Wind forecast

This will be updated with a new graphic around 8 AM

 

.

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.
.

Today and tomorrow:  Severe weather is not anticipated.

Wednesday through Sunday:  Thunderstorms are likely Thursday afternoon and night.  Some could be severe.  Monitor updates.   The greatest risk may end up over southern Illinois and western Kentucky.

Lightning is possible Saturday night and Sunday.  We may remain on the cool side of that system.  If that happens then the risk of lightning will be reduced.  At this time, severe weather appears unlikely.

Forecast discussion.

A nice day on tap for the region.  No weather concerns today, tonight, or tomorrow!  It will be mild today with widespread 70’s.  A bit cooler tonight with lows in the 40’s.  Warm on Wednesday with highs again in the 70’s.  Loving this weather.

Our next weather maker will deliver a blizzard to the Northern Plains.  You will be hearing about it on the news.  Thankfully, we will be on the warm side of this event.

Moisture, from the Gulf of Mexico, will struggle to return to our region.  Our previous system is pushing the higher dew points well southward.

Here is the forecast dew point numbers early Tuesday morning.  Notice the higher numbers are well to our south.

Also, notice the numbers being pulled into Nebraska.  That is an indication of our next storm system.

The low will pull moisture northward.  Low pressure rotates counter-clockwise.

.

Now, let’s look at Thursday at 7 PM.

See the stream of higher numbers in our region?  The models waffle on the exact numbers.  Sometimes they show upper 50’s to lower 60’s.  Other times they show lower to middle 50’s.

It is a thin river of deeper moisture.  Perhaps, just enough to help produce a band of thunderstorms ahead of the cold front.

.

Without a lot of time for recovery, there remain questions about the extent of shower and thunderstorm activity locally from the incoming system (arriving on Thursday afternoon/night).

Dew points will struggle to reach the upper 50’s or lower 60’s.  For severe weather, I like to see at least 58-degree dew points.

If we have enough moisture then the cold front will support a band showers and thunderstorms along and ahead of it.

Wind fields aloft will be strong.  This will be in response to an unusually deep area of low pressure well to our north and northwest.

Gradient winds (caused by low and high pressure) will be strong and gusty from Wednesday night into Thursday night.  As a matter of fact, winds on Thursday near the front should gust above 35 mph.  I would not be surprised if there were some gusts about 45 mph.

What moisture does pool ahead of the cold front will set the stage for a narrow band of showers and thunderstorms Thursday afternoon and night.

Some of the thunderstorms could produce small hail, damaging wind gusts, and even isolated tornadoes.

Overall, this is another conditional severe weather event.

What does conditional mean?  It means that some of the severe weather ingredients are marginal.  If those ingredients don’t come together then the risk of severe thunderstorms is lower.

If dew points can reach the upper 50’s and lower 60’s then the risk of severe storms will increase.

For now, we need to monitor trends.

I am forecasting a line of showers and thunderstorms to form in the region and then rapidly move east/northeast at speeds of 55 mph or greater.  Some storms could be severe.

It is possible the line forms right over us.  That could mean some areas experience no precipitation.  The further west you travel the greater the odds of nothing happening.  Monitor updates moving forward.

It will turn much colder behind the front.

Lows Friday morning will be mostly in the 40’s.  Lows Saturday morning will drop into the upper 30’s to lower 40’s.  Hopefully, we can avoid another frost.  We should be just warm enough for any significant issues.

Our next storm system arrives with showers and perhaps thundershowers on Saturday night and Sunday.  The low should track to our southeast.  If that happens then there will not be any severe weather concerns.

We still have some time to iron out the details of that system.

Model Future-cast Radars.  What the models believe the radar may look like.

.

The main concern continues to be another cold front on Thursday afternoon/Thursday night.  Then, another system Saturday night/Sunday.

Let me show you a few model future-cast radar animations.

This is the GFS model guidance animation.  This is the Thursday event.  This is a strong cold front.  Wind shear will be strong.  Instability may be lacking.  The wind shear could make up the difference.  Strong storms are possible.  Let’s keep an eye on it.

Timestamp upper left.

.

Here is the NAM model guidance.  Another model.

Notice both the GFS and the NAM quickly develop a line of thunderstorms over our local area.  Not everyone, however, receives rain.

This will be a narrow band of showers and storms that cross portions of the region.

Damaging wind is the main concern.

Some models show no precipitation for some of my forecast counties.

Timestamp upper left.

.

And here is the upcoming weekend event on the GFS.

This system moves up from the Gulf of Mexico.  That means it could have quite a bit of moisture with it.

This event is still several days away.  I will be monitoring trends in guidance.  Moderate rain is possible if the low tracks over our region.

Severe weather appears unlikely with it.

The EC model holds rain off until Sunday morning.  The GFS model is a bit faster with the rain arrival time.

The exact timing will need to be ironed out.

WeatherBrains Episode 689
.

Tonight’s WeatherBrains is a special show regarding the NWS’s Hazard Simplification Program or “Haz Simp”.  This program has been around for a couple of years and is designed to potentially redesign and reinvigorate the National Weather Service Watch/Warning/Advisory system.

Our Guest WeatherBrain this week is a Social Science Researcher and Project Manager for Haz Simp along with Eli Jacks of the NWS.  Her background is in meteorology, but her PhD program is interdisciplinary with a focus on sociology of disasters and risk communication.  Danielle Nagele, welcome to WeatherBrains!

Guest Panelist this week is soon-to-be graduating meteorology student from the University of Oklahoma.  Jordan Overton, welcome to the show!

Other discussions in this weekly podcast include topics like:

  • Are “certain death” messages counter-productive?
  • Why can’t the general public find their house on a map?
  • Kim’s analysis on the March 3rd, 2019 F4 tornado in Lee County AL
  • The Astronomy Report from Tony Rice
  • and more!
