No major concerns - some lightning will be possible Sunday night and Monday.  Anyone with outdoor events should monitor radars.  The threat for severe weather appears very low.

Isolated storms are possible on Saturday, as well

I am posting information about the drought on the weather Facebook page - click here and hit like at the top of the page.
.



Monitor thunderstorms on Saturday and then Sunday/Monday - lightning will be the main - if not only - concern.




The wild card in the long range forecast will be the eventual track of Isaac - tropical system moving into the Caribbean and Gulf of Mexico.  This system, depending on the eventual track, could impact portions of our region.  Stay tuned for updates.

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee
.
HEADLINES:  The big story over the coming days will likely be Isaac - where will Isaac end up tracking?  That is the million dollar question.  Model solutions run all the way from Florida to Texas.  Those with interest or travel plans to the coastline should monitor updated forecasts on this tropical system.


There is some chance of Isaac impacting our local area - Future changes in the track of Isaac will be an important part of next weeks forecast.  For now we will just keep an eye on him.  You can track Isaac by clicking here.   Path forecast - click here.

A few thunderstorms will be possible on Saturday afternoon and evening.

A cold front will approach our region on Sunday night and Monday.  Moisture will be on the increase ahead of this next system.  That means it will feel a bit more humid over the coming days as dew points will be on the rise.  Temperatures on Friday into Sunday will be warm - mostly in the 90s (a bit above normal for this time of the year).

This cold front will be the focus for a few showers and thunderstorms - first to our west on Saturday/Sunday and then eventually spreading into our local counties by Sunday night into Monday.

It appears the best chance of precipitation will be late on Sunday night into Monday - across our local counties (early the further west you go).  Rainfall totals in the 0.25"-0.50" range can be expected in some of our counties.  Once again - as is usually the case in August - not everyone will experience rain.   

The risk for severe thunderstorms appears very low with this next cold front.  Wind fields are weak (typical for August).  

Drought conditions continue to plague our region - there has been little improvement over the past month.  We have picked up some rainfall - but not enough.  We need a lot of rain to bring us back to normal conditions.



Here are the normal high and low temperature maps for this time of the year - we are seeing them slowly fall as we move towards September.  Normal highs are in the 80s and normal lows are in the 60s.  


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

We have a number of new radars available on our Weather Observatory web-site!

We now offer St Louis, Mt Vernon, Evansville, Poplar Bluff, Cape Girardeau, Marion, Paducah, Hopkinsville, and Dyersburg Interactive City Radars.  We also have the two regional radars and now offer you three GR Earth radars.

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.  We will need to track Isaac over the coming week.

To track Isaac - click here

Here is the latest six to ten day temperature outlook.  Temperatures should average mostly above normal - SOME of this will depend on the eventual track of Isaac.  That is the wild card in the forecast.  Precipitation should be near to below normal over the coming 6-10 day period.  Again - that will depend on the track of Isaac, as well.

If you are a weather enthusiast then I recommend listening to WeatherBrains each week!  For a more in-depth look at what is happening in meteorology.




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!
