Roller Coaster Weekend Weather

The image (courtesy TropicalTidbits) above is from the latest (18Z) North American Model and is showing an interesting weekend set-up across the northern Mid-Atlantic states as a deep trough digs into the Washington Region and a coastal storm quickly forms just to our east.

St. Patrick’s Day:

  • We start out sunny in the morning with increasing clouds during the afternoon hours.  Expect overcast conditions for the drive home with some evening rain showers developing across the DC Metropolitan area.  At the onset of the precipitation, some sleet pellets or wet snow flakes may briefly mix in with the rain.



  • Scattered showers will re-develop during the late afternoon or evening hours as the next cold front passes through the area and area of low pressure rapidly develops off of the New Jersey coastline.  Some steadier showers may move in from the northeast during the overnight hours across the northern half of the DC Region with rain and or wet snow (no accumulation expected).



  • Morning rain or snow showers, especially across the Baltimore Area with windy conditions developing behind the departing system.  Temperatures will definitely be chilly with high temperatures ranging from 45 to 50 degrees. Winds will pick up out of the Northwest gusting to 30 mph at times.  The image below is from the latest European model showing light snow falling across northern Maryland with a mix across the Washington Metro Area on Saturday morning (time stamp is 8AM). 

Hope everyone has a fantastic St. Patrick’s Day!

  1. Tonight and Tomorrow is a weather man’s dream! Extremely Dynamic situation…. I am seeing the potential of some very heavy snow Sunday morning across a large portion of the Metro Area… too bad temperatures will be above freezing! Also some nasty storms look to develop this afternoon across north-central and central Virginia with HAIL.

  2. Wouldn’t it be great if something actually ended up being a snowy surprise rather than a disppointment?. There does seem to be some trend in the models to develop the coastal storm further south with time.

    Then the warm frontal event tomorrow night, maybe get a surprise burst from that?
