125 AM MST SUN FEB 8 2015 HIGH PRESSURE WILL CONTINUE TO DOMINATE THE WEATHER OVER THE REGION FOR THE NEXT SEVERAL DAYS RESULTING IN MOSTLY CLEAR SKIES AND MUCH ABOVE NORMAL TEMPERATURES. HIGH TEMPERATURES IN THE LOWER TO MIDDLE 80S WILL BE COMMON BEFORE A SLIGHT COOLING TREND BY THE MIDDLE OF THE WEEK. STRONG HIGH PRESSURE RIDGING AND DEEP SUBSIDENCE CONTINUES TO PREVAIL OVER THE SWRN CONUS AS REPEATED DISTURBANCES LIFT NORTHEAST FROM THE PACIFIC BASIN INTO CNTRL AND NRN CALIFORNIA.
WINDS ARE FROM THE WEST/NORTHWEST AND A LITTLE GUSTY BEHIND THE TROUGH. WE START OUT SUNDAY NIGHT WITHIN NORTHWEST FLOW AHEAD OF AN APPROACHING RIDGE. THE RIDGE AXIS IS NOT EXPECTED TO CROSS THE CWA UNTIL AT LEAST MONDAY NIGHT. BUT POTENTIALLY A BIT COOLER IN THE MID 40S IN OUR NORTHEAST WHERE THERE COULD STILL BE SOME SNOW PACK.
TEMPS SOME 20 DEGREES ABOVE SEASONAL NORMS WILL CONT THROUGH TUES BEFORE COLD FRONT DROPS TEMPS BACK CLOSER TO NORMAL. NO COLD AIR ASSOCIATED WITH THIS TROUGH AND TEMPS WILL BE SIMILAR TO TODAY IN MANY LOCATIONS.
A cold front will push through the area around mid-day accompanied by northerly gusts to around 20 kts. A cold front will move south through the area tomorrow shifting southwesterly winds to the north with associated gusts to 15 to 20 kts. /ISSUED 329 PM CST Sat Feb 7 2015/ (Tonight and Sunday) The low clouds have finally dissipated, yielding sunny skies this afternoon across West Central Texas. An hour or two of low clouds may make as a far west as San Angelo, however boundary layer flow will veer quickly to west-southwest keeping the low clouds further east. For Sunday, A cold front will move south across West Central Texas. Another nice day in store with highs ranging from the lower 60S across the Big Country to the lower 60S along the I-10 corridor.
SHORT TERM: (Through Late This Afternoon) (Today) Stratus has finally developed over the lower Mississippi Valley over the past couple of hours. Attendant surface cold front is still progged to come through the mid-Mississippi Valley today. Boosted highs several degrees for the southeastern 2/3 of the day based on starting off warmer than expected and latest RAP/HRRR guidance.
HIGH PRESSURE OVER THE SOUTHEAST U. A COLD FRONT WILL DROP SOUTH TOWARD THE FORECAST AREA. TEMPERATURES WILL BE PLEASANT FOR ONE MORE DAY WITH HIGHS IN THE LOW TO MID 60S. BY SUNDAY NIGHT THE COLD FRONT WILL BE MOVING THROUGH THE FORECAST AREA WITH ANOTHER CHANCE OF LIGHT RAIN AHEAD OF THE FRONT. TEMPERATURES WILL BE A LITTLE COOLER THAN TONIGHT WITH LOWS MONDAY MORNING IN THE LOW TO MID 40S. THE COLD FRONT WILL BE MOVING OUT OF THE REGION AND WHAT RAIN IS OVER THE FORECAST AREA WILL BE ENDING IN THE MORNING. COOLER AIR WILL MOVE INTO THE REGION BEHIND THE FRONT BUT TEMPERATURES WILL STILL BE CLOSE TO NORMAL LEVELS WITH HIGHS IN THE UPPER 40S TO MID 50S. HIGH PRESSURE WILL MOVE INTO THE REGION MONDAY NIGHT BRINGING CLEAR SKIES.
227 AM EST SUN FEB 8 2015 HIGH PRESSURE WILL REMAIN TO OUR NORTH THROUGH MONDAY AS WEAK LOW PRESSURE TRACKS ALONG A FRONTAL BOUNDARY OFF THE COAST.
BUT MVFR CIGS ARE EXPECTED TO ARRIVE IN THE EVENING AS A LOW PRESSURE SYSTEM APPROACHES FROM THE WEST.
WEAK RIDGING ALOFT AND HIGH PRESSURE AT THE SURFACE WILL KEEP THE REGION DRY WITH NEAR NORMAL TEMPERATURES THROUGH THE END OF THE PERIOD.
WILL CANCEL THE FREEZING RAIN ADVISORY FOR FAR SOUTHEASTERN ND EARLY AS THE PRECIPITATION HAS MOVED SOUTH OF THE AREA.
AND INTO THE 50S AND 60S FOR THE HIGH VALLEYS. BRISK W-NW FLOW ALOFT IS EXPECTED TO CONTINUE INTO THE EVENING FOR THE HIGHER TERRAIN AND IMMEDIATELY ADJACENT PLAINS AS AN UPPER DISTURBANCE DROPS DOWN ACROSS THE NORTHERN ROCKIES. AND THE HIGHEST PEAKS MAY SEE UP TO AN INCH OF NEW SNOW BY SUNDAY MORNING. SLIGHTLY COOLER TEMPS AND WEAKER WINDS FORECAST FOR TOMORROW MEAN NO HIGHLIGHT AT THIS TIME.
COOLER BUT ABOVE NORMAL TEMPERATURES WILL FOLLOW WITH HIGHS ON SUNDAY RANGING FROM THE MID 40S IN OUR EAST TO THE MID TO UPPER 50S IN OUR WEST.
HIGH PRESSURE ALOFT WILL MOVE OVER THE AREA OVERNIGHT FOR A PERIOD OF DRY WEATHER ON SUNDAY. THE LAST IN THE SERIES OF LOW PRESSURE SYSTEMS WILL IMPACT THE REGION SUNDAY NIGHT AND MONDAY.
THE IMPRESSIVE EARLY FEBRUARY THERMAL RIDGE WILL SLIDE SOUTH AHEAD OF THE FRONT. BRINGING IN A WEDGE OF RELATIVELY COOLER AIR WHEN COMPARED TO THE LAST COUPLE OF DAYS. BRUNT OF ANY APPRECIABLY COOLER CANADIAN AIR WILL REMAIN WELL OFF TO THE NORTHEAST WITH THE CORE OF THE RESPONSIBLE UPPER DISTURBANCE JOURNEYING THROUGH THE CENTRAL PLAINS INTO THE MID MISSISSIPPI AND OHIO VALLEYS. RENEWED RIDGING WILL TAKE SHAPE ACROSS THE ROCKIES DOWNWIND OF A WEST COAST STORM SYSTEM AS SURFACE WINDS BECOME LIGHT OVERNIGHT UNDER THE INFLUENCE OF WEAK SURFACE RIDGING. SHOULD THEREFORE SEE TEMPERATURES A TOUCH COOLER FOR MONDAY MORNING AS RADIATIONAL COOLING TAKES HOLD. RIDGE AXIS WILL STILL BE TO OUR WEST EXTENDING FROM CHIHUAHUA TO MONTANA THENCE UP THE WEST COAST OF CANADA.
WITH TEMPERATURES STAYING ABOVE THE FREEZING MARK CENTRAL AND SOUTH THROUGH THE EVENING THE MELTING WILL CONTINUE. COOLER NW FLOW WILL MOVE BACK ACROSS THE NORTH BY MORNING. PUSHED BY A MODEST 500 MB TROUGH CROSSING THE REGION. PROFILES SUGGEST SOME POTENTIAL FOR FREEZING DRIZZLE INITIALLY. BUT WITH TEMPERATURES IN THE LOWER 30S AT SUNRISE AND CREEPING UP SLOWLY DURING THE DAY IT IS BELIEVE THAT ANY PRECIP WILL SWITCH OVER TO LIQUID BY AROUND MIDDAY. AS THE 500 MB TROUGH MOVES AWAY FROM IOWA ON SUNDAY NIGHT THE LIGHT PRECIP WILL GRADUALLY END.
THE HIGH PRESSURE RESPONSIBLE FOR THE TIGHTENED GRADIENT HAS SHIFTED EAST INTO THE WESTERN NORTH ATLANTIC. AND SURFACE OBSERVATIONS PLACES A WEAK TROUGH IN THE SOUTHERN GULF AND THE YUCATAN CHANNEL. THIS TROUGH HAS SETUP CAMP UNDERNEATH A BROAD AND WEAK UPPER LEVEL TROUGH.
AN ASSOCIATED WEAK COLD FRONT WILL CAUSE WINDS TO VEER AND SLIGHTLY COOLER ALBEIT STILL WELL ABOVE NORMAL TEMPERATURES TOMORROW.
AN UPPER LEVEL RIDGE CONTINUES ABOVE THE WESTERN UNITED STATES DURING THE SHORT TERM PERIOD WITH AN UPPER LEVEL LONG WAVE TROUGH ACROSS THE EASTERN UNITED STATES. MOSTLY CLEAR SKIES CONTINUE OVERNIGHT WITH THE RIDGE OF HIGH PRESSURE SLIDING SOUTH OF THE AREA. COOLER TEMPERATURES ARE EXPECTED TODAY WITH HIGHS REACHING TO AROUND 70 DEGREES. HIGHS WILL RANGE FROM THE LOW TO MID 70S FAR WEST TO THE MID 60S ACROSS SOUTH CENTRAL SECTIONS OF KANSAS.
THE TROUGH MOVES EAST OF THE I-35 CORRIDOR EARLY THIS EVENING. SLIGHTLY COOLER AND DRY ON MONDAY.
HELPING MIXING IN THE LOW LEVELS. THE COLD FRONT WILL MOVE IN MONDAY MORNING. BRINGING AN END TO THE WARMER THAN AVERAGE TEMPERATURES.
246 AM CST Sun Feb 8 2015 A broad area of low pressure over the plains will slowly shift to the east through the day today. This will bring a cold front through the Ozarks late this morning into early this afternoon. Confidence is on the low side however and any drizzle that does develop will be short lived. The cold front will make its way thorough all of the Ozarks by late this afternoon with cooler temperatures filtering into the area along with clearing skies for much of the overnight hours.
424 AM EST SUN FEB 8 2015 HIGH PRESSURE WILL EXTEND OVER THE AREA FROM THE SOUTHEAST THROUGH TONIGHT.
306 AM CST SUN FEB 8 2015 COLD FRONT APPROACHING FROM THE NORTHWEST IS ONLY A COUPLE OF COUNTIES AWAY FROM THE NORTHWEST EDGE OF THE FORECAST AREA. LIKELY TO WARMER LEVELS THAN THE LAST COUPLE OF DAYS DESPITE BEING POST FRONTAL. THE WARMER/DRIER CONDITIONS BEHIND THE FRONT. COOLER.
WATER VAPOR WAS ALSO SHOWING ANOTHER MID-LEVEL TROUGH MOVING THROUGH THE NORTHERN ROCKIES WHICH WILL HAVE AN IMPACT ON US BY SUNDAY MORNING WITH PERHAPS A WINTRY MIX OF PRECIPITATION. WARMER AIR IS OFF THE SURFACE AROUND 0. SOUNDING THERMAL PROFILE SHOW PRECIPITATION TYPE COULD BE TRICKY WITH FREEZING RAIN/SLEET/SNOW ALL POSSIBLE. ANY FREEZING RAIN CLOUD PRODUCE SOME HEADACHES FOR A TIME SUNDAY MORNING BEFORE TEMPERATURES MODERATE TO ABOVE THE 32 DEGREE MARK. SINCE IF FREEZING RAIN IS REALIZED THERE MAY BE NEED FOR A POTENTIAL SHORT-TERM/MORNING HEADLINE. QUIET CONDITIONS INITIALLY ON MONDAY AS THE RIDGE PASSES OVERHEAD WITH HIGHS TOP OF IN THE 20S.
HIGH PRESSURE HAS SHIFTED OFF TO THE EAST AND PRESSURES ARE LOWERING IN THE PLAINS RESULTING IN RETURN FLOW WITH GUSTY WINDS NOTED IN THE NORTHERN AND WESTERN PORTIONS OF THE AREA. EXPECT SOME SEA FOG TO DEVELOP NEAR THE SOUTHEAST TEXAS/SOUTHWEST LOUISIANA COASTAL ZONES AS EARLY AS TOMORROW AFTERNOON AND MORE LIKELY TOMORROW NIGHT AHEAD OF A COLD FRONT.
WITH THE COLD FRONT ANTICIPATED TO MAKE ITS WAY ACROSS THE STATE LATER TODAY PUSHING ACROSS THE SOUTHERN PLAINS. THE AFOREMENTIONED COLD FRONT SHOULD REACH THE NORTHERN FORECAST AREA THIS EVENING.
This will allow a cold front to push south through West Central Texas this morning. Going for highs around 3 degrees cooler than GFS MOS high temperatures today, and closer to the cooler NAM. Winds of 15 to 20 mph will make it feel cooler. The moisture/inversion is very shallow, and is indicated to break between 9 AM and 10 AM, with surface heating and as gusty westerly winds move in ahead of the cold front. Surface ridging will build directly over the Big Country by 6 AM Monday, bringing good radiational cooling. While GFS MOS guidance appears to have allowed for strong radiational cooling with lows in the lower 40s, can not really rule out a few readings in the upper 30s in protected low lying areas.
THE IMPRESSIVE EARLY FEBRUARY THERMAL RIDGE WILL SLIDE SOUTH AHEAD OF THE FRONT. BRINGING IN A WEDGE OF RELATIVELY COOLER AIR WHEN COMPARED TO THE LAST COUPLE OF DAYS. BRUNT OF ANY APPRECIABLY COOLER CANADIAN AIR WILL REMAIN WELL OFF TO THE NORTHEAST WITH THE CORE OF THE RESPONSIBLE UPPER DISTURBANCE JOURNEYING THROUGH THE CENTRAL PLAINS INTO THE MID MISSISSIPPI AND OHIO VALLEYS. RIDGE AXIS WILL STILL BE TO OUR WEST EXTENDING FROM CHIHUAHUA TO MONTANA THENCE UP THE WEST COAST OF CANADA.
High pressure will continue to be the dominant feature with mostly clear skies and light winds.
1228 AM EST SUN FEB 8 2015 HIGH PRESSURE WILL KEEP THE WEATHER QUIET THROUGH THE TAF PERIOD.
351 AM CST SUN FEB 8 2015 MAIN HIGHLIGHT IS THE FREEZING RAIN ADVISORY STRETCHING FROM NORTHWEST THROUGH SOUTH CENTRAL NORTH DAKOTA THIS MORNING. HAVE CANCELLED THE FREEZING RAIN ADVISORY FOR THE FAR SOUTHERN JAMES RIVER VALLEY. USED THE WET BULB MAX TEMPS ALOFT FROM THE NAM TO DETERMINE PRECIPITATION TYPE TODAY AS IT SEEMED TO CAPTURE THE AREAL EXTENT OF THE FREEZING RAIN AREA THE BEST. WEST WINDS AND TEMPERATURES IN THE LOWER 40S IN FAR SOUTHWEST NORTH DAKOTA. SLEET/SNOW ACROSS NORTH CENTRAL NORTH DAKOTA AND LIGHT FREEZING RAIN OVER NORTHWEST THROUGH SOUTH CENTRAL NORTH DAKOTA. WILL CONTINUE WITH MILD TEMPERATURE TRENDS IN THE SOUTHWEST TODAY WILL HIGHS IN THE LOW TO MID 50S.
LOW PRESSURE IS EXPECTED TO MOVE EAST ALONG THE FRONT ON SUNDAY AFTERNOON.
IN ADVANCE OF A LOW PRESSURE SYSTEM TRACKING EASTWARD INTO THE OHIO VALLEY. WITH AN ATTENDANT COLD FRONTAL PASSAGE MONDAY NIGHT.
STRONG SUBSIDENCE/DRY LAYER REMAINS IN PLACE OVER OUR CWA BEHIND THIS TROUGH. WITH BUILDING HIGH PRESSURE FROM SOUTHEAST COLORADO.
LOW LEVEL MOISTURE WILL INCREASE AS A COLD FRONT APPROACHES. HIGH PRESSURE IS NOW CENTERED FAR TO OUR SOUTHEAST WITH A LOW PRESSURE SYSTEM BREWING OVER THE UPPER MIDWEST AND A STRENGTHENING PRESSURE GRADIENT BRINGING UNSEASONABLY WARM AIR INTO MIDDLE TENNESSEE THIS WEEKEND. TONIGHT'S TEMPERATURES WILL BE CONSIDERABLY WARMER, ONLY DROPPING INTO THE 40'S MOST AREAS, WITH READINGS TOMORROW ONCE AGAIN APPROACHING 60 DEGREES, DESPITE INCREASED CLOUDINESS AND A SLIGHT CHANCE OF RAIN. A COLD FRONT WILL SWEEP THROUGH THE MID STATE TOMORROW NIGHT, WITH A BIT BETTER CHANCE OF RAIN OVERNIGHT, ALTHOUGH THE QPF FOR THIS EVENT REMAINS RATHER LOW GIVEN THAT ONLY THE LOW LEVELS WILL BE SATURATED. TEMPERATURES STARTING OFF THE NEW WEEK WILL BE CONSIDERABLY COOLER.
WINDS REMAIN WESTERLY BEHIND THE EXITING LOW PRESSURE. SKIES WILL CONTINUE TO CLEAR TODAY AS HIGH PRESSURE MOVES IN. HIGHS WILL RANGE FROM THE MID 40S ACROSS NORTH CENTRAL SD TO THE LOWER 60S OVER FAR SOUTHWEST SD. FREEZING RAIN WILL BE POSSIBLE. SHOWING A SATURATED BOUNDARY LAYER BELOW FREEZING WITH WARMER AND DRIER AIR ALOFT. LOWS ACROSS NORTHWEST SD WILL BE AROUND FREEZING.
1037 PM CST SAT FEB 7 2015 UPDATED AVIATION PORTION FOR 06Z TAF ISSUANCE AND NEW INFORMATION ADDED TO UPDATE SECTION HAVE RECEIVED SEVERAL REPORTS OF FREEZING DRIZZLE OVER FAR NC/NE WI. 12Z INL/GRB/MPX SOUNDING HAD DRY AIR AT MID LEVELS WITH ABOVE FREEZING TEMPERATURES. HAVE A MENTION OF FREEZING RAIN OR ICE PELLETS. HAVE PRECIPITATION CHANCES OVER A LARGER PART OF THE FORECAST AREA WITH A MORE SIGNIFICANT SHORT WAVE ON SUNDAY THOUGH KEPT POPS ON THE LOW SIDE.
QUIET WEATHER IS EXPECTED FOR THE NEXT FEW DAYS AS UPPER LEVEL RIDGING PREVAILS OVER THE SOUTHERN PLAINS AND A REX BLOCK TAKES SHAPE OVER THE WESTERN CONUS.
08/06Z TAF CYCLE HIGH PRESSURE IS OFF TO THE EAST OF ARKANSAS WITH LOW PRESSURE TO THE WEST. A WEAK COLD FRONT WILL MOVE THROUGH THE STATE LATE IN THE PERIOD.
POPS RISE TO LIKELY BY MIDNIGHT AS QG FORCING INCREASES AHEAD OF THE MID-UPPER TROUGH. BUT IN GENERAL WE SHOULD SEE DECREASING RAIN CHANCES THROUGH MONDAY AFTERNOON WITH THE UPPER TROUGH AND SURFACE FRONT PASSAGE OCCURRING AROUND MIDDAY.
it will take a while for the cooler air to arrive tonight and mixing will remain good. to the lower 40s along and south of I 70. High temps are expected to range from the middle 50s in the far northeast corner near Hiawatha to the low to middle 60s across most of the remainder of the area.
THIS EVENING THROUGH SUNDAY NIGHT LOW AMPLITUDE UPPER RIDGING CONTINUES ACROSS THE CNTRL CONUS. TEMPS OVER THE WRN SD PLAINS HAVE REACHED AS HIGH AS THE LOW TO MID 70S. TEMPS WILL BE COOLER THAN THE PREVIOUS TWO DAYS.
254 AM MST SUN FEB 8 2015 NEAR RECORD WARMTH WILL CONTINUE THROUGH MONDAY AS HIGH PRESSURE BUILDS OVER THE REGION.
102 AM EST SUN FEB 8 2015 HIGH PRESSURE WILL PREVAIL THROUGH THE WEEKEND. A COLD FRONT WILL ADVANCE THROUGH THE REGION MONDAY.
301 AM CST Sun Feb 8 2015 Low pressure area and associated cold front will drop into the state this morning and then continue to move southeast through the day and then out of the CWA by late this afternoon. However, still lots of melting of the snow is occurring, and that is putting more moisture into the lower layers, so will keep patchy fog in the north third of the CWA, just for the morning hours. After that, the early part of the week looks quiet, as high pressure drifts across the Mississippi Valley. While the upper level pattern flattens out for a bit early this week, a ridge continues to be projected to build along the West Coast mid to late week.
Mid afternoon temperatures were in the middle 60s to the lower 70s across the area. As temperatures cool the low levels may saturate enough to create a low level stratus deck. Another relatively warm day is in store for Sunday as a cold front makes its way across the region. However expect any stratus to erode from the west pretty quickly as the low level flow veers with the approach of the front. There will be a substantial temperature gradient from southwest to northeast with highs Monday ranging from the lower 40s in the eastern Ozarks to the middle 50s near the Kansas and Oklahoma borders.
TODAY AND TONIGHT EARLY MORNING SURFACE OBS INDICATE A COLD FRONT SINKING SOUTH ACROSS THE PANHANDLES. LOWS TONIGHT SHOULD BE SLIGHTLY COOLER. RANGING FROM THE LOWER 30S TO THE LOWER 40S.
HIGH PRESSURE CONTINUES TO FLATTEN AS WIND FLOW BECOMES MORE ZONAL. A CHANCE REMAINS THIS AFTERNOON AND EVENING FOR SOME VERY ISOLATED SNOW SHOWERS/FLURRIES FOR THE HIGHEST ELEVATIONS OVER THE FLATTOPS AND NRN MTNS. THE JET WILL ALLOW ALSO FOR SOME GUSTY WINDS IN THE 30 TO 40MPH RANGE AT TIMES OVER THE HIGHEST ELEVATIONS. TEMPS WILL REMAIN WARM THOUGH A LITTLE COOLER TODAY AND TOMORROW BECAUSE OF INCREASED CLOUD COVER. 12Z MODELS LOOKING A BIT MORE IN AGREEMENT NOW WITH THE NEXT PACIFIC TROUGH ENTERING THE PACIFIC NORTHWEST ON MONDAY BEFORE DROPPING SOUTH AND REACHING NW MEXICO ABOUT THU.
AS THE DEVELOPING TROF SWINGS THRU TONIGHT, DRIER AND COOLER AIR WORKS ITS WAY IN TMRW, WITH A RETURN TO SEASONAL EARLY FEBRUARY TEMPS.
AS A WEAK CDFNT/UPPER TROF APPROACHES THE TN VALLEY BY SUNDAY AFTN.
1258 AM EST SUN FEB 8 2015 IT WILL REMAIN MILD WITH TEMPERATURES ABOVE FREEZING TONIGHT. LOCAL AREA TO REMAIN IN WARM SECTOR AND WITH SFC TEMPS EXPECTED ABOVE FREEZING ALONG WITH WARM AIR ALOFT. ANY PCPN SHOULD BE IN LIQUID FORM WITH NO FREEZING EXPECTED.
303 AM CST SUN FEB 8 2015 THE FOCUS IS ON THE THREAT OF FREEZING DRIZZLE. THERE HAVE BEEN REPORTS OF LIGHT FREEZING DRIZZLE EARLY THIS MORNING. SO THINK THE THREAT OF FREEZING DRIZZLE WILL GRADUALLY WEAKEN THROUGH THIS MORNING AS PCPN TYPE BEGINS TO MORE FAVOR SNOW BY LATER THIS MORNING. ONLY HAVE PATCHY FREEZING DRIZZLE IN THE FORECAST THROUGH MID MORNING. WEAK HIGH PRESSURE WILL MOVE INTO THE REGION TODAY. APPROACHING LOW PRESSURE COULD BRING SOME LIGHT SNOW OR EVEN SOME PATCHY FREEZING DRIZZLE TO KINL AND KBRD LATE IN THE NIGHT.
An upper trough continues to cause light snow showers/flurries and light rain showers/sprinkles across the area late this afternoon. The rest of the short term period is dry with high pressure remaining in control at the sfc and an upper trough aloft providing unseasonably cold temperatures for late Mar. Compromising with model data and NWS neighbors, gradually have clouds taper from west to east through the night which will result in low temps in the low to mid 20s. Northerly winds and the cold airmass should limit highs to the low to mid 40s. Another cold night awaits for Sat night with low temps again dipping into the lower 20s.
HIGH PRESSURE ALOFT WILL RESULT IN SUNNY AND WARM DAYS WITH NEAR RECORD HIGH TEMPERATURES EXPECTED OVER THE WEEKEND.
THE AXIS OF A LONGWAVE TROF OVER THE EASTERN STATES MOVES SLOWLY TO NEAR THE EAST COAST THROUGH SATURDAY. HIGHS ON SATURDAY WILL BE SIMILARLY BELOW NORMAL AND MAINLY IN THE LOWER/MID 60S.
1053 PM MDT FRI MAR 27 2015 SHORT TERM CONCERNS ARE DRIER AND WARMER CONDITIONS EXPECTED ON SATURDAY AFTERNOON. THE AXIS OF THE LARGE UPPER RIDGE CURRENTLY RESIDING OVER THE INTERMOUNTAIN AND ROCKY MOUNTAIN REGIONS MOVES EAST OVER THE NORTHERN AND CENTRAL PLAINS ON SATURDAY AS A TROUGH CUTS THROUGH THE APEX OF THE UPPER RIDGE OVER THE NORTHERN ROCKIES. THE COOLER HIGH PRESSURE AREA AT THE SURFACE CURRENTLY OVER THE PLAINS STATES IS SLIDING FURTHER TO THE EAST AS THE FRONTAL BOUNDARY THAT HAD BEEN ALONG THE FRONT RANGE THIS MORNING MOVES EAST ACROSS THE FORECAST AREA THIS AFTERNOON AND EVENING. THE RESULT IS TEMPERATURES WILL CONTINUE TO WARM THROUGH SATURDAY WITH WARMEST TEMPERATURES OVER THE WESTERN PORTIONS OF THE FORECAST AREA AND COOLER TEMPERATURES TO THE EAST.
HIGH PRESSURE ALOFT WILL CONTINUE TO MOVE FURTHER EAST OF THE AREA TO ALLOW FOR COOLER CONDITIONS THIS WEEKEND.
AN APPROACHING FRONTAL BOUNDARY WILL RESULT IN BREEZY WINDS AND WARMER AIR BEING PULLED UP INTO THE AREA SATURDAY.
Overnight lows tonight will be slightly warmer than last night, as low-level moisture begins to return.
MINIMUM TEMPERATURES SHOULD REMAIN ABOVE FREEZING OVERNIGHT.
Local temps were in the lower to middle 40s early this afternoon, with values topping the 60 degree mark in western portions of the state. The exit of this wave and drier air working in from the upper ridge should end any precip by dawn.
617 PM CDT FRI MAR 27 2015 12Z UA ANALYSIS HAS THE MAIN 850MB COLD FRONT FROM NEW ENGLAND TO THE GULF COAST WITH A SECONDARY FRONT FROM THE EASTERN GREAT LAKES INTO CENTRAL MISSOURI. 18Z SFC ANALYSIS HAS HIGH PRESSURE FROM LAKE SUPERIOR INTO THE SOUTHERN PLAINS. A WARM FRONT RAN FROM THE WESTERN DAKOTAS INTO WESTERN KANSAS. QUIET AND DRY CONDITIONS WILL CONTINUE FROM LATE AFTERNOON THROUGH MIDNIGHT AS THE HIGH SLOWLY MOVES EAST. QUIET AND DRY CONDITIONS WILL BE SEEN ON SATURDAY AS YET ANOTHER HIGH PRESSURE SLOWLY MOVES THROUGH THE MIDWEST.
VFR CAN BE EXPECTED THROUGHOUT THIS TAF PACKAGE WITH VERY DRY HIGH PRESSURE IN PLACE. HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN THROUGH THE WEEKEND WITH A WARMING TREND DEVELOPING TOMORROW.
The highly amplified upper level pattern over the CONUS will transition to a more w-e zonal flow with milder temperatures.
/ISSUED 337 PM CDT FRI MAR 27 2015/ THE SYNOPTIC PATTERN LATE THIS AFTN WAS COMPRISED OF UA TROUGHING ACROSS THE MID-WEST. AMPLIFIED UA RIDGING ACROSS THE WRN CONUS AND THUS NORTHWESTERLY FLOW ALOFT DOMINATING ACROSS THE SOUTHERN PLAINS. DESPITE THE PRESENCE OF THE COLD FRONT TEMPS MANAGED TO STILL WARM INTO THE 60S AND 70S. OVERNIGHT LOWS WILL BE MILDER THAN RECENT NIGHTS /UPPER 30S ACROSS THE SW TX PANHANDLE TO THE UPPER 40S ACROSS THE LOW ROLLING PLAINS/. EXPECT THIS WIND SHIFT TO HAVE LITTLE RESULTING IN HIGHS IN THE 80S /OR SOME 6-12 DEGREES WARMER THAN TODAY/.
LINGERING SWATH OF RAIN ACROSS SRN ZONES WITH FEW EMBEDDED SHRA IS ALL THAT REMAINS OF PRECIP ACROSS OUR REGION ASSOC W/ VIGOROUS UPPER LEVEL TROUGH. THE COLD FRONT IS NEAR THE CLEARING LINE ON THE SAT ACROSS NATURE COAST. FRONT WILL USHER MUCH COOLER AND DRIER AIR INTO THE REGION OVERNIGHT. SOME MVFR CONDITIONS IN FIRST FEW HOURS OF THE FORECAST PERIOD ACROSS CEN AND SW FL WILL IMPROVE AS COLD FRONT BRINGS DRIER CONDITIONS. /ISSUED 302 PM EDT FRI MAR 27 2015/ BANDS OF SHOWERS AND THUNDERSTORMS HAVE EXPANDED OVER THE COASTAL WATERS IN RESPONSE TO LARGE SCALE ASCENT FROM AN UPPER LEVEL TROUGH. SURFACE COLD FRONT IN BIG BEND AREA OF FLORIDA WITH TEMPERATURES RANGING FROM THE LOWER 60S IN THE PAN HANDLE TO NEAR 90 IN MIAMI. AN UPPER-LEVEL TROUGH EXTENDING OVER THE EASTERN U.
SOME LOCATIONS IN NORTHERN MISSISSIPPI HAVE SEEN SOME LIGHT SHOWERS THROUGH THE DAY AS AN UPPER TROUGH SWINGS ACROSS THE REGION. HIGH PRESSURE CENTERED OVER THE OHIO VALLEY HAS MOVED INTO THE REGION FOLLOWING YESTERDAYS FRONTAL PASSAGE. THIS HAS HELPED TO KEEP CONDITIONS COOLER TODAY THROUGH TONIGHT BUT OVERALL TEMPERATURES HAVE NOT BEEN TOO BAD ESPECIALLY IN LOCATIONS THAT HAVE SEEN A BIT OF SUN. IT STILL LOOKS LIKE ALL LOCATIONS SHOULD REMAIN ABOVE FREEZING BUT OUTLYING AREAS MAY DIP CLOSEST BUT STILL REMAIN ABOVE. IT WILL BE ANOTHER COOLER DAY ACROSS THE AREA AS HIGHS SHOULD REACH INTO THE 60S. WITH SOME SPOTS WARMER THAN TODAY. ANOTHER COLD NIGHT IS EXPECTED SATURDAY NIGHT WITH LOWS IN THE LOWER TO MID 40S.
1131 PM CDT FRI MAR 27 2015 AT H5 STRONG RIDGE OVER THE WESTERN CONUS WITH WAVE MOVING INTO THE TOP OF THE RIDGE OVER THE PACIFIC NORTHWEST. DEEP TROUGH OVER THE EASTERN CONUS WITH COLD FRONT AND PRECIPITATION OVER THE WESTERN ATLANTIC. WARM FRONT CONTINUES TO SLOWLY DRIFT EAST AND WILL STALL ACROSS CENTRAL/EASTERN NEB OVERNIGHT.
714 PM CDT FRI MAR 27 2015 EARLY AFTERNOON WATER VAPOR IMAGERY TOGETHER WITH GFS 500MB HEIGHTS AND WINDS IDENTIFIED A RIDGE ACROSS THE WESTERN CONUS. WITH A DEEP TROUGH EXTENDING OVER THE EASTERN HALF OF THE UNITED STATES. A SUBTLE SHORT WAVE WAS LOCATED IN THE NORTHWEST FLOW DOWNSTREAM OF THE RIDGE AXIS. BY SATURDAY MORNING SOUTH SOUTHEAST WINDS WILL INCREASE ACROSS THE REGION WHICH WILL LEAD TO DEEPER MIXING AND WARMER TEMPERATURES SATURDAY AFTERNOON.
1044 PM EDT FRI MAR 27 2015 CURRENTLY - A ROBUST COLD FRONT IS MARCHING THROUGH THE EXTREME SOUTHEASTERN GULF OF MEXICO. SHORT TERM UPDATE (OVERNIGHT) - MODERATE TO OCCASIONALLY FRESH WINDS WILL HOLD OUT OF THE WEST TO NORTHWEST UNTIL THE COLD FRONT PUSHES THROUGH THE KEYS. AND ONLY A CHANCE OF LIGHT RAIN IS EXPECTED ALONG AND NEAR THE COLD FRONT. THE STRONG COLD FRONT WILL THEN RUSH THROUGH ALL KEYS WATERS OVERNIGHT.
742 PM EDT FRI MAR 27 2015 A COLD FRONT HAS MOVED OFFSHORE.
HIGH PRESSURE REBUILDING BEHIND A COLD FRONT ALLOWING FOR NORTHWEST WINDS 10 TO 15 MPH WITH HIGHER GUSTS ACROSS NORTHEAST TEXAS AND SOUTHEAST OKLAHOMA.
731 PM EDT FRI MAR 27 2015 STRONG UPPER TROUGH WITH ABUNDANT VORT MAX ENERGY IS APPROACHING THE STATE AND CURRENTLY SPREADING ABUNDANT MID LEVEL CLOUDINESS INTO NORTH AND WEST CENTRAL GA. SO CANNOT RULE OUT A FEW SPRINKLES OF LIGHT RAIN THROUGH THE EVENING AS THE UPPER TROUGH AXIS MOVES ACROSS THE STATE. THE CLOUDS AND WINDS MAY HINDER SOME AREAS FROM REACHING FREEZING TONIGHT.
UPPER TROUGH AND ACCOMPANYING COLD FRONT ON TRACK TO PUSH THROUGH SE OREGON AND SW IDAHO EARLY SATURDAY MORNING. COLD FRONTAL SYSTEM WILL MOVE THROUGH REGION TONIGHT.
