WEDNESDAY...ALTHOUGH IN THE FARTHEST NORTHEASTERN COUNTIES IT

.LONG TERM...(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 243 PM CST MON FEB 23 2015

A WEAK WAVE WILL MOVE OVER THE PAH FORECAST AREA WEDNESDAY NIGHT
INTO THURSDAY, WITH GFS, ECMWF AND CANADIAN ALL GENERATING SOME VERY
LIGHT QPF OVER OUR REGION.  WITH COLDER AIR ALREADY IN PLACE DUE TO
OUR TUESDAY NIGHT COLD FRONTAL PASSAGE, ANY PRECIPITATION WILL BE IN
THE FORM OF LIGHT SNOW.  WENT WITH SOME SLIGHT CHANCE POPS ACROSS
JUST OUR NORTHWEST/WEST COUNTIES WEDNESDAY NIGHT, AND ACROSS ALL BUT
OUR FAR SOUTHWEST COUNTIES ON THURSDAY.

COLD HIGH PRESSURE WILL CONTINUE TO BUILD INTO THE UPPER MISSISSIPPI
VALLEY AND GREAT LAKES REGION THURSDAY NIGHT INTO FRIDAY NIGHT.
TEMPERATURES WILL REMAIN WELL BELOW NORMAL, WITH OUR COLDEST DAY
BEING FRIDAY WITH HIGHS ONLY IN THE 20S.  THE HIGH WILL MOVE EAST
INTO THE WEEKEND, AND TEMPERATURES WILL BEGIN TO MODERATE ON
SATURDAY.  WINDS WILL BECOME SOUTHERLY SATURDAY INTO SATURDAY NIGHT,
AND WE MAY ACTUALLY SEE NEAR SEASONAL READINGS SATURDAY NIGHT AND
SUNDAY.

THE SHIFT TO SOUTHERLY WINDS WILL BE DUE TO A WARM FRONT LIFTING
NORTH ACROSS THE AREA.  ECMWF AND CANADIAN SPREAD QPF ACROSS OUR
AREA SATURDAY NIGHT, WHILE THE GFS IS SLOWER AND MOSTLY HOLDS OFF
UNTIL SUNDAY.  WENT WITH CHANCE POPS FOR LIGHT SNOW SATURDAY NIGHT,
WITH HIGHEST POPS IN OUR WEST/NORTHWEST COUNTIES.  LOW PRESSURE WILL
APPROACH THE MIDDLE MISSISSIPPI VALLEY SUNDAY, WITH A COLD FRONTAL
PASSAGE SUNDAY NIGHT. WENT WITH HIGH CHANCE POPS FOR RAIN AREA WIDE

MIXING WITH SNOW ACROSS OUR WEST/NORTHWEST AREAS.  COLDER AIR
FILTERING IN WILL KEEP A RAIN/SNOW MIX IN OUR NORTHWEST COUNTIES, AS
PRECIP CHANCES CONTINUE ACROSS OUR ENTIRE REGION ON MONDAY.
