August 19th and 20th: Warm!

Sunday Facebook update https://wtalk.co/PFXAF29U

Severe Weather Outlook

Today through Monday night.

Isolated storms are possible.  They are not anticipated to be severe.  Lightning is the main concern.  A few downpours.  Gusty winds.  Most areas will remain dry.

Tuesday and Tuesday night

A cold front enters our region with a chance for widespread showers and locally strong thunderstorms.  Severe weather can’t be ruled out with the cold front.  Monitor updates.

Sunday, August 20, 2017

Good day, everyone!
.
We are almost there! No real changes in the forecast for the next 48 to 72 hours.

A few concerns remain.

1. Cloud cover. Timing of cloud cover, Extent of cloud cover.
2. Overnight thunderstorm complex north and west of our region.
3. Air temperatures and heat index values.

First, let me say that it will be muggy through Monday night. Actual air temperatures today will range from 90 to 95. Isolated hotter areas possible.
Actual air temperatures on Monday will range from 88 to 94 degrees. Highs on Monday will be highly dependent on cloud cover.

Heat index values today of 98 to 106 degrees.

Heat index values on Monday of 96 to 104 degrees.

Obviously, heat related illnesses are a concern for outdoor gatherings. Especially true for tourists that have come into our region that may or may not be acclimated for these conditions.

Anyone in charge of outdoor events should have plenty of water on hand. Common sense heat safety rules.

A few thunderstorms are possible today into Monday. Many will remain dry.

Questions remain about cloud cover on Monday. The greatest cloud cover should be over portions of southeast Missouri and southern Illinois.
Some clouds are certainly possible over Kentucky and Tennessee, but percentage coverage is questionable.

Two possible scenarios.

We have a thunderstorm complex over northern Missouri this morning. Satellite images indicate clouds moving northwest to southeast into our region. This will leave an outflow boundary later today (a boundary where old storms die off and new ones could form).

This boundary may ignite some storms later today/this afternoon. We already had a couple of showers/storms on radar over southeast Illinois/southwest Indiana.

Any showers and storms that do form today, mainly over southeast Missouri and southern Illinois, will weaken during the evening. That will leave some high clouds in the region.

Later tonight, another thunderstorm complex is likely to form over northeast Kansas, Iowa, and northern Missouri. The timing of that thunderstorm complex is key to our forecast. How far south it forms is also important.

Wind fields today are oriented such that clouds are moving northwest to southeast. On Monday, however, the wind fields aloft will be a bit more west to east.
That raises questions on what happens to the thunderstorm complex over Missouri and Iowa. It will certainly have plenty of clouds associated with it. Both high cirrus clouds (blow off from cumulonimbus clouds) and cumulus clouds will be present in and near the complex.

Some of those clouds will likely impact at least portions of southeast Missouri and southern Illinois.

How fast we heat up on Monday morning will be key to new cumulus clouds forming. Typically, during the heat of the day, you see cumulus clouds bubble up as heat rises from the warming earth/ground temperatures. These air parcels rise and as they rise they expand and cool. Eventually the air parcels reach the condensation level and form clouds.

The forecast remains unchanged. A mix of sun and clouds, especially over Missouri and Illinois. Better chances for less clouds over Kentucky and Tennessee.
.
I will monitor today’s data. The model guidance has been worthless the past few weeks. Thus, most of the models have been thrown out for today and tomorrow.

A severe thunderstorm is defined as a storm that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.  That is the official National Weather Service definition of a severe thunderstorm

Sunday: A 20% to 30% chances for showers and thunderstorms.  That means there will likely be a few showers and storms on radar, but many will remain dry.  Saturday morning storms could be intense.

Monday will be warm and humid.  A few thunderstorms are possible.  Severe weather is unlikely.

Tuesday will be warm with a cold front moving into the area.  Strong storms are likely along the front, but timing of the front is still in question.  It could arrive Tuesday night.  Monitor updates concerning Tuesday.

Lightning will be the main concern over the coming days.  Small risk for strong winds with the most intense thunderstorms.  Locally heavy downpours.

Short update.  Today is a travel day for me.

Heat is a concern for Sunday and Monday.  Heat index values of 100 to 105 will likely occur during peak heating.  Use care.

We have regional radars and local city radars – if a radar does not update 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.

During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.

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 39 years of experience in observing our regions weather patterns.  My degree is in Broadcast Meteorology and a Bachelor’s of Science.

My resume includes:

Member of the American Meteorological Society.

NOAA Weather-Ready Nation Ambassador.

Meteorologist for McCracken County Rescue.  2015 through current

I own and operate the Southern Illinois Weather Observatory.

I am the chief meteorologist for Weather Talk LLC.  I am the owner of Weather Talk LLC.

I am also a business owner in western Kentucky.

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, email, texts, and this blog
  • Minimize the “hype” that you might see on some television stations or through other weather sources
  • Push you towards utilizing wall-to-wall LOCAL TV coverage during severe weather events
