A Memorable Storm System

Some in our region may be scratching their heads, wondering what the big deal is about this latest installment of Spring's bag of tricks.

Well, let's look at it from a larger perspective.

First, a warm frontal boundary set up Friday night/Saturday morning, producing an efficient amount of rainfall along either side of that boundary along with some severe weather. Some in our region were negatively impacted with some storm damage reports; however, heavy rain resulted in flash flooding and areal flooding (creeks, rivers overflowing their banks) as the warm front seemed to have difficulty moving northward. It was as if the front stalled for a time as waves of storms kept pounding the same areas over and over again.

Here is a look at some rainfall reports regionally and locally...from Friday night/Saturday morning...

Huntingburg, IN (Dubois County)......8.11"
Evansville, IN.......5.62"
LaGrange, KY.......4.85"
Westport, KY.......4.34"
Indianapolis, IN....2.51"
Cincinnati, OH....2.41"

Around Louisville....

Louisville Int'l (official)....1.20"

New Albany, IN.....5.05"
Transylvania Beach Pumping Station..4.58"
Galena, IN......3.85"
Park Lake, KY....3.54"
Jeffersonville, IN...3.33"
Springhurst, KY....3.28"

In addition to the heavy rainfall, there was a confirmed EF-1 tornado in Goshen, KY in Oldham County and hail up to the size of half-dollar coins in other locations.

On the other side of the cold front now approaching us from the west is a classic Spring 'winter storm'. Parts of Colorado, Wyoming, and now Kansas and Nebraska are dealing with blizzard conditions and heavy snowfall.

Check out some of these snowfall amounts....thru Saturday morning

Colorado City, CO......24.0"
Golden, CO......11.1"
Boulder, CO...8.0"
Keyes, OK...8.0"
Santa Fe, NM....7.0"
Amarillo, TX...3.0"

In Amarillo, just a week earlier, temperatures were flirting with 90 degrees again. Yes, shortly after the middle of the month, they already hit 90.

Snowfall is expected to continue into parts of the Plains. High winds coupled with the heavy snowfall may lead to power outages for some residents along with reduced visibilities and traffic headaches.

Locally, along this cold front, a shield of rain along with isolated severe storms are forecast. This may aggravate already saturated grounds for those that have already received several inches.
