- A break from the recent rainy pattern still looks on track for the second half of the week but some isolated showers cannot be ruled out. There are indications another rainy pattern may return early to mid next week influenced by tropical moisture.
- The cooler than normal trend, especially with daytime temperatures, will continue with some moderation by the weekend.
