Eric Horst went on a little Twitter rant about the Harrisburg-area radar hole today. Here's what he said:
@MUweather
The Harrisburg "radar hole"...it's a real thing, especially with Arctic snow showers. This traffic camera (near zero visibility snow) at Harrisburg and the Radar view below are both from the same time! How can it be snowing so hard, but nothing on radar?
@MUweather
I've been talking about this for years...it's flaw in the placement of the radar sites, in that there's not radar coverage below 10,000' in the Capital city of PA. Imagine that! As a result, we can't see these shallow squalls (which are mostly occurring below the radar beam)....
@MUweather
...and in the warm season we can't see low-level rotation (i.e. tornadoes). It's a huge problem IMO, but it's never been addressed. Perhaps some State politicians can look into a fix? A local radar would improve forecasts and safety of citizens...and more!
