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

Highlights

1.  Summer warmth this week
2.  How is the front looking for early next week
3.  Long range active weather starting to show up as seasons change?
4.  Let’s review my August forecast

Above normal temperatures will continue on Tuesday.  This as high pressure dominates our region.  Ridge of high pressure during the summer months equals warm/hot temperatures.  And, this week will deliver just that.

Expect temperatures to stay warm right on through the weekend.

Here is the low temperature forecast for Wednesday morning

2015-09-01_10-46-31

and the high temperature forecast for Wednesday

2015-09-01_10-46-14

How about the departures?  How many degrees above normal will temperatures be on Wednesday?  Several!

2015-09-01_10-47-57

If you read yesterday’s post you will remember that I am tracking a cold front for early next week.  Some questions remain on the strength of the front and the timing.

Models have not been in agreement on this topic.  The GFS model and ensembles want to bring the front through the region by Monday.  The EC model, however, wants to stall or weaken the front well to our north.  The difference means rain vs dry weather for Sunday and Monday.

Right now the consensus in the data is to slow the progress of this front and associated disturbance until Monday or Tuesday.  Models have been trending slower and slower with its passage.  Trends are always important.  Trends are what meteorologists monitor to get a feel as to which direction the data is moving.  A slowing trend would be good news.  It might mean Sunday and Monday remain dry.

I will continue to monitor the data.  I have kept chances for precipitation small for Sunday and Monday.

This is the latest GFS model.  See the pink/purple/blue colors?  That represents rainfall.  You can see an area of low pressure north of Minnesota.  Cold front would trail back into the Central Plains.  Yesterday the GFS model had the front over our region on Monday.  Now, it has slowed down a bit.

The data is likely correct on there being a cold front to deal with next week.  The question will be timing and strength.  For now I will keep rain chances low for Sunday and Monday.  And, if we are lucky then it will just remain dry for the holiday weekend.  I say lucky…some of us could use rain.

avn_144_sfc

Here is the GFS surface map projection for Tuesday night.  The front still remains to our west and is actually weakening.

avn_192_sfc

If you remember from past posts, I always tell you that the GFS is one of the worst models.  The EC said Sunday and Monday would be mostly dry all along.  Appears the EC may once again be right.  I can’t post the EC maps because of copyright laws.  They don’t like their data shared.

Still several days to monitor this cold front.  I will track it and update accordingly.

The main story this week will be dry weather and warm/hot weather.  Expect little change day by day through the weekend.  High temperatures in the upper 80’s and lower 90’s.  Light winds, overall.  Lows in the upper 60’s to around 70 degrees.  Little in the way of precipitation chances.

One item of interest in the long range (10-16 days) is that I am starting to see signals of the seasons starting to change.  A more active jet stream.  Possibly a more active weather pattern.  Models do not handle change well.  The changing of the seasons typically throw the models into a bit of chaos.  Especially the further out you look ahead.  But, it is something I am starting to see in the data.

I know our quiet weather will not last.  It never does during the fall months.

My summer forecast was for the Missouri and Ohio Valleys to have below normal temperatures and above normal precipitation.  Here is the temperature verification

Everything in green was below normal in the temperature department.

And here is the precipitation chart.  Well above normal precipitation occurred over a very large area.

Overall the summer forecast turned out pretty much as expected.  There were some hot days in July.  It felt hotter because of the very high dew point readings.  But, overall the numbers for June, July, and August spelled below normal temperatures and above normal precipitation.
AUGUST REVIEW (will post it again today in case you missed it on Monday)

My August forecast was for the majority of days to deliver at or below normal temperatures.  My precipitation forecast was for normal to above normal totals.

Without a doubt the temperature forecast more than verified.  Temperatures were mostly below normal.  Impressive numbers for an extended period of time.  Coolish for much of August.  I think many of you enjoyed the August weather pattern.

The precipitation across our region was mixed.  Some spots had well above normal rainfall.  Some of you had normal rainfall.  And, quite a few spots were drier than normal.

Here are some charts showing you the August numbers

Here was the temperature anomaly for August.  Quiet impressive anomalies.

ncep_cfsr_noram_t2m_anom

Precipitation was a bit mixed.  Some places had a lot more rain than others.  That is not uncommon during the summer months.  Slow moving thunderstorm complexes can drop a lot of rain on some counties while neighboring areas miss out.

These maps are from the High Plains Regional Climate Center.

This  first map shows you how many inches of rain fell during August.  Much of the area ended up with 1-2 inches of rain.

rainfallmonthly

Here is a map from weatherbell.com   This shows how much rain fell over the past month.  Hard to read.  Scale is on the right.  If you are good at geography then you should be able to find our region.   Heaviest rains in our region were over southern Missouri.  Click to enlarge

nws_precip_ky_30

This next map shows you the percent of normal rainfall.  Some places had more than 150% of normal rainfall.  Other areas had 50%-70% of normal rainfall.  Quite a wide range across our region.

2015-08-31_12-05-37

And, finally this is the departure from normal rainfall in inches.  Parts of our region were 1 to 1.5″ below normal.  Other areas were 1.5-2″+ above normal.  Again, a wide range of rainfall totals over the region.

2015-08-31_12-05-14

Let’s look back at the summer (June through August).  Check out the flip in temperatures.  The chart below shows you the high and low temperatures for June through August.  The solid blue bars are the high and low temperatures.  In June we had numerous days above normal (red rectangle).  Then look at August (right side of the chart).  Much of August was below normal in the temperature department (blue rectangle box).  The Paducah, KY NWS only hit 95 degrees twice during the summer months.

Zooming in on August.  All the yellow areas represent below normal temperature days.  This is for the Paducah, Kentucky area.

The blue bars are the high and low temperatures.  The red line represents the record high for that day.  The light blue line represents the record low for that day.  The brownish area represents what normal values should be.

2015-08-31_15-33-50

And, it was a very wet summer.  Check out these numbers.  The brown line represents normal rainfall.  The green line is this years rainfall.  Well well well above normal.  This chart shows you June through August.

2015-08-31_15-24-13

My September forecast is for more days to be at or above normal in the temperature department and drier than normal in the precipitation department.  We will see how it goes.  There are some cracks starting to show up in the data for the second and third week of the month.  Meaning, colder than normal temperatures.  If that happens then it could bust my September forecast thinking.  We will see how it goes.

Remember that long range forecasting is usually low confidence forecasting.

My October forecast is for below normal temperatures.  Not sure on precipitation just yet.

All signs point towards a colder than normal winter.

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.
