Warmest weekend of the year is here

Weather Blog

PORTLAND, Ore. (KOIN) — It’s a mostly no-jacket kind of morning with the sun rushing in and the feeling of summer. Most areas will wake up to temps in the upper 40’s to low 50’s, above normal for mid April.

Easterly winds increase by midday but only for a few hours and not as strong as Friday. While there is no red flag warning at the time of this posting, an advisory, watch or warning may be issued by the National Weather Service at any time. Our dew point and relative humidity values will be low today and temperatures will be warmer. Highs for today will range from the low to mid 80’s, yeah, kinda like July. If the temperature at PDX exceeds 81, then a record will be broken.

Now – I bet you have a lot of yard work planned. Just remember burn bans are in effect for multiple counties until our weather gets cooler with rain in sight. And one more thing…. rivers and lakes are not at summer swimming temperatures yet. Think upper 40’s to low 50’s. Also, rivers will be flowing higher than normal thanks to anticipated snow melt.
