48-hour forecast
.
.
Tuesday to Tuesday
1. Is lightning in the forecast? Yes. Lightning is possible Monday night into Wednesday.
2. Are severe thunderstorms in the forecast? Unlikely. A few storms could be intense over western Tennessee later this afternoon. A line of storms may push into the area from Arkansas. It would be moving northeast into western Tennessee and perhaps south-central Kentucky. The overall severe weather risk appears to be low. I will keep an eye on it.
The NWS officially defines a severe thunderstorm as a storm with 58 mph wind or greater, 1″ hail or larger, and/or tornadoes
3. Is flash flooding in the forecast? Low risk. Locally heavy rain is possible Tuesday. Some nuisance flooding is possible.
4. Will the wind chill dip below 10 degrees? No.
5. Is measurable snow or ice in the forecast? No.
6. Will the heat index top 100 degrees? No.

Today through March 26th: There is a low end risk of a severe thunderstorm across northwest Tennessee later this afternoon as a line of storms pushes across the region.
.
.
Today’s outlook (below).
Light green is where thunderstorms may occur but should be below severe levels.
Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.
One is the lowest risk. Five is the highest risk.
A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
The tan states are simply a region that SPC outlined on this particular map. Just ignore that.
The black outline is our local area.

Weather Discussion
-
- Showers and thunderstorms today and tonight. Locally heavy rain.
- A few remaining showers and thunderstorms Wednesday.
- Patchy light rain Wednesday night and Thursday (not much in the way of rain totals during this time-period).
- Chilly temperatures this week.

Forecast Discussion
Widespread showers and thunderstorms pushed into the region overnight.
Many of you woke up to a vivid lightning show between 12 AM and 3 AM.
Thankfully, all of the severe thunderstorms and tornadoes have remained to our south. Numerous tornadoes were reported last night in Texas. Several producing considerable damage.
We will have to deal with showers and thunderstorms today. There may be some heavy downpours today. All in all, the forecast is on track.
I am watching northwest Tennessee for a level one severe weather threat this afternoon. I believe the bulk of the severe weather will stay to our south.
A line of storms will push into the region this afternoon from Arkansas. It is those storms that could be intense.
Here is what radar looked like at 6 AM. That is snow on the back-end of the storm system (Kansas/Nebraska).
You can see the severe storms in Louisiana and eastern Texas, as well.
Today will be a raw day. Gusty winds, at times. Cool temperatures. Widespread rain.
Rain totals from start to finish of 0.8″ to 1.6″ is the going forecast. There will be locally higher totals.
Some nuisance flooding is possible. Ditches, small streams, and poor drainage areas.
Severe thunderstorms are likely today to our south. If you have friends in that area, then let them know.
The orange and red zone are the highest risk. The light green zone (in our region) is sub-severe storms (just lightning).
We are going to have shower and thunderstorm chances tonight into Wednesday. The coverage, however, won’t be as great as it is this morning and afternoon.
Some light showers are possible Wednesday night (isolated) and again Thursday.
Rain totals Wednesday into Thursday will be light (less than 0.20″).
Dry conditions Thursday night into Friday night.
I am watching an upper level low Friday night and Saturday. Model guidance is not in agreement on the exact track of this upper level low.
If it were to pass right over our region, then some scattered light showers would be the end result. It would also mean cooler conditions than the going forecast.
I will need to monitor trends concerning Saturday’s forecast. I did go ahead and place a slight chance of showers in the forecast.
You can see it on these model images.
The EC model is furthest west with it. That is the upper level low in red/orange.
The GFS model is slight further east/northeast
Hopefully, it will push further east and avoid our region.
It might be cold enough for a mixture of rain and snow/graupel underneath the upper level low across portions of the Ohio Valley.
Again, hopefully to our east!
Temperatures will be chilly this week and this upcoming weekend.
Saturday night should be the coldest night. Our northern counties might even flirt with the freezing mark.
A warming trend early next week. Spring is here.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.
What should I take from these?
- The general idea and not specifics. Models usually do well with the generalities.
- The time-stamp is located in the upper left corner.
.
What am I looking at?
You are looking at different models. Meteorologists use many different models to forecast the weather. All models are wrong. Some are more wrong than others. Meteorologists have to make a forecast based on the guidance/models.
I show you these so you can see what the different models are showing as far as precipitation. If most of the models agree, then the confidence in the final weather forecast increases.
