TONIGHT...WHEN TEMPERATURES FALL THROUGH THE TEENS INTO THE SINGLE DIGITS...INDICES WILL DROP TO BETWEEN FIVE BELOW TO AROUND 5 ABOVE IN THE VALLEY WITH INDICES AS LOW AS 15 BELOW IN THE MOUNTAINS. THE COMBINATION OF COLD AIR AND WINDS WILL COMBINE TO GENERATE VERY LOW WIND CHILLS. THESE CONDITIONS CAN RESULT IN FROST BITE AND LEAD TO HYPOTHERMIA IF PRECAUTIONS ARE NOT TAKEN. THOSE VENTURING OUTDOORS SHOULD DRESS WARMLY...AND LIMIT THEIR TIME OUTDOORS. ALSO...ENSURE WATER PIPES ARE PROPERLY PROTECTED FROM THE COLD...AND MAKE SURE OUTDOOR ANIMALS HAVE ADEQUATE SHELTER.
