UK WEATHER FORECAST 23/11/2018

Today has been cold in many areas, with minimum values close or below 0°C especially in England (values between -4°C and +2°C). Tomorrow a low pressure system will move between the UK and France (Figure1), causing unsettled conditions especially on the west (Cornwall, N.Ireland and W. Scotland). However, this system will drive milder air from the Mediterranean region towards the UK, increasing the temperatures.

Figure1. Synoptic chart for Friday afternoon (Met Office).

During the night possible showers are expected in Scotland (some snow on the highlands above 400-500 m), N. Ireland and S.W. England; drier elsewhere with some fog/low clouds especially in England. During the morning and afternoon scattered showers are still possible in the same areas, instead in Wales and central-eastern England drierconditions are expected with some clouds. Finally, during the evening, showers are still expected in S.W. England (especially Cornwall)  and Northern Scotland.

The minimum temperatures will increase, due to the overcast conditions, with values between (0-8 °C) in England (still some frost possible in central-southern England, but less than on Thursday morning), (4-7°C) in N. Ireland and (2-7°C) in Scotland. The maximum values will increase as well, especially in S.W. England. Are expected (6-12°C) in England, (5-8°C) in Wales and N. Ireland and (3-8°C) in Scotland.

Finally, the winds will be south-easterly in England and easterly elsewhere. No strong winds are expected.

UK WEATHER FORECAST 22/11/2018

Wednesday evening is showing temperatures close (or slightly below) to zero especially in England (Figure1), instead milder temperatures (6-8°C) are observed in Cornwall and N. Scotland. This is due to the clear skies, which increase the radiative cooling at surface compared with the previous days (when overcast conditions occurred).

Figure1. Temperatures in the UK at 21.00 UTC on Wednesday (Meteociel).

The night on Thursday and the early morning will see clear skies mostly everywhere, only few showers might be possible in N.E. Scotland. During the morning scattered showers are still possible on N.E. Scotland and also along the coast on E. England, sunny or partly cloudy elsewhere. This is due to an occluded front positioned just east of the UK and moving towards the Atlantic (Figure2).

Figure2. Synoptic chart for Thursday afternoon (Met Office).

However, this won’t cause intense rainfall, but only showers moving westward during the afternoon (towards central-western Scotland, N. England and N. Ireland); clear skies or only few clouds in central-southern England and Wales.

Due to the still cold temperatures, some snow is possible on the highlands and N. England at (400-600 m a.s.l.).

The minimum temperatures, especially in England and Wales will be close or below zero in several places, mostly between (-2,+4 °C). Also in Scotland (mainly on the highlands) temperatures could fall below zero. The warmest areas will be N. Ireland (3-7°C) and Cornwall (3-8°C). The maximum temperatures will be steady, with no significant difference with Wednesday: in England and Wales (5-9°C), in Scotland and N. Ireland (4-8°C).

Finally, the winds will be south-easterly in S. England and easterly elsewhere, moderate on the Irish Channel (25-35 mph).

UK WEATHER FORECAST 21/11/2018

Today has been cold and wet in many places, with showers and some snow on the hills, with temperatures (especially in England and Wales) below or close to 5°C most of the day.

Tomorrow, the weather will be still wet in Scotland, N. Ireland and N. England with the occluded front moving northward (Figure1); also in S.W. England showers are possible (notice the trough, Figure1). However, the winds will tend to turn from the south, with milder air replacing the continental, due to a low-pressure system positioned north-west of Spain. This will cause a slight increase in temperatures, especially in S. England, compared with today, though it will be still cold.

Figure1. Synoptic chart for tomorrow midday (Met Office).

During the night showers are still possible mostly everywhere, with the most intense precipitation on N.E. England and later in the morning on Scotland; drier in central-southern England, but with still some showers possible during the day especially in the South-west. Showers also in N. Ireland (especially during the night and morning) and Wales.

The snow limit will raise, during the day. However, during the night and early morning some snow at low levels (200-300 m a.s.l) might be possible (depending on the intensity of the precipitation) in S. England and Wales. Snow also in the highlands and N. England but at higher altitudes (400-500 m a.s.l). However, from the afternoon drier conditions are expected (especially in England) and by evening only in Scotland and N. Ireland could see still some showers, instead clear skies elsewhere.

The temperatures in the morning will be between (0-5°C) mostly everywhere, with higher values on eastern England, N. Scotland and N. Ireland (3-8°C). During the day, the maximum values should slightly increase in England (5-9°C) and be similar to Tuesday elsewhere (4-8°C). However, during the evening, due to brighter conditions there will be a decrease in temperature in England, with values close to 0°C in some areas.

The winds will turn southerly in England during the morning, and later in the day S.E. mostly everywhere. They will be light in England, and moderate in Scotland and Irish Channel (25-35 mph).

UK WEATHER FORECAST 20/11/2018

Today has been cold mostly everywhere, with maximum temperatures below 10°C and overcast conditions with some showers and snow at the medium height.

On Tuesday, the easterly winds will cause still cold conditions and there will be some showers, especially in England, with snow possible at low levels (notice the 528 dam in Figure1 on the south of England).

Figure1. Synoptic chart for Tuesday afternoon (Met Office).

During the night some showers are expected on eastern England and Scotland (snow on the hills), moving westwards during the day (showers possible also in Wales, Northern Ireland and southern England). However, the most important precipitation should be observed in England (North and east). Depending on the intensity of the precipitations, some snow might be possible at low-levels in southern England and Wales between the afternoon and evening. However, it will be wet snow (due to positive temperatures) and it will be difficult to see snow accumulation in the lower areas, instead few centimeters can be expected on the hills.

The temperatures will decrease, especially in southern England, with little difference between minimum and maximum values. In the morning (2-7°C) mostly everywhere, with the lowest values observed in southern England, Wales and highlands. In the afternoon, values between (4-8°C) with the lowest temperatures still observed in southern Egland and Wales (where snow at low levels is possible). Still, due to the positive temperatures (and precipitation not too intense), it’s likely to see only snowflakes at low levels.

Finally, the winds will be easterly over the UK, moderate on the east of England and on the Irish Channel (25-35 mph).

UK WEATHER FORECAST 19/11/2018

Sunday has been bright and chilly in the UK, with easterly winds especially in England. On Monday these will cause a further decrease in temperatures everywhere, due to the continental air mass coming from the east (Figure1). Moreover, this will cause and increase in cloud cover and some showers across the UK, with some snow expected on the hills.

Figure1. Synoptic condition for Monday afternoon (Met Office).

During the night and morning some light showers are possible on the east of England and Scotland, moving westward in the afternoon. Due to the cold temperatures, snow is expected on the hills in both Scotland, England and Wales above 500-700 m (depending on the duration and intensity of the precipitation).

The minimum temperatures will be between (3-8°C) mostly everywhere, with values close to 0°C in Wales, northern England and highlands. The maximum temperatures will decrease, with values between (4-10°C) everywhere (with highest values observed in N.W. Scotland and Cornwall).

Finally, the winds will be easterly, moderate on the English channel and east of England.

UK WEATHER FORECAST 18/11/2018

The easterly winds have caused bright skies and cooler temperatures especially in England, and on Sunday the situation will be similar, with high pressure over Scandinavia and easterlies over Central Europe and the UK (Figure1).

Figure1. Synoptic chart for Sunday afternoon (Met Office).

Sunny conditions with low humidity will last during the whole day, with no clouds mostly everywhere, but in Scotland, though with no rain.

Temperatures will decrease especially in England, instead Scotland will be still mild. Minimum temperatures will be between (3-7 °C) mostly everywhere, with some values close to zero in some low areas in England and Wales. The maximum will be between (7-11 °C) mostly everywhere, still possible 12-13 °C in western Scotland, north Wales and Northern Ireland.

Finally, the winds will be easterly especially in England and Wales (moderate on the English Channel) and south-easterly in Scotland.

UK weather morning 17/11/2018

The easterly winds have started blowing since last night, and as we can see from the satellite image comparison between this morning and yesterday (Figure1) the weather conditions have changed especially in England.

We can see how the fog and low clouds of yesterday, which were covering most of the country, have now reduced, with drier and cooler conditions. By the end of the day, brighter conditions are expected also in Scotland and Northern Ireland and the winds  will be easterly mostly everywhere.
