ECMWF HAS CONTINUED TO COME IN LINE WITH THE STRONGER GFS (AND IS NOW ACTUALLY A FEW MB LOWER) IN TERMS OF SURFACE RESPONSE TO THE AMPLIFIED SHORT WAVE TROUGH TRAILING TODAY'S LEAD SYSTEM. THE PARENT H50 TROUGH WILL TRACK RAPIDLY EWD FROM SOUTH TX ACROSS THE NRN GOMEX SAT-SAT NIGHT. WHICH WILL BE MUCH COOLER (MAINLY 40S WITH MID 50S MARTIN COAST). A SECOND POS TILT SHORT WAVE TROUGH MOVES ACROSS THE SERN CONUS/FL BY MON NIGHT WITH LITTLE IMPACT AS BACKDOOR COOL FRONT LOOKS TO WASH OUT TO THE NORTH. THE ECM ON THE OTHER HAND SHOWS MUCH MORE AMPLITUDE TO THE RIDGE OVER FL AND AN UPSTREAM SHORT WAVE TROUGH.
LOW PRESSURE IS NOW PUSHING OVER LAKE MICHIGAN. MIDLEVEL DRY AIR HAS GIVEN US COPIOUS FREEZING DRIZZLE. AS THE LOW DRAWS FARTHER AWAY.
Meanwhile, upstream a sharpening mid level trof INVOF 4 Corners Region will move thru the CWFA between 06Z/17 and 12Z/17. Despite nw downslope winds Sat cold advection will offset and it be noticeably cooler, probably 10-15 degrees cooler. Dry air in wake of the front will make for a cold Sun AM, but in the afternoon temps will rebound just ahead of another cold front. The front will make for cooler temps Mon PM, but still near normal. Yet another shrtwv trof and assocd front may near/move into the nrn CWFA late Tue PM.
THE COLD FRONT CURRENTLY MOVING INTO CENTRAL CA/NV EARLY THIS MORNING WILL QUICKLY PUSH SOUTH INTO NORTHERN ARIZONA BY THIS AFTERNOON. PRECIPITATION WILL BE FOCUSED FROM ABOUT NOON THROUGH 6 PM MST WHEN THE COLD FRONT MOVES THROUGH THE REGION.
256 PM CST FRI JAN 15 2016 A SERIES OF COLD FRONTS WILL LEAD TO INCREASING COLDER AIR MOVING SOUTH ACROSS THE FORECAST AREA THROUGH THE WEEKEND. THE FIRST COLD FRONT WILL PUSH THROUGH THE AREA THIS EVENING. A RATHER SIGNIFICANT LOW PRESSURE AREA WILL PUSH SOUTH OUT OF CANADA INTO THE GREAT LAKES BY SAT NIGHT. THIS LOW WILL HELP DISLODGE SOME ARCTIC AIR SOUTH INTO THE PLAINS FOR LATE SAT INTO EARLY SUN AS THIS LOW PRESSURE AREA DROPS SOUTH ACROSS THE GREAT LAKES. THIS WILL LEAD TO A SLIGHT WARMUP BACK TOWARDS NORMAL FOR MON AS A WEAK RIDGE MOVES OVER THE AREA IN THE NW FLOW. NOT ENTIRELY SURE ON WHETHER THE PRECIP WILL BE IN THE FORM OF RAIN OR SNOW GIVEN TEMPS IN THE LOW TO MID 30S.
301 PM CST FRI JAN 15 2016 Cooler conditions are occurring across the area this afternoon, behind a cold front that passed through the region last night.

VFR CONDITIONS PREVAIL AT ALL TAF SITES AND THESE CONDITIONS WILL CONTINUE THROUGH THE PERIOD AS HIGH PRESSURE PREVAILS. A NICE DAY IS ON TAP FOR THE ARKLAMISS AS HIGH PRESSURE RIDGING PREVAILS ACROSS THE AREA FROM A HIGH CENTERED OVER THE OHIO VALLEY. A COLD FRONT WILL SWING SOUTH ACROSS THE AREA SATURDAY AFTERNOON AND THERE WILL BE JUST ENOUGH MOISTURE TO SQUEEZE OUT A FEW LIGHT RAINSHOWERS ACROSS THE AREA AS IT PASSES.
A cold front will move through the region overnight, bringing strong, gusty northwesterly winds and a chance of generally light rainfall. Increasing lift in advance of the associated mid level cold front will bring rain chances tonight. The precip should end before cold enough air works its way into the region in the low levels behind the strong cold front.
A COLD FRONT WILL MOVE THROUGH THE REGION OVERNIGHT, BRINGING STRONG, GUSTY NORTHWESTERLY WINDS AND A CHANCE OF GENERALLY LIGHT RAINFALL. INCREASING LIFT IN ADVANCE OF THE ASSOCIATED MID LEVEL COLD FRONT WILL BRING RAIN CHANCES TONIGHT.

THE TROUGH THAT PRODUCED STORMY WEATHER ACROSS MUCH OF THE CONUS OVER THE PAST FEW DAYS WAS FINALLY ON A WEAKENING STAGE. AN UPPER DISTURBANCE MOVING ESE OVER THE CANADIAN ROCKIES WILL HELP REAMPLIFY THIS TROUGH. DRY WEATHER WITH HIGH TEMPERATURES BELOW/NEAR SEASONABLE NORMS IS FORECAST TODAY AS HIGH PRESSURE CONTROLS THE GENERAL WEATHER SITUATION. AN APPROACH OF THE UPPER TROUGH FROM THE NW WILL BRING ANOTHER COLD FRONT ACROSS THE AREA DURING SATURDAY. COLDER AIR FILTERING IN FROM THE NW WILL BRING A GOOD CHANCE OF FREEZING WEATHER FOR THE ENTIRE AREA SAT NIGHT/SUN MORNING.
Upper-level impulse coming across the Pacific Northwest will become our main weather player, as it emerges from the northern Rockies later today and develops a surface cyclone over the Panhandle region. Trailing cold front will cross central Kentucky around midday, with best precip chances along and behind the front in a typical anafront configuration.
