Direct hit: Wet microburst bomb drops right on radar site

Here's a meteorological phenomenon you don't see often.

A monsoon-driven wet microburst dropped it's rainy payload right over the El Paso, Texas Doppler radar site Wednesday evening.

The resulting Doppler image looks like the shock wave from a meteorological bomb flowing outward from the epicenter of the microburst.

Though it has been used in the past, notice I didn't use the term "rain bomb" to describe this event. That's not really an accurate term, and some meteorologists correctly take issue with that description of monsoonal downbursts. I spent 9 years forecasting and warning for monsoonal thunderstorms in Tucson, Arizona. I know what dry and wet microbursts are.

But I did choose to describe the resulting Doppler loop in the tweet from the El Paso NWS as resembling a "shock wave from a meteorological bomb flowing outward" because that is an accurate description of what the Doppler looks like in my opinion. The 70+ mph gust front flows out radially from the center of the microburst like a shock wave from a bomb blast as it strikes the ground.

Then of course there's the irony of a microburst putting a direct hit on a Doppler radar site. Doppler Dog finally catches stormy car bumper?

Eastern Minnesota and Wisconsin have recorded plenty of rainfall in July. Much of southern Wisconsin has soaked up 5" to 10" of rain this month. But western Minnesota has trended dry.

Thirty-two percent of Minnesota is now in abnormally dry or moderate drought categories in this week's U.S. Drought Monitor.
