  1. Very strong winds develop just offshore Maine/Massachusetts as this system pulls north. The NWS has a high wind warning out for the Boston area with 20-30 mph sustained and 55 mph gusts. Attached is the latest HRRR 10 m winds. http://i.imgur.com/eoApSgJ.png
  2. As this system pulls north, it is going to bring plenty of warm air and rapidly intensity. Sustained winds near 50 mph are forecast for the Atlantic. From our 4 panel model viewer... http://i.imgur.com/yyqDM7r.gif
  3. Hi Geos, thank you, we appreciate it. You can find our graphics at http://www.weathercrossing.com. Though you may have been asking our physical location...We are in Sacramento CA.
  4. I realize this don't go to the end of the system...but the WRF models (NMM & ARW bottom panels) have the rain/snow line much further north. Total Snow: NAM (top left), 4km NAM (top right), ARW (bottom left), NMM (bottom right) http://i.imgur.com/YC2HAks.png
  5. Good consistency between NAM runs. 12Z vs 00Z total snow. 18Z looks very similar. http://i.imgur.com/UP0DOY8.png
  6. And so it begins... http://i.imgur.com/pbkgy5l.gif
  7. As this low moves eastward the gradients really tighten up. 10 m sustained winds will meet or exceed 25 mph with extremely heavy snow. http://i.imgur.com/4mABsIu.gif
  8. A look at the snowfall in/around Denver, CO shows 6-9 inches. The NMM is a complete outlier! Any thoughts? Is this typical of this area? http://i.imgur.com/348tmh1.png
  9. While there is certainly a threat for sever weather in the South Feb. 1-3, the area of greatest instability is shifting further east. NAM Model Lastest (31 12Z): Top left Oldest (30 18Z): Bottom Left http://i.imgur.com/G5JR82e.png
  10. Latest snowfall totals from our 4-pannel viewer (GFS left, NAM right). Tracks are in much better agreement now.
  11. Here are the latest GFS and NAM tracks....there are still some large differences.
  12. There is a real threat to the East Coast for this upcoming storm. The GFS has been fairly consistent with the general precipitation totals. Additionally, the 13km GFS output (18Z) shows 40+ mph 10 m winds well inland in New Jersey. 50+ mph along the coast!
  13. The active weather patten shows now sign of letting up! Rainfall for the next 10 days (GFS 20150115 00Z run).
  14. Over these next 10 days the Jan. 01 12Z GFS brings in at least 7 storms to the Pacific Northwest. Sunday night-Tuesday morning looks particularly heavy for northern California. 850mb temps will be around 5C in this area so this will be quite a warm system! http://weathercrossing.com/forumposts/20160112/156_precip3_centralwest.png http://weathercrossing.com/forumposts/20160112/156_temps_850_centralwest.png
