...STRONG AUTUMN STORM TO BRING MUCH COLDER AIR AND POTENTIAL FOR
LIGHT SNOWFALL ACCUMULATIONS ON THURSDAY AND FRIDAY...

A SIGNIFICANT COLD FRONT WILL DIVE SOUTH INTO SOUTHEAST WYOMING
AND THE WESTERN NEBRASKA PANHANDLE ON THURSDAY. MUCH COLDER AIR
AND CONSIDERABLE CLOUD COVER WILL ACCOMPANY THIS FRONTAL PASSAGE
WITH DAYTIME HIGHS ONLY IN THE 40S ON THURSDAY. TEMPERATURES ARE
EXPECTED TO PLUNGE INTO THE 25 TO 30 DEGREE RANGE ACROSS MUCH OF
THE AREA BY FRIDAY MORNING...SETTING THE STAGE FOR A WIDESPREAD
FROST AND FREEZE EVENT. IN ADDITION TO THE COLD...RAIN IS LIKELY
TO DEVELOP FROM NORTH TO SOUTH DURING THE DAY ON THURSDAY BEFORE
QUICKLY CHANGING TO SNOW BY EARLY FRIDAY MORNING. AT THIS TIME IT
APPEARS THE HEAVIEST PRECIPITATION WILL FALL AS RAIN OR A WINTRY
MIX...SO ONLY MINOR SNOWFALL ACCUMULATIONS ARE EXPECTED. HOWEVER
AN INCH OR TWO OF WET SNOW CANNOT BE RULED OUT ON GRASSY SURFACES
AT ELEVATIONS ABOVE 4500 FEET THROUGH FRIDAY MORNING. FARMERS AND
RANCHERS...AS WELL AS THOSE WITH TRAVEL PLANS OR OUTDOOR INTERESTS
SHOULD BE PREPARED FOR ABRUPT CHANGES IN WEATHER CONDITIONS. STAY
TUNED TO THE LATEST NATIONAL WEATHER SERVICE FORECAST FOR FURTHER
INFORMATION REGARDING THIS STORM.
