DISCUSSION
KEY MESSAGE 1) A SIGNIFICANT/PROLONGED ARCTIC OUTBREAK WILL CONTINUE
THROUGH THIS WEEKEND, WITH PERIODS OF DANGEROUS EXTREME COLD.
OUTDOOR EXPOSURE SHOULD BE LIMITED.
CLOUDS THAT WILL DEVELOP DURING THE AFTERNOON WILL DIMINISH DURING
THE EVENING AS A SHEARED OUT SHORT WAVE PASSES ACROSS THE REGION.
AIR TEMPERATURES WILL FALL BELOW 0 AGAIN EXCEPT IN PARTS OF NORTHERN
KENTUCKY. WINDS WILL BE RELATIVELY LIGHT, BUT THE COMBINATION WILL
ALLOW FOR WIND CHILL REACHING OR EXCEEDING COLD WEATHER ADVISORY
CRITERIA. BASED ON THE LATEST GUIDANCE, HAVE EXPANDED THIS A BIT
FURTHER SOUTH TO NEAR THE OHIO RIVER.
THERE IS AN EVER SO SLIGHT MODERATION TO THE ARCTIC AIRMASS ACROSS
THE REGION STARTING TOMORROW. IN ADDITION, THERE WILL BE A
CONSIDERABLE AMOUNT OF HIGH AND MID CLOUDS, SO THE POTENTIAL FOR WIND
CHILL REACHING ADVISORY THRESHOLD ON THURSDAY NIGHT LOOKS RATHER LOW
AT THIS POINT.
HOWEVER, AN ELONGATED SHORT WAVE PIVOTING ACROSS THE REGION AT THE
END OF THE WEEK WILL USHER IN A REINFORCEMENT OF ARCTIC AIR. THIS
RESULTS IN PROBABILITIES OF REACHING EXTREME COLD WARNING LEVELS
FRIDAY NIGHT TO 50 PERCENT OR GREATER. THERE REMAINS SOME POTENTIAL
FOR RECORD COLD AIR TEMPERATURES, ALTHOUGH THAT HAS TRENDED TOWARDS
FEWER POSSIBILITIES.
WHILE FRIDAY NIGHT AND SATURDAY ARE FORECAST TO BE THE COLDEST PARTS
OF THE FORECAST, BITTER CONDITIONS WILL CONTINUE THROUGH THE REST OF
THE WEEKEND FOLLOWED BY WARMER, ALTHOUGH STILL BELOW NORMAL, READINGS
HEADING INTO NEXT WEEK.
KEY MESSAGE 2) SEVERAL CHANCES OF LIGHT PRECIPITATION.
A MINOR PERTUBATION WILL TRACK FROM CENTRAL ILLINOIS INTO KENTUCKY
LATE THURSDAY NIGHT INTO FRIDAY. THERE IS A WEAK BAND OF
FRONTOGENESIS ASSOCIATED WITH THIS THAT WILL GENERATE SOME LIGHT
PRECIPITATION. THERE IS SOME DISAGREEMENT IN THE MODEL SUITE
REGARDING THE TRACK THAT THIS WILL TAKE. MUCH OF THE GUIDANCE TAKES
THIS JUST SOUTH OF THE AREA, BUT THERE ARE SOME RUNS THAT BRING THE
PRECIPITATION, WHICH WOULD BE SNOW, ACROSS THE FAR SOUTHERN COUNTIES
WHICH WARRANTS LOW CHANCE POPS.
A WEAK SHORT WAVE WILL DROP ACROSS THE AREA SUNDAY NIGHT AND MONDAY
ALONG WITH SOMEWHAT ROBUST LOW LEVEL WARM AIR ADVECTION. AVAILABLE
MOISTURE MAY BE IN QUESTION WHICH IS RESULTING IN THE NBM ONLY
CARRYING 20 POP, ALTHOUGH CLUSTER ANALYSIS SHOWS THAT ABOUT HALF OF
THE ENSEMBLE MEMBERS SUGGEST A MUCH HIGHER CHANCE OF MEASURABLE
PRECIPITATION. SO WILL HAVE TO SEE HOW THIS EVOLVES WITH THE
POSSIBILITY OF SOME LIGHT SNOW.
BETTER CHANCE OF PRECIPITATION LOOKS TO BE NEXT WEDNESDAY. THE
PERSISTENT LONG WAVE TROUGH THAT HAS KEPT BRINGING ARCTIC AIR ACROSS
THE EASTERN PART OF THE CONTINENT WILL HAVE FINALLY BECOME
PROGRESSIVE AND MOVED OFF TO THE EAST. IN ITS WAKE, A POSITIVELY
TILTED SHORT WAVE WILL TRACK OUT OF THE NORTHERN ROCKIES AND PUSH
INTO THE MID MISSISSIPPI VALLEY BY THE END OF THE PERIOD. THIS SHOULD
BRING THE APPROACH OF A COLD FRONT, ALTHOUGH THERE IS THE TYPICAL
SPREAD IN SOLUTIONS THAT FAR OUT IN TIME. BUT AT THIS STAGE, IT
LOOKS LIKE IT WILL BRING THE NEXT BETTER CHANCE OF PRECIPITATION.
TEMPERATURES MAY WARM SUFFICIENTLY TO ALLOW FOR A MIX/CHANGEOVER TO
RAIN IN SOUTHERN COUNTIES.
AVIATION /18Z WEDNESDAY THROUGH MONDAY/
STRATOCUMULUS IS FORECAST TO DEVELOP EARLY WHICH MAY BRING A FEW
HOURS OF MVFR CEILINGS TO ALL BUT THE CINCINNATI TERMINALS. THE BASES
WILL LIFT ABOVE 3 KFT TOWARDS 00Z AND THEN CLOUDS WILL CLEAR OUT
BEFORE 06Z. MVFR CEILINGS MAY DEVELOP AGAIN VERY LATE IN THE PERIOD.
WEST WINDS TO AROUND 15 KT TO START WILL DECREASE BELOW 10 KT AROUND
00Z AND BECOME EVEN LIGHTER DURING THE LATTER PART OF THE PERIOD.
OUTLOOK...MVFR CEILINGS POSSIBLE THURSDAY AFTERNOON, FRIDAY
AFTERNOON, AND THEN AGAIN SATURDAY AFTERNOON INTO SUNDAY MORNING.
