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

Thursday night: 
Severe weather is not anticipated at this time.
.
Friday: 
Severe weather is not anticipated at this time.
.
Friday night:   Widespread severe weather is not anticipated at this time.  Thunderstorms will be possible late - a few of the storms could produce hail and high winds
.
Saturday: Thunderstorms will be possible.  Some of the storms could produce hail and damaging winds.  There is much uncertainty on the exact placement of severe weather - right now it appears that a line or two of storms may form - if so then high winds would be the main concern.


Saturday night into Sunday - same set-up.  A few thunderstorms may be severe with hail and high winds.   


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.


.
Friday's severe weather outlook graphic - you can see the warm front returning.  The SPC has marked off an area where severe storms might form along and ahead of the warm front.  The long orange area - that is where they have outlined a risk for a few severe storms.  Just barely clips our region - I will monitor for updates. 
.

.
.
Then here is the Saturday outlook (below) - you can see the SPC has outlined an area to our north and west - this is in association with a complex of thunderstorms that is forecast to develop and move southeast.  For the time being we are not included in the risk zone.  I will monitor for any updates.  I think our main concern on Saturday will be lightning and some rain.

HEADLINE:   Wow - what a B E A U T I F U L day Thursday was.  Spring like weather - something we have been missing over the last month.  Seems like we have not had many nice days over the last month or two.  I hope everyone was able to enjoy their day.

.
Friday will once again bring pleasant conditions.  The only wrinkle in the nice weather is going to be the return of the warm front on Friday night and Saturday.  This warm front will move north into the area and help spark some showers and thunderstorms.  These on and off rain chances will continue all the way into the weekend.  NOW - it won't rain all the time - so don't cancel any outdoor plans - but be aware we may have some thunderstorms scattered about - lightning is always an issue during thunderstorms.  If you have plans on the lake then perhaps check radar before you head out and be aware of changing weather conditions.
.
Complicated forecast in trying to time these little waves of energy moving through the area.  So - check back and I will update the blog - at the top of each day's post. 

.
Temperatures will average below normal to near normal over the next few days.  The longer range models show us warming up again next week.  Once we are south of the warm front then temperatures will likely return to the 90s.  
.
The risk for severe storms over the next two or three days appears to be on the low side.  However, with that said - a few severe thunderstorms will be possible over the coming days.  When we do get a thunderstorm complex moving through the area it can produce frequent lightning and gusty winds.  Much like we experienced over the past week or two.  Scattered severe reports.
.
The Louisville National Weather Service Office did a great job on the tornado event Wednesday night.  Several tornadoes were reported in the Louisville area.  If you would like more information on the Louisville tornadoes - click here 
.
Here is some video of the storm that hit the Louisville area - click here
.

.
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, North Dakota (serious river flooding in that city) - 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.

Friday will be pleasant.  Thunderstorm chances increase on Friday night into Sunday (very small chance for a few storms on Friday afternoon).  I wouldn't cancel my outdoor plans - but I would be aware that a few thunderstorms could impact camping areas.  Lightning is always a concern when thunderstorms are around.  Gusty winds can not be ruled out with any storms that do form.  Just be aware of changing weather conditions and act accordingly.  Common sense, as always.

.
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.
.

Let's check out the how much rain is forecast to fall over the next 72 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.

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 that we are finally experiencing some below normal temperatures - the blue area.  This is more in line with what I thought late June would bring - but the question remains - how long will it last?  Will the majority of July bring above or below normal temperatures?  I am certainly sweating the summer forecast. There are quite a few models that show above normal temperatures returning next week. But, I am holding out that we see more of the NW flow and Canadian high pressure building south - keeping us from going above normal.

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.


.
The maps below show you just how extremely dry it has been to our south - this is how much precipitation is needed in order to end the drought.  Incredible amounts in Texas and Louisiana - some places need MORE THAN 20 INCHES OF RAIN!  Frustrating situation for those living in drought.
.
.

Here is a zoom in on Texas and Louisianan

.
1.  Unsettled pattern for the weekend. 

2.  Severe weather risks appear low over the next few days.  Main concern will be lightning - if you are camping or if you have outdoor events this weekend then just be aware of possible thunderstorms. 
If there were to be severe weather then high winds would probably be the biggest threat.
.
3.  The long range appears HOT.  Will be watching this pattern - will puncture a hole in the July forecast for mainly below normal temperatures.  We will see how it goes.
