  1. ENH risk nudged westward a tad on 1630z OTLK towards i81 corridor
  2. 02z HRRR has some explosive development in the i81 corridor at teh end of its run that looks like it matches the 00z NAM Nest a bit
  3. 00z NAM Nest has a large UD Helicity Swath just north of DC metro around 19z-21z (basically IAD to BWI)
  4. Bye Cindy Remnants Of Cindy Discussion Number 16 NWS National Hurricane Center Miami FL AL042023 1100 PM AST Sun Jun 25 2023 Satellite imagery this evening shows that the low-cloud swirl associated with Cindy has again become void of deep convection. In addition, imagery animation and scatterometer data indicates that the system no longer has a closed circulation. Thus, the cyclone has degenerated to a tropical wave or trough and this will be the last advisory. The initial intensity is set to 35 kt based on the scatterometer data and satellite intensity estimates from TAFB and SAB, and it is anticipated that the maximum winds will drop below tropical-storm force during the next several hours. The initial motion is 315/12. The remnants of Cindy should continue a general northwestward motion for the next couple of days, and then turn northward on the eastern side of a deep-layer baroclinic trough over the eastern United States and the western Atlantic. In the short term, there is little chance of any regeneration due to continued southwesterly vertical shear. However, after 48 h or so, the shear should diminish, and there is a chance that Cindy could regenerate after that time near or north of Bermuda. However, the model support for this has decreased over the last 24 h, and currently there is not enough confidence in regeneration to explicitly show it in the forecast. This is the last advisory on Cindy by the National Hurricane Center.

  5. I'm not buying the big mixing out of the HRRR... southerly winds and flow should keep DPs 65+
  6. Wouldn't mind the 18z NAM NEST sim radar around 5pm tomorrow
  7. A more cellular event could lead to a better chance of large hail over damaging winds

  10. So where are we on here? Still Yoda level? Or higher?
  11. Afternoon AFD from LWX... and here we go @Eskimo Joe @high risk SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Closed upper-level low pressure will remain over the Great Lakes Monday and a potent jetmax associated with this system will move into the area during this time. This will cause the wind field aloft to increase while heights fall. A surface trough will most likely setup east of the Allegheny Front due to differential heating. Showers and thunderstorms are most likely to develop along the surface trough during the early to mid afternoon hours (approx 16-18z) before propagating eastward (additional showers and thunderstorms are likely west of the trough as well due to the breaking capping inversion from falling heights). Thunderstorms are expected to intensify as they propagate eastward, possibly congealing into linear segments that produce more widespread wind damage. Deep layer shear is progged to be around 25-40 kt, and mid-level lapse rates will be steep due to the falling heights. SBCAPE is progged to be around 1500-3000 J/KG with the highest amounts east of the Blue Ridge. DCAPE will most likely be over 1,000 J/KG for many locations, enhancing the threat for downbursts. Also, some of the fattest CAPE in the soundings is progged to be around the -20C level, suggesting that there is a potential for very large hail in addition to the damaging wind threat. Veering profiles also suggest that an isolated tornado is possible as well. Please pay attention to the latest forecasts for Monday afternoon/evening, and be prepared to seek shelter if warnings are issued. The most likely timing for severe storms is around noon to 4 PM west of the Blue Ridge Mountains, and 4 PM through 8 PM east of the Blue Ridge Mountains into the metro areas, and perhaps lingering until around 9 or 10 PM toward southern MD and the Bay. Convection should dissipate later Monday evening. However, if we do not get widespread convection during the afternoon/early evening, there is a threat for isolated to scattered severe storms well into the evening because the atmosphere will not be worked over. Overnight, most of the time should turn out dry with just an isolated shower or t-storm possible.
  12. This was from this morning LWX AFD... haven't seen them mention destructive winds before SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... After a lackluster start to the severe weather season, things quickly begin to change as a robust upper trough sweeps through the Ohio Valley to Mid-Atlantic. Presently, the upper low is situated over the Upper Midwest while eventually racing toward the east-southeast during the next 12 to 36 hours. With warm sector temperatures rising into the upper 80s/low 90s and dew points reaching the low 70s, ample instability will be available for convective development. Depending on the forecast model, surface-based instability nears 3,000 J/kg, accompanied by unusually steep mid-level lapse rates. With such lapse rates into the 7 to 8 C/km range, there is an increasing threat for large hail, especially from the D.C. metro southward. Additionally, large downdraft CAPE values are evident in forecast soundings which supports damaging to locally destructive winds. The latest model suites favor early afternoon convective initiation over the terrain as well as along a well established lee trough. Seasonably high CAPE values should allow rather quick development of updrafts. Within a couple hours after initiation, high-resolution models favor upscale growth into a eastward propagating squall line. The Storm Prediction Center has placed areas east of I-81 in a Slight risk for severe thunderstorms, with an Enhanced risk grazing Spotsylvania and King George counties. Depending on how subsequent models and observational data indicate, some expansion of these threat areas are possible. With an above average precipitable water air mass advecting into the region, there will be some threat for flash flooding. The cold pool driven thunderstorm activity should keep convection on the move. However, a quick inch or two is possible within many of these storms. A Slight risk continues from the Blue Ridge eastward, but especially over the DC to Baltimore urban sprawl. As the cold front does not arrive until late Monday into early Tuesday morning, some of these thunderstorms may linger into the overnight hours. Nighttime low temperatures will range from the 60s to low 70s.
  13. Arlington, VA is in the hatched while DC is just outside lol https://www.spc.noaa.gov/products/outlook/day2otlk.html
  14. USA getting lucky late with a goal late against Jamaica... I know some of the big guns aren't playing, but still, they have been struggling at times
  15. 00z HRRR at range of course, but that's pretty nice looking radar forecast from hours 43-48 Wouldn't mind the 00z NAM NEST or the 00z FV3 either
