Seattle's Tuesday Discussion

It will be a wet start to the forecast period with dry weather ahead. The 6Z to 6Z period starts off with a warm front just moving through the area with a good amount of precip falling with this feature. The associated cold front isn't far behind, though, and will moving through from the northwest by 18Z. This will dry the area out with a upper ridge and surface high pressure building into the area by 6Z Wednesday. Models show good warm advection with heights rising and southwesterly flow turning to northwesterly behind the cold the front. The clouds and rain will keep temperatures similar to Monday's and the low could happen towards the end of the forecast period behind the cold front in a northerly flow.
