UPDATED SOME ZONES ALREADY THIS MORNING FOR A BIT STRONG WORDING FOR
THUNDERSTORMS.  MORNING SOUNDING VERY UNSTABLE BUT FOR THIS
AFTERNOON THERE WILL BE NO GOOD TRIGGER OTHER THAN AFTERNOON
HEATING.  THUNDERSTORM ACTIVITY THIS MORNING IS CENTERED AROUND A
VORT MAX AND THE NEW ETA MODEL MOVES THIS VORT MAX TO THE NORTH
NORTHEAST INTO THE NORTHERN ZONES BETWEEN 20Z AND 21Z.  THIS TIMING
ALSO NEAR MAX HEATING SO MAIN REASON FOR THE STRONGER WORDING IN
IDAHO ZONES 11 AND 13 AND OREGON ZONE 62.  REST OF THE ZONES LOOK
GOOD FOR TODAY AS SURFACE HEATING WILL HELP WITH THE THUNDERSTORM
ACTIVITY.  TONIGHT UPPER LEVEL LOW CONTINUES TO MOVE TO THE EAST
WITH ENOUGH DYNAMICS AHEAD OF THIS FOR CONTINUED THUNDERSTORM
ACTIVITY THROUGH THE NIGHT.  SHORT WAVE TO MOVE THROUGH THE STATE ON
MONDAY FOR DECREASING CHANCES OF SHOWERS AND THUNDERSTORMS THROUGH
THE DAY.  ALLEN

.BOI...NONE.
