.DISCUSSION...
CLEARING OVER NRN AR MAY WORK ACROSS SEMO/SWKY THIS EVENING...BUT
OTHERWISE ANTICIPATE GENERALLY MORE CLOUDS THAN NOT FROM LINGERING
CYCLONE. WINDS CURRENTLY STILL GUSTING THRU 20S KTS MOST
PLACES...AND STILL HITTING L30S KTS FAR NE PTNS FA...SO WILL LIKELY
KILL OFF WIND ADVISORY BY MID-LATE PM AS GRADIENT SHOULD ONLY LESSEN
W/TIME AT THIS POINT. LINGERING --SN/FLURRIES CHC WILL CONT PRETTY
MUCH OFF/ON INTO/THRU THE WEEKEND...AS PVA/ENERGY AND MOISTURE
MAXES ARE PINWHEELED AROUND THE UPPER LOW. THINK PERHAPS BEST
CHANCE AT LIGHT ACCUMS ON GRASSY SURFACES WILL BE SUNDAY...WHEN
BOTH ECMWF/GFS SHOW LIGHT QPF WHICH MAY SUPPORT A DUSTING.
AFTER SUNDAY THE DEPARTING BROAD CYCLONE YIELDS TO A MORE ZONAL
PATTERN FOR EARLY-MID WEEK NEXT. THIS SHOULD PROVIDE A DRY
FORECAST TIL TUE NIGHT...WHEN MOISTURE TRANSPORT IN ZONAL FLOW
PATTERN RETURNS CHC PCPN. AIRMASS IS STILL COLD ENOUGH AT THAT
TIME TO SUPPORT FREEZING OR FROZEN PCPN SO WE'LL MAINTAIN THE
GOING EITHER/OR WORDING AND CARRY SOME FORM/CHC POP FROM TUE
NIGHT-WED-WED NIGHT. THIS TOO COULD END UP BEING A LIGHT
ACCUMULATION EVENT SO WE THREW A COUPLE TENTHS OF AN INCH INTO THE
SNOW GRIDS.
COLD/COLDER THAN MOS TEMPS THIS WEEKEND INTO EARLY NEXT WEEKEND
WITH SOME MODERATION MID TO LATE NEXT WEEK.
&&
.AVIATION...
SW WINDS WILL EASE A BIT TONIGHT WITH GUSTS NEAR OR BELOW 20KTS BUT
REMAIN STRONG ON SATURDAY WITH GUSTS AROUND 25KTS AND OCCASIONALLY
HIGHER DURING THE AFTERNOON HOURS...ESPECIALLY FURTHER SOUTH WHERE
THERE WILL BE SOME SUN AND BETTER MIXING. OTHERWISE PARTIAL CLEARING
IS MAKING ITS WAY NORTHEASTWARD ACROSS THE MISSISSIPPI RIVER ATTM
AND WILL ALLOW FOR VFR CONDITIONS AT ALL SITES FOR A PORTION OF THE
OVERNIGHT. LOWER CIGS WILL TRY TO RETURN FROM NW TO SE ON SATURDAY
BUT EXPECT MAINLY JUST LOW VFR. SLIGHT CHC OF SNOW SHOWERS MAINLY
NORTH OF THE OHIO RIVER ON SAT.
