Overview
- Forecasts now show a change from dry, sunny conditions to rain and thunderstorms beginning Wednesday, with the highest chance of the heaviest, locally intense storms on Thursday evening.
- Temperatures climb into the mid-to-high 20s ahead of the storms, with Thursday expected to be the warmest day and some forecasts showing peaks around 28–29°C.
- Meteorologists warn the storms could bring short-duration heavy rainfall, thunder and strong gusts and note that impacts will vary a lot over short distances.
- Weather models suggest substantial totals in convective bands—commonly 20–35 mm in places with higher amounts locally—but forecasters stress timing and exact tracks remain uncertain and are being monitored.
- After the convective episode a cooler southwesterly flow is expected to arrive from Friday, producing lower temperatures and continued unsettled weather into the weekend, and the week sits within an unusually warm summer that may challenge regional records.
