So.. in 7 days it's going to either be snowing and 30 or sunny and 80. LR forecasting sure has come a long way lol

Spring is the worst with it. I’m ready to get to “highs in the upper 80s with a chance of afternoon storms, some may be strong to severe” on repeat.

        I know that this is somewhat tongue-in-cheek, but all 3 of those forecasts agree on a very cold air mass to our north and a very warm one to our south.    They simply disagree on the location of the boundary.      That's really not unusual in any way for a 7 day forecast in spring, even if the difference in sensible weather impacts is massive if you move from one side of the front to the other.    And the disagreement is less if one examines the ensembles.

It's just MD in spring lol. Hopefully the gfs has the right idea about active weather. A couple of cold rainers would be fine. I'd love an all day soaker that drops 2"+ area wide.

Big difference with the GFS and EURO/CMC on Saturday. Highs in the 40’s to highs in the 70/80s.

LONG TERM /THURSDAY THROUGH MONDAY/...
Warm front gradually lifting northward across the area Thursday
night through Friday night should result in an overall milder
trend, though passing low pressure may produce some rain,
especially across northern parts of the region and especially
Friday night. The warm advection should result in lows mostly
above freezing Thursday night, highs approaching or passing 60
in much of the area Friday, and lows remaining in the much
milder 40s to low 50s Friday night.

This front then starts to stall to our northeast, and passing
waves of low pressure along it may cause oscillations. The end
result is that while overall, the weekend looks mild, a
northeast to southwest temperature gradient is expected, with
areas closer to New York City more likely to struggle to reach
60 both days, while the central Delmarva could easily be well
into the 70s. Chances of rain will likewise be higher across the
north, with much less chance down in the Delmarva. Lows
Saturday night will also be mild, likely 40s north and 50s
south.

Stronger frontal system then likely crosses the region Sunday
night into Monday, with better shower coverage region-wide, but
also warmth becoming more widespread a southerly winds increase
just before frontal passage. This likely pushes lows into the
50s for much of the area Sunday night with most of the region
reaching the 60s Monday, with 70s more likely in the Delmarva.

NWS is giving the GFS nothing then in essence.
