Model output discussion - proper cold spell inbound?
SMU replied to Paul's topic in Forecast Model Discussion
What we are seeing is the models continually backtrack on any Atlantic influence with each run- We have 2-3 cycles this coming week where the Atlantic bites into the UK & each time it’s swerved away North & south - Now the 4th one ( around 156-168 ) is coming into view the same thing is happening - The net is that the cold spell is elongated in the ENS means every day The Debilt ENS have been classic going from a 1 day affair to about 7 now... & so it goes on... The Atlantic will arrive eventually but not as fast as the models predict— If the ECM landed this week then plenty of snow for England in particular by Thursday... -

ECM 144 doesn’t have the Atlantic making much impact- looks exactly like the IKON 00z ! -

Why don’t you look at the decent models rather than just blindly following the GFS ... UKMO / ECM will have you all snow unless your right on the NW facing coast - which as with any facing coast runs the risk of having cold moderated- ECM 72 has -11c air in the NW FWIW- -

Over estimate frontal snow perhaps / under estimate convective snow- Parts of Kent / EA have had 10cms snow before yet the models didn’t have a thing or record a thing ! -

It can happen PTB 8 ( the most extreme ) shows this at 114 with the Atlantic hitting the buffers west of Ireland -

uKmet 144 messy is is great when you have deep cold at the surface, almost stationary air - means when PPN arrives ( & it will ) it’s very slow moving note the Trough over England @144
