Portland wakes up under a gray blanket this morning, with temperatures in the low 50s and a high near 67°F expected today, June 7. Skies should stay mostly cloudy through the afternoon with a light southwest breeze. It is a brief dry window, since wetter weather is already queued up for early next week.
Afternoon Into Tonight
This afternoon stays mostly cloudy with highs topping out around 67°F and gentle southwest winds of about 3 mph. Tonight, temperatures slip back to around 51°F. After about 4 a.m. Monday, rain chances climb, and early-morning showers could drop roughly a tenth to a quarter of an inch in some spots.
Rain Returns Monday
Rain is likely on Monday, June 8, with a high near 60°F and steady rain for much of the day. By the time showers break into more on-and-off periods Monday night, totals could reach about a quarter to a half-inch. A few isolated, brief thunderstorms are on the table Tuesday afternoon, although they are expected to stay below severe levels. Small Craft Advisories are up for parts of the coastal waters Monday, with more detail available in the forecast from the National Weather Service Portland.
Looking Ahead
Later in the week, high pressure starts to build and temperatures head upward. Ensemble guidance points to a sharp warm-up from June 11 through 15, with inland highs possibly getting close to 90°F by Saturday, June 13. This pattern first showed up in our June 5 preview.
What To Do
For Monday, plan on packing an umbrella and leaving a little early, since steady rain can slow both roads and transit. Mariners should respect the Small Craft Advisories and steer clear of exposed routes Monday morning. If you are sensitive to heat, this is a good time to sort out your game plan for next weekend, when inland neighborhoods could be dealing with hot afternoons and warmer nights.
