GREAT BASIN THROUGH THE EARLY PART OF THE WEEK. THIS WILL CONTINUE
TO PUSH PACIFIC MOISTURE INTO THE STATE, WITH ANOTHER ROUND OF
SHOWERS POSSIBLE TONIGHT INTO MONDAY. SOME COLDER AIR WILL FILTER
SOUTH FROM CANADA, FOR A LITTLE LIGHT SNOW POSSIBLE ALONG THE
CANADIAN BORDER. AT THE SAME TIME, THUNDERSTORMS ARE POSSIBLE IN
THE SOUTHWEST AHEAD OF THE CALIFORNIA LOW.
THE NEXT UPPER TROUGH MOVES INTO THE NORTHERN ROCKIES ON WEDNESDAY
AND INTO THE PLAINS THROUGH FRIDAY. THIS WILL LEAD TO ANOTHER
ROUND OF SHOWERS, AND WITH COLDER AIR WITH THE TROUGH, SNOW IS
POSSIBLE ACROSS MUCH OF THE REGION WEDNESDAY NIGHT INTO THURSDAY,
PARTICULARLY FOR ELEVATED AREAS. CHANCES FOR AT LEAST 2" OF SNOW
AT THIS TIME ARE 20-40%.

MINOR CHANGES TO THE DAY 1 FORECAST WITH A SLIGHT INCREASE IN
TEMPERATURES AND WINDS FOR TODAY.
