Freezing-Point

Light covering here. A promising shower heading down through Northumberland all but pettered out by the time it reached here. However... a reminder that NE is great for snow if the wind direction is right. NW or NNW wind is dry and sunny every time!

Yes. As the chart only shows 12hr intervals, I take it that the feature running down the coast was further north earlier

Showers seem to be making their way further south in NE Scotland now....

They have to give one as there is a risk of snow. Does not mean you will get it due to the nature of showers... however, very occasionally it goes the other way and there is an unexpected snow outbreak...this is rare.... unless there is a NE'ly

You can see why on the FAX chart

Go here. Choose UK Snow risk. You can see there is a moderate risk for NE coast from 3am, then a higher risk for North Yorkshire after 7am. TBH its going to take a change in the predicted wind direction for showers to hit NE coast. Be very lucky to get even one here.... Check this again at about 10pm tonight...

-5.3 here....

You can see in the charts the wind direction buckling to what looks like a true northerly for a time in the early hours... before shifting to a NW later in the day. The devil will be in the detail! If it does make a northerly, how long for will determine which parts get some snow. I would not be expecting anything inland at all. Coastal regions favoured. Especially N.Yorks.

feb+1991+weather+charts+uk - Recherche Google WWW.GOOGLE.COM The real beast!!!

NE'ly is best. The last easterly "beast from the east" was only good for snowfall well inland... Feb 1991 was the last time I saw a real potent beast. Shower after shower. White out conditions and over a foot of snow to the coast by morning.

We are in the warm sector. Colder air is already in S.Scotland heading south. Watch the radar as the transition in forecast to bring a band of precipitation down with 100% chance of being snow by midnight (according to gfs!) Then before Friday, FAX chart showing chance of a couple of features which could bring some snow....

Problem with this blast is its not been a direct Northery. More of a NNW'ly. Problem with an easterly is the airmass needs to be very cold to get snow on the areas 10 miles or less from the coast (unless you have elevation). IMO the very best direction for snow showers is a direct northerly OR even better NE'ly where you get streamers forming (2010). The airmass does not need to be as cold to get snow right along the coast. Only issue would be if you are well inland!!!

I don't think that matters in a westerly flow. (for North East parts nearer the coast) Its your elevation.

From my memory... decent cold spells are always downgraded in the days leading up to the incursion.... and often upgraded in the 48hr period...then often last longer than expected...as the saying goes...get the cold in...
