Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...
.
Tuesday night:  Mostly cloudy with scattered showers and thunderstorms.  Mild for early April.  To view radars - click here.
Above normal temperatures
Lows: in the lower to middle 60s  |  Normal lows for this time of the year are around 43 degrees.
Wind:  Southwest winds at 5-10 mph.  
Precipitation probability - 40%   | Rainfall totals:  0.25"-0.50" in areas that experience rain.  Isolated thunderstorms can always produce higher rainfall totals.  Not everyone will pick up rain tonight.
Confidence in this forecast is very high
.
Wednesday:  A mix of sun and clouds - an increasing chance for showers and thunderstorms as the afternoon wears on.  Mild.  To view radars - click here. Above normal temperatures
Highs:  around 72-78 degrees.  | Normal highs for this time of the year are around 65 degrees.
Wind: Southwest winds at 5-10 mph
Precipitation probability - 60% especially late in the day  Rainfall totals:   0.25"-0.50" in areas that pick up rain
Confidence in this forecast is very high

.
Wednesday night:  Showers and thunderstorms likely.  To view radars - click here. Above normal temperatures
Lows: in the upper 50s and lower 60s |  Normal lows for this time of the year are around 43 degrees.

Confidence in this forecast is high
.
Thursday:  Cloudy and not as warm - scattered rain and rumbles of thunder possible.  
Near normal temperatures
Highs:  around 60-65 degrees - temps may vary a bit across the area (this will depend on cloud cover and precipitation) | Normal highs for this time of the year are around 65 degrees.

Precipitation probability - 60%  Rainfall totals:  0.25" 
Confidence in this forecast is high

There will be a chance for a few strong (isolated severe storms) Tuesday afternoon and evening.  Large hail would be the main concern along with a few high wind reports.  This is a marginal risk - meaning widespread severe weather is not anticipated.


Wednesday - a few storms could produce heavy rain and even a report or two of hail.  The severe weather risk is small.  Isolated.  The bigger concern will be lightning - for any outdoor events.  Monitor radars.   The best chance for showers/storms will be later in the afternoon into the overnight hours.


Thunderstorms will also be possible into Thursday - lightning is always a concern for outdoor events.  

Monitor local radars if you have outdoor events planned.  To view radars - click here.

.

.
If you have outdoor events you will want to monitor the weather over the next few days - lightning will be possible along with an isolated severe thunderstorm threat this afternoon and evening (Tuesday). 

.


Temperatures on Thursday may be the wild card on this forecast - some of the data shows temperatures in the 50s during the afternoon over parts of our area - warmer towards KY/TN line

The forecast for severe or extreme weather

The McCracken County Office of Emergency Management reminds you that owning a NOAA All Hazards Weather Radio is the best way to receive notifications of severe weather watches and warnings.
.
Remember that the National Weather Service defines a severe thunderstorm as one that produces 58 mph winds or higher, hail 1" in size or larger, and/or a tornado.  More information with some slides concerning reporting severe weather - click here

click here for the latest watch and warning map.
Tuesday night: 
Will there be a chance for non-severe thunderstorms? Yes
.
Wednesday:  Widespread severe weather is not anticipated - if there is enough instability then I can't 100% rule out an isolated severe storm - hail being the main concern.

HEADLINES: 
Another very warm day for our region.  Temperatures this afternoon (Tuesday) have risen into the upper 70s and lower 80s over the region.  This is well above normal for early April.

Check out these departures for today (Tuesday).  This map shows you how much above normal temperatures were on Tuesday - 10-20 degrees!  

 And it isn't just here - this is the national map showing you the departures.  WELL above normal temperatures over a large area of the nation.





A disturbance moving through our region will spark some showers and thunderstorms Tuesday afternoon and into the overnight hours.  A few of the storms may produce large hail and gusty winds.  The Storm Prediction Center has placed our region in a slight risk for severe weather.  Basically that means that a few severe thunderstorms will be possible but widespread severe weather is not anticipated. 


Click here for the latest watch and warning map.


Remember that thunderstorms produce lightning - if you have outdoor sports events or other events then you should monitor radars.  To view radars - click here.

Here is the severe weather outlook for this evening and overnight (Tuesday) - we are in or close to the slight risk zone.

The Wednesday outlook shows the orange (slight risk) for portions of our region.  The yellow area just means general thunderstorms are forecast (general means they are not forecast to be severe)

Remember that this map typically changes several times as the SPC updates their outlook.



Let's take a look at the high temperature forecasts for Wednesday into Friday - you can see that temperatures are going to be slightly cooler (but still mostly above normal).  This is partly because of clouds and rain chances - also the upper level low pressure area will be moving through our region.  This will provide an opportunity for temperatures to be not quite as warm as recent days.


 And let's take a look at the departures for Wednesday into Friday - again the departures show you how much above or below normal temperatures will be in our region.  Note that the dates are on the top of these images - you can also view these for yourself on the web-site - click here



Thursday may be the coolest day of the week - this will be even more true if we stay socked in with clouds and some precipitation.  I may need to lower high temperature forecasts for Thursday.

Some of the computer data shows temperatures into the 30s on Friday morning - I will monitor and update. 

One last image - check out the cloud tops down in Texas - these are the severe storms that brought tornadoes to the Dallas area.  The deep red colors are high thunderstorm tops



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

Remember that as a general policy, in the long range outlook, I try not to mention severe thunderstorms more than 72 hours in advance (unless the signal is so overwhelmingly convincing that it warrants a mention).  I will mention thunderstorm risks and I will give as many details as possible.  Also remember you can view the long range severe weather outlooks by visiting the Storm Prediction Center's web-site - click here

-----------------------------  


1.  Friday and Saturday should be mostly dry in our region - Saturday could be the pick day of the week.  

Temperatures will be cooler on Friday morning - some data is showing temperatures falling into the 30s - I will monitor and update as more data becomes available and I have a clearer picture of just where temperatures might end up.


A cold front will approach on Sunday.  This will bring some clouds and a chance for a few showers.  Right now it does not appear that severe weather is likely with the cold front.  I will continue to monitor and update.  


There is a chance for cooler weather as we move later into next week.

Seasonal outlooks can be viewed on the web-site - click here

Now is a GREAT time to buy a NOAA All Hazards Weather Radio.  Better to have one before storms strike than to be without one during an event.  I recommend the Midland Model 300 NOAA All Hazards Weather Radio - that is what I use here at my house!
