Oldies But Goodies
We are drowning in technology; a proliferation of apps, scripts, sensors, data in the cloud - good luck trying to keep up. All this tech gives the illusion of control, when in fact we have precious little.
With weather there's a perception that web sites, apps and local media will save you when skies turn threatening. "Hey, I can wait until the last moment, then make a mad dash!" Don't push the weather, especially when skies turn severe.
The old ways are still the best ways. Very large hail is a often a tip-off that a thunderstorm updraft is strong enough to spin up a tornado. Frequent lightning often means a severe storm is approaching. Weather approaching from the east is trouble. And if you hear thunder head inside right away - don't wait until you see lightning. People have been struck dead with blue sky overhead, the storm 10 miles away.
Minnesota will teeter on the northern edge of baking heat in the coming weeks. 90s stay south, but a few 80s are likely; dew points high enough to fuel a few severe T-storms Friday. The best chance of weekend thunder: Saturday morning and Sunday evening.
Warm enough for a dip in the lake, but nothing too sweaty brewing anytime soon.
Summary: Bill is no longer a tropical storm, but the threat posed by Bill is far from over. Although winds will gradually subside, along with the risk of isolated tornadoes in Bill's spiral bands, the prospect of torrential rain lingers in a long arc from Dallas and Oklahoma City into the Ohio Valley in the coming days. It's impossible to determine with precision where the most extreme rainfall amounts will set up, but conditions are ripe for more urban and river flooding as the tropical remains of Bill continue to pinwheel across the USA.
