DISCUSSION
COOLER TEMPERATURES HAVE FILTERED IN BEHIND YESTERDAY'S COLD FRONT
PASSAGE, BUT IT HAS ALSO BROUGHT DRIER AIR IN WITH RELATIVE
HUMIDITY VALUES AS LOW AS 30% EXPECTED THIS AFTERNOON. HOWEVER,
NORTH/NORTHEASTERLY WINDS WILL BE MUCH LIGHTER TODAY AS HIGH
PRESSURE SETTLES IN AND THUS WE'LL ONLY SEE A LOW TO MODERATE
FIRE DANGER THIS AFTERNOON AND EVENING.
RAIN CHANCES INCREASE (40-80%) TONIGHT AND ESPECIALLY INTO
TOMORROW WHEN MODERATE RAINFALL WILL BE POSSIBLE AT TIMES. WINDS
WILL PICK UP SLIGHTLY OUT OF THE EAST, BUT RELATIVE HUMIDITY
VALUES OF 60-70% AND RAIN CHANCES WILL LEAD TO A LOW FIRE DANGER
TOMORROW AFTERNOON AND EVENING.

THE GRASSLAND FIRE DANGER INDEX WILL REACH THE LOW CATEGORY
THIS AFTERNOON. FAVORABLE WEATHER CONDITIONS OR A HIGH MOISTURE
CONTENT OF GRASSES, AND OTHER DRY ORGANIC MATERIAL ON THE
GROUND, INDICATE THAT THE PROBABILITY OF A FAST MOVING FIRE IS
LOW. OUTDOOR BURNING UNDER THESE CONDITIONS CAN USUALLY BE
WITH REASONABLE SAFETY PRECAUTIONS, BUT SHOULD BE MONITORED.
