A RIDGE WILL BUILD AROUND MID WEEK BRINGING WARMING AND DRYING FOR THE REMAINDER OF THE WEEK. ELSEWHERE RAINFALL AMOUNTS WILL VARY WIDELY FROM AN INCH OR TWO IN THE HIGHER TERRAIN OF HUMBOLDT AND TRINITY COUNTIES. RAIN WILL TAPER OFF TUESDAY AFTERNOON WITH MOST AREAS DRY BY TUESDAY EVENING AS AN UPPER RIDGE BUILDS INTO THE AREA.
THIS AFTERNOON/S SHORT WAVE TROUGH AND SHOWERS WILL EXIT EAST LATE TODAY. AFTER A FEW HOURS CLEARING FROM WEST TO EAST THE NEXT PACIFIC SHORT WAVE TROUGH WILL COME IN OVERNIGHT THROUGH TUESDAY WITH MORE SHOWERS. AND THAT TROUGH LOOKS WETTER THAN THE PREVIOUS TWO.
349 PM EDT MON MAR 23 2015 LOW PRESSURE CONTINUES TO MOVE EAST ALONG A STALLED BOUNDARY SITUATED ACROSS CENTRAL FLORIDA. HIGH PRESSURE WILL CONTINUE TO BUILD IN FROM THE NORTH AND THEN WEDGE IN FROM THE NORTHEAST OVERNIGHT INTO TUESDAY. SKIES SHOULD REMAIN CLOUDY/MOSTLY CLOUDY THROUGH THE REMAINDER OF THE SHORT TERM PERIOD AS THE EASTERLY FLOW CONTINUES AND THE LOW LEVEL MOISTURE INCREASES.
332 PM MDT MON MAR 23 2015 A FAST-MOVING COLD FRONT WILL BREEZE THROUGH THE AREA TONIGHT. WITH THE HIGHEST LOCAL AMOUNTS TO 6 INCHES IN THE HIGHER PEAKS OF ZONE 4.
1130 AM MDT MON MAR 23 2015 18Z TAF CYCLE UPPER JET ASSOCIATED WITH LARGE SWATH OF HIGH CLOUDS WILL CONTINUE TO SAG SOUTHEAST OVER NEW MEXICO THROUGH 24/02Z AS SFC LEE TROF REMAINS IN PLACE.
FAIRLY NEUTRAL ADVECTION FROM THE EAST OF 850 MB TEMPERATURES BETWEEN 6 AND 10 DEGREES SHOULD ALSO HELP TO KEEP HIGH TEMPERATURES COOLER IN GENERAL THAN NORMAL.
ANOTHER LOW PRESSURE SYSTEM WILL PUSH INTO THE AREA TOMORROW INTO TOMORROW NIGHT.
LOW CLOUDS WILL PERSIST THROUGH THE NIGHT AS A WEAK AREA OF LOW PRESSURE MOVES SOUTHEAST OF THE AREA.
243 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL KEEP OUR WEATHER QUIET BUT CHILLY TONIGHT THROUGH TUESDAY. WARMER AND WETTER WEATHER WILL ARRIVE BY THE MIDDLE OF THE WEEK. JUST AMAZING WHEN YOU CONSIDER NOT ONLY ITS MID MARCH BUT WE HAVE A HIGH SUN ANGLE AND FULL SUNSHINE! HIGH PRESSURE LOCATED NORTH OF LAKE HURON WILL BUILD SOUTH OVER THE AREA TONIGHT. HIGH PRESSURE AND THE CORE OF THE COLD AIR WILL SLIDE EASTWARD TUESDAY.
147 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL REMAIN NEARLY STATIONARY ACROSS THE EASTERN GREAT LAKES THROUGH TUESDAY.
WATER VAPOR IMAGERY AND UPPER AIR DATA SHOWING A LOW AMPLITUDE PATTERN OVER THE COUNTRY WITH WEAK TROUGHING IN THE EAST. WEAK RIDGING CENTRAL AND A NEGATIVE TILTED TROUGH MOVING INTO THE PACIFIC NORTHWEST. DECENT HEIGHT FALLS NOTED WITH THE WESTERN TROUGH AT 500 MB OF 50 TO 70 METERS IN THE LAST 12 HRS. LOW PRESSURE STRETCHED FROM WEST CENTRAL MONTANA TO THE TEXAS PANHANDLE.
234 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL KEEP OUR WEATHER QUIET BUT CHILLY TONIGHT THROUGH TUESDAY. WARMER AND WETTER WEATHER WILL ARRIVE BY THE MIDDLE OF THE WEEK. JUST AMAZING WHEN YOU CONSIDER NOT ONLY ITS MID MARCH BUT WE HAVE A HIGH SUN ANGLE AND FULL SUNSHINE! HIGH PRESSURE LOCATED NORTH OF LAKE HURON WILL BUILD SOUTH OVER THE AREA TONIGHT. HIGH PRESSURE AND THE CORE OF THE COLD AIR WILL SLIDE EASTWARD TUESDAY.
A SURFACE FRONTAL BOUNDARY OUT AHEAD OF IT LIES ROUGHLY THROUGH MONIDA PASS AND THE ARCO DESERT AREA WHICH IS HELPING TO SUPPORT SURFACE WIND GUSTS IN THE LOWER 40 MPH RANGE AND THOSE GUSTS MAY INCREASE SOME THE NEXT FEW HOURS AS THE JET NOSES INLAND.
THE OFFICIAL FORECAST IS WARMER THAN MOST GUIDANCE AND CALLS FOR 40-45 AREA WIDE. EASTWARD PROGRESSION OF THE RIDGE WILL GIVE WAY TO INCREASING HEIGHT FALLS AS THE AFOREMENTIONED SURFACE FRONT LIFTS TOWARD LOWER MICHIGAN. EVEN SO, LOSS OF THE LOW-LEVEL INVERSION AS THE THETA-E RIDGE FOLDS EAST ALONG WITH DEVELOPING LIGHT COLD ADVECTION WILL PROMOTE A WELL-MIXED ENVIRONMENT WITHIN WHICH WESTERLY FLOW WILL HAVE THE POTENTIAL TO GUST TO AT LEAST 30 MPH. LIGHT WINDS WILL PERSIST THROUGH TUESDAY AS HIGH PRESSURE OVER THE GREAT LAKES HOLDS FIRM.
DRY CANADIAN HIGH PRESSURE HANGS ON FOR ONE MORE DAY. HIGHS MAINLY IN THE LOW TO MID 40 EXCEPT COOLER NEAR THE LAKE.
As the low makes its way towards eastern Kansas, a warm front will begin to lift north across the Ozarks.
THE UPPER LEVEL TROUGH CONTINUES TO PROGRESS EASTWARD THIS AFTERNOON. SOME BREAKS ARE POSSIBLE LATE TONIGHT WITH CLEARING FROM THE WEST DURING THE DAY ON TUESDAY AS WEAK UPPER RIDGING BUILDS ACROSS THE AREA AND A DRIER AIRMASS CONTINUES TO MOVE INTO THE REGION. ONCE THE LOW CLOUDS SCATTERED OUT TUESDAY MORNING. TEMPS WILL WARM INTO THE LOW TO MID 70S UNDER PARTLY CLOUDY SKIES.
236 PM EDT MON MAR 23 2015 A WEAK COLD FRONT WILL MOVE THROUGH SOUTH FLORIDA OVERNIGHT, WITH SCATTERED SHOWERS AND PERHAPS A THUNDERSTORM. WITH THE BOUNDARY STALLING OR WASHING OUT OVER THE STRAITS TUESDAY MORNING, AND VERY SUBTLE LOW PRESSURE REMAINING OVER SOUTH FLORIDA, THERE COULD BE SOME REDEVELOPMENT OF SHOWERS TUESDAY ALONG THE SOUTHEAST FL COAST/UPPER KEYS, THEN A LITTLE FURTHER INLAND LATER IN THE AFTERNOON WITH WEAK SURFACE CONVERGENCE.
HIGH PRESSURE OVER ONTARIO WILL CAUSE FAIR WEATHER ACROSS OUR AREA TONIGHT. HIGHS TODAY WILL BE IN THE LOWER TO MIDDLE 30S. WITH LOWS TONIGHT IN THE LOWER TO MIDDLE 20S. AS THE SHRTWV MOVES EAST OF THE AREA AND RIDGING ALOFT BUILDS IN.
251 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL BUILD EAST TONIGHT AND TUESDAY.
FLAT RIDGING ALOFT WILL RESULT IN WARMER TEMPS AND DRY CONDITIONS THROUGH THE SHORT TERM. MODELS PROG THE LOW LEVEL WINDS TO BE A TAD STRONGER TONIGHT ESPECIALLY ACROSS THE RIO GRANDE PLAINS. WITH A FEW LOCATIONS A DEGREE OR TWO WARMER THAN TODAY'S VALUES.
With the 850mb thermal ridge centered over the CWA tomorrow we can expect unseasonably warm temperatures continuing with morning lows and afternoon highs 10-15 degrees above normal.
SHORT TERM HIGH RES MODELS ARE IN AGREEMENT THAT FOG WILL ALSO DEVELOP ALONG THE SPINE OF THE BUFFALO RIDGE. THIS WILL BE PARTICULARLY CONCERNING IN SOUTHWEST MINNESOTA WHERE TEMPERATURES BEGIN THE DAY BELOW FREEZING AND ARE NOT EXPECTED TO WARM MUCH ABOVE FREEZING. GOING WITH AROUND AN INCH OF SNOW NEAR THE BUFFALO RIDGE.
309 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL KEEP OUR WEATHER QUIET BUT CHILLY TONIGHT THROUGH TUESDAY. WARMER AND WETTER WEATHER WILL ARRIVE BY THE MIDDLE OF THE WEEK. JUST AMAZING WHEN YOU CONSIDER NOT ONLY ITS MID MARCH BUT WE HAVE A HIGH SUN ANGLE AND FULL SUNSHINE! HIGH PRESSURE LOCATED NORTH OF LAKE HURON WILL BUILD SOUTH OVER THE AREA TONIGHT. HIGH PRESSURE AND THE CORE OF THE COLD AIR WILL SLIDE EASTWARD TUESDAY.
146 PM CDT Mon Mar 23 2015 Will have a flat ridge over the area the next several days bringing mild wx to the region with mostly sunny days and clear nights through midweek. This will give way to a mid level trough swinging down across the Rockies as an upper ridge builds across the West Coast.
339 PM CDT MON MAR 23 2015 OVERNIGHT FORECAST BECOMING COMPLICATED BY STRATUS DEVELOPMENT TODAY AND MUCH COOLER HIGHS THAN ANTICIPATED. THERE IS STILL A RISK FOR SOME LIGHT FREEZING RAIN ON THE NORTHERN EDGE OF THE PRECIPITATION SHIELD AND OVER SOUTHEAST SECTIONS AS THE PRECIPITATION COMMENCES. THE RELATIVELY DRY AIR AND THE EXPECTATION THAT OVERNIGHT LOWS OVER THOSE AREAS WILL LIKELY BE AT OR JUST BELOW THE FREEZING MARK BY SUNRISE. LOWS WILL RANGE FROM THE 20S NORTHEAST TO THE LOWER TO MID 30S OVER THE SOUTHWEST.
THE REGION IS CURRENTLY SITUATED BETWEEN AN EXITING LOW PRESSURE SYSTEM OVER IOWA. AND AN APPROACHING LOW PRESSURE OVER SOUTHERN SASKATCHEWAN. HIRES MODELS SUGGEST THE LOW CLOUDS WILL REMAIN OVER THE AREA THROUGH MID MORNING BEFORE DISSIPATING. THE LOW PRESSURE SYSTEM OVER SOUTHERN SASKATCHEWAN WILL TRACK NORTHEAST OF THE REGION TODAY. THIS SYSTEM WILL BRING WARMER TEMPERATURES INTO THE WESTERN DAKOTAS WHERE HIGHS SHOULD CLIMB INTO THE 50S AND 60S. ALONG WITH COOLER TEMPERATURES ALOFT SHOULD RESULT IN HIGHS ONLY IN THE UPPER 30S TO THE LOWER 40S AT BEST. MODELS AGREE WELL WITH AN UPPER LEVEL TROUGH OF LOW PRESSURE SPREADING WARM AIR ADVECTION SHOWERS OVER THE WESTERN CWA TONIGHT.
For the rest of the area, expect little more than some clouds and slightly cooler temps. High pressure builds back in for Tuesday night into the end of the week.
238 PM MDT MON MAR 23 2015 THE UPPER TROUGH TO THE NORTHWEST OF COLORADO WILL MAKE ITS WAY ACROSS NORTHERN COLORADO TONIGHT THROUGH TUESDAY MORNING. STRONG NORTHWEST WINDS DEVELOP BEHIND THE COLD FRONT TUESDAY MORNING. COOLER ON TUESDAY BUT TEMPERATURES STILL RELATIVELY MILD ACROSS THE NORTHEAST PLAINS.
ISSUED BY NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC 401 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL EXTEND OVER THE AREA THROUGH TUESDAY WITH UPPER LEVEL DISTURBANCES MOVING ACROSS FROM THE WEST. LOW PRESSURE TRACKS TOWARD THE GREAT LAKES TUESDAY NIGHT.
THE DEEPEST LOW LEVEL MOISTURE RESIDES SOUTH AND MGM/TOI WILL THEREFORE HAVE THE LOWEST CEILINGS. 75 /ISSUED 409 AM CDT MON MAR 23 2015/ MID LEVEL TROUGH AXIS REMAINS JUST TO OUR NORTHWEST THIS MORNING. HIGH PRESSURE WILL BUILD TOWARD THE AREA FROM THE WEST THIS AFTERNOON AND TONIGHT. BUT LOW LEVEL FLOW WILL BE DOMINATED BY STRONGER HIGH PRESSURE OVER THE NORTHEAST CONUS AND WEDGING ACROSS GA AND NORTHEAST AL. A COOL EASTERLY FLOW SHOULD PREVENT FOG DEVELOPMENT TONIGHT AND BRING OVERNIGHT LOWS DOWN INTO THE LOWER 40S ACROSS THE FAR NORTHEAST. A COUPLE DAYS OF DRY CONDITIONS ARE EXPECTED AS HIGH PRESSURE REMAINS IN PLACE ACROSS THE NORTHEAST CONUS GIVING CENTRAL ALABAMA A EAST TO SOUTHEAST WIND AND MID LEVEL RIDGING KEEPS THE STORM TRACK TO OUR NORTH.
An upper level low pressure system will push a cold front through central Montana this afternoon and evening bringing a mix of rain or mixed rain and snow to the area. Conditions will be deteriorating early in the period with gusty winds expected near and behind the cold front.
UPPER TROUGH NOW OVER GA-FL PANHANDLE WILL PUSH ACROSS THE AREA THIS EVENING WITH FRONT SHIFTING SE OF THE AREA. HIGH PRESSURE WILL BUILD INTO THE AREA FROM THE NORTH TONIGHT WITH THE NE SURGE SPREADING LOW CLOUDS AND DRIZZLE ACROSS THE AREA. MODELS SHOW INVERTED TROUGH NEAR THE COASTAL AREAS WHICH WILL LEAD TO A SLIGHT CHANCE OF SHOWERS. MODELS HAVE TRENDED WARMER WITH HIGHS SO NUDGED THEM UP BUT NOT AS MUCH AS LATEST GUIDANCE DUE TO EXPECTATION OF A SOMEWHAT SLOW DISSIPATION OF LOW CLOUDS IN THE AREA.
Given the high potential for travel impacts overnight and Tuesday morning we have issued a full suite of Winter Weather Advisories and the details of those can be viewed on our website at www.
120 PM PDT MON MAR 23 2015 BEHIND TODAYS TROUGH A WARMING TREND AND GUSTY NORTH WINDS ARE EXPECTED FOR PARTS OF THE AREA THROUGH MID WEEK. WELL ABOVE NORMAL TEMPERATURES ARE FORECAST FOR THE END OF THE WEEK AND WEEKEND DUE TO SANTA ANA WINDS AND HIGH PRESSURE BUILDING ALOFT. LOOKS VERY SIMILAR TO THE LAST HEAT WAVE WE HAD WITH HIGHS IN THE HIGH 80S TO MID 90S.
By the end of the week strong ridging will build over the region bringing a gradual warming and drying trend. This cold front will exit eastern WA in the next hour or so but will continue to bring rain showers to the panhandle through this afternoon. /Kelch 18Z TAFS: A cold front will cross the Idaho panhandle early this afternoon. After the morning cold front departs conditions should remain generally VFR outside of shower cores.
THIS FEATURE WILL REMAIN WELL NORTH OF OUR REGION BUT IT WILL HELP TO DRAG A COLD FRONT DOWN INTO THE SOUTHERN PLAINS. A LONGWAVE TROUGH WILL MOVE OUT OF THE FOUR CORNERS REGION AND INTO THE CENTRAL/SOUTHERN PLAINS FOR WED/WED NIGHT WITH INCREASING CHANCES OF SHOWERS/THUNDERSTORMS ACROSS OUR REGION LATE WED NIGHT/THU ALONG AND AHEAD OF ANOTHER COLD FRONT.
For northern and northeastern Missouri this change was more significant as lower clouds are streaming into that area, wrapping around the low-level circulation center. For tonight, strong and broad moist isentropic ascent will overspread the low level frontal boundary resulting in widespread showers and thunderstorms forming over eastern Kansas and then spreading east-northeastward into northeastern Kansas and northwestern into northern Missouri. Models have a decent agreement on the track of the low, moving it from west central Missouri, right near the Kansas City area, into northeastern Missouri, around the Kirksville area.
A WEAK COLD FRONT OR SFC TROF OF LOW PRESSURE WILL MEANDER AROUND THE REGION EARLY THIS AFTERNOON BEFORE DISSIPATING. ANOTHER WEAK COLD FRONT WILL MOVE ACROSS THE TAF SITES AROUND SUNRISE TUESDAY. A COLD FRONT WHICH HAS MOVED SOUTH OF KDHT AND KGUY IS EXPECTED TO STALL OUT SOMEWHERE NEAR KAMA THIS MORNING. BEFORE RETREATING NORTHWARD AS A WARM FRONT THIS AFTERNOON. VERY WARM CONDITIONS EXPECTED TODAY IN SPITE OF WEAK COLD FRONT MAKING ITS WAY INTO NORTHERN SECTIONS THIS MORNING. STRONGER COLD FRONT ON TUESDAY WILL RESULT IN SLIGHTLY COOLER CONDITIONS THAN THOSE OF TODAY.
307 PM EDT MON MAR 23 2015 HIGH PRESSURE WILL BUILD IN FROM THE WEST THROUGH TUESDAY.
331 PM EDT MON MAR 23 2015 HIGH PRESSURE OVER LAKE HURON WILL MOVE OFF THE EAST COAST TUESDAY NIGHT.
SOUTH TO SW WINDS OVERNIGHT MAINLY AOB 12 KTS /SLIGHTLY STRONGER THRU THE EVENING KCDS/ TO VEER TO NW TUESDAY MORNING BEHIND A WEAK COLD FRONT. TEMPS WILL BE WARM ON WED AHEAD OF THE APPROACHING COLD FRONT. THURS WILL BE MUCH COOLER THANKS TO CLOUD COVER AND CONTINUED CAA AT THE SURFACE WITH HIGHS AVERAGING IN THE MID TO UPPER 50S. TEMPS THURS MORNING ARE EXPECTED TO REMAIN ABOVE FREEZING FOR MUCH OF THE AREA WITH THE EXCEPTION OF THE SOUTHWESTERN TX PANHANDLE WHERE TEMPS MAY DIP SLIGHTLY BELOW FREEZING.
156 PM EDT MON MAR 23 2015 A LOW PRESSURE OVER NORTHERN FLORIDA WILL MOVE EAST ALONG A STALLED FRONTAL BOUNDARY AS HIGH PRESSURE CENTERED OVER EASTERN CANADA RIDGES INTO THE CAROLINAS.
324 PM CDT MON MAR 23 2015 A WEAKLY AMPLIFIED UPPER FLOW PATTERN PERSISTS ACROSS MUCH OF THE CONUS WITH WEAK RIDGING OVER THE PLAINS AND SE, AND WEAK MID-LEVEL TROUGH ON EITHER SIDE OF THE RIDGE. THIS MAY RESULT IN COOLER DAYTIME HIGHS OVER NE AL/S MIDDLE TN ON TUESDAY BUT HIGHS SHOULD STILL REGISTER IN THE UPPER 60S TO LOW 70S (HIGHER OVER NW AL).
STRENGTHENING HIGH PRESSURE ALOFT WILL THEN BRING EVEN WARMER TEMPERATURES. THEN AN UPPER RIDGE WILL AMPLIFY ADJACENT THE WEST COAST WED. THE UPPER RIDGE WILL CONTINUE TO BUILD OVER THE GREAT BASIN/PACIFIC NORTHWEST THUR. CLEAR SKIES SHOULD BE THE RULE FRI-SAT AS THE UPPER HIGH EXPANDS EWD OVER THE SWRN CONUS. THE GFS DEPICTED DRY NWLY FLOW ALOFT WITH AN UPPER RIDGE AXIS NEAR THE WEST COAST. THIS UPPER LOW IS THEN PROGGED TO MOVE SEWD ACROSS SE ARIZONA BY MON EVENING. EXPECT EVEN WARMER TEMPS FRI-SAT FOLLOWED BY NO SIGNIFICANT CHANGE IN HIGH TEMPS SUN. SOMEWHAT COOLER TEMPS ARE FORECAST TO OCCUR MON. THEN BUILDING HIGH PRESSURE ALOFT WILL PROVIDE EVEN WARMER TEMPERATURES THIS WEEKEND.
A COLD FRONT PUSHES INTO THE REGION LATE TUESDAY MORNING BRINGING WITH IT LITTLE MORE THAN A WIND SHIFT. /ISSUED 423 AM CDT MON MAR 23 2015/ SHORT WAVE TROUGHING MOVING ACROSS THE ROCKIES TODAY WILL BEEF UP SURFACE LEE TROUGHING.
HIGH PRESSURE OVER THE AREA WITH LIGHT NORTHEAST WINDS OR VARIABLE.
CLEAR SKIES AND LIGHT WINDS NOTED ACROSS THE AREA TODAY AS HIGH PRESSURE REMAINS IN PLACE ACROSS THE STATE.
MOISTURE WRAPPING AROUND LOW PRESSURE ADVANCING TO THE EAST OF THE REGION WILL START ALL TERMINALS UNDER MVFR CLOUDINESS THIS MORNING.
1245 PM CDT MON MAR 23 2015 HIGH PRESSURE CENTERED OVER NORTHEAST TEXAS WILL SUPPRESS CLOUDS TODAY AND ALL TERMINALS WILL BE VFR THROUGH THIS PERIOD.
424 PM EDT MON MAR 23 2015 LOW PRESSURE WILL BE SHIFTING FARTHER OFF THE SOUTHEAST COAST AS HIGH PRESSURE RIDGES SOUTHWARD AND INTO THE FORECAST AREA TONIGHT.
WE WILL BEGIN THE PERIOD IN THE WARM SECTOR WITH LOW PRESSURE TRACKING NE ACROSS THE GREAT LAKES.
Zonal flow aloft will induce lee troughing and stronger winds today, With mostly sunny skies, temperatures will warm in the mid 80s over much of the region.
144 PM EDT TUE MAR 24 2015 HIGH PRESSURE WILL BUILD IN TODAY. A WARM FRONT WILL BRING THE CHANCE FOR SHOWERS LATE TONIGHT AND WEDNESDAY. SUBSIDENCE IS EXPECTED TO INCREASE THROUGH THE AFTERNOON AS HIGH PRESSURE BUILDS IN BEHIND A WEAK EXITING UPPER TROUGH. THIS SHOULD GRADUALLY DECREASE THE LOWER LEVEL STRATOCU. WARM AIR ADVECTION WILL CONTINUE TONIGHT WITH RIDGE BUILDING IN FROM THE WEST. A SURFACE WARM FRONT WILL APPROACH FROM THE SOUTHWEST LATE TONIGHT. SHOWERS WILL BE MORE SPOTTY OR SCATTERED IN NATURE AS THE WARM FRONT WILL BE RUNNING UNDERNEATH THE AFOREMENTIONED RIDGE. A DRIER ATMOSPHERE WILL FILL IN BEHIND THE WARM FRONT. STILL SEEING SOME TIMING AND LOCATION DIFFERENCES BETWEEN MODELS ON WHERE THE NEXT SURFACE WAVE DEVELOPS ALONG THE COLD FRONT AND WHERE IT WILL EVENTUALLY GO.
A STRONG COLD FRONT WILL MOVE ACROSS THE OK AND TX PNHDLS WEDNESDAY.
TEMPS HAVE WARMED INTO THE LOWER TO MID 70S AREA-WIDE. NO SIGNIFICANT CHGS CONCERNING THE NEXT COLD FRONT WHICH SHOULD ARRIVE ACROSS NW PORTIONS OF THE AREA THURS MORNING AND PUSH THROUGH THE COASTAL WATERS BY LATE THU AFT.
625 PM EDT TUE MAR 24 2015 A WARM FRONT WILL INITIATE THE CHANCE FOR RAIN LATE TONIGHT AND WEDNESDAY.
442 PM EDT TUE MAR 24 2015 LOW PRESSURE TRACKS TOWARD THE GREAT LAKES TONIGHT. LIFTING A WARM FRONT NORTH OF THE AREA ON WEDNESDAY.
321 PM EDT TUE MAR 24 2015 HIGH PRESSURE IS CENTERED ACROSS FAR EASTERN ONTARIO PROVINCE. THE RIDGE STRETCHES DOWN ALONG THE EASTERN SEABOARD INTO THE EASTERN CWFA. THE LOW LEVEL MOISTURE WILL INCREASE OVERNIGHT ACROSS MUCH OF THE CWFA AND LOW LEVEL CLOUDS WILL SETTLE OVER MUCH OF THE REGION. THE WEDGE SHOULD START TO ERODE OVERNIGHT WEDNESDAY AS A COLD FRONT APPROACHES FROM THE NW.
254 PM EDT TUE MAR 24 2015 A WARM FRONT WILL BRING THE CHANCE FOR SHOWERS LATE TONIGHT AND WEDNESDAY.
355 PM EDT TUE MAR 24 2015 HIGH PRESSURE WILL SHIFT OFFSHORE ON WEDNESDAY.
At the surface, a weak cold front is moving into our northern zones this afternoon. The large trough currently in the northwestern U. will dig farther south into the south plains tomorrow as a strong northerly jet streak develops on the western side of the trough. This will send a cold front south toward the area tomorrow.
NOTE THE NORTH WIND AND SLIGHTLY COOLER TEMPS AT CKV. SOUTH WINDS WERE PUSHING TEMPS INTO THE LOWER 70S FOR MOST LOCATIONS. A LOW PRESSURE SYSTEM FROM THE MID MS VALLEY WILL MOVE NORTHEAST TO THE GREAT LAKES REGION. WILL LIFT NORTHEASTWARD WITH THE LOW PRESSURE.
115 PM PDT TUE MAR 24 2015 GUSTY WINDS AND WARMER TEMPERATURES ARE EXPECTED TODAY.
AND AS WEAK DISTURBANCES ASSOCIATED WITH UPPER LEVEL TROUGH SCT/BKN CI CEILINGS WILL EVENTUALLY BE REPLACED BY BKN AC CEILINGS AROUND 25/04Z.
Brief surface/upper ridging will produce dry conditions with high temperatures ranging from the upper 50s north to the upper 60s south of I-70.
WILL MAINTAIN POSSIBLE ISOLD SHOWERS AS LOW LEVEL TROUGH AND SUFFICIENT MAINLY LOW LEVEL MOISTURE WILL BE AVAILABLE. HIGHS SHOULD BE WARMER IN THE MID 70S TO AROUND 80.
608 PM EDT TUE MAR 24 2015 HIGH PRESSURE WILL SHIFT OFFSHORE ON WEDNESDAY.
325 PM EDT TUE MAR 24 2015 HIGH PRESSURE WILL CONTINUE TO RIDGE INTO THE FORECAST AREA FROM THE NORTH TONIGHT.
19Z SFC ANALYSIS SHOWS THE COLD FRONT HAS CLEARED CENTRAL OK AND SHOULD REACH THE RED RIVER VALLEY AROUND 3 TO 4 PM. STRONGER COLD FRONT WILL MOVE SOUTHWARD OFF THE CENTRAL PLAINS INTO N/NW OK THROUGH THE MORNING HOURS. STORMS WILL INITIALIZE ON THE COLD FRONT.
216 PM EDT TUE MAR 24 2015 A WARM FRONT WILL MOVE NORTH TOWARD THE OHIO RIVER TODAY. SHOWERS WILL BE LIKELY AND THUNDERSTORMS WILL BE POSSIBLE TONIGHT INTO WEDNESDAY WHEN THE WARM FRONT IS FORECAST TO MOVE NORTH ACROSS THE AREA.
THE BAND OF RAIN MAY LIFT NORTHEAST FAST ENOUGH MOVING INTO AREAS WHERE THE TEMPERATURE IS SLIGHTLY BELOW FREEZING ACROSS NORTHWEST IOWA INTO SOUTHWEST MINNESOTA. EXPECT ANY LATENT HEAT RELEASE IN THE FREEZING PROCESS TO HELP WARM THE ATMOSPHERE LEADING TO RELATIVELY SHORT PERIOD OF FREEZING RAIN BEFORE RAIN TAKES OVER. FORECAST SOUNDINGS WET BULB DOWN TO BELOW FREEZING WITH ANY AIR ABOVE FREEZING BEING CONTAINED RIGHT NEAR THE SURFACE. THIS IS AHEAD OF THE COLD FRONT ASSOCIATED WITH THE WAVE TO THE NORTH. AS THE COLD FRONT SURGES SOUTH ACROSS THE AREA WEDNESDAY MORNING.
THE COLD FRONT ARRIVES LATE TONIGHT AND NORTHWEST WINDS QUICKLY BECOME ESTABLISHED AT THE SURFACE. THAT WILL OF COURSE BE WARMER FOR MOST OF THE AREA BUT COOLER SOUTHWEST.
218 PM EDT TUE MAR 24 2015 HIGH PRESSURE WILL MOVE EAST OF THE AREA LATER TODAY AND OVERNIGHT.
/ISSUED 929 AM EDT TUE MAR 24 2015/ HIGH PRESSURE HAS WEDGED DOWN FROM THE NORTHEAST THIS MORNING. /ISSUED 411 AM EDT TUE MAR 24 2015/ WEDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD INTO THE AREA TODAY AND WEDNESDAY. AFTERNOON HIGHS TODAY AND WEDNESDAY WILL REACH THE LOW TO MID 70S.
USING THESE TEMPERATURES AS A GUIDE TODAY FOR HIGHS TODAY THE CURRENT FORECAST WILL LOOKS ON TRACK WITH HIGHS MAINLY IN THE LOW TO MID 70S. AS THIS HIGH CLOUDS INCREASE ACROSS WESTERN KANSAS A COLD FRONT WILL BE MOVING SOUTH OUT OF NEBRASKA AND INTO WESTERN KANSAS BY EARLY WEDNESDAY MORNING. AT THIS TIME GIVEN THE LOCATION OF THE FRONT EARLY WEDNESDAY MORNING AND THE EXPECTED CLOUD COVER WILL TREND TOWARDS THE WARMER GUIDANCE FOR OVERNIGHT LOWS, ESPECIALLY IN SOUTH CENTRAL KANSAS.
NW AND NNW ASSOCIATED WITH A COLD FRONT MOVING OUT OF KS. /ISSUED 430 AM CDT TUE MAR 24 2015/ NORTHWEST WINDS WILL BRIEFLY INCREASE BEHIND A COLD FRONT INITIALLY ACROSS NORTHWESTERN OK THIS MORNING. THE WEAK COLD FRONT WILL STALL ACROSS SE OK. HIGHER SEVERE STORM CHANCES ARE EXPECTED LATE WED AFTERNOON THROUGH WED NIGHT MAINLY ALONG AND SOUTH OF I44 AS A SIGNFICANT COLD FRONT DIVES SOUTH ACROSS CENTRAL OK.
SOME RESIDUAL SNOW WITH PERHAPS ANOTHER HALF INCH ACCUMULATION EXPECTED THROUGH MIDNIGHT IN THE EASTERN HIGHLANDS AS HIGH PRESSURE BEGINS TO TAKE SHAPE NEAR THE COAST.
TEMPERATURES HAVE RISEN INTO THE LOWER 70S IN MANY AREAS AS OF 3 PM EDT. SOME BREEZY/GUSTY SOUTHEAST GRADIENT WINDS WILL ALSO BE POSSIBLE AT TIMES OVER THE HIGHER TERRAIN OF THE EAST TENNESSEE MOUNTAINS AND THEIR SURROUNDING FOOTHILLS. WILL HELP TO PUSH HIGHS INTO THE LOW TO MID 70S ONCE AGAIN.
A STRONG RIDGE OF HIGH PRESSURE WILL BUILD LATER THIS WEEK WITH POSSIBLE RECORD HIGH TEMPERATURES. WITH SNOW SHOWERS DECREASING ALONG WITH TEMPERATURES ABOVE FREEZING AT THIS TIME.
EXPECT 850 MB TEMPERATURES BY THIS AFTERNOON TO BE A BIT WARMER THAN YESTERDAY.
206 PM EDT TUE MAR 24 2015 WARM FRONT LIFTS NORTH TONIGHT.
RAIN (SHOWERS AND POSSIBLE THUNDERSTORMS) COME BACK INTO THE FORECAST BEGINNING LATE WEDNESDAY NIGHT UP NORTH AS A COLD FRONT MOVES INTO THE AREA.
DEPARTING UPPER WAVE AND ASSOCIATED SFC CYCLONE/TROUGH WILL SUPPORT RAIN OVER THE NW HALF OF THE FA THIS MORNING WITH DRYING THIS AFTERNOON MOST PLACES. BACKSIDE COLD FRONT WILL SHIFT SE INTO THE FA THIS EVENING. WITH MUCH COOLER CONDS ON TRACK FOR WED AS STRONGER NEGATIVE HEIGHT ANOMALY SHIFTS SE INTO THE EASTERN HALF OF THE CONUS. SFC COLD FRONT WILL SHIFT INTO THE FA.
339 PM CDT TUE MAR 24 2015 DOUBLE-BARRELED LOW PRESSURE TO AFFECT THE NORTHLAND THROUGH WEDNESDAY NIGHT WITH PRECIPITATION TYPE THE MAIN CONCERN. BOTH LOWS WILL MOVE EAST WITH THE UPPER TROF. PRECIPITATION HAS BROKEN OUT ALONG THE BAROCLINIC ZONE BETWEEN THE LOW WITH RAIN TO THE SOUTH OVER MN AND IOWA AND SNOW OVER THE OTHER IN NORTH DAKOTA.
Winter weather advisories remain in place for portions of the higher terrain/mountain passes through midnight. As the low pressure system exits the region late tonight, a weak weather system will approach the area around mid day Wednesday.
A DISTURBANCE AND LOW PRESSURE SYSTEM PASSING BY WELL TO THE NORTH THROUGH TONIGHT WILL BE INSTIGATING SOME POWERFUL STORMS UP IN THE PLAINS AND MID MS VALLEY BUT THE LOWER MS VALLEY WILL REMAIN CAPPED TO CONVECTION. LOW LEVEL GULF MOISTURE INFLUX WILL BE STRENGTHENED A BIT IN RESPONSE TO THIS LOW PRESSURE PASSING TO OUR NORTH AND THIS SHOULD ONCE AGAIN HELP IN LATE NIGHT LOW CLOUD AND PATCHY FOG FORMATION. MODEL CONSENSUS SUGGESTS MOISTURE TRANSPORT COULD BE ENOUGH ACROSS AT LEAST SOUTHEAST MS TO PROMOTE SOME ISOLATED SHOWERS OR PATCHY DRIZZLE ALONG WITH THE LOW CLOUDS. TOMORROW SHOULD BE EVEN WARMER.
WILL SEE A SLOW DECREASE IN WIND SPEEDS TONIGHT BUT GRADIENT ASSOCIATED WITH THE LOW WILL STILL KEEP THEM SOMEWHAT BREEZY. CWA LOOKS TO BE DRY BUT HAVE MAINTAINED JUST A SLIGHT CHANCE POP ALONG THE NORTHEAST FRINGE TO ACCOUNT FOR ANY WRAP AROUND MOISTURE FROM THE LOW.
LOWERED THE HIGH TEMPS AND TRENDS IN THESE AREAS. AS MID LEVEL RIDGING BUILDS ACROSS THE SOUTHEAST. TEMPERATURES WILL WARM INTO THE LOW TO MID 70S TODAY.
