July 20th-23rd: Warm - not quite as humid Saturday

July 20th-23rd - 2012
Friday through Monday update


I am in summer mode - that means I try to update every other day or every 2-3 days.  If the weather is active then I will come in and update the forecast as needed.  I will also note an update at the very top of the blog update.

I also add new graphics and tweak the forecast during the day and evening hours - so check back for updates.

Here are my current personal forecast thoughts for far southern Illinois and western Kentucky..

Friday:  Partly cloudy - hot but not as muggy.  A chance for a few showers and thunderstorms - mainly over our southern counties KY/TN border and into Tennessee.
Above normal temperatures
Highs: in the lower to middle 90s |  Normal highs for this time of the year are around 90 degrees.
Wind:  North winds at 5-10 mph
Precipitation probability - 20%  |  Rainfall totals:
scattered 0.25" thunderstorms can and often do produce heavier amounts - again this is mainly KY/TN border counties down into Tennessee.
Confidence in this forecast is high


Friday night:  Partly cloudy and mild.
Above normal temperatures
Lows: in the lower 70s |  Normal lows for this time of the year are around 69 degrees.
Wind:  North winds at 5 mph
Precipitation probability - 10% - mainly early over southern counties |  Rainfall totals:
0.00"

A chance for a few storms on Friday/Friday evening over our far southern counties - KY/TN border counties and down into Tennessee - further south you travel the better the chance - also into parts of south central Kentucky. 
Temperatures and dew points will be on the rise by Sunday into Monday.

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee
.
HEADLINES:  Strong to severe thunderstorms rolled through the region on Thursday and Thursday night ahead of a southward moving cold front.  A few of the storms produced wind gusts in the 60-70 mph range - some hail was also reported.  Not everyone experienced rain (what else is new).  Those who did pick up rain recorded anywhere from trace amounts to more than 1".  Many areas did remain dry - unfortunately.


One thunderstorm moved through southeast Missouri early on Thursday afternoon - I did a scan of the storm via radar - you can see the precipitation reaching to above 50,000' into the atmosphere.  The pink area is likely a hail core - this cell produced a severe thunderstorm warning.

Click the image for a full size view.

Radar on Thursday evening shows thunderstorms along and ahead of a cold front moving through the Ohio Valley - the front will bring lower dew points and humidity to the region on Friday into Sunday - although it will still be hot.


Check out the satellite imagery on Thursday evening - these are thunderstorms showing up on the IR image.  Some of the storms had tops over 60,000'.

Here is the dew point map for Saturday afternoon - dew points from 60-80 feel moist to muggy.  Dew points in the 50s will feel much better.  We have been experiencing dew points in the upper 60s to middle 70s.


Here is the Saturday forecast map from www.wright-weather.com
Click image for full size view - this map shows DEW POINTS (not temperatures)


But - don't get used to the lower dew points - they will be on the rise by Sunday

Drought continues to spread across the country - the latest numbers and drought forecasts showed no real hope for the foreseeable future.  

Check out these YEAR TO DATE departures in precipitation and temperature.  These maps are courtesy of the High Plains Regional Climate Center

First the percent of normal precipitation - 100% would be normal precipitation.  We are far far from that.


And now temperatures - YEAR TO DATE







Here is the official drought forecast from NOAA - this is a huge area of the nation covered in drought. 

Click image for a full size view of the drought forecast.  The dark red/brown area represents where drought is likely to continue or grow worse.









Hot weather will continue into next week - I suspect we will see more 100 degree readings over the next 7-10 days.  Our long and hot summer continues.


High temp forecasts - again the core of the heat will be to our west - but we will not escape the heat.  






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.

Let's check out the how much rain is forecast to fall over the next 72 hours (5 days).  This map gives you a general broad brushed idea of what can be expected.  Remember the scale is at the top of the map.

Remember that thunderstorms can produce locally heavy rainfall totals that will exceed the totals shown on this map.  The rain you see on here will mostly be on Friday - and mostly to our south.  Don't expect much elsewhere in the region

You can also now view the probability of X amount of rain (you pick the value on the web-site) in a six hour period of time.  Those maps can be viewed 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.  Heat - heat and more heat.  Drought will continue across our region - no real relief in sight.  We need a tropical system to help break our drought.  The Atlantic, however, is very quiet.  You can see in this satellite image below - lot of dusty/dry air coming off the African Coast.  This is not good news for those wanting to see some tropical activity.

The core of the heat over the coming 5-10 day period will continue to be just to our west - although we will still be hot.  Click image for a bigger view.

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!
