Heatwave to end with showers increasing – Thursday 15th June 2023 – Sunday 18th June 2023
Hi all,
The dry spell has come to an end, but only for those who caught the thunderstorms. There have been vast differences in what fell across parts of the region this week as those thunderstorms arrived. I’ve only measured 1.6mm whereas others, like Hindley and Hartcommon Golf Clubs, measured 38 and 40mm. That’s what we would expect over 2 weeks in June.
Over the last day or so we’ve picked up an easterly breeze, which has not only been gusty but has brought slightly lower temperatures and a less muggy feel at night as the humidity and dew point dropped. Unfortunately for those who hate the sticky nights, they are set to return as the moisture in the air increases and winds ease.
HIGH UV levels and HIGH to VERY HIGH pollen levels throughout the 4-day forecast.
Thursday: Another stunning day with plenty of hot sunshine. Not as windy as recent days, so temperatures lifting a degree or two. Fair-weather cloud will bubble up during the afternoon but I will be very surprised to see any showers. A warm night. Max 27°C Min 15°C
Friday: The high pressure that’s kept us sunny for the last few days will start to lose a bit of its grip and winds will swing south or south-easterly allowing it to become more humid. With a bit more instability, the cloud that bubbles up later in the day is likely to set off a sharp shower. Stuffy night awaits. Max 26°C Min 17°C
Weekend: The heatwave ends and could the heavens open again.
Saturday: Low pressure will be nudging closer from the south-west, similar to a week ago. So, more in the way of cloud after a sunny morning. Scattered showers into the afternoon, some thundery with torrential downpours. Max 24°C Min 16°C
Sunday: Definitely looking more unsettled with showery rain or thunderstorms spreading up from the south-west. Cooler on the thermometer but it will be feeling close. Max 23°C Min 16°C
Outlook: With maximum temperatures now going below 25°C, the heatwave has ended. That said it looks set to remain warm and muggy at times with a risk of occasional thundery showers. Temperatures should stay in the early-20s and thankfully a little less warm at night. Some computer models suggests another heatwave towards the end of the month as heat wafts up from the south. It’s too early to say will it or won’t it, and more often than not, these plumes get shunted east.
