Saturday Severe Risk. There's a slight risk of isolated severe storms from Wichita Falls, Texas to Altus, Oklahoma, another area where storms may exceed severe levels from near St. Louis to Evansville and Louisville. Details from SPC.
"...it implies that the water cycle could quicken by as much as 20 percent later in this century as the planet warms, potentially leading to more droughts and floods." - from a New York Times story, details below.
- To begin preparing, you should build an emergency kit and make a family communications plan.
- Listen to NOAA Weather Radio or to commercial radio or television newscasts for the latest information. In any emergency, always listen to the instructions given by local emergency management officials.
- Be alert to changing weather conditions. Look for approaching storms.
- Look for the following danger signs:
- Dark, often greenish sky
- Large hail
- A large, dark, low-lying cloud (particularly if rotating)
- Loud roar, similar to a freight train.
- If you see approaching storms or any of the danger signs, be prepared to take shelter immediately.
"A flash flood of hail? Is this for real?"
Friday Pics. Thanks to Tracy Corris, who sent in a photo from Santa Monica, California (upper left - obviously). Joan Kruhoeffer sent me the photo of mamma duck and her babies from Manheim, Pennsylvania. I appreciate everyone who takes the time to send in photos, YouTube clips, tweets and FB posts.
Go Ahead and Exhale
"Snow on April 28? After the warmest March in Minnesota history? You 'gotta be kidding me!" Deep breaths. This morning may test your meteorological sense of humor; character-building weather indeed. Models are hinting at a enough warm air in the lowest mile of the atmosphere for mainly rain, a cold rain at that. A few wet snowflakes may mix in - but I don't expect any accumulation. Whew. The sun is as high in the sky as it was in mid-August; even if it did snow it wouldn't stick around for long. Enough of the sun's invisible infrared radiation will penetrate thick, stubborn clouds to keep roads wet, even with temperatures close to freezing around daybreak.
We shouldn't be too shocked. The rolling 30-year average shows an average of 3 inches of snow in April. This is the last time I hope to use the s-word until October, OK?
A raw, rainy Saturday gives way to a 60-degree Sunday; a string of 70s next week. Tropical, 80-degree air over Iowa will set up a frontal boundary almost directly overhead, sparking a few waves of heavy showers and T-storms Tuesday into Thursday. More beneficial rains are likely. I'm feeling a little bit better about our long-term drought.
Yes, we still have Crazy Weather Boasting Rights for the USA: slush on a Saturday, temperatures near 80F. a mere 4 days later?
Lately the (warm weather) switch either is "on" or "off"!

"Warming Holes" Delayed Global Warming in Some Regions US Regions. Redorbit.com has the details: "Certain areas of the United States were spared the effects of climate change thanks to the presence of tiny particles in the atmosphere, suggests new research from climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS). Lead author Eric Leibensperger, a graduate student in applied physics at SEAS at the time of the study, and principal investigator Daniel Jacob, a professor of atmospheric chemistry and environmental engineering at SEAS and a professor of earth and planetary sciences at Harvard, used a 50 year model to study the effect of particulate pollution on regions in the eastern US, the school said in a Thursday press release."
