Here is your very last chance to answer my weekly weather quiz question. This week’s question shouldn’t be too hard. What name is given precipitation that falls from a cloud, but evaporates before it reaches the ground? It is seen as dark streaks coming out of the cloud. Please post your answer as a comment after these forecasts. The first person to post the correct answer will win one week of free personalized weather forecasts tailored to your needs. Good luck. I’ll let you know the correct answer in my next post Saturday morning.

An upper level low is moving slowly to the South East (see the blue arrows in the gray “U” shape off the North Washington coast). It will push a weak frontal system ,that is just offshore, to the North and East with the strongest portion North of us and the weaker part dissolving as it moves through. That means we will see hardly and precipitation and quickly return to sunshine and much warmer temperatures. The high pressure ridge that is offshore West of the low (see how the blue arrows form an arch) will be bringing back the dry weather. The next storm system will move in between Monday and Tuesday.
