THROUGH MONDAY: CONTINUED DRY WITH COOLER THAN NORMAL MORNING LOWS
AND SLIGHTLY WARMER THAN NORMAL AFTERNOON HIGHS MONDAY. SURFACE
RIDGING WILL CONTINUE ACROSS THE REGION FROM THE NORTHEAST RESULTING
IN AN EAST WIND AND KEEPING THE GULF CLOSED THROUGH MONDAY. RIDGING
ALOFT WILL REMAIN OVER THE REGION AS WELL. TOGETHER THESE FEATURES
WILL RESULT IN DECENT RADIATIONAL COOLING TONIGHT AND NEAR FULL
INSOLATION MONDAY. THE RESULT WILL BE CRITICALLY LOW AFTERNOON
MINIMUM RELATIVE HUMIDITY MAINTAINING FIRE DANGER CONCERNS. /22/
MONDAY NIGHT THROUGH SATURDAY...HIGH PRESSURE AT THE SURFACE
CENTERED TO OUR NORTH AND INCREASING RIDGING ALOFT FROM THE WEST
THROUGH THE WEEK, WILL MAINTAIN QUIET WEATHER ACROSS THE FORECAST
AREA. THE OVERALL DRY AIR MASS WILL REMAIN ACROSS THE REGION
THROUGH THE WEEK AS DEW POINTS GENERALLY MIX INTO THE 30S & 40S EACH
AFTERNOON. HOWEVER, TEMPERATURES WILL STEADILY WARM EACH DAY. THIS
WARMING WILL BE FELT MORE WITH DAYTIME HIGHS, THAN WITH OVERNIGHT
LOWS. LOWS THROUGH THE PERIOD WILL GENERALLY RANGE FROM THE MID 40S
TO MID 50S. MEANWHILE HIGHS ON TUESDAY WILL RANGE FROM THE UPPER
70S TO MIDDLE 80S. THEN BY SATURDAY, THEY'LL HAVE INCREASED INTO
THE LOWER 80S TO AROUND 90.
THESE INCREASING HIGH TEMPERATURES IN THIS DRY AIR MASS WILL RESULT
IN AFTERNOON MINIMUM RELATIVE HUMIDITY VALUES FALLING TO CRITICALLY
LOW VALUES, I.E. GENERALLY INTO THE 20-30% RANGE. THIS, COUPLED
WITH THE EXTREMELY DRY SOIL CONDITIONS ACROSS THE AREA WILL CONTINUE
TO PROMOTE AT LEAST A "LIMITED THREAT" FOR DANGEROUS FIRE CONDITIONS
ACROSS THE FORECAST AREA THROUGH THE PERIOD. PLEASE CONTINUE TO
MONITOR THE LATEST FORECAST AND OUTLOOK THROUGH THE WEEK, AS SOME
CATEGORICAL ADJUSTMENT COULD BE MADE TO PORTIONS OF, IF NOT ALL OF,
THE FORECAST AREA. /19/
