Hit from all sides

We are really going to see every aspect of weather this week; the warm and the cold, snow, sleet, and severe weather. Wednesday will be a tale of two worlds across the state as the West prepares for more then six inches of snow and the east prepares for the possiblity of heavy rain and severe weather. The Storm Prediction Center issued a slight risk for severe weather. The reason for this is that many of the severe weather indicators will be very high. These are just some of the terms and the level at which they are expected with this storm;



Lifted Index= -1 to -5 (accounts for instability in the atmosphere)
Helicity= 200-500 (measurement for the amount of spin in the atmosphere a.k.a. tornados)
Precipitable water= >1" (measurement of the amount of moisture in the atmosphere)
CAPE= 500-1500 (measurement for potential energy a.k.a. how fast a thunderstorm can develop)

If you want some more information on what these indecies mean, you can go to google or wikipedia and they give you some pretty good information. Now, to sum up the figures I just showed, conditions are considered favorable for severe weather and all types of severe weather, including large hail, damaging winds, and tornados. So keep your eye to the sky across the east on your wednesday because it could get nasty. Here are the areas under a slight risk tomorrow courtesty of the Storm Prediction Center.


Stay safe tomorrow!
