May 11th and 12th, 2017: Thunderstorm chances.

Friday update
.
May 12, 2017: Flash flood warnings, severe thunderstorm watches, and severe thunderstorm warnings were issued yesterday for portions of the region, but today will be a calmer and cooler day. Still a bit damp, for some.
 
Friday morning:
 
Rainfall totals overnight ranged from a trace to more than three inches. As is typically the case with thunderstorms, some areas received a lot more than others.
 
An upper level low will be positioned near the region today. As our storm system, that produced the heavy storms, pulls away from the area, we will be left with some remaining showers. Small chance for lightning this morning. No severe weather concerns.
 
It will be noticeably cooler today with highs from 68 to 74. most of the region was in the 80’s yesterday.
 
This afternoon:
 
Showers will slowly end from west to east as the day wears on. Based on radar and other observations, it might take a little while for all of the showers to end. We do have precipitation along the front back into southern Missouri and Arkansas.
 
There remains some debate about how quickly the precipitation will end this afternoon and what the coverage will look like.
 
The Hrrr model lingers showers in our area until evening. Keep that in mind. I certainly can’t rule that out. Coverage would be on the decrease.
 
Tonight through Sunday night:
 
We dry out tonight. We will remain dry through Tuesday.
 
Highs on Saturday will rise into the 70’s.
Highs on Mother’s Day will rise into the upper 70’s to lower 80’s
Highs on Monday and Tuesday will rise into the 80’s.
 
There is the possibility of unsettled weather as we move into Wednesday through next week. Perhaps a few rounds of precipitation. Confidence is low on the details.

An explanation of what is happening in the atmosphere over the coming day

2014-11-24_13-38-04

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: We will have thunderstorms along a frontal boundary that will be moving southward through the region.   Some of the storms could produce hail, damaging winds, and frequent lightning.  The tornado risk is low.  Monitor updates in case watches and warnings are issued.  I will be sending out text messages.  You can sign up for those messages at www.beaudodsonweather.com

Friday into Tuesday:  Severe weather is not anticipated.  There is a small risk for lightning on Friday.

Wednesday through Friday:  Monitor updates.  Thunderstorms will again appear in the forecast.

Weather Analysis for the coming week:

We still have rivers out of their banks across most of the region.  Be sure and check out the latest lake and river stages.  Here is the link to view those ~ River Stage Forecasts

The big weather story, in the short term, will be the ongoing shower and thunderstorm activity.  A frontal boundary is slipping southward through the area, as of this writing.

The front will sag southward on Thursday evening and night.  Showers and thunderstorms will accompany the front.  Some of the storms could be intense with frequent lightning, hail, and strong wind gusts.  Locally heavy rain, as well.

An area of low pressure will pass to our south Thursday night and Friday.  There will be some showers north of the low.  This will keep rain chances over at least the southern two-thirds of the region into Friday morning.  This will also mean cooler temperatures on Friday.  You can expect highs to remain mostly in the 60’s.

There remain some questions on coverage of precipitation on Friday morning.  Quite a bit of guidance indicates scattered rain.  Perhaps we will have more dry than wet before 12 pm Friday.  Hopefully that will be the case.  I know many of you have outdoor events on Friday.

Showers should end from west to east by Friday afternoon and evening.  Precipitation will first end over southeast Missouri and will linger longest of the Pennyrile area of western Kentucky.

Friday night through Sunday night:

Cooler temperatures are anticipated for Friday, Friday night, and Saturday.  You can expect highs into the lower to middle 70’s on Saturday with plenty of sunshine.  Highs by Sunday should  reach into the upper 70’s and perhaps some 80’s.

You can see the temperature map here

Saturday highs

Sunday highs

Monday and Tuesday should remain dry.

An unsettled weather pattern returns Wednesday through at least Friday.  Periods of thunderstorms will be possible.  We will need to monitor for strong storms.  Still a bit early to make a call on the details.  Signals for unsettled weather are in the charts.

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.

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
