Get ready for a cool morning with temperatures below normal in the low to mid 30s! Showers are expected to taper off overnight, leading to a drier day around the Sound on Thursday. However, the chance of showers will return in the afternoon, with the foothills of the Cascades and areas south of the Olympic mountains most likely to receive rain.
A trough of low pressure overhead is keeping the showers mainly in the Cascades and east to Spokane, with temperatures expected to be below average in the upper 40s to near 50 on Thursday. A spinning area of low pressure within the trough will continue to bring showers to central and eastern Washington as it tracks towards California.
The snow level is low, around 2,500 feet, leading to mountain snow showers and minor accumulations of around 1 inch. Friday is forecasted to be the driest day, with warmer highs near the average of 57.
Looking ahead, a weak frontal system is expected to arrive for the weekend, bringing showers and sunbreaks each day. Saturday may even see an isolated thunderstorm in the afternoon, with cooler highs in the upper 40s to near 50. The weekend will continue with rain showers and sunbreaks until the showers track into the Cascades on Sunday evening.
A warming trend is on the horizon for the new week, with higher pressure building up from the south to bring temperatures near 60 by Tuesday. Wednesday is expected to be dry and warm, providing a welcome break from the wet weather. Stay tuned for updates from meteorologist Rebecca Stevenson and the KOMO 4-Cast Team.
