Discussion
A cold front will pass through the region tonight and then a fast-moving, but potent little system will ride along the front on Wednesday. This system will spread some precipitation into the region and odds favor snow in the northern and western suburbs of the District, but rain can be mixed in at times for awhile from the District and points to the south and east. Accumulations from a coating to 2 inches are possible by early evening with the higher amounts in the northern suburbs (e.g. Montgomery and Howard Counties) and the lesser amounts to the south and east of the District. Looking ahead, last week we talked about a strong high pressure ridge that would develop across western North America and help to bring some of that bottled-up western Canadian cold air towards the eastern US. The first cold blast from this new pattern will occur this weekend following Friday night’s cold frontal passage and temperatures will likely struggle to reach 40 degrees on both weekend days.
