High Builds Into UK For Weekend, -NAO Persists Next 16 Days

Written by on August 21, 2014 in Rest of Europe, United Kingdom & Ireland with 0 Comments

After a wet, breezy and cool day, especially wet across northern parts of the UK, the showers thankfully ease as we head into the weekend. Low pressure gives way to high pressure.

It’s been a very persistent negative NAO pattern this week with a high west, northwest of the UK while a large low complex spins over Scandinavia. Chilly north winds have been blowing south over the UK hence the chilly feel and much cooler temps. Check out the mostly below normal UK this afternoon compared to Iberia.

The showers should ease as we head into Friday, Saturday and especially Sunday as the high over the Atlantic nudges east. This will make for a rather cold night Sat into Sun with patchy rural frost possible.

By the time we reach  late Sunday into Monday, low pressure approaches and sends a front into Ireland and the UK. Here’s the GFS surface charts into next week.
