IT DOES APPEAR AS THOUGH ALL OF OUR PARISHES NOW ARE NORTH OF THE COLD FRONT. /ISSUED 528 PM CST SAT NOV 28 2015/ THE COLD FRONT HAS MOVED SLOWLY ACROSS MOST OF THE AREA. /ISSUED 401 PM CST SAT NOV 28 2015/ A WET FORECAST WILL PREVAIL IN THE SHORT TERM WITH A SLOW MOVING COLD FRONT CONTINUING TO MEANDER ITS WAY ACROSS NORTH CNTRL LA.
TEMPERATURES WILL NEED A BIT OF ADJUSTMENT TO CONTEND WITH THE AFOREMENTIONED DRIER AND COOLER AIR TO THE NORTH. THIS WILL BE DUE TO THE FURTHER SOUTHWARD MOVEMENT OF THE FRONT AND A BIT OF A STRONGER PUSH FROM THE COOLER AND DRIER AIR TO THE NORTH. MODELS ARE NOW SHOWING A SLOWER PROGRESSION OF THE NEXT SYSTEM AS A WEAK RIDGE DEVELOPS OVER THE AREA MONDAY IN REACTION TO THE DEEPENING LOW OVER THE CENTRAL US.
DECREASED RAIN CHANCES SLIGHTLY NORTHWEST OVERNIGHT WITH THE HIGHEST POPS CONFINED TO THE FEW FAR NORTHWEST COUNTIES.
AM GOING WARMER THAN TODAY. BUT STILL GOING ONLY AROUND 60 DEGREES INLAND AREAS (COULD BE WARMER ESPECIALLY NEAR THE COAST IF THE FRONT STARTS MOVING INLAND BEFORE THE END OF THE AFTERNOON). GOING ON THE LOW SIDE OF GUIDANCE. COASTAL TROUGH DEVELOPS ON MONDAY (WITH BOUNDARY EXPECTED TO STAY OFFSHORE).
SLOW SOUTHWARD CRAWL OF OUR CURRENT COLD FRONT HAS THE FRONT ALREADY THROUGH KCKV AND JUST NORTH OF KBNA AT ISSUANCE.
COLD FRONT NOW THRU AEX/LCH. /ISSUED 804 PM CST SAT NOV 28 2015/ ADJUSTED HOURLY TEMPERATURES TO ACCOUNT FOR COOLER AIR FILTERING A LITTLE FASTER BEHIND THE FRONT ACROSS SOUTHEAST TEXAS AND EXTENDING INTO SOUTHWEST AND CENTRAL LOUISIANA. LOOKS LIKE WE ALSO NEEDED TO ADJUST THE LOWS TONIGHT ALONG AND WEST OF AN ALEXANDRIA TO LAKE CHARLES LINE. LARGE UPPER TROUGH IS PROGGED TO SLOWLY TRANSLATE THROUGH THE CENTRAL PLAINS THROUGH THE WEEK.
WILL KEEP AN EYE ON THE THE POTENTIAL FOR FOG AND VERY LIGHT FREEZING DRIZZLE MAINLY ALONG AND EAST OF THE LARAMIE RANGE AND INTO THE NEBRASKA PANHANDLE. BUT WITH SHALLOW MOISTURE AND -5 C TO -10 C TEMPERATURES CAN NOT COMPLETELY RULE OUT SOME POCKET OF PATCHY FREEZING DRIZZLE TONIGHT. THERE IS THE POTENTIAL FOR PATCHY FOG ALONG THE CHEYENNE RIDGE AFTER MIDNIGHT. MODELS HAVE COME INTO BETTER AGREEMENT WITH A PARCEL OF MIDLVL ENERGY SWINGING SOUTH ALONG SOUTHERN COLORADO AND PUSHING THE LOW PRESSURE SYSTEM ACROSS WYOMING INTO NEBRASKA BY MONDAY AFTERNOON.
217 AM EST SUN NOV 29 2015 WEAKENING HIGH PRESSURE WILL REMAIN IN THE FORECAST AREA THROUGH TODAY. A DIFFUSE COLD FRONT WILL MOVE INTO THE AREA TONIGHT AND STALL.
THE OVERALL FORECAST IS JUST AS IT HAS BEEN FOR THE LAST COUPLE OF DAYS WITH HIGH PRECIPITABLE WATER CONTENT IN THE ATMOSPHERE AND A SLOW MOVING FRONT THAT IS NOT BEING PUSHED BY THE UPPER LEVEL LOW THAT IS JUST ABOUT STATIONARY OVER THE GREAT BASIN. THE UPPER LOW WILL MOVE TO THE EAST BEGINNING ON SUNDAY AND THIS WILL ALLOW FOR A MORE ZONAL FLOW OVER THE MID-SOUTH AND THUS WILL PUSH THE FRONT TO THE EAST.
NO CHANGE TO THE REST OF THE FORECAST WITH ANOTHER JET STREAK LEADING THE TROUGH AXIS THIS EVENING. ESPECIALLY THE LOWER LEVEL OVER THE EAST AND FOOTHILLS. SUNDAY'S HIGHS ARE 1-3 C WARMER THAN THIS AFTERNOON'S. ALTHOUGH THERE ARE RATHER SIGNIFICANT DISCREPANCIES AMONGST THE MODELS BEGINNING SUNDAY EVENING REGARDING THE POSITION OF THE UPPER LOW THEY ALL HAVE DECENT QG ASCENT OVER OUR AREA AT THAT TIME AND OVERNIGHT. THIS JUSTIFIES THE HIGH POPS THAT WE HAVE IN THE GOING FORECAST.
UNUSUALLY MILD CONDITIONS CONTINUE AS UPPER LEVEL RIDGE STILL EXTENDS ACROSS THE GULF OF MEXICO AND SOUTHEASTERN UNITED STATES. THIS RIDGE WILL BE GRADUALLY SUPPRESSING SOUTHWARD TODAY AS UPPER LOW ON THE WEST SIDE OF THE ROCKIES PROGRESSES EAST. THIS RIDGE IS BEGINNING TO WEAKEN AND FLOW IS RELAXING BUT OVERALL MOISTURE IS STILL SLIGHTLY INCREASING PER PRECIP WATER VALUES. SURFACE OBSERVATIONS SHOW THAT A COLD FRONT IS CURRENTLY LOCATED ALONG A LINE FROM WEST OF LAFAYETTE TO NATCHEZ AND FURTHER NORTHEAST. THE COMBINATION OF THE UPPER LOW SHIFTING EAST AND UPPER RIDGE SUPPRESSING SOUTHWARD SHOULD ALLOW FOR SLOW PROGRESSION OF THE BOUNDARY AND ASSOCIATED SHOWERS FURTHER SOUTHEAST AND INTO THE CWA. THE UPPER LOW CONTINUE MOVING EAST AT A MORE BRISK PACE MONDAY.
HAVE ADJUSTED POP GRIDS TO ACCOUNT FOR FREEZING DRIZZLE FORMING ALONG A LINE FROM CLARENDON TO MIAMI AND EASTWARD. FREEZING FOG IS SHOWING SIGNS OF FORMING ACROSS THE COMBINED PANHANDLES THIS EVENING AND HAVE CONTINUED THE PRESENT FREEZING FOG ADVISORY. CAUSING FREEZING FOG MAINLY AT KDHT AND KAMA. FREEZING FOG ADVISORY UNTIL 9 AM CST SUNDAY FOR THE FOLLOWING ZONES: ARMSTRONG. FREEZING FOG ADVISORY UNTIL 9 AM CST SUNDAY FOR THE FOLLOWING ZONES: BEAVER.
ROTATING AROUND THE STATIONARY UPPER LOW THAT WAS CENTERED OVER NV/UT. MADE A FEW ADJUSTMENTS TO THE LOWS BASED ON THE OBSERVED TRENDS AND EXPECTED CLOUD COVER OVER THE SE AND KSHR AREA. NEW 00Z MODELS MOVE THE UPPER LOW SLOWLY E THROUGH MON WITH LIMITED MOISTURE THROUGH THE PERIOD.
