Locally heavy rain likely this afternoon and tonight.
If storms train over the same areas then a few spots will pick up more than two inches of rain.
Heavy could could cause some brief flash flooding issues.

Here is the latest WPC/NOAA rainfall outlook.
Keep in mind, this graphic won’t capture those locally heavy thunderstorms that we often have during the summer months. Those storms can easily drop an inch or more of rain in less than an hour.
Here is the 72-hour rainfall forecast through 7 AM Saturday
Here is the seven-day rainfall forecast through 7 AM Wednesday
A fairly large rain event over the coming days. Some areas will likely top three inches of rain. This is much needed rain for many areas.
This is one of the larger/widespread rain events over the last few months.
Let’s zoom in a bit
KEEP IN MIND, this is broad-brushed by the WPC/NOAA
This is the seven day rainfall outlook.
Let’s hope some of this verifies.
Click to enlarge this graphic.
This is Missouri and Illinois centered
Kentucky and Tennessee centered
Spray conditions will be mixed. On and off shower and thunderstorm chances into at least Monday evening.
Locally heavy rain is likely from time to time.

The National Weather Service defines a severe thunderstorm as one that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.
Wednesday through Thursday: Thunderstorms are likely. Storms that form will produce gusty winds, lightning, and locally heavy rain. The threat of severe weather appears low to marginal. I can’t rule out a few reports of wind gusts between 50 and 60 mph. Isolated down-burst winds can occur with summer thunderstorms.
Friday through Monday: Thunderstorms are possible. Storms that form will produce gusty winds, lightning, and locally heavy rain. The threat of severe weather appears low to marginal. I can’t rule out a few reports of wind gusts between 50 and 60 mph. Isolated down-burst winds can occur with summer thunderstorms.
Locally heavy rain is a concern over the coming days. Avoid flooded roadways.
Summer thunderstorms can produce isolated microbursts.
microburst winds can exceed 50 mph.
What are microbursts?

Here is the preliminary fall outlook from the long range meteorology team.
Click to enlarge this graphic.
Our much needed rain has arrived. More is on the way.
Radar, early this morning, was showing quite a bit of activity over portions of the region.
Here is the 8:30 AM radar (screen grab)
You can see the heavier rain embedded in the shield of precipitation. Those are some gusty thunderstorms.
Some of you received heavy rain Tuesday and Tuesday night. Many areas did not receive rain.
I received around 0.60″ of rain at the Weather Observatory in northern Massac County, Illinois. Much needed rain.
Those who have not received rain will certainly receive some over the coming days.
Radar this morning shows widespread precipitation over southeast Missouri and southern Illinois. That is where the greatest coverage will occur today.
There will be chances across the rest of the region, as well. Those in need of rain will just need to be patient. It is coming.
Here is the NAM model’s future-cast radar. What it believes radar might look like into tomorrow. It won’t be exact. Just take the general idea from the animation.
It is struggling a bit with Thursday’s activity. We will have to see about the Thursday coverage.
There will be at least scattered showers and thunderstorms into Friday.
Time stamp is located in the upper left corner of the animation.
Click to enlarge.
Between now and Monday night, many areas will pick up an inch or two of rain. Some areas will top three inches of rain.
If thunderstorms train over the same areas then the odds of those three inch+ totals will increase. Training is where storms move repeatedly over the same county.
Let’s look at a few models.
This is the NAM’s rainfall forecast
This is through 1 PM Friday.
Click to enlarge the images.
This is the lower resolution NAM model’s rainfall forecast through 1 PM Saturday
This is the GFS model’s rainfall forecast
This is the Canadian model’s rainfall forecast
Notice that all of the models are painting quite a bit of rain over the region. That shows high confidence in the overall forecast. We should all walk away from this with decent rain totals between now and Monday.
There will be a chance of at least a few strong thunderstorms, as well. The overall risk of severe weather is rather limited. Cloud cover will help keep CAPE levels in check today over most of the area. CAPE is a measure of instability.
CAPE numbers could be higher on Thursday. We will need to monitor to see if a few intense thunderstorms bubble up Thursday afternoon.
There will be plenty of moisture for thunderstorms to work with. That means locally heavy rain is again on the table.
PWAT values will range from 1.7 to 2.1″ over the coming days. PWAT is a measure of moisture that thunderstorms tap into. Showers and thunderstorms will be prolific rain producers. Tropical-like.
Here is the PWAT animation map from the NAM model guidance. You can see the high numbers moving across our region over the coming days.
This prolonged period of high PWAT values is another indicator that heavy rain will be possible.
Time stamp is located in the upper left portion of the animation.
Click to enlarge.
There will be another wave of low pressure move across the region Friday afternoon and night. This will again increase rain coverage. There will be another one Monday/Monday night.
Both of those time frames is when we should see an increase in shower and thunderstorm activity. Locally heavy rain possible.
Here is the GFS model future-cast precipitation forecast.
This is one of many models.
The GFS is a lower resolution model. It has a tendency to make the rain coverage look greater than it is.
What I want you to take away from this animation is that we will see increased coverage of showers and thunderstorms both Friday and again on Monday.

It does appear that temperatures will be below normal over the next 8 to 14 days.
Here is the latest 6 to 10 and 8 to 14 day temperature outlooks.
The blue shading represents the probability of below normal temperatures. It does not represent actual temperature departures.
