By Wednesday and Thursday, lightweight and breathable clothing will be more comfortable as temperatures approach 30°C. Bring a hat, sunglasses and sunscreen because UV levels will be high. A light rain jacket should remain close at hand, particularly in Sandy Lake today and across the northern communities as shower chances increase.
Anyone working outdoors should carry drinking water and plan regular breaks during the warmest part of Wednesday and Thursday.
