(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 krlx 231039 afdrlx area forecast discussion national weather service charleston wv 639 am edt Fri aug 23 2019 Synopsis Cold front finally exits to the south today. High pressure with dry, cooler weather for the weekend. Near term through tonight As of 625 am Friday... showers widespread this morning, should dry out north to south later today in a gradual manner. Some minor pop adjustments, but the formation of the showers has continued to follow that low level frontogenesis. As of 235 am Friday... in the midst of strengthening lower level 900-800mb frontogenesis, so expect the coverage of showers to increase through sunrise this morning. A weak wave of surface low pressure is keeping the forward motion of the cold front to a minimum but should see the front clear our portion of the mountains after 15z. The pops continue in the wake of the front, however, due to a 500mb axis embedded in the very broad cyclonic flow over the great lakes. Much drier air at the surface, lower, and mid levels moves in with this wholesale airmass change once the wave aloft passes and high pressure builds over the great lakes. Lower dewpoints tonight allow for lows to drop back into a more comfortable range after a few days of heat across the region. Short term Saturday through Monday As of 313 am Friday... mainly dry conditions are expected on Saturday due to the influence of an expansive surface high centered in quebec. However, can't completely rule out a few isolated showers storms Saturday afternoon in extreme southeastern zones where better quality moisture and instability is expected (dewpoints in the low mid 60s and cape around 1,000 j kg). The greatest chance of any precipitation will be in southwest va where low chance pops are in place. Elsewhere, the atmosphere will be very dry with surface dewpoints in the mid upper 50s, yielding pwats between a half inch to an inch. With high temperatures forecast to reach the upper 70s low 80s, fantastic weather is expected with comfortable humidity levels. As the aforementioned high pressure shifts east towards the canadian maritimes on Sunday, return flow will give temperatures a boost of a few degrees. This should translate to highs in the low 80s across the lowlands on Sunday afternoon, just a degree or two below normal for this time of the year. Upper ridge axis across the great lakes should provide for a mainly dry forecast once again, but some low pops are included across southern areas as a cut-off low rotates east of the area in the mid-atlantic region. Regardless, with little to no instability expected and subsidence in place, most of the region should be dry. By Monday, upper ridge axis continues to push to the east and a shortwave trough will move across the midwest. This leading shortwave trough will eventually become absorbed by a larger scale trough emerging from the northern plains late in the short term period. However, the leading shortwave trough may get close enough to our region on Monday afternoon to bring an increase in pops from west to east through the day, as the GFS suggests. The ecmwf, however, is slower with the arrival of the leading trough and thus, holds off on most of the precip towards mainly the long term period. For now, went with a consenus blend of models which does support slight chance pops across the region Monday afternoon into the evening. Long term Monday night through Thursday |
As of 313 am Friday... by Monday night, the aforementioned main trough axis will extend from the canadian prairies southeastward into the ohio valley, pushing a cold front through our region on Tuesday. This will bring widespread showers and thunderstorms throughout the area on Tuesday. With models projecting pwats around 1.50-1.75 inches, heavy downpours will be possible. There also will be some modest shear, with models at this distance suggesting around 30 kts in the 0-6 km layer. However, instability will be in question given the abundant cloud cover that is expected. Precipitation will end from west to east throughout the day on Wednesday, with high pressure building in across the ohio valley. This feature should then be in control through the remainder of the week, keeping conditions mainly dry and seasonal through the end of the long term period. Aviation 10z Friday through Tuesday As of 620 am Friday... widespread showers with isolated thunder this morning should become less numerous from north to south as Friday progresses in time. Until then, bouncing observations can be expected in and out of showers. Ceilings and visibilities have been variable since the last synoptic issuance of the tafs a few hours ago and this is expected to continue for a few more hours. Vfr later in the day for all sites. Fog potential to form in the valleys is on the higher side tonight after 04z. Forecast confidence and alternate scenarios through 12z Saturday... forecast confidence: medium. Alternate scenarios: more brief ifr is possible in heavy showers. Isolated thunder could creep in to the mix. 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. |
