451 PM CST SUN JAN 29 2012

IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
HIGH PRESSURE WILL SLIDE EAST TONIGHT WITH ONSHORE FLOW RETURNING BY
MONDAY. THIS FEATURE WILL BEGIN BRINGING MOISTURE BACK TO THE AREA.
AFTERNOON MINIMUM RELATIVE HUMIDITY VALUES WILL RISE EACH DAY THIS
WEEK WITH THE POTENTIAL FOR RAIN TUESDAY NIGHT THRU FRIDAY MORNING
WHEN ANOTHER FRONT MAY MOVE THROUGH THE REGION.

RESPONSES TO QUESTIONS...
1...FLOW WILL BE SWITCHING TO ONSHORE DURING THE LATE MORNING HOURS.
WHILE IT IS POSSIBLE THAT THE WIND SHIFT HOLDS OFF UNTIL 1200...BEST
FORECAST INDICATES IT WILL OCCUR BEFORE 1200.

2...THERE WILL BE A PERIOD MONDAY NIGHT WHERE WINDS COULD DROP BELOW
5 KNOTS. AT THAT POINT WE COULD GET DECOUPLING OF THE WIND FIELD AND
CALM CONDITIONS COULD OCCUR. MOST LIKELY TIME FOR THIS TO OCCUR WOULD
BE BETWEEN MIDNIGHT AND 6 AM.

3...WE ARE NOT CARRYING FOG IN THE FORECAST FOR MONDAY NIGHT IN ANY
PRODUCTS. HOWEVER...RELATIVE HUMIDITIES ARE EXPECTED TO BE NEAR 100
PERCENT FOR A LARGE PORTION OF THE NIGHT MONDAY NIGHT...AND AT LEAST
SOME POTENTIAL FOR WINDS BECOMING CALM. AN INVERSION IS EXPECTED...SO
IF WINDS BECOME CALM...SMOKE COULD GET TRAPPED BELOW THE INVERSION AND
PRODUCE SIGNIFICANT VISIBILITY RESTRICTIONS. FOG IS LIKELY...AND IS
CARRIED IN PRODUCTS ON TUESDAY NIGHT.

4...CURRENT INDICATIONS ARE THAT THE LOWEST RH ON MONDAY WILL BE
CLOSER TO 40 PERCENT. AS THE WIND SHIFTS TO THE SOUTH AND SOUTHEAST
RH VALUES WILL INCREASE. THE ONLY WAY THE RH WOULD FALL BELOW 30
PERCENT ON MONDAY WOULD BE IF THE ONSHORE WIND DOES NOT DEVELOP.
