322 PM CDT SUN SEP 13 2015 AN AREA OF LOW PRESSURE AND SURFACE COLD FRONT WILL SLIDE ACROSS THE REGION TONIGHT. DEPENDING ON THE EXTENT OF CLOUD COVER AND HOW FAR SOUTH THE COLD FRONT TRACKS. HIGHS ON MONDAY COULD BE COOLER THAN EXPECTED. MAINLY IN THE NORTHEASTERN PORTION OF THE CWA WHERE LLM TEMPS ARE COOLER ON MOST MODELS.
A DRY AND STABLE RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE AREA THROUGH THE FORECAST PERIOD.
UPPER FLOW HAS BEEN FAIRLY ZONAL BUT BY MONDAY SHOULD BECOME MORE SOUTHWESTERLY AS AN UPPER TROUGH DIGS INTO THE WESTERN CONUS. THE SREF PROBABILITIES SHOW THAT MANY MODELS ARE TRYING TO BREAK OUT SOME FOG ALONG THE TROUGH AXIS IN OUR EAST CENTRAL COUNTIES. TEMPS WILL BE A BIT COOLER THAN TODAY. WITH A WARM FRONT LIFTING NORTH ACROSS THE CWA OVERNIGHT.
356 PM EDT SUN SEP 13 2015 HIGH PRESSURE WILL EXPAND ACROSS THE SOUTHERN GREAT LAKES TONIGHT.
340 PM CDT SUN SEP 13 2015 ISSUED AT 330 CDT SUN SEP 13 2015 BROAD UPPER LEVEL RIDGE ACROSS THE SOUTHWEST CONUS INTO THE SOUTHERN PLAINS. MEANWHILE A TROUGH IS EXITING THE GREAT LAKES AND PUSH TOWARDS NEW ENGLAND. AT THE SURFACE A TROUGH/DRY LINE LIES ACROSS THE WESTERN HIGH PLAINS. THERMAL RIDGE EXPANDED ACROSS THE AREA TODAY WITH TEMPS AROUND 80 ACROSS THE FAR NORTHEAST ZONES TO THE MID AND UPPER 90S ACROSS THE FAR SOUTHWEST. THIS WILL ALSO SEE SOME ASSISTANCE BY THE LOW LEVEL JET FOR A SMALL POCKET OF INSTABILITY AND A SLIGHT CHANCE FOR STORMS WARRANTED. TOMORROW THE THERMAL RIDGE BUILDS ACROSS MUCH OF THE AREA WITH WIDESPREAD 90S EXPECTED. THE LOW DEW POINTS WILL ALLOW FOR A SURGE IN TEMPS WITH HIGHS TOPPING OUT IN THE MID TO UPPER 90S.
230 PM EDT SUN SEP 13 2015 CANADIAN HIGH PRESSURE WILL BUILD INTO CENTRAL NC THROUGH MONDAY THEN REMAIN OVERHEAD THROUGH THE REMAINDER OF THE WORK WEEK. STRONG VORT CENTER ROUNDING THE BASE OF THE UPPER LEVEL TROUGH OVER CENTRAL NC MAY CAUSE A SCATTERED CU FIELD TO DEVELOP IN VICINITY OF THE VIRGINIA BORDER COUNTIES. MAX TEMPS THIS AFTERNOON STILL ON TARGET FOR THE LOW-MID 70S NW TO THE MID-UPPER 70S SE. BENEATH STRONG HEIGHT RISES ALOFT BEHIND THE LIFTING UPPER TROUGH.
146 PM EDT SUN SEP 13 2015 COOL AND DRY HIGH PRESSURE BUILDING INTO THE REGION THROUGH MONDAY WILL SETTLE OVER THE MID ATLANTIC BY MIDWEEK.
300 PM EDT SUN SEP 13 2015 A COLD FRONT HAS MOVED INTO CENTRAL FLORIDA EARLY THIS AFTN. HIGHS MONDAY WILL BE A COUPLE OF DEGREES WARMER THAN SUNDAY BUT STILL A COUPLE DEGREES BELOW NORMAL. THE AIR MASS QUICKLY MODIFIES MONDAY NIGHT AS HIGH PRESSURE BUILDS NORTH OF THE AREA AND THE ONSHORE FLOW INCREASES. A WEAK COASTAL TROUGH DEVELOPS OFFSHORE WHICH WILL BRING IN A FEW COASTAL SHOWERS MONDAY NIGHT. MIN TEMPS MUCH WARMER MONDAY NIGHT ESPECIALLY NEAR THE COAST. THE ADDED LIFT FROM THE UPPER LOW COUPLED WITH A MOIST AND UNSTABLE EASTERLY FLOW WILL LEAD TO SCATTERED TO NUMEROUS SHOWERS AND STORMS MOST AREAS.
RED FLAG WARNING IN OUR FAR WESTERN ZONES WORKING OUT THIS AFTERNOON AS DOWNSLOPE WINDS MIXED OUT WITH WINDS 20 MPH GUSTING TO OVER 35 MPH AT LIVINGSTON AND HUMIDITY IN THE LOWER TEENS AS OF 2 PM. WE WILL SEE A COOL DOWN OF 5 TO 10 DEGREES FOR MONDAY DUE TO RELATED DECREASING HEIGHTS AS RIDGE IS WEAKENED. WE EXPECT COOLER CONDITIONS FOR MONDAY AS TROUGH DROPS TO THE WEST COAST.
WITH LOWS DROPPING INTO THE LOW TO MID 40S INLAND OF LAKE MICHIGAN. HIGHS WILL BE IN THE LOW TO MID 70S. OTRWS HIGH PRESSURE RIDGE MOVG ACROSS THE AREA WILL PROVIDE FAIR WX IN OUR AREA DURING THE SHORT TERM PERIOD. RIDGE AXIS WILL MOVE EAST OF THE AREA TONIGHT ALLOWING FOR AN INCREASING SWLY GRADIENT BUT THERE STILL SHOULD BE AT LEAST A PERIOD OF DECOUPLING AND RATHER STRONG RADIATIONAL COOLING OVER MOST OF THE AREA. THE CHALLENGES THIS PERIOD INCLUDE THE TIMING OF SHORT WAVE TROFS AND ASSOCIATED WEATHER LATE THIS WEEK.
IT SHOULD BE MAINLY SPRINKLES AS THE LOWER LEVELS REMAIN PRETTY DRY. AND THE TROUGH TO OUR WEST WON'T ARRIVE UNTIL AFTER 00Z. COLD ADVECTION KICKS INTO FULL GEAR BEHIND THE DEPARTING COLD FRONT. AS A COLD FRONT SLIPS ACROSS THE AREA TONIGHT. THE LOWER CIGS MAY LEAD TO SOME PATCHY DRIZZLE AS WELL BY MONDAY MORNING.
639 AM EDT SUN MAR 27 2016 A NEARLY STATIONARY FRONT ACROSS THE NORTHERN MIDLANDS WILL LIFT NORTH AS A WARM FRONT THIS AFTERNOON. WEAK AREAS OF LOW PRESSURE RESULTING IN NUMEROUS TO WIDESPREAD SHOWERS. ANOTHER COLD FRONT WILL MOVE ACROSS THE REGION BY EARLY MONDAY AFTERNOON.
A COLD FRONT WILL BRING SHOWERS BACK TO THE AREA TONIGHT INTO EARLY MONDAY. UNSEASONABLE WARMTH AND DRY WEATHER WILL END LATE TONIGHT WITH THE ARRIVAL OF A COLD FRONT. STILL SOME DIFFERENCES ACROSS MODEL GUIDANCE ON THE TIMING OF THE COLD FRONT TONIGHT. HIGH TEMPERATURES LOOK TO BE SOME 20-25 DEGREES COOLER THAN TODAY. PASSAGE OF H500 TROUGH AXIS WILL HELP TO DECREASE SHRA COVERAGE SLOWLY THROUGH THE DAY. BUT CONTINUED NW FLOW AND COLD ADVECTION INTO THE EVENING WILL KEEP SOME ISOLATED ACTIVITY GOING IN AT LEAST THE RIDGES.
330 AM CDT SUN MAR 27 2016 EARLY MORNING TEMPERATURES ACROSS THE MIDSOUTH ARE MOSTLY IN THE LOW TO MIDDLE 50S. HOWEVER DEW POINTS MAY CREEP INTO THE MIDDLE 60S JUST AHEAD OF THE COLD FRONT. WINDS WILL SHIFT FROM THE NORTHWEST BRINGING A COOLER.
AN UPPER LEVEL TROUGH OVER THE EASTERN PACIFIC CONTINUES TO DIG SOUTHEAST TOWARDS THE PACIFIC NORTHWEST THIS EVENING. THIS TROUGH WILL PUSH A COLD FRONT ACROSS THE REGION OVERNIGHT INTO MID MORNING SUNDAY. THE UPPER TROUGH WILL MOVE OVER THE REGION BY SUNDAY AFTERNOON, CAUSING ENOUGH INSTABILITY FOR ISOLATED TO SCATTERED SHOWERS AREAWIDE. COLD AIR WILL EXIT THE AREA AS A LOW PRESSURE SYSTEM MOVES TO THE SOUTHEAST. HIGH PRESSURE WILL BUILD OVER THE AREA FOR WHAT LOOKS TO BE A SEVERAL DAY BREAK IN PRECIPITATION TO THE PACIFIC NORTHWEST.
KEPT WINDS ELEVATED BEHIND THE FRONT THROUGH AT LEAST 03Z MONDAY AS A SECOND PUSH OF HIGH PRESSURE MOVES IN.
459 AM MDT SUN MAR 27 2016 UPPER RIDGE TRANSLATES OVER THE REGION TODAY RESULTING IN A DRY DAY ACROSS SOUTHERN COLORADO. SNOW COVER ALONG THE I-25 CORRIDOR MAY HOLD TEMPERATURES DOWN IN THE 40S FOR THE PALMER AND RATON RIDGES. SHOULD STILL SEE HIGHS IN THE LOWER 40S. FLOW ALOFT TRANSITIONS TO SOUTHWESTERLY AHEAD OF THE NEXT UPPER LOW MOVING INTO THE WESTERN U. LEE TROFFING AND WESTERLY DRAINAGE WINDS SHOULD HELP KEEP TEMPERATURES WARMER THAN THOSE OF THIS MORNING FOR MOST AREAS.

MODELS IN GOOD AGREEMENT IN NEAR TERM BUILDING RIDGE INTO THE NORTHERN PLAINS BEHIND UPPER TROUGH MOVING EAST INTO THE MISSISSIPPI VALLEY TODAY.
425 AM EDT SUN MAR 27 2016 HIGH PRESSURE OVERHEAD WILL RESULT IN MOSTLY CLEAR SKIES AND MAXIMUM TEMPERATURES GENERALLY RANGING FROM THE MID 40S TO UPPER 50S THIS EASTER SUNDAY. LOW PRESSURE AND AN UPPER LEVEL DISTURBANCE APPROACHING FROM THE OHIO VALLEY WILL BRING INCREASING CLOUDS LATE SUNDAY NIGHT.
THIS FRONT IS FORECAST MOVE NORTHWARD AS A WARM FRONT LATER TONIGHT AS NEXT WAVE MOVES NORTH OUT OF THE GULF. COLD FRONT WILL MOVE THROUGH THE REMAINDER OF THE FORECAST AREA EARLY ON MONDAY AND STALL JUST TO THE SOUTH OF THE FORECAST AREA.
THE COOL SPOT WAS MANITOWOC AT 32 WHERE THE LOW CLOUDS HAVE NOT ARRIVED. COMPLEX FORECAST CONTINUES TODAY AS LOW PRESSURE MOVES ACROSS THE REGION. WITH A LITTLE SNOW POSSIBLE AT TIMES ACROSS VILAS COUNTY DUE TO THE HIGHER TERRAIN AND COLDER TEMPERATURES AT 850MB. AS THE LOW MOVES ACROSS THE STATE. HIGH PRESSURE BUILDS INTO THE REGION LATER TONIGHT.
HIGH PRESSURE CENTERED FAR NE OF FLORIDA EXTENDS INTO THE SOUTHERN HALF OF THE PENINSULA. MODELS ALSO CONTINUE TO SHOW A PERSISTENT MID/UPPER LEVEL RIDGE ACROSS SOUTH FLORIDA. AN APPROACHING COLD FRONT WILL BRING BACK INCREASING CHANCES OF SHOWERS AND THUNDERSTORMS LATE MON AND INTO TUE.
CLOUD COVER HAS INCREASED ALONG AND SOUTH OF THIS WARM FRONT OVER MOST OF MIDDLE TENNESSE. A HIGH PRESSURE SYSTEM WILL MOVE IN ON MONDAY AND DOMINATE THE WEATHER DURING THE FIRST HALF OF THE WORK WEEK.
DENSE FOG IS FORMING OVER THE LOWER TEXAS COASTAL WATERS AND THE LOWER RIO GRANDE VALLEY. HAVE DECIDED TO ISSUE A DENSE FOG ADVISORY WITH CONDITIONS FAVORING THE LOW CEILINGS CONTINUING TO LOWER TO THE SURFACE OR THE LIGHT SOUTHEAST WINDS PUSHING THE MARINE FOG INLAND THE REST OF THE OVERNIGHT PERIOD. THE HIGH RES MODEL ALSO SUGGEST THE FOG AND LOWER CLOUDS TO HANG ALONG THE COAST UNTIL THE FRONT PASSES SOME TIME SUNDAY AFTERNOON. SOME SLOW IMPROVEMENT IS ANTICIPATED SUNDAY MORNING HOWEVER NOT UNTIL A COLD FRONT OVER NORTHWEST TEXAS MOVES THROUGH THE REGION SUNDAY AFTERNOON WILL FLYING CONDITIONS IMPROVE TO VFR.
AT 3 AM THE COLD FRONT STRETCHED JUST NORTH OF A STEPHENVILLE TO SAN ANGELO LINE AND WAS SURGING QUICKLY SOUTH. THE COLD FRONT SHOULD REACH THE NORTHERN HILL COUNTRY AROUND 7 AM. COOLER TONIGHT WITH LOWS IN THE 40S NORTH AND LOW 50S SOUTH. DRY MONDAY WITH HIGHS IN THE LOW TO MID 70S.
CLOUDINESS AHEAD OF THE COLD FRONT HAS KEPT AREA TEMPS UP OVERNIGHT. MIDNIGHT-2AM TEMPS WERE 10 TO 15 DEGREES WARMER THAN 24 HRS AGO ACROSS MOST OF SE OREGON. COLD FRONT ACROSS CENTRAL OREGON EXTENDS NW INTO DEEP GULF OF AK LOW. THE LOW SHIFTS ACROSS THE SNAKE PLAIN TODAY. ADVANCING UPPER LOW WILL BRING COOLING ALOFT FOR SHOWERS THIS AFTERNOON. COLD UPPER TROUGH SHIFTS THROUGH IDAHO MONDAY SO HAVE CONTINUED A CHANCE OF MOSTLY SNOW SHOWERS FAVORING THE MOUNTAINS.
SOME SLOW IMPROVEMENT IS ANTICIPATED SUNDAY MORNING HOWEVER NOT UNTIL A COLD FRONT OVER NORTHWEST TEXAS MOVES THROUGH THE REGION SUNDAY AFTERNOON WILL FLYING CONDITIONS IMPROVE TO VFR.
315 AM CDT SUN MAR 27 2016 AN AREA OF LOW PRESSURE NEAR SE MINNESOTA. A SUBTLE COLD FRONT WILL MOVE INTO THE NW FORECAST AREA THIS EVENING AND STALL OVERNIGHT.

AND SOUTH SHORE MAY ONLY SEE HIGHS IN THE LOW TO MIDDLE 40S.
WITH A COLD FRONT PASSING THROUGH ON MONDAY. FAIR BUT COOLER WEATHER WILL RETURN FOR MID WEEK. REMAINDER OF CENTRAL PA WILL REMAIN CLEAR OVERNIGHT WITH MINS RANGING FROM THE LOWER 30S NORTH TO THE LOWER 40S SOUTH. HAVE KEPT MILD MINS TONIGHT IN THE SE AND COOLER THAN GUID MAXES ON SUNDAY IN THE FCST.
A COLD FRONT WILL BRING SHOWERS BACK TO THE AREA TONIGHT INTO EARLY MONDAY. UNSEASONABLE WARMTH AND DRY WEATHER WILL END LATER TONIGHT WITH THE ARRIVAL OF A COLD FRONT. STILL SOME DIFFERENCES ACROSS MODEL GUIDANCE ON THE TIMING OF THE COLD FRONT TONIGHT. HIGH TEMPERATURES LOOK TO BE SOME 20-25 DEGREES COOLER THAN TODAY. PASSAGE OF H500 TROUGH AXIS WILL HELP TO DECREASE SHRA COVERAGE SLOWLY THROUGH THE DAY. BUT CONTINUED NW FLOW AND COLD ADVECTION INTO THE EVENING WILL KEEP SOME ISOLATED ACTIVITY GOING IN AT LEAST THE RIDGES.
AFT THE LOW CLOUDS ERODE. UPR TROF APPROACHES THE MIDWEST ON THU PRODUCING SW FLOW ALOFT OVER THE NERN CONUS. THE UPR TROF AXIS GETS CLOSER ON FRI WITH SW FLOW ALOFT CONTINUING. COOLER AIR BEGINS TO FILTER IN ON SAT AS THE FIRST TROF AXIS EXITS. HIGH PRESSURE OVER SOUTHEASTERN CANADA SLOWLY MOVES OFFSHORE TODAY. COMPLEX LOW PRESSURE APPROACHES THE REGION TONIGHT.
HIGH RES SREF MAINTAINS LOW CLOUDS AND FOG ALONG THE COAST THROUGH THE MORNING OR EVEN AS LATE AS UNTIL THE COLD FRONT MOVES THROUGH MID AFTERNOON. EASTERN LOCALS MIGHT HAVE A MORE DIFFICULT TIME WARMING UP TO THE FORECAST MAXES ESPECIALLY IF THE LOWER CLOUDS AND FOG HANG OUT UNTIL THE FRONT MOVES THROUGH. A COOLER SHALLOW NORTHEAST FLOW BEHIND THE FRONT IS EXPECTED WITH WEAK ISENTROPIC LIFT OR OVERRUNNING SETTING UP OVERNIGHT INTO MONDAY. THE SHALLOW NATURE OF THE MOISTURE AND NO COASTAL TROUGH DEVELOPING WOULD RESULT IN MORE CLOUDS THAN RAIN OR DRIZZLE.

WITH A COLD FRONT PASSING THROUGH ON MONDAY. FAIR BUT COOLER WEATHER WILL RETURN FOR MID WEEK. AS LOW CIGS BACK WESTWARD THROUGH THE LOWER SUSQ RIVER VALLEY TOWARDS EASTERN PORTIONS OF THE SOUTH CENTRAL MOUNTAINS. MARITIME INFLUENCE WILL RESULT IN SUBDUED TEMPERATURE CURVES AS HIGHS EAST OF THE ALLEGHENIES WILL BE SOME 6 TO 10 DEGREES COOLER THAN THOSE WEST OF THE ALLEGHENY CREST. MOISTURE CONTINUES TO INCREASE TONIGHT AS PRIMARY LOW PRESSURE SYSTEM LIFTS ENE THROUGH THE OHIO VALLEY AND DIRECTS DEEPER MOISTURE INTO THE REGION OVERNIGHT. BOTH AREAS OF LOW PRESSURE WILL BRING A GOOD CHANCE OF SHOWERS BY LATE SUNDAY NIGHT WITH WIDESPREAD SHOWERS ON MONDAY.
142 AM EDT SUN MAR 27 2016 HIGH PRESSURE OVERHEAD WILL RESULT IN MOSTLY CLEAR SKIES AND AFTERNOON HIGHS GENERALLY IN THE MID 50S FOR VALLEY LOCATIONS THIS EASTER SUNDAY. LOW PRESSURE AND AN UPPER LEVEL DISTURBANCE APPROACHING FROM THE OHIO VALLEY RESULTS IN INCREASING CLOUDS LATE SUNDAY NIGHT FOLLOWED BY WIDESPREAD RAINFALL DURING THE DAYLIGHT HOURS ON MONDAY. SNOW SHOWERS ARE POSSIBLE AS THE LOW DEPARTS ACROSS NEW BRUNSWICK AND THE ST.
However, overall low lvl moisture/LCLs above 1500 ft should keep the tornado risk on the low side. Will also likely be some post-frontal rains in the cooler air behind the front, but drier air pushing in from the west should bring a quick end to the precip before midnight tonight. High pressure will then build east directly over the forecast area on Monday, bringing a return to sunshine, light winds and fairly mild afternoon temperatures up in the lower 60 degrees.
INTERMITTENT LIGHT PRECIPITATION CONTINUES ACROSS THE KEWEENAW AND PART OF THE WEST WITH A FEW WEAK UPPER IMPULSES EJECTING OUT OF UPPER TROUGH JUST TO THE WEST. WBZ HEIGHTS REMAIN LOW ENOUGH OVER THE KEWEENAW FOR MOST OF THE PRECIPITATION TO STILL BE IN THE FORM OF LIGHT SNOW IN THE KEWEENAW BUT WITH SURFACE TEMPERATURES JUST ABOVE FREEZING ACCUMULATIONS HAVE BEEN LIMITED. SOME SNOWFLAKES MAY MIX IN ACROSS THE HIGHER TERRAIN AREAS OF THE WEST WITH A MIX OF RAIN AND SNOW EXPECTED ACROSS THE KEWEENAW.
400 AM PDT SUN MAR 27 2016 DRY WEATHER WILL CONTINUE INTO TONIGHT UNDER WEAKENING HIGH PRESSURE.
326 AM CDT SUN MAR 27 2016 Early this morning an intense upper level trough was lifting northeast across northwest OK.

Cold front to bring snow and gusty winds to the Northern.
A CHANCE OF SHOWERS/T-STORMS WILL INCREASE OVER NE LOUISIANA AT KMLU AS A COLD FRONT SWEEPS ACROSS THE AREA AFTER 27/15Z. AHEAD OF AN UPPER TROUGH DIGGING THROUGH SRN CO INTO NM. THE 00Z NAM REMAINS IN GOOD AGREEMENT WITH ITS 18Z PREDECESSOR WITH DEEPENING MOISTURE ADVECTION SPREADING NE INTO THE LOWER TOLEDO BEND COUNTRY/CNTRL LA LATE. ISOLATED CONVECTION WILL REMAIN POSSIBLE ELSEWHERE AHEAD OF A COLD FRONT THAT WILL ENTER THE REGION SHORT AFTER 12Z SUNDAY.
BEST COVERAGE OF SHOWERS WILL BE AFTER 06Z AS A COLD FRONT MOVES ACROSS THE REGION.
THIS WILL CHANGE BY AROUND SUNRISE AS MOISTURE LEVELS INCREASE AHEAD OF AN APPROACHING COLD FRONT. THIS WILL CHANGE BY AROUND SUNRISE AS MOISTURE LEVELS INCREASE AHEAD OF AN APPROACHING COLD FRONT. NWLY WINDS WL USHER COOLER AND DRIER AIR INTO THE REGION. WINDS WL DIMINISH LATER SUN NGT AS THE HIGH PRES CENTER SHIFTS INTO WRN AR.
Latest surface analysis has a fairly weak low pressure center along the Minnesota/Iowa border, with an associated cold front extending southeast toward the tip of west-central Illinois before curving back southwest into the southern Plains. Model guidance overall has slowed the local passage of the cold front considerably in the past 24 hours, with the front now not expected to reach the Indiana border much before 00Z this evening. Highs will only be near 50 degrees around Galesburg (where the front arrives earliest), but will reach as high as the lower 70s in far southeast Illinois (where the front doesn't arrive until evening).
130 AM EDT SUN MAR 27 2016 HIGH PRESSURE OVER THE EASTERN LAKES WILL MOVE OFF THE NEW ENGLAND COAST LATE TONIGHT. THIS WILL ALLOW A LOW PRESSURE SYSTEM TO TRACK ACROSS THE LOWER LAKES SUNDAY NIGHT INTO MONDAY DRAGGING ANOTHER COLD FRONT ACROSS THE FORECAST AREA. A QUIET NIGHT ON TAP AS HIGH PRESSURE REMAINS THE DOMINANT FEATURE. THE HIGH WILL SHIFT OFF THE NEW ENGLAND COAST LATE TONIGHT. BUT WITH A SOUTHERLY FLOW ON THE BACKSIDE OF THE HIGH TEMPS WILL BE A FEW DEGREES WARMER TONIGHT THAN YESTERDAY. BY 00Z MON GFS HAS THE LOW INTO WEST CENTRAL OHIO. THAT SAID EXPECT THE LOW TO TRACK NE ACROSS OHIO SUNDAY NIGHT AND REACH THE EASTERN BASIN OF LAKE ERIE BY DAYBREAK MONDAY. AS THE LOW TRACKS ACROSS OHIO WILL TAP INTO SOME GULF MOISTURE AIDED BY LOW LEVEL JET.
321 AM CDT SUN MAR 27 2016 AT 300 AM A CDFNT WAS EXTENDING ACROSS CENTRAL MO WHILE THE UPPER TROF AXIS WAS STILL BACK OVER WRN KS. AHEAD OF THE UPPER TROF/CDFNT IS A STREAM OF MOISTURE MOVING ACROSS MUCH OF THE SERN US. OTHERWISE TEMPS ACROSS THE CWA WERE IN THE LOW 60S UNDER MOSTLY CLOUDY SKIES. AS THE UPPER TROF/CDFNT EDGES CLOSER TO THE TN VALLEY TODAY.
EASTER WILL BE DRY AND WARMER THAN YESTERDAY WITH JUST A LIGHT WIND AND CLEARING SKIES. THE UPPER TROUGH AXIS HAS PASSED OFF TO OUR EAST AND DRY WEATHER IS EXPECTED TODAY AND TONIGHT. BUT THIS SNOW IS ASSOCIATED WITH THE UPPER TROUGH AND WILL REMAIN SOUTH AND EAST OF US AS IT PUSHES FURTHER AWAY FROM OUR AREA THROUGH THE MORNING HOURS. WHICH WILL KEEP THE WIND LIGHT AND WE CAN EXPECT A GRADUAL WIND SHIFT FROM NORTHWEST THIS MORNING TO A SOUTHERLY WIND BY LATER TONIGHT ONCE THE HIGH PASSES EAST. THIS SOUTHERLY WIND TONIGHT WILL ALSO KEEP TEMPERATURES A FEW DEGREES WARMER THAN LAST NIGHT. EVENTUALLY LATER THIS EVENING WE SHOULD START SEEING SOME WARMER RETURN SOUTHERLY FLOW.
315 AM CDT SUN MAR 27 2016 A cold front was bisecting the forecast area from northeast to southwest and this will continue to push through the area, clearing south central Missouri this afternoon. High pressure then builds across the area tonight setting the stage for a cold night. With the clear skies and light winds expect temperatures to approach the freezing mark and thus have added areas of frost to the grids.
