519 PM CST MON FEB 9 2015 REINFORCING SHOT OF COOLER DRIER AIR HAS ARRIVED TODAY IN THE FORM OF A SECONDARY COLD FRONT. A STRONG PRESSURE GRADIENT IS CURRENTLY IN PLACE ACROSS THE LOWER MISS VALLEY RESULTING IN NNE WIND GUSTS PUSHING 20KTS ACROSS SOME TERMINAL SITES THIS AFTERNOON. SFC RIDGING QUICKLY SHIFTS EAST OF OUR REGION BY 00Z WED ALLOWING FOR SE WINDS RETURNING TO OUR NE TX TERMINALS DURING THE DAY TUESDAY WITH MOSTLY E TO NE WINDS ACROSS REMAINING TERMINALS. A WEAK COLD FRONT HAS MOVED ACROSS THE AREA TODAY BUT MOST OF THE COOLER AIR IS LAGGING WELL TO THE NORTH. TEMPS ARE EXPECTED TO BE SEVERAL DEGREES COOLER ON TUESDAY AS NELY LOW LVL FLOW FINALLY BRINGS SOME OF THIS COOLER AIR INTO THE REGION BUT AFTERNOON HIGHS WILL STILL BE WELL ABOVE NORMAL.
UPPER RIDGE BEGINS TO MOVE IN WITH VFR DEVELOPING. /ISSUED 332 PM CST MON FEB 9 2015/ TEMPERATURES HAVE STEADILY FALLEN THROUGHOUT THE DAY TODAY IN THE WAKE OF THE COLD FRONT THAT PASSED THROUGH THE MID-STATE EARLIER. SOUNDINGS INDICATE THE LOWER LEVELS ARE SATURATED UP TO 850MB MAINLY EAST OF INTERSTATE 65 THIS EVENING AND OVERNIGHT. SOUNDINGS INDICATE TEMPERATURES WILL GRADUALLY FALL BELOW FREEZING AFTER MIDNIGHT THROUGHOUT THE ENTIRE COLUMN. THUS AM THINKING A LIGHT DRIZZLE WITH A CHANGE OVER TO FREEZING DRIZZLE OR FLURRIES WILL BE POSSIBLE. SO NO MAJOR IMPACTS EXPECTED OTHER THAN SOME SLICK SPOTS ON BACKROADS AND BRIDGES ALONG THE CUMBERLAND PLATEAU.
253 PM PST MON FEB 9 2015 GUSTY WINDS AND SHOWERS WILL CONTINUE THROUGH THIS EVENING AS AN AREA OF LOW PRESSURE EXITS THE REGION, DISSIPATING OVERNIGHT. HIGH PRESSURE BUILDS INTO THE AREA FOR THE REMAINDER OF THE WEEK WITH MILD AND DRY CONDITIONS AND LIGHT WINDS RETURNING. UPPER LEVEL LOW CONTINUES TO LIFT TO THE NORTHEAST THIS AFTERNOON WITH ONLY LIGHT SHOWERS LINGERING MAINLY NORTH OF INTERSTATE 80. DRIER AIR MOVES INTO THE AREA AS THIS SYSTEM EXITS AND A RIDGE BUILDS BACK INTO THE WEST. OTHERWISE, DRY CONDITIONS ARE EXPECTED THIS WEEK WITH A GRADUAL WARMING TREND AS HIGH PRESSURE STRENGTHENS OVER THE WEST.
/ISSUED 203 PM CST Mon Feb 9 2015/ Above normal temperatures will prevail across southeast New Mexico and west Texas the next couple of days as an upper ridge translates eastward over the region.
617 PM EST MON FEB 9 2015 AVIATION MAINLY CLEAR AND COLD CONDITIONS ARE EXPECTED TONIGHT AS HIGH PRESSURE DRIFTS OVERHEAD.
658 PM EST MON FEB 9 2015 A COLD FRONT WILL CONTINUE PUSHING EAST TONIGHT BRINGING SHOWERS TO THE AREA.
BUT SCATTERED FLURRIES AND PATCHY FREEZING DRIZZLE WILL BE POSSIBLE OVERNIGHT.
WINDS COME BACK AROUND TO THE SE AND S (INCREASING TO 5 TO 10 KNOTS) DURING THE DAY TOMORROW AS HIGH PRESSURE MOVES OFF TO THE EAST. SINCE WE'LL START OUT A LITTLE COOLER IN THE MORNING (AND WITH WINDS GOING E/SE) DON'T ANTICIPATE QUITE AS WARM READING ON TUE BUT DID GO A TOUCH ABOVE GUIDANCE SUGGESTIONS.
549 PM CST MON FEB 9 2015 HIGH PRESSURE CONTINUES OVER THE AREA.
634 PM EST MON FEB 9 2015 COLD FRONT EXITS OVERNIGHT. HIGH PRESSURE TUESDAY NIGHT.
/ISSUED 341 PM CST MON FEB 9 2015/ DRY COLD FRONT MOVED THROUGH AND INTO THE GULF AS TEMPERATURES CLIMBED TO AROUND 80 DEGREES TODAY. RIDGING ALOFT WILL ALLOW FOR PLENTY OF SUNSHINE AS TEMPERATURES RECOVER INTO THE 60S TO NEAR 70.
As the surface cold front moves through, there is a brief window just ahead of the front where skies have cleared out and winds are light enough to allow for some fog development for a few hours, especially up towards the Tifton and Fitzgerald areas. However, this will be brief with gusty northwest winds developing behind the front, and this will usher in a cooler airmass with overnight lows ranging from near 40 across the northwest to the mid to upper 40s across the southeast big bend.
946 PM CST MON FEB 9 2015 HIGH PRESSURE SETTLING INTO THE LOWER MISSISSIPPI VALLEY WILL LEAD TO LIGHT NORTHEAST WINDS ACROSS THE REGION OVERNIGHT WHILE CLEAR SKIES ALLOW FOR GOOD RADIATIONAL COOLING. WINDS COME BACK AROUND TO THE SE AND S (INCREASING TO 5 TO 10 KNOTS) DURING THE DAY TOMORROW AS HIGH PRESSURE MOVES OFF TO THE EAST. SINCE WE'LL START OUT A LITTLE COOLER IN THE MORNING (AND WITH WINDS GOING E/SE) DON'T ANTICIPATE QUITE AS WARM READING ON TUE BUT DID GO A TOUCH ABOVE GUIDANCE SUGGESTIONS.
THE SATELLITE LOOP ALSO SHOWS THE ASSOCIATED COLD FRONT HAS BEEN LAYING OVER IN A MORE WEST-EAST ORIENTATION AS THE UPPER WAVE OUT-PACES IT ACROSS SOUTHERN WY. FOR THE MOST PART SHOWERS WILL MAINLY BE ON THE LIGHT SIDE AS THIS DISTURBANCE WORKS AGAINST THE MEAN RIDGE. ALSO A SECOND TROUGH WILL APPROACH ON TUE. COOLER TEMPERATURES ARE EXPECTED ON TUE.
1033 PM EST MON FEB 9 2015 HIGH PRESSURE FROM THE UPPER MIDWEST WILL MOVE TO NORTHWEST OHIO OVERNIGHT AND SLIDE EASTWARD ACROSS THE AREA TUESDAY INTO TUESDAY NIGHT.
MAYBE MIXED WITH LIGHT FREEZING RAIN OR SLEET SOUTH OF MADISON AND MILWAUKEE. THE HIGHEST AMOUNTS TOWARD THE NORTHERN FORECAST AREA.
911 PM EST MON FEB 9 2015 COLD FRONT EXITS OVERNIGHT. HIGH PRESSURE TUESDAY NIGHT.
Latest IR-satellite imagery pegs cloud tops at -9 to -11C over most of the area, so think as surface temperatures fall below freezing, we should see more flurries than freezing drizzle given ice nuclei likely to be present in the clouds. A 500mb trough will move east of Kentucky this afternoon. Temperatures tonight will fall into the mid 20s, with highs Tuesday rising into the upper 30s to the lower 40s.
THEN HIGH PRESSURE WILL BUILD OVERNIGHT WITH SOME PATCHY DENSE VALLEY FOG POSSIBLE BY TUESDAY MORNING. OTHERWISE WARM HIGH PRESSURE WILL BUILD WITH NEAR RECORD WARMTH POSSIBLE THROUGH MIDWEEK AS LIGHT OFFSHORE FLOW DEVELOPS. ANYWAY THE MAIN WEATHER STORY FOR THE NEXT FEW DAYS WILL BE THE POTENTIAL FOR SOME NEAR RECORD WARMTH AS STRONG HIGH PRESSURE BUILDS.
/ISSUED 253 PM PST MON FEB 9 2015/ GUSTY WINDS AND SHOWERS WILL CONTINUE THROUGH THIS EVENING AS AN AREA OF LOW PRESSURE EXITS THE REGION, DISSIPATING OVERNIGHT. HIGH PRESSURE BUILDS INTO THE AREA FOR THE REMAINDER OF THE WEEK WITH MILD AND DRY CONDITIONS AND LIGHT WINDS RETURNING. UPPER LEVEL LOW CONTINUES TO LIFT TO THE NORTHEAST THIS AFTERNOON WITH ONLY LIGHT SHOWERS LINGERING MAINLY NORTH OF INTERSTATE 80. DRIER AIR MOVES INTO THE AREA AS THIS SYSTEM EXITS AND A RIDGE BUILDS BACK INTO THE WEST. OTHERWISE, DRY CONDITIONS ARE EXPECTED THIS WEEK WITH A GRADUAL WARMING TREND AS HIGH PRESSURE STRENGTHENS OVER THE WEST.
1059 PM EST MON FEB 9 2015 SCATTERED FLURRIES OR EVEN SOME PATCHY FREEZING DRIZZLE IN SOME AREAS WILL LINGER OVERNIGHT.
THIS IS DUE TO AN UPPER LEVEL RIDGE MOVING OVER THE REGION. SCATTERED SHOWERS WILL CONTINUE THROUGH THE NIGHT OVER THE HIGHER TERRAIN OF BAKER COUNTY AND THE WEST CENTRAL AND BOISE MOUNTAINS WITH MVFR AND LOCAL IFR CONDITIONS ALONG WITH MOUNTAIN OBSCURATION.
/ISSUED 333 PM CST MON FEB 9 2015/ AT 3 PM SURFACE ANALYSIS DEPICTED A LOW PRESSURE CENTER OVER CENTRAL NORTH CAROLINA WITH A COLD FRONT TRAILING FROM THE LOW CENTER SOUTHWESTWARD ALONG THE GULF COAST. CLOUDS CONTINUE TO FILTER INTO THE REGION WITH NORTHERLY WINDS IN THE WAKE OF THE AFOREMENTIONED COLD FRONT EARLIER TODAY. COOL AND DRY CONDITIONS ARE THE HIGHLIGHT OF THE FORECAST PACKAGE THIS AFTERNOON WITH BELOW NORMAL TEMPERATURES RETURNING THIS WEEKEND. THE UPPER LEVEL TROUGH LOCATED OFF TO OUR EAST WILL CONTINUE ITS EASTWARD TRANSIT OVERNIGHT. AND THUS CLOUD COVER WILL DIMINISH ON TUESDAY AFTERNOON AS HIGH PRESSURE BUILDS IN AT THE SURFACE WITH RIDGING ALOFT. WINDS WILL PERSIST FROM THE NORTH ON TUESDAY KEEPING HIGHS COOLER THAN MONDAY.
307 PM MST MON FEB 9 2015 AN INCREASING SOUTHWEST TO WESTERLY FLOW ALOFT WILL BE OVER COLORADO AS A 110+ KT JET MAX RIDES OVER THE TOP OF THE RIDGE AS IT TRANSLATES ACROSS THE STATE. WL MENTION GUSTS TO 50 MPH IN THE MOUNTAINS ABOVE TIMBERLINE AND IN THE HIGHER FOOTHILL AREAS. EVENING TEMPERATURES ON THE PLAINS NOT ALL THAT COLD EVEN WITH THE PASSAGE OF A COLD FRONT EARLIER IN THE DAY. THE SAME HOLDS TRUE FOR THE HIGH COUNTRY WHERE BUT PCPN WILL BE ALL SNOW.
1040 PM EST MON FEB 9 2015 LATE EVENING SURFACE ANALYSIS DEPICTS A PAIR OF LOW PRESSURE CENTERS (1006 MILLIBARS) LOCATED OVER THE COASTAL CAROLINA REGION AND EXITING THE SOUTHEAST FLORIDA COAST. A COLD FRONT IS MOVING SOUTHEASTWARD AND EXTENDS FROM CENTRAL GEORGIA SOUTHWESTWARD TO THE FLORIDA PANHANDLE. LOW STRATUS AND AREAS OF GROUND FOG PREVAILED OVER MUCH OF OUR REGION AHEAD OF THE APPROACHING COLD FRONT. WE EXPECT LOW CLOUDS AND FOG TO SCOUR OUT FROM NORTHWEST TO SOUTHEAST AFTER MIDNIGHT AS LOW LEVEL WEST AND THEN NORTHWEST WINDS STRENGTHEN WITH THE APPROACH AND PASSAGE OF THE COLD FRONT. RANGING TO THE LOWER 50S IN COASTAL NORTHEAST FL. A COLD FRONT WILL CROSS THE COASTAL WATERS OVERNIGHT.
Drier and warmer conditions return Tuesday and will last through the remainder of the week. The final piece of energy is rotating across Norcal at press time with the upper low opening-up and moving across the Pac NW. The low tops were not conducive for large hail growth so heavy rain. and as the flow turns from cyclonic to anticyclonic in the wake of the vort max and upper low. High pressure rebuilds over the area for the rest of the week with dry and mild wx conditions.
