5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 240132 afdphi area forecast discussion national weather service mount holly nj 932 pm edt Sat jun 23 2018 Synopsis Low pressure and its associated fronts will affect the area through Sunday. High pressure builds in Monday and Tuesday, then it moves offshore later Tuesday into Wednesday. A warm front moves to our north Wednesday night, then a cold front slowly approaches Thursday into Saturday. Near term until 6 am Sunday morning A warm front is draped roughly from far southeastern new jersey across DELMARVA then west-northwestward into central pennsylvania. This front looks to very slowly migrate northward through the night, however it may not get passed the delaware valley. The low-level flow is rather weak, however an east to northeast component is continuing north of the warm front. This is keeping lots of low clouds in across much of the area with only some improvements across the far southern areas where more of the warm sector has arrived. Even into parts of DELMARVA though some low clouds have expanded southwestward some, and there looked to be an outflow boundary that slid southwestward across southern delaware earlier. Overall, lots of clouds are expected for much of the region through tonight, and with increasing low-level moisture combined with warming above the lingering marine layer, patchy fog is anticipated. Given the cloud over though, widespread dense fog is not expected. Some short wave energy is moving across the area this evening, and there is some semblance of a very weak surface low in northeastern maryland. Given lingering instability across the southern and far western areas, some showers and perhaps a few thunderstorms are anticipated into the overnight. As we get beyond midnight, confidence lowers regarding the shower potential as there does not appear to be much present to provide a focus. As a result, maintained continuity with a dry forecast later tonight. The hourly temperature, dew point, pops, sky cover and wind grids were all updated based on the latest observations and trends. Short term 6 am Sunday morning through 6 pm Sunday A warm front should make it into our far northern areas. A dissipating cold front passes around daybreak, however the main cold front arrives during Sunday afternoon. Temperatures will climb well into the 80s for most. The poconos will likely hold onto the 70s. More sunshine is anticipated Sunday after the day starts with low clouds and perhaps some fog. Chance pops are in place mainly from the i-95 corridor westward, slight chance pops are in place across the coastal plain. The exception is the west northwest zones where a period of likely pops occurs in the afternoon. Farther south and east, the convective potential may not occur until later in the afternoon. The beaches actually may not see any precipitation until the evening. The forecast soundings indicate with ample boundary layer heating, an inverted-v signature develops in the afternoon. This may assist in locally gusty winds with any stronger convective cores. Long term Sunday night through Saturday Sunday night... The last of the showers from Sunday will end from nw to SE during the evening as the cold front upper trough move east of the area. Skies should become partly cloudy overnight and low temperatures will drop into the 60s in most areas. A bit warmer across DELMARVA and perhaps some upper 50s across the southern poconos. Monday thru Wednesday... Three nice days expected with only a small chc for a TSTM across the N W areas Wednesday afternoon. It will be pleasantly mild and comfortable with highs generally in the low mid 80s. These readings are within a few degrees of normal for late june. High pressure will predominate, cresting over the area Tuesday and moving offshore Wednesday. |
Wednesday night thru Saturday... Unsettled conditions along with a change to hot and humid conditions expected. Highs on Thursday may remain in the upper 80s, but 90s are expected Friday and into the upcoming weekend. Plenty of humidity is expected as well. Temperatures and humidity levels will likely fall into excessive heat criteria if things don't change. This will be worth watching over the next few days. A low pressure system and associated fronts will affect the area from Wednesday night thru Friday, we we have some chc pops for tstms in the fcst for those periods. Aviation 02z Sunday through Thursday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Tonight... Ifr MVFR ceilings overall. Some showers around through about 05z, however the thunder chance is rather low. Winds mostly light and variable, and some local fog is possible overnight. Lower confidence regarding the ceiling heights trends and extent of any fog. Sunday... Ifr MVFR to start, then improving toVFR by 15z. Some afternoon showers and thunderstorms are anticipated, especially north and west of phl. Light and variable winds, becoming southwest around 10 knots. Outlook... Sunday night... Sct evening showers then fair withVFR. Monday thru Wednesday...VFR expected. Wed night and Thursday... Sct tstms with restrictions psbl. Marine The conditions are anticipated to be below small craft advisory criteria through Sunday. Winds should hold at 10 knots or less across our northern waters. This will transition into some gusts up to 20 knots for the delaware atlantic coastal waters. A few thunderstorms possible through this evening mainly from about atlantic city southward where locally gusty winds are possible. Because of the warm front, the winds across the far northern waters should stay northeast much of the night. Further south, they should go southerly. For Sunday, southeast to southwest winds 10 knots or less. Seas 3 to 4 feet on the ocean and up to 2 feet across delaware bay. Outlook... sun night... Lingering showers or tstms will end overnight, sub- sca conditions, but higher winds and seas near any tstm. Monday thru Wednesday... Sub-sca conditions with fair weather. Wednesday night thru Thursday... Low end SCA conditions with sct tstms. Rip currents... for Sunday, there is a low risk for the development of dangerous rip currents at the new jersey and delaware beaches due to more of a south to southwest wind.
