PREVIOUSLY ADVERTISED COLD FRONT HAS CLEARED ALL OF DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY AND IS SURGING ACROSS THE LOWER TEXAS COASTAL WATERS. AN UPTICK IN WINDS IS POSSIBLE LATER THIS AFTERNOON AND THIS EVENING AS THE MIDLEVEL TROUGH THAT PUSHED THE COLD FRONT ACROSS THE AREA LIFTS NORTHEAST. LOWS TONIGHT WILL BE SIGNIFICANTLY COLDER THAN RECENT NIGHTS WITH TEMPERATURES PLUMMETING INTO THE UPPER 30S ACROSS THE RANCHLANDS AND BRUSH COUNTRY AND INTO THE LOWER 40S ACROSS THE VALLEY. WINDS WILL DIMINISH THROUGH THE DAY TOMORROW AS HIGH PRESSURE OVER THE BIG BEND AREA SHIFTS EAST ACROSS TEXAS.
449 PM EST SUN DEC 27 2015 LOW PRESSURE WILL EXIT ACROSS THE MARITIMES TONIGHT. ARCTIC HIGH PRESSURE WILL BUILD ACROSS THE REGION LATER TONIGHT INTO MONDAY.
THE DEEP UPPER LOW OVER TEXAS EJECTS TO THE ARLATEX REGION WITH A COLD FRONT FRONT AND BAND OF SHOWERS EXTENDING FROM THE ARKANSAS/OKLAHOMA AREA THROUGH THE CENTRAL GULF.
NORTHCENTRAL AND SOUTHWEST MONTANA BRIEFLY UNDER THE INFLUENCE OF HIGH PRESSURE ALOFT TODAY BEFORE GIVING WAY TO AN APPROACHING LOW PRESSURE TROUGH TONIGHT AND MONDAY. AS TROUGH MOVES IN MONDAY, IT OPENS THE DOOR FOR COOLER AIR TO SLIDE DOWN FROM THE CANADA DROPPING TEMPERATURES A FEW DEGREES BY MIDWEEK. AN UPPER LEVEL HIGH PRESSURE RIDGE IS BEING DISPLACED TO THE EAST TODAY BY AN UPPER LEVEL LOW PRESSURE TROUGH APPROACHING THE PACIFIC NRTHWEST COAST. CLOUD COVER WILL INCREASE AND LOWER THROUGH THE PERIOD AS THE TROUGH APPROACHES THE ROCKIES. A COLD FRONT ASSOCIATED WITH THE APPROACHING TROUGH WILL MOVE INTO THE AREA EARLY MONDAY MORNING. THE COLD FRONT WILL SPREAD SOUTH-SOUTHEAST WITH SNOW AND LOCAL MVFR/IFR CONDS DEVELOPING DURING THE MORNING AND EARLY AFTERNOON.
For tonight and Monday, the Winter storm system, with a strong upper low, will continue to track from southwest Texas and northeastward into eastern Oklahoma by morning, then lift into Missouri on Monday.
THE ANTICYCLONIC WINDS ASSOCIATED WITH THE HIGH THAT IS CAUSING THE VEERING WINDS WILL HELP REDUCE THE OVERALL WEAK LES AND HAVE IT BECOME MORE OF AN UPSLOPE SNOW. ANOTHER TROUGH MOVES INTO THE PLAINS 00Z WED AND INTO THE UPPER GREAT LAKES ON WED. GFS AND ECMWF SHOW A BROAD 500 MB TROUGH OVER THE NORTHERN AND CENTRAL PLAINS STRETCHING INTO THE UPPER GREAT LAKES 12Z THU. THE TROUGH AXIS MOVES TO THE EAST INTO THE LOWER GREAT LAKES 12Z FRI. 12Z SAT WITH A BROAD TROUGH OVER THE ERN U.
ITS ASSOCIATED COLD FRONT WILL PUSH INTO OUR AREA MONDAY NIGHT. THE LOW LEVEL JET WILL STRENGTHEN FROM THE SOUTHEAST. WHILE THERE IS STILL SOME QUESTION IF THE LOW LEVEL STABLE LAYER WILL BE FAVORABLE FOR MOUNTAIN WAVE DEVELOPMENT. WILL CONTINUE THE HIGH WIND WATCH AS IS.
AT THIS TIME IT DOES NOT APPEAR THAT IT CAN GET DEEP ENOUGH FOR STRATIFORM PRECIPITATION SUCH AS FREEZING DRIZZLE OR SNOW GRAINS. WHICH HAS SHIFTED THE UPPER LOW SLIGHTLY FURTHER EAST. UPPER LOW WILL BEGIN TO EJECT NORTHEAST OUT OF TEXAS EARLY MONDAY. WITH SIGNIFICANT WARM ADVECTION SPREADING AROUND THE UPPER LOW THROUGH THE DAY.
120 PM PST SUN DEC 27 2015 WEAK OFFSHORE FLOW WILL TURN BACK ONSHORE TONIGHT AND MONDAY AS A LOW PRESSURE TROUGH APPROACHES FROM THE NORTHWEST.
BELOW FREEZING TEMPERATURES CAN BE EXPECTED AGAIN TONIGHT ACROSS MOST OF THE MOJAVE DESERT REGION.
THE UPPER LOW IS EXPECTED TO MOVE EAST ACROSS SOUTHERN TEXAS TODAY AND THEN MOVE NORTHEAST INTO CENTRAL TEXAS TONIGHT. THE LOW IS FORECAST TO TAKE ITS NORTHEAST TRACK INTO EASTERN OKLAHOMA/SOUTHWEST MISSOURI MONDAY. BY MONDAY EVENING THE LOW SHOULD BE CENTERED OVER SOUTH CENTRAL IOWA.
354 PM CST SUN DEC 27 2015 HAVE ISSUED WINTER STORM WARNING AND FREEZING RAIN ADVISORY SOUTH. WITH THE HIGHER TOTALS ACROSS THE NORTHWEST THIRD OF THE FORECAST AREA.
BUT CHANGES ARE ON THE WAY TODAY AS A STRONG COLD FRONT IS BEGINNING TO MOVE TOWARDS SOUTHEAST TEXAS.
352 PM CST SUN DEC 27 2015 WATER VAPOR IMAGERY CONTINUES TO SHOW AN IMPRESSIVE UPPER LEVEL LOW SLOWLY MOVING EAST ACROSS WEST TEXAS. WITH THE VERY SLOW MOVING COLD FRONT NEARLY STALLED OVER NORTHEAST TEXAS. THIS COLD FRONT HAS MOVED APPROXIMATELY 40 MILES SINCE 8 AM THIS MORNING. THE SEVERE WEATHER POTENTIAL IS ALSO ON THE INCREASE WITH THE LEADING EDGE OF THE COLD FRONT AND WITH THE DISCRETE THUNDERSTORMS OUT IN FRONT OF THE COLD FRONT. AS FOR THE PROGRESSION OF THE COLD FRONT. THE SLOW MOVEMENT OF THIS COLD FRONT WITH MAKE FORECASTING THE HOURLY TEMPERATURE TRENDS A CHALLENGE AS WELL AS THE OVERNIGHT LOWS. WITH TEMPERATURES FALLING INTO THE LOWER 40S TO LOWER 50S. WITH TEMPERATURES FALLING QUICKLY ONCE THE COLD FRONT FINALLY PASSES. AS THE UPPER LEVEL LOW QUICKLY LIFTS OFF TO THE NORTHEAST.
If this were to occur we could begin to see a mix of Freezing rain and/or snow begin to fall across areas west of I-49 Monday afternoon. The storm system will be in the process of shifting north of the region Monday night with some light freezing drizzle or snow falling in the wrap around area.

THE AREA OF HIGH PRESSURE WILL DOMINATE THE WEATHER ACROSS REGION THIS EVENING BEFORE CLOUDS OUT AHEAD OF THE NEXT SYSTEM MOVES IN FROM THE SOUTH MONDAY MORNING. AS THE RIDGE MOVES EAST. WILL KEEP THE HIGHER POPS/LOW QPF GRIDS FROM PREVIOUS SHIFT.
POWERFUL UPPER CYCLONE WAS CENTERED JUST WEST OF THE BIG BEND REGION BEFORE NOON AND HAS EXHIBITED A STEADY EASTERLY MOTION AFTER A TEMPORARY STALL EARLIER THIS MORNING. OVERALL FORECAST FOR SEVERAL MORE INCHES OF SNOW /5-12 IN LUBBOCK/ LOOKS SOLID ESPECIALLY WITH SNOW RATIOS INCREASING IN THE N-NW SECTOR OF THE UPPER LOW.
A STRONG COLD FRONT HAS PUSHED ACROSS MUCH OF DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY THIS MORNING AND IS NOW PUSHING THROUGH BROWNSVILLE. SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATE THAT A STRONG COLD FRONT IS ALONG A HBV TO APY LINE WITHIN DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY. SURFACE OBSERVATIONS INDICATE THAT A STRONG COLD FRONT IS MOVING THROUGH THE WESTERN PORTION OF THE CRP CWFA RIGHT NOW. INDICATING A POSSIBLE WARMTH SPIKE TODAY IN ADVANCE OF THE FRONT AND MUCH COOLER CONDITIONS TONIGHT AND MONDAY. MILD H5 RIDGING.
TODAY THROUGH MONDAY NIGHT CURRENT SURFACE ANALYSIS SHOWS HIGH PRESSURE NOW CENTERED OVER THE REGION. AN INTENSE LOW PRESSURE SYSTEM HAS DEVELOPED OVER SOUTHERN NM AND SOUTHWEST TX. WITH POSITIVELY TILTED RIDGE FROM CA TO THE NORTHERN ROCKIES.
1152 AM CST SUN DEC 27 2015 SHOWERS AND THUNDERSTORMS CURRENTLY MOVING FROM WEST TO EAST ACROSS THE AREA ASSOCIATED WITH COLD FRONT AND UPPER LEVEL DISTURBANCE. FORECAST UPDATED TO ACCOUNT FOR FASTER INTRUSION OF COLD FRONT INTO FAR WRN PART OF THE FORECAST AREA THIS MORNING. WITH INCREASING UPPER SUPPORT AS UPPER LOW CONTINUES EWD ACROSS CENTRAL TX.
THE SOUTHERN PORTION IS EXPECTED TO INTENSIFY AND BECOME OCCLUDED AS THE UPPER TROUGH INTENSIFIES ACROSS THE DESERT SOUTHWEST AND SWINGS INTO TEXAS TODAY. AS THE LOW PULLS NORTHWARD.
WITH LIGHT NORTHWEST FLOW AND MAINLY SUNNY SKIES UNDER AN ARCTIC HIGH PRESSURE DOME. UPPER LEVEL RIDGE OVER THE ROCKIES WILL MOVE OVER THE NORTHERN PLAINS FOR SUN NIGHT. FAIRLY STRONG UPPER LEVEL LOW OVER WEST TX TO MOVE INTO THE IA/IL/WI AREA BY 06Z TUE AND OFF THE NEW ENGLAND COAST BY 12Z WED. A WEAKER UPPER LOW WILL REMAIN BEHIND AND MOVE OVER THE FORECAST AREA FOR TUE AND WED AND PRODUCE A FAIR AMOUNT OF SNOW FOR THE AREA. 5 INCHES ON THE EAST SIDE OF THE UPPER LOW. GUIDANCE IN GOOD AGREEMENT DEVELOPING A STRONG WESTERN CONUS RIDGE AND NORTHWEST FLOW ALOFT OVER THE REGION.
A strong ridge of high pressure will dominate the region by late week and into the weekend promoting strong valley inversions, fog and low clouds, and sunshine in the mountains.
232 PM CST SUN DEC 27 2015 Quad 2 pcpn pattern just north of warm front will continue into early overnight hours. as the Low tracks into NE MO/WCNTRl IL by 00z (Tue). This will trail a relatively weak cold front over the extreme southeast portion of the area near Hopkinsville.
BEFORE IT RETREATS NORTHWARD AS A WARM FRONT. THIS WILL BE THE HIGH IMPACT WEATHER DAY OUT OF THE NEXT 7 AS STRONG TO SEVERE THUNDERSTORMS WITH THE POSSIBILITY OF FLASH FLOODING CAN BE EXPECTED.
TONIGHT AND MONDAY THE LATEST RAP ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW ARCTIC HIGH PRESSURE CENTERED OVER THE NORTHERN GREAT PLAINS AND SOUTH-CENTRAL CANADA EARLY THIS AFTERNOON. NORTHWEST WINDS AROUND THE HIGH CONTINUE TO BRING CLOUDS OFF LAKE SUPERIOR. UPPER LEVEL LOW PRESSURE IS MOVING EAST OVER THE RIO GRANDE.
WITH HIGH PRESSURE SLIDING ACROSS THE HIGH PLAINS AND OVER TO MINNESOTA. DYNAMIC UPPER CLOSED LOW PRESSURE SYSTEM WILL LIFT NORTH INTO TEXAS TODAY THEN INTO MISSOURI ON MONDAY. STRONG CANADIAN HIGH PRESSURE OVER THE NORTH WILL BE BATTLING THE MOISTURE ADVECTION AS IT SURGES NORTH. A MIX CENTRAL WITH THE MAJORITY SNOW THEN A MIX WITH A PERIOD OF FREEZING RAIN AND POTENTIAL FOR SIGNIFICANT ICING FAR SOUTHEAST. STRONG AND GUSTY WINDS WILL ENHANCE THE HEAT TRANSFER AND FREEZING PROCESS THAT MAY LEAD TO SIGNIFICANT ICING. CENTRAL IA INCLUDING THE DSM METRO MAY ALSO HAVE FREEZING RAIN UP TO ONE TENTH INCH AND A PERIOD OF SLEET. PTYPE IN QUESTION LATE IN THE EVENT WITH POSSIBLE LOSS OF ICE AND POSSIBLY A PERIOD OF FREEZING DRIZZLE MONDAY NIGHT.
257 PM CST SUN DEC 27 2015 TRACK AND INTENSITY OF SOUTHERN PLAINS STORM SYSTEM AND RESULTANT SNOWFALL WILL BE THE MAIN FORECAST CHALLENGE AS THE SYSTEM LIFTS ACROSS THE LOWER MISSOURI VALLEY ON MONDAY.
A DEEP CLOSED UPPER LEVEL LOW WILL LIFT FROM FAR WEST TX TO NORTHEAST TX BY LATE THIS EVENING. STRONGLY DIFFLUENT FLOW WILL MOVE INTO THE LOWER MS RIVER VALLEY LATE TONIGHT. EXPECT HEAVY RAIN TO INITIALLY FOCUS NORTH OF A COLD FRONT THAT WILL SAG TO NEAR THE I40 CORRIDOR OVER THE MIDSOUTH LATER TODAY. THE COLD FRONT WILL RETURN NORTH AS A WARM FRONT. EFFECTIVELY PLACING ALL OF THE MIDSOUTH IN THE LOW LEVEL WARM SECTOR. THE LOW LEVEL INVERSION BEGINS TO ERODE AND STORMS BECOME ROOTED NEAR THE SURFACE. WITH COOLER AND DRIER LOW LEVEL AIR SPREADING IN FROM THE SOUTHWEST.
DRIER AIR ALOFT WORKING INTO THE UPPER-LEVEL LOW PRESSURE SYSTEM TO OUR SOUTH HAS KEPT SNOWFALL LIGHT AND PATCHY THIS MORNING. /ISSUED 433 AM CST SUN DEC 27 2015/ EARLY THIS MORNING WATER VAPOR IMAGERY SHOWED A CLOSED LOW CENTERED JUST SOUTHWEST OF EL PASO DRIFTING SLOWLY TO THE SOUTHEAST. DEEP MOISTENING ON THE NORTHWEST/WEST SIDE OF THE CLOSED LOW (WESTERN EXTENT OF TROWAL) LATER IN THE DAY AND INTO TONIGHT SHOULD PERSIST AND GIVE MUCH OF THE AREA ADDITIONAL ACCUMULATION. AS THE SYSTEM DEPARTS EARLY MONDAY ANOTHER UPPER TROUGH WILL DIG SOUTHWARD ALONG THE WEST COAST AND INTO THE SOUTHWEST.
FOR MOST OF THE AREA THERE WAS SOME WARMING TODAY AND LOWS TONIGHT SHOULD BE WARMER. THIS IS NOT SO MUCH THE CASE IN THE LOWER ELEVATIONS OF GRAND AND JACKSON COUNTIES WHERE SOME SPOTS ARE STILL BELOW ZERO AT THIS TIME. A WEAK DENVER CYCLONE SHOULD BRING A WEAK DRIFT OF COOLER AIR TOWARD DENVER LATE TONIGHT. SO IF THERE IS A BETTER DEVELOPED FOG BANK THEN WE COULD HAVE WIDESPREAD DENSE FOG WRAPPING AROUND THE CYCLONE CIRCULATION. FOR MONDAY THE HIGHER CLOUDS SHOULD SHIFT TO THE EASTERN BORDER.
AS THE MID TO UPPER LOW SWINGS ENE. THE LOW WILL BEGIN TO LIFT TO THE NORTH LATE TONIGHT OVER NORTH TEXAS. AND SOME FREEZING RAIN WILL OCCUR. SOME ICE ACCUMULATION IS STILL EXPECTED THROUGH EARLY TOMORROW MORNING, ESPECIALLY ACROSS CENTRAL/SOUTH CENTRAL OK WHERE WARMER NOSE AT 700 MB WILL NUDGE IN AROUND THE LOW. THE LOW WILL QUICKLY EXIT OUR REGION TO THE NE BY 18Z TOMORROW, BUT TRAIL SOME PATCHY SNOW/BLOWING SNOW ACROSS CENTRAL AND NORTHERN OK PERHAPS THROUGH LUNCHTIME. BASED ON THIS, AND MOISTURE PROFILES ACROSS NORTHERN OK, DECIDED TO BUMP POPS INTO THE HIGH CHC CAT TUE NIGHT.
AN UPPER LEVEL RIDGE WILL REMAIN IN PLACE ALONG THE EASTERN SEABOARD TODAY. A BACK DOOR COLD FRONT IS EXPECTED TO TRACK SOUTHWARD THROUGH VIRGINIA INTO CENTRAL NORTH CAROLINA ON MONDAY. AS CANADIAN HIGH PRESSURE SHIFTS INTO NORTHERN NEW ENGLAND AND EXTENDS SOUTHWARD ALONG THE MID-ATLANTIC COAST. THE STRONG RIDGE OFF THE SOUTHEAST COAST WILL CONTINUE TODAY BUT BEGIN RELAXING TONIGHT WITH FALLING HEIGHTS. A SFC COLD FRONT BEING PUSHED SOUTHWARD BY A S/W CROSSING NEW ENGLAND WILL ADVANCE TOWARD THE NC/VA BORDER. MODELS HAVE CONSISTENTLY FORECAST THE CAD TO SCOUR RAPIDLY LATE MONDAY NIGHT AHEAD OF AN APPROACHING WEAK COLD FRONT.
TEMPERATURES TONIGHT SHOULD RESPOND BY FALLING GENERALLY INTO THE LOW TO MID 20S FOR MOST LOCATIONS. A LOW PRESSURE SYSTEM OVER ALBERTA WILL DIVE SOUTHEAST INTO THE FORECAST AREA WEDNESDAY. P-TYPE COULD END UP BEING AN HOUR OR TWO OF LIGHT FREEZING RAIN BEFORE SURFACE TEMPS WARM UP TO ABOVE FREEZING.
