/ISSUED 149 PM CDT SUN AUG 2 2015/ Rain chances will continue the next few days as a somewhat weakened ua ridge remains over the region. The most favorable location for thunderstorms today/tonight will be over SE NM and the higher terrain of west Texas where the highest theta e currently resides. The low shear, but modest SBCAPE, environment will yield more storms capable of gusty winds to 50 mph, frequent lightning strikes and locally heavy rainfall through this evening, with storms dwindling overnight.
TODAY THROUGH TUESDAY NIGHT UPPER RIDGING CONTINUES ACROSS MUCH OF THE WRN CONUS INTO THE CNDN ROCKIES. CLOUDS WILL INCREASE FROM THE SW AS THE UPPER LOW APPROACHES. STRONG MOISTURE FEED WILL CONTINUE AHEAD OF THE LOW TUE WITH PWATS RISING TO 180 PERCENT OF NORMAL. BUT COULD END UP SLIGHTLY COOLER IF STORMS GET GOING EARLY IN THE AFTN.
325 AM EDT MON AUG 3 2015 UPPER AIR PATTERN CONSISTS OF A 500 MB RIDGE OVER THE ROCKIES AND A DEEP TROUGH OVER THE EASTERN HALF OF THE U. WITH SOME MOISTURE AROUND AND UPPER TROUGHING AS WELL. THE HIGHEST POPS WILL BE WITH THE HEATING OF THE DAY IN THE AFTERNOON AND EARLY EVENING. BASIC IDEA IS THAT WITH AN UPPER LOW MOVES NE OF THE CWA MON NIGHT INTO TUE. CIGS MAY DROP INTO THE HIGH END OF MVFR AT KCMX AND POSSIBLY AT KSAW TODAY. EXPECT WNW WINDS UP TO 20 KTS INTO MID WEEK AROUND DEEP LOW PRESSURE NEAR HUDSON BAY. THE ARRIVAL OF A HIGH PRESSURE RIDGE LATER IN THE WEEK WILL RESULT IN LIGHT WINDS UNDER 15 KTS.
MID-LVL TROUGH AXIS WILL REMAIN OVER THE GREAT LAKES REGION. AS COOLER AIR ALOFT BEGINS TO FILTER SOUTH ACROSS THE FORECAST AREA. MOST LOCATIONS SHOULD HAVE AFTN TEMPS WARM INTO THE UPPER 70S TO THE LOW 80S. WEAK LOBE OF VORTICITY PIVOTS AROUND THE TROUGH LATE TONIGHT. AND LIKELY REMAIN IN THE LOW 60S CLOSER TO THE LAKE. 500MB TROUGH AXIS BEGINS TO RELAX TO THE NORTH. HIGHS WILL APPROACH 80 TO THE LOW 80S. COOLER AND DRIER CONDITIONS STILL APPEAR LIKELY FOR THE BEGINNING OF THIS UPCOMING WEEK AS LARGE UPPER LEVEL LOW SETTLES INTO SOUTHERN CANADA AND THE NORTHEAST CONUS. WITH TEMPS IN THE LOW 80S LIKELY BOTH DAYS.
THE COMBINATION OF NW FLOW ALOFT (ALBEIT WEAK) AND WEAK MID LEVEL TROUGH (SEEN IN 5H HEIGHT/VORTICITY) CO-LOCATED WITH SAID MOIST AXIS FAVORS CONVECTION DEVELOPING WITHIN AND INVOF OF SAID FEATURES, POSSIBLY AS EARLY AS 18Z. BY WED HIGH TEMPS RAPIDLY RETURN TO UNCOMFORTABLY HOT CATEGORY AND WILL EASILY PERSIST THRU THE REMAINDER OF THE WEEK WITH 7H TEMPS OF 15-17C (+1 TO +3 STANDARD DEVIATIONS) UNDERNEATH SUPPRESSING PRESENCE OF THE SUBTROPICAL RIDGE.
A COLD FRONT WILL AFFECT THE AREA THIS WEEKEND. MAIN STORY FOR THE WED AND THU WILL BE THE HEAT AS TYPICAL SUMMERTIME PATTERN RE-DEVELOPS WITH HIGH PRESSURE OFFSHORE AND STRENGTHENING TROUGH INLAND. POPS WILL BEGIN TO INCREASE INLAND LATE THU AS MOISTURE INCREASES AHEAD APPROACHING SHORT WAVE AND SFC COLD FRONT. UPPER TROUGH DEVELOPS TO THE WEST WITH A WEAK COLD FRONT APPROACHING FROM THE NW. WITH AN AREA OF LOW PRESSURE MOVING ALONG IT.
406 AM EDT MON AUG 3 2015 A COLD FRONT WILL APPROACH THE REGION FROM THE WEST TODAY.
AS UPR TROF AMPLIFIES INTO THE UPR LKS. WITH THIS THERMAL TROF. CYC H85 NW FLOW IS PROGGED TO PERSIST AND MAINTAIN THERMAL TROF OVER THE CWA. BASIC IDEA IS THAT WITH AN UPPER LOW MOVES NE OF THE CWA MON NIGHT INTO TUE. CIGS MAY DROP INTO THE HIGH END OF MVFR AT KCMX AND POSSIBLY AT KSAW TODAY. THE ARRIVAL OF A HI PRES RIDGE LATER IN THE WEEK WILL RESULT IN LIGHT WINDS UNDER 15 KTS.
IT IS THIS FRONT WHICH PUSHED THRU LATE YDA RESULTING IN THE MUCH COOLER/DRIER AIR EXPERIENCED THIS MRNG WITH CLR SKIES. THIS COOLER/DRIER HIGH PRES AIRMASS WILL REMAIN OVER THE AREA THRU TNGT. THE UPR LOW WILL BEGIN TO MOVE FURTHER E TNGT WHILE RIDGING OUT WEST EXPANDS SLIGHTLY EWD. TEMPERATURES WILL RUN NOTICEABLY COOLER AND HUMIDITY LEVELS WILL BE MUCH LOWER. WITH THE UPPER LOW STILL PARKED OVER HUDSON BAY. HIGH TEMPERATURES APPROACHING 80 WITH DEW POINTS IN THE LOW 50S WILL FEEL VERY COMFORTABLE FOR MOST. COINCIDING WITH CYCLONIC CIRCULATION ON THE BACK SIDE OF THE LONG WAVE TROUGH.
BERMUDA RIDGE BUILDING INTO THE GULF OF MEXICO TUESDAY WILL SOLIDIFY INCREASING MOISTURE TREND. A WEAK UPPER LEVEL TROUGH WILL TRACK EASTWARD ACROSS THE MID MISSISSIPPI VALLEY WHICH WILL ERODE THE EASTERN SIDE OF AN UPPER RIDGE OVER THE LOCAL AREA. UPPER LEVEL RIDGE WILL MOVE TOWARDS NORTHERN TEXAS AND OKLAHOMA. RIDGE WILL REBUILD OVER EAST GULF WHILE A TROUGH DEVELOPS OVER THE PLAINS.
A LOW PRESSURE SYSTEM WILL SLOWLY THROUGH NORTHERN UTAH TODAY.
QUIET CONDITIONS ARE EXPECTED ONCE AGAIN TONIGHT AS A RIDGE OF HIGH PRESSURE GRADUALLY SHIFTS EAST. HIGH PRESSURE ALOFT WILL KEEP NORTH CENTRAL AND SOUTHWEST MONTANA MOSTLY CLEAR OVERNIGHT AND INTO THE DAY ON MONDAY, BUT THIN LAYERS OF SMOKE ALOFT FROM WILDFIRES ACROSS THE PACIFIC NORTHWEST WILL REMAIN OVER MUCH OF THE AREA. HOWEVER, A PACIFIC COLD FRONT ASSOCIATED WITH THE DISTURBANCE WILL MOVE THROUGH THE AREA LATE MONDAY NIGHT AND THROUGH THE DAY ON TUESDAY, WHICH WILL COOL TEMPERATURES TO BETWEEN 5 AND 10 DEGREES BELOW NORMAL FOR TUESDAY.
THIS SUBSTANTIALLY DEEPER MOISTURE IS PROG TO GRADUALLY SHIFT NORTH TONIGHT AND MONDAY MORNING AS A WEAK MID LEVEL TROUGH SHIFTS WEST.
UPPER LEVEL RIDGE REMAINS ACROSS SOUTHWEST CONUS WITH NORTHWEST FLOW ACROSS THE HIGH PLAINS. TOMORROW COOLER CONDITIONS WITH HIGHS IN THE 80S TO LOWER 90S. UPPER PATTERN INFLUENCED BY UPPER LOW OVER HUDSON BAY WITH AN UPPER JET AND ASSOCIATED PV ANOMALIES MOVING ACROSS THE UPPER MIDWEST AND GREAT LAKES AREA. AS THE JET ROUNDS THE BASE OF THE UPPER LOW. MEANWHILE SIGNIFICANT LEAD PV ANOMALY ASSOCIATED WITH AN UPPER TROUGH OFF THE CA COAST WILL MOVE ACROSS THE CENTRAL ROCKIES CONTINUING ITS NEG TILT. THIS LEAD PV ANOMALY WILL ENTER THE HIGH PLAINS MONDAY INTO TUES THOUGH THE MODELS DIFF SIGNIFICANTLY ON TIMING AND EVENTUAL LOCATION.
WITH READINGS IN THE LOWER 50S TO AROUND 60F. FOWLE A RIDGE OF HIGH PRESSURE AT THE SURFACE IS BUILDING SOUTHWARD ACROSS THE CWA. THIS HIGH WILL CONTINUE TO BRING THESE CONDITIONS LARGELY INTO MONDAY NIGHT EVEN. BUT WILL ALSO BEGIN WATCHING AN AREA OF LOW PRESSURE FORMING OVER THE HIGH PLAINS. A FEW MODELS ARE SHOWING AN ACTUAL CLOSED LOW AT THE SFC MOVING THROUGH WHILE OTHERS FEATURE MORE OF A BROAD TROUGH OF LOW PRESSURE ORIENTED NORTH TO SOUTH.
401 AM EDT MON AUG 3 2015 WEAK LOW PRESSURE WILL LIFT NORTHEASTWARD ACROSS THE FLORIDA PANHANDLE TODAY THEN ALONG THE COAST TONIGHT INTO TUESDAY. A BROAD UPPER TROUGH EXTENDED ACROSS THE EASTERN PART OF THE COUNTRY. THE DEEPEST MOISTURE IS EXPECTED TO REMAIN TO OUR SOUTH AND EAST BUT LIKELY WILL INCREASE A BIT AS THE LOW LIFTS NORTHWARD. TEMPERATURES SHOULD BE A FEW DEGREES COOLER TODAY GIVEN RELATIVELY CLOUDY START DUE TO STRATUS AND MOSTLY CLOUDY SKIES THROUGH MUCH OF THE DAY.
H7-H5 LAPSE RATES ARE A LITTLE STEEPER, HOWEVER THE FREEZING LEVEL MAY CLIMB ABOVE 15KFT FOR THE FIRST TINE IN A FEW DAYS. INTO TONIGHT AND TUESDAY, THE PANHANDLE LOW MOVES NORTHEAST TO THE GA/SC COAST AS THE RIDGE AXIS POKES DEEPER INTO CENTRAL FLORIDA.
351 AM CDT MON AUG 3 2015 THE UPPER LEVEL RIDGE OF HIGH PRESSURE CENTERED OVER THE SOUTHERN PLAINS WILL EXTEND EAST ACROSS THE MID SOUTH TODAY THROUGH TUESDAY.
340 AM EDT MON AUG 3 2015 DRIER AND COOLER CONDITIONS ARE EXPECTED TODAY AS HIGH PRESSURE BUILDS INTO THE GREAT LAKES. POTENT SW TROUGH ROUNDING SRN EXTENSION OF UPR LOW OVR HUDSON BAY QUICKLY ON THE WAY OUT EARLY THIS AM. OTRWS TEMPS MUCH COOLER TDA COMPARED TO YDAS HOT TEMPS AS LL CAA WRAPS SWD ESP THIS AFTN IN TANDEM W/PASSAGE OF SECONDARY CDFNT.
219 AM EDT MON AUG 3 2015 A COLD FRONT APPROACHES TODAY AND TONIGHT. WAVES OF LOW PRESSURE WILL PULL THE FRONT BACK NORTH MID TO LATE WEEK. A COLD FRONT. AND MAY EVEN HAVE SOME LOWER CLOUDS HANG OUT ACROSS THE HIGHER TERRAIN COUNTIES FOR A BIT OVERNIGHT. WITH MODELS HOLDING ON THE COLD FRONT PASSAGE INTO THE FAR SOUTHERN ZONES OF WEST VIRGINIA.
131 AM EDT MON AUG 3 2015 A WEAK PRESSURE TROUGH WILL REMAIN IN THE FORECAST AREA THROUGH TUESDAY. MOISTURE TRANSPORT AHEAD OF THE LOW COULD BRING MORE SHOWERS/TSTMS TO THE EASTERN MIDLANDS LATE TONIGHT. KEPT LOWS IN THE LOW/MID 70S. MODELS SUGGEST WEAK LOW PRESSURE OVER FLORIDA PANHANDLE AREA WILL MOVE NORTHEAST ALONG THE SOUTH CAROLINA COASTAL FRONT MONDAY AND MONDAY NIGHT. MODELS HAVE BEEN CONSISTENT SHOWING A RIDGE OVER THE CENTRAL US WITH A BROAD TROUGH ALONG THE EAST COAST.
LOOK FOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS TODAY AS AN UPPER LEVEL LOW WITH ASSOCIATED SUB- TROPICAL MOISTURE MOVES INTO SOUTHEAST IDAHO.
304 PM MST SUN NOV 8 2015 UPPER RIDGE IN PLACE ACROSS THE SOUTHERN ROCKIES OVERNIGHT WILL MOVE EASTWARD MON. UPPER LOW DEEPENS. WHERE READINGS WILL LIKELY STAY A FEW DEGF ABOVE FREEZING. WESTERN UPPER LOW BEGINS TO DROP SOUTHEASTWARD TOWARD THE GREAT BASIN. MAX TEMPS MON NEAR TO JUST A COUPLE DEGF COOLER THAN TODAY. AS 700 MB THERMAL RIDGE SLIDES EASTWARD INTO THE CENTRAL PLAINS BY AFTERNOON.
Near normal temperatures will dominate as a weak dry trough finishes passes over the Central Plains. Moisture is with this trough is mostly restricted to the far western edge of the trough, so little in the way of cloud cover is anticipated for Monday.
GIVEN THE FORECAST POSITION OF THE LOW. THE HIGHEST RAIN CHANCES THIS GO AROUND WILL BE HIGHER FOR OUR EASTERN AREAS.
WHICH HAS THE HIGHEST RAIN TOTALS JUST EAST OF THE AREA. BUT THIS AREA DID NOT RECEIVE THE HIGHEST RAIN TOTALS IN THE LAST WEEK AND SHOULD BE ABLE TO HANDLE MUCH OF THE RUNOFF.
GUIDANCE HAS BEEN TOO LOW WITH LOW TEMPERATURES THUS WILL GO WARMER THAN PREVIOUS FORECAST WITH READINGS IN THE LOWER 40S TO LOWER 50S.
AN APPROACHING COLD FRONT WILL CAUSE INCREASING SOUTH TO SOUTHWEST WINDS MONDAY AFTERNOON AND NIGHT.
A BIT LIGHTER WINDS WEST OF THIS AREA AND TEMPS MORE IN THE LOWER TO MID 50S IN THE VALLEY CITY TO GRAND FORKS TO HALLOCK AREA. BUT WITH MILD AIRMASS IN PLACE DO LOOK FOR LOWS TO BE A TAD MILDER STILL THAN LAST NIGHT WITH MOST SITES STAYING ABOVE FREEZING. THUS A BIT COOLER IN AREAS ALONG THE CANADIAN BORDER BUT STILL MILD AND AROUND 60 IN THE FAR SOUTHERN VALLEY AND WCNTRL MN.
THESE CONDITIONS ARE EXPECTED TO CONTINUE THROUGH TOMORROW WITH A BROAD UPPER LEVEL RIDGE IN PLACE. MONDAY AND MONDAY NIGHT AS OUR STRONG FALL STORM SYSTEM DEVELOPS OVER THE WEST COAST AND ROCKIES WE REMAIN UNDER THE INFLUENCE OF UPPER LEVEL RIDGING. SOUTHERLY FLOW EXPECTED TO PERSIST TUE/TUE NIGHT IN ADVANCE OF SIGNIFICANT TROF APPROACHING FROM THE INTER-MOUNTAIN WEST. ESPECIALLY WITH SURFACE TEMPS LIKELY HOLDING A FEW DEGREES ABOVE FREEZING. IT NOW APPEARS THAT THERE WILL BE SUFFICIENT COOLING ALOFT TO SUPPORT MOSTLY SNOW WITH THE SECOND UPPER LEVEL TROF.
SCATTERED TO NUMEROUS SHOWERS ARE EXPECTED TONIGHT AND MONDAY AS AN UPPER TROUGH MOVES ACROSS THE AREA. PRECIPITATION HAS BECOME MORE SHOWERY THRU THE DAY AS THE UPPER TROF CONTINUES TO SHIFT E TOWARD THE PACIFIC COAST. SNOWFALL AMOUNTS AT HIGHER ELEVATIONS WILL TOTAL 1 TO 3 INCHES WITH A FEW HIGHER RIDGES RECEIVING AS MUCH AS 4 OR 5 INCHES. ISOLATED STORMS WILL BE POSSIBLE OVER THE MAINLAND ON MON AS DAYTIME HEATING INCREASES INSTABILITY AS TROF MOVES OVERHEAD. THE FOCUS WILL SHIFT TO OVERNIGHT LOWS AND THE POTENTIAL OF FROST OR FREEZING TEMPERATURES. THE LOWER CONDITIONS WILL BE DUE TO REDUCED CEILINGS AND/OR VISIBILITIES AS SHOWERS MOVE ACROSS THE AREA AT TIMES. SEAS WILL PEAK TODAY AND MONDAY IN THE WAKE OF A WEAK COLD FRONT WHICH MOVED THROUGH THE WATERS LAST NIGHT.
WV imagery this afternoon shows an upper low moving over the southern Central Plains into the Missouri valley. Highs have risen into the upper 50s to low 60s, with winds a little stronger out west where high plains lee trough pressure gradient is tighter. For the rest of tonight, upper low ends up centered over Eastern Kansas and surface winds once again become light and decouple, and anticipate lows to still fall into the upper 20s east to mid/upper 30s in the west. As the low passes east on Monday, weak upper ridge moves in behind and boosts mid level temps a few degrees C.
THOUGH UPPER AIR AND SATELLITE DATA SHOW AN AREA OF LOW PRESSURE SPINNING NEAR THE KS/OK BORDER. SET UP BETWEEN HIGH PRESSURE OVER THE MIDWEST AND A TROUGH OF LOW PRESSURE DRAPED THROUGH THE HIGH PLAINS. SITTING IN THE LOWER/MID 60S.
LOW PRESSURE SYSTEM OVER THE NORTH CENTRAL GULF PROGGED TO LIFT OUT TO THE NE TONIGHT AS AN UPPER TROF EMBEDDED WITHIN THE SOUTHERN STREAM TRANSLATES EASTWARD ACROSS THE GULF COAST STATES. THIS WILL YIELD A RELATIVELY FLAT LOW TO MID LEVEL RIDGE UNDERNEATH FAST WESTERLY FLOW ALOFT TO START THE WORK WEEK.
825 PM EST SUN NOV 8 2015 HIGH PRESSURE AND A DRY AIRMASS WILL MOVE EAST TONIGHT. AN AREA OF LOW PRESSURE WILL PROVIDE WIDESPREAD SHOWERS MONDAY AFTERNOON THROUGH MONDAY NIGHT.

532 PM CST SUN NOV 8 2015 VFR CONDITIONS SHOULD PREVAIL AT ALL THREE TERMINALS NEXT 24 HOURS AS UPPER LOW DIGS INTO THE DESERT SOUTHWEST. /ISSUED 341 PM CST SUN NOV 8 2015/ TONIGHT WILL NOT LIKELY BE AS COOL WITH SURFACE RIDGING SLIDING EAST OF THE AREA. UPPER LEVEL SHORT WAVE RIDGING WILL MOVE IN TONIGHT AND TOMORROW IN THE WAKE OF A LOW BEING PINCHED OFF NORTHEAST OF THE REGION. A DEEP UPPER LEVEL TROUGH MOVING ONSHORE ON THE WEST COAST WILL ENCOURAGE DEVELOPMENT OF SURFACE CYCLOGENESIS IN THE LEE OF THE ROCKIES.
LEE TROUGHING HAS STRENGTHENED OVER EASTERN CO/EASTERN NM WITH HIGH PRESSURE OVER THE OHIO VALLEY. RETURN FLOW WILL CONTINUE TO STRENGTHEN INTO TUE AS A DEEP TROUGH DIGS OVER CA AND EVENTUALLY INTO THE DESERT SW. MODELS HAVE SLOWED DOWN THIS TROUGH SLIGHTLY COMPARED TO YESTERDAYS RUNS WITH THE DRYLINE SURGING THROUGH THE FORECAST AREA WED MORNING. THE BIGGER STORY WITH THIS POWERFUL LOW WILL BE STRONG NORTHWEST WINDS WED AFTERNOON/EVENING AS THE LOW LIFT OFF TO THE NORTHEAST. UPPER RIDGING OVER THE ROCKIES WILL FOLLOW BEHIND THIS WAVE SETTING UP DRY CONDITIONS AND ABOVE NORMAL TEMPS FOR THE WEEKEND. A LEE SIDE SURFACE TROF WILL GRADUALLY DEEPEN OVER THE HIGH PLAINS WHICH WILL RESULT IN A TIGHTER GRADIENT AND INCREASING SOUTHERLY WIND FLOW ACROSS THE AREA.
552 PM EST SUN NOV 8 2015 HIGH PRESSURE AND A DRY AIRMASS WILL MOVE EAST TONIGHT. AN AREA OF LOW PRESSURE WILL PROVIDE WIDESPREAD SHOWERS MONDAY AFTERNOON THROUGH MONDAY NIGHT.
WV Imagery indicates a weak upper level ridge of high pressure transitioning eastward across the Central Plains. Meanwhile, an upper level trough of low pressure is digging southeast across the Pacific Northwest and northern California. Near the surface, a lee side trough of low pressure is anchored across extreme eastern Colorado. This will lead to south winds and mild temperatures trough Monday. Highs Monday should reach into the lower to mid 60s.
TEMPERATURES WERE IN THE LOWER 60S. THE SURFACE MAP SHOWED DRY HIGH PRESSURE CENTERED OVER THE UPPER OHIO VALLEY. A LOW PRESSURE CENTER WAS LOCATED ALONG THE GULF COAST WITH A WEAK INVERTED TROUGH EXTENDING UP TOWARD TN. AN UPPER LEVEL LOW PRESSURE SYSTEM FROM OK/TX WILL MOVE ENE TO THE OHIO VALLEY.

549 PM CST SUN NOV 8 2015 The sky can't get much clearer than it has been so far today, with central Illinois remaining along an axis of high pressure extending east to near Pittsburgh. These will continue to be drawn northward ahead of an upper low that is slowly moving east-northeast from the central Plains. Pcpn associated with the inverted trough will spread northwestward toward the area. Once this brief system gets well east of the area southerly winds and warmer temps will slowly begin to return to the region. Temps on Tue will be warmer/above normal for the area and looking for around 60 possible.
Will issue another Freeze Warning for portions of northeast Oklahoma and northwest Arkansas as near freezing and sub-freezing temperatures are forecast.
913 PM EST SUN NOV 8 2015 HIGH PRESSURE OVER THE REGION WILL SLIDE OFFSHORE ON MONDAY AND MONDAY NIGHT.
SUSCEPTIBLE RADIATIONAL COOLING SPOTS SUCH AS RIVER VALLEY AND NORTHEAST LOCATIONS LIKELY TO DROP INTO THE LOWER 30S OVERNIGHT WHILE MOST OTHER AREAS REMAIN IN THE MID 30S THROUGH MONDAY MORNING. THE BIGGEST CHANGE TO THE MODELS SOLUTION IS THAT THE EURO IS A LITTLE FURTHER NORTH WITH THE LOW.
UPPER LOW ACROSS THE PLAINS EXPECTED TO WORK EAST AND BOTH OF THESE ESPECIALLY OVERNIGHT. TEMPERATURES WERE IN THE LOWER 60S. THE SURFACE MAP SHOWED DRY HIGH PRESSURE CENTERED OVER THE UPPER OHIO VALLEY. A LOW PRESSURE CENTER WAS LOCATED ALONG THE GULF COAST WITH A WEAK INVERTED TROUGH EXTENDING UP TOWARD TN.
