Polar Lows

[Gray-Wolf]

Hi Guy's!

Will someone with more weather nous have a look at the centre of the L.P. (that flung today's band of snow at us) and tell me it isn't starting to organise into a Polar Low.

I suppose by tomorrow a.m. we'll be able to see better but some of the recent infra red loops have me wondering just what will be visiting Scotland/Northern England later on Sunday/Early Monday.

I know that Polar Lows are a 'nowcast' feature but surely there are indications as to whether the formation of one is favourable and this is where my knowledge is lacking.

Ta in advance!

500mbs temps are there, but no other indicator is there. There is no chance of a PL. Just as there was no good agreement in Copenhagen, there will be no PL.

I have been stung too many times guessing that there will be a PL, there is no chance of it happening.

Thank's for the swift reply!

Having never seen one in the making the wrap around and convection had me wondering.....I'll still need that peep first thing tomorrow though!!! (Lamp post watching on the macro scale).

It may be possible...Mondy?? What's your take?

It's no PL, probably nor likely to be. However, it's one big low pressure system gathering pace north of the UK about to enter (or is) an northerly airflow. http://meteocentre.com/analyse/map.php?hour=0〈=en&map=AtlN

Will that band of showers move se and bring further snow to ne england? :winky:

I'd been watching it on the Eumetsat loop and it is only just wrapping around the low which has only dropped 1mb in the past 2 hrs.

It is progged to drop onto Scotland/N.England before exiting back into the north sea and ,judging by the showers into N Scotland, it's pretty cold in that airmass.

As posted on the Scottish thread, this from the earlier shipping forecast sums it up.

Low just north of Viking 988 expected Scotland 979 by midday tomorrow

It's not a PL, just a bog-standard LP entering northerly airmass.

Isn't that the route to a P.L.?

Anyhoo's, looks like another splodge of snow for the north in the least.

There was PL listed on a Meto fax chart I think two years ago. It later wasn't showing, but it's the first time I've seen one on a chart. Wish I'd saved the chart image!
