DISCUSSION
A WEAK STORM SYSTEM WILL MOVE ACROSS THE STATE
OVERNIGHT THROUGH LATE TUESDAY. THIS WILL BRING ENOUGH MOISTURE
AND INSTABILITY FOR A FEW SHOWERS AND THUNDERSTORMS IN THE
VICINITY OF THE BURN SITE DURING THE MID TO LATE AFTERNOON. THE
CHANCE OF WETTING RAIN WILL BE VERY LOW, BUT ANY STORMS THAT
DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE GUSTY AND ERRATIC
THUNDERSTORM WINDS. A BIT OF INSTABILITY WILL LINGER INTO
WEDNESDAY, BUT THE CHANCE OF A STORM IMPACTING THE FIRE ON THAT
DAY IS LESS THAN 10 PERCENT. OTHERWISE, VERY MILD CONDITIONS WILL
CONTINUE THROUGH SATURDAY WITH GENERALLY LIGHT AND TERRAIN DRIVEN
WINDS. CONDITIONS WILL BE DRY THURSDAY THROUGH SATURDAY. IT IS
LOOKING INCREASINGLY LIKELY THAT A PACIFIC NORTHWEST STORM SYSTEM
WILL BRING A STRONG COLD FRONT THROUGH AT LEAST NORTHERN UTAH
SUNDAY INTO MONDAY, BRINGING MUCH COOLER TEMPERATURES. WINDS COULD
BECOME QUITE GUSTY AHEAD OF THIS FRONT IN THE VICINITY OF THE BURN
SITE SUNDAY AFTERNOON, WITH SOME GUIDANCE INDICATING WIND GUSTS TO
40 MPH. THE AMOUNT OF PRECIPITATION ASSOCIATED WITH THIS SYSTEM IS
MUCH MORE UNCERTAIN AT THIS TIME, WITH SOME GUIDANCE SHOWING
TROPICAL MOISTURE ACCOMPANYING THE SYSTEM AND OTHERS SHOWING
LITTLE IN THE WAY OF MOISTURE WITH THE SYSTEM.
