RECENT MODEL RUNS HAVE SHIFTED MORE CONVECTIVE LOOKING QPF VALUES INTO OUR FAR EASTERN COUNTIES WHILE UPPER LOW PROJECTIONS SHOW A SLIGHTLY MORE SOUTHERLY TRACK. THE FOG AND LOW CEILINGS WILL PERSIST UNTIL A COLD FRONT MOVES THROUGH THE AREA 12Z-16Z. UPPER AIR ANALYSIS THIS MORNING SHOWED A LOW AMPLITUDE RIDGE OVER TEXAS WITH A SHALLOW TROUGH TO THE WEST. A COLD FRONT WAS JUST SOUTH OF OUR CWA AND ANOTHER WAS MOVING THROUGH THE CENTRAL ROCKIES. THE WESTERN UPPER LEVEL TROUGH WILL DEEPEN AND MOVE ACROSS TEXAS DURING THIS PERIOD. THIS WILL BRING THE COLD FRONT FROM THE CENTRAL ROCKIES THROUGH OUR CWA DURING THE DAY THURSDAY.
639 PM EST WED JAN 20 2016 HIGH PRESSURE WILL BUILD ACROSS THE REGION TONIGHT AND THURSDAY AND THEN SHIFT NORTHEAST THURSDAY NIGHT.
658 PM EST WED JAN 20 2016 AVIATION AS SLIGHTLY WARMER AIR MOVES INTO THE AREA TONIGHT INTO THURSDAY THERE WILL BE SOME LIGHT SNOW OVER WESTERN SECTIONS.
631 PM CST WED JAN 20 2016 MVFR CEILINGS THIS EVENING WILL BECOME IFR OVERNIGHT AS ADDITIONAL MOISTURE CONTINUES TO FLOWS IN TO THE AREA AHEAD OF A COLD FRONT THAT WILL ARRIVE EARLY TOMORROW AFTERNOON. FAVORABLE CONDITIONS APPEAR TO BE SETTING UP FOR PATCHY FOG TONIGHT OVER THE NEAR SHORE WATERS AND BAYS AS WARMER/MOIST AIR RETURNS. NEXT IMPULSE OVER THE CENTRAL ROCKIES WILL GAIN AMPLITUDE AS IT OVERSPREADS THE SRN PLAINS TOMORROW AND BRING A STRONGER COLD FRONT THROUGH THE AREA THURSDAY AFTERNOON. ONSHORE FLOW WILL INCREASE OVER SERN TX AND ALLOW CURRENT FRONT OFF THE COAST TO LOSE DEFINITION AS IT LIFTS INLAND AS A WARM FRONT TONIGHT AND TOMORROW. WHICH WILL CHANGE QUICKLY LATE IN THE DAY AS THE COLD FRONT PUSHES THROUGH.
PRECIP HAS TAPERED OFF TO A FEW PATCHES OF VERY LIGHT SNOW AND FREEZING DRIZZLE. AREAS OF FREEZING FOG HAVE DEVELOPED. WILL ISSUE AN SPS TO HIGHLIGHT THE FREEZING DRIZZLE AND FREEZING FOG. CHATTANOOGA AIRPORT, TN 32 43 39 43 / 30 70 90 90 KNOXVILLE MCGHEE TYSON AIRPORT, TN 27 41 36 42 / 30 50 90 90 OAK RIDGE, TN 28 41 36 41 / 30 60 90 90 TRI CITIES AIRPORT, TN 24 42 31 38 / 50 30 80 90 TN.
WE DO HAVE SOME LEFTOVER FLURRIES AND/OR FREEZING DRIZZLE POSSIBLE ON THE BACKSIDE. HOWEVER DID TRANSITION TO AN ADV GIVEN THE POTENTIAL FOR SOME LIGHT FREEZING DRIZZLE.
A PROGRESSIVE TROUGH WILL MOVE DOWNSTREAM OF THE AREA TONIGHT. HIGH PRESSURE ALOFT WILL BECOME ESTABLISHED ACROSS THE REGION FOR THE END OF THE WEEK.
AT 1 PM THE COLD FRONT WAS PUSHING INTO THE I-70 CORRIDOR NEAR THE UT- CO STATE LINE WITH HEAVY SNOW REPORTED NORTH OF THE ROAN- TAVAPUTS PLATEAU. THE EXCEPTION IS THE HIGHWAY 550 UNCOMPAHGRE GORGE WHERE GOOD SNOW ACCUMULATIONS ARE EXPECTED TO MIDNIGHT. CHILLY START TO THURSDAY MORNING WITH NORTHERLY FLOW AHEAD OF DEVELOPING HIGH PRESSURE.
830 PM EST WED JAN 20 2016 THE NEAR TERM SECTION HAS BEEN UPDATED BELOW HIGH PRESSURE WILL MOVE ACROSS INDIANA FROM THE WEST TONIGHT.
IT APPEARS THAT THE LOW VISIBILITIES ARE BRIEF AND WILL COVER WITH NOWCASTS AND A MARINE WEATHER STATEMENT. AREAS OF SEA FOG WILL ALSO BE POSSIBLE AS DEWPOINTS INCREASE NORTHWARD ALONG THE COAST ACROSS RELATIVELY COOLER SEA SFC TEMPS. A STRONG COLD FRONT IS STILL ON TRACK FOR THU. DRIER AND COOLER AIR WILL FILTER FROM W TO E THROUGH THU AFTERNOON/NIGHT WITH CLEAR SKIES BY THU NIGHT. W TO NW WINDS ARE PROGD TO DVLP AND STRENGHEN ACROSS S TX BEHIND THE COLD FRONT THU AFTERNOON.
THE WARM FRONT IS MOVING INTO THE SOUTHERN OREGON WATERS THIS AFTERNOON. THE WARM FRONT WILL SPREAD LIGHT SHOWERS MAINLY INTO THE COASTAL COUNTIES AND NORTHERN DOUGLAS COUNTY. THE WARM FRONT WILL LIFT NORTH OF OUR FORECAST AREA AND DISINTEGRATE WHILE THE COLD FRONT MOVES INTO OUR COASTAL WATERS. THE COLD FRONT IS FORECAST TO STALL IN THE COASTAL WATERS AS THE UPPER LEVEL SUPPORT IS CLOSE TO BEING PARALLEL TO THE FRONT.
930 PM EST WED JAN 20 2016 THE AVIATION SECTION HAS BEEN UPDATED BELOW HIGH PRESSURE WILL MOVE ACROSS INDIANA FROM THE WEST TONIGHT.
THEREFORE WILL LET THE SPS FOR PATCHY DENSE FOG AND FREEZING DRIZZLE/MIST COVER THE CURRENT SCENARIO. CURRENT TEMPERATURES ACROSS THE CWA RANGE FROM THE LOW 20S TO NEAR 30 DEGREES. EXPECT THE LOW CLOUDS ALONG WITH SOME FOG TO REMAIN AS SNOW BEGINS TO DEVELOP OUT WEST. THE MODELS SHOW A SHORT WAVE TROUGH DROPPING IN FROM THE NORTHWEST TONIGHT AND ACROSS THE REGION THROUGH THURSDAY. LIFT FROM THIS TROUGH WILL ENHANCE SNOWFALL ACROSS MUCH OF THE CWA INTO THURSDAY AFTERNOON.
UPDATED SUTIE OF FORECAST PRODUCTS TO MENTION FREEZING FOG ADVISORY THRU 21/15Z WITH SELECTED GRIDS MATCHING ACCORDINGLY. FREEZING DRIZZLE WILL BE POSSIBLE CSV THRU AT LEAST 21/06Z.

A cold front will move through the West Central Texas Thursday morning, resulting in north winds of 15 to 25 knots, with higher gusts. /issued 334 PM CST WED JAN 20 2016/ (Tonight and Thursday) Before another cold front pushes across West Central Texas tomorrow, southwesterly low-level, down-slope flow will help create warmer lows tonight than last night. As another cold front approaches tonight, winds from the southwest will slowly shift and come more from the west by sunrise. This down-slope flow will help maintain lows tonight mainly in the 40 to 45 range; that's much warmer than last night. For tomorrow, colder and drier air will push into and across West Central Texas, as another cold front moves across Texas.
722 PM EST WED JAN 20 2016 HIGH PRESSURE WILL CONTINUE TO CONTROL SOUTH FLORIDA WEATHER TONIGHT KEEPING THE WEATHER DRY AND THE WINDS LIGHT. HIGH PRESSURE OVER THE SOUTHEASTERN UNITED STATES WILL MOVE EASTWARD INTO THE ATLANTIC WATERS TONIGHT INTO THURSDAY,AS LOW PRESSURE OVER THE MISSISSIPPI VALLEY MOVES EAST INTO THE SOUTHEASTERN UNITED STATES. THIS WILL ALLOW FOR THE WIND FLOW OVER SOUTH FLORIDA TO BECOME MORE EASTERLY TONIGHT INTO THURSDAY WHICH IN TURN WILL ALLOW FOR THE TEMPERATURES TO BE WARMER THAN THE LAST COUPLE OF DAYS.
POPS HAVE BEEN DECREASED ACROSS THE NE FOR SNOW TONIGHT WITH THE LIFT AND MOISTURE ASSOCIATED WITH THE MID TO UPPER LOW NOW NORTH OF OUR FA. STILL EXPECT SOME DRIZZLE/FREEZING DRIZZLE TO DEVELOP THERE LATER TONIGHT WITH ISENTROPIC ASCENT.
758 PM CST WED JAN 20 2016 TO ISSUE DENSE FOG ADVISORY, ADD DENSE FOG, FREEZING FOG, ADJUST TEMPERATURE, WINDS, AND DEWPOINT TEMPERATURE FORECAST. CURRENT OBS ARE ALL ABOVE FREEZING BUT SOME OF THE HIGHER ELEVATIONS ARE CLOSE TO FREEZING ESPECIALLY OVER NORTHERN PORTIONS OF SOUTHERN MIDDLE TENNESSEE. SO, HAVE ADDED AREAS OF DENSE FOG TO THE FORECAST AND AREAS OF FREEZING FOG OVER ISOLATED/NORTHERN PORTIONS OF SOUTHERN MIDDLE TENNESSEE WHICH COULD CAUSE SOME SLICK SPOTS OVER AREA ROADWAYS. IN ADDITION, LOWERED POPS AND ISSUED A DENSE FOG ADVISORY FOR THE REST OF THE NIGHT (THROUGH 7 AM) TO ACCOUNT FOR THE DENSE FOG AND POSSIBLY FREEZING FOG. THE TEMPERATURE FORECAST NEEDED SOME SLIGHT ADJUSTMENTS WITH SLIGHTLY 'WARMER' AIR AND DEWPOINT TEMPERATURES OCCURRING OVER NW AL.
548 PM CST WED JAN 20 2016 CONDITIONS TO DETERIORATE TO IFR/LIFR OVERNIGHT AS A WARM FRONT LIFTS NORTH ACROSS THE ARKLATEX BRINGING A CHANCE OF SHOWERS AND ISOLATED THUNDERSTORMS AFTER 21/06Z.

401 PM MST WED JAN 20 2016 CHANCES FOR SNOW WILL CONTINUE THROUGH TONIGHT AS AN UPPER LEVEL TROUGH AND STRONG UPPER JET MOVE ACROSS SOUTHEAST WYOMING. THIS TREND WILL GENERALLY CONTINUE INTO THIS EVENING AS THE GRADIENT DECREASES AND HIGH PRESSURE SHIFTS INTO THE ROCKIES.
EXPECT A NORTHWARD JUMP IN THIS BOUNDARY THURSDAY WHEN THE MID LEVEL TROUGH BEGINS TO APPROACH RESULTING IN GREATER PRESSURE FALLS.
608 PM CST WED JAN 20 2016 AN AREA OF HIGH PRESSURE COVERED THE FORECAST AREA AT 20Z. SOME BR HAD FORMED OVER THE BRAINERD LAKES THANKS TO WARM AIR ADVECTING INTO THE AREA AHEAD OF AN INVERTED SFC TROF OVER THE EASTERN DAKOTAS. THIS COLDER AIR IS ASSOCIATED WITH A WEAK COLD FRONT THAT TRIES TO IMPACT THE REGION. DRIER AIR FROM HIGH PRESSURE ARRIVING FROM THE NW WILL LIMIT ANY SNOW POTENTIAL UNTIL LATE AFTERNOON. ADDED A MENTION OF FLURRIES ACROSS MUCH OF NW WI IN THE AFTERNOON AS THE COLD FRONT DISSOLVES AS IT ATTEMPTS TO MOVE FURTHER SEWD THROUGH THE AREA.
BUT WIDESPREAD FREEZING TEMPERATURES ARE NOT EXPECTED TONIGHT EVEN FOR LEVY COUNTY.
A COLD FRONT WILL APPROACH AND MOVE THROUGH DEEP SOUTH BY LATE THURSDAY RESULTING IN WINDS GUSTY NORTHWEST WINDS. AN UPPER TROUGH OF LOW PRESSURE IS CURRENTLY DEEPENING ACROSS THE CENTRAL PLAINS AND THIS IS SUPPORTING LOW LEVEL SOUTHERLY FLOW WITH ELEVATED DEW POINTS ACROSS DEEP SOUTH TEXAS. THERE ARE NOTICEABLE DIFFERENCES BETWEEN FORECASTED HIGHS IN THE NUMERICAL GUIDANCE ON THURSDAY IN THIS HIGHLY CHANGING EVENT. WILL TREND TOWARD COOLER NAM/GFS HIGHS THAT WILL STILL BE MUCH ABOVE NORMAL. STRONG COLD AIR ADVECTION ASSOCIATED WITH THE FRONT WILL BRING SOMEWHAT BELOW NORMAL OVERNIGHT LOWS THAT WILL BOTTOM OUT IN THE LOWER/MID 40S OVER MUCH OF THE MID/UPPER RIO GRANDE VALLEY WITH MID/UPPER 40S CLOSER TO THE COAST. THESE LOW TEMPERATURES WILL BE MUCH COOLER THAN LOWS REACHED THE PAST COUPLE OF NIGHTS AND PEOPLE SHOULD PREPARE THEMSELVES FOR THE MUCH COOLER LOWS.
