Snowfall Verification for Feb 10-11

What a strange storm this was… The three-part storm that I was expecting to be a two-parter. First, the snow in central MD over-performed Friday night as temperatures were just cool enough to allow snow to accumulate more quickly. The second part, the squall line, went as expected as accumulations of a dusting to a […]

Snow squall pushes through the Mid-Atlantic

A snow squall developed ahead of a cold front this afternoon, kicking up winds and bringing a short burst of heavy snow (and thundersnow). Here’s a video I took of the snow squall as it passed through Gaithersburg, MD: And here’s the radar for the squall:  

Winter Storm Threat: Feb 10-11 (only/final call)

Here’s my snow map for now through Sunday morning 7am:   Above normal boundary layer temperatures are going to hurt totals again for those east of the mountains. The main batch of precipitation will work through tonight and will start off as rain. It should change over to snow by the early morning hours in […]

Snowfall Verification for Feb 8

Another headache-inducing storm with poor rates, boundary layer issues and overdone QPF amounts: The verification wasn’t as bad as I thought it would be. I still got the general idea right, but was off in some key areas east of the mountains. The northern extent of 1+ inch accumulation in NJ was a bit surprising, […]

Winter Storm Threat: Feb 8 (final call)

Have to get this out now since I’ll be at work when the event starts!  

Winter Storm Threat: Feb 8 (first call)

One of the more promising events I’ve forecast this winter…   Plenty of cold air aloft, but surface temperatures look to hurt the initial snowfall accumulations before either the rates get high enough of the surface temperature cools to the freezing mark. Higher elevations stand a better chance of snow (both for surface temperatures and […]

Snowfall Verification for Feb 4-5

The verification on this one was rather interesting… some odd shapes/placements of the snow totals: The front-end of the system over-produced and the back edge under-produced, with some front-end banding boosting totals in central MD. Lighter rates and above-freezing temperatures kept the totals down elsewhere. Overall, I had the right idea, but with a warm […]
