PORTLAND, Ore. — Portland is forecasted to see a mini heat wave of sorts with three days of unexpected 70 degree temperatures starting Monday, with Tuesday expected to be the warmest day of the year so far.

While the start of spring in the region started off a little rainy, these next few days will give a welcome break from colder temperatures and right on time for those out on spring break. There are thunderstorms forecasted on Wednesday, the last 70-degree day before another cold front arrives. 

Temperatures on Monday are expected to linger around 70 degrees with sunshine breaking through the clouds in the afternoon. Tuesday, however, will be the real treat for this time of year with highs in the Portland area forecasted to hit a record temperature of 77 degrees or warmer, according KGW Meteorologist Rod Hill. 

This unusually warm weather lines up with another time of year in Portland: blooming cherry blossoms. Some trees around the metro have been exploding with pink and white flowers, including the iconic cherry trees at Portland’s Tom McCall Waterfront Park. 

This warm burst of weather is expected to end with a boom, as thunderstorms and heavy showers are forecasted for Wednesday afternoon. 

Hill said there’s a good chance for thunderstorm activity through Wednesday evening as a cold front comes in overnight. Due to this, KGW has issued a Weather Impact Alert for that afternoon as it could impact some people’s plans.

After Wednesday, weather returns to rain and 50 degree temperatures.
