Heading into a Rainy Pattern
WASHINGTON (ABC7) —
While Wednesday was the most gray of the next few days, it is the beginning of a rainy pattern that sticks around through the weekend. Wednesday's cloudy skies and on and off showers can be blamed on our easterly, onshore breeze. This brings in moisture from the Atlantic Ocean and basically piles it up on this side of the Appalachian Mountains. As the wind direction changes to the southwest tonight, so does the reason for our rain, but it's not checking out of the forecast.
Thursday and Friday are going to be much warmer (think 80s!) and turn somewhat muggy as air from our southwest moves into the Mid-Atlantic. A weak disturbance Thursday could bring a few morning showers, followed by afternoon and evening thunderstorms. Not everyone will see rain, but I think enough moves through that it's worth keeping the umbrella handy. Friday's rain and a few thunderstorms are in response to a cold front moving through the DMV. Behind this front we will briefly dry out.
This sets us up for nicer weather Friday evening through Saturday morning, but unfortunately it is short lived. As we head into Saturday evening the next system heading our way brings quite a bit of rain with it. The wave of low pressure will be in Oklahoma on Friday night, but it rides along a frontal boundary bringing it just to our south. Most weather guidance indicates we'll see 1-2 inches of rain. We are behind for the year by 2.8", so this could really help with our "moderate drought," and cleanse some pollen out of the air!
For the weekend, the driest weather should be here early Saturday, then keep the rain gear handy! It looks like the heaviest rain will move through Saturday night and Sunday morning. Not a bad weekend to do some spring cleaning... inside.
