The forecast for severe or extreme weather risk for the next 48 hours...

Wednesday night: 
Severe weather is not anticipated at this time.  Some severe storms possible over the very far eastern counties - Louisville down towards Bowling Green.

.
Thursday: 
Severe weather is not anticipated at this time.

.
Thursday night:  
Severe weather is not anticipated at this time.

Friday: 
A few thunderstorms may approach severe levels - especially over the southern parts of southeast Missouri, northeast Arkansas, and west Tennessee.  Will update this part of the forecast as it becomes a bit more clear.


.

Lightning Safety week has arrived!  You can learn more about lightning safety by clicking here.
.

.
Here are the graphics for the coming days.  Remember the orange area represents the slight risk (that is what the Storm Prediction Center calls it - not my favorite choice of wording) area for severe thunderstorms.  The orange area means that severe thunderstorms will be possible but will most likely not produce widespread severe weather.  The yellow area represents that areas where some thunderstorms will likely occur - but will remain, for the most part, below severe limits.  A severe storms is one that produces winds of at least 58 mph and quarter size hail or larger.  And/or tornadoes.

.
Thursday's severe weather outlook graphic
.
.
Then here is the Friday outlook (below) - you can see we have some chance for severe thunderstorms on Friday - this will need to be updated and tweaked as it becomes a bit more clear as to how storms will evolve.  We may also have to watch the weekend for a few severe storms (again similar pattern to the recent week - scattered severe storms)

HEADLINE:   Well - thunderstorms held off, for the most part, on Wednesday.  I thought there would be a bit more activity than there was.  Storms formed a bit further east (a county or two) than I thought they would.  This left many areas dry and windy.  Temperatures were a bit more comfortable, as well.  

.
The next round of storm chances will arrive on Friday into Sunday.  It will not rain all the time.  But there could be several periods of rain.  The pattern will resemble the recent week where some places receive heavy downpours while neighboring counties receive very little in the way of precipitation.  Several thunderstorm complexes are expected to form over Missouri and slide into our counties.  I will monitor and tweak the forecast once it becomes a bit more clear as to where these storms will track.
.
Temperatures will average below normal to near normal into Saturday.
.
Check out this amazing satellite view of the powerful storm system that brought all the severe weather to the nation over the last few days.  Widespread wind damage was reported over central and northern Illinois yesterday - among other areas.  This is a visible satellite image of the wound up storm.  Click image for real size view.
.
 .
Here are the reports of severe weather from Tuesday - you can see widespread reports.  You can view details by choosing your own map and dates here on this link from the Weather Observatory web-site - click here
.
.
Here are the reports from Monday, as well - so you can see this storm system produced quite a bit of severe weather over the nation.
.
.
Significant to major flooding will continue on portions of the Mississippi River and Missouri River basins.  This will be a long summer of flooding for some areas.  We are also concerned that the Ohio River will continue to back up.  This could cause flooding over parts of southern IL and western KY.  Stay tuned.
.
You can listen to LIVE reports from Minot - click here

.
We have a TON of new weather maps on the Weather Observatory web-site - these include temperatures, wind speed, dew points, heat index, barometric pressure, predicted rainfall, climate forecast, medium and long range maps, forecasts and more!  Click here 


.
The McCracken County Office of Emergency Management reminds you that owning a NOAA Weather Radio is the best way to receive notifications of severe weather watches and warnings.

.

Nice weather on Thursday and Thursday night for camping.  A slight chance for a storm will arrive late Thursday night but more likely Friday into Friday night.  Then additional storm chances over the weekend.

.
Significant to major flooding is likely to continue across the Missouri Valley in the coming weeks - latest river information - click here.
.
To follow the flood information along the Missouri River - click here for a special Facebook page that has been made for those concerned.

.
We are going to have to monitor the current pattern - these mesoscale thunderstorm complexes that keep moving through the region can produce heavy rainfall.  This will cause rivers to rise even further.  
.
The Ohio River is starting to back up because of the high levels on the Mississippi River.  This is going to be a concern for quite some time to come.  Those living along rivers should monitor updated forecasts.
.
To view the interactive river map below - click here.  The areas in purple and red are experiencing significant flooding issues.

Let's check out the how much rain is forecast to fall over the next 48 hours.  Keep in mind that during the summer months heavy thunderstorms can produce excessive amounts of rain in a short period of time.  This map is to give you a general broad brushed idea of what can be expected.  Some areas during the summer months will pick up very little precipitation while neighboring areas receive quite a bit.  Thus is the nature of thunderstorms and the summer pattern.

You can also now view the probability of X amount of rain (you pick the value on the web-site) in a six hour period of time.  Those maps can be viewed here.

Let's also take a look (the map below) at the expected heat index for tomorrow afternoon.  You can view this map for other days by clicking here.  Remember - the heat index is what the temperature feels like to your body when the temperature and humidity are combined.  Heat index calculator can be viewed by clicking here.

How much above or below normal will high temperatures be tomorrow?
.
The map below shows you the departure from normal highs (normal highs are around 82-85 degrees).  This gives you a general idea of the type of weather pattern we are in.  Warmer than normal or cooler than normal?  
.
For example if the normal high is 80 degrees and the actual high is 90 degrees then we would be 10 degrees above normal. You can find this map on the web-site, as well - click here.

You can see from the maps below that a large chunk of real estate to our south and west is experiencing drought conditions. You can view these maps by clicking here, as well.

.
Here is the Palmer Drought Index - this gives you an idea of where it is too wet and where it is too dry.  Extreme drought continues over parts of Texas (and surrounding areas)

You can now view the 6-10 and 8-14 day forecast maps for temperature and precipitation!  Maps are available by clicking here.

.
Not the best news for the summer forecast - the latest graphics are showing above normal temperatures.  We will have to see how this pattern evolves.  There is some disagreement among the models.  I am still holding out that the NW flow dominates and we see more below normal temperature days.
.

.
.
1.  We should dry out by Thursday

2.  More seasonable temperatures will arrive on Saturday - even some below normal temperatures.  


3.  Thunderstorm chances increase again on Friday - this will continue into Saturday and Sunday.  I suspect Friday night and Saturday could be quite wet.  Timing and placement of the thunderstorm complexes is a bit difficult this far out.  Will monitor and update accordingly. 
.
4.  Watching the tropics - there have been on/off hints of something trying to develop but so far nothing has found its legs.  We will continue to monitor.
