SHORT TERM
ISSUED 1151 PM CDT THU OCT 22 2026
TONIGHT THROUGH SATURDAY:
AREAS OF FOG WILL LIKELY CONTINUE IN THE EAST INTO FRIDAY
MORNING AND WILL BE DENSE AT TIMES. THE CURRENT DENSE FOG
ADVISORY RUNS UNTIL 10 AM FRIDAY AND MAY NEED TO BE EXPANDED A
BIT TO THE NORTH AND SOUTH BASED ON LATEST WEBCAMS AND
OBSERVATIONS. LATEST MODELS SHOW THAT THE BULK OF THE FOG AND
LOW CLOUDS SHOULD DISSIPATE BY MID-MORNING TOMORROW, BUT
WOULDN'T BE SURPRISED TO SEE THESE CONDITIONS HANG AROUND IN A
FEW SPOTS THROUGH LATE MORNING GIVEN THE LIGHT WINDS. SOUTHERLY
WINDS ARE EXPECTED TO PICK UP A BIT BY THE AFTERNOON ON THE BACK
SIDE OF HIGH PRESSURE, WHICH SHOULD HELP TO GET RID OF ANY
LINGERING FOG.
TEMPERATURES WILL LIKELY BE SLOW TO WARM IN THE EAST TOMORROW
GIVEN THE LINGERING CLOUDS/FOG, BUT THERE SHOULD BE ENOUGH
SUNSHINE IN THE AFTERNOON FOR HIGHS BACK UP IN THE UPPER 60S TO
NEAR 70. HIGHS IN THE 71-74 RANGE AREA LIKELY IN THE WEST GIVEN
MORE SUNSHINE.
SOUTHERLY WINDS WILL PERSIST FRIDAY NIGHT INTO SATURDAY, AS THE
HIGH TO THE EAST ISN'T EXPECTED TO BUDGE. THOUGH A FAIR AMOUNT
OF HIGH CLOUDS ARE LIKELY SATURDAY, ENOUGH FILTERED SUNSHINE IS
EXPECTED FOR HIGHS AROUND 70 AGAIN GIVEN THE CONTINUED WARM
SOUTHERLY LOW LEVEL FLOW.
