FAQ
Reader questions
Why does the radar sometimes show no echo over Oskaloosa even when it is raining?
Gentle stratiform rain or cells just outside the beam may appear weak or absent, especially with distant radar angles.
Can I use free apps to track supercells approaching from the west?
Yes, many reliable apps pull the same NEXRAD data and can show velocity and storm relative hodographs for severe cells.
What time of day do severe storms most often develop near Oskaloosa in spring?
Late afternoon and early evening are most common as daytime heating and wind shear align, which radar trends can help anticipate.
Is it safe to drive toward a storm cell shown moving toward the city limits on radar?
Avoid traveling into the core of strong storms, as wind shear, hail, and sudden downpours can quickly create hazardous conditions.
