A MIX OF PCLDY/MCLDY CONDITIONS AS REGION LIES BETWEEN HIGH PRESSURE TO OUR NORTH AND EAST. AND A LEE-SIDE TROUGH BUILDING OFF THE ROCKIES/FRONT RANGE. EXPECTING TREND TO CONTINUE THRU TODAY AS TROUGH CONTINUES SLOW PUSH EASTWARD. FOCUS OF MOST RW/TRW POTENTIAL WILL BE OVER EASTERN ZONES OUT AHEAD OF TROUGH MOVEMENT. OVERNIGHT ON INTO THURSDAY MORNING DO EXPECT NO PRECIP AS TROUGH BREAKS DOWN.
OVERALL WEATHER PATTERN IS A PERSISTENT CLOSED UPPER LEVEL LOW PRESSURE SYSTEM SPINNING OFF THE OREGON COAST AND RIDGE OF HIGH PRESSURE OVER THE INLAND PACIFIC NORTHWEST. ON THURSDAY THE UPPER LEVEL LOW BEGINS TO MOVE TOWARDS THE COAST ALLOWING FOR A LITTLE MORE FORCING IN THE ATMOSPHERE LENDING ITSELF TO MORE CONVECTIVE ACTIVITY LATE IN THE DAY AND INTO THE OVERNIGHT PERIOD.
70/DD /ISSUED 319 AM CDT WED AUG 12 2015/ THE SURFACE COLD FRONT HAS MOVED WELL SOUTH OF THE AREA AND IS NOW LOCATED ALONG THE INTERSTATE 85 CORRIDOR. WITH TEMPERATURES EXPECTED TO BOTTOM OUT IN THE LOWER 60S ACROSS THE EAST. WITH HIGH PRESSURE SETTLING IN ACROSS THE REGION.
FAIRLY LIGHT MID LAYER FLOW THIS MORNING WILL INCREASE INTO LATE AFTERNOON FROM THE WNW/NW AT 500 MBS NEAR THE BASE OF L/W TROUGH ACROSS THE ERN STATES INTO N FL. HIGHS SHOULD REACH THE LOWER 90S ALL AREAS.
SCATTERED TO ISOLATED THUNDERSTORMS FORMING ON THE LOW LEVEL JET AXIS ACROSS WEST CENTRAL NORTH DAKOTA EARLY THIS MORNING. AS THE LOW LEVEL JET MIXES OUT DURING THE MORNING ENDED THE ISOLATED THUNDERSTORMS. THE MEAN H5 RIDGE AXIS CONTINUES OVER THE FORECAST AREA THROUGH THE SHORT TERM.
604 AM CDT WED AUG 12 2015 Dry conditions are expected to continue for the next several days as upper-level high pressure expands and builds across the southern High Plains and into the desert southwest. Monsoonal moisture lifting northward across the eastern Rockies will generally continue to fall well west of the forecast area as it rounds the ridge; far enough that even cold pool driven expansion of storms should not threaten the CWA through at least Thursday evening.
1220 PM EDT WED AUG 12 2015 AN UPPER TROF WILL KEEP PLEASANT CONDITIONS ACROSS PENNSYLVANIA TODAY AND THURSDAY. TEMPERATURES WILL REBOUND LATER THIS WEEK WITH HIGH PRESSURE BUILDING EAST FROM THE MID MISSISSIPPI VALLEY. SHOWERS MOVING AWAY FROM THE LAKE NOW AS THE TROUGH MOVES INLAND. SKIES MAY CLEAR OUT QUICKLY THIS EVENING AS WE ARE BEHIND THE TROUGH IN THE SUBSIDENCE. H5 TROF SLOWLY SHIFTS EASTWARD AND LIFTS INTO CENTRAL NEW ENGLAND BY 00Z FRI. WITH MAXES REACHING THE MID 70S NORTH AND THE LOWER 80S SOUTHEAST.
AND WILL LEAN TOWARD WARMER RAW MODEL GUIDANCE NUMBERS OVER MOS OR BIAS-CORRECTED GRIDS. WHICH MAY BE OVER-CORRECTING TO THE COOLER SIDE BASED ON RECENT LESS MIXY PATTERN. THIS SHOULD KEEP TEMPERATURES WARMER OVERNIGHT AND EXPECT LOWS IN THE MID-UPPER 60S MOST AREAS. AND DOWNSLOPE OF THE BUFFALO RIDGE IN SOUTHWEST MINNESOTA NOT FALLING BELOW 70.
HIGH PRESSURE ALOFT BUILDING INTO THE REGION FROM THE EAST WILL BRING HOT HIGH TEMPERATURES THIS WEEK WITH AN OVERALL DECREASE IN THUNDERSTORM ACTIVITY. THE EXCEPTION IS ACROSS THE EASTERN ZONES AS DRIER AIR PUSHES IN FROM THE EAST AS THE STRONG HIGH PRESSURE RIDGE THAT IS OVER TEXAS BUILDS WEST. MUCH LESS DAILY THUNDERSTORM ACTIVITY THURSDAY INTO THE WEEKEND AS STRONG HIGH PRESSURE TO THE EAST BUILDS OVER THE STATE.
730 AM EDT WED AUG 12 2015 UPPER LEVEL LOW PRESSURE WILL MAINTAIN SOME CLOUDS AND MINIMAL SHOWER CHANCES FOR PARTS OF THE REGION UNTIL HIGH PRESSURE BUILDS IN TONIGHT AND THURSDAY. LOW CONVECTIVE THRESHOLDS UNDER THE UPPER TROUGH.
SHORT TERM: (THROUGH LATE THIS AFTERNOON) HIGH PRESSURE WILL DOMINATE THE REGION TODAY WITH A MOSTLY SUNNY SKY AND PLEASANT CONDITIONS FOR AUGUST.
AN UPPER RIDGE AXIS EXTENDED OVER THE EASTERN ROCKIES AND HIGH PLAINS REGION WHILE A TROUGH OF LOW PRESSURE WAS DRIFTING OVER THE EASTERN GREAT LAKES REGION AND EAST COAST REGION. FLATTENING H850 RIDGE THEN FOCUSES THE H850 WARM PROD INTO NORTHWEST WISCONSIN LATE TONIGHT BEFORE SPREADING OVER NORTHERN WISCONSIN THURSDAY. ANOTHER WEAK TROUGH SLIDES OVER AT LEAST THE NORTH HALF OF THE STATE. THE UPPER NORTHWEST FLOW REMAINS TO PROVIDE SOME SHEAR BUT WITH THE WARMER LOWER LEVELS. PROGS SUGGESTS A COLD FRONT WITH SHORT WAVE WILL APPROACH FROM THE NORTHERN PLAINS BUT AFTER THE THURSDAY AFTERNOON PERIOD.
100 PM EDT WED AUG 12 2015 HIGH PRESSURE OVER THE CENTRAL PLAINS WILL MOVE ACROSS THE UPPER OHIO VALLEY/LOWER GREAT LAKES.
THE UPPER LEVEL HIGH WILL CONTINUE OVER THE SRN ROCKIES WITH WK MID LVL FLOW OVER NRN CO. ONCE AGAIN SHOULD SEE SCT TSTMS OVER THE HIGHER TERRAIN THIS AFTN. AS FOR HIGHS READINGS WILL BE WARMER THIS AFTN WITH TEMPS IN THE UPPER 80S TO LOWER 90S ACROSS NERN CO.
634 AM CDT WED AUG 12 2015 HIGH PRESSURE IS CENTERED OVER IOWA THIS MORNING AND WILL ONLY SHIFT SLIGHTLY EAST THROUGH THE DAY. DESPITE THE HIGH OVERHEAD. SOME MOISTURE HAS SLIPPED UNDER THE HIGH AROUND 5 KFT AND HAS RESULTED IN LOCALIZED AREAS OF FOG. LARGE UPPER LEVEL RIDGE REMAINING IN PLACE ACROSS THE WEST. WEAK BOUNDARY WILL BEGIN TO PUSH SOUTH THROUGH RIDGE INTO NORTHERN IOWA OVERNIGHT THURSDAY. LOW PRESSURE WILL COME ASHORE IN PAC NW BEGINNING TO BREAK DOWN RIDGE.
GRADUALLY IMPROVING CONDITIONS THROUGH THE PERIOD AS UPPER RIDGING MOVES INTO THE REGION. UPPER RIDGING SLOWLY TAKES EFFECT TODAY WITH GRADUAL CLEARING ALL BUT THE NORTHERN RIO GRANDE PLAINS. EXPECT VERY FALL LIKE TEMPERATURES TODAY WITH A COOLER AIRMASS.
TEMPERATURES WILL BE A BIT COOLER IN SOUTHEAST KS WHERE COLDER AIR WILL BE RECIRCULATED AND MIXING WILL BE LIMITED. MON-TUE: WITH LOW PRESSURE DEEPENING TO THE WEST. BUT COOLDOWN IS SHORT LIVED WITH DOWNSLOPE FLOW MODERATING THE COOLER AIR. TEMPERATURES BY SAT WILL BE AT LEAST IN THE LOWER 60S. AND WOULD NOT BE SURPRISED TO SEE LATER RUNS SHOW EVEN WARMER TEMPERATURES.

FOR 12Z TAFS LOW PRESSURE SYSTEM OVER THE GULF WILL PUSH NORTHWARD THE NEXT 24 HOURS. WITH COOLER TEMPERATURES IN OUR SOUTH. AND WARMER TEMPERATURES ACROSS THE NORTH DUE TO THE COPIOUS SUNSHINE. WILL FOLLOW THIS THINKING WITH SLIGHTLY WARMER TEMPERATURES FOR THOSE ALONG AND NORTH OF I-40. THE OTHER CONSEQUENCE WILL BE COOLER DAYTIME HIGHS ON MONDAY. RAINS SHOULD CLEAR OUT MONDAY NIGHT AND HIGH PRESSURE WILL REASSERT ITSELF ACROSS THE EASTERN HALF OF THE CONUS.
WILL WATCH THE HIGHS AS TEMPERATURES WILL PEAK OUT AROUND 60 SOUTHWEST AND THE 50S ELSEWHERE. WARM AIR ADVECTION WILL CONTINUE THROUGH THE DAY SUNDAY AS THE UPPER LEVEL RIDGE CENTERS OVER NORTH DAKOTA AND SURFACE RETURN FLOW INCREASES. TEMPERATURES IN THE LOW 60S ARE NOT OUT OF THE QUESTION WITH AMPLE SUNSHINE AND WEST/SOUTHWEST WINDS.
A COLD FRONT WILL SPREAD RAIN FROM NORTH TO SOUTH ACROSS THE REGION TODAY.
426 AM CST SUN NOV 8 2015 THERE IS AN UPPER LEVEL RIDGE ACROSS THE EASTERN 2/3RDS OF THE COUNTRY WHILE AN UPPER TROUGH WILL DIG SOUTH INTO CALIFORNIA. BUT FORECAST MODELS ARE IN GOOD AGREEMENT THAT THERE WILL BE NO PRECIPITATION ASSOCIATED WITH THIS KANSAS/MISSOURI UPPER LOW.

SKIES WILL BE MOSTLY CLOUDY WITH LOWS IN THE LOW 70S.
WIDESPREAD LIGHT TO MODERATE RAIN CONTINUES TO FALL ACROSS MUCH OF THE REGION EARLY THIS MORNING AS A COLD FRONT PUSHES INLAND. SNOW WILL LIKELY REMAIN RESTRICTED TO THE HIGHEST PEAKS TODAY AND WELL ABOVE AREA PASSES. OVERNIGHT TEMPERATURES WILL LIKELY REACH NEAR FREEZING ACROSS INTERIOR AREAS.
749 AM EST SUN NOV 8 2015 HIGH PRESSURE WILL BUILD OVER THE STATE THROUGH MONDAY BRINGING FAIR WEATHER.
WEAK LIFT ON THE NW SIDE OF THE LOW PRESSURE SYSTEM LOCATED ALONG THE LOUISIANA GULF COAST WILL ONCE AGAIN CAUSE OVERCAST MVFR CIGS AT THE I-35 SITES BEFORE RECOVERING TO OVERCAST VFR CIGS BY 15Z. WINDS WILL REMAIN OUT OF THE NORTH AT 10-15 KTS THIS MORNING BEFORE SUBSIDING TO 5-10 KTS THIS AFTERNOON AND EVENING AS THE LOW CONTINUES MOVING E-NE. THE LIFT ENDS BY MIDDAY AS WEAK MID LEVEL RIDGING TAKES HOLD. WELL BELOW (TODAY) TO BELOW (MONDAY) NORMAL TEMPERATURES ARE EXPECTED DUE TO COOL SURFACE RIDGING.
COLD FRONT HAS JUST ABOUT MADE IT THROUGH THE ENTIRE FORECAST AREA.
/ISSUED 435 AM EST SUN NOV 8 2015/ THE COLD FRONT HAS CLEARED THE CWA AND NOW A STRONG WEDGE IS BUILDING INTO THE CWA. MOST PLACES ACROSS NORTH GA WILL SEE TEMPERATURES INTO THE MID/UPPER 40S BY 00Z AND THE LOW/MID 50S ACROSS CENTRAL GA. THE STRONG WEDGE STAYS IN PLACE MONDAY WITH TEMPS NO GETTING MUCH WARMER ON MONDAY. THE STRENGTH OF THE WEDGE WILL BE ENHANCED AS LOW PRESSURE MOVES TO OUR SOUTH TODAY AND TONIGHT. A WEAK LOW PRESSURE SYSTEM IN THE NORTHEAST GULF OF MEXICO WILL MOVE NORTHEAST AS AN UPPER LEVEL TROUGH OVER GA TRANSITIONS TO THE EAST.
437 AM CST SUN NOV 8 2015 A DEVELOPING LOW PRESSURE SYSTEM CENTERED OVER THE NORTHERN GULF OF MEXICO WILL MOVE SLOWLY EAST AND INCREASE LOW LEVEL WARM ADVECTION/ISENTROPIC UPGLIDE OVER SOUTHEAST/EASTERN PORTIONS OF MS THIS AFTERNOON AND EVENING.
IN ADDITION A LOW LEVEL TROUGH AND ASSOCIATED AREA OF CONVECTION IN THE VICINITY OF PUERTO RICO AND THE HISPANIOLA CONTINUES TO TRACK TO THE NORTHWEST. THE FRONT IS EXPECTED TO MOVE INTO NORTH CENTRAL FLORIDA TODAY WHILE THE LOW IN THE GULF IS EXPECTED TO MOVE INTO THE NORTHEAST GULF. MEANWHILE THE LOW LEVEL TROUGH NEAR HISPANIOLA IS FORECAST TO TRACK NORTHWEST AND COULD BE IN THE VICINITY OF THE SOUTHEAST BAHAMAS THIS EVENING. PARTLY DUE TO THE SUBSIDENCE AHEAD OF THE TROUGH NEAR HISPANIOLA WITH THAT SUBSIDENCE CONTINUING AS IT TRACKS TO THE NORTHWEST. THIS SCENARIO WOULD CONTINUE TO FAVOR SUBSIDENCE AHEAD OF THE LOW AND AGAIN BRING SOME RELATIVELY DRIER AIR INTO SOUTH FLORIDA AND REGIONAL WATERS. THE COLD FRONT IS FORECAST TO START RETREATING NORTHWARD AS A WARM FRONT.
1004 AM EST SUN NOV 8 2015 A COLD FRONT WILL BECOME STATIONARY ALONG THE SOUTH CAROLINA COAST TODAY.
A WEAK UPPER LEVEL RIDGE WILL BRIEFLY BUILD OVER THE SOUTHERN PLAINS ON MONDAY AND RESULT IN SLIGHTLY WARMER TEMPERATURES WITH AFTERNOON HIGHS FROM THE MIDDLE 60S TO AROUND 70.
/ISSUED 312 AM CST SUN NOV 8 2015/ EXPANDED THE FROST ADVISORY SOUTH THIS MORNING AS TEMPERATURES ARE APPROACHING FREEZING IN WEST CENTRAL/SOUTHWEST OKLAHOMA PER MESONET DATA. AS AN ELONGATED MID-LEVEL TROUGH DEVELOPS A CLOSED CIRCULATION AND MOVES NORTHEAST. SURFACE WINDS WILL INCREASE ON MONDAY IN RESPONSE TO A LEE TROUGH AND A DEVELOPING WESTERN SYSTEM.
CLOUDY CONDITIONS ACROSS MUCH OF NORTHERN ALABAMA THIS MORNING WITH TEMPERATURES IN THE LOWER TO MID 50S IN MOST LOCATIONS. THIS CLOUD COVER IS BEING PRODUCED BY AN INVERTED TROUGH AXIS EXTENDING FROM AN AREA OF LOW PRESSURE SOUTH OF THE NEW ORLEANS AREA INTO NE ALABAMA AND WESTERN NORTH CAROLINA. FURTHER NORTH A STRONG AREA OF HIGH PRESSURE IS ANCHORED OVER THE OHIO VALLEY. THE INVERTED TROUGH OVER THE AREA WILL NOT MOVE MUCH. THIS SYNOPTIC COMBINATION WILL LIKELY STRENGTHEN CONVERGENCE AND ISENTROPIC LIFT ASSOCIATED WITH THIS INVERTED TROUGH AXIS. TIMING OF THE LOWER CIGS/APPROACHING MAY NEED TO BE ADJUSTED WITH FUTURE UPDATES.
-KT QUIET WEATHER IS EXPECTED IN THE SHORT TERM BENEATH UPPER RIDGING TO THE NORTH AND THE SLOWLY EASTWARD PROPAGATING SHEARED OUT REMAINS OF THE UPPER TROF TO THE SOUTH. WITH SOME PATCHY AREAS TRYING TO SPREAD NORTH INTO THE RATON RIDGE REGION AND EASTERN PORTIONS OF THE SAN LUIS VALLEY. SOUTH TO SOUTHWEST FLOW INTO THE SFC LEE TROF SHOULD HELP IT ERODE AS IT DOWNSLOPES OFF THE NRN SLOPES OF THE RATON RIDGE THROUGH THE MORNING. DRY AIRMASS OVER THE REGION TODAY SHOULD BODE FOR DRY AND WARMER TEMPERATURES. LEE TROUGHING INTENSIFIES AS SOUTHWEST FLOW ALOFT INCREASES OVER CO. AHEAD OF THE NEXT UPPER LOW DROPPING INTO THE PACIFIC NORTHWEST. THIS SHOULD KEEP TEMPERATURES MILD ALONG THE LOWER EASTERN SLOPES OF THE SE MTS. VALLEY TEMPERATURES WILL BE A MIXTURE OF TEENS IN THE COOLER TRAPPING VALLEYS.
/ISSUED 235 AM CST SUN NOV 8 2015/ THE ONCE POSITIVELY-TILTED UA TROUGH HAS SHEARED OFF INTO TWO PIECES. TEMPS FALLING TO/SLIGHTLY BELOW THE FREEZING MARK LATER THIS MORNING. THE AFOREMENTIONED LINGERING UA TROUGH IS PROGGED TO DEEPEN JUST A BIT AS IT COMMENCES TO SHIFT NE WITH TIME. AND SFC LEE TROUGHING WILL RESPOND IN KIND PROMOTING WINDS TO VEER TO THE S- SE AND BECOME SLIGHTLY BREEZY. LIGHT WINDS ARE ONCE AGAIN EXPECTED AND SFC RIDGING WILL ALSO BE IN PLACE. SO WILL EXPECT OVERNIGHT LOWS TO RANGE FROM THE LOW TO MID 30S ACROSS THE FAR SW TX PANHANDLE /MUCH LESS CLOUD COVER THERE/ TO THE LOW TO MID 40S ACROSS THE FAR ERN SOUTH PLAINS AND ROLLING PLAINS.
644 AM EST SUN NOV 8 2015 THE REGION WILL EXPERIENCE DRY AND COOL WEATHER AGAIN TODAY AS HIGH PRESSURE TRAVELS EAST ACROSS THE AREA.
Short range models indicate ridging aloft moving eastward across the Central Plains today while a strong upper level trough digs southeast into the Pacific Northwest. Warmer temperatures can be expected today as a strengthening lee side trough creates a strong southerly flow across western Kansas. Lows tonight can be expected back down into the 30s(F) in west central Kansas to the lower and mid 40s(F) in south central Kansas.
IN THE MID/UPPER LEVELS THE TROUGH WILL MOVE ACROSS THE EASTERN U. A WEAK LOW PRESSURE AREA WILL DEVELOP ALONG THE COOL FRONT STRETCHED ACROSS THE NORTHERN GULF AND NORTH FLORIDA TODAY AND THEN MOVE SLOWLY EAST NORTHEAST INTO THE FLORIDA PANHANDLE MONDAY. IT WILL REMAIN MUGGY WITH TEMPERATURES WELL ABOVE NORMAL AND ONLY EXPECTED TO FALL INTO THE LOWER TO MID 70S.
ONSHORE FLOW WILL INCREASE TODAY AS A LOW PRESSURE TROUGH APPROACHES FROM THE NORTHWEST. A COLD FRONT ASSOCIATED WITH THE FRONT WILL SWEEP ACROSS THE AREA ON MONDAY ACCOMPANIED BY A FEW LIGHT SHOWERS.

UPPER LEVEL TROUGH IS SLOWLY MOVING SOUTHEAST ALONG THE BRITISH COLUMBIA COAST TOWARD THE PACIFIC NORTHWEST. COLD FRONT IS CURRENTLY SITUATED ALONG THE OREGON AND WASHINGTON COAST. THIS COLD FRONT WILL SLOWLY TRACK EAST THROUGHOUT THE DAY AND REACH EASTERN OREGON AND SOUTHWEST IDAHO BY MONDAY MORNING. STRONG SOUTHWEST FLOW AHEAD OF THIS TROUGH WILL AID IN MIXING AND SURFACE WARMING TODAY. PRECIPITATION WILL SPREAD ACROSS THE REGION AHEAD OF THE COLD FRONT LATE SUNDAY NIGHT IN EASTERN OREGON AND MONDAY MORNING IN SOUTHWEST IDAHO.
325 AM PST SUN NOV 8 2015 A WEAK RIDGE OF HIGH PRESSURE WILL PROVIDE A CONTINUATION OF DRY WEATHER TO THE CENTRAL CALIFORNIA INTERIOR THROUGH TODAY.
922 AM CST SUN NOV 8 2015 Center of the high pressure extends from central Illinois east to Ohio this morning, with abundant clear skies in place. Winds starting to swing more southerly on the back side of the high, which is helping temperatures rise nicely from widespread lows in the 20s. High pressure, and the associated dry airmass, continues to dominate the local weather which should result in sunny skies.
A weak mid level upper low near El Paso may also help slightly with lift as it moves northeast and shears out over Oklahoma. Cooler air and decreasing winds behind the front will allow temperatures to fall into the lower 40s tonight over much of West Central Texas. Highs Sunday will be in the lower to mid 60s.
AS HIGH PRESSURE OVER THE UPPER OHIO VALLEY REGION WILL BE IN CONTROL. LARGE AREA OF STRONG HIGH PRESSURE CONTINUES TO BUILD INTO THE GREAT LAKES REGION EARLY THIS MORNING. WITH A BROAD UPPER LEVEL RIDGE AXIS ALSO BUILDING INTO THE UPPER MID WEST AND THE GREAT LAKES. TO THE LOWER 30S IN OUR SE CWA AWAY FROM ANY LAKE INFLUENCES. A LARGE AREA OF HIGH PRESSURE OVER THE EASTERN SEABOARD OF THE U. WILL CONTINUE TO RIDGE INTO NORTHERN MICHIGAN.
Temperatures were approaching the low and middle 30s, under clear skies and light breezes. This high pressure will bring ideal conditions for outdoor activities today. High pressure will be slow to move out of the Ozarks, keeping winds light and skies clear for tonight. This will once again drop temperatures well into the 30s, and even approaching the freezing mark for some locations.
Anticipated system and associated cold front beginning to move onshore early this morning. Showers will continue on Monday with the possibility of thunderstorms as upper low moves overhead.
940 AM EST SUN NOV 8 2015 THE REGION WILL EXPERIENCE DRY AND COOL WEATHER AGAIN TODAY AS HIGH PRESSURE TRAVELS EAST ACROSS THE AREA.
THE REMAINDER OF TODAY WILL BE BREEZY AND WARMER WITH DOWNSLOPE WARMING IN PLACE. WITH INCREASING HIGH CLOUDS STREAMING IN FROM THE WEST AS THE DEEP UPPER TROUGH MOVES ACROSS THE GREAT BASIN.
HIGH PRESSURE ACROSS THE REGION WILL KEEP CONDITIONS DRY AND COOL INTO THE START OF THE WEEK.
A LOW PRESSURE CENTER WITH A TRAILING COLD FRONT WEST OF THE WATERS WILL PROVIDE SOUTHEASTERLY WINDS TODAY AT SPEEDS OF 15 KNOTS OR LESS.
SOUTHWEST FLOW ALOFT TODAY BEGINS TO BACK TONIGHT AND MONDAY IN RESPONSE TO AN AREA OF LOW PRESSURE MOVING THROUGH THE PACIFIC NORTHWEST. ABOVE NORMAL TEMPERATURES TODAY WITH A WARMER START FOR MOST OF THE AREA AND SUNSHINE FOR A PLEASANT FALL DAY THOUGH MORNING HOURS WILL BE COOL WITH THE BREEZE. PACIFIC TROF CROSSING THE REGION TO START THE PERIOD CONTINUES TOO LOOK LESS IMPRESSIVE.
AND MONDAY VERY QUIET WEATHER FOR THE FIRST TWO DAYS OF THE WEEK WITH A WEAK UPPER RIDGE MOVING ACROSS THE REGION AND LITTLE IN THE WAY OF CLOUDS.
950 AM EST SUN NOV 8 2015 HIGH PRESSURE WILL BRING THE AREA MAINLY CLEAR SKIES AND SEASONABLE TEMPERATURES THROUGH MONDAY.
HIGH PRESSURE CENTERED OVER CENTRAL ILLINOIS HAS KEPT WINDS ON THE LIGHT SIDE. EXPECT MAX TEMPS TO BE A FEW DEGREES WARMER THAN YESTERDAY.
COOLER 40S IN THE I-30 CORRIDOR EXIST WHERE SKIES HAVE BEEN CLEAR LONGER. AIR TEMPS ARE IN THE LOW TO MID 50S. BEYOND THIS MID MONTH WE STILL HAVE SOME SEPARATION IN LONG RANGE MODELS WITH GFS BEING A TAD FASTER IN AN OPEN WAVE THAN THE EURO WHICH IS DEEPER AND SLOWER WITH A CLOSED LOW WHERE GFS HAS RIDGING. PRESSURE GRADIENT REMAINS RATHER TIGHT THIS MORNING ACROSS THE LOWER MISS VALLEY AND FOR THIS REASON.
High pressure, and the associated dry airmass, continues to dominate the local weather which should result in sunny skies.
WARM AIR ADVECTION WILL CONTINUE THROUGH THE DAY SUNDAY AS THE UPPER LEVEL RIDGE CENTERS OVER NORTH DAKOTA AND SURFACE RETURN FLOW INCREASES. TEMPERATURES IN THE LOW 60S ARE NOT OUT OF THE QUESTION WITH AMPLE SUNSHINE AND WEST/SOUTHWEST WINDS.
538 AM CST SUN NOV 8 2015 WEATHER WILL BE UNEVENTFUL TODAY WITH LITTLE MOISTURE OR FORCING AND UPPER LEVEL RIDGE IN PLACE. AN OVERALL QUIET LATE AUTUMN WEATHER PATTERN WITH ROUGHLY NEAR NORMAL TEMPERATURES WILL BE INTERRUPTED AND PUNCTUATED BY A SEASONALLY STRONG LOW PRESSURE CENTER MOVING ACROSS THE REGION AROUND MIDWEEK. PROGNOSTIC MODELS CONTINUE TO GRADUALLY CONVERGE ON SOLUTIONS FOR THE TRACK/TIMING OF THE LOW AND CONFIDENCE IS INCREASING IN A GENERAL EVOLUTION OF THE SYSTEM AND ITS SENSIBLE EFFECTS FOR OUR FORECAST AREA.
IT SHOULD BE INTO THE LOW 60S AT LEAST IN THE SOUTH AND MID/UPPER 50S ELSEWHERE. WOULD NOT BE SURPRISED TO SEE IT GET A BIT WARMER EVEN.
The area remains under strong influence of this ridge despite its slow exit, causing mostly clear skies and light winds. The result will be temperatures approaching the freezing mark, with temperatures in and around the metro area in the middle 30s. The mid level pattern remains somewhat disorganized with the exception of a weak closed low that will move through the area this evening.
A similar scenario will exist tonight, with the coldest valleys again dropping to near or just below freezing.
945 AM EST SUN NOV 8 2015 HIGH PRESSURE WILL BUILD OVER THE STATE TODAY.
PRESSURE GRADIENT REMAINS RATHER TIGHT THIS MORNING ACROSS THE LOWER MISS VALLEY AND FOR THIS REASON.

UPPER RIDGING SLOWLY TAKES EFFECT TODAY WITH GRADUAL CLEARING ALL BUT THE NORTHERN RIO GRANDE PLAINS. EXPECT VERY FALL LIKE TEMPERATURES TODAY WITH A COOLER AIRMASS.
By tonight srn extension of long wave will deepen, with closed low developing over OK/KS/MO border and as it does it will pick up plenty of glfmex moisture and bring a cool Monday rain.
WIDESPREAD RAIN WILL CONTINUE ACROSS SE GA THROUGH TONIGHT AS LOW PRESSURE APPROACHES FROM THE GULF.
848 AM EST SUN NOV 8 2015 IN THE WAKE OF A COLD FRONT. GUSTY WINDS WILL CONTINUE TO USHER A COOLER AND DRIER AIRMASS INTO THE REGION THROUGH TODAY.
600 AM EST SUN NOV 8 2015 LARGE AREA OF STRONG HIGH PRESSURE CONTINUES TO BUILD INTO THE GREAT LAKES REGION EARLY THIS MORNING. WITH A BROAD UPPER LEVEL RIDGE AXIS ALSO BUILDING INTO THE UPPER MID WEST AND THE GREAT LAKES. TO THE LOWER 30S IN OUR SE CWA AWAY FROM ANY LAKE INFLUENCES. A LARGE AREA OF HIGH PRESSURE OVER THE EASTERN SEABOARD OF THE U. WILL CONTINUE TO RIDGE INTO NORTHERN MICHIGAN.
High pressure will bring a sunny and cool day today to close out the weekend. There will be one mid/upper lvl trof and inverted sfc trof that may bring a bit of light rain to wrn KY/sw IN/se IL on Monday; amounts should stay less than 1/10 inch for the most part.
TODAY THROUGH MONDAY NIGHT THE UPPER PATTERN CONTINUES TO SHOW SPLIT FLOW ALOFT WITH A TROUGH OFF THE WEST COAST. RESULTING IN A BROAD UPPER RIDGE IN THE NORTHERN STREAM ACROSS THE NORTHERN PLAINS. WITH AN UPPER LOW OVER THE SOUTHERN PLAINS IN THE WEAKER SOUTHERN STREAM FLOW. SUBSIDENCE ASSOCIATED WITH THE UPPER RIDGE WILL LEAD TO SYNOPTIC SCALE DRYING AND WARMING. THE COMBINATION WILL LEAD TO PLEASANT FALL WEATHER TODAY AND AGAIN ON MONDAY WITH BREEZY WINDS CONTINUING OVER PARTS OF NERN WY AND THE HIGHER ELEVATIONS OF THE BLACK HILLS TONIGHT.
Showers have formed this morning in the Idaho panhandle ahead of an approaching trough of low pressure. Late tonight into Monday, the low pressure trough will begin to dig southward through eastern Washington and Oregon.
An upper level ridge will amplify within the northern branch of the upper jet across the northern plains while an intense upper trough digs onshore across the Pacific Northwest into central CA. A southern stream H5 trough over TX Sunday afternoon will amplify as it moves northeast into southeast KS and southwest MO late Sunday night. The stronger ascent ahead of the H5 trough will remain south and southeast of the CWA. Overnight lows will drop off into the lower to mid 30s across east central and northeast KS where the boundary layer may decouple enough for southerly winds to be light. Weak upper low still exits by Monday afternoon with south winds beginning to increase.
