The eastern half of Kansas, including Hutchinson, is in a slight risk area for severe weather for Thursday. The activity will be along a weakening cold front and should occur primarily in the

Today it looks like the predictions are a little farther north of Wichita and a little shorter. Most are under 20 miles out. It looks like the winds above ~60K feet are pulling the balloons back to

There is a chance for isolated severe thunderstorms Thursday evening in central Kansas including Hutchinson, mostly a wind/hail threat. Nothing too unusual for this time of year. There are

All, Unfortunately we couldn't scramble the payload together in time for GPSL. Michael, Chris and I have prepared a secondary payload of just a simple crossband repeater using a DJ-580T. The backup

I'm going to be conducting a round table discussion regarding preparations for August's eclipse. Lat/Lon coordinates of launch site, if your group plans on flying during the eclipse. Do you intend

I will start running the predictions for GPSL again. As last year I will run 6 "corner" cases. The 3 Altitudes I will use is 60K, 90K, and 105K feet burst each with an ascent/descent rate of 850fpm

It seems the idea of pushing a strong cold front through the area next Friday has pretty well gone away. There will be a relatively weak front to the south, but temps north of the front will be near

GPSL Aeronauts, Please look over Joe’s request below and push some information his way that might help him. Joe, Quite a bit of what you are asking for is on the ARHAB.org web site but maybe a bit
