Nice Weekend Another Warm Up Then Jet Stream Flips Colder

Nice Weekend Another Warm Up Then Jet Stream Flips Colder

Screen Shot 2016-03-11 at 6.26.13 AMMarch 11- A cold front is moving through with clouds and a shift of winds today. That guarantees that temperatures will NOT hit 80°F again, but Baltimore was already 70°F at 2 AM. That will be today’s official high, but with sunshine this afternoon most of us stay in the 60s.  This weekend will be a little cooler, but more realistic with 60s. The dry weather should extend through Sunday making for prime conditions for area races and St. Patrick’s ‘Day’ events.  There is a split in the models as to whether rain will develop Sunday afternoon or hold off until Sunday night. So that is the wild card. I have to lean towards the dry GFS Model, but below is a comparison with the wetter NAM Model.

Reminder that we change the clocks forward 1 hour Saturday night, so Daylight Saving Time will allow you to enjoy the nice weather later into the evening.  Below is a look at the rain that will arrive Sunday night into Monday. Also see the slider showing the jet stream flipping back to a cold pattern after next week. It’s still March.. There have been recorded months warmer that this and just about any kind of weather is possible as I showed in my last report.

Wet or Dry Sunday?

Rain after the weekend?  The NAM/WRF shows moderate rain developing mid day Sunday around Baltimore but the GFS  looks like the chance for Sunday showers will be mostly north in central PA and the western Maryland mountains. That keeps Baltimore dry. The likelihood of rain increases at night. This is the wild card… and I will have a more firm view in my post later today….

Warming up again, then colder




Temperature Outlook

As I showed this past week, often our warm ups verify warmer, but the cool down that follows could be even colder… and lasts beyond this view
