410 AM CST WED DEC 30 2015 WARM MOIST AIR OVERRIDING THE COOLER SURFACE HAS LED TO CLOUDS THICKENING AND PERIODS OF RAIN OVERNIGHT THAT HAS MOVED FROM THE COASTAL AREAS WELL NORTH INTO INTERIOR SOUTHEAST TEXAS AND CENTRAL LOUISIANA. TEMPERATURES WERE FAIRLY CONSISTENT ACROSS THE COUNTY WARNING AREA IN THE UPPER 40S NORTH TO THE LOWER 50S SOUTH. BROAD UPPER LEVEL TROUGHING IN THE CENTRAL AND WESTERN UNITED STATES HAS RESULTED IN SOUTHWESTERLY FLOW ALOFT OVER OUR AREA.
A LOW PRESSURE CENTER WILL DEVELOP ALONG THE FRONT ON THURSDAY.
Currently have areas of freezing fog across portions of southeast New Mexico and northern Permian Basin early this morning. /issued 537 AM CST WED DEC 30 2015/ Freezing fog has developed over portions of Southeast New Mexico and across the northern portions of the Texas Permian Basin. freezing fog could persist through mid morning across these areas before making way to mostly sunny conditions. The central and southern portions of the Permian Basin will likely see some patchy freezing fog. Today's high temperatures should be slightly warmer than yesterday's.
521 AM CST WED DEC 30 2015 /12Z TAFS/ Light winds and residual low-level moisture from snow/snow melt has allowed patchy freezing fog to develop this morning. /issued 403 AM CST WED DEC 30 2015/ (Today and tonight) Temperature and dewpoint spreads have dropped to near zero early this morning, and still think that patchy fog and freezing fog will develop by sunrise.
505 AM CST WED DEC 30 2015 SOUTHERLY FLOW HAS ALLOWED ENOUGH MOISTURE ADVECTION TO OCCUR IN THE LOW LEVELS THAT FREEZING DRIZZLE STARTED IN THE EARLY OVERNIGHT HOURS OVER PORTIONS OF THE SOUTHERN AND EASTERN TEXAS PANHANDLE AND THE EASTERN OKLAHOMA PANHANDLE. THIS HAS NOW GIVEN WAY TO FREEZING FOG. THE LACK OF SUN FOR A GOOD PORTION OF THE DAY WILL LIMIT DAYTIME HEATING AND KEEP THE PANHANDLES SLIGHTLY COOLER TODAY THAN YESTERDAY. THURSDAY WILL ALSO BE CHILLY AS CLOUD COVER HANGS AROUND FOR ANOTHER DAY DUE TO A LEE SIDE TROUGH BUILDING INTO THE WESTERN PORTION OF THE PANHANDLES.
A STALLED FRONT TO OUR WEST AND NORTHWEST ALONG WITH DEEP LAYER RIDGING OVER THE ATLANTIC THAT REACHES ACROSS THE STATE WILL MAINTAIN A WARM AND MOIST SOUTHEAST TO SOUTHERLY FLOW.

305 PM CDT SUN OCT 11 2015 Low pressure system currently over the western high plains this afternoon deepens eastward tonight. Occasionally gusty south winds ahead of the wave will wane to near 10 mph as a cold front passes southeast through the CWA overnight. Dry and cold air advection filters through the area, keeping highs at least 10 degrees cooler than today in the mid to upper 70s. Consensus would have dewpoints mixing down to the 30s, perhaps a few upper 20s across north central KS, resulting in minimum RH values from the low to middle 20 percent range.
AFTER NEAR RECORD TO RECORD TEMPS THIS AFTERNOON WE WILL SEE A MILD OVERNIGHT ACROSS WEST TEXAS BEFORE THE COLD FRONT LIMITS MONDAYS HIGHS TO THE MID TO UPPER 70S ON THE CAPROCK AND 80S TO THE EAST INTO THE ROLLING PLAINS. DRIER AIR BEHIND THE COLD FRONT WILL BRING ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS. A SLOWLY PROGRESSIVE UPPER PATTERN WILL SEE UPPER LEVEL RIDGING OVER THE WRN CONUS AT THE START OF THE WEEK SHIFT EWD TO ROCKIES BY MIDWEEK THEN TO THE SRN PLAINS BY WEEKS END. ALTHOUGH WEAKENING BY THAT TIME AS AN UPPER LOW LOCATED OFF THE BAJA COAST THIS AFTN MOVES NWD THEN ONTO THE SRN CALIF COAST BEFORE OPENING UP AND MOVING EWD ACROSS THE DESERT SW.

HIGH PRESSURE WILL REMAIN ACROSS WESTERN AREAS WITH A DECENT PRESSURE GRADIENT REMAINING ACROSS NORTHWESTERN SOUTH DAKOTA.
353 PM CDT SUN OCT 11 2015 WINDS AND TIMING OF COLD FRONT WERE THE FOCUS OF THE FORECAST. WENT SLIGHTLY COOLER THAN PREVIOUS FORECAST BUT WAS STILL A DEGREE OR TWO WARMER THAN MOS GUIDANCE FOR MUCH OF THE AREA. WITH STRONG SUBSIDENCE BEHIND BOUNDARY AND COOLER TEMPERATURES PUSHING IN BEHIND UPPER LEVEL LOW ACROSS NORTHERN US. LARGE UPPER LEVEL LOW WILL CONTINUE TO PUSH EAST QUICKLY LEAVING PERSISTENT NORTHWESTERLY FLOW ACROSS MIDWEST THROUGH MAJORITY OF EXTENDED. LATE IN WEEK ANOTHER UPPER LEVEL LOW IS EXPECTED TO PUSH SOUTH ACROSS GREAT LAKES REGION.
227 PM EDT SUN OCT 11 2015 ONE MORE DAY OF WARM TEMPERATURES REMAINS IN THE FORECAST UNTIL A COLD FRONT BRINGS COLDER WEATHER AND A CHANCE FOR SHOWERS. WHEN CLOUDS WILL BEGIN TO INCREASE IN FRONT OF AN APPROACHING COLD FRONT. OVERNIGHT TEMPERATURES WILL BE ABOUT 5 DEGREES WARMER THAN LAST NIGHT. AND DAYTIME HIGHS WILL RISE INTO THE LOW TO MID 70S. AREA WITH THE BEST CHANCE TO RECEIVE RAIN SHOULD BE IN THE SOUTHEASTERN COUNTIES ALONG THE RIDGES. WITH THE UPPER TROUGH LINGERING SLIGHTLY BEHIND THE COLD FRONT.
STLT IS SHOWING THAT THE LOW CLOUDS/FOG CONTINUES TO DECREASE IN COVERAGE. ALSO LOWERED TEMPS TO THE LOW/MID 70S BASED ON TEMPS AT 10 AM. WRAP ARND MOISTURE FROM THE UPPER LOW IN SC WILL PRODUCE A SCT CU FIELD THIS AFTN MAINLY OVER KHSV.
A COLD FRONT WILL MOVE ACROSS THE REGION LATER TONIGHT INTO MONDAY WITH STRONG NORTH WINDS AND DRIER AIR EXPECTED BEHIND THIS FRONT.
A COLD FRONT WILL MOVE ACROSS THE REGION LATE TONIGHT INTO MONDAY MORNING BRINGING STRONG/GUSTY NORTH WINDS BUT NO PRECIPITATION IS EXPECTED.
Temperatures are running a little warmer across the northern Sacramento Valley compared to 24 hours ago, but most other areas of the region are a little cooler today. Gradual warming returns the next few days as strong high pressure covers the region while the closed low remains off the coast of Baja California.

133 PM EDT SUN OCT 11 2015 HIGH PRESSURE OVER THE REGION WILL WEAKEN. A SERIES OF COLD FRONTS WILL SWEEP THROUGH THE GREAT LAKES REGION DURING THE EARLY TO MIDDLE PART OF THE WEEK. REGIONAL SOUNDINGS SHOW VERY LIMITED MOISTURE IN THE LOW AND MID LEVELS ACROSS THE AREA THIS MORNING SO EXPECT LITTLE IN THE WAY OF CLOUD COVER EXCEPT SOME THIN HIGH CIRRUS. WILL SUPPORT TEMPERATURES ABOUT 10F WARMER THAN YESTERDAY. A SERIES OF COLD FRONTS WILL SWEEP ACROSS THE LOWER LAKES FOR THE EARLY TO MIDDLE PART OF THIS WEEK.
Southerly low level flow will result in warmer conditions through Monday. ) keep temperatures several degrees warmer than last night, and (2. It will also be quite breezy given the enhanced pressure gradient in the vicinity of a passing cold front. However, believe the slight chance mention is still warranted given the relatively strong forcing along the cold front. A clearing sky and cooler temperatures will take place Monday night as the cold front sweeps east of the region.
