.PREV DISCUSSION... /ISSUED 414 AM CST SUN DEC 28 2014/

DISCUSSION...
NO SURPRISES TODAY AS UPPER TROUGH WILL SWEEP EAST OF THE AREA BY
AFTERNOON WHICH WILL ALLOW THE HIGH LEVEL CLOUDINESS CURRENTLY
OVER THE AREA TO CLEAR. TEMPERATURES WILL WARM TO THE UPPER 30S TO
LOWER 40S THIS AFTERNOON ALLOWING WHAT IS LEFT OF THE SNOW TO
MELT.

TEMPERATURES WILL AGAIN WARM WELL INTO THE 40S MONDAY WITH SOME
INCREASE IN CLOUDINESS. THE MUCH ADVERTISED ARCTIC COLD FRONT WILL
THEN SWEEP ACROSS THE AREA MONDAY NIGHT BRINGING THE COLDEST
WEATHER OF THE SEASON TO DATE FOR TUESDAY AND WEDNESDAY.

THE NEXT STORM SYSTEM WILL BE DIGGING SOUTH ALONG THE WEST COAST
DURING THE MIDDLE PART OF THE WEEK BEFORE IT TURNS EAST AND HEADS
OUR WAY FOR THE LATTER PART OF THE WEEK. THE EVENTUAL TRACK AND
TIMING OF THIS SYSTEM REMAINS HIGHLY UNCERTAIN AND THIS WILL
AFFECT PRECIPITATION TYPE...INTENSITY AND DURATION BY THE TIME WE
GET TO NEXT WEEKEND.

PRIOR TO THAT TIME...PERCIPITATION WILL BREAK OUT IN A STRONG LOW
LEVEL WARM AIR ADVECTION REGIME LATE THURSDAY INTO FRIDAY.
INITIALLY DRY LOW LEVELS MAY ALLOW FOR SOME SLEET AT THE
ONSET...WITH FREEZING RAIN AND RAIN THEN BECOMING THE DOMINANT
PRECIPITATION TYPES THURSDAY NIGHT. TEMPERATURES SHOULD WARM ABOVE
FREEZING EVERYWHERE FRIDAY ALLOWING FOR A CHANGEOVER TO RAIN.

AS THE CENTER OF THE UPPER LOW APPROACHES LATER FRIDAY NIGHT AND
SATURDAY...PRECIPITATION TYPE AND DURATION BECOMES MUCH MORE
QUESTIONABLE. THE MAJORITY OF THE MODELS SUGGEST A TRACK JUST TO
OUR NORTH WHICH WOULD RESULT IN ONLY MINIMAL WINTRY PRECIPITATION
AT BEST. THERE REMAINS A CHANCE FOR A TRACK FARTHER TO THE
SOUTH...SO ACCUMULATING SNOW CANNOT YET BE RULED OUT AS WE HEAD
INTO THE FIRST PART OF NEXT WEEKEND. STAY TUNED!

STAYED CLOSE TO GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS.
