-- Changed Discussion --
PREVIOUS FORECAST DISCUSSION IS ON TRACK. EARLY MORNING CLOUD COVER EXPECTED TO SLOWLY DECREASE THROUGH THE AFTERNOON. TODAYS CONVECTION STILL LOOKS TO BE ISOLATED AND SCATTERED DUE TO NO FOCUSED LIFTING MECHANISM...THEY SHOULD BE DIURNAL IN NATURE AS WE DESTABILIZE THIS AFTERNOON. SOUNDINGS STILL SHOWING STEEP LAPSE RATES AND ROUGHLY 2000 J/KG CAPE LATER TODAY. THE NAM SOUNDING SHOWS SOME CAPPING IN PLACE AT AROUND 700MB BY THIS AFTERNOON...WHILE THE GFS SHOWS SOMEWHAT OF AN ISOTHERMAL PROFILE FROM ABOUT 800MB UP TO 700MB. SO IT WILL BE INTERESTING TO SEE IF STORMS DO DEVELOP. BUT ONCE AGAIN...IF THEY DO THE COVERAGE SHULDN`T BE WIDESPREAD. NO CHANGES OR UPDATES TO CURRENT FORECAST.
