Sunny and Seasonal

The weather, currently.

We will end the week with more sunshine. A ridge of high pressure is building into the region and will lock in bright skies right through into the first half of the weekend. Mainly sunny and 16°C early Friday morning, with sunny conditions continuing for the day. The high 27°C. The wind will be light from the S 10-20km/h and the UV index will be 9 or very high.

Friday Night: Mainly clear with a low of 17°C.

For those heading to cottage country or doing some camping for the weekend, overall great conditions until Sunday. We will see some rain and possibly thunderstorms developing Sunday afternoon. Needless to say, much needed moisture with southern Ontario only receiving about 11% of normal precipitation so far this month. Have a safe and happy weekend!

What you need to know, currently.

As heat waves sweep across the globe, inland lake evaporation is increasing, according to a new NASA-funded study in Nature Communications. Researchers studied more than 1.42 million lakes around the planet and found that between 1985 and 2018, average annual evaporation had increased at a rate of 3.12 cubic kilometers per year.

This seems fairly obvious if you’ve been following the news of bodies emerging from ever-shrinking Lake Mead, but because lakes and oceans make the bottom of the hydrological cycle having accurate data on evaporation helps scientists to better predict future weather patterns and direct water resources.

“From a global perspective,” study author Gang Zhao told NASA, “the total reservoir evaporation can be larger than the combined use of domestic and industrial water...This suggests that reservoir evaporation is an indispensable factor in water management, especially in times of drought and global warming.”
