I am trying to understand exactly when our risk is enhanced for severe weather in NC. Now we are placed in a slight risk of severe weather on Wednesday. I am trying to understand what differentiates the risk for damaging wind event, tornadoes or hail event here in NC.
Here's what maps I am looking at.
NAM Model Extraction to look for SFC CAPE, LI, Dewpoint, Air Temp. http://68.226.77.253/text/meso/NAM_KGSO.txt
60 HRs OUT:
Air Temp: 60.1 F
Dewpoint Temp: 58.3 F
CAPE: 310.7 J/Kg
3 HR Precip: 0.10 inches
LI: -2.1 C
SWEAT: 312.8
SI: -0.7
0-3km Hel(J/kg): 328.6
SFC Pressure/SLP Pressure/1000-500 mb thickness NAM: http://weather.unisys.com/nam/nam.php?plot=pres&inv=0&t=60 I clearly see a cold front but I dont know besides that to interpret from this map.
SFC Temp/ Convergence/Dewpoint/Wind NAM: http://weather.unisys.com/nam/60h/nam_sfc_60h.gif I dont know what to look for in this map.
850 mb NAM Forecast: http://weather.unisys.com/nam/60h/nam_850_60h.gif I look for strong low level jet.
700 mb NAM Forecast: http://weather.unisys.com/nam/60h/nam_700_60h.gif I obviously look for positive Vertical velocities but besides that dont know what else to look for here.
500 mb NAM Forecast: http://weather.unisys.com/nam/60h/nam_500_60h.gif If Voriticity stay to the north of you area does that decrease the chance of seeing severe weather such as damaging winds, hail, or tornadoes?
300 mb NAM Forecast: http://weather.unisys.com/nam/60h/nam_300_60h.gif All I look here for is strong low level jet and that I should be in the left exit region of the jet streak? But the problem I have is what should I look for if I want to see damaging wind event, hail or even tornadoes?
Also what are the dewpoint, MUCAPE, Mid-Level Lapse rates (SPC Mesoanalysis), SFC Lapse Rates (SPC Mesoanalysis) requirements for seeing damaging wind event, tornadoes or hail in NC! Feel free to suggest me other website I can look for since I am amateur at this.
Thanks a lot! Hope to talk to you soon!
