TODAY AND TONIGHT: AREAS OF DENSE FOG HAVE DEVELOPED OVER THE CWA
EARLY THIS MORNING. THE LOWEST VISIBILITIES ARE EXPECTED TO
CONTINUE THROUGH 9AM OVER THE NORTHWEST TWO THIRDS OF THE CWA
WHERE A DENSE FOG ADVISORY IS IN EFFECT FOR VISIBILITIES LESS THAN
A QUARTER MILE. EARLY MORNING SATELLITE IMAGERY/RAP ANALYSIS
SHOWED THE CIRCULATION AROUND A CLOSED LOW SPINNING OVER SOUTHWEST
MISSOURI. THIS CLOSED LOW WILL TRACK EAST THROUGH TONIGHT AND HELP
SUPPORT WEAK COLD FRONT TO DROP INTO OUR CWA. THE 00Z THU JAN
SOUNDING HAD A PWAT LESS THAN ONE INCH. WL STILL HAVE A SURFACE
RIDGE NOSING ACROSS OUR REGION FROM THE EAST THAT WILL WORK TO
HELP INCREASE LOW LEVEL MOISTURE. ONCE THE FOG BURNS OFF, DECENT
INSOLATION WILL WARM TEMPERATURES BACK ABOVE NORMAL THIS
AFTERNOON. ALTHOUGH THE CHANCE FOR RAIN WILL BE RATHER LOW TODAY,
ANTICIPATED PARAMETERS LATER THIS AFTERNOON AND EARLY EVENING
SUGGEST THERE COULD BE A FEW ISOLATED STRONG TO SEVERE STORMS
CAPABLE OF DAMAGING WIND GUSTS AND HAIL OVER OUR EASTERN ZONES.
THIS POTENTIAL WILL WAIN DURING THE EVENING AND THE CHANCE FOR ANY
RAIN END BY MIDNIGHT.
FRIDAY THROUGH WEDNESDAY: A RATHER DISTURBED WEATHER PATTERN IS
STILL EXPECTED FOR THE LONG TERM. WL STILL HAVE A STALLED FRONTAL
BOUNDARY ACROSS OUR SOUTHERN ZONES FRIDAY. UPPER LEVEL TROUGHING
WILL SAG SOUTH OVER OUR REGION AND DEVELOP A CLOSED LOW OVER OUR
CWA BY FRIDAY EVENING THAT WILL LINGER OVER OUR CWA SATURDAY
BEFORE SHIFTING TO THE SOUTHWEST SATURDAY NIGHT INTO SUNDAY.
SUNDAY MORNING THE CLOSED LOW IS PROGGED TO BE CENTERED OVER EAST
TEXAS WITH AN ASSOCIATED SURFACE LOW OVER SOUTHERN LOUISIANA. THIS
SYSTEM IS THEN PROGGED TO BEGIN MOVING NORTHEAST MONDAY ACROSS OUR
CWA THROUGH TUESDAY BEFORE LIFTING NORTHEAST OF OUR CWA TUESDAY
NIGHT. THIS WILL RESULT IN A PROLONGED PERIOD OF RAIN CHANCES
ALTHOUGH THE RAIN AMOUNTS WILL REMAIN LIGHT ENOUGH TO MITIGATE ANY
FLASH FLOODING CONCERNS OR ADDITIONAL RIVER FLOODING. THE
ASSOCIATED CLOUD COVER AND LOWER HEIGHTS WILL CONTRIBUTE TO COOLER
THAN NORMAL TEMPERATURES FOR THE WEEKEND AND THE START OF THE WORK
WEEK. DRY WEATHER IS EXPECTED BY TUESDAY EVENING AND WILL CONTINUE
WEDNESDAY. /22/
