Currently in Boston— April 6th 2022
The weather, currently.
If you didn't get a chance to enjoy some of the sunshine today unfortunately it's going to be a few more days before the weather turns nice again. Low pressure will pass south of New England on Wednesday bringing rain especially to the Mass Pike and points South. It will be raw and damp with temperature staying in the mid 40s all day. They'll be some drizzle or a few light showers Wednesday night and Thursday but not much in the way of accumulating rain. Thursday evening another area of low pressure brings some heavier downpours which will last into early Friday before partial clearing develops to start the weekend. —Dave Epstein
What you need to know, currently.
There is something sweetly antiquated about weather balloons. Charming and slightly spooky, they seem like the kind of technology that should’ve gone the way of the typewriter or the steam engine, but meteorologists have found that they are still among the best (and cheapest) ways of getting accurate weather data. Every day, twice a day, roughly 900 weather balloons are released around the world, carrying small devices called radiosondes that measure atmospheric conditions and transmit data back to the National Oceanic and Atmospheric Administration (NOAA) via radio signal.
Their flights usually last around two hours and balloons can rise up to 100,000 feet, sometimes traveling hundreds of miles from their launch sites. When they hit the upper atmosphere the balloon begins to fray, and the radiosonde descends to earth with a tiny parachute.
One might think this would result in injuries—radiosondes striking down unsuspecting bystanders like meteors—but they only weigh about four ounces, down from two pounds in the 1990’s. In 2015, the bomb squad was called to Northeast Philadelphia when a radiosonde landed on a car. There are also weather balloon enthusiasts who hunt them down with HAM radios, but, for the most part, the radiosondes are lost after they make their descent.
Last week, the National Weather Service (NWS) announced that it would be releasing fewer weather balloons due to global supply chain issues impacting their helium orders and contract issues with one of their hydrogen suppliers. As of today, the NWS announced that the contract issues have been resolved, but supply shipments of hydrogen could take up to six weeks to arrive. The helium shortage is ongoing. The nine affected sites, which range from Tallahassee, Florida to Buffalo, New York, will reduce balloon flights to once a day and do away completely with flights on days with good weather.
“Because of the vital importance of this data, we have been doing everything we can to resolve supply issues,” Susan Buchanan, a spokeswoman for the National Weather Service, told Currently.
While the National Weather Service claimed the disruption would not affect weather forecasting, scientists are skeptical.
“We can’t go back and get that data,” Sandra Yuter, a professor at North Carolina State University, told the New York Times. “We’re going to have big gaps.”—Rebecca McCarthy
