AN UPPER LEVEL RIDGE WILL BE OVER THE PACIFIC NORTHWEST FOR ONE MORE DAY TODAY.
127 AM EDT SAT MAY 9 2015 A COLD FRONT WILL APPROACH THE AREA FROM THE NORTHWEST TONIGHT AND EARLY SATURDAY AS AN UPPER LEVEL RIDGE MOVES EAST TO NEW ENGLAND.
322 AM EDT SAT MAY 9 2015 WEAK HIGH PRESSURE REMAINS OVER THE REGION THROUGH THE WEEKEND WHILE A FRONTAL BOUNDARY REMAINS TO THE NORTH. LOW PRESSURE.
417 AM EDT SAT MAY 9 2015 SHORT TERM FORECAST CONTINUES TO SHOW GEORGIA SQUEEZED BETWEEN UPPER LOW TO THE EAST AND SUB-TROPICAL STORM ANA OFF THE CAROLINA COAST. AND IN PORTIONS OF CENTRAL GEORGIA INTO THE LOW 90S TODAY AND SUNDAY.
1031 PM PDT FRI MAY 8 2015 High pressure builds into the region through the weekend, resulting in declining winds, mostly clear skies and warming temperatures.
258 AM EDT SAT MAY 9 2015 UPPER LEVEL RIDGING WILL HOLD OVER THE AREA THROUGH THE WEEKEND WITH THE CONTINUATION OF MILD SUMMER-LIKE WEATHER. THE RIDGE WILL BREAK DOWN A BIT MORE BY SUNDAY AND COULD LEAD TO SLIGHTLY BETTER COVERAGE FOR SHOWERS AND STORMS DURING THE AFTERNOON/EVENING HOURS. GOING WITH PERSISTENCE ON TEMPERATURES AS WE SHOULD SEE HIGHS REMAIN IN THE MID TO UPPER 80S THIS WEEKEND WITH OVERNIGHT LOWS IN THE 50S VALLEYS TO 60S RIDGES. THE UPPER LEVEL LOW CURRENTLY OVER THE FOUR CORNERS REGION WILL BE FILLING AS IT LIFTS INTO THE NORTHERN PLAINS BY THE BEGINNING OF THE PERIOD SUNDAY NIGHT. THE LOW EVENTUALLY BECOMES AN OPEN WAVE AS IT PROGRESSES ACROSS THE GREAT LAKES REGION SQUASHING THE UPPER LEVEL RIDGE WHICH HAS BROUGHT US THE UNSEASONABLY WARM WEATHER OF LATE.
MOSTLY CLOUDY SKIES WILL CONTINUE INTO SATURDAY MORNING WITH FAIR SKIES RETURNING FOR THE REST OF THE WEEKEND AS HIGH PRESSURE BUILDS INTO THE REGION.
319 AM CDT SAT MAY 9 2015 THE UPPER RIDGE THAT HAS BEEN DOMINATING THE WEATHER IS FINALLY BREAKING DOWN AND SHIFTING OFF TO THE EAST WHILE SUBTROPICAL STORM ANA CONTINUES TO ROTATE OFF THE SOUTH CAROLINA COAST.
THE FORECAST AREA WILL REMAIN POSITIONED UNDER UPPER LEVEL RIDGING THROUGH MUCH OF THE WEEKEND. THIS IS THANKS TO LONGWAVE TROUGHING AND AN UPPER LEVEL LOW SITTING TO OUR WEST AND SUBTROPICAL STORM ANA MEANDERING ABOUT OFF THE COAST OF THE CAROLINAS. DISTURBANCES ALOFT LIFTING NORTHEAST ON THE WESTERN PERIPHERY OF THE RIDGE WILL CAUSE SOME SHOWER ACTIVITY TO MOVE INTO MY WESTERN ZONES DURING THE PERIOD. THIS ACTIVITY SHOULD DISSIPATE AS IT MOVES TOWARD THE INTERSTATE 55 CORRIDOR WHERE IT'LL FURTHER ENCOUNTER THE UPPER RIDGE. THE RIDGE WILL BEGIN TO SLIDE EAST LATE SUNDAY AS THE BEFORE MENTIONED MID/UPPER LOW DEEPENS AND EJECTS NORTH NORTHEAST THROUGH THE PLAINS AND TOWARDS THE UPPER MISSISSIPPI RIVER VALLEY AND GREAT LAKES REGION. CAUSING THE TROUGH TO PUSH EAST.
249 AM PDT SAT MAY 9 2015 High pressure builds into the region through the weekend, resulting in declining winds, mostly clear skies and warming temperatures.
440 AM CDT SAT MAY 9 2015 COLD FRONT FROM YESTERDAY WAS REINFORCED BY OUTFLOW. AND IS IN THE PROCESS OF BEING OVERTAKEN BY INCOMING PACIFIC COLD FRONT. THREAT ENDS ABRUPTLY BY 7 PM WHEN MORE STABLE AIR ARRIVES WITH PACIFIC COLD FRONT.
458 AM EDT SAT MAY 9 2015 RIDGE OF HIGH PRESSURE ALOFT WILL GRADUALLY WEAKEN. TODAY WILL BE JUST A FEW DEGREES COOLER THAN YESTERDAY. MINIMUM TEMPERATURES WILL BE ABOUT 20 DEGREES WARMER THAN SEASONAL NORMALS. TEMPERATURES WILL BE A BIT COOLER THAN TODAY BUT STILL WELL ABOVE SEASONAL NORMALS.
315 AM EDT SAT MAY 9 2015 A LARGE RIDGE OF HIGH PRESSURE WILL MAINTAIN FAIR AND WARM WEATHER OVER THE REGION THROUGH THIS WEEKEND.
A STRONG UPPER LEVEL RIDGE WILL BRING WARM AND DRY WEATHER TO WESTERN WASHINGTON TODAY. AN UPPER LEVEL LOW APPROACHING THE REGION WILL INCREASE THE ONSHORE FLOW TONIGHT THROUGH SUNDAY NIGHT BRINGING COOLER TEMPERATURES AND INCREASING CLOUDS.
STRONG UPPER LOW MOVING INTO THE FOUR CORNERS REGION EARLY THIS MORNING WILL BEGIN A TURN TO THE NORTHEAST MOVING INTO CENTRAL SOUTH DAKOTA BY LATE SUNDAY. LIKELY GETTING SOME SNOWFALL IN THE HIGHER NORTHEAST FACING FOOTHILL LOCATIONS. FOCUS WILL THEN SHIFT TO NORTHEAST WYOMING AND FAR SOUTHEAST MT LATER TODAY AND INTO SUNDAY AS UPPER LOW BEGINS TO LIFT NORTHEAST. PERSISTENT RAINS INTO NORTHERN WY AND SOUTHEAST MONTANA ARE EXPECTED TO TRANSITION TO MOSTLY ALL SNOW FOR THIS REGION TONIGHT WITH DYNAMICAL COOLING AROUND UPPER LOW. ANTICIPATE THE BEST ACCUMULATING SNOWS INTO THE HIGHER FOOTHILL LOCATIONS SUCH AS STORY TODAY INTO TONIGHT.
315 AM CDT SAT MAY 9 2015 WATER VAPOR IMAGERY CURRENTLY SHOWS THE UPPER LOW APPROACHING THE FOUR CORNERS REGION. BEST GUESS IS THAT THE COLD FRONT STRETCHES FROM EASTERN MO ACROSS NORTHERN OK WITH IT WASHING OUT OVER THE TX PANHANDLE. MUCH COOLER AND DRIER AIR WILL BE SPILLING INTO THE AREA.
NOT MUCH PATTERN CHANGE IN THE SHORT TERM AS THE PINCHED UPPER RIDGE WILL CONTINUE OVER THE AREA. AND BEST INSTABILITY WILL LIKELY AGAIN BE OVER THE HIGHER TERRAIN AND NORTH.
400 AM EDT SAT MAY 9 2015 * HIGH WATERSPOUT RISK OFF SE FLORIDA COAST THIS MORNING * ISOLATED TSTORMS POSSIBLE INTERIOR-EAST COAST THIS AFTERNOON AND TONIGHT EAST COAST/SE FL WATERS * STRONG TSTORMS POSSIBLE SUN-MON OVER THE INTERIOR THE UPPER LOW WHICH HAS BEEN SPINNING ACROSS THE SOUTHWEST ATLANTIC AND PRODUCING A MEAN WEST-NORTHWEST WIND FLOW ACROSS FLORIDA WILL GRADUALLY LIFT NORTH-NORTHEAST AND AWAY FROM FLORIDA TONIGHT- SUNDAY.
ELEVATED THUNDERSTORM ACTIVITY IS EXPECTED THIS EVENING AS THE LOW LEVEL JET DEVELOPS. BY SUNDAY MORNING, THE UPPER LOW WILL BE OVER THE NORTHEAST CORNER OF COLORADO AND WILL BE LIFTING INTO THE EASTERN DAKOTAS BY SUNDAY EVENING. EARLY ON, SOME WRAPAROUND SHOWERS WILL BE POSSIBLE OVER WEST CENTRAL KANSAS BUT THESE SHOULD BE ENDING FAIRLY QUICKLY AS THE UPPER LOW MOVES OUT. THROUGH THE REMAINDER OF THE DAY, WESTERN KANSAS WILL BE UNDER CYCLONIC MID LEVEL FLOW IN THE WAKE OF THE UPPER LOW. COOLER, DRIER AIR WILL BE SPREADING INTO THE AREA BUT WE SHOULD SEE PERIODS OF CLOUDS ALONG WITH BREEZY CONDITIONS ESPECIALLY WITH MAX HEATING DURING THE DAY.
AND A BACK INTO NORTH CENTRAL OHIO CLOSER TO THE BROAD TROF AXIS. ANOTHER LULL IN PRECIPITATION IS EXPECTED TONIGHT WITH THE FIRST WAVE LIFTING NORTH AND BRIEF RIDGING ALOFT. INSTABILITY DRIVEN SHOWERS WILL AGAIN BE COMMON WITH SPATIAL COVERAGE EXPECTED TO INCREASE AS THE HIGH PRESSURE ERODES FURTHER.
OUR REGION LIES BETWEEN A GULF AND A WESTERN ATLANTIC RIDGE.
1250 AM CDT SAT MAY 9 2015 FOR 06Z TAFS /ISSUED 908 PM CDT FRI MAY 8 2015/ WE REMAIN SANDWICHED BETWEEN SUBTROPICAL STORM ANA TO OUR EAST AND A LOW PRESSURE SYSTEM ACROSS THE CENTRAL PLAINS. A LARGE COMPLEX OF THUNDERSTORMS HAS FORMED NEAR THE LOW TO OUR WEST.
400 AM CDT SAT MAY 9 2015 A SOUTHWEST TO NORTHEAST ORIENTED UPPER LEVEL RIDGE AXIS WILL REMAIN PARKED OVER THE AREA FOR TODAY AND TOMORROW.
A large upper closed low pressure system over the Great Basin will slowly move eastward today.
THE 10 PM EDT REGIONAL SURFACE ANALYSIS SHOWED A BROAD, WEAK AREA OF HIGH PRESSURE ACROSS MUCH OF THE SOUTHEAST, EXCEPT FOR LOWER PRESSURE OFF THE CAROLINAS ASSOCIATED WITH SUBTROPICAL STORM ANA. VAPOR IMAGERY AND UPPER AIR DATA SHOWED A RIDGE FROM THE TX COAST TO SOUTHEAST CANADA, AND A CUTOFF LOW OVER THE FOUR CORNERS REGION.
406 AM EDT SAT MAY 9 2015 A WARM FRONT WILL SLOWLY CROSS THE REGION TODAY. A COLD FRONT WILL APPROACH NORTHERN AREAS THIS EVENING.
An upper trough will begin to move over the region this afternoon with the base of the trough passing over the CWA. High winds at the base of the trough will mix downward over the Guadalupe Mountains this afternoon. Due to model persistence in showing these high winds, decided to upgrade the High Wind Watch to a High Wind Warning for the Guadalupe Pass. Temperatures this afternoon will be slightly cooler than yesterday as lower 500 mb heights move over the region. The upper trough will be over the central conus on Sunday with the dryline quickly mixing eastward during the afternoon.
STRONG UPPER RIDGE CENTERED OFFSHORE WITH A DRY NORTHERLY FLOW OVER THE REGION TONIGHT INTO SATURDAY. THE RIDGE REMAINS OVER THE FORECAST AREA SUNDAY WITH AN UPPER LOW APPROACHING THE PACIFIC NORTHWEST.
403 AM MDT SAT MAY 9 2015 AN ACTIVE WEATHER SCENARIO WILL UNFOLD TODAY AS A STRONG UPPER LOW OVER ARIZONA MOVES SLOWLY NORTHEAST TO COLORADO BY THIS EVENING. A VIGOROUS SHORT WAVE TROUGH WILL LIFT OUT AHEAD OF THE UPPER LOW EARLY THIS MORNING WHICH WILL BRING A ROUND OF PRECIP AFTER DAYBREAK. BUT AS THE FIRST TROUGH APPROACHES AM ANTICIPATING DEVELOPMENT OF ELEVATED SHOWERS AND THUNDERSTORMS STARTING IN OUR SW COUNTIES BY 6 AM AND WORKING UP TO I-70 BY MID-MORNING. AS THE UPPER LOW APPROACHES COLORADO LATER TODAY. 0-6 KM WIND SHEAR WILL INCREASE TO 70 KTS BY MIDDAY AS A STRONG 500 MB JET WORKS IT WAY AROUND THE UPPER LOW AND SPREADS ACROSS THE AREA.
411 AM EDT SAT MAY 9 2015 WEAK HIGH PRESSURE REMAINS OVER THE REGION THROUGH THE WEEKEND WHILE A FRONTAL BOUNDARY REMAINS TO THE NORTH. LOW PRESSURE.
ADDITIONAL ELEVATED THUNDERSTORMS MAY INCREASE IN COVERAGE AND PERHAPS INTENSITY OVER THE NEXT SEVERAL HOURS IN WESTERN NORTH TEXAS AS THE LOW LEVEL JET INCREASES. DAMAGING WIND AND TORNADO THREAT REMAINS VERY LOW HOWEVER AS THE LOW LEVELS SHOULD REMAIN STABLE.
539 AM EDT SAT MAY 9 2015 WEAK HIGH PRESSURE REMAINS OVER THE REGION THROUGH THE WEEKEND WHILE A FRONTAL BOUNDARY REMAINS TO THE NORTH. LOW PRESSURE.
ALL QUIET ON THE RADAR AGAIN EARLY THIS MORNING AS THE AREA IS STILL CONTROLLED BY HIGH PRESSURE. THIS ALL INDICATES THAT THE AXIS OF THE UPPER RIDGE HAS SHIFTED EAST ALLOWING BETTER CHANCES OF SHOWERS AND THUNDERSTORMS THIS WEEKEND. AND A BACK INTO NORTH CENTRAL OHIO CLOSER TO THE BROAD TROF AXIS. ANOTHER LULL IN PRECIPITATION IS EXPECTED TONIGHT WITH THE FIRST WAVE LIFTING NORTH AND BRIEF RIDGING ALOFT. BY MIDDAY SUNDAY ANOTHER SHORWAVE WILL ATTEMPT TO ROUND THE BROAD RIDGE. INSTABILITY DRIVEN SHOWERS WILL AGAIN BE COMMON WITH SPATIAL COVERAGE EXPECTED TO INCREASE AS THE HIGH PRESSURE ERODES FURTHER.
221 AM EDT SAT MAY 9 2015 A LARGE RIDGE OF HIGH PRESSURE WILL MAINTAIN FAIR AND WARM WEATHER OVER THE REGION THROUGH THIS WEEKEND.
359 AM EDT SAT MAY 9 2015 HIGH PRESSURE WILL REMAIN OVER THE MID-ATLANTIC TODAY.
408 AM CDT SAT MAY 9 2015 STRONG UPPER CLOSED LOW SPINNING ACROSS THE SOUTHWESTERN CONUS WILL INDUCE SURFACE CYCLOGENESIS ACROSS THE FRONT RANGE TODAY WITH THE BULK OF THE ACTIVITY WEST OF THE FORECAST AREA. AS THE WARM FRONT SHIFTS FROM SOUTH TO NORTH THROUGH THE AREA. THIS WOULD PUT THE HEAVIEST RAINFALL POTENTIAL MORE OVER CENTRAL NEBRASKA WHICH IS ALSO WHERE THE LOW LEVEL JET APPEARS MAXIMIZED. AS THIS FEATURE MOVES THROUGH SEVERE WEATHER WILL BE POSSIBLE AS THE ATTENDANT COLD FRONT/DRYLINE SHIFTS FROM WEST TO EAST THROUGH EASTERN NEBRASKA AND WESTERN IOWA.
THE LOW RH. ANOTHER FLY IN THE OINTMENT TO ALL OF THIS IS THE HIGH CLOUDS. /ISSUED 309 AM CST SAT JAN 30 2016/ MAIN CONCERN AGAIN TODAY WILL BE WITH REGARDS TO FIRE WEATHER AND THEN EARLY THIS UPCOMING WEEK WITH STORM SYSTEM THAT WILL BRING MUCH COOLER TEMPERATURES AND A CHANCE FOR RAIN/SNOW. THESE CONDITIONS ALONG WITH THE PERSISTENT OVERDOING OF THE LOW LEVEL MOISTURE BY THE MODELS SETS THE STAGE FOR PARTS OF FAR WESTERN OKLAHOMA AND WESTERN NORTH TEXAS TO AGAIN SEE RED FLAG CONDITIONS DEVELOP DURING THE AFTERNOON HOURS.
BY MIDDAY SUNDAY AN APPROX 1000MB FRONTAL WAVE WILL BE RIPPLING TOWARD LOWER MICHIGAN, THE WARM FRONT SERVING AS A FOCUS FOR LIFT ALONG THE NORTHERN PERIPHERY OF THE LOW-LEVEL JET. THE MOST FAVORABLE DYNAMICS, INCLUDING A SECOND SURGE OF RIGHT ENTRANCE SUPPORT AND ASSOCIATED FGEN, WILL RESIDE ALONG/NORTH OF THE LOW TRACK WHICH IS MODELED TO TRANSLATE FROM CHICAGO TO SAGINAW BAY 18-00Z, LEAVING JUST A SLIVER OF THE NW CWA IN A MORE FAVORABLE LOCATION TO SEE A 0.
Trailing portion of associated cold front will sag south into the Big Country during the day Sunday. Temperatures will be cooler across our far northern counties Sunday, and to a lesser extent toward the I-20 corridor. We'll also see a few cold fronts in the area, with the strongest front arriving midweek. The first cold front will be in the area Sunday evening, resulting in light winds during the overnight hours.
BY EARLY MORNING, CONFIDENCE REMAINS HIGH ENOUGH TO INCLUDE IFR CIGS AT PNC AND GAG/WWR BEHIND A COLD FRONT. IT IS CURRENTLY UNCLEAR HOW FAR SOUTH THE LOW CIGS WILL MAKE IT AFTER SUNRISE TOMORROW.
259 PM CST SAT JAN 30 2016 A weak cold front is expected to move across the area late tonight and early tomorrow morning.
SINCE THIS WIND CORE WILL BE SLOW TO TRANSLATE EAST TODAY AHEAD OF A MINOR TROUGH OBSERVED IN NORTH-CENTRAL NM AT NOON.
WARMING AND MODERATING TO BEGIN IN EARNEST SUNDAY AS VEERING E-SE LOW LEVEL FLOW AROUND WESTERN ATLANTIC HIGH PRESSURE RIDGE AXIS INCREASES MOISTURE WHILE HIGH TEMPS CLIMB INTO THE MID TO UPPER 70S MOST AREAS TO NEAR 80 DEGREES IN EXTREME SOUTHERN AREAS BY SUNDAY AFTERNOON.
351 PM EST SAT JAN 30 2016 HIGH PRESSURE ALONG THE COAST WILL GRADUALLY MOVE OFFSHORE TONIGHT THROUGH SUNDAY NIGHT.
TEMPERATURES WERE 7-11 DEGREES WARMER THAN THIS TIME YESTERDAY. OTHERWISE A WARMER DAY ON TAP FOR THE AREA. TEMPERATURES HAVE BEEN MODERATING OVER THE PAST 24 HOURS AS DEWPOINTS HAVE CREPT INTO THE LOWER 50S ACROSS SE TEXAS.
THE LOW STRATUS DECK SHOULD BEGIN TO LIFT BACK TO BETWEEN 2500 AND 4000 FEET AFTER 15Z TOMORROW.
234 PM EST SAT JAN 30 2016 HIGH PRESSURE WILL SHIFT OFF THE EAST COAST LATE TODAY AND SUNDAY.
High pressure builds into the area tomorrow with decreasing cloudiness through afternoon.
THE OPPOSITE IS TRUE FARTHER NORTH WHERE RH VALUES HAVE BEEN SLOW TO DECLINE WITH COMPARABLY COOLER TEMPS. A COLD FRONT /CURRENTLY DIVING TOWARD THE COLORADO PALMER DIVIDE/ SHOULD ENTER THE NRN TX PANHANDLE BEFORE STALLING NW-SE OVER OUR SWRN COUNTIES BY LATE MORNING SUNDAY. DECENT PRESSURE RIDGING AND COOLER THICKNESSES SHOULD KEEP THIS BOUNDARY MORE PERSISTENT THAN THE ONE EXPERIENCED LAST NIGHT. UPSHOT OF THIS BEING HIGH TEMPS SHOULD FARE 10-20 DEGREES COOLER OVER ALL BUT OUR SW ZONES PROVIDED THE FRONT STALLS ALONG OR JUST SW OF HIGHWAY 84.
239 PM CST SAT JAN 30 2016 MOSTLY SUNNY CONDITIONS PREVAIL ACROSS MOST OF THE HUN CWFA THIS AFTERNOON, WITH HIGH PRESSURE CENTERED OFF THE SOUTHEAST COAST AND INCREASING SOUTHWEST FLOW LOCALLY. THE UPGLIDE WILL PERSIST SUNDAY, BUT MOISTURE AND LIFT WILL INTENSIFY SUNDAY NIGHT AHEAD OF AN APPROACHING COLD FRONT.
WINDS WILL BE STRONGEST ALONG AND EAST OF THE CENTRAL MOUNTAIN CHAIN AND OVER THE HIGHER TERRAIN OF WESTERN NEW MEXICO DURING THE AFTERNOON. THE STRONG WINDS WILL CONTINUE ACROSS THE HIGHER TERRAIN OVERNIGHT.
TEMPERATURES HAVE ALREADY RISEN INTO THE LOWER 40S TO AROUND 50 DEGREES ACROSS NORTHERN ALABAMA.
WHILE RADAR RETURNS CURRENTLY LOOK GOOD AROUND THE MOBRIDGE AREA. AFTER THAT A WEST COAST TROUGH DEEPENS AND THE UPPER LEVEL FLOW TRANSITIONS TO THE SOUTHWEST OVER THE PLAINS STATES. WHILE SLIGHTLY COOLER.
AHEAD OF THE SYSTEM WIDESPREAD COLD- TOPPED CLOUDINESS WAS OVER THE CENTRAL AND NORTHERN ROCKIES AND THE HIGH PLAINS INTO CENTRAL NEBRASKA. THERE IS NO INDICATION OF A WARM LAYER OVER THE COLD LAYER AND FREEZING PRECIPITATION IS UNLIKELY.
CLOUDS ARE ON THE INCREASE SUNDAY NIGHT AS AN UPPER LEVEL TROUGH AND ASSOCIATED COLD FRONT SWINGS DOWN INTO OUR REGION OUT OF THE OHIO RIVER VALLEY.
TEMPERATURES IN MANY LOCATIONS WEST OF I-65 ARE ALREADY IN THE LOWER 60S.
THE WEAK COLD ADVECTION CONTINUES TONIGHT INTO SUNDAY WITH SLIGHTLY COOLER HIGHS ANTICIPATED FOR SUN. THIS FA WILL BE UNDER WEAK HIGH PRESSURE.
WITH PINE RIDGE REPORTING RAIN. TODAY THROUGH SUNDAY NIGHT 09Z SURFACE ANALYSIS HAD TROUGH FROM EASTERN MT INTO EASTERN CO. UPPER TROUGH PASSES WITH CONTINUED CHANCES OF PRECIPITATION. UPPER TROUGH OVER THE WEST COAST DEEPENS SIGNIFICANTLY AS MAJOR JET STREAK PLOWS INTO CA.
Southerly flow will advect more moisture into the region overnight, resulting in higher dewpoints and low temperatures 5 to 10 degrees warmer than this morning.
318 PM EST SAT JAN 30 2016 WARMER WEATHER IS EXPECTED UNTIL A STRONG COLD FRONT PASSES MIDWEEK.
ONE COLD FRONT WILL MOVE THROUGH THE AREA SUNDAY BRINGING SOME RAIN TO THE AREA.
312 PM EST SAT JAN 30 2016 A WARM FRONT WILL LIFT THROUGH THE REGION TONIGHT ALONG WITH SOME LIGHT SNOW SHOWERS. MUCH WARMER THAN NORMAL TEMPERATURES ARE EXPECTED ON SUNDAY ALONG WITH DRY WEATHER.
High pressure builds into the area tomorrow with decreasing cloudiness through afternoon. Based on the cooling in the 0-1km layer by the GFS and NAM along with some breaks of sun during the afternoon it appears that the highs on Sunday will range from the mid 40s to the lower 50s.
BUT AS LOW LEVEL FLOW VEERS EAST-NORTHEAST, WE SHOULD BE ABLE TO GET TEMPERATURES A FEW DEGREES WARMER IN THE LOW 70S WITH THE HIGH CLOUDS BEING THE LIMITING FACTOR.
103 PM EST SAT JAN 30 2016 WARMER WEATHER IS EXPECTED UNTIL A STRONG COLD FRONT PASSES MIDWEEK.
A BROAD UPPER LEVEL TROUGH IS SETTLING OVER THE REGION. THIS IS BRINGING COOLER SHOWERY WEATHER TO THE REGION. EXPECT SHOWERS TO INCREASE DURING THE AFTERNOON AS SURFACE HEATING BEGINS TO FURTHER DESTABILIZE THE LOWER ATMOSPHERE.
153 PM EST SAT JAN 30 2016 HIGH PRESSURE MOVES ACROSS SOUTHERN VIRGINIA AND EASTERN NORTH CAROLINA TODAY. THE HIGH REMAINS OFF THE COAST SUNDAY.
AS COOL UNSTABLE AIR COMES IN UNDER UPPER TROUGH OVER THE NW STATES. MAIN ENERGY OF THE TROUGH WILL GO WELL TO OUR SOUTH SUNDAY INTO SRN CALIF AND ARIZONA BEFORE MOVING EAST.
An unstable trough of low pressure will be the dominant feature over the Northern Rockies the remainder of the weekend. As a ridge of high pressure builds along the west coast, northwest flow will linger over western Montana and central Idaho.
HAVE UPDATED THE SUITE OF FORECAST PRODUCTS FOR LATE AFTERNOON INCREASING CLOUD COVERAGE ACROSS WRN PORTIONS OF MID STATE PER WEAK UPPER LEVEL TROUGH MOVING AT LEAST ACROSS THIS PORTION OF MID STATE.
223 PM EST SAT JAN 30 2016 A WARM FRONT WILL CROSS THE REGION TONIGHT AND SUNDAY.
230 PM EST SAT JAN 30 2016 HIGH PRESSURE WILL CONTINUE TO SHIFT OFFSHORE TONIGHT AND SUNDAY. BUT PRECIP CHANCES WILL BEGIN TO INCREASE SUNDAY NIGHT AS A COLD FRONT APPROACHES FROM THE WEST. NAM IS PRETTY AGGRESSIVE WITH BRINGING IN THE RETURN MOISTURE OVERNIGHT ALONG WITH SOME OF THE HIGHER RES MODELS.
A COLD FRONT MOVES THROUGH THE PANHANDLES TONIGHT WHICH WILL KNOCK BACK OUR HIGH TEMPERATURES BY ABOUT 20 DEGREES.
1215 PM EST SAT JAN 30 2016 THE AVIATION SECTION HAS BEEN UPDATED BELOW A COLD FRONT IS EXPECTED TO PASS THROUGH THE AREA SUNDAY NIGHT.
A LOW PRESSURE SYSTEM WILL MOVE NORTHEAST FROM THE SOUTHERN PLAINS SUNDAY CAUSING CLOUDY SKIES WITH RAIN LIKELY BY AFTERNOON.
THIS WILL ALLOW A COLD FRONT TO PUSH SOUTHWARD THROUGH THE FORECAST AREA. WITH BRISK NORTHERLY WINDS AND COOLER AIR ADVECTION.
1101 AM MST SAT JAN 30 2016 UPPER FLOW WILL BE ZONAL THROUGH SUNDAY NIGHT AHEAD OF A TROUGH MOVING INTO NEVADA.
439 PM EST SAT JAN 30 2016 HIGH PRESSURE WILL SHIFT OFF THE EAST COAST LATE TODAY AND SUNDAY.
1243 PM EST SAT JAN 30 2016 A PRESSURE RIDGE WILL MOVE OFF THE SOUTHEAST COAST TODAY.
Today should feature another day of well-above average temperatures, with readings ranging from the low to mid 60s north to near 70 south. This wave will force a cold front south through the area during the day Sunday. Right now it looks like temps will range from the low 50s northwest to low 60s southeast, though any change in the strength and/or timing of the frontal passage would require adjustments.
1109 AM EST SAT JAN 30 2016 HIGH PRESSURE WILL SHIFT OFF THE EAST COAST LATE TODAY AND SUNDAY.
WE HAVE INCREASED THE HIGHS BY A DEGREE OR TWO FOR THE WESTERN THIRD OF THE AREA WHERE SOME LOW 80S WILL BE POSSIBLE THIS AFTERNOON. THIS WILL SEND A COLD FRONT SOUTH TO NEAR OR JUST SOUTH OF THE I-20 CORRIDOR. COOLER AIR BEHIND THE FRONT WILL KEEP HIGHS IN THE 60S ALONG THE RED RIVER SUNDAY WITH MORE 70S EXPECTED ELSEWHERE.
A WEAK COLD FRONT WILL ENTER NORTH TEXAS SUNDAY MORNING AND MOVE THROUGH THE SOUTHEASTERN PARTS OF THE FORECAST AREA SUNDAY AFTERNOON.
A STRONG COLD FRONT WILL MOVE SOUTH ACROSS CENTRAL UTAH TODAY AND STALL OVER SOUTHERN UTAH TONIGHT.
HIGH PRESSURE CURRENTLY IN CONTROL OF THE AREA WILL SLOWLY SLIDE TO THE EAST OVER THE WEEKEND AS AN UPPER TROUGH APPROACHES FROM THE WEST. THIS TROUGH WILL BE ENOUGH TO GENERATE SOME ISOLATED TO SCATTERED SHOWERS ON SUNDAY GENERALLY ACROSS THE NORTHERN HALF OF THE AREA.
Given the improving westerly flow across the Rockies along with the expected mixing depth and warming in the 0 to 1 km layer advertised by the NAM and GFS will trend towards the warmer MAV guidance for highs today despite some increasing high clouds during the afternoon hours. Tonight a cold front will drop south across western Kansas as a weak upper level disturbance crosses the Northern Plains. Based on the cooling in the 0-1km layer by the GFS and NAM along with some breaks of sun during the afternoon it appears that the highs on Sunday will range from the mid 40s to the lower 50s.
SURFACE FLOW TURNS SOUTHERLY TODAY ALLOWING ONLY SLIGHTLY WARMER TEMPERATURES WITH HIGHS 10 TO 15 DEGREES ABOVE NORMAL. A WEAK MID LEVEL IMPULSE MOVING ACROSS THE PLAINS MIXES A DRYLINE EAST ACROSS MUCH OF OUR AREA ON SUNDAY LEADING TO LOWER DEWPOINTS AND AN EVEN WARMER AIRMASS AS FLOW BECOMES DOWNSLOPE.
The weak cold front that moved through overnight wont bring much if any cold air south today, so expectations remain that readings will warm back at least into the 50s, with some areas likely to bubble up near 60 across eastern Kansas and far western Missouri. Some isentropic up-glide ahead of the trough may generate some showers in areas near the Iowa border Sunday morning; but in general most areas will be dry with overall cooler readings thanks to the cloud cover and weak surface winds.
150 PM EST SAT JAN 30 2016 HIGH PRESSURE OFF THE SOUTHEAST COAST WILL EXTEND INTO THE FORECAST AREA THROUGH SUNDAY.
PERSISTENT STREAM OF MID-LVL CLOUDS IS HOLDING TEMPERATURES NEAR OR ABOVE FREEZING. THE BEST GUIDANCE THE PAST DAYS HAVE BEEN THE WARMER NUMBERS. PRECIPITATION FALLING INTO THE DRIER SUB- CLOUD LAYER WILL TRY TO WET-BULB TOWARDS THE FREEZING LVL. BUT THE ADVECTION OF MORE MOIST AIR IN THE LOWER LVLS WILL MAKE IT DIFFICULT FOR SOUNDINGS TO TRANSITION TOWARDS ANY WINTRY MIX.
AT THE SURFACE AND IN THE LOWER TO MID LEVELS. A RIDGE OF HIGH PRESSURE IS DEVELOPING ACROSS CENTRAL FLORIDA AND THE WESTERN ATLANTIC WITH NEAR 1025 MB NEAR ORLANDO ATTM.
322 PM EST SAT JAN 30 2016 HIGH PRESSURE WILL SHIFT OFF THE EAST COAST LATE TODAY AND SUNDAY.
/ISSUED 456 AM CST SAT JAN 30 2016/ LEE-SIDE LOW PRESSURE OVER EASTERN COLORADO WILL HELP MAINTAIN A TIGHT SURFACE PRESSURE GRADIENT OVER THE AREA TODAY.
/ISSUED 331 AM EST SAT JAN 30 2016/ A QUIET WEATHER PATTERN WILL CONTINUE UNDER WEAK HIGH PRESSURE INFLUENCE.
WARMER AIR WILL PUSH HIGHS INTO THE 40S TODAY AND SUNDAY BEFORE COLDER AIR WRAPS IN BEHIND THE DEPARTING LOW.
with a cold front passing through KBVO around 15-16z.
HIGHS WILL BE WELL ABOVE SEASONAL NORMS FOR THIS TIME OF YEAR AND IT IS HIGHLY LIKELY THAT AFTERNOON READINGS IN THE LOW 70S WILL ONCE AGAIN BE SEEN.
MADE SOME ADJUSTMENTS TO TEMPERATURES WITH COOLER CONDITIONS OVER THE SOUTHWEST AND SOUTH CENTRAL WHERE THE SNOW FELL. WARMER ACROSS THE NORTH WITH A LOT MORE SUNSHINE. A MIX OF RAIN AND SNOW REMAINS PRUDENT IN THE FORECAST IN PLACES WHERE WE DO HAVE POPS GIVEN THERMAL PROFILES NEAR THE FREEZING MARK. EARLY THIS MORNING A WEAK UPPER LEVEL SHORT WAVE TROUGH WAS PUSHING ACROSS EASTERN MONTANA. FREEZING RAIN. SLEET AND SNOW IS POSSIBLE WITH TEMPERATURES ALOFT WITHIN ONE OR TWO DEGREES OF FREEZING AND SURFACE TEMPERATURES ALSO HOVERING AROUND FREEZING. THE 00 UTC GLOBAL MODEL SUITE REMAINED IN GOOD AGREEMENT WITH ITS DEPICTION OF NORTHWEST FLOW ALOFT DEVELOPING ACROSS THE REGION AS A MEAN 500-MB TROUGH BECOMES ESTABLISHED OVER THE CENTRAL UNITED STATES THIS WEEK.
A WEAK WARM FRONT WILL PRODUCE SOME SCATTERED LIGHT SNOW SHOWERS THIS AFTERNOON.
234 PM EST SAT JAN 30 2016 HIGH PRESSURE OFF THE SOUTHEAST COAST WILL EXTEND INTO THE FORECAST AREA THROUGH SUNDAY.
202 PM EST SAT JAN 30 2016 A HIGH PRESSURE SYSTEM, WILL PUSH OFF THE EAST COAST TODAY.
UPPER LOW OVER THE QUEEN CHARLOTTES THIS MORNING WILL SETTLE SEWD AND BECOME AN OPEN TROUGH OVER THE INTERMOUNTAIN WEST TONIGHT AND SUNDAY.
Unseasonably warm temperatures are expected again, even warmer than yesterday.
107 PM EST SAT JAN 30 2016 WARMER WEATHER IS EXPECTED UNTIL A STRONG COLD FRONT PASSES MIDWEEK.
