The 20Z run is the latest available data and the ongoing storms (as of 2230Z) are depicted to be in a decent region of surface CAPE (&gt;2000 J\/kg), practically no CIN, and high pockets of surface and 2-5km instantaneous updraft helicity on the front edge of the broken line of convection. When I analyzed the LAPS&#8217; max base reflectivity product and compared it with real-time MRMS composite reflectivity, it does okay in the 2.5-hour forecast in depicting a general region of convection stretching from east-central Illinois ESE toward the IN\/OH\/KY borders. The model is spatially displaced slightly but at least captures the general overview of the current setup.<\/p>\n<p><a href=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-9094\" alt=\"2230Z_LAPS_maxref\" src=\"http:\/\/hwt.nssl.noaa.gov\/ewp\/internal\/blog\/wp-content\/uploads\/2014\/05\/2230Z_LAPS_maxref-1024x544.png\" width=\"584\" height=\"310\" srcset=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref-1024x544.png 1024w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref-300x159.png 300w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref-768x408.png 768w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref-500x266.png 500w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_LAPS_maxref.png 1701w\" sizes=\"auto, (max-width: 767px) 100vw, (max-width: 1200px) 60vw, 720px\" \/><\/a><a href=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/2230Z_MRMS_compref.png\"><img loading=\"lazy\" decoding=\"async\" alt=\"2230Z_MRMS_compref\" src=\"http:\/\/hwt.nssl.noaa.gov\/ewp\/internal\/blog\/wp-content\/uploads\/2014\/05\/2230Z_MRMS_compref-1024x544.png\" width=\"584\" height=\"310\" \/><\/a><\/p>\n<p>Moving forward to the 4-hour forecast (00Z), LAPS forecasts the following:<\/p>\n<p><a href=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-9096\" alt=\"00Z_LAPS_maxref\" src=\"http:\/\/hwt.nssl.noaa.gov\/ewp\/internal\/blog\/wp-content\/uploads\/2014\/05\/00Z_LAPS_maxref-1024x544.png\" width=\"584\" height=\"310\" srcset=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref-1024x544.png 1024w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref-300x159.png 300w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref-768x408.png 768w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref-500x266.png 500w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2014\/05\/00Z_LAPS_maxref.png 1701w\" sizes=\"auto, (max-width: 767px) 100vw, (max-width: 1200px) 60vw, 720px\" \/><\/a><\/p>\n<p>If LAPS data is to be used to enhance near-term mesoscale forecasting, I personally would like to see some additional fields, such as wind, etc.<\/p>\n<p>~Linda<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Attempting to give a mesoscale environment update for my warning partner, I pulled up all of the LAPS products available in the 800&#215;800 domain.
