HEADLINES:  
Rain has arrived in the region - area radars are lighting up with a band of showers and isolated thunderstorms.  Hopefully most areas will pick up a little bit of rain.  We are running below normal in the rain department.


I am not forecasting any severe weather today.  Keep in mind that lightning will be possible in a few areas - if you have outdoor events then monitor radars.  When thunder roars - move indoors!


Here are the radars for you to view - click here

Temperatures will drop 10-20 degrees behind the cold front this afternoon/evening (Friday).

The good news is that I still do not see a widespread severe weather outbreaks in our near future - it has been unusually quiet for a long period of time.  We had a lot of severe weather in February and early March - it has been quiet since then.  The Gulf of Mexico waters are very warm - this led many forecasters to expect a lot of severe weather - including myself.  That has not happened.  Something to be thankful for.  

There will be quiet a few clouds around on Saturday - perhaps some clearing during the late morning then an increase in clouds again during the afternoon.  Sunday will bring a mix of sun and clouds - cool temperatures - below normal temperatures both Saturday and Sunday. 


Winds will also be gusty for the next few days - if you are going to be out boating then keep that in mind. 

Here are the high and low temperature forecasts for the weekend - it will be a bit on the chilly side (jacket weather?).

I would not be surprised to see some 30s on Sunday morning - as a matter of fact I have put 30s into the forecast for Saturday night.  

Here are the forecast lows for Saturday morning


Saturday high temperatures

How much below normal will temperatures be on Saturday and Sunday?  These maps below will show you!  Quite cool for the middle of April

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.  The next chance for precipitation will arrive around Wednesday or Thursday - right now it does not appear like a severe weather event.  I will monitor.


Fairly quiet weather overall for the middle of April.


You can see that a large chunk of the nation is in need of rain.

This first map below shows you how much precipitation is needed to end the drought - a fairly large chunk of the nation is dry.


Let's take a look at soil moisture anomalies - in other words how much below normal are soil moisture conditions.  The nation is the driest it has been in 5 years.


Let's hope we start to see a more active pattern - soon.

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!
