Severe Weather Outlook for July 1st 2012 ..Once again the temperatures across the outlook area are going to be on the warm to Hot side ..temperatures will be in the 80 to in the 100's range... So if you are out and about make sure you drink plenty of fluids.. http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F18_TMPF_2_M_ABOVE_GROUND.png .. In addition to the hot temperatures dew points will be in the 60s to 70s so it will feel hotter then it actually is.. http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_DPTF_2_M_ABOVE_GROUND.png .. Convective Potential Energy or CAPE is going to be from 500-4000 depending on where you are located.. http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_CAPE_SURFACE.png.. LIFT Index will be from 0 to about negative 10 depending on where you are located .. http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_PLI_30_0_MB_ABOVE_GROUND.png.. SHEAR is decent with 30 knots to around 50 knots .. http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_SHRM_500_MB.png .. ENERGY HELICITY INDEX is at 1 or above ..essentially the zone to watch would be from Indiana back towards Montana on a NW tracking..http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_EHI_3000_M.png .. However HELICITY is not all that impressive across the region..http://www.twisterdata.com/data/models/nam/221/maps/2012/07/01/00/NAM_221_2012070100_F24_HLCY_3000_M_ABOVE_GROUND_0_M_ABOVE_GROUND.png ... We are going to place a 2% for tornados in the severe zone basically from Indiana NW tracking back into Montana.. At the surface ...http://www.hpc.ncep.noaa.gov/basicwx/91fwbgus.gif we essentially have a quasi stationary front... and this front along with impulses of energy moving across will serve as the trigger for the severe weather potential...
