Good morning, fellow weather enthusiasts.

I hope you had a nice week.  We have welcomed spring into the region.  I know many of you are happy about that.

Speaking of spring, we have the latest preliminary April outlook from the long-range forecast team.

NOAA released their spring flood outlook yesterday.  No surprises here.  Locally, my biggest concern is the Mississippi River.

This graphic indicates an above-normal risk of flooding during the spring months.

You can read more about their outlook at this link.  Click here.

.

No surprise based on soil moisture content.

.

Today will be dry across the region.  Quite a bit of sunshine.  Mild temperatures.  No complaints about today’s weather!

We will have a dry night, as well.

Temperatures tonight may briefly drop below freezing at a few locations.  Frost is also a possibility.  If you have sensitive plants then keep that in mind.

Saturday will be another nice day.  Quite a  bit of sunshine.  We may see an increase in high clouds during the PM hours.  No rain.

Rain chances begin to ramp up late Saturday night into Monday.

The greatest rain coverage will likely be Sunday night into early Monday.

A few non-severe thunderstorms are also possible.  Lightning would be the primary concern.

Rain totals won’t be all that heavy.  I am forecasting 0.30″ to 0.60″ with locally higher amounts in thunderstorms.

Winds will become gusty Sunday and Monday.  Wind gusts above 20 mph are possible.

We dry out Monday night into Thursday.

We may have to deal with a few spots dropping below freezing on Monday and Tuesday night.  Winds Monday night should be gusty enough to prevent frost.  A light freeze is, however, possible.

Temperatures being to moderate on Wednesday and that will take us into next weekend.

Another storm system is forecast to spread showers and thunderstorms back into the region by next Friday or Saturday.

You can see that system on the GFS model guidance.  This is for next Friday at 7 PM.

.

.

This one is for next Sunday evening.  The event may linger Friday into Monday.  A couple of waves of low pressure are possible.  Still a bit early for confidence levels to be all that great on the duration of the rain event.

.

.

Here is an animation of that event.

You can see the area of low pressure well to our north.   That places us in the warm sector of the storm.  Snow on the backside (blue).  Green is rain.

Fairly tight storm system.  That would mean gusty winds.

This run of the GFS shows one cold front that brings an end to the rain by Saturday morning.

The other run of the GFS lingers rain longer.  Again, a bit too soon for details.

Plan on at least a chance of showers next Friday and Saturday.  Hopefully, Sunday will be dry.

.

.

Have a super weekend!  Rain or shine.

 

Freeze conditions?

A light freeze is possible tonight (Friday).  Frost, as well.  Lows will range from 30 to 35.  Some sensitive plants may be impacted.

I have been monitoring Monday and Tuesday night for freeze conditions.

For now, it appears that 30’s are possible both night.  The coldest night will likely be Tuesday night.  The guidance has backed off widespread 20’s.  With that said, if you have concerns about freeze conditions then I would suggest monitoring updates.

Dry conditions Tuesday into Wednesday.

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

This is the NAM model guidance.

It does not go out as far as the GFS model (second animation below).

You can see the NAM brings some showers into the region late Saturday night and especially on Sunday.

It won’t be exact, but you get the general idea that rain showers will be increasing as we move deeper into the weekend.

.

.

Here is the GFS model guidance.  It goes out further in time.

These maps update several times a day.  Occasionally, in between updates, you may see a duplicate day or one out of sync.

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.
