(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 221951 afdphi area forecast discussion national weather service mount holly nj 351 pm edt Wed may 22 2019 Synopsis High pressure will slide offshore this evening. A warm front will cross the region tonight followed by a strong cold front on Thursday night. High pressure will return for Friday into Saturday. Another cold front will drop down into the area late Saturday into Sunday, stalling nearby through early next week. Near term until 6 am Thursday morning The main story tonight will be showers behind the warm front lifting north over the region. Even though this will be a late night (mostly after midnight) event, a few rumbles of thunder are possible once the warmer air mass arrives. The boundary layer will be relatively dry, so may preclude any heavy downpours through the overnight period despite increasing precipitable water values. Short term 6 am Thursday morning through Thursday night As the low pressure system over the great lakes slides east, our region will see first a pre-frontal trough in the late afternoon evening, followed by a cold front late Thursday night. Although showers, and possibly a thunderstorm or two, will continue to be possible in the warm sector through the morning, the main round of storms we are concerned about are storms that are expected to develop along and ahead of the pre-frontal trough late Thursday afternoon into Thursday evening. Some of these storms could be severe. Most models depict ml CAPE values near or above 1000 j kg in the 21 to 00z time frame along with 0-6km bulk shear values of 40 to 50 kt. Not only is this a significant amount of shear, but model soundings depict plenty of veering with height (especially within the first 3 km). This further enhances the risk that updrafts could be persistent. There are a few potential caveats. First, low mid level clouds may not erode through the morning. This will limit diurnal heating (in anticipation that this may be the case, have gone with the cooler guidance for highs on Thursday), which would limit instability CAPE values. Secondly, related to the first caveat, the NAM depicts a low level inversion (around 900 mb) which never fully erodes through the day (unlike the GFS which depicts this eroding between 21 and 00z). Even if we are cooler and the inversion stays in place, I think we will continue to have at least some severe threat as lift along the trough could be enough to lift elevated parcels above the inversion. The final caveat is that remarkably, model soundings are depicting several dry (and one very dry) layers through the afternoon and evening. This means the lcl will be higher than normal, and will have an impact on the risk for wind, tornado, and heavy rain. Speaking of hazards: damaging wind: this looks to be the primary hazard thanks to a low and mid level jet, and plenty of shear. The low level inversion mentioned above may limit how efficient the mixing is down to the surface, but the dry levels will help to increase the risk of downbursts thanks to an increased risk of dry air entrainment. Hail: severe hail (1" in diameter or greater) is certainly possible, especially if we warm up as much as what the GFS is depicting and are able to realize the higher CAPE values. The highest threat for hail looks to be over DELMARVA and far SE pa where the highest cape values are possible. Tornado: the veering wind profiles increase the risk for rotating updrafts. However, as mentioned above the LCL will be higher than normal which could limit the threat for tornadoes. Heavy rain: although localized downpours will be possible, storms should be moving fast enough to preclude a widespread flooding threat. Storms should move off shore by late Thursday evening. A cold front is then expected to arrive in the region during the pre dawn hours on Friday. Long term Friday through Wednesday High pressure slides across the great lakes region and into the mid- atlantic for Friday, sliding offshore on Saturday. This will allow us to remain dry across the region and have a couple of nice days before the next system arrives. Temperatures on Friday and Saturday should generally be in the 70s to lower 80s across the forecast area. With dry air in place and dew points in the 50s, it should feel quite nice outside during the day, although the dew points may start to creep up a bit on Saturday. With the increasing moisture combined with surface heating, we may see some scattered showers and thunderstorms on Saturday afternoon evening. A cold front will start to drop down from the northwest later on Saturday as the parent low tracks across ontario. The front sags southward through the region through the day Sunday and pushing just offshore Sunday night. The front appears to stall though and it looks like it has plans to hang around through the beginning of the week, which would keep our unsettled so we continue to mention some showers through at least Monday, when it looks like the front might start moving northward as a warm front. The models appear to be coming closer together for the Tuesday Wednesday timeframe but still have enough differences to lower forecast confidence. Once the warm front lifts north of the area on Tuesday, it looks to be fairly nice across the region with |
some warming taking place on Tuesday in the southwesterly flow and increased warming expected for Wednesday. There is the possibility for showers through this period but will keep any mention pretty low for now. Aviation 20z Wednesday through Monday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Tonight... MostlyVFR conditions are expected. Showers and even a thunderstorm or two are possible, primarily after 06z. Along the coast, winds will start southeasterly, but winds should shift to southerly by late evening with speeds 5 to 10 kt. Thursday... Conditions should startVFR, although ceilings through the morning hours could drop as low as 3000 ft agl. After 18z, thunderstorms are possible across the region. Gusty and variable winds will be possible in the vicinity of any storms. Southwesterly winds of 5 to 15 kt are expected through the day (excluding in the vicinity of storms) outlook... Thursday night... Storms should move east of the TAF sites no later than 06z. Conditions should return toVFR through the later half of the night. Winds should start southwesterly 5 to 10 kt, before shifting to westerly by 03z at 5 to 10 kt. Finally, an abrupt shift to northwesterly at 10 to 15 kt is expected after 06z. Friday... MainlyVFR conditions expected. Northwest winds around around 10 to 15 knots with gusts around 20 to 25 knots through the afternoon. Gusting up to 20 kt, becoming northeasterly and decreasing Friday night. Friday night... MainlyVFR conditions expected. North to northeast winds around 5 to 10 knots early then dropping off to light and variable overnight. Saturday through Saturday night... MainlyVFR conditions expected. Showers and thunderstorms possible from late Saturday afternoon through the overnight period with MVFR or lower conditions possible. Southeast to south winds around 10 knots through the day becoming southwest to west overnight. Sunday... MainlyVFR conditions expected. MVFR or lower conditions possible in showers and thunderstorms, mainly in the afternoon and evening. West to northwest winds around 5 to 10 knots, becoming more northerly overnight. Monday... MainlyVFR conditions expected. MVFR or lower conditions possible in showers and thunderstorms. Northwest winds around 5 knots. Marine Winds and seas are expected to remain below small craft advisory conditions tonight and into mid day on Thursday. Wind gusts near 25 kt and wave heights at 5 feet are possible Thursday afternoon and evening, but will hold off on issuing an SCA at this time as conditions look marginal and brief. Thunderstorms on Thursday evening will be capable of producing wind gusts above 34 kt. Outlook... Friday through Monday... Relatively quiet conditions on the area waters. Winds may gust near 25 knots on Friday. Seas generally around 2 to 4 feet on the ocean and 1 to 2 feet on the delaware bay. Rip currents... a low risk of rip currents is forecast for today, though a sea breeze is expected to develop this afternoon. Equipment The kdix radar is back online and repairs have been completed. However, it will be in a test phase through Thursday to ensure it is stable. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... None. Synopsis...
