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. |

Synopsis for the tidal potomac and md portion of the chesapeake bay.. High pressure will move offshore through tonight. A warm front will approach the waters late tonight before passing through Thursday and a cold front will pass through the waters Thursday night. The cold front will stall out nearby for the rest of the weekend into early next week. A small craft advisory will be needed for the waters Friday, and possibly into Friday night.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 222020 afdakq area forecast discussion national weather service wakefield va 420 pm edt Wed may 22 2019 Synopsis High pressure settles offshore into tonight. This area of high pressure then shifts well off the southeast coast Thursday into Thursday night as low pressure passes north of the region. Near term until 6 am Thursday morning As of 330 pm edt Wednesday... winds will become sse though this evening, as sfc high over the region nudges offshore, and remains near the coast through early Thursday. Becoming mostly clear with an increase in mid and high clouds western sections late. Small chance of some very light rain sprinkles over the i-85 corridor towards morning in association with some very shallow overrunning moisture. Chances of measuring pcpn are very low over this area through 12z, so have pulled out rain chances and just showed increasing clouds in grids. One more cool, comfortable night... As temperatures fall quickly (especially coastal sections) then stabilize overnight, with early morning low temperatures to range from the mid 50s over the interior ERN shore and interior SE va NE nc, to the upper 50s around 60f elsewhere. Short term 6 am Thursday morning through Saturday night As of 330 pm edt Wednesday... the mid upper level ridge axis will push offshore Thursday morning as a shortwave trough tracks through ERN great lakes. Meanwhile, the low-level flow will become sw, which will allow for slow moistening of the low-level airmass. Warmer high temperatures in the mid 80s to around 90f are expected across our area, with low 80s for much of the ERN shore and coastal se va NE nc, and upper 70s at the immediate atlantic coast of the ern shore. We are continuing to monitor the potential for some thunderstorms thu aftn and evening. SPC has added a small area of slight risk over the far northern quarter of the area (ric to sby and north). Convective threat for Thursday remains conditional; and is dependent upon the development of an MCS upstream from kstl to ksdf late tonight early thu. Should this feature develop as modeled by cams, the MCS would push across from WV pa into S pa and nj Thursday aftn and evening. This is expected to trigger convection N of the region in a zone of 40-50kt 500mb flow and 35-45kt 700mb flow. Must note that this shortwave will dampen upper ridging to a degree... With resultant quasi-downslope flow serving to lower areal coverage of tstms over the local area. That said, there is the potential for isolated to widely sct outflow- driven tstms from this feature, which could move off the higher terrain into the NW piedmont after 20z 4pm later Thursday aftn, and potentially pushing across the NRN neck and md ERN shore by mid to late Thursday evening. Obviously, a lot has to go "right" for this convection to develop as modeled, and for that reason... We will continue to cap pops at 30%-40% for now, highest in the slight risk area from the NW piedmont counties to the md ERN shore, bordered by 20% for much of the area, and less than 15% far SRN va NE nc. The potential for some stronger storms does exist, given cooling drying aloft... With large hail and damaging winds the primary threats in any convection that can make its way toward the area tomorrow evening. Heat then builds for Friday through the weekend. Good model agreement continues with respect to building strong upper ridge back to the north Fri sat, before the ridge flattens late in the holiday weekend courtesy of northern stream shortwave sliding across the upper great lakes and SE canada. Increasingly hot, though remaining mainly dry. Some isolated (mainly diurnally driven) convection possible along lee troughing to the west Sun afternoon. Highs in the mid 80s to near 90 on sat, 80s along the coast, l-m 90s inland on Sunday. Early morning lows 60s to near 70. Long term Sunday through Wednesday As of 250 pm edt Wednesday... summerlike temperatures remaining above normal through the extended forecast period. An upper level anticyclone remains centered along the gulf coast early next week, putting our region in w-nw flow aloft. Meanwhile... An anomalous deep trough aloft will continue to largely remain out over the WRN conus. Weak frontal boundary crosses |
the area Sun evening-sun night, but only isolated tstms are expected attm (mainly N ne). Isolated-scattered aftn evening tstms are possible on mon, but the chance of this is only ~20%. Drying out from tue-wed as upper ridging amplifies over the us east coast as the aforementioned deep trough aloft ejects out into the NRN plains. Lows Sun night in the u60s-around 70f. Highs Mon in the 80s over the lower ERN shore to the low 90s inland. Highs Tue from the low 80s over the ERN shore to near 90f inland. Forecast highs on Wed are in the low 90s in most areas, but there is the potential for it to be even warmer. Aviation 20z Wednesday through Monday As of 145 pm edt Wednesday... high pressure centered N of the region will slide offshore through this evening. Light nne winds become sse 5-10kt at ric sby by late this aftn, and ese 5-10kt and phf orf ecg under a mostly sunny sky (sct-bkn high clouds over eastern shore around ksby terminal). By tonight, a light SE wind will become sw under a mostly clear sky. Outlook: there is a 20-30% chc of showers tstms (primarily ric- sby and points n) after 20z 4pm later Thursday aftn evening as a trough slides across the region in NW flow aloft. Mainly dry conditions are expected Friday through the weekend as weak high pressure prevails over the region. Marine As of 345 pm edt Wednesday... high pressure will move off shore tonight. Winds overnight will be 5-10 kt and seas will come down to around 1 ft in the bay and 2-3 ft in the atlantic. As a cold front approaches from the north, southwesterly winds will increase tomorrow afternoon. Not going with any SCA for tomorrow afternoon because conditions will be marginal. Gust may exceed 25 kt for a short period of time and waves will touch 5 ft off the eastern shore's atlantic coast(mostly far offshore edge of our zones). Farther south in the atlantic, winds will between 15-20 kt with waves 3-4 ft. In the chesepeake bay and rivers, winds Thursday afternoon will be 10-15 kt and waves will be around 1-2 ft. Behind the cold front on Friday, high pressure will build back into the area for the holiday weekend. Looks like winds and seas will stay below SCA criteria through Monday.

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. |
