or less and seas 2-3 ft with 3-4 ft seas over outer ga waters later tonight. Monday through Friday: high pressure will remain the dominant weather feature across the coastal waters through late week, supporting winds seas that remain below small craft advisory levels. In general, south southwest winds will prevail through Tuesday with wind speeds no higher than 15 kts. By Wednesday, winds should become more south southeast, but remain at or below 10-15 kt as sfc high pressure stretches across the western atlantic. Seas will range between 1-3 ft into Tuesday, then build no higher than 1-2 ft Wednesday and Thursday. Tides coastal flooding Shallow coastal flooding is possible with the high tide this evening along parts of the south carolina coast. We continue mention this chance in the hazardous weather outlook. Chs watches warnings advisories Ga... None. Sc... None. Marine... None. Near term... short term... Dpb long term... Dpb aviation... Dpb marine... Dpb tides coastal flooding...

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.
