Bank holiday low

Courtesy wxcharts.com

Both the GFS and the ECMWF models are promising a low for Bank holiday Monday. This looks like the same low I mentioned the other day at T+216. The ECMWF variation is deeper (986 hPa) and runs ENE across southern Scotland during the day. The GFS variation takes a much shallower low (1004 hPa) ESE across northern Ireland and into the southern North Sea. Both models are forecasting snow across the high ground of Scotland, and the ECMWF potential blizzard conditions across the Grampians. Still, until the new generation of supercomputers arrives, T+132 is still well out of range of any NWP Model in the world today. One thing is certain Monday doesn’t look a great day for a barbecue, which could be cold, wet and windy.
