Portland hit 95 today, but that was one of the “cooler” metro area temps:
Salem hit 100 and you can check out the triple-digit heat east of the Cascades and in Southern Oregon!
It’s been a crazy June, the warmest we’ve seen since PDX became the official Portland observation site around 1940. It’s also likely the warmest we’ve seen since record-keeping began downtown just 10 years after the Civil War!
Some more records…today was the 6th day at/above 90 degrees here, which ties the June record. We’ll break it tomorrow.
Due to the very hot and extremely dry conditions, Multnomah County has taken the unprecedented step of banning all open flames…INCLUDING FIREWORKS until further notice. Luckily that’ll save me some money and it’ll be
Thunderstorms did develop as expected in the central/southern Cascades and they lasted long enough for one strike up around Detroit. They are done now but expect another round tomorrow afternoon/evening farther north. We MIGHT see some lightning to our east this time Saturday evening.
Still a chance for a thunderstorm through the day Sunday, then increasing onshore flow plus best dynamics shifting the action north and east mean we’re done with that threat.
Once we get past a scorcher tomorrow (slightly warmer with light wind), a good marine push plus lots of high/mid clouds Sunday means at least a 10 degree drop in high temps.
Temps stay reasonable Monday-Tuesday…in the mid-upper 80s, then a 2nd heat wave arrives Wednesday through the 4th of July.
How hot is “Round 2” going to be later next week? Morning models were real scorchers with easterly wind likely pushing temperatures to around 100 again over Independence Day weekend. 00z GFS not quite as crazy, but it’s pretty clear we have a 2nd heatwave as we head into the the 4th of July holiday weekend.
Stay cool this weekend!
