  1. What the hell is fueling this convection inland? They should be around here. Jealous.
  2. The flow veers another 15° before midnight So any streamers that form should gradually move southward.
  3. I stand by what I said before. Maybe more like 5–6 pm now.
  4. See my post from before. Things should start exploding soon. Expect some extreme convection by this evening.
  5. Not enough instability (LI)until now. The energy was there but no trigger.
  6. With those numbers I would expect reports of very large hail with frequent lightning very lightly. possibly several strikes a minute in some cells.
  7. I’m very shocked. At 20:00 this evening I have 1078 J/kG of CAPE and -5 LI! Never thought I’d see those numbers outside of summer. Surprised there’s not any more activity in this thread actually.
  8. I’m actually quite shocked. Never thought I’d see CAPE numbers like that outside of summer. Wow! So excited for this evening.
  9. I have been waiting for the 6Z to say this. For all those worrying about shower activity: the LI (a measure of the instability in the air)is on a nosedive from now on which enables the convective available potential energy (CAPE) to be released this afternoon. By 20:00 I have 1080 J/kG of CAPE and an LI of -5! I cannot emphasise enough how rare it is the sea figures so high in winter. If we do not see some substantial showers with lightning activity by 4 PM, then I am a chocolate frog!
  10. We’ll start seeing showers like that once the colder air and steeper lapse rates arrive this afternoon.
  11. You’ve got another 11 hours and 30 minutes until it starts.
  12. The difference between midnight and 6 AM is enough to remove any chance at the coast.
  13. It’s always been forecast to do that. It will be back on Thursday.
  14. The coldest air starts to leave us by then. There is quite a sharp jump up in thicknesses, 850s and 500 mbar temperatures.
