DISCUSSION
MOISTURE REMAINS IN PLACE OVER THE REGION TODAY, BRINGING
ANOTHER DAY OF SHOWER AND THUNDERSTORM ACTIVITY OVER THE HIGH
TERRAIN. BOULDER MOUNTAIN WILL REMAIN THE HOTSPOT FOR SHOWERS AND
THUNDERSTORMS TO BEGIN DEVELOPING AFTER 1100, WITH STORMS FAVORING
A SOUTHWEST PROGRESSION AFTER FORMING OVER THE HIGH PLATEAU.
WHILE A MAJORITY OF STORMS ARE ANTICIPATED TO PASS TO THE NORTH
AND WEST OF THE FIRE AREA, THERE WILL STILL BE AN ENHANCED RISK OF
FREQUENT LIGHTNING STRIKES AROUND THE FIRE AREA, LIKELY STRIKING
OUTSIDE THE CORE OF THE STORM. ANY STORMS THAT DO END UP MOVING
OVER THE FIRE AREA WILL LIKELY BRING MODERATE TO HEAVY RAINFALL.
GUSTY OUTFLOW WINDS ARE EXPECTED THIS AFTERNOON AS STORMS FORM
OVER THE HIGH PLATEAU AND DRIFT SLOWLY OFF THE TERRAIN, WITH THE
MOST LIKELY OUTFLOW WIND DIRECTION COMING FROM THE NORTHWEST.
SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED TO CONTINUE UNTIL
AROUND 2000, HOWEVER, THERE WILL STILL BE A LOW (30-40%) CHANCE
FOR SHOWERS TO MOVE OVER THE FIRE OVERNIGHT.
