Since VSA members sometimes fly at Montague and Truckee, I have created this page to include links specific to those locations.

Boundary Layer Information Prediction – BLIP MAP

Regional Atmospheric Soaring Prediction – RASP

  • Hollister Weather page
    • RASP for Byron and south – be sure to look at the products under the “Loop” column – very impressive! – especially if you observe the convergence lines! How easy is to follow those lines? I hope it doesn’t take the ‘joy of discovery’ out of soaring for you. With those products, you can really decide where you may be capable of traveling to.
    • RASP for Sierra Range
      • Links to other BLIP pages:
        • BLIP Overview Page – Select “Regional Maps” for charts with descriptions.
        • BLIP Viewer – For California and Nevada (Important Note: If you are not able to load an image from this link – first go to the above link (BLIPMAP Overview Page), and Register!, and then you will be able to use this shortcut link.
        • NAM/ETA Model BLIPMAP – Scroll down on this page see NEWS, Info on registration, maps, etc, selection of products, descriptions, etc.

 

Soundings –

Current data, Webcams, TFRs

Forecast Chart Models –

  • Golden Gate
    • NCEP upper air charts. Use the /GFS model/ North America/ Loop All/ for 18Z, for whichever product you want to review.
      • The 700 mb product is 10.000 ft and indicates heavy moisture in dark green, and has wind arrows.
      • The 500 mb is 18,000 ft and indicates steering forces with vorticity in colors, and has wind arrows.
  • Wunderground
    • wunderground.com/ – See tabs – Current, Forecast, Models, etc. This site is better than UNIYSYS charts as listed next (RUC, NGM, NAM, etc)…

Soaring Forecast for Reno

Sat Photos

Conversion of C to F

Conversion/ equivalents of temps C to F. Some memorable pairs:
10C=50F 15=59 28=82 35=95 40c=104f
or recall any one of these references:

20=68, 25=77, 30=86, etc.

To adjust, add 1.8 to the F for each 1 deg change in C
The Relationship: each change of 5C, equals a change of 9F
