THE COLD FRONT WAS ON THE WFO DOORSTEP THIS MORNING AT THE TIME OF RELEASE. WHERE FOG WAS ABLE TO FORM SOUTH OF THE COLD FRONT. WINDS WERE FROM THE NORTHWEST IN THE LOWER LEVELS AND THEN FROM THE WEST-NORTHWEST THROUGH THE REMAINDER OF THE TROPOSPHERE. /ISSUED 429 AM CDT SAT OCT 10 2015/ COLD FRONT. WEAK COLD AIR ADVECTION WILL RESULT IN HIGHS A FEW DEGREES COOLER THAN THE LAST FEW DAYS. EXPECT HIGHS TO TOP OUT IN THE LOW TO MID 80S.
THANKS TO A BROAD STRATOCU DECK SPREAD ACROSS THE REGION IN THE WAKE OF LAST NIGHT'S COLD FRONTAL PASSAGE. EARLY MORNING WATER VAPOR IMAGERY SHOWED A MID LEVEL TROF MOVING AWAY FROM THE AREA TAKING THE SHOWER ACTIVITY WITH IT. LOW LEVEL CLOUDINESS ASSOCIATED WITH A LOW LEVEL THERMAL TROF WAS DEVELOPING SOUTHWARD ACROSS THE AREA. TEMPERATURES WILL REBOUND ON SUNDAY AS THE THERMAL TROF PULLS EAST.
12 UTC surface analysis showed a cold front moving across Southwestern Georgia and the Florida Panhandle. The drier (and slightly cooler) air is lagging the front by quite a bit and is located back across Western AL and MS. Though the initial batch of showers with the front are moving out of the area, some of the models generate a few showers this afternoon, mainly ahead of a piece of energy rotating around the base of the trough.
A WEAK COLD FRONT HAS MOVED ACROSS THE SOUTHEAST TEXAS TERMINALS EARLY THIS MORNING. A WEAK COLD FRONT EXTENDED FROM ABOUT KLFT TO KIAH TO KCOT. LEANED TOWARD THE WARMER NAM/ECMWF GUIDANCE FOR TEMPS DUE TO THE WARMER START TO THE DAY AND DRY ADVECTION. LOWS ON SUNDAY MORNING SHOULD BE A FEW DEGREES COOLER THAN THIS MORNING. UPPER LEVEL RIDGING REMAINS IN PLACE ON SUNDAY WITH 500 HEIGHTS BUILDING TO 589 DM SO ANOTHER VERY WARM DAY IS EXPECTED. HAVE AGAIN LEANED TOWARD THE WARMER NAM/ECMWF GUIDANCE.
A MID LEVEL RIDGE WILL BUILD OVER THE AREA TODAY WITH TEMPERATURES WARMING BACK INTO THE LOWER 90S FOR INLAND AREAS. BROAD RIDGING DEVELOPS OVERHEAD BETWEEN THE RETROGRADING CUT OFF LOW MOVING WEST ACROSS BAJA CALIFORNIA AND THE MID LEVEL TROUGH SWING SOUTH THROUGH THE DEEP SOUTH. THE ASSOCIATED SURFACE FRONTAL BOUNDARY WITH THE TROUGH TO THE EAST CONTINUES TO SLOWLY PUSH FARTHER SOUTH INTO THE REGION WITH DRIER AIR AND LIGHT AND VARIABLE WINDS. TEMPERATURES SHOULD BE WARMER COMPARED TO YESTERDAY. WITH HIGHS GENERALLY IN THE LOWER 90S.
925 AM EDT SAT OCT 10 2015 HIGH PRESSURE WILL REMAIN OVER THE REGION THROUGH SUNDAY.
1047 AM CDT SAT OCT 10 2015 High pressure building back into the region today. Light northerly winds, then variable as the ridge axis moves over Central Illinois. Sunny and dry conditions can be expected today as high pressure moves across the area. By afternoon, the high pressure should be east enough of the area to allow southerly winds to return. Temperatures will be a roller-coaster ride over the next few days, before the upper pattern transitions to a more persistent northwest flow and a steadier period of cooler temperatures mid to late week.

LINGERING CLOUD COVER AND COLD ADVECTION WILL KEEP TEMPERATURES SOMEWHAT COOL ACROSS THE NORTH WITH HIGHS IN THE LOWER TO MID 70S.
/issued 333 AM CST WED JAN 27 2016/ (Today and Tonight) Skies were clear early this morning over all except the southwestern part of our area (southwest of a Barnhart to Sonora line), where patchy low clouds and freezing fog were observed. Given the light rain and snow which occurred across that area late yesterday afternoon and evening, along with temperatures slightly below freezing early this morning, may have some slick spots on roads, especially bridges and overpasses. The low clouds and fog will dissipate around mid-morning, with mostly sunny skies expected through the day today. Temperatures will be cool again today, but with sunshine highs will be 8-12 degrees warmer than yesterday. Farther north across the Big Country, lows are expected to be in the lower to mid 30s as southwest winds will develop and limit the temperature drop.

236 PM CST WED JAN 27 2016 The upper trough that was over the area yesterday has begun to move southeastward. Temperatures are expected to be a little warmer than yesterday with highs in the 50s across a large portion of the area today. Since mostly clear skies, light winds, and freezing temperatures are expected tonight, freezing fog will be possible across portions of the CWA Thursday morning. Forecast soundings and the NAM12 surface humidity values are not indicating widespread fog so will not issue a Dense Freezing Fog Advisory at this point but will add in patchy freezing fog to the grids. Temperatures will warm up even further on Thursday as upper ridging starts to develop across the area.
BOTH WERE DIGGING QUICKLY SOUTHEASTWARD COMING DOWN A HIGHLY AMPLIFIED RIDGE OVER WESTERN NORTH AMERICA.
OCCASIONAL SNOW SHOWERS WILL BRING A LIGHT SNOW ACCUMULATION TO FAVORED AREAS DOWNWIND OF LAKE ERIE AND OVER THE HIGHER TERRAIN OF SOUTHWEST PENNSYLVANIA BY THE END OF THE WEEK. HIGH PRESSURE BUILDING OVER THE LOWER OHIO VALLEY THROUGH TONIGHT WITH NORTHWEST FLOW SHIFTING TO THE WSW OVERNIGHT. A LIMITED DURATION FETCH SHOULD SPELL ONLY LIGHT SNOW ACCUMULATIONS /1-3 INCHES/ FCST FROM THE NW ALLEGHENIES TO THE SOUTHWEST LAUREL RIDGES THU NGT AND FRI. ALSO CANT RULE OUT A DUSTING EAST OF THE HIGHER TERRAIN ACROSS THE CENTRAL VALLEYS UNDER THE UPPER TROUGH.

312 PM CST WED JAN 27 2016 NORTHWEST FLOW/FAVORABLE MIXING CONDITIONS REMAIN ACROSS THE REGION INTO THE OVERNIGHT SO WINDS WILL STAY UP ENOUGH TO KEEP TEMPERATURES FROM BOTTOMING OUT AND FOG FROM FORMING DESPITE DEWPOINTS IN THE LOW 30S. THESE LESS FAVORABLE MIXING CONDITIONS WILL RESULT IN TEMPERATURES SOMEWHAT COOLER THAN TODAYS.
215 PM EST WED JAN 27 2016 A SERIES OF LOW PRESSURE CENTERS WILL MOVE NORTHEASTWARD ALONG A FRONTAL ZONE NEAR THE SOUTHEAST COAST. DRY HIGH PRESSURE WILL DOMINATE OVER THE WEEKEND. THE HIGH-RESOLUTION MODELS DISPLAYED SCATTERED COVERAGE DURING MUCH OF THE NIGHT.
THE LOW LEVELS ARE QUITE DRY SO ANY PRECIPITATION WITHIN THIS BAND OF CLOUDS SHOULD REMAIN ALOFT. AS A COLD FRONT DROPS INTO THE AREA. BRISK NORTHWEST WINDS WILL BRING SOMEWHAT COOLER TEMPERATURES BUT THE BRUNT OF THE COLDEST AIR SHOULD REMAIN EAST OF THE DVN CWA. LOW STRATUS IS EXPECTED TO BE OVER THE AREA FOR MUCH OF THE DAY WITH MODELS INDICATING A CYCLONIC FLOW DUE TO A DEEP TROUGH IN THE GREAT LAKES. A SPOKE OF ENERGY ROTATING AROUND THIS TROUGH MAY BRUSH OUR FAR NW IL COUNTIES AND HAVE INTRODUCED A SLIGHT CHANCE FOR LIGHT SNOW.
A weak downslope component to the low-level flow will allow for even warmer conditions on Thursday.
DEEP UPPER TROUGH WITH A POSITIVE TILT CONTINUES TO PULL SSE WITH CLEARING SKIES IN ITS WAKE OVER SOUTH CENTRAL TX. FREEZES ARE LIKELY OVER MANY LOCATIONS AND SOME SLIGHTLY WARMER THAN FREEZING CONDITIONS OVER THE HIGHER TERRAIN LOCATIONS THAT CAN CATCH A SLIGHT MIXING OF THE WESTERLY BOUNDARY LAYER WINDS.
