August 10th and 11th: Rain chances.

Friday morning update

Thunderstorms are likely today.  A few of storms could be intense with high winds.  Most storms will remain below severe levels.  Low end risk for damaging winds.

Locally heavy rain will occur under the thunderstorms.  Some areas could pick up 1/2 to 1″ of rain per 30 minutes.

It now appears both Saturday and Sunday will remain dry.  This is a change from previous forecasts.  Thunderstorm chances may increase Sunday night and Monday as a warm front moves northward from Tennessee.

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.

Thursday night through Monday:  Severe weather is not anticipated.

We will have thunderstorms in the forecast, but the severe weather risk is low.  Lightning will be the main concern.  A couple of storms could produce high winds, but the overall risk is low.

If stronger storms were to occur they would most likely be on Friday and again on Sunday.

 

beausanalysis

A fairly active weather pattern over the coming days.  Plenty to monitor.

A few showers and thunderstorms will be possible this evening and tonight.  The best chance would be over northern parts of southeast Missouri and a sliver of southwest Illinois.  Majority of the region will have lower rain chances and should remain dry.

Looking ahead

We have a few weak disturbances to monitor over the coming days.  Each will deliver rain and thunderstorm chances.  The problem is timing and coverage.

I have two peak time periods for showers and thunderstorms.  One of those will be Friday and the other will be Sunday.

This has not been an easy forecast.  At one time Saturday appeared to be a widespread rain event.  Now, guidance is showing sunshine.  This is one reason I have been telling everyone to check back frequently for updates.

Confidence is lower than normal in the overall forecast.  Timing these weak disturbances is tricky.  Even trickier is how much rain coverage to paint on the weather map.

For now, I have kept rain probabilities fairly low for tonight, Friday night, Saturday, and Saturday night.  That would mean 30% or less. 
 
I have decent precipitation chances for Friday and Sunday.

We do need rain.  Much of the region is and has been drier than normal for the past four to six weeks.  Yes, some of you have experienced decent rain, but many have not.

Here is the updated drought monitor map (click to enlarge)

and

I have been telling everyone to keep checking back, because confidence on the weekend details has been low.
 

I did make some adjustments this morning (esp for Saturday). I was thinking today is when confidence would grow (as far as the details).

There might be a bit of a temperature range Saturday.  This will depend on the placement of the frontal boundary.

Forecast lows for Saturday morning.

 
Saturday may end up fairly nice with quite a bit of sunshine. If there were to be thunderstorms on Saturday, they would most likely be over the Missouri Bootheel into northwest Tennessee.  Smaller chances (a non-zero chance) north of there along the KY/TN border. Right now, if everything holds, the forecast should be okay.

Hurricane Franklin will continue to push into Mexico over the coming days.  It appears that the moisture for Franklin will remain to our south and southwest.  Occasionally, systems like this will push moisture into our region.  It appears that is unlikely with Franklin.

Here are the updated six to ten day temperature and precipitation probability maps.

What is the percentage chance of them averaging normal, below normal, or above normal.

Six to ten day temperature outlook for Tuesday, August 15th through Saturday, August 19th

As you can see, probabilities favor below normal temperatures and above normal precipitation.

Six to ten day precipitation outlook for Tuesday, August 15th through Saturday, August 19th

Eight to fourteen day temperature outlook for Saturday, August 19th through Wednesday, August 23rd

Eight to fourteen day precipitation outlook for Saturday, August 19th through Wednesday, August 23rd

Eclipse Weather

Ensembles are showing rain and clouds for the eclipse.  It is still way too early for a real forecast, but I don’t like the ensembles.  They would indicate poor viewing conditions.  Let’s hope they are wrong.

This is the same model, but run with slightly different beginning parameters.  The goal is to see how many of the panels agree.  Large agreement raises confidence in the forecast.  We are pushing the envelop for extended range.  PLENTY of days to monitor.  Plenty of days for adjustments.  Confidence in the forecast probably won’t rise until next Thursday.

The EC guidance is drier than the GFS guidance.  Battle of the models.  Long way off, still.

Right now, the yellow boxes indicate a model run that shows clouds and rain.  Obviously, this is not great news.  The good news, however, is that we still have many days left for adjustments and changes.

Fingers crossed.

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.

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
