July 20, 2018: Monitoring the severe weather potential today and tonight.

1 PM Update

Interesting to note that the latest Hrrr model now shows no storms forming today.  There is a CAP on the atmosphere.  We will have to see if that CAP breaks.  Occasionally, these types of events don’t occur because of the CAP.

 

 

9 AM update

The latest high resolution WRF model shows storms forming early in the afternoon.

The latest Storm Prediction Center severe weather outlook

Dark green is a level one risk (the lowest).  The orange and red are the higher risk zones.  Don’t get too caught up on the exact placement of the colors.  Weather does not always follow our man-made lines.

The National Weather Service defines a severe thunderstorm as one that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.

 

Friday into Friday night:

We do have some concern today for severe weather.

There remain questions on exact placement and timing of the severe weather.

Thunderstorms have developed this morning in southeast Missouri and this is causing additional questions concerning this afternoons thunderstorms.

If we have more clouds then instability won’t be nearly as great.  Lower instability would tend to lessen the severe weather risk.

 

If the atmosphere does become unstable then the stage is set for all modes of severe weather.

Supercell thunderstorms are possible today.  Those type of storms are more widely scattered and can tap into the CAPE (energy).

I recommend you stay informed on the latest weather information.  Questions remain about the actual extent of the severe weather risk.

There will be an abnormal amount of wind shear today into tonight.  Wind shear is the turning of wind with height and/or the increase of wind speed with height.  This is one ingredient when forecasting severe thunderstorms.

 

Saturday through Wednesday:  For the time being it appears that severe thunderstorm chances will be low.  There will be at least a daily chance of widely scattered thunderstorms in the region.  Lightning would be the primary concern.

 

Summer thunderstorms can produce isolated microbursts.

microburst winds can exceed 50 mph.

What are microbursts?

Weather Headlines

  1. Some severe thunderstorms are anticipated today
  2. Unstable atmosphere could lead to several reports of large hail, damaging wind, frequent lightning, heavy downpours, and even tornadoes
  3. Weekend forecast is warm and humid
  4. We will have to deal with daily mainly heat of the day storms into next week

 

I will be sending out app/text messages today.

Make sure you have the tornado alert turned on.  That would be app/text option number one.  WeatherOne is its name.

You can find that within your www.weathertalk.com account under personal notification settings (remember, this is for paid accounts)

Don’t forget you can also turn on the severe weather day social media updates.  I will send you the latest Facebook update, blog update, and more.

 

 

The main weather concern today remains the risk of severe thunderstorms.

Everything appears to point towards the potential of a few thunderstorms this morning in the region.  For the most part, those would likely remain below severe levels.   I can’t rule out a severe thunderstorm warning.

Eyes then turn towards this afternoon into tonight.

A potent storm system will push into the Ohio Valley.  This system will set the stage for an unstable atmosphere as we move through this afternoon.

CAPE values are anticipated to exceed 3500.  That is high.  CAPE is potential energy for storms to tap into.  CAPE tends to be high during the Month of July.  This is mainly because of the heat and high dew points.

Of more concern is the potential of wind shear.

Typically, during July and August, our upper level winds are light.  Not a lot of jet stream energy.  Today, however, will be an exception to the rule.

Wind shear (the turning or increase of wind speed with height) is forecast to be more like late spring.  This will help produce severe thunderstorms.

Wind shear can help thunderstorms to remain severe for longer periods of time.

As always, there remain questions about how this event unfolds.

It appears that the greatest risk of severe weather will extend from the Missouri Bootheel into the extreme southern seven counties of southern Illinois, and then into Kentucky and Tennessee.

It is this area that the atmosphere should become the most unstable.

Storms could produce hail large than half dollars in some areas.  There is also the potential of wind gusts above 65 mph.  I can’t rule out tornadoes.

This is the kind of day where we hope for the best but be prepared in case severe storms form.

Storms will be moving from the west and northwest towards the south and southeast.  Storms should move at 30 to 45 mph.

Monitor updates today.

Here is the Hrrr model future-cast radar.

Time stamp is located in the upper left portion of the graphic.

This is one models opinion.

Notice how portions of the region remain free of thunderstorms.  That is quite possible today.  Some areas will have severe weather, but not all.

CAPE values.  CAPE is a measure of energy

 

 

Lift index values.  This gives us some idea on the buoyancy of the atmosphere.  You need that to lift air parcels upward.  That helps create thunderstorms.

 

 

Dew points.  Measure of moisture.  These are muggy dew points.
PWAT values.  PWAT is a measure of moisture in the entire atmospheric column.  High numbers equal heavier rain totals, typically.  These numbers are quite high.  Storms that form will produce heavy rain.
.
Wind speeds high up in the atmosphere.  These will be quite strong for July.  This is an important ingredient for the development of severe thunderstorms.
Notice how the wind is streaming in from the northwest.
Storms tend to move in from the northwest during the summer months.

 

The Storm Prediction Center has placed our region in a level 2, 3, and 4 risk zone.  Five is the highest.

The orange and red zone stand the greatest risk today of severe storms.  I would not let me guard down elsewhere, as well.

 

 

 

 

 

The July forecast has been updated. The heat will likely be the big story.

This outlook covers July 20th through July 26th

 

 

The precipitation forecast is PERCENT OF NORMAL. For example, if your normal rainfall is 1.00″ and the graphic shows 10%, then that would mean 0.10″ of rain is anticipated.

Always keep in mind, slow moving summer thunderstorms can produce torrential rain. That could skew the rainfall outlook.

WeatherBrains Episode 652

Tonight’s Guest WeatherBrain is a meteorologist at the Naval Research Laboratory. Dr. David Peterson, welcome to WeatherBrains!

Last year was a record year for wildfires across the globe, and their impact on the atmosphere remains highly uncertain. Thanks to new research from expert scientists at the U.S. Naval Research Laboratory, the world is gaining more insight into what drives these massive and escalating events. NRL meteorologist Dr. Peterson explained his findings from his recent research, “Wildfire-Driven Thunderstorms Cause a Volcano-Like Stratospheric Injection of Smoke,” during a press conference at the European Geosciences Union’s annual General Assembly in Vienna, Austria, held from April 8 to 13. “Our research shows that the stratospheric impact from five wildfire-driven thunderstorms, known as pyrocumulonimbus or pyroCb, was comparable to a moderate volcanic eruption,” Peterson explained the NRL pryoCb research team’s findings and that it’s an interdisciplinary collaboration with scientists from both the Marine Meteorology and Remote Sensing Divisions within NRL. The significance of volcanic eruptions in the climate system has been recognized for several decades, but pyroCb research is relatively new, originating at NRL in the early 2000s, according to Peterson.

Other discussions in this weekly podcast include topics like:

We offer interactive local city live radars and regional radars. If a radar does not update then try another one. If a radar does not appear to be refreshing then hit Ctrl F5. You may also try restarting your browser.

The local city view radars also have clickable warnings.

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

Did you know that a portion of your monthly subscription helps support local charity projects?

You can learn more about those projects by visiting the Shadow Angel Foundation website and the Beau Dodson News website.

I encourage subscribers to use the app vs regular text messaging. We have found text messaging to be delayed during severe weather. The app typically will receive the messages instantly. I recommend people have three to four methods of receiving their severe weather information.

Remember, my app and text alerts are hand typed and not computer generated. You are being given personal attention during significant weather events.
