WASHINGTON — The scenario for the new workweek is a bit like last week, inasmuch as there will be some temperature swings. But it also looks like a quiet week, with no big storms and a lot of uneventful weather.
High pressure that pushed Sunday’s strong cold front through will now be giving us cool, northerly winds all day Monday, making it feel much more like it’s Halloween. The center of the high will wedge its way down the eastern seaboard, keeping us mainly dry except for a slight chance of drizzle Tuesday on easterly flow off the ocean and the bay.
Ultimately, the high will set up a broad southwesterly wind flow when the high’s center shifts to our south and east, just off the coast. This will give us another big warmup in the middle of the week.
Repetitive storms will be slamming into the Pacific Northwest bringing lots of rain and mountain snow. Some of that energy will swing a cold front our way near the end of the week but only with a chance for light showers. At this point, it’s uncertain how quick the front will be, and that will be crucial because it either means a very warm or a typically cool autumn Thursday.
Unlike last week, the cooler weather behind the front will stick around for several days in a row as the pattern becomes blocked over the north Atlantic. Once again, unfortunately, in this weather pattern there are no big rainmaking storms heading our way and our rainfall deficit will continue to grow.
