Pretty standard summer fare in store for us this weekend. Highs in the low 90s, with a heat index approaching 100°. A few isolated showers and storms will be possible, but more of us miss out on rain through Sunday. The heat and humidity will make strenuous outdoor activity dangerous. If you need to do yardwork, try doing it before 10 am or after 6 pm.
The above chart shows wet bulb globe temperature (WBGT): a little better indicator of heat stress/danger than heat index.WBGT uses temperature, humidity, sunshine and wind to give you a better idea of when to work outside.
Nothing cool in the forecast
Typically, the hottest part of the year comes between now and mid-August. The heat building this weekend and next week is right on time.
This round of hot weather is not unprecedented, record-setting or even remarkable. It’s just the hottest we have dealt with this year so far.
A strong ridge to the west next week slowly gains more and more control of our weather. While it’s still to the west, there’s a decent chance of scattered storms on Monday and Tuesday; after that, more influence from that ridge means few if any storms and hotter days toward the end of next week.
