EARLY MORNING WATER VAPOR IMAGERY/RAP ANALYSIS HAD A LARGE UPPER LEVEL TROUGH THAT EXTENDED NORTHEAST FROM NORTHERN MEXICO THROUGH THE MID MISSISSIPPI VALLEY AND OVER THE GREAT LAKES. THIS TROUGH WILL SHIFT EAST THROUGH THURSDAY WITH THE TROUGH AXIS MOVING ACROSS OUR CWA TONIGHT. A RIDGE OF HIGH PRESSURE CENTERED OVER THE SOUTHERN PLAINS WILL SHIFT SLOWLY EAST AND HELP BRING IN COOLER AND DRIER AIR. THIS AND THE PASSAGE OF THE UPPER LEVEL TROUGH WILL LEAD TO CLEARING SKIES FROM THE WEST THIS EVENING. COOLER THAN NORMAL TEMPERATURES ARE EXPECTED TODAY AND TONIGHT BUT TEMPERATURES WILL MODERATE THURSDAY UNDER SUNNY SKIES AND TOP OUT NEAR NORMAL.
728 AM EST WED JAN 27 2016 A COLD FRONT WILL MOVE THROUGH THE AREA EARLY THIS MORNING. THE FRONT WILL STALL OFF THE COAST AND A SERIES OF LOW PRESSURE CENTERS WILL MOVE NORTHEASTWARD ALONG THE FRONT. DRY HIGH PRESSURE WILL DOMINATE OVER THE WEEKEND. SURFACE ANALYSIS INDICATES ANA-TYPE COLD FRONT MOVING ACROSS THE FORECAST AREA EARLY THIS MORNING. STAYED ON THE COOLER SIDE OF GUIDANCE. AS WEAK LOW PRESSURE DEVELOPS OFF THE GEORGIA AND SOUTH CAROLINA COAST TONIGHT. USED THE GUIDANCE CONSENSUS FOR THE LOW TEMPERATURE FORECAST. LEANED TOWARD THE LOWER HIGH TEMPERATURE GUIDANCE BECAUSE OF CLOUDINESS WITH AN IN- SITU WEDGE.
HIGH PRESSURE ALOFT WILL PREVAIL OVER THE GREAT BASIN THROUGH THURSDAY.
IT WOULD BE FREEZING RAIN/SLEET BEFORE MOVING EAST AND TURNING OVER TO SNOW.

A COLD FRONT WILL PROGRESS THROUGH CENTRAL NORTH CAROLINA EARLY TODAY. A SERIES OF WEAK LOW PRESSURE WAVES WILL MOVE ALONG THE FRONT LATE TONIGHT THROUGH THURSDAY.
Consequently, forecast soundings are showing mixing in the low levels from west to east which should erode the low clouds by early afternoon. There will be some increase in mid-high clouds later today over northeast Missouri and west central Illinois with the approach of the next mid-level trough which is currently entering the north central CONUS. Temperatures will be warmer today, particularly where there will be the most sun.
UPPER AIR ANALYSIS LAST EVENING SHOWED A TROUGH EXTENDING FROM THE GREAT LAKES TO THE BAJA PENINSULA. THE COLD FRONT WAS OFF THE COAST AND HIGH PRESSURE WAS CENTERED OVER WEST TEXAS. THE UPPER LEVEL TROUGH AXIS WILL MOVE ACROSS TEXAS TODAY AND TONIGHT AND THE UPPER FLOW WILL BECOME NORTHWESTERLY. TEMPERATURES WILL BE BELOW NORMAL TODAY AND TONIGHT WITH FREEZING TEMPERATURES OVER MOST OF THE CWA THURSDAY MORNING.
BREEZY CONDITIONS WILL DEVELOP AS THE LOW APPROACHES AND RESULT IN SOME BLOWING SNOW ESPECIALLY ALONG AND WEST OF US-131 TONIGHT.
A COLD FRONT THAT BROUGHT THE RAIN YESTERDAY WAS ALSO WELL TO OUR EAST AND SHOULD CONTINUE MOVING FURTHER AWAY. AS HIGH PRESSURE BUILDS IN FROM THE WEST. WITH UPPER RIDGING NOSING NORTHWARD FROM THE BAJA TO THE US/CANADIAN CONTINENTAL DIVIDE. AND TROUGHING EXTENDING TO THE SOUTHERN PLAINS FROM A DEEP LOW SITUATED OVER NE CANADA. HIGH PRESSURE BUILDING IN FROM THE WEST SHOULD HELP KEEP ANOTHER SURGE OF MOISTURE MOVING TO THIS REGION FROM THE SOUTHERN PLAINS/ NW GULF OF MEXICO FOR THE NEXT FEW DAYS. STRONG COLD AIR ADVECTION WILL KEEP HIGH TEMPERATURES ONLY IN THE LOW/MID 40S FOR TODAY.
Thus, we are looking at highs ranging from the middle 40s across the eastern Ozarks to the lower 50s across western Missouri and southeastern Kansas. We are generally looking at lows in the lower 30s.

HOWEVER BOTH THE HRRR AND RAP WANT TO BREAK THESE INVERSIONS BY AFTN DUE TO DOWNSLOPE WINDS COMING OFF THE CHEYENNE RIDGE WHICH CAUSES HIGHS TO BE IN THE 45 TO 50 DEGREE RANGE. FOR NOW WILL KEEP HIGHS COOLER BUT DAY SHIFT MAY HAVE TO KEEP AN EYE ON THESE TRENDS. A RIDGE OF HIGH PRESSURE WILL BRING DRY AND MILD CONDITIONS TO THE CWA ON THURSDAY.
