WEATHER53 Posted March 30, 2022 Share Posted March 30, 2022 So DCA doing it 7-10 degree variance thing again and let’s discuss recent events. Two nights of very windy where variances were 1-3 degrees. So, the wind homogenizes the air and there is not a big difference. What that has to do with tonight is that without the wind DCA can’t homogenize and/or radiate correctly.. Best guess as to why is that there is an obstruction or hinderance of some form preventing DCA from doing what other observations are able to do.

Warm air must be moving in aloft because it's actually warmer here then there. I've noticed this since I've been here. Days where warmer air is moving in it's warmer here at higher elevation. One morning back in December it was 41 here but down the road in this little river valley it was frosty and 31. 1 Link to comment Share on other sites More sharing options...

That does happen, but also the trough is exiting stage right and the warmer air is right on the heels coming in from the west, so the cold is hanging on over here a tad longer. Wind completely died down here overnight with clear skies, so perfect for temps to drop and plenty of frost to form. 1 Link to comment Share on other sites More sharing options...

MN Transplant Posted March 30, 2022 Share Posted March 30, 2022 I don’t think I’ve seen it mentioned here, but Sterling is one of the upper-air sounding sites that have suspended regular launches to the lack of available hydrogen and helium. 2 Link to comment Share on other sites More sharing options...

There is a listserv that I'm on that has been discussing it, and they listed LWX as one of the locations. Sure enough, I went to the Wyoming sounding site and it was a no-go today.

MN Transplant Posted March 30, 2022 Share Posted March 30, 2022 More 000 NOUS41 KWBC 291820 PNSWSH Public Information Statement 22-17 National Weather Service Headquarters Silver Spring MD 220 PM EST Tue Mar 29 2022 To: Subscribers: -NOAA Weather Wire Service -Emergency Manager Weather Information Network -NOAAPORT Other NWS Partners And Employees From: Michelle Mainelli, Acting Director Office of Observations Subject: Changes in Weather Balloon Launch Frequency Effective March 29, 2022 Effective March 29 and until further notice, the National Weather Service is reducing the frequency of weather balloon launches at several upper air locations in the United States due to a global supply chain disruption of helium and a temporary issue with the contract of one hydrogen supplier. The National Weather Service launches weather balloons from 101 upper air sites throughout the United States and the Caribbean, using helium to inflate the balloons at 12 of these sites. The agency converted the remaining sites to hydrogen because it is cost effective and a more reliable gas option. Approximately 9% of the total upper air sites are currently affected by the gas shortage and temporary contract issue, including 5 of the 12 helium sites and 4 hydrogen sites. We anticipate that these issues will impact additional upper air sites. To ensure there is enough gas on-hand to launch balloons in support of forecasts during hazardous weather, the affected sites have either reduced launches to once per day or suspended flights during calm weather days. This temporary adjustment will not impact weather forecasts and warnings.The affected sites benefit from data collected by balloons launched from neighboring upper air sites. Be assured we will take all steps possible to mitigate the supply chain and contracting issues. Radiosondes are instruments attached to weather balloons that send back a wide range of upper atmospheric data to support weather forecasts, including temperature, dew point, relative humidity, barometric pressure, wind speed, wind direction. Radiosondes are one of many technologies that collect earth observation data for use in weather modeling and forecasting. Data is also collected from instruments aboard commercial aircraft, surface observing stations, satellites, radars, and buoys. The National Weather Service will continue converting sites to hydrogen where locations, leases and safe operations allow, and as funding becomes available. If you or your organization have any questions about these changes, please contact: Susan Buchanan Director of Public Affairs National Weather Service Phone: 202-834-5235 E-mail: [email protected] National Service Change Notices are online at: https://www.weather.gov/notification/ 1 Link to comment Share on other sites More sharing options...
