This forecast update covers far southern Illinois, far southeast Missouri, and far western Kentucky. See the coverage map on the right side of the blog.

Remember that weather evolves.  Check back frequently for updates, especially during active weather.

Temperatures on Monday were a large bust over some of my forecast counties.  At 1 pm some counties were still in the 50s.  That is embarrassing.  Everyone was supposed to pop into the upper 60s to lower 70s.  Clouds did not scour out as fast as forecast.  Thus, for some, a temperature bust.

There was also drizzle over parts of the area.  Not the best day for forecasting!

Monday night –  Some clouds, fog, and drizzle possible.  Dense fog in some areas.

What impact is expected?  Some wet roads and perhaps lightning.  Gusty winds.  Monitor the severe risk.

Friday –  A chance for showers and thunderstorms as a cold front moves through the area.
Temperatures:  Highs in the upper 60s to around 70 degrees.
Winds:  Southwest winds becoming northwest after frontal passage.
What is the chance for precipitation?  40%-60%
Coverage of precipitation?  Scattered to perhaps numerous
My confidence in this part of the forecast verifying is   Medium
Should I cancel my outdoor plans?  No, but let’s monitor trends

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

Highlights

1.   Mix of sun and clouds.  Mild temperatures over the coming days
2.  Cold front arrives on Thursday afternoon into Friday morning.
3.  Showers and thunderstorms will accompany the front

Clouds were hard to shake on Monday.  This is not uncommon during the fall months.  Low level moisture can be difficult to scour out.  And, that was the case on Monday.  I was hoping the clouds would have moved our sooner.  The cloud cover helped keep temperatures down.  Unfortunate, because full sunshine would have warmed everyone into the 70s.

Terrible forecast today with the low clouds sticking around much longer than anticipated (at least for some). This is a common problem during the Month of November (and winter months for that matter). The lower sun angle doesn’t help our cause.

Low clouds and fog coverage much of the area this morning. The fog slowly mixed out, but the clouds did not. Warmer temperatures surrounding the low clouds helped slowly eat away at them. Slowly, being the operative word.

Some spots were still in the 50s as of 1 pm. Terrible forecast bust for those areas. Highs were supposed to be in the upper 60s to lower 70s. Some spots have reached those numbers, but not everyone.

Here is the visible satellite imagery at 1 pm.  See the white?  Those are clouds.  Stubborn clouds.

We also had quite a bit of fog on Monday morning.  Can’t rule out more fog for Monday night and Tuesday morning.  And, we may also have to deal with some cloud cover on and off the rest of the week.  Not saying the clouds won’t scatter.  They will.  But, at times it could be an issue.  And, we want this sunshine!  The reason we want the sun is because we will be situated in a warm air mass.  Mild by November standards.  If we can achieve sunshine each day then temperatures will warm into the 70s.

Let’s hope we can shake the cloud cover.

Our next big weather maker arrives on Thursday afternoon into Friday morning.  A cold front will sweep through the region.  This front will spark some showers and thunderstorms.  Right now the risk for severe weather appears fairly small, but perhaps not zero.  Let’s keep an eye on it.  I will update accordingly as we draw closer to the time frame.

We need to keep one eye on Thursday night and Friday morning.

GFS dew points rise into the 60s on Thursday night.  That is high for November.  This weatherbell.com map shows those dew points.

Dew points are a measure of moisture in the air.  If you see 60s in the fall and winter then it is a red flag.

CAPE is low, but shear is high.  Low CAPE and high shear in the fall and winter is also a red flag.  That means to monitor updates.

Then the 850 mb wind fields.  They increase quite a bit on Thursday night.  The first image is early in the evening and the second image is late in the evening.  Those dark red colors are some very strong winds at the 5000′ level.  The jet stream and low level jet will increase overhead.

Then early early Friday morning.

Otherwise, most of this week will be fairly nice.  Mild temperatures and hopefully some sunshine in between the cloudy periods.  Cross fingers on the sun.

Don’t forget we have interactive city view radars

Added mention of more clouds.  Sometimes clouds can be hard to shake during the late fall months.

No concerns through Wednesday

No

The wild card for the next couple of days will be cloud cover.  Sometimes in November the clouds can hang on longer than they are welcome.  Low level moisture.  Hopefully the sun will come out.

Small chance on  Sunday, November 8th or Monday the 9th.  Otherwise, not tracking any frost potential.

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

Good chance for showers and thunderstorms on Thursday night and Friday.  Right now we still have some time to monitor the potential for some thunderstorms embedded with the showers.  Perhaps some downpours.

Current rainfall outlook (subject to changes as we move forward).  This would be for Thursday evening into Friday morning.  Image is from weatherbell.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.

Thunderstorm threat level will be ZERO for Monday-Wednesday. 

.
Tuesday:  Severe weather is not anticipated.
Wednesday:  Severe weather is not anticipated.
Thursday:  Monitor updates.  Cold front arrives on Thursday evening and Thursday night.  Perhaps some storms.
Thursday night/Friday morning:  Can’t rule out a severe thunderstorm.  Low risk at any given location.  Main concern would be damaging wind gusts and short lived tornadoes.

Friday:  Monitor updates for early wee hours of Friday morning.  Perhaps some thunderstorms.
Saturday:  Severe weather is not anticipated
Sunday:   Severe weather is not anticipated.

I also set up a storm tracking page with additional links (use during active weather for quick reference)

Let’s take a look at some winter data.  I will keep adding to this over the coming weeks.  

UPDATE:  October 20, 2015:  Starting to see a more active pattern the last part of October into the first part of November.  A couple of storm systems to monitor.  I am noting the southern systems coming through the southwest United States.  The thinking is that this winter might end up a southern winter.  Meaning, a lot of storm systems will track through the gulf states and then off the southeast coast.  If there is blocking then the systems would push up the East Coast.  Typically this would be a great track for our region when it comes to winter storms.

The question will be how far south do these systems track.  Normally for heavy snow in our region we would look for a system pulling out of Texas and Oklahoma and then tracking into Arkansas, Tennessee, Mississippi, Alabama.  That would place our region on the cold side of the area of low pressure.

I do believe this is shaping up to be a fairly unique winter.  The warm waters off both coasts are not typical for an El Nino event.  Widespread above normal water temperatures in the Pacific and the Atlantic.  I will be monitoring Gulf of Mexico water temperatures.  Above normal waters in the Gulf of Mexico typically means increased severe thunderstorm activity along the Gulf Coast.  It could also mean more moisture for our winter storms to work with.

Drought continues to be the lead story.  Our dry pattern has been underway since September and October (for much of the region).  The long range cycle typically sets up during October and early November.  The longer our calm and dry weather persists the more I am concerned about drought during the winter months.

Precious discussions below.

One of my big concerns is how dry September and October have been over our local counties.  This is a concern.  I do believe in repeating patterns.  Typically October and November set the stage for the winter.  Let’s hope we start picking up more precipitation than we have been.

Let me show you some NOAA data.  They basically make their winter forecast 100% based on El Nino.  Personally I don’t like that approach, but every forecaster has their own method.  I believe that every El Nino is unique and is certainly not the only factor in a winter forecast.

With that said here are some typical El Nino graphics

Strong southern jet stream.  I agree with that.  Potentially dry in our region.  I am unsure about that.

Then there is this map

What would a typical El Nino winter look like?  Above normal temperatures over the northern United States.  Below normal precipitation in and near our region.  Again, this is what NOAA puts out.

My thoughts below:

Keep in mind that seasonal forecasts are more for fun than anything else.  No meteorologist can forecast details for the winter.  Will we have one big snowstorm?  Will we have a couple of big snow events?  It is the details that you care about.  The details can’t be forecast.

However, with that said…meteorologists can forecast some general ideas for an upcoming season.

As you may have read, I am leaning towards a colder than normal winter.  But, I am struggling with precipitation.  A powerful southern jet stream is forecast for the winter months.  We typically have two branches of the jet.  A northern branch and a southern brand.  That southern branch can produce some nasty weather conditions…including heavy snow, ice, and severe weather.

But, the real question will be the placement of the southern branch in relation to the northern branch.  When the two combine you can experience some of your bigger snowstorms.

The models are showing a drier than normal winter for our region.  Below normal precipitation.  Hopefully this won’t be the case.  I don’t like to enter spring in drought.  We have already experienced drier than normal conditions over Kentucky and Tennessee over the past month or so.  October has been dry, thus far.  And, that looks to continue.

Normally we start thinking about severe weather around the third and fourth week of October.  Also, we typically have one or two severe weather episodes in November.  Too soon to know if that will occur this year.

I am watching a storm system around the 14th-20th.

Back to the winter discussion…

A lot of models are showing below normal temperatures for our region.  Let me show you a few charts.

These particular forecast maps are from a Canadian model.  Images are from Tropical Tidbits.

This first map is for December.  The blue indicates lower than normal 500 mb heights.  The red indicates above normal heights.  Lot of blue across the southern United States.  That could be an indication of stormy weather.

This next map is for January

This next map is for February

This next map is for March

Let’s take a look at temperature anomaly maps

This first map is for December.  Blue colors represent below normal temperatures.  I am thinking this could be another back loaded winter.  Perhaps the harshest winter conditions will be in February and March.  Same as last year.

Here is the January temperature anomaly map from this particular model guidance.

This next map is for February.  That is a very cold look for February.

And, let’s take at look at March.

So, what does this mean?

Again, long range forecasting is more for fun than anything else.  But, the charts do point towards a cold winter for our region.  Perhaps the coldest part of the winter will be February into March.  Or, the worst winter conditions will be during that time.

Again, this is just one set of data.  There are a lot of other data sets to look over.

I like to move through the Month of October before banking on a winter forecast.

Let’s keep monitoring.

NOAA HAS RELEASED THEIR WINTER FORECAST

NOAA has released their winter forecast.  I have been forecasting below normal temperatures for our region.  But, I have not banked on precipitation, just yet.  The long range cycle is still in the developing stages.  The long range cycle typically develops during October and November.  It is a repeating pattern that will last through the winter.  Until we know what that cycle looks like then making a long range forecast for December into March is difficult, at best.

I am concerned about our dry weather.  October has been dry, thus far.  Not the best way to start out the next cycle.  However, we still have 4-6 more weeks to go.  Will the weather become more active during that time period?  Frequent cold fronts and frequent precipitation would be a strong clue as to what will happen in December-March.

Here is what NOAA said today.

This first map is their temperature outlook.  They are forecasting above normal temperatures across the northern United States.  In other words, the odds favor above normal temperatures.  The blue area, to our south, represents below normal temperatures.

I would have brought the blue further north into our region.  It is my forecast opinion that we will have a colder than normal winter.  That is when December into early March is averaged out.  That does not mean every month will be colder than normal.  It simply means the odds favor it averaging out to below normal.  We will see how it goes.

I base those ideas off the warm waters off the West Coast of the United States.  The last few winters have provided us with a lot of cold air.  If the high pressure in Canada shifts into western Canada then we will have plenty of cold air.

Our region is in white.  What is NOAA saying about our region?  They are saying there is a 50/50 chance for above or below normal temperatures.

Let’s look at NOAA’s precipitation forecast.  They are forecasting the southern United States to have a wetter than normal winter.  Drier than normal for much of the northern United States into the Great Lakes.  As I have said before, I am not ready to bank on a precipitation outlook.

Our region is in white.  What is NOAA forecasting for our region?  They are saying a 50/50 chance for above or below normal precipitation.

Remember, forecasters can’t actually tell you what you really want to know. How much snow will fall at my location. Will we have an ice storm. How many winter storms will impact our region.  If someone tells you that it is going to snow 8″ on January 15th then take it with a grain of salt.  Trust me, no forecaster can accurately forecast specific weather events months in advance.  Key word being specific.

We can have a drier than normal winter and a colder than normal winter and still be slammed by one or two big winter storms.

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.

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
