2.72" rain fell at MSP International yesterday, a new daily record for July 13. 3-6" amounts were reported over the western and southern suburbs.
The toughest challenges in meteorology? Whether a rotating T-storm will go on to tornado, will a hurricane get stronger or weaker with time, how many inches of snow for my yard, and WHAT TIME will that T-storm reach my house?
It was a simple question from one of our clients, Lifetime Fitness. "Will there be lightning for the Saturday morning triathlon?" We know when the atmosphere is ripe for T-storms, but they're usually too small to show up on computer models. A new generation of high-res NOAA models going out 15 hours offers more skill, but most days we still can't determine, with any consistent skill, whether T-storms will produce severe flooding more than 1-3 hours in advance.
Saturday's warm frontal squall dumped over 4 inches on the southwest suburbs; about 5 week's worth of rain in 5 hours.
More T-storms pop today; enough hazy sun trickling thru the murk for upper 80s. I expect 4 days above 90F in a row this week - tomorrow into Thursday. The Dog Days.
I estimate at least 900 square miles of southwest suburbs picked up 4" rain Saturday. That works out to 62 billion gallons of water, or 1.5 billion bathtubs full of water. Some watery perspective.

I took out my phone and took some videos and wow, were the flashes really bright. I was able to screen grab a few of the lightning bolts, like this one. There were over a 1000 reported lightning strikes at one point from this cluster of storms. The booms of thunder were so loud at one point, my car shook! And in the studios, once I got to work, you could hear the boom of thunder very clearly through the walls..."

Red outlines indicate hot spots where MODIS detected unusually warm surface temperatures associated with fire. The Eastmain fire, which became the 2nd largest fire since 1959 in Canada at 1.6 million acres, is at the upper left of the image, just east of James Bay. Other fires near Nemiscau, Quebec (about 150 - 200 km to the southeast of Eastmain) are also burning, but these patches are "only" 120,000 - 200,000 acres. MODIS also observed smoke from the fires moving across the Atlantic Ocean on July 5, July 6, and July 7. By July 8, smoke was drifting over Scandinavia." Image credit: NASA.

There is a deep animus to anything related to climate research on the side of the majority… But the fact is, climate impacts weather. Our experts need to have full knowledge and expertise about this impact so there can be better forecasting.This logic failed to resonate with Republicans, as Vice Chairman Jim Bridenstine (R-OK) explained his opinion that NOAA is spending too much money on “ineffective research on climate,” and suggested weather forecasting should be a higher priority than climate change research..."
