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 261358 afdphi area forecast discussion national weather service mount holly nj 958 am edt Sun may 26 2019 Synopsis A warm front will continue to move away from the area this morning. A cold front attached to low pressure across canada will move through the region later today. High pressure will settle across the area Monday then another disturbance will be across the area Tuesday. An unsettled pattern is expected for the middle and end of the upcoming week. Near term until 6 pm this evening For the 930 am update: made some changes to pops based on current satellite and radar trends. A line of storms continues to progress east ahead of the cold front in eastern oh western pa. Further, we are seeing convection initiate over western md northern wv. This second area of convection may be orographically enhanced. None the less, high resolution models are not depicting the morning convection well. Closer to home, the earlier stratus has mostly dissipated. Consequently, we should be seeing temperatures rise quickly over the next few hours. Temperature forecast is on track. Still expecting just about everywhere to get to at least 80 and many locations (particularly DELMARVA and the i-95 corridor) making a run at 90. As depicted in the 12z iad sounding and mentioned by the previous shift, there is very dry air mostly above 800 mb. This could have two implications. First, dew points, currently in the 60s will decrease as the mixing layer increases. There is some question how deep the mixing layer will be, and there will be some mid level moisture advection. However, assuming the mixing layer gets to 850 mb, that should yield afternoon dew points in the upper 50s or lower 60s (using the 12z iad sounding as a starting point and allowing for additional moisture advection. The second implication of the dry mid levels is that initially (until we see significant moisture advection), this could serve to enhance the cap and limit convective initiation. However, i"m not sure it will be enough to weaken convection that is already ongoing. If the two clusters of storms mentioned above hold together, they could arrive in our region as early as 18-20z (2-4 pm edt). Additionally, as the capping erodes in our region we could see isolated or scattered storms develop in our region. As for the severe threats (which will continue into the evening hours). The best convective parameter space (largely a function of low-lvl moisture) will reside over the southern half of the area (more or less philadelphia southward), where MLCAPE of around 1500 j kg will combine with 40 kts or so of westerly shear to create the potential for an organized cluster of storms with damaging winds being the biggest threat (but hail is also possible). Low-lvl shear will be particularly unimpressive (low- lvl flow in general will be quite weak) so the tornado threat is negligible. Of note, some models (particularly the nam-nest) continue to advertise MLCAPE well in excess of 2000 j kg over much of the western part of the forecast area, which if realized would result in a more widespread severe threat. Currently think this is unlikely to occur as its pre-convective dewpoints seem too high given westerly flow and mixing of drier air from aloft... consequently think the hrrr instability will be closer to reality. Short term 6 pm this evening through 6 am Monday The severe threat continues through 03 or 04z (11 pm or 12 am edt) ahead of along the cold front and convectively enhanced shortwave. The front will move through this evening with modest drying (from n-s behind it) this is not a particularly impressive front from a thermal or kinematic perspective so drying will be gradual and precipitation will likely continue into the overnight. Additionally another shortwave is progged to approach the area after midnight which may spark another round of showers and even some thunderstorms over DELMARVA far southern |
nj late tonight into early Monday morning. That being said think the severe threat will wane with the loss of surface- based instability after about 03-04z. Given abundant cloud cover and high dewpoints, overnight mins will be warm (mid to upper 60s outside of the far north where upper 50s lower 60s will be possible) Long term Monday through Saturday A rather changeable pattern across the area this upcoming week with alternating days of (mostly) dry weather and some weak systems which will bring some sct showers and tstms. Right now, Mon Wed Fri are probably going to be the days with the lowest pops. Although there could be some morning showers across DELMARVA early mon. On wed, a couple showers psbl far N w. Tue will see low pressure and a front affecting the area, so showers and some tstms are expected with the greatest pops (likely) across the NRN areas. The models become somewhat varied by Thu fri, but the possibility for some showers will be retained with the GFS and ec showing some rains arriving late thu. Some much above normal temperatures will arrive during the middle of the week with upper 80s and low 90s in many areas. Up until then, above normal readings (4 to 6 degrees above) will be over the area mon tue. The much above normal will probably break late next week, with readings back near normal for Fri sat. Aviation 14z Sunday through Thursday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Today...VFR conditions are expected to continue through 18z. After 18z, there is a chance for tsra across the region. Any storms will be capable of variable and gusty winds, and possibly some hail. At this point, have a tempo group to include the threat with the first potential round of storms, but additional rounds of storms will be possible continuing into the tonight period. Winds will generally be from the west around 10 kts with occasional gusts to 15-20kts. Tonight... Showers thunderstorms possible in the evening, however vfr conditions under mid-lvl cloudiness expected to prevail. Winds shifting more northerly overnight. Outlook... mon tue...VFR much of the time. A few showers early Monday and tue. Wed thu...VFR wed. Sct showers later Thu with lower conditions psbl. Marine Sub-sca conditions are expected Sunday into Sunday night with seas generally around 3 feet and gusts up to around 15 kts.

There is the possibility for some SCA gusts later thu, but confid in this is low attm. Sct showers and tstms Mon morning, Tue and thu.
