AN OUTBREAK OF BITTER COLD WILL FOLLOW A LIGHT SNOW FALL OVERNIGHT AND THURSDAY MORNING. SNOWFALL OF 1 TO PERHAPS 3 INCHES WILL OCCUR LATE TONIGHT INTO THURSDAY.

THEN DURING THURSDAY NIGHT... TEMPERATURES WILL PLUMMET BELOW ZERO AS NORTHWEST WINDS OF 20 TO 30 MPH DEVELOP. THIS WILL SEND WIND CHILL VALUES INTO THE VERY DANGEROUS RANGE OF MINUS 30 TO MINUS 40 DEGREES BELOW ZERO.

THIS IS A SERIOUS OUTBREAK OF BITTER COLD. THIS TYPE OF SEVERE COLD IS QUITE DANGEROUS TO THOSE WHO WILL BE OUTSIDE... EVEN IF FOR JUST A FEW MINUTES WAITING FOR THE BUS FOR EXAMPLE.
