10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 krlx 211843 afdrlx area forecast discussion national weather service charleston wv 243 pm edt Tue may 21 2019 Synopsis High pressure continues into tonight. Much warmer Wednesday into the weekend with chances for showers and thunderstorms somewhere in the area each day. Near term through Wednesday As of 130 pm Tuesday... an upper level ridge axis will work its way into the forecast area from west to east through the night. These rising heights will keep precipitation at bay... However we do have a fair amount of clouds across the forecast are as cirrus aloft and some diurnal cumulus below that. These clouds have really tempered temperatures so far today, but visible satellite shows increasing sunshine is working in from the west, so did not significantly cut back temperatures for the remainder of the afternoon. Surface high pressure slides to the east overnight, which will turn winds around to southerly by morning. Have slightly non- diurnal trend for hill tops across the south through the pre- dawn. This will also bring a significantly warmer day on Wednesday. The upper ridge axis starts heading east by late afternoon which may allow a shower or storm to drift into the far northern CWA by late afternoon evening. Short term Wednesday night through Thursday night As of 235 pm Tuesday... for Wednesday, broad high pressure will sit just south of the area which will help yield and weaken a frontal boundary trying to slide into the area from the west. Still a chance for some light showers, however it looks like most of the energy will be suppressed from the ridging and drying of mid levels. With the elevated instability that models hint at, there is still a threat for thunderstorm activity which will mostly be diurnally driven. Since instability will be relatively weak, not expecting anything severe at this time. Once the boundary moves past the area another more organized frontal boundary moves closer on Thursday and a wave of energy traverses around the clockwise flow of the ridge and impacts our area. The precipitation shield ahead of the cold front associated with a surface low over the great lakes will overspread the area along with the aforementioned disturbance. Rain showers and thunderstorms will be an issue in the afternoon with a frontal boundary associated with the low providing plenty of lift and moisture. Along with high instability (ml cape 3000+ j kg) and shear over 40kt, storms are capable of producing severe hail and damaging wind. SPC has our northern half of the area in a marginal to slight risk for severe. Most of the energy will ride along this clockwise path and exit overnight. Long term Friday through Tuesday As of 235 pm Tuesday... Friday should be a relatively quiet weather day with high pressure ridging and lack of any real ascent, however a diurnally driven shower or storm cannot be ruled out with modest instability expected. On Saturday, another system with a frontal boundary will |
affect the area and provide ample moisture and instability for more potential thunderstorms. High pressure shifts slightly south allowing multiple waves to rotate around to the area through Sunday for more unsettled weather. Models indicate a frontal boundary and associated surface low pressure system to the west will hang around until the beginning of the new week (mon-tues). On the other hand, models battle each other with trying to build in high pressure sooner, while the upper low loses focus and strength. Thus, confidence of timing and strength of this system is low. There is a hint of another system around the middle of next week. At any rate, with models being in such disagreement there is very low confidence on timing of these systems. Continuing heat with temperatures in the upper 80's along with plenty of moisture and chances for thunderstorms will be the moral of this long term forecast. Aviation 19z Tuesday through Sunday As of 130 pm Tuesday... have a mix of cirrus and diurnal cumulus across the forecast area, varying from few to broken as patches drift through. Did include a period of MVFR in ckb and crw where the cumulus is most widespread. OtherwiseVFR expected through the TAF period. North to northeast winds will become southerly late tonight into tomorrow as surface high pressure drifts to the east. Forecast confidence and alternate scenarios through 18z Wednesday... forecast confidence: high. Alternate scenarios: timing of MVFR ceilings today may vary. Experimental table of flight category objectively shows consistency of WFO forecast to available model information: h = high: TAF consistent with all models or all but one model. M = medium: TAF has varying level of consistency with models. L = low: TAF inconsistent with all models or all but one model.

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. |
