Current surface pressures . Actually current obs look weaker and a little south of the nams at this current hour .Nams are around 994-95 mb and centered on the Kentucky/ TN line if not a lil north of that

That’s 1pm and that 998 did not lift from the 12noon one so will be interesting to see 2pm one

It was 37 when I got up and I live in southern part of Harford County.   As soon as I saw that, I knew this one was a done deal.  

Not necessarily ...

grab your cell phone ...

purchase a sling psychrometer ...

have it delivered by a drone ... 

open the package ...

read the directions ...

take it outside ...

measure the wet bulb temperature ...

estimate the RH from the wet bulb temperature using https://www.sailangle.com/articles/details/id/10  ...

Go to http://www.sciencebits.com/SnowProbCalc?calc=yes ; plug in the RH and T

Estimate your chances

Thanks for the 2nd link...that's pretty cool.  Unfortunately, the odds of me seeing any snow are slim to none.  The only thing I'm hoping for at this point is that they overestimated how much precipitation will ultimately fall for northern MD, that we'll come in under an inch and that we might see some wrap around snow showers tomorrow with the advancement of the Arctic front.

-2.5 850 And -1 925.

surface plots shows a 998 that surface plot wise did not gain latitude in last hour but rather due east. Hard to assess but extreme cold to northeast is from departed  low and extreme cold from nw/w is from arctic high 

Yeah, I agree, Howard.  Some surprises in store for us.  I posted the 2 hour pressure change map.  We have a lot of warm air advection at 850 mb and the 850 mb low may pass over most of us.

Surprises? Can’t disagree more. There’s been nothing but a warmer trend and delay in precip today. NWS even had to scale back advisories and warnings
