The showers that are expected to move north out of the channel before the main system arrives, could they be wintry initially? Considering its 0.9'c here currently.

Given that no-one else has replied...you're missing an indication of the temperatures at a pressure height of 850hPa represented by the shading.  Ground level is taken as an average of 1000hPa (1000milibars or 1 bar/1 atmosphere), and, as pressure decreases with altitude, so does the figure of each pressure height level.  Of course, surface pressure isn't alays 1000hPa; in deep areas of low pressure it can get down to 950hPa, and, under high pressure areas, it can be 1030hPa, so each pressure height will vary as well - a given pressure height will be closer to th ground when there's low pressure as the atmosphere occupies a slightly shallower layer than under high pressure; this is what is meant in model discussions when people refer to lower heights.  This then means that, under high pressure, the opposite is the case - a given pressure height is further from the ground.  As an average, 850hPa is around 1500 metres (5000 feet) above sea level.  Colder air at a given pressure height suggests low pressure (heights are lower), whereas warmer temperatures suggest high pressure (there is an exception in Greenland and Siberia in winter where surface cold air causes a surface high which is colder than low pressure would be).  Otherwise, the lines are simply isobars as you'd find on a weather forecast chart.

Thanks for your reply

Could someone explain this chart to me in idiot terms. I'm trying to teach myself using the internet....

I'm new and trying...

Current video forecast by the MetOffice is taking the snow eastwards out of Wales across the Midlands and into Northern England.

Whats the current tracking of Sunday's low? Is it possible that it will swing in and track SE into Sunday evening drawing in the colder air again. Thus turning Sunday's rain wintry?
