Looking for Rain

This week will start out mild, with a 'Vancouver Clipper' ushering in clouds & showers over the far NW corner of the PNW later tonight and Tue.  For those that enjoy rather warm afternoons, that will be the state of the weather later this week, esp over western OR & SW WA.  Temperatures will begin to warm up on Thu, then tease out in the upper 80s to low 90s Fri, Sat and possibly Sunday, Sept 15-17.   An onshore flow will cool down the region later on Sunday, to set up the following week’s wx pattern.

Monday Sept 18 - Fri, Sept 22 is trending very similar to this week, with a weak front passing over Vancouver Island with clouds/showers on Sunday the 17th, then a short period of warmer temps near the end of the week, as the onshore flow weakens.  Some model runs suggest a closed Low developing off the northern CA coast on Fri, which often leads to thunderstorms along the Cascades that can drift over the Willamette Valley.  We’ll see.  

The main “change”, if the models are correct, is for a rainy 24-36 hrs to arrive during the weekend of Sept 23,24.  Not every model run presents this solution, but it has charted several times over the past week, hence our report.  Should this change verify, we can expect the first WET weekend of the fall, with notable rainfall from BC down to northern CA.  The other model scenarios chart continued dry conditions and mild temperatures.  Which way will it go?

🌀 Hurricane LEE is likely to strengthen again and may take an unfavorable turn toward Cape Cod area - then turn north, skirting the NE Atlantic coast.  Yikes.  This storm will cause serious beach erosion, etc along the eastern seaboard. Another Atlantic hurricane is likely to follow LEE’s path, but it could make landfall a bit farther south (!) - this hurricane will be named NIGER.  Stay tuned.
