No major concerns in our immediate local area for the next 24 hours.

.

.
No major concerns through Tuesday evening in our immediate area.  Some storms may approach our northern counties late on Tuesday night and early Wednesday AM.

.


The wild card in this forecast will be precipitation coverage on Wednesday.  The latest data is a bit more bullish on activity forming on Wednesday late morning and afternoon.  A few of the storms could be fairly robust with gusty winds, brief heavy rain, lightning, and perhaps some hail.  Monitor for updates.

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee
.
HEADLINES:  
Wow - the warm weather just keeps on going.  This is the Energizer Bunny of warm spells.  Temperatures remain anywhere from 10-30 degrees above normal over a wide part of nation.  There is little doubt that March will be one of the warmer ones on record for this region.  We will see where the final numbers end up.
.
A storm system will approach from the north on Tuesday night and Wednesday.  This system will push a cold front southward - along and ahead of the front there will be a chance for showers and thunderstorms.  
.
The Storm Prediction Center has outlined a slight risk for severe weather on Tuesday night across parts of Missouri into Illinois - this is mostly north and northwest of our immediate local counties.
.
Here is that graphic
.
The orange area is the slight risk zone - the yellow is the general thunderstorm risk outline.  Again this is the TUESDAY and TUESDAY NIGHT outlook.  We will have to wait and see about Wednesday.  Instability is definitely there on Wednesday but wind fields are weak - risk appears low.
.

.
There will be a chance for instability to gain some momentum on Wednesday in our area.  CAPE values of anywhere from 500-2000 appear likely.  That is quite a bit of energy.  Wind fields are, however, weak.  This will help keep the severe weather risk fairly low.  I would not be surprised to see some reports of gusty winds and hail.  Monitor for updates.  Right now the SPC does not have us in a risk.  We will see if that holds - either way the risk appears low.  They will post an update later tonight concerning Wednesday.
.
Here is what the NAM Model is showing for CAPE values over our region - decent instability.  This image is from www.wright-weather.com
.

.
Thursday should be dry as the front pushes further south.
.
High temperatures for Tuesday and Wednesday over our region - WARM will be the word!
.
It isn't warm everywhere - at least tonight (Tuesday night) won't be - check out the frost and freeze advisories to our east - northeast.  The light blue and blue areas are the advisory areas.  This does include parts of eastern Kentucky.  You can read the text's here
.
There isn't much snow left in the nation - much of Canada's snow has also melted.  This could cause significant problems for river flow later this summer.  Meaning - lack of flow.
.
An unsettled weekend may be on tap for our region - into next week.  See the extended for details.

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.  Rain chances will once again increase Friday into Saturday - a strong system will produce a more widespread rain event in our region - especially on Saturday.  Right now the severe weather risk appears low.  I will monitor and update.
.
Sunday - at least right now - appears dry.
.
A stronger storm may impact the region early next week - strong cold front with thunderstorms.  Cooler air behind it, as well.  Long way off - plenty of time to update on that event.  Models do not agree on the outcome.
.
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!
