Weather advice:
As we prepare for spring, let’s make sure you have three to five ways of receiving your severe weather information.

Forecast Discussion
No weather concerns today.
Well, calm weather has settled into the region.
The weatherman is going to have a bit of a break.
We have a seven day forecast with no severe weather in it. That is quite amazing for late May. It is peak tornado season!
Many areas have received quite a bit of rain over the past sixty days. But, some of us still need rain and have been missed by the higher totals.
I have only received less than 1.50″ of rain at The Weather Observatory in Massac County. That is for the Month of May.
Typically, we have more than that. It is a bit on the dry side. There are some other locations that have been missed lately, as well.
Here is the past seven days (through 7 AM Saturday). Rainfall totals.
You can see those lower totals over extreme southern Illinois and portions of Missouri and Kentucky. Other areas have received many inches of rain during the same time period. Portions of western Kentucky received two to four+ inches of rain from the event a couple of days ago.
The past thirty days.
Here is the 30 day precipitation anomaly. Many areas are below average.
There will be a slight chance of a few showers and thunderstorms Tuesday and Wednesday. In the 10% to 20% range. Most of the area will remain dry and it is possible those storms won’t form at all.
There will be a very weak amount of lift in the atmosphere during those two days.
Otherwise, nice weather into next weekend.
I continue to watch a large upper level low over the East Coast next weekend into the following week. For now, that is forecast to remain to our east and southeast.
If it were to move closer to our region, then we would have more clouds, cooler weather, and even some showers.
For now, that is not the forecast. I will, however, keep an eye on it.
NOAA has released the July through September precipitation outlook. They have out region in above average precipitation.

This outlook covers southeast Missouri, southern Illinois, western Kentucky, and far northwest Tennessee.
Today through April 18th: A couple of the Saturday afternoon and night thunderstorms could produce damaging wind and hail. The tornado risk is low, but not zero. Mainly over Missouri for the tornado risk. The line will weaken with time as it moves farther east.
.
Today’s Storm Prediction Center’s Severe Weather Outlook
Light green is where thunderstorms may occur but should be below severe levels.
Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.
One is the lowest risk. Five is the highest risk.
A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
