We do not feel these cloud lines will grow upscale into deep congestus, given the prominence of dry and stable air in the lowest levels of the atmosphere (see 12Z KKEY SFC through 700 mb).
Today Through Wednesday Night A rather typical summer pattern is expected through the period as large-scale quasi-zonal flow gradually yields to a building upper ridge by mid-week. Weak upper troughiness ahead of the building upper ridge may support broader convective coverage on Wednesday as well.
Temperatures will be slightly warmer compared to yesterday as the upper level flow pattern becomes more southwesterly. The southwesterly flow persists into Wednesday as a low pressure system slowly makes its way into the Pacific Northwest, so another round of convection is expected Wednesday afternoon.
