TROUGHINESS WILL CONTINUE OFF THE WEST COAST WHILE HIGH PRESSURE BUILDS IN OVER THE DESERT SOUTHWEST. PIECES OF ENERGY WILL CONTINUALLY ERODE THIS HIGH PRESSURE AND FORCE THE AXIS TO BE ORIENTED MORE NORTHEAST TO SOUTHWEST AS OPPOSED TO STRAIGHT NORTH AND SOUTH. A SHARP AND DEEP TROUGH WILL HAVE FORMED FROM THE GULF OF ALASKA ALL THE WAY DOWN TO THE SOUTHERN CALIFORNIA COAST. AS THE TROUGH COMES ASHORE LATE FRIDAY NIGHT. A SOMEWHAT STRONGER PIECE OF ENERGY WILL ROUND THE BASE OF THIS TROUGH AND CREATE A CLOSED LOW AND BREAK IT OFF.
1127 PM CST WED MAR 9 2016 AT H5 CLOSED UPPER LOW OVER MEXICO AS SEEN IN WATER VAPOR. TROUGH INTO THE NORTHERN PLAINS WITH STRONG RIDGE OVER THE EAST COAST AND RIDGE OVER THE WEST COAST. DESPITE MIN TEMPS NEAR FREEZING. LIMITING THE THREAT OF FREEZING PRECIP. UPPED AN ADDITIONAL DEGREE FARTHER WEST DUE TO DOWNSLOPE AND WARMER AT 850HPA.
352 AM CST THU MAR 10 2016 WARMER TEMPERATURES. WARM AIR ADVECTION/LEE SIDE TROUGHING/PRESSURE FALLS ARE CURRENTLY MAXIMIZED IN CENTRAL MONTANA. CONCUR WITH THIS IDEA AS THE MID/UPPER LEVEL RIDGE AXIS FLATTENS AS IT SHIFTS INTO THE WEST THIS AFTERNOON. OVERALL MUCH WARMER TODAY WITH HIGHS IN THE 60S MOST AREAS EXCEPT 50S IN THE TURTLE MOUNTAINS. A WEAK COLD FRONT WILL NUDGE INTO NORTHWEST NORTH DAKOTA BETWEEN 06Z-12 WITH SOME CLOUDS.
A RATHER STOUT 500MB RIDGE WITH HEIGHTS TO 5920 METERS WILL BUILD OVER AND OFFSHORE THE FLORIDA PENINSULA. EXCEPT REMAINING A FEW DEGREES COOLER ALONG THE BEACHES DUE TO SURF TEMPS IN THE MID 60S TO AROUND 70 DEGREES. LITTLE CHANGE INDICATED IN OVERNIGHT LOWS THAT WILL BE IN THE LOWER-MID 60S. DEEP LAYER RIDGE WILL CONTINUE TO DOMINATE THE WEATHER PATTERN ACROSS THE REGION.
ANOMALOUS LOW PRESSURE CONTINUES TO SPIN IN CENTRAL MEXICO WITH WARM MOIST AIR SPREADING NORTHWARD AHEAD OF IT. HIGH PRESSURE IS FOUND ACROSS THE UPPER MIDWEST. WITH A COLD FRONT NOW LARGELY THROUGH OUR AREA. WHICH WILL URGE THE COLD FRONT FARTHER EAST AND TAKE THE ASSOCIATED RAINFALL WITH IT. WHILE IT WILL BE WARMER THAN NORMAL AWAY FROM THE LAKE. ON FRIDAY THE CENTER OF HIGH PRESSURE SHIFTS EAST. WITH COOLER AT THE LAKE CONTINUES. THE FRONTAL ZONE THAT MOVED SOUTH OF THE AREA WILL LIFT BACK NORTH AS THE DEEP UPPER LOW GETS WRAPPED BACK NORTHWARD IN THE WSW UPPER LEVEL FLOW. DEPENDING ON HOW INTACT THE UPPER LOW IS WILL DETERMINE HOW WIDESPREAD THE SHOWER ACTIVITY IS AND HOW MUCH RAINFALL THERE WILL BE.
LOOK FOR WARM AND DRY WEATHER THROUGH FRIDAY UNDER WEAK HIGH PRESSURE ALOFT.
HIGH PRESSURE WILL CONTINUE TO BRING WARM AND DRY CONDITIONS TO THE REGION TODAY. MAINLY DRY AND COOLER CONDITIONS ARE EXPECTED OVER THE WEEKEND.
A MID/UPPER TROUGH REMAINS ANCHORED OVER MEXICO WHILE A LARGE SHIELD OF PRECIPITATION IS EXPECTED TO REMAIN SOUTH AND EAST OF OUR FORECAST AREA THROUGH TONIGHT AND THURSDAY. INCREASING CLOUDS WILL KEEP HIGHS FROM RISING OUT OF THE LOW 60S ACROSS SOUTHERN KS WHILE CENTRAL KS LOCATIONS SHOULD RISE INTO THE MID AND UPPER 60S ONCE AGAIN.
UPPER RIDGE WILL REBUILD ON THURSDAY AFTERNOON WITH SUNNY SKIES AND TEMPERATURES SIMILAR TO TODAY. WITH A CLOSED LOW OVER THE SOUTHERN PLAINS. HOWEVER BL WINDS INCREASE OVERNIGHT BOTH NIGHTS AND COULD HELP MIX OUT THE LOW LEVEL INVERSION.
WATER VAPOR IMAGERY SHOWS RIDGE BUILDING OVER THE NORTHERN ROCKIES WITH TROFFING OFF THE PAC COAST. WARM ADVECTION HIGH CLOUD IS SPILLING OVER THE RIDGE AND SPREADING OVER OUR WESTERN AREAS. BUILDING RIDGE HAS RESULTED IN A DEEPENING OF THE LEE SIDE TROF AND INCREASED GAP FLOW AT LIVINGSTON AND NYE. THEN AN INCREASE IN MTN TOP WINDS IS INDICATED BY THE MOST RECENT MODELS AS WEAK PACIFIC COLD FRONT APPROACHES. RIDGING AND BACKING OF THE UPPER LEVEL FLOW SHOULD BRING MOSTLY DRY CONDITIONS BY FRIDAY NIGHT. AND SHIFT TO COOLER EASTERLY SFC WINDS AND REDUCED MIXING. HIGHS IN OUR E/SE SHOULD BE A LITTLE WARMER TOMORROW THAN TODAY. WE ARE TALKING COOLER IN A RELATIVE SENSE ONLY. AS A COOLER AND WETTER TROUGH PATTERN MOVES INTO THE AREA DURING THE WEEK. KEEPING THE WEATHER UNSETTLED AND BRINGING IN COOLER CONDITIONS.
1157 PM EST WED MAR 9 2016 AVIATION A WEAK COLD FRONT WILL COMES THROUGH THE AREA EARLY TONIGHT. A LARGE HIGH PRESSURE SYSTEM MOVES IN CLEARING THE SKIES. THAT HIGH PRESSURE SYSTEM WILL BRING SUNSHINE FRIDAY WITH HIGHS IN THE 50S.
LATER IN THE PERIOD A BROAD WESTERN CONUS TROF FEATURING SEVERAL EMBEDDED WAVES WILL MOVE INTO THE CENTRAL CONUS.
HIGH PRESSURE WILL SLOWLY SHIFT EAST OF THE REGION THROUGH THE TAF PERIOD. THE HIGH OCCASIONAL HIGH LEVEL CLOUDINESS AND LIGHT WINDS. THE HIGH WILL BE WELL TO THE EAST AND A LARGE WEATHER SYSTEM WILL APPROACH.
314 AM CST THU MAR 10 2016 DEEP UPPER LOW OVER NORTHERN MEXICO IS RESPONSIBLE FOR THE IMPRESSIVE PLUME OF MOISTURE THAT IS SPREADING NORTHWARD ACROSS THE LOWER AND MID MS VALLEYS THIS MORNING. THIS FEATURE WILL WORK TO THE NORTH AS A WARM FRONT FRI NT.
MOST OF THE SHOWERS WILL STAY OVER THE NORTH AND FAR WEST CLOSE TO THE MAIN STREAM OF UPPER-LEVEL ENERGY RIDING NORTHEASTWARD OVER THE DECAYING RIDGE. WITH A FLATTENING RIDGE. FRONT FINALLY GETS ROLLING SOUTHWARD TONIGHT AS THE MAIN UPPER- LEVEL TROUGH DIGS INTO THE WESTERN GREAT LAKES. TEMPERATURES WILL BE COOLER AS A PERIOD OF COLD-AIR ADVECTION IS EXPECTED FRIDAY. POST-FRONTAL TEMPERATURES WILL BE ABOUT 10 TO 15 DEGREES COOLER THAN THE MID-WEEK WARMTH.
WV imagery indicates a closed off upper level low transitioning eastward across northern Mexico. Meanwhile, an upper level ridge of high pressure is moving east across the Intermountain West. Near the surface, an area of high pressure is shifting slowly east across the Upper Midwest. Associated "cold" front (trough) passage will bring a northerly wind shift Thursday morning. In fact, high pressure ridging building into the plains from the Desert SW will yield strong height rises and warmer temperatures Thursday. Slow-moving cutoff upper low spins nearly stationary near San Antonio, TX. Very dry air will surround this cyclone's circulation, and it will be difficult to overcome.
NUMEROUS SHOWERS AND THUNDERSTORMS WERE NOTED ACROSS THE LOWER MISSISSIPPI RIVER VALLEY INTO THE GOLF COAST WITH MOIST SOUTHERLY FLOW ACROSS THESE AREAS THANKS TO AN UPPER LOW PARKED ACROSS NORTHERN MEXICO. WITH SURFACE TEMPERATURES ABOVE FREEZING.
ONLY CHANGE WAS TO FOLLOW THE RAP13 HOURLY TEMPERATURES THE REST OF THE NIGHT WHICH REPRESENTS COOLER CONDITIONS. WINDS WILL BE ON THE LOW END OF CRITERIA. AN UPPER LEVEL RIDGE BEGINS NOSING INTO THE PLAINS.
LARGE HIGH PRESSURE RIDGE CENTERED JUST OFF THE CAROLINA/GEORGIA COAST CONTINUES TO DOMINATE THE WEATHER PATTERN BUT IT IS BEGINNING TO WEAKEN ITS HOLD ON THE SOUTHEASTERN U. THIS RIDGE SHOULD CONTINUE TO KEEP THE AREA PRECIPITATION FREE THROUGH THURSDAY. THIS RIDGE STILL TRIES TO KEEP A HOLD OVER GA FRI MORNING WHICH SHOULD KEEP THE INSTABILITY INDICES LOW SO ONLY GOING WITH SHOWERS FOR NOW AS IT ENTERS THE STATE THU NIGHT/FRIDAY MORNING.
THANKS TO A PASSING LOW PRESSURE SYSTEM AND COLD FRONT. HIGH PRESSURE WILL THEN BUILD IN FOR FRIDAY. THOUGH IT WILL BE COOLER FRIDAY.
MOST OF THE SHOWERS WILL STAY OVER THE NORTH AND FAR WEST CLOSE TO THE MAIN STREAM OF UPPER LEVEL ENERGY RIDING NORTHEASTWARD OVER THE DECAYING RIDGE. WITH A FLATTENING RIDGE. FRONT FINALLY GETS ROLLING SOUTHWARD TONIGHT AS THE MAIN UPPER LEVEL TROUGH DIGS INTO THE WESTERN GREAT LAKES. TEMPERATURES WILL BE COOLER. POST FRONTAL TEMPERATURES WILL BE ABOUT 10 TO 15 DEGREES COOLER THEN THE MIDWEEK WARMTH.
145 AM EST THU MAR 10 2016 HIGH PRESSURE TO OUR SOUTHEAST WILL PROVIDE WARM AIR AND KEEP TEMPERATURES UNSEASONABLY WARM TODAY. DRY AND SLIGHTLY COOLER CONDITIONS ARE IN STORE FOR THE FIRST PART OF THE WEEKEND.
1148 PM EST WED MAR 9 2016 PERSISTENT SOUTHWEST FLOW CONTINUES TO FEED ABUNDANT LOW LEVEL MOISTURE INTO THE FORECAST AREA LATE THIS EVENING AND EXPECT A WEAK COLD FRONT TO SAG SOUTH THROUGH THE AREA OVERNIGHT INTO THURSDAY MORNING. THIS PROCESS WILL BE SLOW AS A RIPPLE OF LOW PRESSURE TRACKS UP ALONG THIS FRONTAL BOUNDARY. SHOWERS WILL GRADUALLY FILL IN OVER TERMINAL OVERNIGHT AND PERSIST INTO MIDDAY THURSDAY AS CIGS FALL TO AT LEAST IFR AND PERHAPS LIFR AT TIMES BEFORE A WEAK COLD FRONT CLEARS THE AREA BY 18Z AND LEADS TO SLOWLY IMPROVING CONDITIONS. WITH 5+ SIGMA CUTOFF LOW OVER WESTERN MEXICO AND DOWNSTREAM RIDGING OVER THE EASTERN US. COPIOUS GULF MOISTURE FEEDING CONVECTION OVER THE LOWER MISSISSIPPI VALLEY STREAMING NORTHWARD. COLD FRONT EXTENDS SOUTHWESTWARD FROM PARENT LOW OVER CENTRAL QUEBEC.
346 AM EST THU MAR 10 2016 HIGH PRESSURE WILL EXTEND OVER THE AREA FROM OFFSHORE THROUGH THURSDAY NIGHT.
DOWNSLOPE FLOW WILL INCREASE THURSDAY AS A SHARP TROUGH MOVES ONTO THE WEST COAST AND SETS UP SOUTHWEST FLOW OVER THE FORECAST AREA.
However, this will do very little to change the present air mass across the high plains with H85 temperatures still ranging from around 10C across central Kansas to near 12C closer to the Colorado border. Expect lows back down into the 30s(F) and the lower 40s(F) Thursday night with still very little change to the general air mass. Slow-moving cutoff upper low spins nearly stationary near San Antonio, TX. Very dry air will surround this cyclone's circulation, and it will be difficult to overcome.
AN IMMENSE DEEP LAYER HIGH PRESSURE IS CENTERED EAST OF THE GEORGIA / FLORIDA COAST AND IS THE FEATURE CONTROLLING OUR WINDS AND WEATHER. THE LARGE AND ROBUST HIGH PRESSURE EAST OF THE GEORGIA / FLORIDA COAST WILL MAINTAIN FRESH WINDS ACROSS THE AREA THROUGH FRIDAY NIGHT. A TROUGH DIGGING ONTO THE NORTHWEST PACIFIC COAST WILL BEGIN TO NUDGE THE CUTOFF LOW OVER TEXAS OUT TO THE NORTHEAST FRIDAY NIGHT. THIS WILL RESULT IN A NUDGING OF THE RIDGE TO OUR NORTH FURTHER EASTWARD. WITH THE RIDGE IN CONTROL.
358 AM EST THU MAR 10 2016 HIGH PRESSURE WILL REMAIN OFF THE SOUTHEAST COAST THROUGH TONIGHT. LOW PRESSURE OVER THE NORTHEAST WILL PUSH A COLD FRONT SOUTH THROUGH THE REGION ON TONIGHT AND FRIDAY.
1246 AM EST THU MAR 10 2016 HIGH PRESSURE CENTERED OFF THE SOUTHEAST COAST WILL CIRCULATE A WARM SOUTHERLY FLOW INTO THE FORECAST AREA THROUGH FRIDAY. SOME HIGH CLOUDS EXPECTED RIDING UP THE WEST SIDE OF THE UPPER RIDGE. OVERNIGHT LOWS MAY ALSO OCCUR SHORTLY AFTER MIDNIGHT AND THEN BECOME MORE STEADY AS THE LOW LEVEL JET DEVELOPS AND CLOUDS INCREASE. THE UPPER RIDGE FLATTENS SOMEWHAT FRIDAY. ALLOWING WEAK MID-LEVEL DISTURBANCES TO MOVE OVER THE RIDGE AND ACROSS THE UPSTATE AND NORTHERN MIDLANDS FRIDAY AFTERNOON.
HOWEVER THE HIGH CLOUDS WILL LIKELY KEEP ANY CLOUDS THAT DO DEVELOP PATCHY. A TRANQUIL WEATHER PATTERN WILL PREVAIL ACROSS SOUTHERN CALIFORNIA THROUGH THURSDAY UNDER A RIDGE OF HIGH PRESSURE.
HIGH PRESSURE ALOFT IS OVER THE NORTHERN ROCKY MOUNTAIN REGION THIS AFTERNOON BUT THE NEXT WEATHER SYSTEM IS ALREADY MOVING INTO THE PACIFIC NORTHWEST.
330 AM EST THU MAR 10 2016 ALOFT - TROUGHING EXTENDED DOWN THE MID-CONUS TO A CLOSED LOW IN NORTH-CENTRAL AND NORTHEAST MEXICO. A 591 DM RIDGE STRETCHED FROM CUBA TO THE MID-ATLANTIC COASTAL WATERS. SURFACE - AN ACTIVE FRONT WAS STRUNG OUT FROM THE TX COASTAL PLAINS TO THE LOWER GREAT LAKES. HIGH PRESSURE NEAR 30 NORTH/70 WEST RIDGED WEST TO THE SOUTHEAST U. THE CLOSED LOW EASES UP INTO TX WITH THE FRONT SLIDING TO THE CENTRAL GULF COAST AS THE STACKED RIDGING TO OUR EAST SLIGHTLY WEAKENS WHILE IT SLIPS EASTWARD. THIS RIDGING WILL CONTINUE TO DOMINATE THE AREA WITH A DRY AND STABLE AIR MASS AND PREVAILING SOUTHEASTERLY LOW LEVEL FLOW.
COULD SEE FRONTAL BOUNDARY SWING BACK ONSHORE LATER AS THE LOW APPROACHES OUR WESTERN COASTAL WATERS.
Think we'll stay cooler today than the past couple of days with the clouds and light rain as well as notherly flow behind the cold front. Stuck fairly close to cooler members of guidance for highs which puts temperatures in the mid 50s to low 60s.
331 AM CST THU MAR 10 2016 UPPER TROUGH MOVING THROUGH THE CENTRAL PLAINS EARLY THIS MORNING HAD GENERATED A FEW SPRINKLES ACROSS CENTRAL NEBRASKA EARLIER IN THE NIGHT. IT SHOULD BE ANOTHER DAY OF ABOVE NORMAL TEMPS IN THE LOWER TO MID 60S. HIGH PRESSURE SHIFTS EAST FOR FRIDAY. THE CLOSED LOW THAT IS SPINNING ACROSS CENTRAL MEXICO BEGINS TO LIFT NORTHWARD THROUGH THE SOUTHERN PLAINS AND EVENTUALLY INTO THE MID MISSOURI VALLEY.
A COLD FRONT WILL DRIFT FROM WEST TO EAST TONIGHT BRINGING A TEMPORARY END TO THE WELL ABOVE NORMAL TEMPERATURES BUT ALSO HELPING FOCUS RAIN CHANCES BY THURSDAY ACROSS NORTHEASTERN INDIANA AND NORTHWESTERN OHIO. BEING ON THE COLD FRONT MOVING EAST ACROSS THE AREA. CLOSED LOW OVR OLD MEXICO WILL FINALLY OPEN AND NEWD IN WKNG FASHION LTR SUN AHD OF UPSTREAM KICKER DRIVING THROUGH THE SRN ROCKIES. VFR CONDITIONS SHOULD THEN PERSIST THROUGH THE EVE, WITH SOME POTENTIAL FOR RADIATIONAL COOLING FOG TO DEVELOP OVERNIGHT AS HIGH PRESSURE MOVES OVER THE AREA.
1252 AM EST THU MAR 10 2016 A COLD FRONT WILL BRING INCREASING CLOUDS TO THE AREA TONIGHT WITH SHOWERS DEVELOPING IN CENTRAL NEW YORK BY DAYBREAK THURSDAY. PERIODS OF RAIN CAN BE EXPECTED ACROSS ALL OF CENTRAL NEW YORK AND NORTHEAST PENNSYLVANIA THURSDAY INTO THURSDAY NIGHT, AS THE COLD FRONT SLOWLY DROPS SOUTH. FRIDAY WILL SEE A RETURN TO DRY AND COOLER WEATHER. A COLD FRONT WILL PRESS SLOWLY SOUTH ACROSS THE AREA LATER THURSDAY AND THURSDAY NIGHT. HIGH PRESSURE WILL BUILD BACK INTO THE AREA ON FRIDAY WITH PARTIAL CLEARING. TEMPERATURES WILL BE MUCH COOLER THAN THE PAST FEW DAYS BUT STILL ABOVE NORMAL.
HIGH PRESSURE WILL BUILD BACK INTO THE AREA TONIGHT THROUGH FRIDAY.
400 AM EST THU MAR 10 2016 STRONG UPPER RIDGE ALONG THE THE SE U. COAST GIVES WAY SLIGHTLY AS A STATIONARY COLD FRONT OVER THE MID U.
328 AM CST THU MAR 10 2016 (Today and tonight) An upper level low is currently located across central Mexico and is forecast to begin to move northeast today and tonight, eventually reaching south Texas by early Friday morning. As this upper level low moves northeast, better lift will begin to overspread West Central Texas from southeast to northwest today. Highs will generally be in the low to mid 60s.
18Z SFC DATA HAS A COLD FRONT RUNNING FROM NORTHERN LAKE HURON INTO NORTHERN TEXAS. AND HIGH PRESSURE BUILDS IN FROM THE PLAINS. DRY AND MILD CONDITIONS WILL BE SEEN ACROSS THE AREA ON THURSDAY WITH HIGH PRESSURE ACROSS THE MIDWEST. MAIN ISSUE WILL BE PRECIPITATION AMOUNTS THIS WEEKEND WITH SOUTH PLAINS UPPER LOW MOVING NORTH AND ASSOCIATED AREAS OF LIGHT TO MODERATE RAIN.
213 AM CST THU MAR 10 2016 Cutoff upper low was still sitting and spinning over northern Mexico this morning. which may end up being the highway 69 corridor. The cutoff upper low will begin the process of opening up and reengaging with the westerly flow to its north.
WEST TO SOUTHWEST WINDS ALOFT WILL STRENGTHEN THIS EVENING AS AN UPPER LEVEL LOW PRESSURE TROF APPROACHES THE ROCKIES. HIGH PRESSURE ALOFT IS OVER THE NORTHERN ROCKY MOUNTAIN REGION THIS AFTERNOON BUT THE NEXT WEATHER SYSTEM IS ALREADY MOVING INTO THE PACIFIC NORTHWEST.
A cold front has oozed southeast out of the CWA and into central MO. Slightly warmer 925mb temperatures and a bit more sunshine should allow temperatures to reach into the mid/upper 60s over the western CWA with lower 60s to the east.
206 AM CST THU MAR 10 2016 Cutoff upper low was still sitting and spinning over northern Mexico this morning. which may end up being the highway 69 corridor. The cutoff upper low will begin the process of opening up and reengaging with the westerly flow to its north.
349 AM EST THU MAR 10 2016 HIGH PRESSURE REMAINS CENTERED OFF THE SOUTHEAST COAST TODAY AS A COLD FRONT APPROACHES FROM THE WEST.
313 AM CST THU MAR 10 2016 The 08z surface analysis showed a cold front extending from Effingham to Paris. With cloud cover persistent for much of the day, and slightly colder air behind the cold front, highs today will be about 10 degrees cooler than yesterday. Winds will be southerly for a few hours this morning southeast of I-70, but the majority of the area will see northerly winds prevail between 10 to 15 mph as the cold front departs. The only real dry period will be tonight into Friday evening, as high pressure drifts eastward across the Great Lakes. Weekend rainfall chances will be traced to the disposition of the upper low currently spinning over central Mexico.
HIGH PRESSURE WILL RETURN FOR FRIDAY THROUGH THE WEEKEND.
THE REMARKABLY DEEP UPPER LOW OVER NORTHERN MEXICO WILL REMAIN THE PRIMARY INFLUENCE ON NORTH CENTRAL TEXAS'S WEATHER SITUATION THROUGH AT LEAST FRIDAY NIGHT.
HIGH PRESSURE OVER THE WESTERN ATLANTIC. AND LOW PRESSURE OVER SOUTH TEXAS.
A LARGE RIDGE OF HIGH PRESSURE OVER PORTIONS OF THE SERN US WILL KEEP A CDFNT FROM MOVING EAST OVERNIGHT AND THURSDAY.
Fog is also possible but will depend on the coverage of the low clouds. Therefore, will reduce rain chances for the rest of the night, leaving only a slight chance over the Big Bend and the Lower Trans Pecos. /issued 151 PM CST WED MAR 9 2016/ Strong upper level low pressure area centered in southwestern Mexico will slowly shift east into eastern Mexico through Thursday. This precipitation courtesy of mid level energy rotating northward around the upper low.
WITH A FLATTENING RIDGE. FRONT FINALLY GETS ROLLING SOUTHWARD TONIGHT AS THE MAIN UPPER- LEVEL TROUGH DIGS INTO THE WESTERN GREAT LAKES. TEMPERATURES WILL BE COOLER AS A PERIOD OF COLD-AIR ADVECTION IS EXPECTED FRIDAY. POST-FRONTAL TEMPERATURES WILL BE ABOUT 10 TO 15 DEGREES COOLER THAN THE MID-WEEK WARMTH.
MAX TEMPS FOR THE LOWER ELEVATIONS AROUND EL PASO COUNTY SHOULD BE IN THE U50S TO AOA 60F.
NORTHERLY SURFACE WINDS WILL LESSEN AND BECOME MORE VARIABLE OVERNIGHT AS THE RIDGE APPROACHES. LOWS TONIGHT WILL HINGE ON THE EXTENT OF THE CLOUD COVER BUT DID LOWER MIN TEMPS A FEW DEGREES IN THE NORTH AND THE NISH VALLEY WHERE CLEARING AND A CLOSER PROXIMITY TO THE RIDGE MAY RESULT IN COOLER TEMPS. UPPER LOW ACROSS MEXICO WILL CONTINUE TO REMAIN ADRIFT THROUGH THE END OF THE WORK WEEK AS THE MAIN POLAR JET HOLDS IN SOUTHERN CANADA. THE UPPER LOW ACROSS NORTHERN MEXICO WILL BEGIN TO LIFT NORTHEAST AS A STRONG KICKER SYSTEM COMES ON SHORE IN CALIFORNIA ON FRIDAY.
417 AM EST THU MAR 10 2016 A COLD FRONT ACROSS SOUTHEAST LOWER MICHIGAN AND NORTHWEST INDIANA WILL SINK SOUTHEAST ACROSS NORTHERN OH/NW PA TODAY.
1253 AM EST THU MAR 10 2016 HIGH PRESSURE TO OUR SOUTHEAST WILL PROVIDE WARM AIR AND KEEP TEMPERATURES VERY WARM INTO THURSDAY. DRY AND SLIGHTLY COOLER CONDITIONS ARE IN STORE FOR THE FIRST PART OF THE WEEKEND.
Temperatures are going to soar into the 80s and 90s today and Tuesday as strong high pressure resides over the Northern Rockies. The upper ridge will be centered over the Oregon/Idaho border therefore preventing the clouds from growing too much today. They will develop over the higher terrain of central Idaho including the southern Bitterroot and southern Sapphire Mountains.
EXPECT WARMER WEATHER ACROSS NORTHERN ARIZONA TODAY WITH INCREASING HIGH CLOUDS FROM THE SOUTH.
357 AM PDT MON JUN 8 2015 A RIDGE OF HIGH PRESSURE ALOFT WILL BRING WELL ABOVE NORMAL TEMPERATURES TO THE CENTRAL CA INTERIOR TODAY WITH ONLY A SLIGHT CHANCE OF AFTERNOON THUNDERSTORMS NEAR THE SIERRA CREST.
348 AM CDT MON JUN 8 2015 WEAK COLD FRONT IS CURRENTLY NEAR THE INTERSTATE 44 CORRIDOR WITH ISOLATED CONVECTION CONTINUING IN VICINITY. CONDITIONS CONTINUE TO TREND WARMER AND DRIER FOR MID TO LATE WEEK AS THE PRIMARY STORM TRACK REMAINS WELL NORTH OF THE REGION.
636 AM EDT MON JUN 8 2015 LOW PRESSURE OVER QUEBEC WILL GRADUALLY PUSH A WARM FRONT NORTH ACROSS THE AREA LATE TODAY AND TONIGHT. A TRAILING COLD FRONT WILL SLOWLY APPROACH FROM THE WEST TONIGHT AND TUESDAY.
327 AM CDT MON JUN 8 2015 UPPER LVL RIDGING OVER EAST TX. ALLOWING A BACKDOOR BOUNDARY TO APPROACH AREA AROUND BACKSIDE OF RIDGE. PERSISTENT WEAK MID LVL RIDGING MAY LIMIT CONVECTION THIS WEEK.
430 AM CDT MON JUN 8 2015 BASICALLY A TEMPERATURE FORECAST AS UPPER LEVEL RIDGING ENSURES A CLEAR TO MOSTLY CLEAR SKY AND A DRY FORECAST. THANKS TO A TROUGH AXIS SLIDING TOWARD THE EAST COAST AND A RIDGE AXIS EXTENDING NORTH THROUGH THE WRN CONUS. MODELS SHOWING HIGH PRESSURE IN PLACE OVER CO. WHILE LOW PRESSURE SLIDES EAST ACROSS CANADA ALONG WITH AN UPPER LEVEL DISTURBANCE. THOUGH SPEEDS WILL BE ON THE LOWER END /10 TO 15 MPH/ AS THAT BOUNDARY MOVES INTO THE FAR N/NW CWA BY LATE AFTERNOON. MODELS SHOWING 850MB TEMPS CLIMBING INTO THE LOWER/MID 20S DURING THE AFTERNOON. SOME MODELS/GUIDANCE SUGGEST IT COULD BE A BIT WARMER THAN THAT.
305 AM PDT MON JUN 8 2015 WARM CONDITIONS ARE EXPECTED TODAY AS HIGH PRESSURE BUILDS OVER THE AREA. LOW PRESSURE WILL APPROACH THE AREA AND ENTRAIN MOISTURE FROM THE REMNANTS OF TROPICAL STORM BLANCA.
THE UPPER RIDGE HELD CONVECTION DOWN TODAY. ALSO AS AN UPPER TROUGH IS DEEPENING INTO THE UPPER MID WEST.
ISOLATED THUNDERSTORMS MAY DEVELOP THIS AFTERNOON ALONG A WEAK COLD FRONT PASSING THROUGH THE REGION. /ISSUED 348 AM CDT MON JUN 8 2015/ WEAK COLD FRONT IS CURRENTLY NEAR THE INTERSTATE 44 CORRIDOR WITH ISOLATED CONVECTION CONTINUING IN VICINITY. CONDITIONS CONTINUE TO TREND WARMER AND DRIER FOR MID TO LATE WEEK AS THE PRIMARY STORM TRACK REMAINS WELL NORTH OF THE REGION.
1225 AM CDT Mon Jun 8 2015 The main threat in the short term will revolve around thunderstorms expected to develop this afternoon out ahead of a cold front across northern Missouri and northeastern Kansas. Couple that with a slow moving cold front dropping through the area, unidirectional shear paralleling the front and very wet antecedent conditions and, training storms producing heavy rain may be possible. The upper level trough will move through the region by tomorrow morning leaving the area in benign northwest flow aloft.
356 AM CDT MON JUN 8 2015 BASICALLY A TEMPERATURE FORECAST AS UPPER LEVEL RIDGING ENSURES A CLEAR TO MOSTLY CLEAR SKY AND A DRY FORECAST. THANKS TO A TROUGH AXIS SLIDING TOWARD THE EAST COAST AND A RIDGE AXIS EXTENDING NORTH THROUGH THE WRN CONUS. MODELS SHOWING HIGH PRESSURE IN PLACE OVER CO. WHILE LOW PRESSURE SLIDES EAST ACROSS CANADA ALONG WITH AN UPPER LEVEL DISTURBANCE. THOUGH SPEEDS WILL BE ON THE LOWER END /10 TO 15 MPH/ AS THAT BOUNDARY MOVES INTO THE FAR N/NW CWA BY LATE AFTERNOON. MODELS SHOWING 850MB TEMPS CLIMBING INTO THE LOWER/MID 20S DURING THE AFTERNOON. SOME MODELS/GUIDANCE SUGGEST IT COULD BE A BIT WARMER THAN THAT.
311 AM CDT Mon Jun 8 2015 Persistent upper ridge remains centered over Northern Mexico and extends up across NM and TX. Back to the west an upper low along the CA coast will spin in place for a couple of days before quickly swinging east. As the low moves east the upper ridge will slide underneath it and move back to the west. However it will keep moisture pushed up against the higher elevations. Did have storms over the higher elevations yesterday. Storm chances increase areawide late in the week as the upper low approaches.
CLOUDS WILL INCREASE LATER TODAY AS A COLD FRONT APPROACHES THE REGION FROM THE WEST.
VFR CONDITIONS EXPECTED FOR THE NEXT 24 HOURS AS HIGH PRESSURE CONTINUES ACROSS DEEP SOUTH TEXAS. THE LATEST WATER VAPOR IMAGERY AND 500 MB HEIGHTS SHOWS RIDGE PARKED OVER SOUTH CENTRAL TEXAS KEEPING A PERFECT SUMMER LIKE WEATHER THIS SUN AFTERNOON. THIS HIGH PRESSURE HAS ALSO CREATED A VERY RELAX PRESSURE GRADIENT ACROSS DEEP SOUTH TEXAS WITH A MODERATE SOUTHEAST FLOW. LIGHT WINDS RETURN AS THE GRADIENT WEAKENS WITH A SLIGHT INCREASE IN MOISTURE IN THE LOW TO MID LEVELS. 5 WITH GFS IN THE HIGHER SIDE. LOW TEMPERATURES WILL KEEP THE SAME TREND REMAINING IN THE LOW TO MID 70S.
359 AM EDT MON JUN 8 2015 AN ELONGATED MID TO UPPER LEVEL TROUGH CONTINUES TO PERSIST ACROSS WESTERN ATLANTIC EAST OF THE CAROLINAS COAST AND EXTENDS SOUTHWEST INTO THE EASTERN GULF. ALTHOUGH THE MID TO UPPER LEVEL TROUGH CONTINUES TO SHIFT EASTWARD OF THE REGION THE SURFACE AND LOW LEVEL FLOW BECOMES MORE SOUTHERLY WITH GUIDANCE INDICATING ADDITIONAL FLUX OF MOISTURE ACROSS THE FLORIDA STRAITS INTO SOUTH FLORIDA. FORECAST SOUNDINGS INDICATE SOUTHWESTERLY TO WESTERLY WINDS IN THE LOWER LEVELS TO UPPER LEVELS WHICH WILL LIKELY ALLOW AFTERNOON SHOWERS/THUNDERSTORMS TO AFFECT THE EAST COAST METRO AREAS.
146 AM EDT MON JUN 8 2015 HIGH PRESSURE WILL PREVAIL ACROSS THE REGION TONIGHT INTO MONDAY AHEAD OF A COLD FRONT THAT APPROACHES TUESDAY.
HIGH PRESSURE EXPECTED OVER THE GREAT BASIN THROUGH TUESDAY WITH MUCH WARMER AND DRY CONDITIONS PREVAILING.
