1036 AM CST FRI DEC 18 2015 SKY CLEAR WITH A VERY SLUGGISH WARM UP ANTICIPATED THIS MORNING AS THE AREA IS UNDER THE INFLUENCE OF A DRIER AND COOLER AIR MASS IN RELATION TO YESTERDAY. /ISSUED 500 AM CST FRI DEC 18 2015/ COLD FRONT JUST MOVED OFF THE COAST BETWEEN 3 AND 4 AM WITH BUBBLE OF HIGH PRESSURE PUSHING INTO COLLEGE STATION/CROCKETT AREA WHICH HAS BUMPED UP WINDS AND IS PUSHING IN DRIER AIR. TONIGHT AND SATURDAY HIGH PRESSURE MOVES INTO LA/MS AND WINDS ACROSS THE REGION BECOME MORE EASTERLY THEN SOUTHEASTERLY WHICH WILL MEAN A SLOW RETURN OF GULF MOISTURE THIS WEEKEND.
150 PM PST FRI DEC 18 2015 A COLD FRONT WILL BRING RAIN TO THE AREA LATER TONIGHT AND SATURDAY. WEAK COLD FRONT APPROACHING THE AREA FROM THE NORTHWEST WILL LOOK AND FEEL A LOT LIKE THE OTHERS SO FAR THIS WINTER.

AN UPPER TROUGH AND JET WILL REMAIN TO THE NORTH AND WEST OF THE AREA KEEPING SOME HIGH CLOUDS AROUND. MAINLY IN THE LOWER TO MID 60S. SKIES WILL BE CLEAR AND GRADUAL DECOUPLING WILL RESULT IN LOW TEMPS NEAR FREEZING IN SOME COLDER INLAND AREAS TO THE MID 30S ALONG THE U. CLEAR SKIES AND LIGHT WINDS WILL SUPPORT STRONG RADIATIONAL COOLING AND LOW TEMPS IN THE LOWER TO MIDDLE 30S MOST PLACES AWAY FROM THE IMMEDIATE COAST.
251 PM CST FRI DEC 18 2015 SUB-ZERO LOWS TONIGHT CENTRAL AND A WARMER DAY SOUTHWEST ON SATURDAY HIGHLIGHT THE SHORT TERM FORECAST.
EXPECT ADDITIONAL MOUNTAIN SNOW AND VALLEY RAIN ON SATURDAY AS A PACIFIC COLD FRONT CROSSES THE AREA.
BASED ON THE UPGRADED CONDITIONS AND WARMER TEMPS. THE WARM UP WILL CONTINUE INTO SATURDAY AS AN UPPER LEVEL RIDGE BUILDS OVER THE WESTERN US.
AN UPPER LEVEL TROUGH CAN BE SEEN ON SATELLITE TRAVERSING THE MISSISSIPPI AND OHIO RIVER VALLEY REGIONS. WITH A SURFACE COLD FRONT PUSHING SOUTH THROUGH TEXAS IN ITS WAKE. THE RIDGE WILL SCOOT EAST OF THE AREA LATER IN THE DAY. AN UPPER RIDGE WILL BUILD OVERHEAD TODAY AS THE TROUGH HEADS FOR THE EAST COAST. BUT TEMPERATURES WILL STILL HAVE A HARD TIME CLIMBING ABOVE THE 50S FOLLOWING LAST NIGHT/S COLD FRONT. RURAL LOCATIONS COULD REACH THE FREEZING MARK AGAIN BY SUNRISE SATURDAY.
STRONG CAA IS KEEPING NORTHWEST WINDS GUSTY AND WIND CHILLS HOVERING DOWN AROUND THE FREEZING MARK. HIGH TEMPERATURES AREAWIDE WILL MAX OUT IN THE LOW TO MID 40S THIS AFTERNOON. /ISSUED 407 AM CST FRI DEC 18 2015/ A COLD FRONT WILL CONTINUE TO PROGRESS SOUTHEASTWARD ACROSS THE MID SOUTH TODAY BRINGING A PERIOD OF CLOUD COVER THIS MORNING TO MUCH OF THE REGION.

1230 PM CST FRI DEC 18 2015 THE HIGH RESOLUTION GUIDANCE HAS HAD A DIFFICULT TIME PICKING UP ON THE SHALLOW STRATUS ACROSS WESTERN AND SOUTH CENTRAL NORTH DAKOTA THIS MORNING. THE MAIN CHALLENGE FOR THE SHORT TERM IS TIMING FOR THE LOWER CLOUDS AND LIGHT SNOW/FLURRIES WILL MOVE OUT OF WESTERN AND CENTRAL NORTH DAKOTA. AN UPPER LEVEL RIDGE AXIS PUSHES EAST OUT OF THE ROCKIES AND INTO THE WESTERN PLAINS. WARM AIR ADVECTION CONTINUES INTO SATURDAY AS RIDGE AXIS PASSES OVER WHICH WILL BRING MILDER TEMPERATURES. SO WILL KEEP POPS ON THE LOWER SIDE.
1201 PM EST FRI DEC 18 2015 LOW PRESSURE WILL EXIT ACROSS THE MARITIMES TODAY. A NEARLY STATIONARY FRONTAL BOUNDARY WILL REMAIN ACROSS THE GULF OF MAINE THIS AFTERNOON WHILE LOW PRESSURE MOVES NORTHEAST ALONG THE FRONT. THE LOW IS FORECAST TO PASS ACROSS SE NOVA SCOTIA TONIGHT. THE HIGH RESOLUTION MODELS SUCH AS THE HRRR 3KM AND ARW SHOWING SOME MORE PRECIP MOVING NE W/THE BULK ACROSS EASTERN WASHINGTON COUNTY. GUSTY WEST WINDS CAN BE EXPECTED SATURDAY AS LOW PRESSURE EXITS THROUGH THE CANADIAN MARITIMES AND HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST.
BRIEF SHOT OF COOLER AND DRIER WEATHER THIS WEEKEND. CONVECTION ASSOCIATED WITH THE PRE- FRONTAL TROUGH HAS ALREADY PUSHED OFF MOST OF THE EAST COAST LATE THIS AFTERNOON AND WILL BE CLEARING THE FAR SOUTHERN END OF MIAMI- DADE COUNTY IN THE NEXT HOUR. ACTUAL COLD FRONT IS APPROACHING LAKE OKEECHOBEE WITH THE DRY AIR NOT TOO FAR BEHIND WITH DEWPOINTS IN THE MID 30S INTO NORTH CENTRAL FL, AND 40S AND 50S IN CENTRAL FL. HIGH PRESSURE BUILDS IN BEHIND THE FRONT WITH THE CENTER SLIDING ACROSS THE DEEP SOUTH AND MID-ATLANTIC THROUGH THE WEEKEND. POSITION OF THE HIGH WILL MEAN WINDS VERY QUICKLY VEER EAST-NORTHEAST, AND THE FRONT WILL STALL A LITTLE CLOSER TO HOME THAT PREVIOUS FORECAST HAVE INDICATED, MORE OVER THE FL STRAITS AND NW BAHAMAS.
A RIDGE ALOFT WILL SHIFT ACRS THE AREA SAT. SETTLING E OF THE AREA BY DAYBREAK SUN WHILE A MODEST LONGWAVE TROF AXIS MOVES THRU THE CENTRAL PLAINS TWD THE MISS RIVER. MODEL TRENDS HAVE SHOWN A DEEPENING WARM BLYR WHICH LOOKS TO BE ENOUGH TO TRANSITION THE PRECIP BEFORE HITTING A SUB-FREEZING GROUND. SUBTLE COLD FRONT MOVING ACROSS SRN MN AND INTO WRN WI HAS HAD A CONVECTIVE SNOW BURST OUT AHEAD OF IT THAT HAS BROUGHT ABOUT 30 MINUTES OF SNOW HARD ENOUGH TO GET IFR VIS.
104 PM EST FRI DEC 18 2015 AN UPPER LEVEL TROUGH WITH WEAK EMBEDDED DISTURBANCES WILL MOVE ACROSS THE GREAT LAKES AND OHIO VALLEY THROUGH TONIGHT. HIGH PRESSURE WILL BUILD INTO THE REGION ON SATURDAY.
THIS SHOULD KEEP HIGHS FROM REACHING THE LOWER 40S IN MANY LOCATIONS NEAR THE TN RIVER AND POINTS NORTH. THESE CLOUDS ARE ASSOCIATED WITH A COLD FRONT THAT WILL MOVE THROUGH THE REGION THIS MORNING.
147 PM CST FRI DEC 18 2015 Flat upper ridging over the region today will transition to southwesterly Saturday ahead of the next ua trough.

1025 AM PST FRI DEC 18 2015 Cold frontal system moves into northern California today bringing much wetter pattern with rain and mountain snow across the whole north state by this evening. Elsewhere, the satellite indicates the trough is digging off the coast and the models have caught onto this trend as well. Satellite and radar imagery showing Pacific cold front just moving on to the north coast at this time and progged fairly well by short range models. main upper trough will be moving on to the coast by Saturday morning keeping precipitation going over most of the cwa through the morning hours.
A COLD FRONT APPROACHING THE AREA WILL MAINTAIN LIGHT RAIN OVER THE NORTH BAY TODAY. THE CURRENT VISIBLE SATELLITE IMAGE IS SHOWING A WELL DEFINED COLD FRONT PUSHING THROUGH NORTHERN CALIFORNIA. RELATIVELY WARM SOUTHERLY WINDS ARE BLOWING AHEAD OF THE FRONT WITH COOLER WEST NORTHWESTERLY WINDS BEHIND THE FRONT. THIS SECOND STORM SYSTEM IS THE PARENT LOW OF THE COLD FRONT THAT IS MOVING THROUGH NORTHERN CALIFORNIA.
THIS HAS RESULTED IN A QUICK TRANSITION TO SOUTHERLY WINDS IN THE LOW LEVELS. THESE LIGHT SOUTH WINDS WILL CONTINUE INTO TONIGHT AND HELP TO KEEP TEMPS A FEW DEGREES WARMER THAN LAST NIGHT IN MOST AREAS WITH LOWS GENERALLY IN THE LOW TO MID 30S.
RATHER BENIGN CONDITIONS WILL CONTINUE OVER SOUTH TEXAS THROUGH TOMORROW AS A RIDGE OF HIGH PRESSURE REMAINS PARKED OVER THE AREA. HIGHS WILL CLIMB INTO THE LOWER TO MIDDLE 70S ACROSS THE REGION TOMORROW. THE RIDGE OF HIGH PRESSURE WILL BEGIN TO PUSH TO THE EAST.
