313 AM EDT THU SEP 17 2015 CURRENT SYNOPTIC PATTERN SHOWS A LARGE UPPER RIDGE ANCHORED OVER TEXAS WITH A WEAK UPPER TROUGH TO ITS EAST AND STRETCHING FROM THE EASTERN GULF AND FLORIDA PENINSULA. A REFLECTION OF THIS UPPER TROUGH WAS NOTED AT THE SURFACE AND SPARKING SCATTERED SHOWERS ACROSS SOUTHEAST GEORGIA THIS MORNING. THE CLOUDS AND EASTERLY FLOW WILL WARRANT LEANING TOWARD THE COOLER SIDE OF GUIDANCE FOR HIGHS EACH DAY. MEDIUM RANGE MODELS CONTINUE TO SHOW MAINLY DRY AND SEASONAL WEATHER THROUGH THE END OF THE WEEK AND MOST OF THE WEEKEND AS THE REGION REMAINS UNDER THE EASTERN END OF A FLAT UPPER RIDGE.
HIGH PRESSURE WILL REMAIN OVER THE REGION THROUGH THE END OF THE WEEK. INFRARED SATELLITE IMAGERY SHOWS HIGH LEVEL CLOUDS ASSOCIATED WITH A LOW PRESSURE SYSTEM OVER THE DEEP SOUTH OVERSPREADING OUR AREA BUT ALSO HINTING THAT THESE CLOUDS WILL EVENTUALLY PUSH EAST AND THUS WE SHOULD SEE SOME CLEARING FROM WEST TO EAST AS THE MORNING PROGRESSES. HIGH PRESSURE STILL HANGING ON ACROSS THE MID ATLANTIC STATES WITH NO FLOW ALOFT WILL SET UP YET ANOTHER DRY DAY ACROSS THE FORECAST AREA. TEMPERATURES WILL ONCE AGAIN TOP OUT IN THE MID 80S WITH LOWS IN THE LOWER 60S.
THE BASE OF THE TROUGH AND CENTER OF UPPER DYNAMICS SWINGS THROUGH SE OREGON TO THE ID/NV BORDER THIS AFTERNOON. THE TROUGH QUICKLY MOVES EAST OF THE AREA TONIGHT WITH PRECIPITATION TAPERING OFF FROM WEST TO EAST IN THE EVENING.
RIDGING WILL RETURN LATER THIS WEEKEND. WHICH WILL PRODUCE WARMER AND DRIER CONDITIONS. THE NCEP RMOP IS IN CONFIDENT TERRITORY WITH THE PROGRESSION OF THE TROF ACROSS THE WEST THIS FORECAST PERIOD.
ONE FINAL DAY OF ACTIVE WEATHER THIS WEEK AS ONE MORE UPPER TROUGH SWINGS ACROSS THE PAC NW TODAY. THE LOWERING SNOW LEVELS ACCOMPANYING THE TROUGH WILL RESULT IN AN ADDITIONAL 1 TO 3 INCHES OF SNOW ABOVE 7500 FT TODAY. BOTH MODELS LIFT A DECAYING UPPER LOW ACROSS THE GREAT BASIN AROUND MID-WEEK. WHILE MINIMUM RELATIVE HUMIDITY IN THE LOWER VALLEYS SHOULD BE NEAR 40 PERCENT AND VALLEY HIGH TEMPERATURES MAINLY IN THE 50S.
1101 PM MDT WED SEP 16 2015 MAIN WEATHER PRODUCER FOR THE CWA OVER THE NEXT COUPLE DAYS WILL BE FROM AN UPPER TROF THAT IS CURRENTLY MOVING ONSHORE OVER THE PACIFIC NW WITH AN UPPER LOW OFF THE OREGON COAST. PCPN SHOULD INCREASE AND BE MORE WIDESPREAD THURSDAY NIGHT AS THE MAIN UPPER TROF MOVES EAST ACROSS THE REGION ALONG WITH A REINFORCING PUSH OF COOLER AIR WITH SHOWERS ENDING FRIDAY MORNING AS THE MAIN TROF AXIS MOVES INTO THE PLAINS. COOL FRIDAY NIGHT ESPECIALLY OVER THE WESTERN VALLEYS WHERE MINS MAY FALL INTO THE LOWER 30S IN FAVORED LOCALES.
COLD FRONTAL PASSAGE EARLY FRIDAY WILL LEAD TO A PLEASANT WEEKEND FOR MOST OF THE CWA.
FAIR AND WARMER OVER THE WEEKEND. UPPER LEVEL LOW OVER THE AREA MOVING TO THE EAST TODAY. HIGH LEVEL MOISTURE WILL BE SHIFTING EAST BY THIS AFTERNOON AS UPPER TROUGH AXIS SHIFTS TO THE COAST.

FOLLOWED BY COOLER TEMPERATURES AND BREEZY CONDITIONS ON THURSDAY. UPPER LEVEL LONGWAVE TROUGH. CLOSER TO THE COLD AIR ASSOCIATED WITH THE UPPER LEVEL TROUGH. BUT EXPECT INCREASING SUBSIDENCE THROUGH THE DAY WITH HIGH PRESSURE BUILDING OVER THE AREA.
EXPECT A LITTLE WARMER TEMPERATURES EACH DAY WITH A LITTLE MORE HUMIDITY. THE RIDGE WILL BEGIN TO BREAK DOWN ALLOWING A COLD FRONT TO SINK INTO THE AREA.
539 AM CDT THU SEP 17 2015 EXPANDING RIDGE OF HIGH PRESSURE WILL BRING MOSTLY VFR CONDITIONS THRU THE FCST PERIOD. /ISSUED 511 AM CDT THU SEP 17 2015/ THIS MORNING AN UPPER LEVEL RIDGE OF HIGH PRESSURE WAS CENTERED OVER WEST TEXAS NEAR THE BIG BEND AREA AND EXTENDED EAST AND NORTHEAST ACROSS THE FOUR STATE REGION AND INTO THE TENNESSEE VALLEY. OVER THE NEXT COUPLE OF DAYS THIS RIDGE WILL REMAIN OVER THE AREA WITH A GRADUAL WEAKENING AS A SERIES OF UPPER LEVEL SHORT WAVES MOVING AROUND A UPPER LEVEL TROUGH OF LOW PRESSURE ROUND THE NORTHERN PERIPHERY OF THE RIDGE ALOFT. BY LATE FRIDAY NIGHT A COLD FRONT ASSOCIATED WITH THE DEEPENING UPPER LEVEL TROUGH ACROSS THE CENTRAL AND SOUTHERN PLAINS WILL RETURN RAIN CHANCES FOR THE FAR NORTHWEST ZONES IN SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS.
HIGH PRESSURE REMAINS IN CONTROL FOR THE TAF PERIOD.
403 AM CDT THU SEP 17 2015 UPPER RIDGING OVER TX WILL CONTINUE TO EXERT ITS INFLUENCE OVER MIDDLE TN TODAY AND AGAIN ON FRIDAY. THE RIDGE AXIS SILL FINALLY SHIFT SOUTHEASTWARD BY THE WEEKEND. THE WESTERLIES WILL PICK UP AND A COLD FRONT WILL TRAVERSE THE REGION.
229 AM PDT THU SEP 17 2015 AS DRIER CONDITIONS RETURN TODAY, TEMPERATURES REMAIN COOLER THAN AVERAGE THROUGH FRIDAY MORNING BEFORE A WARMING TREND FOLLOWS INTO THE WEEKEND.
A TROUGH OF LOW PRESSURE WILL MOVE ACROSS THE NORTHERN ROCKIES AND GREAT BASIN THROUGH TONIGHT. HIGH PRESSURE WILL BUILD OVER THE GREAT BASIN THROUGH THE COURSE OF THE WEEKEND.
The seemingly permanent subtropical ridge will continue the hot temps (5-10 degrees above normal) thru Friday.
654 AM EDT THU SEP 17 2015 DRY HIGH PRESSURE WILL KEEP OUR WEATHER QUIET AND WARM INTO THE START OF THE WEEKEND.
257 AM CDT THU SEP 17 2015 High pressure aloft is in control of our weather regime, and will continue to keep a tenuous hold over the next 24 hours. Southerly winds will keep the low levels mixed enough to keep temperatures in the 60s and 70s. Humid conditions will result in heat index values in the low to mid 90s. A cold front will remain lurking off to our northwest, extending from northwestern Missouri into south central Kansas. As this low slides to the northeast with time, the cold front will finally get a good kick to the southeast and sweep through the area from mid evening through the overnight hours.
REGIONAL SATELLITE/WV IMAGERY SHOWERS UPPER-LEVEL TROUGH HAS DIVED FURTHER SOUTH INTO GULF OF MEXICO. AS THE LOW MOVES AWAY.
434 AM EDT THU SEP 17 2015 WARM AND DRY WEATHER WILL CONTINUE TODAY WITH HIGH PRESSURE TO OUR EAST.
128 AM EDT THU SEP 17 2015 HIGH PRESSURE WILL STAY PARKED OVER THE MID ATLANTIC STATES INTO THE UPCOMING WEEKEND.
EARLY THIS MORNING A TROUGH CONTINUED TO PROPAGATE EASTWARD ACROSS THE STATE. EAST OF THE TROUGH. WEST OF THE TROUGH. CEILINGS ARE EXPECTED TO LIFT AND SCATTER LATER TODAY AS HIGH PRESSURE MOVES IN.
409 AM CDT THU SEP 17 2015 ALOFT: THE LONGWAVE TROF WAS OVER THE WRN USA WITH THE RIDGE OVER THE E. THIS TROF WILL DAMPLIFY AND HEAD INTO THE NRN PLAINS THIS AFTERNOON. THE NEXT TROF WILL MOVE ONSHORE INTO OR/CA/NV TODAY BUT WILL MOVE MORE E. BECOMING STATIONARY ALONG I-70 AS LOW PRES ORGANIZES OVER WRN KS IN RESPONSE TO THE APPROACHING TROF. THEN A COLD FRONTAL PASSAGE 13Z-14Z.
AN UPPER LEVEL HIGH PRESSURE AREA CENTERED OVER THE BIG BEND WAS GENERATING A NORTHERLY FLOW OVER SE TEXAS. WITH THE STRONGER HIGH PRESSURE RIDGE OVERHEAD. ISOLATED SHOWERS WILL BE POSSIBLE MAINLY OVER THE SOUTHWESTERN COASTAL AREAS AS SHOWN ON THE HIGH RESOLUTION TEXAS TECH AND ARW.
1238 AM CDT THU SEP 17 2015 AN UPPER RIDGE OVER TEXAS WILL BUILD TOWARD ARKANSAS TONIGHT AND THURSDAY.
SKIES WILL BECOME PARTLY CLOUDY ACROSS OUR INLAND ZONES WITH COOLER TEMPS IN THE UPPER 60S/LOWER 70S INLAND TONIGHT WHILE CLOUDY SKIES AND WAVES OF PRECIP CONTINUE ALONG THE COAST WITH MILD LOWS IN THE MID 70S.
SATELLITE AND RADAR IMAGES CONTINUE TO INDICATE SHOWERS DEVELOPING ACROSS PORTIONS OF NORTHERN TAMAULIPAS AND THE WESTERN GULF OF MEXICO EARLY THIS MORNING AS THE WEAK INVERTED TROUGH ACROSS EASTERN MEXICO CONTINUES TO MOVE FURTHER INLAND. THE 500MB RIDGE ACROSS NORTHERN MEXICO AND TEXAS THIS MORNING WILL CONTINUE TO BRING DRIER AIR ALOFT ACROSS EAST TEXAS INTO THE RIO GRANDE VALLEY TODAY INTO TONIGHT.
High pressure stretching from the eastern seaboard to the Gulf coast will keep our weather quiet through the short term. We'll have plenty of sunshine again today with afternoon temperatures a degree or two warmer than yesterday. On Friday a cold front will approach from the northwest, reaching an Alpena-Sedalia-Lubbock line by evening. Not uncomfortable, but a little warmer and more humid than what we've seen the last few days.
118 AM EDT THU SEP 17 2015 DRY HIGH PRESSURE WILL KEEP OUR WEATHER QUIET AND WARM THE NEXT SEVERAL DAYS.
LARGE SCALE TROUGHING ACROSS MUCH OF THE WESTERN US HAS BROUGHT A DRY SOUTHWEST TO WEST FLOW THROUGHOUT THE REGION.
642 AM EDT THU SEP 17 2015 WARM AND DRY WEATHER WILL CONTINUE TODAY WITH HIGH PRESSURE TO OUR EAST.
ISOLATED CONVECTION SHOULD POPPING BY MID AFTN JUST NW OF THE CWA WITHIN AXIS OF STEEP 0- 3KM LAPSE RATE/INCREASING BNDRY LYR MOISTURE CONVG JUST AHEAD OF A COLD FRONT APPROACHING THE CWA. THE COLD FRONT IS PROGGED TO SLOW AND BECOME NEARLY STAGNANT GENERALLY OVER THE SRN CWA.
CONDITIONS WILL BE BREEZY AGAIN TODAY AHEAD OF A COLD FRONT WHICH WILL CAUSE A WIND SHIFT OVERNIGHT TONIGHT INTO FRIDAY. SOME SHOWERS WILL ACCOMPANY THIS FRONT AND EVEN PRODUCE LIGHT SNOW IN THE HIGH MOUNTAINS ABOVE 10000 FT. THE AXIS OF THE UPPER LEVEL TROUGH WHICH HAS BEEN PLAGUING EASTERN UTAH AND WESTERN COLORADO THE LAST FEW DAYS WILL HAVE MOVED OFF TO THE EAST ALONG WITH THIS FRONT. THE PASSAGE OF THIS FRONT EARLY ON FRIDAY WILL RESULT IN DRIER NORTHWESTERLY FLOW DURING THE DAY AS HIGH PRESSURE OVER THE SOUTHERN US SLOWLY CREEPS NORTHWARD ALLOWING TEMPERATURES TO RECOVER AS HEIGHTS RISE. TEMPERATURES ACROSS NE UTAH AND NW COLORADO WILL REMAIN ON THE COOLER SIDE FRIDAY. NORTHWEST COLORADO AND THE UPPER GUNNISON RIVER VALLEY STAND THE BEST CHANCE OF FREEZING TEMPS (CRAIG ASOS HAS ALREADY RECORDED FREEZING TEMPS THIS MONTH.
An upper level ridge is parked over Texas with another north of The Bahamas. This low is within an elongated trough that extends into the northeastern Gulf of Mexico. The low will remain well south of the region today, but will help maintain the flow of moisture into our southeastern zones where 40-60% PoPs are in place. Max temps will reach the mid 80s in the drier areas and the lower 80s further southeast.
335 AM CDT THU SEP 17 2015 The approaching cold front from the Plains will cause increasing southerly flow in the lower troposphere, raising moisture levels across the forecast area. South winds will become gusty today ahead of the cold front, with sustained speeds of 15-20 mph, and gusts into the mid to upper 20 mph range this afternoon. The front slows a bit tomorrow as it runs into mostly parallel flow out of the southwest, but starts to break down the ridge over the eastern half of the country.
/ISSUED 403 AM CDT THU SEP 17 2015/ UPPER RIDGING OVER TX WILL CONTINUE TO EXERT ITS INFLUENCE OVER MIDDLE TN TODAY AND AGAIN ON FRIDAY. THE RIDGE AXIS SILL FINALLY SHIFT SOUTHEASTWARD BY THE WEEKEND. THE WESTERLIES WILL PICK UP AND A COLD FRONT WILL TRAVERSE THE REGION.
314 AM EDT THU SEP 17 2015 HIGH PRESSURE REMAINS OVER THE REGION THROUGH FRIDAY.
418 AM CDT THU SEP 17 2015 INCREASINGLY HOT AND RAIN-FREE WEATHER CAN BE EXPECTED LATE THIS WEEK AS THE SUBTROPICAL RIDGE PERSISTS OVER THE ARKLAMISS. THE FORECAST FOR FOG ALONG/S OF THE HIGHWAY 84 CORRIDOR EARLY THIS MORNING STILL LOOKS REASONABLE GIVEN THE INCREASINGLY MOIST BOUNDARY LAYER IN THE EAST-SOUTHEAST FLOW. /EC/ DRY WEATHER WILL CONTINUE OVER THE ARKLAMISS WITH THE SUBTROPICAL RIDGE OVER THE CWA FOR THE WEEKEND. MODELS CONTINUE TO SHOW SOME GOOD THERMAL RIDGING FOR THE WEEKEND WITH 850 TEMPS APPROACHING 20C AND SOME 925 TEMPS PUSHING TO 28C.
A HIGH PRESSURE RIDGE TO THE NORTH OF THE FCST AREA WEAKENS SLIGHTLY THROUGH TONIGHT AND SHIFTS EAST. THIS WILL CONTINUE TO MAINTAIN THE LOW LEVEL EAST TO NORTHEAST WINDFLOW ACROSS THE REGION THROUGH TONIGHT AND CONTINUES TO BRING INCREASING ATLANTIC LOW LEVEL MOISTURE TO THE REGION. LOW PRESSURE TROF NOTED IN SATELLITE IMAGERY THIS MORNING ALONG AL/GA BORDER REGION ALLOWING DRIER MIDLEVEL AIR OVER THE AREA (AS SEEN IN WATER VAPOR IMAGERY). LOWS TONIGHT RANGING FROM THE MID 60S OVER FAR INLAND COUNTIES TO THE LOWER 70S AT THE COAST.
A SHORT WAVE CONTINUES TO SLOWLY MOVE AWAY FROM THE REGION OVER THE SE STATES WHILE AN UPPER RIDGE BUILDS OVER EAST TX AND LA FROM NORTHERN MEXICO. A SUBSIDENT AIR MASS HAS MOVED OVER THE REGION AS THE RIDGE NUDGES IN AND WILL LINGER IN PLACE THROUGH THE WEEKEND. AT THE SURFACE, A RIDGE OF HIGH PRESSURE IS CENTERED OVER THE MID ATLANTIC COAST WITH A MOIST SE FLOW OVER THE LOCAL AREA ON THE SOUTHWEST SIDE OF THE RIDGE. EVEN WITH THE UPPER RIDGE BUILDING IN JUST ENOUGH MOISTURE IS IN PLACE THAT ONE OR POSSIBLY TWO SHOWERS MAY DEVELOP LATE IN THE AFTERNOON ALONG THE I-49 CORRIDOR SOUTH OF KAEX. LESS OF A CHANCE IS EXPECTED FRIDAY ALONG WITH SLIGHTLY WARMER TEMPS AS THE RIDGE SETTLES IN.
249 AM MDT THU SEP 17 2015 THE WEATHER OVER THE NEXT 24-36 HOURS WILL BE DOMINATED BY BROAD UPPER-LEVEL TROUGHING ACROSS THE PAC NW. MORNING WATER VAPOR SAT IMAGERY SHOWED THE MAIN TROUGH AXIS STILL WELL UPSTREAM ALONG THE WASHINGTON/OREGON COASTLINE. GFS/NAM/ECMWF ALL REMAIN IN GOOD AGREEMENT WITH THE BEST PVA OCCURRING AFTER 00Z FRI AS THE MAIN TROUGH APPROACHES. H25 JET IS PROGGED TO STRENGTHEN TO AROUND 90-100 KTS BY LATE AFTN WITH A COLD FROPA YIELDING EXCELLENT LLVL UPSLOPE OVER THE HIGH PLAINS BY EVENING. GFS AND NAM BOTH NEARLY YIELD A CLOSED LOW. FRIDAY NIGHT WILL MOST LIKELY FEATURE SUB-FREEZING TEMPS IN SOME LOCALES WITH THE COLD AIR MASS IN PLACE.
/ISSUED 249 AM CDT THU SEP 17 2015/ Mid level ridge center was located over west TX. with the ridge axis extending northeast over OK. The low level thermal ridge over the southern high Plains will expand east across OK today. The broad western CONUS trough will eject in two distinct pieces.
618 AM EDT THU SEP 17 2015 HIGH PRESSURE REMAINS IN CONTROL THROUGH FRIDAY.
351 AM CDT THU SEP 17 2015 AN UPPER LEVEL HIGH WILL INTENSIFY OVER THE STATE TODAY WITH HOT AND DRY WEATHER PREVAILING. SOUTHERLY WINDS NEAR 15 MPH WILL CONTINUE AS A LARGE UPPER TROUGH APPROACHES THE PLAINS. AS THE TROUGH MOVES THROUGH THE PLAINS FRIDAY IT WILL SEND A COLD FRONT SOUTHWARD.
249 AM CDT THU SEP 17 2015 Mid level ridge center was located over west TX. with the ridge axis extending northeast over OK. The low level thermal ridge over the southern high Plains will expand east across OK today. The broad western CONUS trough will eject in two distinct pieces.
AN UPPER LEVEL LOW WILL MOVE ACROSS WESTERN WASHINGTON TONIGHT FOR MOSTLY CLOUDY SKIES AND SCATTERED SHOWERS. SKIES WILL CLEAR FROM THE NORTH BY AROUND MID-DAY SATURDAY AS THE LOW DEPARTS TO THE SOUTH.
UPPER LOW CONTINUES TO LINGER OVER THE REGION. WITH ANOTHER INVERTED TROUGH AXIS CROSSING THE CWA TODAY.
340 PM CDT FRI OCT 2 2015 (Tonight and Tomorrow) The forecast area will be under the influence of an upper ridge through tomorrow concomitant with dry weather, light winds and mostly clear skies. With a cooler and drier airmass in place. By Saturday night, an upper level closed low will be driving south along the California coast. This will result in lowering heights over our area in increasingly southwest flow as the upper level ridge edges east.
THIS THE RESULT OF THE UPPER LEVEL LOW CIRCULATION NOT MOVING MUCH UNTIL AT LEAST THE FIRST PART OF SUN AS IT SLOWLY DRIFTS SEWD. RIDGING INFLUENCES SFC/ALOFT WILL KEEP THE MID STATE DRY THRU MOST OF NEXT WORK WEEK. HIGHS WILL BE ONLY MAINLY IN THE LOW 60S ON SAT.
HAVE GUSTS 30 TO 35 MPH OVER THE MOUNTAIN RIDGES. STILL THINK THE LOW CLOUDS WILL HOLD SATURDAY WITH EASTERLY FLOW ALONG OUR EASTERN SLOPES.
CLOSED UPPER LOW IS NOW DIRECTLY OVERHEAD OF CENTRAL ALABAMA WITH THE DISTINCT SPIN NOTED ON IR SATELLITE IMAGERY. LOW LEVEL INVERTED TROUGH WILL REMAIN ACROSS EASTERN ALABAMA AND WESTERN GEORGIA WHICH WILL CONTINUE TO PROVIDE LIFT FOR NUMEROUS SHOWERS THROUGHOUT THE DAY. WE'VE ALREADY SEEN SOME EMBEDDED STORMS THIS MORNING DUE TO ENOUGH INSTABILITY ALOFT WITH THE COLD CORE UPPER LOW OVERHEAD.
315 PM CDT FRI OCT 2 2015 H500 BLOCKING PATTERN OVER THE EASTERN US WILL KEEP THE H500 TROUGH OVER THE WESTERN US MEANDERING INTO THE NORTHERN PLAINS TONIGHT AND SATURDAY. BUT THE BLOCKING FLOW TO THE EAST SHOULD KEEP THE MAIN CHANCE FOR SHOWERS ACROSS THE WEST AGAIN SATURDAY. NO FREEZING TEMPS IN THE NEAR TERM.
/issued 319 AM CDT FRI OCT 2 2015/ The upper ridge that has been in place across west Texas and southeast New Mexico the last several days will begin to move east later today and tonight as an upper level low /trough pushes east and weakens through the intermountain west. High temperatures will generally remain much above normal today near the departing ridge. The exception will be the extreme western Low Rolling Plains where surface ridging will feed cooler easterly low level flow into that area.
1257 PM CDT FRI OCT 2 2015 THE CENTER OF AN AREA OF HIGH PRESSURE WILL CONTINUE TO HOVER NEAR JAMES BAY AND WESTERN QUEBEC THROUGH SATURDAY. THE HIGH PRESSURE WILL KEEP PROVIDING THE NORTHLAND WITH COOL EASTERLY FLOW. THE HIGH PRESSURE WILL PROMOTE CLEAR SKIES AND LIGHT WINDS AT NIGHT. SATURDAY LOOKS JUST A TAD COOLER. THE FLOW FROM LAKE SUPERIOR WILL KEEP AREAS CLOSER TO THE LAKE WARMER IN THE UPPER 30S TO LOW 40S.
1241 PM CDT FRI OCT 2 2015 NORTH TEXAS WILL REMAIN IN BETWEEN A DEEP UPPER LOW OVER THE SOUTHEAST STATES AND A DEVELOPING TROUGH OVER THE WEST COAST. DESPITE RIDGING ALOFT.
659 PM EDT FRI OCT 2 2015 A STALLED FRONTAL BOUNDARY WILL REMAIN DRAPED ACROSS SOUTHERN NEW ENGLAND AS HIGH PRESSURE BUILDS BY TO THE NORTH TONIGHT THROUGH SATURDAY.
HIGHS IN THE LOW TO MID 80S AND MOSTLY SUNNY SKIES WILL MAKE TODAY A GREAT ONE TO GET OUTSIDE. 45 SEVERAL DAYS OF PLEASANT WX ON TAP WITH RIDGING. H5 RIDGE SHOULD BEGIN FLATTENING TOWARD MIDWEEK AS A WESTERN TROF BEGINS EDGING CLOSER TO TX. RAIN CHANCES INCREASE DURING THE SECOND HALF OF THE WEEK DUE TO THE COMBINATION OF THE MOISTURE RETURN AND APPROACH OF THE TROF.
The first of two low pressure systems will continue to lift up out of Utah into Wyoming tonight causing moisture to be wrapped back in western Montana. A secondary low pressure will dig southward along the Pacific coast. This low will pull polar air over the divide into western Montana and north central Idaho.
BUT WILL HAVE A HARD TIME PUSHING MUCH FARTHER EAST THAN HIGHWAY 281 DUE TO DRY AIR IN BOTH THE LOW AND MID LEVELS ACROSS EASTERN NEBRASKA. WITH HIGHS ONLY REACHING THE LOWER TO MID 50S. THE INFLUENCE OF THE UPPER TROUGH WILL DIMINISH SATURDAY NIGHT ALTHOUGH A DISTURBANCE IS FORECAST TO LIFT NORTHEAST WITHIN SWRLY FLOW ALOFT.
AN UPPER LEVEL TROUGH IS ACROSS THE SOUTHEAST WITH THE ASSOCIATED LOW OVER ALABAMA. THERE IS NOT ENOUGH CAPE TO SUPPORT WIDESPREAD THUNDERSTORMS ESPECIALLY WITH THE LOWER LEVELS A LITTLE CAPPED. HEAVY RAINFALL IS POSSIBLE WITH THE SHOWERS/THUNDERSTORMS TODAY AS SOUNDINGS IN THE LOW LEVELS ARE ALSO SATURATED WITH PWATS ~1. TEMPS WILL BE COOL IN THE LOW TO MID 60S.
THE UPPER LEVEL CLOSED LOW OVER THE SOUTHWEST U. SHORELINE AREAS WILL FEEL THE HIGHER WINDS AND GUSTS OVERNIGHT.
118 PM EDT FRI OCT 2 2015 A LARGE AREA OF HIGH PRESSURE ANCHORED OVER ONTARIO AND QUEBEC WILL CONTINUE TO PROVIDE SEASONABLY COOL TEMPERATURES AND A DRY NORTHERLY FLOW TO THE NORTH COUNTRY FOR TODAY AND THROUGH THE UPCOMING WEEKEND. CONTINUED DRY AND QUIET WITH SEASONABLY COOL/STABLE HIGH PRESSURE ANCHORED ACROSS WRN QUEBEC.
THIS WAS SOME WRAP AROUND MOISTURE COMING FROM LOW PRESSURE IN THE LOWER ATMOSPHERE WELL EAST OF THE CWA. MEANWHILE AN UPPER LEVEL LOW WAS NOTED OVER SOUTHERN AL INTO THE FLORIDA PANHANDLE.
BROAD LONG WAVE TROUGHING REMAINS IN PLACE OVER MUCH OF THE WESTERN UNITED STATES THIS AFTERNOON. THIS WILL BRING MUCH COOLER WEATHER TO OUR AREA TOMORROW ALONG WITH A CHANCE FOR SHOWERS. WITH SUCH A STRONG TROUGH AND DECENT COLD POOL MOVING OVERHEAD DURING THE HEAT OF THE DAY, THUNDERSTORMS WOULD NORMALLY BE EXPECTED. OVERALL, MOST OF US WILL NOT SEE ANY RAIN WITH THIS, BUT WE ALL WILL SEE BREEZY WINDS AND COOLER WEATHER WITH HIGH TEMPERATURES TOMORROW AROUND 10 DEGREES COOLER THAN TODAY.
UPPER LOW. WITH THE HIGHEST QPF TOTALS ACROSS THE NORTHEAST AND EAST CENTRAL PORTION OF THE FORECAST AREA. BUT THE COLD POOL ASSOCIATED WITH THE UPPER LOW WILL ALLOW FOR A FEW ELEVATED THUNDERSTORMS.
THIS ACTIVITY IS DUE TO AN APPROACHING UPPER TROUGH AND SPEED MAX ROTATING AROUND THE TROUGH LIFTING TO THE NE INTO THE PLAINS.
SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP IN THE VICINITY OF THE LOW. LIGHT SNOW HAS BEEN REPORTED IN THE HIGHEST ELEVATIONS. TEMPERATURES ARE MUCH COOLER BEHIND THE ASSOCIATED FRONT.
BROUGHT MAX TEMPERATURES MORE IN LINE WITH THE COOLER SUPERBLEND GUIDANCE, AS THICK CLOUD COVER IS MAKING IT DIFFICULT FOR TEMPERATURES TO REBOUND THIS MORNING. THE COMBINATION OF AN UPPER LEVEL TROF DIPPING OUT OF CANADA AND THE TROPICAL SYSTEM OFF THE COAST WILL CONTINUE TO SPIN MOISTURE BACK INTO NY AND PA ON SATURDAY.
THE CLOUDS AND PRECIPITATION WILL RESULT IN COOLER TEMPERATURES FOR CENTRAL/SOUTH CENTRAL KANSAS ON SATURDAY.
HIGH PRESSURE WILL CONTINUE TO MAINTAIN THE NORTH AND NORTHEASTERLY WINDS AROUND 10 KNOTS DURING THE DAY TIME AND 5-7 KNOTS OVERNIGHT FOR THE I-35 TERMINALS. SURFACE RIDGING MAINTAINS NELY WINDS OF 6 KTS OR LESS MOST AREAS. UPPER AIR ANALYSIS LAST EVENING SHOWED A TROUGH OVER THE EASTERN UNITED STATES AND A RIDGE FROM SOUTHERN NEW MEXICO TO MONTANA. A RIDGE EXTENDED DOWN THROUGH OKLAHOMA TO SOUTH TEXAS. DURING THIS PERIOD THE UPPER RIDGE WILL BUILD TO THE EAST OVER TEXAS. TEMPERATURES TODAY WILL BE AROUND FIVE DEGREES COOLER THAN YESTERDAY AND LOW TEMPERATURES SATURDAY WILL BE FIVE TO 10 DEGREES COOLER THAN FRIDAY.
UPPER LOW OVER THE SOUTHEAST STATES AND HURRICANE JOAQUIN NEAR THE BAHAMAS. I WOULD EXPECT THAT LOW TEMPS MAY BE A TOUCH WARMER /1-2 DEGF/ TONIGHT THAN THE PAST FEW NIGHTS GIVEN THE HIGHER CLOUDS. THE COLDEST TEMPS WERE GENERALLY IN THE LOW SPOTS/VALLEYS WHICH WERE PROTECTED MORE FROM THE WINDS.
A STRONG UPPER LEVEL LOW OVER AL WILL CONTINUE TO SPREAD CLOUDS ACROSS THE AREA THIS MORNING. A RATHER IMPRESSIVE AND SLOW MOVING UPPER LOW. LOW PRESSURE IN THE ATMOSPHERIC LOWER LEVELS. A LITTLE EAST OF THE UPPER LOW CENTER. WILL USE COOL NORTHEAST FLOW TO WRAP MOISTURE AND CLOUDS AROUND INTO THE LOWER MS VALLEY THROUGH THE SHORT TERM.
THIS AFTERNOON HIGH PRESSURE AT THE SURFACE EXTENDS FROM CANADA TO THE GULF COAST BEHIND A COLD FRONT THAT STRETCHES ALONG THE ATLANTIC EAST COAST TO THE YUCATAN PENINSULA. ALOFT A SHARP TROF AND UPPER LOW IS LOCATED ACROSS THE SE STATES AND THE EASTERN SECTIONS OF THE GULF WHILE A RIDGE IS NOTED FROM NORTH MEXICO ACROSS THE PLAINS.
