Weather In March 2020

?>

It was a month of 2 halves as the rain relented bringing an end to the deluge which started in September last year! The continuous low-pressure systems which crossed the Atlantic slowed down as the difference between the polar and Atlantic regions abated. This temperature difference shows up in the AO (Atlantic Oscillation) it fuels the jet stream which in turn brings lots more storms over the UK and NW Europe. The second half of the month high pressure nudged into the UK and has stuck around, bringing the drier weather.

Looking ahead to April

The long-range forecasts for April look at continuing the high pressure dominated weather which started on the last third of March. The position of the high will depend on whether we will get lots of warm weather. This month is mostly looking like above-average temperatures continuing on how the year has gone so far.
