Area Discussion for - Philadelphia/Mount Holly, PA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 201428 afdphi area forecast discussion national weather service mount holly nj 928 am est Wed feb 20 2019 Synopsis A complex area of low pressure and frontal system will move north through the eastern united states bringing the area a mix of wintry precipitation today into tonight. High pressure will build into the area for Thursday and Friday. Strong low pressure moving across the great lakes should bring mostly rain to the region for much of Saturday and Sunday. High pressure is forecast to return early next week. Near term through tonight 930 am: made some changes to the temperature and weather type forecast to account for current trends. Boundary layer is getting closer to saturation, so a few sites have begun to report snow reaching the ground, including in chester county, philadelphia, and portions of delmarva. This trend is expected to continue through mid day, as snow spreads over the region. After 18z, expect the warm air aloft to advect in, resulting in first sleet mixing in (initially the warm layer looks to be elevated enough to support more sleet than freezing rain), then a mixture of sleet and freezing rain. This remains the trickiest part of the forecast since any slight change in the temperatures will mean the difference between sleet freezing rain or rain. With the morning update adjusted temperatures closer to the lamp and a blend of short range models which appear to be handling the surface temperature trends the best so far. As a result, made some minor changes to the weather timing of transitions to match the current temperature forecast. The transition should be well under way across DELMARVA by early this afternoon. For much of the i95 corridor, the transition is expected to occur mid afternoon to early evening (unfortunately not likely to see a change over to all rain in these locations before the start of the evening commute). The southern poconos and NW nj will be the last to see the change over to all rain, which may not come until well after midnight tonight. Snow and ice amounts: with this update, made only minor adjustments to the snow amounts (primarily given the slightly later start than previously expected). No changes to the ice amounts with this update. Still looking at a general 2 to 4 inches of snow and sleet over most of eastern pa, central and northern nj and northern parts of the delmarva. Areas south of here will see amounts mostly in the 1 to 3 inch range. Additional concern is freezing rain. A light glaze up to a few hundredths of an inch of ice accretion is likely over the northern DELMARVA N E along the i-95 corridor while upwards of one to two tenths of an inch of ice is expected over portions of eastern pa from western chester county north through berks county, the lehigh valley into the southern poconos. Impacts: regardless of the exact snow and ice amounts, we remain very concerned that much of the region could be seeing the greatest impacts coincident with the evening commute. The one exception is much of the DELMARVA and SE nj which should see the change over to all rain before this time. Even if the snow and ice amounts are lower, the potential for ice on top of snow, could result in very slippery conditions. Short term Thursday Quieter weather on tap for Thursday. The last of any precip (which will be in the form of rain showers) will come to an end in the early morning as a weak cold front behind the low clears the delmarva. Otherwise expect developing sunshine, breezy, and mild conditions as low pressure moves into the canadian maritimes and high pressure moves into the midwest. Highs will range from the mid 40s over the southern poconos to the low to mid 50s for areas near and S E of the i-95 corridor. Long term Thursday night through Tuesday 4 am update... Overall, no major changes to the long range forecast. Quiet weather looks to persist through Friday before the next system, mainly a rainstorm, affects the area over the weekend. Do have some concerns that there could be some strong winds on the back side of this system for late Sunday so we increased the winds for this time period. Previous discussion: mid- upper-level ridge is forecast to build over the eastern u.S., while another shortwave trof begins to eject out of the southwest. Winds aloft become southwest and begin to bring increasing cloud and moisture into the mid- atlantic. Light precip is forecast to develop and spread northeast into the area on Saturday, or possibly late Friday night in delmarva. Confidence in the time of arrival is relatively low, and any rain amounts on Saturday should be light. Temps should be warm enough to avoid any sig snow or ice with this event. Saturday night looks more favorable for significant rain as uvv and warm advctn increase ahead of the upper trof and deepening sfc low, both moving northeast into the great lakes. A warm front is forecast to move north through the area early Sunday resulting in mild temps and more showery precip in the sfc low warm sector during the day. A cold front passage late in the day should end the precip. High pressure is expected to build into the area early next week, bringing fair wx an a return to near normal temps for late feb. Aviation 14z Wednesday through Sunday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, |
kmiv, kacy and surrounding areas. Wednesday... Ifr snow will spread sw-ne through the terminals between 14-17z. A transition to sleet freezing rain is likely at all terminals around 20-22z, with all terminals outside of kabe krdg transitioning to rain by around 00z (although ifr ceilings will persist). Generally east-southeast winds below 10 knots. Moderate confidence in precipitation type timings. Wednesday night... Lingering freezing rain at kabe krdg likely transitions to rain around 03-06z, all other terminals will see rain with ifr ceilings. Rain tapers off w-e after about 06z, although ifr-MVFR ceilings and potentially lowered visibilities in mist likely persist after rain ends. Winds generally light with llws possible after 06z. Moderate confidence outlook... Thursday... MVFR or lower conditions are possible in the morning, improving toVFR by the afternoon. Winds becoming W nw between 10-15 knots with some gustiness. High confidence. Friday...VFR conditions with northwesterly winds under 10 knots. High confidence. Saturday... GenerallyVFR conditions early but possibly lowering to MVFR in the afternoon. Light southeast winds. Saturday night... Widespread MVFR ifr conditions expected in rain and fog. Variable winds mostly less than 10 kt. Moderate confidence. Sunday... Conditions should improve toVFR MVFR but lower at times in showers. South winds becoming gusty and shifting to west late in the day. Low confidence on timing. Marine Winds seas increase today with SCA conditions likely by this afternoon and continuing tonight over the coastal waters. Also expect some visibility reductions in snow, sleet, and rain today into tonight. Outlook... Thursday... Marginal SCA conditions possible as seas hover near 5 feet and west winds gusts to around 20 knots. Friday Saturday... Seas winds dipping below SCA by early Friday morning with sub-sca conditions prevailing through Saturday. Sunday... SCA conditions possible in gusty SW winds and building seas. Tides coastal flooding Northeast flow turns east to southeast and increases today as low pressure approaches from the south and west. The higher of the two high tide cycles will occur this morning, when departures should be around 1 2 foot above normal. Minor coastal flooding thresholds may be touched in some spots this morning, but not anticipating widespread minor coastal flooding advisory. Although locally minor coastal flooding cannot be ruled out, do not think it will be widespread enough to warrant a coastal flood advisory. Elevated tides may continue into Thursday morning.

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. |
