Forecast discussion.

Our well-advertised rain system is moving into the region this morning.  Rain showers will spread eastward through the day.

See the local interactive city-view radars to track the precipitation.  Link to the radars.

This is a quick-hitting system.  That is good news because it means the rain will not aggravate the flooding situation.  Thankfully.

No severe thunderstorms to deal with, either.  It sounds like a win-win.

Clouds will keep temperatures in the 50’s today.

Rain totals will likely remain below 0.25″ across most of the area.  There could be some patches of higher totals.  Not much higher.

The rain will spread off to the east as we move into the evening and overnight hours.  That will mean drying conditions locally.

The good news is that Thursday, Friday, and Saturday will be dry.  Calm weather.  A warming trend, as well.

Fine fishing weather all three of those days.

Check out the temperature forecast for Friday, Saturday, and Sunday.

Temperatures may be a bit higher than this on Friday and Saturday.

Sunday, unfortunately, will deliver increasing clouds and rain shower chances.

I continue to monitor the risk of thunderstorms.

Severe weather will be possible to our west with this system.  For now, however, locally it appears we may miss the severe weather.

If the storm track changes then the severe weather forecast will change.  Thus, monitor updates, as always.  This is the time of year to always monitor updates.

Conditions can change.

Models are showing colder weather behind our Sunday and Monday system.  The GFS was even showing snow in our area.  I don’t think that will happen but it does tell us that colder weather will follow on the backside of the area of low pressure.

Freeze conditions are possible next week.  Those with agricultural interests will want to monitor updates moving forward.

 

Friday highs (may need to bump these up a bit)

 

Saturday highs

 

Sunday hights will depend on cloud cover and rain.

Likely going to be widespread 50’s with a few 60’s possible.

 

Monday highs

Falling temperatures behind the cold front.

Check out these low-temperature forecast numbers.  We will need to monitor this.

Sometimes, the GFS data can be a tad too cold.  Either way, a freeze is possible.

Another chance of rain arrives by Sunday and Monday.  I may need to add thunderstorms to the forecast.  For now, the severe weather threat appears minimal.  As always, monitor updates.

VIDEO UPDATES

These are bonus videos and maps for subscribers. I bring these to you from the BAMwx team. I pay them to help with videos.

The Ohio and Missouri Valley videos cover most of our area. They do not have a specific Tennessee Valley forecast but they may add one in the future.

The long-range video is a bit technical. Over time, you can learn a lot about meteorology from the long range video.

NOTE: These are usually not updated on Saturday or Sunday unless there is active weather.

I bring the following long-range outlooks from the BAMwx team.  They are excellent long-range forecasters.  These are more detailed than the images above.

Remember, long-range outlooks are always going to be a lower confidence level than short-term forecasts.

Long-range forecasting is not an exact science. There are many variables that determine the eventual outcome of a long-range forecast.
