Using GOES-16 to Detect and Forecast Cold Temperatures

Just where was the coldest spot in New York state this morning? With weather stations, you could get close, but with the new GOES-16 satellite, you can find the exact spot. Just southeast of Philadelphia NY. The bright green in northern New York is a ground temp. of 234K which is around -39 C. Philadelphia NY, in that area had a low of -39.5C.

Rare Cloud Display Across Ohio and Indiana Thursday

You see those strange holes in the clouds across Indiana and Ohio? These are fallstreak holes or “hole punch” clouds, and they happen when aircraft fly through clouds of supercooled water. These clouds are well below 0° C, but the cloud droplets are still liquid (water will not always freeze into crystals of ice until the temperature reaches about -40° F/-40° C). If a few ice crystals are introduced, then a rapid …

Consensus Matters- The Research Says So!

Those of us in science communication can be forgiven for thinking that everyone knows that agreement among scientists on climate change is extremely high. (It’s around 97-99% and the 1-3% who disagree have substantially less experience/publications in the field than the consensus group.) The Hard Truth The hard reality though is that most Americans have no idea the consensus is that strong and it makes one think that if we could …

Delaware Quake May be Africa’s “Fault”

This is one of those days that illustrate why broadcast meteorologists must learn all of the Earth science they can. An earthquake struck 10 km east of Dover, Delaware at 4:47 PM EST this Thursday evening. The epicentre was in the Prime Bombay Hook National Wildlife Refuge (A fantastic place to see all kind of birds), and was felt as far north as NY state! It looks likely to equal the largest …
