ISOLATED THUNDERSTORM CHANCES LATE THIS AFTERNOON AND THROUGH WEDNESDAY.
RECENT MODEL TRENDS HAVE SLOWED THE ARRIVAL TIME OF PRECIPITATION TO
THE BURN SITE UNTIL AROUND 2-4PM, HEAVIEST PRECIPITATION LATER TONIGHT
AND INTO TOMORROW MORNING. OVERALL RAINFALL TOTALS FROM THIS SYSTEM
LOOK TO BE AROUND 1.00 INCH OR SO, HIGHER IF A T-STORM DEVELOPS OVER
THE SITE. WE WILL DRY OUT BY THURSDAY AND FRIDAY, THEN BY SATURDAY
AFTERNOON A COLDER AND WETTER WEATHER SYSTEM WILL BRING WIDESPREAD RAIN
LOWER ELEVATION SNOW CHANCES INTO AT LEAST EARLY NEXT WEEK, WITH THE
POSSIBILITY OF ACTIVITY CONTINUING THROUGH THE MIDDLE OF THE WEEK.
SNOW LEVELS FOR THIS SYSTEM MOVING IN TODAY ARE GOING TO BE 6000
FEET AND ABOVE, DROPPING SLOWLY TO AROUND 5000-6000 FEET WEDNESDAY
AFTERNOON. MOST OF THE HEAVIER SNOW SHOWERS SHOULD BE OUT OF THE
