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.

Hard to assess but extreme cold to northeast is from departed low and extreme cold from nw/w is from arctic high Expand 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. Link to comment Share on other sites More sharing options...

Roger Smith Posted January 19, 2019 Share Posted January 19, 2019 Best chances for thunder probably around 8 p.m. to 2 a.m. ahead of the low center which will be close to FDK around 0400h.
