Weather Synopsis for Monday & Tuesday
A weak front will move through the area today, reinforcing cloud cover and spreading increased shower activity in the afternoon. A weak area of convergence over the San Juans and western Cascades of Skagit/Whatcom counties will fizzle out later today. However, after the frontal passage this afternoon, we'll see a stronger area of convergence take shape over the central Cascades, affecting the Mt Loop Hwy, Stevens Pass and Snoqualmie Pass areas overnight and through Tuesday morning. While this won't be the PSCZ of the year, we'll see some localized overnight snow totals in the 3-6" range above 3000' accompanied by moderate westerly ridgeline winds. Mt Hood will likely pick up similar amounts of snow as showers increase overnight along with even strong westerly ridgeline winds.
Showers will continue on Tuesday but become more scattered in the afternoon as upper level ridging builds offshore. We're likely to see more sunshine along the east slopes of the Cascades on Tuesday afternoon along with higher freezing levels versus the cloudier west slopes of the Cascades.
