1251 AM EST MON FEB 9 2015 WIDESPREAD STEADY SNOW WILL CONTINUE ACROSS THE REGION INTO EARLY MONDAY NIGHT AS LOW PRESSURE SLOWLY MOVES OFF THE MID ATLANTIC COAST ON MONDAY. THE SNOW WILL TAPER OFF MONDAY NIGHT AS HIGH PRESSURE BUILDS IN.
CURRENTLY THE COLD FRONT IS KNOCKING ON THE DOOR OF MIDDLE TN AS IT LOOKS TO BE RIGHT THROUGH CENTRAL KY AND NEAR THE TN BORDER. WITH THE COLD FRONT MOVING THROUGH THIS MORNING INTO THE AFTERNOON. CHANCES FOR PRECIP WILL MAINLY BE EAST OF I65 WITH A BETTER SHOT ON THE PLATEAU AS THE FRONT AND UPPER TROUGH SLIDE TO THE SOUTH AND EAST.
1256 AM EST MON FEB 9 2015 ADDITIONAL SNOWFALL IS EXPECTED OVERNIGHT INTO MONDAY AS AN UPPER LEVEL TROUGH OF LOW PRESSURE MOVES INTO THE REGION. SOME LIGHT FREEZING DRIZZLE IS EXPECTED THROUGH TONIGHT.
1229 AM EST MON FEB 9 2015 LOW PRESSURE WILL MOVE ACROSS OHIO TONIGHT WITH A COLD FRONT CROSSING THE REGION IN ITS WAKE.
A COLD FRONT WILL MOVE ACROSS THE AREA. SHORT RANGE MODELS SHOWING MAJORITY OF LIGHT SHWR ACTIVITY SHOULD FORM E OF I-65 COORIDOR AND MAINLY DURING THE LATE EVENING/OVERNIGHT HRS WHEN BEST MOISTURE POOLS AHEAD OF APPROACHING COLD FRONT AND UPPER LEVEL TROUGHING AND ASSOCIATED DYNAMICS MOVE ACROSS THIS PORTION OF MID STATE. WINDS ARE EXPECTED TO REMAIN GUSTY AS WE HEAD INTO THE OVERNIGHT HOURS AND A COLD FRONT APPROACHES FROM THE NORTHWEST. WE'LL REALLY BEGIN TO FEEL THE COOLER AIR MASS MONDAY NIGHT AS TEMPERATURES DROP TO AROUND 30 DEGREES.
/ISSUED 826 PM CST SUN FEB 8 2015/ A COLD FRONT IS APPROACHING THE MO/AR AND KY/TN BORDERS AT THIS TIME. A COLD FRONT EXTENDS FROM NORTHWEST OHIO THROUGH SOUTHERN ILLINOIS AND INTO NORTHWEST TEXAS. BEHIND THE COLD DRIER AND COOLER AIR WILL START TO MOVE INTO THE REGION OVERNIGHT BUT TEMPERATURES WILL REMAIN MILD FOR THIS TIME OF THE YEAR WITH LOWS MONDAY MORNING MAINLY IN THE 40S. HIGH PRESSURE WILL START TO BUILD INTO THE UPPER MIDWEST ON MONDAY KEEPING THINGS DRY AND SEASONABLE OVER THE REGION WITH HIGHS EXPECTED TO BE IN THE UPPER 40S TO MID 50S.
251 AM CST Mon Feb 9 2015 With the cold front well to the east, high pressure ridge to the west, and northwest flow over the region; am expecting cloudy skies to continue today, with northerly winds of around 15 mph.
These clouds should eventually scatter out later today as low-level ridging builds in, but depth of the moisture and weak cold air advection may make it difficult for much clearing to take place until mid/late afternoon.
A RIDGE EXTENDED FROM NORTHWESTERN MEXICO TO THE SOUTHERN CANADIAN PRAIRIES. AND A BROAD TROUGH REACHED FROM THE LOWER GREAT LAKES TO THE NORTHERN GULF OF MEXICO WATERS. SURFACE - HIGH PRESSURE CENTERS OVER THE NORTHWEST CANADIAN PRAIRIES AND NORTHERN QUEBEC SPRAWLED SOUTHWARD. HIGH PLAINS THROUGH THE MID-MISSISSIPPI VALLEY TO LOW PRESSURE IN THE OHIO VALLEY THEN CONTINUED EAST TO ATLANTIC WATERS SOUTH OF NEW ENGLAND. HIGH PRESSURE IN THE OPEN ATLANTIC ALONG LATITUDE 30 NORTH RIDGED ACROSS FL TO THE EAST GULF.
1208 AM EST MON FEB 9 2015 SEVERAL WAVES OF LOW PRESSURE WILL PASS TO OUR SOUTH ALONG A STALLED FRONT THROUGH MONDAY NIGHT. ARCTIC HIGH PRESSURE BUILDS IN BEHIND THIS SYSTEM FOR THE MIDDLE OF THE WEEK.
256 AM CST Mon Feb 9 2015 Backdoor cold front has pushed southwest through the forecast area overnight as another weak wave tracked into the mid MS valley. The lowest visibilities are currently located on the western edge of the fog/stratus over south central NE. Winds should decrease as the ridge approaches the forecast area limiting the amount of mixing as most sites are only a few degrees away from saturation. Regardless have lowered the high temperatures today due to the uncertainty of the cloud cover, which should roughly range from 40 in far northeast KS to 50 in central KS.
331 AM CST Mon Feb 9 2015 (Today and tonight) Full sun and light winds are in store today with surface ridging in place. The center of ridging will be sliding slowly east late afternoon and overnight, with a return of southeast to south winds of 5 to 10 mph.
1102 PM CST SUN FEB 8 2015 CONTINUED DRY AND VFR WITH UPPER LEVEL HIGH PRESSURE RIDGE MOVING OVERHEAD. BUT WINDS ARE ON THE DOWNWARD TREND WITH HIGH PRESSURE MOVING INTO THE AREA WHICH IS HELPING TO RELAX THE SURFACE PRESSURE GRADIENT. WINDS SHOULD REMAIN FAIRLY LIGHT TONIGHT WHILE UNDER THE INFLUENCE OF SURFACE RIDGING. THOUGH TEMPS WILL BE COOLER THAN THE PAST FEW DAYS THEY SHOULD REMAIN ABOVE FREEZING ACROSS THE FA AS CAA WITH THIS FRONT HAS BEEN WEAK AT BEST. WINDS WILL TURN TO THE SOUTHWEST AND INCREASE BY MID MORNING AS A LEE TROF DEVELOPS TO OUR NORTHWEST.
1150 PM CST SUN FEB 8 2015 AT H5 RIDGE OVER THE WESTERN CONUS WITH WEAK TROUGHING FROM THE GREAT LAKES INTO THE SOUTHEAST CONUS. THE TEMPERATURE FORECAST OVERNIGHT IS A PRODUCT OF THE WARMER MAV NUMERICAL GUIDANCE AS THE MET HAS SHOWN A RECENT COLD BIAS. WITH WEAK HIGH PRESSURE IN CONTROL. OVERNIGHT LOWS WILL BE COOLER THAN PREVIOUS NIGHTS. AT NORTH PLATTE THE FORECAST CALLS FOR A LOW IN THE LOWER 20S. BUT NOT AS FAR AS THE HIGHWAY 281 CORRIDOR.
104 AM EST MON FEB 9 2015 HIGH PRESSURE WILL REMAIN TO OUR NORTH THROUGH MONDAY AS WEAK LOW PRESSURE TRACKS ALONG A FRONTAL BOUNDARY OFF THE COAST.
315 AM CST MON FEB 9 2015 QUIET AND PLEASANT WEATHER WILL PERSIST FOR THE NEXT 2-3 DAYS AS UPPER LEVEL RIDGING REMAINS OVERHEAD.
A PREFRONTAL TROF WAS PRODUCING SOME LIGHT SHRA ACROSS THE CWA ATTM.
357 AM CST MON FEB 9 2015 TODAY-TONIGHT: BACKDOOR COLD FRONT WILL CONTINUE TO PUSH ACROSS THE AREA. -HOWERTON GFS/ECMWF IN FAIRLY GOOD AGREEMENT WITH RIDGE BUILDING IN THE WESTERN US AND TROUGHING IN THE EAST. SENDING MUCH COOLER AIR INTO THE AREA ON SAT. HOWEVER THERE WAS SUFFICIENT AGREEMENT BETWEEN MODELS AND SURROUNDING OFFICES TO HEDGE COOLER THAN GUIDANCE AT THIS POINT. IN WAKE OF A SHALLOW COLD FRONT "BACK-DOORING" SOUTH/SOUTHWEST ACROSS THE REGION.
422 AM EST MON FEB 9 2015 A LOW PRESSURE SYSTEM WILL MOVE EAST ALONG A FRONT DRAPED OVER THE AREA BRINGING A MIX OF PRECIPITATION TO THE AREA TONIGHT. H5 TROF DROPPING INTO CNTRL GREAT LKS AS OF THIS TIME.

EXTENDED THE FREEZING RAIN ADVISORY TO COVER THE NORTHERN THIRD OF THE AREA THROUGH 8AM. MUCH DRIER AIR ALOFT WILL OVERSPREAD THE AREA FROM THE NORTHWEST AHEAD OF THE NEXT TROUGH. IT WON'T BE UNTIL THIS AFTERNOON WITH THE PASSAGE OF THE SECONDARY TROUGH UNTIL THE CAA REALLY GETS UNDERWAY. ONCE THE LOW EXITS. WITH THE LOSS OF UPPER LEVEL MOISTURE AND THE SUPPLY OF ICE INTO THE LOWER CLOUD LEVELS. ANY PRECIP THAT MAY OCCUR LATER TODAY WOULD BE DRIZZLE OR FREEZING DRIZZLE. TROUGH AXIS WILL PASS THROUGH TONIGHT. EXITING THE RIDGES AFTER MIDNIGHT. THIS WOULD BE A GOOD TIME TO SEE PATCHY FREEZING DRIZZLE. FREEZING DRIZZLE THAT DOES DEVELOP WOULD HOLD ON LONGEST IN THE RIDGES.
TIMING OF THE LOWER VISIBILITIES SHOULD BE LESS THAN ADVISORY CRITERIA. THE TROUGH AXIS WILL CONTINUE TO MOVE SOUTHEAST TOWARD THE COAST OVERNIGHT. BUT WINDS WILL SHIFT TO NORTH AND INCREASE WITH THE PASSAGE OF THE TROUGH AXIS BY 11Z-12Z.
316 AM CST MON FEB 9 2015 BULK CLOUDINESS WITHIN A DEVELOPING/PASSING UPPER TROF WILL RULE THE BROAD PART OF THE DAY TODAY, AS COOLER AIR CONTINUES TO USHER INTO/ACROSS THE HEARTLAND.

UPPER RIDGE AXIS WILL CROSS THE REGION MONDAY WITH ABOVE AVERAGE TEMPS CONTINUING ALONG WITH MOSTLY SUNNY SKIES. AND IF THIS OCCURS MAX TEMPS WILL LIKELY END UP BEING COOLER THAN FORECAST OVER THE NRN PORTIONS OF THE CWA. NEXT UPPER TROUGH WILL QUICKLY APPROACH THE AREA MONDAY NIGHT. LINGERING SHALLOW LAYER OF COLDER TEMPS OVER NW SD MAY RESULT IN THE DEVELOPMENT OF FREEZING DRIZZLE/RAIN LATE MONDAY NIGHT INTO EARLY TUE MORNING. SREF SUGGESTS BULK OF FREEZING RAIN THREAT WILL EXIT N/E OF THE CWA BORDER THOUGH IT MAY CREEP INTO PERKINS/ZIEBACH COUNTIES.
409 AM EST MON FEB 9 2015 WEAK LOW PRESSURE WILL BRING LIGHT PRECIPITATION TO THE AREA THROUGH THE MORNING HOURS. EXTENDED THE FREEZING RAIN ADVISORY TO COVER THE NORTHERN THIRD OF THE AREA THROUGH 8AM. MUCH DRIER AIR ALOFT WILL OVERSPREAD THE AREA FROM THE NORTHWEST AHEAD OF THE NEXT TROUGH. IT WON'T BE UNTIL THIS AFTERNOON WITH THE PASSAGE OF THE SECONDARY TROUGH UNTIL THE CAA REALLY GETS UNDERWAY. ONCE THE LOW EXITS. WITH THE LOSS OF UPPER LEVEL MOISTURE AND THE SUPPLY OF ICE INTO THE LOWER CLOUD LEVELS. ANY PRECIP THAT MAY OCCUR LATER TODAY WOULD BE DRIZZLE OR FREEZING DRIZZLE. TROUGH AXIS WILL PASS THROUGH TONIGHT. EXITING THE RIDGES AFTER MIDNIGHT. THIS WOULD BE A GOOD TIME TO SEE PATCHY FREEZING DRIZZLE. FREEZING DRIZZLE THAT DOES DEVELOP WOULD HOLD ON LONGEST IN THE RIDGES.
AS A COLD FRONT NEARS FROM THE NW. A PRE- FRONTAL TROUGH EAST OF THE MAIN FRONT ALONG WITH WEAK LIFT/UPGLIDE WAS HELPING LIGHT SHOWERS TO FORM ACROSS THE AREA DURING THE OVERNIGHT. THINK SOME OF THE HIGHER ELEVATED TERRAIN OVER NE AL COULD RECEIVE SOME PATCHY DRIZZLE. SOME OF IT POSSIBLY FREEZING LATE. MODIFIED CANADIAN HIGH PRESSURE BUILDING IN FROM THE NW WILL BRING COOLER TEMPS TO THE AREA TODAY. THEN DRAMATICALLY COOLER WEATHER IS EXPECTED FOR THE LATTER WEEK AND BEYOND.

By Wed a deepening mid level trof will move to near the 4 corners region, this as a fast moving cold front in assocn with nrn branch of polar jet moves thru the plains. Models develop light QPF by early Thur AM, but based on location of upper low (too far to the w) the trend of lowering PoPs looks appropriate.
356 AM CST MON FEB 9 2015 ABOVE NORMAL WARMTH WILL BE ON TAP ONCE AGAIN TO BEGIN THE WEEK AS UPPER RIDGING HOLDS STRONG ACROSS THE SOUTHERN PLAINS DESPITE THE PRESENCE OF PACIFIC COAST ENERGY WEAKENING ITS WESTERN EXTENT INTO THE CENTRAL ROCKIES. RESULTANT LEE TROUGHING IN THE FRONT RANGE LEADING TO DOWNSLOPE BREEZES UNDERNEATH FULL INSOLATION WILL SPELL TEMPERATURES ONCE AGAIN IN THE MID-UPPER 70S. WILL SEE SOUTHWEST WINDS INCREASE TO 15- 20 MPH FOR A FEW HOURS THIS AFTERNOON ACROSS THE FAR SOUTHWEST PANHANDLE INTO THE SOUTH PLAINS WITH A TIGHTENING PRESSURE GRADIENT OWING TO THE AFOREMENTIONED DEVELOPMENT OF LEE TROUGHING.
