HEADLINES:  
There will be some shower and thunderstorm chances tonight - Sunday - into early Monday morning.  No severe weather is anticipated.  A few storms could produce brief heavy rain and lightning.  Hail and gusty winds will be possible with the most intense cells.  Storms will be slow to move - rainfall totals of 1-3" will be possible in the heaviest cells (isolated amounts in that range).


The big story the rest of this week will be the warm temperatures.  Monday and Tuesday won't be too bad - Wednesday either.  But from Thursday on into the weekend we will experience temperatures in the 90s - humid, as well.


The drought will continue to strengthen.

Let's check out the how much rain is forecast to fall over the next 48 hours.  This map gives you a general broad brushed idea of what can be expected.  Remember the scale is at the top of the map.

Keep in mind that this is a broad-brushed view through Monday - some areas may not pick up much rain at all.  Locally heavy thunderstorms can always produce more rainfall.

Date Range:  May 28th-June 6th
Event: A larger scale system to impact the central United States
Severe Risk:  Yes - possible event. 
Details: Unsettled weather.
Confidence in my forecast.  Medium 
 
.
.
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.  More the unsettled weather back a few days - the ridge looks to be strong most of this week - this will keep storm systems further west.  Crossing fingers that we push into a more active pattern as we move into the end of the month and then first part of June.  We need rain - as you all know.


We will see how it goes.  


Very warm temperatures as we push through the upcoming week into the weekend - highs into the 90s will be common.

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!
