  1. I have found out what happened by searching TDWR on twitter! there was a link to this news release from NWS: weather.gov/media/notification/scn19-82tdwr_terminations.pdf The TCLT radar was the first to change which made it seem to me as though some kind of a partial outage was happening.
  2. I am hoping to find out which websites or phone apps offer reliable access to TDWR imagery! Being able to see weather as it happens at this resolution really is amazing; I have been using wunderground for many years; as it does offer access, but it is becoming unreliable. What else is out there?? :) :) Thank you so much in advance!!
  3. Is there any information available about the downtime of some of the Charlotte TDWR components? For radar, .60° 250 NMI is still fully in service, but, the other available options display that they have been down since November 19th. https://www.wunderground.com/radar/us/nc/charlotte/clt Rainfall accumulation products also seems to have been down since the same time. I am interpreting it to be the radar hardware itself not transmitting these bands and products perhaps due to updates. Please let me know if this is incorrect, and of any better methods for accessing this TDWR compared to wunderground!!
  4. My apologies calculus!! :) I know what you are saying: I think it is because I post so infrequently (a bit over 200 times since 2012) that i can stumble and hedge when trying to describe something that I don't fully comprehend! In this case I tried to choose my words carefully because I didn't want it to read as though i thought that the forecasts were inadequate! :) I have found a clearer way to describe the phenomenon since the post which is that Barry and this system, to me resemble the monsoon depressions that occurs in some places globally but are not considered to be an Atlantic phenomenon as of yet. https://en.wikipedia.org/wiki/Monsoon_trough#Embedded_depressions
  5. Yes; it is a rather complex troughing situation, for which the discussions and forecasts have become more abstracted! The presentation overall is quite amazing to see!
  6. Yes, i saw that: it might be fixed now with the most recent update. What seemed to have happened was that the new updates were accessible through the 2, 3, or 4 clickable number links depending on where they ended up each time, which would normally contain just-prior updates)! It may have been that the Wednesday update was stuck at 1, causing new updates to be placed behind it.
  7. This front will actually stall which will be interesting to watch! Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1039 PM EDT Mon Jul 29 2019 .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... As of 200 PM Mon: Return flow around the Bermuda High will continue thru midweek. Tuesday night a cold front will push across the Appalachians in conjunction with a well defined upper trough. This warrants a slower than usual decline in diurnal convective chances. However it seems the CAM guidance responds to the relatively high LCLs by depicting little overnight activity. So even though PoPs were allowed to linger into the night, chances are not especially high. That trough effectively will remain in place over the Eastern Seaboard thru the remainder of the period, maintaining better midlevel lapse rates than we normally experience this time of year. Likely PoPs result Wed aftn over the mountains and in a portion of the Piedmont where storms will be able to propagate. Again Wed night, with MCVs potentially rotating thru the upper trough, a small nondiurnal PoP is included in the fcst. Dewpoints recover a little bit Thu compared to Wed, so likely PoPs result in most areas at peak heating that day. Temps overall will be seasonable: slightly above normal Wed but near normal Thu under more cloud cover. Deep layer shear will remain fairly weak despite the trough, so slow-moving storms producing heavy rain will be possible any time they develop during the period. Drier air will be present aloft behind the front on Thursday, with sfc-midlevel delta-theta-e values becoming supportive of a wet microburst threat. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... As of 155 pm Monday: Starting Thursday evening with the 500mb pattern showing a trough over the East and a ridge over the Rockies and western Plains centered over New Mexico. The trough axis Thursday evening will be from Ohio to Alabama. The axis is forecast to shift a little east to being over the Appalachian mountains over the weekend and into early next week. The wind flow is forecast to be less than 10 knots up to 700mb through the medium range. The stationary front over our region will continue to slowly dissipate. A tropical wave that is currently over the eastern Caribbean Sea is forecast to move to somewhere near Florida over the weekend and would contribute to the amount of moisture over the Southeast. If this system were to track more directly over our area, we could get quite a bit of rain. Too early to say at this point as the system has not yet formed into an organized low pressure. This extended period of wet weather could add up to a saturated ground in some areas. The GFS and ECMWF diverge a bit toward the middle of next week as the GFS brings a closed low SE toward the Great Lakes. This would further serve to reinforce the longwave trough. The EC has the trough lifting some as the western ridge builds a little more east. Max temperatures will be 3 to 5 degrees below normal due to the cloud cover and Min Temps will be near normal.
  8. The technology may still be somewhere in the future. Yet: if there was ever a storm system that should be part of modern experiments towards figuring out how to prevent a PTC from stabilizing or to induce weakening at key stages that would thus cause it to dissipate as much as possible, this is it. Again it is possibly still too early in history, and whichever the coalition of scientists and group efforts would be, they would not want to risk having the opposite effect with their methods.
  9. Glad to share a surprising overview, and a close view of a popup riding along!!
  10. There is some stalling occurring between waves: edit: continued radar view Definitely a unique day temperaturewise! There is a warm front on the move up near the Canada/US border which seems to have a powerful enough effect!
  11. It is possible to make bookmarks that directly lead to an animated GIF of the wunderground radar!! Basically, you can configure the settings through this page, including changing to a different radar site. https://www.wunderground.com/weather-radar/united-states/nc/raleigh-durham/rdu/ Mainly I would recommend setting the number of frames to 10 unless you prefer fewer! At the very bottom of the dark gray panel is the Save Image button. You can also right click the Save Image button and open a new tab if that is possible in your browser! Either way it will hopefully open a GIF all by itself, and you will be able to make it a bookmark! Visiting the bookmark on another day is somehow able to run all of the same settings that you initially selected and produce an up to date new radar image!! And of course, you can set up different zoom levels and radar angles, then, use the Save Image option again and you can bookmark those too!
  12. Yes; Brick and others have been mentioning over the past few years that the once certain seasons for severe, especially autumn, have changed in that regard. I feel like it is at least a guaranteed interesting spring in terms of unusual weather systems, although I'm not sure if any would be severe, maybe just different enough to be noteworthy! I do think that there is at least a chance of a few to several colder wedge days during March and April.
  13. This wind map format may be helpful: (Surface winds:) https://earth.nullschool.net/#current/wind/surface/level/orthographic=-88.55,38.14,3000 (850) https://earth.nullschool.net/#current/wind/isobaric/850hPa/orthographic=-85.59,36.88,3000/loc=-80.532,33.711
  14. The trough over CONUS is definitely digging: Wide view GOES 16 water vapor loop Copy and paste this text below for full size image: https://i.imgur.com/isUw2M7.gif
  15. Wide view GOES 16 water vapor loop; multiple days This image has been made with the College of Dupage toolset which iam glad exists! It is interesting to see the evolution of all of the systems in the area all in one view. For example, the broad retrograde low over the eastern Gulf states and Bahamas has slowed down quite a bit but has continued activity.
