Wind forecast

 

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.

Saturday through Wednesday:  I am watching Sunday and Sunday night.  Hail is possible.  A few severe storms.

Have there been any changes in the forecast over the last 24 hours?

I had to decrease temperatures today and tonight.  I also shaved a few degrees off Friday night’s low temperatures.

I lowered Sunday’s temperatures because of rain and clouds.

A light freeze is possible Friday night.

 

Does the forecast require action?

Yes.  Avoid flooded roadways.  Many rivers are flooding.

Forecast discussion.

Note:  Major river flooding continues in some areas.  The Mississippi River continues to rise.  Be sure and check out the latest crest forecast numbers.  There may be more than one crest.
.
The region picked up 0.05″ to 0.20″ of precipitation over the last 24 hours.  A few spots picked up a bit more.

It has been a wet year, thus far.

Here are the year to date rainfall totals.

.

Let’s look at the anomaly map.

Widespread well above normal rainfall has occurred over the Eastern United States.

This is one reason rivers are flooding.

.

For good measure, here is the month to date temperature anomaly map, as well.

We have been cooler than normal, thus far.

.

A cold front has been moving through the region over the last 24 hours.

You can see that front here on the morning weather map.

 

That will leave us with a mix of sun and clouds today.

Clouds will linger over southeast Illinois into the eastern half of western Kentucky.  Elsewhere, we should see a mix of sun and clouds.  Temperatures will be slightly below normal today across most of the area.  Nothing extreme.  Fairly typical March day.  The second day of spring!

There will be a large range of temperatures today.  Where clouds remain thick you can expect highs mostly in the 40’s.  Elsewhere, highs in the 50’s will occur.  A cool day, overall.

A chilly night ahead of us.  Widespread 33 to 36-degree readings for the region.  It does appear most areas will remain above freezing tonight.

Dry weather will be with us through Saturday.  That is good news.

At one point it appeared that widespread 60’s would be in the cards on Friday and Sunday.  I had to shave some degrees off the forecast highs both days.

Friday will deliver widespread middle to upper 50’s over southeast Illinois and northwest Kentucky.  Meanwhile, most of southeast Missouri, southwest Illinois, western Kentucky, and northwest Tennessee should climb into the upper 50’s to middle 60’s.  The middle 60’s would likely remain closer to the Poplar Bluff area.

We should have quite a bit of sunshine on Friday, as well.  It will feel warmer with the March sun angle.

Friday night will be cold.  Those with sensitive plants might want to monitor the temperature forecast.  I am forecasting widespread 30 to 35 degrees.  A few of the favored cold spots could dip into the 28 to 30-degree range.  That would most likely be over southern Illinois (further north you travel the better chance of the upper 20’s) and northwest Kentucky closer to the Evansville, Indiana area.

Saturday will deliver some sun and widespread upper 50’s to around 60 degrees.  Some high clouds will be noted moving in from the west during the afternoon and evening hours.  These clouds will thicken Saturday night.

A new weather system approaches the region on Sunday and Monday.  This system is forecast to bring additional rain chances to the region.  This event may be a bit heavier than the previous one.  Some storms could be severe.

You can see that system on the Saturday morning weather map.  We will likely remain dry during the daylight hours on Saturday.

 

 

A few thunderstorms will be possible Sunday afternoon into early Monday morning.  Lightning would be the primary concern.  Hail is another concern.  Lower risk for damaging winds and tornadoes.

Plan on 40% to 60% rain chances Sunday, Sunday night, Monday, and Monday night.  The rain will end west to east Monday night.

There will be a colder surge of air Monday night that could briefly change the rain to a rain/snow mix.  No concerns for accumulating snow.

I did shave a few degrees off of Sunday’s highs because of clouds and rain.

Saturday will be the pick day of the weekend.

.

Freeze conditions?

I have been monitoring Monday and Tuesday night for freeze conditions.  The GFS model guidance has been the coldest with this event.  It has a cold bias.

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.

Some areas will likely dip below freezing on at least Tuesday night.

Dry conditions Tuesday into Wednesday.

Another chance of rain around March 28th/29th.

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.

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.
