An explanation of what is happening in the atmosphere over the coming days…

Highlights

1.  Warm days continue!  Above normal temperatures.
2.  Just small thunderstorm chances
3.  Increasingly unsettled weather next week

Well, the warm beat goes on!  We are going to rack up a bunch of above normal temperature days.  At least through the weekend and likely into next week.

Numerous locations will likely be well into the 90’s Friday into Sunday.  Heat index values could even approach 100 degrees.  Some data (the GFS model) pops temperatures into the upper 90’s.  That seems a bit overdone.  Either way…it will be hot over the coming days.  Use care, as always.  Especially since it is a holiday weekend.  I know many people will be outside.

The good news is that the holiday weekend appears to be shaping up as mostly dry.  There will be a 10%-20% chance for some thunderstorms.  That means there should be some storms on radar from time to time, but isolated.  Odds favor your house remaining dry.  Not that you want it to remain dry.  Some of you have told me that you need rain.  It is becoming a bit dry.

We need to get some moisture in the ground before fall fire season.  That precipitation could occur next week.  But, let’s not get ahead of ourselves.

Let’s look at the last seven days of precipitation.  The percent of normal precipitation.  This indicates that it is indeed a bit dry.  Appears to be anywhere from 10%-30% of normal precipitation.  Dry.

2015-09-03_11-38-01

How much precipitation has fallen?  Keep in mind there are isolated spots that did pick up a heavy shower or storm over the last seven days.  But, most areas remain dry.

2015-09-03_11-37-40

So, the bottom line is that in the short term it has become a bit dry.  We need rain.

Speaking of rain!

Next week the pattern may shift a bit.  The ridge of high pressure that has been responsible for our hot and humid weather could shift back southwest and south.  If that happens it does open the door for the jet stream to dip southward again.  That would lead to increasing chances for showers and thunderstorms.

This would be in response to a cold front dipping in from the northwest and north.  The front will be accompanied by showers and thunderstorms.

As is typically the case in the long range the details are a bit murky.

There are currently two camps of thinking.

The first camp is the EC model.  I usually like the EC.  It does well in the long range.  The EC  breaks the ridge down on Monday and Tuesday.  It shows multiple rounds of showers and thunderstorms starting late Monday and lasting into Thursday.  Locally heavy rain and even some hefty thunderstorms would be a concern if the EC is correct.  Some spots could pick up several inches of rain.  Again, if the EC model is correct.

The other camp is the good ole GFS.  As you may remember, the GFS is not my favorite model.  But, sometimes it does okay.

The GFS would dip a cold front into our region by Wednesday or Thursday.  It is slower in breaking down the ridge vs the EC model.  It would also hold off the best rain chances until the middle of next week.

We have plenty of time to monitor all of this.  The good news is that most will remain dry through Monday.  Again, a few storms will pop up through the weekend.  Isolated, at best.

How much precipitation should we expect over the next few days?

No major widespread rainfall events anticipated through Sunday.  There could be a few scattered storms over the weekend.  Of course, this time of the year thunderstorms can produce pockets of very heavy rain.  Keep that in mind.  Even if it is isolated.

 

2014-11-24_13-38-04

Can we expect severe thunderstorms over the next 24 to 48 hours?  Remember that a severe thunderstorm is defined as a thunderstorm that produces 58 mph winds or higher, quarter size hail or larger, and/or a tornado.

Thunderstorm threat level will be near ZERO for Friday.  I could have gone with a ONE.  Very small thunderstorm chances.

.
Friday:  Severe weather is not anticipated
Saturday:  Severe weather is not anticipated
Sunday: Severe weather is not anticipated
Monday:  Severe weather is not anticipated
Tuesday:  Monitor updates
Wednesday:  Monitor updates

whatamiconcered

Hot weather will continue into the weekend.  There will only be small thunderstorm chances through Sunday night.  Anywhere from a 10%-20% risk.  That basically means there will be some storms on radar from time to time, but the odds favor your location remaining dry.  Of course some unlucky soul could have a rain shower on their picnic.

We have regional radars and local city radars – if a radar does not seem to be updating then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. That usually fixes the problem. Occasionally we do have a radar go down. That is why I have duplicates. Thus, if one fails then try another one.

If you have any problems then please send me an email beaudodson@usawx.com

We also have a new national interactive radar – you can view that radar by clicking here.

Local interactive city radars include St Louis, Mt Vernon, Evansville, Poplar Bluff, Cape Girardeau, Marion, Paducah, Hopkinsville, Memphis, Nashville, Dyersburg, and all of eastern Kentucky – these are interactive radars. Local city radars – click here

NOTE:  Occasionally you will see ground clutter on the radar (these are false echoes).  Normally they show up close to the radar sites – including Paducah.

Who do you trust for your weather information and who holds them accountable?

I have studied weather in our region since the late 1970’s.  I have 37 years of experience in observing our regions weather patterns.  My degree is in Broadcast Meteorology from Mississippi State University and an Associate of Science (AS).  I am currently working on my Bachelor’s Degree in Geoscience.  Just need to finish two Spanish classes!

I am a member of the American Meteorological Society.  I am a NOAA Weather-Ready Nation Ambassador.  And, I am the former Meteorologist for McCracken County Emergency Management.

I own and operate the Southern Illinois Weather Observatory.

There is a lot of noise on the internet.  A lot of weather maps are posted without explanation.  Over time you should learn who to trust for your weather information.

My forecast philosophy is simple and straight forward.

  • Communicate in simple terms
  • To be as accurate as possible within a reasonable time frame before an event
  • Interact with you on Twitter, Facebook, and the blog
  • Minimize the “hype” that you might see on television or through other weather sources
  • Push you towards utilizing wall-to-wall LOCAL TV coverage during severe weather events

I am a recipient of the Mark Trail Award, WPSD Six Who Make A Difference Award, Kentucky Colonel, and the Caesar J. Fiamma” Award from the American Red Cross.  In 2009 I was presented with the Kentucky Office of Highway Safety Award.  I was recognized by the Kentucky House of Representatives for my service to the State of Kentucky leading up to several winter storms and severe weather outbreaks.
