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

  1.  Fast moving system on Monday night.  Thunderstorm?
  2.  Nice weather Tuesday into Thursday.  Cooler for a couple of days.
  3.  Hot and humid.  First heat wave of the season?
  4.  Strong cold front early next week

Well, today has been beautiful!  Wish this would have happened on Saturday.  At least we had a nice day on Sunay.  Hope you were able to enjoy today’s weather.

A fast moving weather system will brush our region tonight.  It will approach from the north.  A few scattered showers and thunderstorms will be possible.  Lightning is the main concern.  Severe weather is not anticipated.

You can see the troughs and ridges on these next two maps.  Watch the change.  The first map shows you the 500 mb level for heights and vorticity.  The colors represent where some lift might be occurring.  An indication, depending on the placement of the vorts, for rain and storms.

This first one is for Tuesday morning.  A disturbance passes through our region and to the northeast of our region.  See the red lines?  Those are indicating which direction the wind flow will be during the time frame indicated.  We will have northwest flow on Tuesday.  Winds aloft will be coming out of the northwest.  The jet stream is dipping into our area.  A trough normally means cooler weather and sometimes unsettled weather.  It will mean cooler weather for our region.

Now, look at the second map.  See the big difference?  A ridge of high pressure builds into our region.  These ridges, during the summer months, can mean hot and humid weather.  And, they typically suppress thunderstorm activity.  Our winds will be coming out of the southwest and south.  The second map is for Friday and Saturday.  Hot weather is expected because of this ridge of high pressure.

What is a trough and a ridge?  Here you go – click here

tuesdaytrough

 

saturdayridgehighpressure

Tuesday and Wednesday will deliver beautiful spring weather.  High temperatures in the 70s to middle 80s.  Nice for this time of the year.  Not anticipating any precipitation on Tuesday into Wednesday.

We will start to warm up on Thursday.  Another weak disturbance moves through our area on Thursday night and Friday morning.  Another chance for a couple of thunderstorms in the region.  Confidence is low on that part of the forecast.

A mini-heat wave arrives on Friday into Monday.  I am currently forecasting widespread 90s for Saturday and Sunday.  It will feel hot and it will feel humid.  All of the recent rainfall won’t help our cause.  That will only make it feel more uncomfortable.

2016-06-06_11-37-50

The hottest day might be Sunday.  I can’t rule out middle 90s.  Guidance has been trending warmer.  You can see my forecast numbers above.  They are hot.  I consider hot weather to be 90 degrees and above.  Heat index values might hit 100 degrees this weekend.

Here is what the GFS guidance is showing for high temperatures Saturday into Monday.

Watch the change in dew points.  Dew points are a great way to measure moisture in the air.  Better than humidity.  To learn more about dew points you can click here.  When the dew points rise into the 60’s it will start to feel humid outside.  When they reach 70 degrees or above you can expect to feel uncomfortable.  Very humid and sticky.  The atmosphere feels muggy.

Here is the dew point map for Tuesday.  Notice the 50’s over our region?  Drier air.  Should feel nicer outside on Tuesday and Wednesday.

wednesdaydryair

But, watch what happens by Friday and Saturday.  OUCH!  Dew points jump into the 60’s and perhaps even 70’s.

fridaydewpoints

Early next week the dew points are expected to be very high.  Into the 70’s.  Muggy.  That means air that you wear (as Jim Rasor says).  Very humid.  Lot of fuel for storms, as well.  We will have to monitor the cold front moving into the region early next week (assuming it does move into the area).

Mondayveryhuimid

Early next week, a strong cold front is anticipated to bump into the hot air.  This would occur on Monday or Tuesday of next week.  Long way off for a forecaster.  But, that is what I will be tracking.  Thunderstorms will erupt along and ahead of the cold front.  Some disagreement on where to place the strongest wind fields on Monday and Tuesday.  I suspect somewhere from Iowa/Wisconsin/Missouri/Illinois/Indiana/Michigan will be under the threat of heavy rain and strong storms.  Too far off for solid specifics.  But, that is what I am tracking.  Monitor updates.

Here are the PWAT values for Tuesday and then early next week.  These are the PWAT anomalies.  How much above or below normal will they be.  PWAT values are a GREAT way to measure the moisture of the entire atmosphere (top to bottom).  Notice brown colors on Tuesday.  Dry air.  Notice the blue and greens next week.  Moisture will be plentiful for any storms that form.

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

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.

.
Monday night:  Perhaps a thunderstorm.  Non-severe.
Tuesday-Friday:  Severe weather is not anticipated.  Small chance for a thunderstorm on Thursday night and Friday.
Next Saturday-Sunday:  Should be dry
Sunday night into Wednesday:  Thunderstorms are possible.  Monitor updates.

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

 .
A couple of storms possible on Monday night.  Rainfall totals of 0.40″ or less.  Another chance Thursday night.  Low confidence.  Heavier rain will be possible next week.
Here is the official rainfall forecast numbers from Monday night into next Monday.  The WPC has our region with no measurable precipitation.  However, there will be at least some chance on Monday night and perhaps Thursday night.  Just keep that in mind.

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.

My resume includes:

Member of the American Meteorological Society.

NOAA Weather-Ready Nation Ambassador. 

Meteorologist for McCracken County Emergency Management.  I served from 2005 through 2015.

I own and operate the Southern Illinois Weather Observatory.

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. 

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.

I am also President of the Shadow Angel Foundation which serves portions of western Kentucky and southern Illinois.

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
