FRONT, THE WIDESPREAD VFR CONDITIONS CURRENTLY BEING OBSERVED IN
THE AREA WILL GRADUALLY DETERIORATE TO MVFR AND LIKELY IFR
VISIBILITIES AND CEILINGS LATE TONIGHT THROUGH MUCH OF TUESDAY.
TONIGHT, LACK OF INSTABILITY SHOULD PREVENT THUNDER OCCURRING SO
REMOVED IT FROM THE FORECAST WITH THIS UPDATE, BUT WILL CONTINUE
TO MONITOR TRENDS IN SHOWER DEVELOPMENT. THE BETTER POTENTIAL
FOR THUNDER WILL OCCUR THIS AFTERNOON INTO THE EVENING WHEN
ENHANCED FORCING FROM THE FRONT CREATES A MORE UNSTABLE
ATMOSPHERE. NOT EXPECTING THIS THUNDER TO BE WIDESPREAD SO
HANDLED ANY MENTION WITH A TEMPO. NEAR THE END OF THE TAF
PERIOD, CONDITIONS WILL BEGIN TO IMPROVE BACK TO VFR FOR THE FAR
WESTERN TERMINALS, WHICH WILL GRADUALLY PUSH EAST AFTER THIS TAF
PERIOD.
