Garston (Hertfordshire) weather

Headline:

Fine tonight, sunny and very warm Bank Holiday Monday.

This Evening and Tonight:

Dry with variable, often large amounts of cloud overnight and light winds. Turning locally cool by the end of the night in some rural spots should clear spells develop, but it will be relatively mild elsewhere. Minimum temperature 9 °C.

Monday:

Fine, dry and sunny on Bank Holiday Monday. Widely very warm in the sunshine with light winds, although developing onshore breezes will keep coasts a little cooler. Maximum temperature 27 °C.

Outlook for Tuesday to Thursday:

A band of rain, followed by scattered showers Tuesday, though still warm or very warm. Further spells of rain or showers Wednesday and Thursday. Occasionally breezy and feeling fresher.

Low pressure is expected to largely dominate through this period, bringing bands of rain or showers to most if not all parts from time to time. Some heavy rain is possible at times, especially in the west, but this possibly occurring more widely at times. Periods of windier weather are also likely. Confidence in the details remains on the low side, something not untypical at this time of year, largely due to the potential for further systems to develop in the tropical Atlantic, which can have profound knock-on effects on the weather patterns upstream of and over the UK. Temperatures should generally be around average, likely with some day to day oscillation, depending on sunshine amounts.

Most signs indicate low pressure will continue to dominate initially, and therefore unsettled or changeable weather looks more likely. This brings potential for periods of strong winds and spells of rain, but with spells of fair weather in between. The south may turn more settled and drier as we head further into September. Confidence through this period remains low. Temperatures are likely to be near to, or slightly above average overall.
