In assessing the risk of severe storms the Storm Prediction Center (SPC) has three general risk levels: SLGT (slight), MDT (moderate), and HIGH.
A location within a region that is under a moderate risk has at least a 45% chance of having a severe thunderstorm come within 25 miles or a 15% or greater chance of a tornado coming within 25 miles. This usually indicates a significant severe weather event will take place.
A severe thunderstorm is a thunderstorm that produces at least one of the following:
- Winds to at least 58 mph
- Hail to 1 inch diameter or greater
- A tornado
What else can I help you with?
Could the SPC downgrade the MDT Risk of severe thunder storms tomore March 2 to a slight Risk?
They could downgrade it, but it is unlikely that they will.
Could the SPC downgrade the MDT Risk of severe thunder storms to slight?
Yes, the Storm Prediction Center (SPC) could downgrade the Moderate Risk (MDT) of severe thunderstorms to a Slight Risk if new data or analysis suggests a reduced threat of severe weather. This decision is based on ongoing monitoring of atmospheric conditions and the latest forecast models.
What Does A Slight Risk of severe Storms Mean?

How rare is a severe thunder storm watch in a MDT risk?
A severe thunderstorm watch is issued by the Storm Prediction Center when conditions are favorable for the development of severe thunderstorms, including the possibility of large hail and damaging winds. The likelihood of a severe thunderstorm watch being issued in a Moderate Risk (MDT) area will depend on various factors such as atmospheric instability, wind shear, and moisture levels. While a severe thunderstorm watch may not be extremely rare in a MDT risk area, it is still considered a significant event warranting attention from residents and authorities.
Why is there a MDT Risk of sever storms tomorrow March 2 2012?
As of March 1, 2011 a developing storm system is moving across the central United States. It will bring a cold front across the eastern United States into conditions that are ripe for producing thunderstorms. The wind shear (the amount that the wind speed and direction changes with altitude) is going to produce rotation in these storms, making it very likely that tornadoes, some of them strong, will occur.
Could the SPC downgrade the MDT Risk of severe thunder storms tomore March 2 to a slight Risk?
They could downgrade it, but it is unlikely that they will.
How come A MDT Risk for severe storms is lower for tornadoes than wind or hail?
That is most likely because tornadoes are less common than severe wind or hail, but more dangerous.
Could the SPC downgrade the MDT Risk of severe thunder storms to slight?
Yes, the Storm Prediction Center (SPC) could downgrade the Moderate Risk (MDT) of severe thunderstorms to a Slight Risk if new data or analysis suggests a reduced threat of severe weather. This decision is based on ongoing monitoring of atmospheric conditions and the latest forecast models.
Will the MDT risk for severe storms might or maybe be upgraded to high risk on Christmas day 2012?
Given that the area under a moderate risk is fairly small it is not likely that it will be upgraded to a high risk. Though, to be on the safe side it should not be ruled out. However, even without a high risk the will likely be a significant severe weather event.

What should you do if you're under a MDT risk of severe storms?
If a moderate risk of severe storms is issued for your area you should be on alert for any severe thunderstorm or tornado warnings. For these purposes you may tune into the TV or radio or check out the National Weather Service web site (link below). It is also a good idea to keep a battery operated weather radio handy as severe thunderstorms and tornadoes can cause power outages.
Is there potential for an MDT or high risk day of severe thunder storms on Monday Oct 13th 2014?
Given the large area under a 30% level of risk, a moderate risk cannot be ruled out. High risk outlooks are extremely rare in October. Only 3 have been issued in the past 30 years.
How rare is a severe thunder storm watch in a MDT risk?
A severe thunderstorm watch is issued by the Storm Prediction Center when conditions are favorable for the development of severe thunderstorms, including the possibility of large hail and damaging winds. The likelihood of a severe thunderstorm watch being issued in a Moderate Risk (MDT) area will depend on various factors such as atmospheric instability, wind shear, and moisture levels. While a severe thunderstorm watch may not be extremely rare in a MDT risk area, it is still considered a significant event warranting attention from residents and authorities.
Is there a risk for western NC to be under a MDT risk for severe thunder storms on Tuesday April 29th 2014?
It is too early to tell for sure as not outlook as yet been issued for that date. The Storm Prediction Center notes that a slight risk outlook may be issued. But consideration of a moderate risk outlook requires a level of confidence not possible with out current forecasting abilities.
Is there going to be a mdt risk for severe thunder storms this weekend April 26-27th 2014?
At this point it is much too early to tell. The fact that day 6 and day 7 outlooks have been issued means there is a good chance for severe weather, but such outlooks are not issued with any great degree of certainty. The outlook is based largely on "reasonable consistency" in what the forecast models indicate, but these models can be wrong.
Why did the SPC upgrade the MDT risk to high today March 2 2012?
As March 2 came around the SPC was able to provide a better prediction of the severe weather threat, a look at the wind shear and instability in the atmosphere indicated a high risk of tornadoes.
Why is there a MDT Risk of sever storms on the day 3 outlook of the SPC for this Saturday April 14 2012?
A strong low pressure system will be moving over the central plains into an unstable atmosphere, which will lead to the formation of thunderstorms. Strong wind shear will turn many of these storms into supercells with the potential to produce strong tornadoes.
