Some of these stations are doing 18Z soundings. That’s not as helpful for morning forecasts

Moreover, the World Meteorological Organization encourages 12Z soundings; that data is shared via the Global Observing System (GOS) under the World Weather Watch (WWW).

The lack of morning weather balloons launched across the western and central U.S. is having a real, tangible impact on degrading forecast quality.

We can't look at weather balloon data that doesn't exist. We can't pump nonexistent data into models. We can't rely as heavily on models that don't "know" what's happening above our heads.

Today's severe weather forecast is less certain because we don't have weather balloon data to confirm the strength of jet stream winds aloft.

This is extremely frustrating, and is the result of logistical, organizational, political and budgetary decisions.

June 3, 1980:

A cyclic supercell spawned a family of seven tornadoes in Grand Island, Nebraska. Four of the tornadoes were significant (F2+). The circulations moved on complex and winding paths, and three of the twsters were anticyclonic. Five people were killed.

There’s a certain feeling of incredible awe I get while chasing that’s difficult to truly capture! This edit partially does it justice, but nothing will truly capture it. You just have to be there.
