THESE WERE WELL OUT AHEAD OF A COLD FRONT THAT WILL SWING THROUGH THE STATE LATER THIS MORNING.
335 AM PST TUE FEB 2 2016 UPDATED AVIATION SECTION HIGH PRESSURE WILL BRING DRY CONDITIONS AND MOSTLY CLEAR SKIES THROUGH THE WEEK.
THESE ARE MASKED BY THE HIGHER CLOUDS MOVING NORTHWARD FROM THE SYSTEM NOW OVER THE CENTRAL PLAINS. TEMPS HAVE GENERALLY BEEN WARMER THE PAST COUPLE OF DAYS BECAUSE THERE HAS BEEN MORE SUN THAN ANTICIPATED. THEREFORE WILL GO WITH THE HIGH RESOLUTION MODEL GUIDANCE WHICH DOES NOT SHOW ANY LIGHT SNOW IN OUR FAR SOUTHEAST UNTIL POSSIBLY 00Z WED.
IMPRESSIVE JET ROUNDING THE BASE OF THE TROUGH WITH THE INITIAL SHORT WAVE EMBEDDED IN THE CLOSED CIRCULATION. WITH MORE WARMER AIR SNEAKING INTO THE SOUTHERN PORTIONS OF OUR SERVICE AREA. BUT THERE IS A SECONDARY SHORT WAVE TROUGH THAT WILL ROTATE AROUND THE MAIN SYSTEM AND WILL PASS ACROSS THE AREA DURING THE EVENING AND OVERNIGHT HOURS.
A COASTAL TROUGH HAS TURNED POST-FRONTAL OVERNIGHT WINDS TO BE MORE NORTHERLY IN THE SAT/SSF AREAS. COLD FRONT WILL CONTINUE TO CLEAR THE FAR SOUTHEAST CWA EARLY THIS MORNING. COOLER TONIGHT AND WEDNESDAY WITH A DRY NORTHWESTERLY TO NORTHERLY FLOW.

MODERATE SOUTH WINDS AHEAD OF A PRE-FRONTAL TROF HAS KEPT THE VIS AT MVFR OR HIGHER CONDITIONS MOST OF THE NIGHT, HOWEVER WITH THE BOUNDARY MOVING TO NEAR A KLCH TO KAEX LINE WINDS HAVE STARTED TO DECREASE. LATER TODAY A COLD FRONT WILL MOVE THROUGH WITH WINDS BECOMING WEST THEN NW ALONG WITH CLEARING SKIES. AN APPARENT PREFRONTAL TROF. WELL AHEAD OF THE ACTUAL COLD FRONT WHICH IS STILL WEST OF THE HOUSTON AREA. MUCH COOLER AND DRIER AIR WILL SPILL INTO THE REGION TONIGHT BEHIND THE FRONT. CAA WILL CONTINUE WED AND INTO THU AS AN UPPER TROF AXIS TRANSLATES THROUGH THE CENTRAL AND ERN CONUS.
958 AM CST TUE FEB 2 2016 WATER VAPOR IMAGERY AND MOSAIC RADAR DATA INDICATE THE DRY SLOT ATTENDANT TO THE CNTRL PLAINS CYCLONE DEVELOPING NWD ALONG THE MO RIVER INTO E-CNTRL NEB AND W-CNTRL IA. WINDS SHOULD THEN RE-INTENSIFY BY EVENING ON THE BACKSIDE OF THE CYCLONE.
647 AM EST TUE FEB 2 2016 A WEAKENING COLD FRONT WILL MOVE NEAR OR INTO THE NORTHERN MIDLANDS EARLY THIS MORNING AND BECOME DIFFUSE.

TEMPERATURES WILL BE SLIGHTLY COOLER AS AIRMASS COOLS IN THE LOW LEVELS WHILE NORTHWEST WINDS INCREASE BY AFTERNOON AS LOW LEVELS BECOME WELL MIXED. CONTINUED GUSTY NORTHWEST WINDS TONIGHT BEHIND THE TROF WITH STRONGER SUBSIDENCE MOVING IN. TEMPERATURES IN THE POST FRONTAL AIRMASS WILL BE ABOUT 10 DEGREES COOLER THAN TODAYS READINGS. THOUGH THEY COULD BE COOLER AROUND THE METRO AREA IF THE WINDS ANTICYCLONIC WITH LIGHT SPEEDS OVER THE AREA. THE NAM SHOWS THE COOLER SOLUTION WITH HIGHS ONLY IN THE 40S WHEREAS OTHER SOLUTIONS KEEP THE AREA IN THE 50S.
THE MAIN FOCUS REMAINS ON PRECIPITATION CHANCES TONIGHT THROUGH TUESDAY NIGHT AS LOW PRESSURE MOVES UP THE OHIO VALLEY. SHARPENING MID LVL TROUGH W/200 METER HGTS FALLS ALG THE OH RVR PORTENT VIGOROUS SFC DVLPMNT LTR TUE AS THIS SYS LIFTS OUT THROUGH NEW ENGLAND WED. FUTHERMORE PER STG MID LVL TROUGH AMPLIFICATION. BELIEVE A STRONGER/FASTER DVLPG SFC CYCLONE SHLD RESULT WHICH WOULD SPRT A BAND OF HVY SNOW DVLPG TUE NIGHT.
A COLD FRONT HAS PUSHED INTO EXTREME NORTHWEST ALABAMA EARLY THIS MORNING. A RAPIDLY EVOLVING AND PROGRESSIVE SHORT WAVE TROF WILL DIG SOUTHWARD ON TUESDAY.
A WEAK COLD FRONT WILL EXIT THE STATE TO THE EAST MONDAY MORNING. HIGH PRESSURE RETURNS ON TUESDAY.
413 AM CST MON FEB 29 2016 A COLD FRONT IS RACING ACROSS THE CWA. AND THE LOW LEVEL BAROCLINIC ZONE. WITH THE LOWER RESOLUTION NAM/GFS AROUND 2 TO 3 INCHES. DRIER AIR IN THE LOW LEVELS WILL KEEP US FROM SEEING MUCH MORE THAN FLURRIES.
A COLD FRONT WAS LOCATED ROUGHLY ALONG A LINE FROM NEAR MINEOLA TX TO EL DORADO AR. THE FRONT WILL MAKE VERY LITTLE ADDITIONAL SOUTHWARD PROGRESS BEFORE MOVING BACK TO THE NORTH AS A WARM FRONT. CONVECTION IS EXPECTED TO DEVELOP ACROSS OKLAHOMA AND ARKANSAS TONIGHT BEFORE SPREADING SOUTHEAST ACROSS THE CWA ON TUESDAY AND BECOMING MORE WIDESPREAD AS THE TROUGH AND COLD FRONT MOVE INTO THE AREA. WIDESPREAD HEAVY RAIN IS NOT EXPECTED AS THE HIGHEST RAINFALL TOTALS ARE EXPECTED TO ONLY BE AROUND ONE INCH MAINLY ACROSS SOUTHEAST OKLAHOMA AND SOUTHWEST/SOUTHERN ARKANSAS. A TIGHT PRESSURE GRADIENT BEHIND THE COLD FRONT WILL RESULT IN GUSTY NORTHWEST WINDS TUESDAY AFTERNOON MAINLY WEST OF A LINE FROM TYLER TX TO DE QUEEN AR.

846 AM EST MON FEB 29 2016 SCATTERED SHOWERS WILL END THIS MORNING AS A COLD FRONT EXITS THE REGION. LOW PRESSURE WILL BRING WIDESPREAD RAIN TUESDAY NIGHT. SHOWERS ASSOCIATED WITH A COLD FRONT SHOULD EXIT THE RGN THIS MRNG. BRIEF RIDGING IS EXPD TO RESULT IN PARTIAL CLRG LATER THIS AFTN.
MIXING TO AROUND H85 WE SHOULD SEE DEW POINTS REMAIN IN THE LOWER 30S OR EVEN DROP INTO THE UPPER 20S.
Mostly clear skies across interior NorCal early this morning as we're now on the backside of a weak trough moving across the PacNW. Little change to the overall weather pattern through mid-week as a broad ridge remains in place that will continue to weaken and deflect incoming weather systems to our north.
Breezy conditions return by late Tuesday as weak low pressure moves across the Pacific Northwest.
406 AM CST MON FEB 29 2016 A WEAK COLD FRONT WILL STALL AND WASH OUT ACROSS SOUTHERN PORTIONS OF THE MID SOUTH TODAY. TEMPERATURES SHOULD AGAIN BE QUITE MILD WITH HIGHS RANGING FROM THE LOWER 60S NORTH. THIS SHOULD HAVE AN IMPACT ON THE QUALITY OF THE LOW LEVEL THERMODYNAMIC INSTABILITY.
402 AM CST MON FEB 29 2016 A DEVELOPING LEE TROF WILL ONCE AGAIN VEER WINDS TO THE SOUTHWEST BY THE LATE MORNING/EARLY AFTERNOON. A SHARP COLD FRONT CURRENTLY OVER CENTRAL SOUTH DAKOTA WILL BE PUSHING INTO THE NORTHERN TEXAS PANHANDLE SHORTLY AFTER MIDNIGHT AND WILL SURGE INTO THE SOUTH PLAINS REGION SHORTLY BEFORE 12Z TOMORROW MORNING.

These will likely be snow showers above 3000 ft elevations this morning given the cooler temperatures aloft.
Current readings across the region are in the upper 30s to the lower-mid 40s. With full sun, we'll still be battling cold air advection, so afternoon highs in the lower-mid 50s in the north with mid-upper 50s to around 60 across the south still looks on target. Despite the clearing of the clouds the CAA will fight some modest sunshine, and am planning 54-58 F under high pressure.
421 AM PST MON FEB 29 2016 HIGH PRESSURE ALOFT AND OFFSHORE FLOW WILL RESULT IN A WARMING TREND THROUGH TUESDAY. A COOLING TREND IS EXPECTED FOR THE SECOND HALF OF THE WEEK AS A WEAKENING COLD FRONT APPROACHES THE AREA AND BRINGS A SLIGHT CHANCE OF RAIN NORTH OF POINT CONCEPTION.
