  1. Turning back to Sleet here now after rain since dawn. Temp 2.9C DP 0.7
  2. Moderate Rain. Temp 2.5c DP 0.2 Pleased for those out west who have received “the goods”. Enjoy
  3. Moderate Snow . Shorne West. Temp 1.4c. dP -1.8c . A light covering on everything.
  4. Yes I think your statement sums up Winter 18/19 very well. The absence of “knowledgable” posters as of late would seem to endorse these comments also. Ive been on here since 2004 and can count the number of succesfully “counted downl snowy synoptics on one hand. Dozens of signals all over the place but ive not seen one yet that can be relied on to deliver the goods in the reliable timeframe. Yes they may increase “potential” and “probability” but thats it. Global weather science is fluid and has infinite outcomes. How hard we try i still think we are just scratching the surface of our understanding at this time. Anyway back to the here and now and with Tropospheric propagation about to develop in a favourable MJO, Tropical Forcing, +MT, EAMT, Solar minimum environment, if the HLB fails to build and hold back the rampant Jetstream in the next 7 days, I for one will be switching off signalling and leaving any late winter / early spring snowy fruitfulness down to chance.
  5. Remember it well . It was about 26th January 2004....i was stuck around the back of Biggin Hill after a tree collapsed across the road. We had about 3 inches of snow in 20 minutes. The temperature dropped from 5c to 0c within minutes.
  6. Interesting comment from Mike Rantanen……. "The decelaration of stratospheric winds is slowly propagating downwards. ECMWF is now forecasting an easterly zonal mean zonal wind at 50 hPa (~20 km altitude). Note that in the #SuddenStratosphericWarming of 2018 the wind at 50 hPa never reversed".
  7. Yes it does seem that the GFS super computers cannot resolve the post SSW impact for the North Atlantic. Despite the positive signals all over the Strat & Trop, the reviving PV definitely seems to want to head home to its North American lair.
  8. Met office probability for colder spell now end of January. That’s just over a month later than they originally stated. Big fail for them anyway you paint it
  9. Chris Fawkes just presented the longer weather outlook on the “propaganda” channel. Mentioned Mild 12 times i counted. For the following week turning ‘cooler’. ....lol
  10. The MJO has been on the sherry, rapid increase in amplitude on the 06z ...…… Click on the GIF for todays update
  11. I think today is going to see the start of some mouthwatering charts. The zonal mean zonal wind at 10 hPa 60N at midnight is (GFS analysis): 27.3 m/s . Its going to drop like a stone for the next few days , we await the Trop response.
  12. A couple of questions .. Does anybody have historical knowledge of how quickly a raging jet stream deaccelerates when a SSW occurs? And does the warming itself create inertia that slows it down, or does the Jet just “freewheel” until it loses its energy?
  13. Zonal wind speed at 60’N increased to 28.6 at midnight. This was forecast and could indicate why NWP is showing such strength in the Jet stream. The good news is that this will fall like a stone from today to a possible reversal around the 28th. This should severely deflate energy in the jet stream around the New Year. The question is whether the models have factored this in?
