A CHANGE OVER TO SNOW HAS OCCURRED ACROSS STEWART COUNTY WITHIN
THE LAST HOUR. NO SIGNIFICANT ACCUMULATION HAS BEEN REPORTED AT
THIS TIME. THIS TREND SHOULD CONTINUE ACROSS LOCATIONS ALONG AND
NORTH OF INTERSTATE 40 AND WEST OF INTERSTATE 65...THROUGH 8 PM.

FOR OTHER LOCATIONS ACROSS THE MID STATE...LOOK FOR A CONTINUANCE
OF WIDESPREAD...MAINLY LIGHT...RAINFALL THROUGH 800 PM...AS
TEMPERATURES ARE EXPECTED TO CONTINUE TO REMAIN ABOVE FREEZING.
HOURLY RAINFALL AMOUNTS WILL GENERALLY BE BETWEEN ONE TENTH TO
AROUND ONE QUARTER OF AN INCH. HOWEVER...WITHIN THIS LARGE AREA OF
RAINFALL ACROSS THE MID STATE...EMBEDDED HEAVIER SHOWERS WILL
CONTINUE TO BE A POSSIBILITY...PRODUCING HOURLY RAINFALL AMOUNTS
FROM AROUND ONE QUARTER...TO AS MUCH AS AROUND ONE HALF OF AN
INCH...THROUGH 800 PM ALSO.

noooooooo! I'm going to click my heels and wish for the snow in early Feb to come sooner than the 2nd or later than the 8th. That always works, right?
