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 kphi 171423 afdphi area forecast discussion national weather service mount holly nj 923 am est Sat nov 17 2018 Synopsis High pressure over the great lakes and ohio valley builds east today, passes overhead tonight, then moves out to sea Sunday and Sunday night. Several upper level disturbances will pass north of the region Monday and Monday night, and then a cold front passes through Wednesday night. High pressure builds to the north to close out the week. Near term until 6 pm this evening 9 am update: no major changes with this update. Stratocumulus persists northwest of the fall line, but across the coastal plains, it has eroded for the most part. Still, given the strong cold air advection, heating should be limited even if the clouds erode more. Previous discussion... a strong vort MAX is moving offshore new england early this morning, leaving the northern mid-atlantic in quasi-zonal midlevel flow. A surface high to our south and west will provide for westerly surface flow today. Fairly strong cold advection in the low levels will continue today, so not expecting too much of a warmup from yesterday. Statistical guidance has temperatures about 2-6 degrees warmer than yesterday, in general. I leaned toward the cooler guidance somewhat, mainly because I am somewhat concerned it will be a little cloudier than the model consensus suggests. The strength of the cold advection near the surface is clearly allowing for the development trapping of upstream stratocumulus, with models poorly forecasting the southeastward expansion and oscillation of the cloud deck. I expect this to continue to be the case today. In addition, a dry weak cold front will be approaching from the west, and this may be enough to curb stronger heating, especially in the north west. Cannot rule out a flurry or even a rain snow shower in the northern CWA today, but model guidance is generally excluding this as a risk. Given the nearly universal consensus on this, considered this too low of a risk for inclusion in the forecast at this time. Short term 6 pm this evening through 6 am Sunday The surface high to our west will build into the northeast tonight, allowing the weak cold front to move through the region during the period. Surface flow will become more northerly, though it may decouple entirely as the surface ridge approaches. Meanwhile, midlevel zonal flow will continue, and a weak vort max passage during the evening will likely keep some amount of cloudiness around, especially to areas north and west of the urban corridor. Cannot completely rule out a flurry shower in the poconos and vicinity this evening, though the threat looks too low for forecast mention at this time. Otherwise, the CWA is expected to be dry. Given the infiltration of the surface high to our north and west upstream of the weakening cold front passing through, minimum temperatures will likely be somewhat lower than those observed this morning, though the potential for considerable cloudiness may impede this cooling somewhat. In general, followed a consensus statistical blend. Long term Sunday through Friday High pressure over the area Sunday morning moves out to sea during the day. The first of several weak clipper systems will approach in the afternoon, and passes north of the area late Sunday and Sunday night. Thermal profiles have temperatures below freezing in the southern poconos and far northern new jersey, where precip should fall as snow. Temperatures will generally above freezing from around i-78 to i-80, where precip will start out as rain, then temps fall through the night, allowing for rain to mix with some snow. QPF totals will be less than 1 10", with the bulk of |
the QPF in carbon and monroe counties, so not expecting much in the way of snowfall. Will cap pops at chance, mainly for the northern half of the forecast area. The second clipper system will pass through the region Monday afternoon and Monday night. Again, temperatures will be cold enough for all snow along and north of around i-78, and rain south of that. QPF amounts will once again be light, generally less than 2 10" inch, with the highest amounts in the southern poconos. Accumulating snow possible, especially in the higher elevations. Surface high pressure passes through the region on Wednesday, and then a cold front will pass through the region Wednesday night and thanksgiving morning. An arctic airmass builds into the region for the end of the week, as 850 mb temps will fall to -12c in DELMARVA to -20c in the southern poconos. High pressure builds east on Friday, and the airmass warms back up a bit, as 850 mb temps warm back to 0 to +3c. Aviation 14z Saturday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Today... MainlyVFR, though transient MVFR may occur at rdg abe this morning. Bkn-ovc CIGS around 3000-5000 feet early this morning may scatter out at times, especially from the philly terminals southeastward, but a more considerable cloud deck most of the day cannot be ruled out. Winds generally westerly around 10 kts. Moderate confidence. Tonight... MainlyVFR, though some MVFR conditions may occur from time to time, generally northwest of phl. Winds becoming light variable. Moderate confidence. Outlook... Sunday-Tuesday... Periods of MVFR conditions possible with a chance of showers. Snow possible at krdg abe at night. Tuesday night-Wednesday...VFR conditions expected. Marine Winds have dropped below 25 kt, thus the SCA was allowed to expire. West to northwest winds should diminish to 10 to 20 kts by this afternoon with seas lowering to 3 to 4 feet. Sub- advisory conditions should continue tonight, with directions becoming more northerly with time as a weak cold front moves through the area. No precipitation is expected through the period. Outlook... Sunday through Tuesday... Conditions expected to remain below advisory levels with west-northwest winds 10-15 knots. Tuesday night... Conditions may increase to near small craft advisory levels. Wednesday... Conditions expected to be below advisory levels. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md...

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. |
