(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 220149 afdphi area forecast discussion national weather service mount holly nj 949 pm edt Tue aug 21 2018 Synopsis A warm front is forecast to lift through our region this evening and overnight. A cold front approaching from the west is expected to move slowly across eastern pennsylvania, northeastern maryland, delaware and new jersey on Wednesday. High pressure is anticipated to follow for Thursday and Friday. The main center of the high should move out to sea over the weekend but it is expected to continue influencing our weather into early next week. Near term until 6 am Wednesday morning Warm front currently extends across central pennsylvania southeastward into delaware and southern new jersey accompanied by cluster of heavy showers and thunderstorms. This front connects back to a surface low moving NE across eastern canada. As we head through tonight, have concerns once again for heavy rainfall with an associated flash flood threat. The main concern right now is across eastern pennsylvania where 1-hour flash flood guidance is around 0.50 inches or less. Heavy rain is falling from these storms and can easily produce upwards of 2-3 inch per hour rates. Thinder chances will continue through the next few hours but the best instability is already waning and lapse rates are weak across our region. Have reduced the thunder threat through the overnight hours to a slight chance, removing any mention of thunder by daybreak. Showers storms will move out through the predawn hours as the low tracks into quebec with the cold front right on our doorstep by morning. It will be a mild, muggy night in the warm sector with lows generally in the upper 60s to low 70s. Short term 6 am Wednesday morning through 6 pm Wednesday Low pressure will move northeast across quebec through the day with its attendant cold front slowly moving south east across the forecast area through the day. Also, the upper level trough will be continuing to linger over the NE CONUS in the system's wake. As a result, expect considerable cloud cover to persist across the area with some scattered showers and storms possible. Highs will generally be in the low to mid 80s except 70s across the southern poconos. The main change through the day though will be falling dew points as the front moves across. It will start out quite muggy but by late day expect dew points in the low to mid 60s... Much more comfortable in comparison! Long term Wednesday night through Tuesday A long wave mid level trough is forecast to be located over eastern canada and the northeastern states on Wednesday night and Thursday before it lifts northeastward and away from our region. The mid level pattern is expected to flatten a bit over the weekend before some ridging begins over the eastern states early in the new week. Surface high pressure is anticipated to be centered in the middle mississippi river valley on Wednesday night. The high will build eastward with its center forecast to pass through our region on Friday before moving out to sea. Dry weather is expected for Thursday and Friday with noticeably lower humidity than we've been experiencing. Dew point readings should drop into the 50s. The surface high is expected to get absorbed into the large high over the western north atlantic. The surface flow should begin to favor the south and southwest resulting in an increase in heat and humidity during the period from Saturday through Tuesday. The anticipated rise in humidity levels may bring about isolated showers and thunderstorms on Monday and Tuesday mainly during the afternoon and early evening hours. |
Daytime highs should favor the upper 70s and lower 80s on Thursday and Friday, the 80s on Saturday and Sunday, and the upper 80s and lower 90s on Monday and Tuesday. Overnight lows should also increase gradually during the period, starting in the 50s and 60s on Wednesday night and ending in the upper 60s and lower 70s on Monday night.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
