  1. Glad you got it. No you're not missing anything. The verification charts probably don't go back as far as the date you entered. And I'm not sure if the verification links even show up on days with no reports.
  2. I'm using Chrome and yes I get a blank page just like you show when I use the link you posted. But the link I posted works just fine me. If you're using this link http://www.spc.noaa.gov/products/outlook/ and still getting a blank page then I'm not sure what's going on. Sorry...
  3. Did you try the link and directions I posted above? This, for example, is what I get when I enter date 20110427 and click one of the verification links on the following page. Is this not what you're looking for?
  4. http://www.spc.noaa.gov/products/outlook/ At the bottom of the page is a section called "Retrieve Previous Outlook". Enter a date then the next page has links for verification overlaid on the outlooks.
  5. Major Hurricane Irma- STORM MODE

    I dunno, I probably made a mistake somewhere, but I get about 57kts?
  6. Major Hurricane Irma

    I'm no expert but my understanding is that this means the model itself isn't fully accounting for the effects, some negative and some positive, that the storm has on the sea and vice versa. For instance, upwelling of cooler water, ocean wave surface drag, and sea spray enthalpy flux, etc. The negative feedbacks being more dominant when not modeled allow the models to overdeepen cyclones under otherwise favorable conditions. I'm guessing increased resolution may then exacerbate the issue...
  7. Severe Weather Risk This Weekend

    I agree, some were questionable. I admit I wasn't following closely tonight but in FL of what I did watch I didn't see anything that I considered to be a no-doubter like in GA. It was mentioned earlier and I see this sometimes with supercells and mesovortices that bugs, bits of vegetation, and other smallish debris from the inflow gets drawn into low level mesocyclone/vortex and lowers the CC around the velocity couplet. And if NWS offices were discussing what they truely believed were TDSs in chat why weren't they tagging the warnings?

    I'd have to do some digging to be sure (which I'm not going to do), but that may be highest observed SBCAPE ever in the US or at least close to it.

    Go check out the ILX sounding.
  11. This may be what you're looking for. But only has a 10 day archive. http://www2.mmm.ucar.edu/people/tomjr/files/realtime/diagnostics.html There's a set of charts for QG height tendency for both the vorticity advection and the differential thermal advection terms. You might note that the absolute height fall/rise contribution isn't computed. Just the contribution of the individual right hand terms without solving the Laplacian.
  12. Capture of [surface?] Low

    You could always ask the poster from your example what was meant. As for the other sources, without reading the context, I might speculate that it was in reference to the concept of "phase locking" of upper and lower level PV anomalies and their mutual amplification. Just a guess...

    I think the 0z Pittsburg sounding already measured a 6000m 500mb height right?
  14. Drought in Lower Lakes/Ohio Valley

    Had this problem last year myself in St. Louis. Soil in my area is expansive and contractive depending on moisture content. Dry conditions penetrated far enough down that foundation footing began to sink especially during the end of the very hot dry summer. The settling was minor for me. Doors and windows not opening & closing properly, cracks in drywall especially near door frames, drywall tape disbonding at the joints, and cracks in the basement foundation. We decided to fix the problem at that time since water was coming in from the basement cracks. Although the settling was relatively minor the fix was expensive! $13K for pier installation (the home was lifted to correct door & window problems). I live near the Missouri River and average pier depth to bedrock was about 25-30 feet. This seems to have fixed the problem and stopped the settling. Thankfully we fixed the problem last year otherwise we would be dealing with a major settling problem this year. I see several signs that the soil continues to contract around the home significantly. St. Louis is on day 24 of 90+ degree days. Record is 28 and we should easily beat that given the foreast. Already had a stretch of 10 consecutive 100+ days (including 8 new record highs). Voluntary water restrictions are in place, but mandatory restrictions are looming.
