633 AM EDT WED MAR 11 2015 LOW PRESSURE WAS PASSING NORTH OF THE REGION THIS MORNING BUT THE COLD FRONTAL PASSAGE WILL BE DELAYED UNTIL LATE TONIGHT.
THE QUIET WEATHER PATTERN WILL CONTINUE TODAY AS SHORT RANGE MODELS INDICATE AN UPPER LEVEL TROUGH OF LOW PRESSURE BASICALLY STALLING OUT ACROSS THE SOUTH PLAINS OF OKLAHOMA AND TEXAS. THIS WILL BRING ABOUT AN EAST TO SOUTHEASTERLY FLOW TO WESTERN KANSAS THIS AFTERNOON HELPING TO DRAW WARMER AIR INTO THE REGION. ALONG WITH AMPLE SUNSHINE, LOOK FOR HIGHS GENERALLY UP INTO THE LOWER TO MID 70S(F) THIS AFTERNOON. UNDER THE INFLUENCE OF A MODEST SOUTHERLY FLOW, LOWS ARE EXPECTED ONLY DOWN INTO THE LOWER TO MID 40S(F) WEDNESDAY NIGHT WITH A FEW UPPER 30S(F) STILL POSSIBLE IN SOME LOCATIONS IN WEST CENTRAL KANSAS. AN UPPER LEVEL TROUGH OVER THE CENTRAL PART OF THE LOWER 48 STATES WILL SHEAR OUT OVER THE NEXT ONE TO TWO DAYS.
A COLD FRONT WAS LOCATED FROM SHEYBOYGAN WISCONSIN TO FAIRCHILD IOWA. MEANWHILE SOUTH OF THIS HIGHWAY. THE LOWEST VISIBILITY AT TIME IS 3/4 OF A MILE ART BOSCOBEL WISCONSIN. SO WE WILL DEFINITELY BE COOLER TODAY. SO WAS MORE CONFIDENT TO GO 3 TO 5 DEGREES WARMER THAN THE MODEL CONSENUS.
BDL WITH UPPER RIDGING OVER THE BAHAMAS AND A DEEP TROUGH OVER THE CENTRAL PLAINS. SOUTHWEST FLOW ALOFT FROM THE LOWER MISSISSIPPI TO THE TENNESSEE VALLEYS WILL KEEP A STREAM OF GULF MOISTURE INTO THE DEEP SOUTH WITH LITTLE VARIATION IN OVERALL PATTERN.

WEAK UPPER LEVEL RIDGING WILL MOVE OVERHEAD TODAY WHILE AN UPSTREAM TROUGH DIGS TOWARD THE PACIFIC COASTLINE. WEAK MIXING TODAY IN MOST AREAS SHOULD KEEP HIGHS IN THE LOW 70S ACROSS MUCH OF THE REGION.
A DEVELOPING LOW OVER THE WRN GULF WILL FURTHER AID IN THE TRANSPORT OF RICH GULF MOISTURE NWRD AS THE LOW IS PROGGED TO TRACK ALONG OR NEAR SABINE PASS LATER TONIGHT THROUGH THURSDAY MORNING WITH THE HEAVY RAIN AXIS GENERALLY INVOF AND EAST OF THE LOW FROM DEEP E TX ACROSS NRN LA AND SRN AR. WITH A COUPLE MORE INCHES POSSIBLE ESPECIALLY ALONG AND EAST OF THE I-49 CORRIDOR PER THE SIMILAR GFS/ECMWF SOLUTIONS WHICH SEEM MORE REASONABLE THAN THE NAM WHICH CONTINUES TO SHOW A MORE WWRD EXPANSION OF THE HIGHER PRECIPITATION. SOME ISOLD TSTMS WILL ALSO BE POSSIBLE ON THURSDAY AS THE LOW EJECTS N/NE.
156 AM EDT WED MAR 11 2015 WEAK LOW PRESSURE MOVING SOUTH OF KEYSTONE STATE TONIGHT WILL BRING SOME RAIN TO THE AREA INTO EARLY WEDNESDAY MORNING.
HIGH PRESSURE AT THE SURFACE AND ALOFT WILL REMAIN OVER THE AREA THROUGH TOMORROW AFTERNOON. GRADIENTS WILL SWITCH TO SOUTHERLY TOMORROW AS A LEE TROUGH OF LOW PRESSURE DEVELOPS OVER THE NORTHEAST COLORADO PLAINS. LEADING TO HIGH TEMPERATURES ABOUT 5 DEGREES WARMER THAN THIS AFTERNOON. UPPER LEVEL RIDGE AXIS WILL SHIFT EAST OF THE FORECAST AREA WEDNESDAY NIGHT ALLOWING AN UPPER LEVEL TROUGH TO DROP ACROSS THE GREAT BASIN BY THURSDAY.
AS THE LOW PRESSURE REMAINS OVER NORTHERN MEXICO. THE CIGS LIFT WEDNESDAY AFTERNOON AS LOW PRESSURE OVER THE GULF MOVES FURTHER EAST. THE LOW PRESSURE OFFSHORE WILL STRENGTHEN DURING THE DAY INCREASING NORTH WINDS WITH GUSTS UP TO 20 KNOTS IN THE AFTERNOON.

FOLKS WILL NEED TO SLOW DOWN AND USE THE LOW BEAMS. TEMPERATURES THIS AFTERNOON SHOULD BE EVEN WARMER THAN YESTERDAY. THE UPPER TROUGH PARKED OVER THE SOUTHERN PLAINS WILL RETROGRADE TO THE WEST SLIGHTLY ON THURSDAY.
339 AM CDT Wed Mar 11 2015 Mid-level closed low continues to linger and spin over the central and southern plains through tonight. With the trough axis in close proximity to the KS river valley ground fog may develop in some of these locations given the clear skies, calm winds, and added moisture from the melted ground frost. There is better agreement that mixing heights reach roughly 800 mb, which gives most locations high temperatures in the low to mid 70s. A weak upper level trough will move east into the northern high plains and phase with another weak upper low across west TX. The NAM and SREF surface dewpoints look to high, went more with an ARW-Wmodel blend for dewpoints in the lower to mid 30s.
DID ADJUST OVERNIGHT LOW TEMPERATURES HIGHER DUE TO THE DEWPOINTS STILL HOLDING IN THE LOW 60S AND TO BETTER DEPICT THE FRONT SLOWLY MOVING SOUTHEAST ACROSS NW AL DURING OVERNIGHT HOURS BEFORE STALLING. WIND DIRECTION IS ALSO EXPECTED TO CHANGE AT KHSV AS WEAK SFC COLD FRONT PASSES AROUND 10Z.
WEAK UPSLOPE FLOW AND A SHALLOW LAYER OF MOISTURE WILL HELP POPS AND QPF LINGER THE LONGEST IN THE HIGH TERRAIN. THE CLOSED UPPER LEVEL LOW STILL LINGERING OVER TX WILL CONTINUE TO INTENSIFY. THE LOW WILL EVENTUALLY MOVE NORTH. UP THE LOWER MISSISSIPPI VALLEY AND THE OHIO VALLEY.
TODAY AND TONIGHT BRIEF DIP IN THE HEIGHT FIELD ALLOWING A WEAK COLD FRONTAL BOUNDARY TO SAG SOUTHEAST AND ACROSS SE MICHIGAN EARLY THIS MORNING. STEADY DRYING THROUGH THE LOWER LEVELS WILL TAKE A STRONGER HOLD BY EVENING AS HIGH PRESSURE STEADILY BUILDS ACROSS THE LOWER PENINSULA. LOWS PREDOMINATELY IN THE LOWER AND MIDDLE 20S.
Weak high pressure over the region today will provide a great/warm day once the fog burns off.
UPPER LEVEL TROUGH ORIENTED FROM ERN KS TO EASTERN CHIHUAHUA WILL REMAIN NEARLY STATIONARY AND PERHAPS STRENGTHEN EVER SO SLIGHTLY THROUGH EARLY THURSDAY MORNING. THE UA TROUGH DRAPED FROM THE CNTRL PLAINS SOUTHWEST TO ACROSS THE SRN PLAINS EARLY THIS MORNING.
259 AM CDT Wed Mar 11 2015 Similar conditions to yesterday will once again yield temperatures in the upper 60s and lower 70s across the region today, although weak northerly surface flow over far northern MO may keep those areas a couple of degrees cooler.
LOW PRESSURE WAS PASSING NORTH OF THE REGION THIS MORNING BUT THE COLD FRONTAL PASSAGE WILL BE DELAYED UNTIL LATE TONIGHT.
UPPER LEVEL TROUGH REMAINS OVER THE AREA AND SUSPECT WE WILL SEE ANOTHER DAY OF MAINLY ENHANCED CUMULUS CLOUDS AND A FEW SPOTTY SHOWERS OR A VERY ISOLATED THUNDERSTORM OVER THE FAR SOUTHERN TEXAS PANHANDLE. AND COUPLED WITH THE LOW RELATIVE HUMIDITY VALUES/ABOVE NORMAL TEMPERATURES.
TONIGHT AND WEDNESDAY A WEAK COLD FRONT WILL MOVE ACROSS THE REGION THIS EVENING. THE AIR BEHIND IT IS NOT VERY COLD SO DO NOT EXPECT TEMPERATURES TO FALL MUCH TOO MUCH BELOW FREEZING.

WITH HIGHS IN THE LOW TO MID 80S. DEEP LAYERED RIDGING WILL REMAIN ENTRENCHED ACROSS THE AREA DUE TO THE ANCHORED LONG WAVE TROUGH OVER THE WEST. THIS RIDGING WILL ACT TO SUPPRESS SHOWER ACTIVITY.
UPPER RIDGING WILL FLATTEN OVER THE REGION TODAY AS A PACIFIC TROUGH APPROACHES THE AREA. LEE TROUGHING WILL SUPPORT WINDY CONDITIONS OVER KLVM AND BIG TIMBER. THE PACIFIC TROUGH WILL CROSS THE AREA TONIGHT THROUGH THU AND THE ASSOCIATED COLD FRONT WILL MOVE THROUGH TONIGHT. KEPT POPS OVER AND NEAR THE MOUNTAINS TONIGHT AND SPREAD A SLIGHT CHANCE ACROSS ALL OF THE LOWER ELEVATIONS FOR THU. THE SW MOUNTAINS AND NE BIGHORNS WILL HAVE THE HIGHEST PRECIPITATION CHANCES DUE TO UPSLOPING AND LOCATION OF THE DEEPEST MOISTURE. A SOLID RIDGE WILL BE IN CONTROL OVER OUR REGION TO END THE WORK WEEK WITH A CONTINUATION OF MILD TEMPERATURES.
TEMPERATURES SOARED TODAY AHEAD OF THE COLD FRONT THAT MOVED THROUGH. THE COOLER AIR BEHIND THE FRONT IS AT -2 TO -4C AT 850 MB COMPARED TO +4 TO +6 PREFRONTAL. WITH THE RIDGE OF HIGH PRESSURE OVER THE REGION ON WEDNESDAY THERE WILL BE NO PRECIPITATION. SFC RIDGING MOVES OFF TO THE EAST OF THE FORECAST AREA WEDNESDAY NIGHT ALLOWING FOR A WAA PATTERN TO EMERGE. RIDGING ALOFT REMAINS OVER THE EASTERN PORTION OF THE AREA.
SYNOPTIC PATTERN REMAINS GENERALLY UNCHANGED WITH AN UPPER TROF ANCHORED TO THE WEST EXTENDING FROM THE CENTRAL PLAINS SW THROUGH TX AND OLD MEXICO TWD THE BAJA. THERE APPEARS TO BE AT LEAST TWO PRIMARY LOBES OF ENERGY TRANSLATING THROUGH THE BASE OF THE TROF. ADDITIONAL PACIFIC ENERGY ENTERING THE MEAN TROF WILL CAUSE IT TO DIG/RETROGRADE WWD OVER THE WEEKEND. 13 A NEARLY STATIONARY FRONT EXTENDING FROM NEAR VERMILION BAY SOUTH SOUTHWEST THROUGH THE WESTERN GULF IS FORECAST TO RETREAT A BIT TO THE WEST TODAY AS AN AREA OF LOW PRESSURE DEVELOPS ALONG THE BOUNDARY OVER THE WEST CENTRAL GULF. THIS LOW IS FORECAST TO TRACK NORTHWARD THROUGH THE COASTAL WATERS AND THROUGH THE SABINE RIVER VALLEY TONIGHT AND THURSDAY.
AS AN UPPER LEVEL TROUGH GRADUALLY EXITS EASTWARD. A RIDGE OF HIGH PRESSURE WILL CROSS WEDNESDAY RESULTING IN THE WARMEST DAY OF THE WEEK. AN UPPER LEVEL LOW PRESSURE SYSTEM WILL DROP SOUTHWARD THROUGH THE STATE AND INTO NORTHWEST MEXICO DURING THE LATTER HALF OF THE WEEK. A BACK DOOR COLD FRONT WILL ALSO ARRIVE WITH COOLER TEMPERATURES.
SHORT TERM: (Through Late This Afternoon) A weak cold front associated with a low pressure system over Ontario will move into the CWA today, then stall and lift back northeastward as a warm front tonight in response to a developing low pressure system over the plains. Today should be quite warm across most of the CWA with most locations reaching the 60s and parts of central MO even hitting the low 70s.
219 AM MDT WED MAR 11 2015 EARLY MORNING WV IMAGERY AND RAP UPPER LEVEL ANALYSIS SHOW RIDGE EXTENDING FROM THE SW US INTO THE CENTRAL ROCKIES AND OVER OUR CWA. AT THE SURFACE WEAK HIGH PRESSURE IS IN PLACE OVER OUR CWA. WITH LOW PRESSURE EXTENDING FROM EASTERN WYOMING AND NEBRASKA PANHANDLE INTO NORTHEAST COLORADO.
THE CENTER OF HIGH PRESSURE WILL CONTINUE TO SHIFT EAST ALLOWING SOUTHERLY RETURN FLOW. MODELS IN GENERAL AGREEMENT PUSHING WARMER AIR BACK NORTH ACROSS THE FA.

ARCTIC HIGH PRESSURE CENTERED OVER THE EASTERN DAKOTAS WILL DRIFT SOUTHEAST TONIGHT. SURFACE PRESSURE FALLS ACROSS THE LEE SIDE OF THE ROCKIES WILL BEGIN THIS EVENING AND THE LOW WILL MOVE INTO THE WESTERN DAKOTAS MONDAY. THIS LOW WILL BE THE FOCUS FOR ANOTHER ROUND OF LIGHT SNOW MONDAY.
WITH EASTERN TROUGHING AND RIDGE ALONG THE WEST COAST. BY THE WEEKEND THE HUDSON BAY LOW WILL BE DISPLACED NORTHWARD AND THE UPPER FLOW WILL BECOME MORE ZONAL AS THE WESTERN RIDGE FLATTENS AND SHIFTS A BIT EASTWARD.
THE COLD FRONT WAS LOCATED JUST SOUTH OF SCOTTSBORO. WINDS WILL BECOME GUSTY JUST AHEAD AND THEN BEHIND THE COLD FRONT. THE COLD FRONT IS MOVING INTO THE STATE.
LEADING TO MUCH WARMER TEMPERATURES AREA- WIDE AS MOST LOCATIONS MIX NICELY BY AFTERNOON. STILL ENOUGH MOISTURE EMBEDDED IN THE FLOW TO PRODUCE SOME LIGHT SNOW OVER THE HIGHER PEAKS OF THE CENTRAL MOUNTAINS.
WEAK HIGH PRESSURE ALOFT WILL PREVAIL OVER THE AREA OVERNIGHT. EXPECT A LOW PRESSURE SYSTEM TO MOVE ACROSS THE REGION ON MONDAY. FOLLOWED BY HIGH PRESSURE ALOFT MONDAY NIGHT.
248 AM EST MON FEB 2 2015 LOW PRESSURE EXITING NORTHEAST OF THE AREA. WHIPS COLD FRONT OVERNIGHT/EARLY MONDAY.
340 AM EST MON FEB 2 2015 LOW PRESSURE EXITING NORTHEAST OF THE AREA. WHIPS COLD FRONT OVERNIGHT/EARLY MONDAY.
COLD FRONT HAS PUSHED THROUGH AND CONTINUE TO HAVE VFR CIGS. HIGH PRESSURE BUILDING THROUGH THE PLAINS WILL SLOWLY SETTLE OVER TX AND ALLOW FOR WINDS TO DECREASE. /ISSUED 815 PM CST SUN FEB 1 2015/ THE COLD FRONT WAS MOVING OFF THE COAST AT 8 PM. PRE-FRONTAL TROUGH IS WORKING THROUGH KSGR/KHOU WITH A FEW SHOWERS AND ISO TSRA OVER KHOU. COLD FRONT WAS PUSHING THROUGH CONROE TO COLUMBUS.
153 AM CST MON FEB 2 2015 THE SYNOPTIC SETUP EARLY THIS MORNING CONSISTED OF UA TROUGHINESS ACROSS THE MID-WEST AND ERN CONUS. UA RIDGING ACROSS THE WRN CONUS THUS PROMOTING DRY NW FLOW ALOFT FOR THE SOUTHERN PLAINS. WHILST SFC LEE TROUGHING BECOMES ESTABLISHED AND THUS PROMOTE SFC WINDS TO VEER TO THE S-SW BY THIS AFTN. A GENERALLY MILD WEEK AHEAD AS THE FCST AREA WILL SIT UNDER WNW TO NW FLOW ALOFT SITUATED BETWEEN A WRN CONUS RIDGE AND ERN CONUS TROUGH.
A weak trof embedded in the northwest flow aloft is currently moving through central and southwest MT, generating widespread low- and mid-level cloud cover and isolated areas of light snow (mainly from KHVR-to-KLWT-to-KBZN).
At this time, it appears up to an inch of snow is possible, mainly over the higher elevations of the MO Ozarks.
THE COLD FRONT IS PUSHING THROUGH LOWER ACADIANA THIS EVENING AND RAIN CHANCES WILL DECREASE AS THE FRONT PUSHES FARTHER EAST AND SOUTH OVER THE NEXT SEVERAL HRS. /ISSUED 433 PM CST SUN FEB 1 2015/ A SOMEWHAT WIDE AND BROKEN LINE OF SHOWERS AND THUNDERSTORMS HAS DEVELOPED AND IS PUSHING THROUGH THE AREA THIS AFTERNOON AHEAD OF AN APPROACHING COLD FRONT. SUNNY SKIES DRIER AIR AND SIGNIFICANTLY COOLER TEMPERATURES IN STORE FOR MONDAY AS HIGH PRESSURE BUILDS IN BEHIND THE FRONT.
REGIONAL RADAR IS SHOWING SOME LIGHT BANDS OF SNOW ACROSS CENTRAL AND EASTERN MONTANA ASSOCIATED WITH THIS LOW.

438 AM EST MON FEB 2 2015 LOW PRESSURE TRACKS SOUTH OF NEW ENGLAND TODAY.
339 AM CST MON FEB 2 2015 NORTH WINDS WILL DIMINISH THIS MORNING AS HIGH PRESSURE SETTLES OVER THE AREA. SOUTHERLY WINDS WILL RETURN BY AFTERNOON AS THE RIDGE OF HIGH PRESSURE MOVES OFF TO THE EAST BUT IT WILL STILL BE A CHILLY AFTERNOON WITH MOST PLACES REMAINING IN THE 30S FOR HIGHS TODAY.
335 AM CST MON FEB 2 2015 ANALYSIS AT 2 AM SHOWS CLEAR SKIES WITH DIMINISHING NW WINDS AS HIGH PRESSURE MOVES IN FROM THE NW.
1143 PM CST Sun Feb 1 2015 A strong cold front was sweeping across the forecast area early this afternoon, with temperatures rapidly dropping in its wake as brisk northwest winds usher in a much colder airmass. Expect temperatures to continue to fall into the 20s by this evening, eventually dropping into the low to mid teens by Monday morning. With upstream obs across Nebraska already in the low single digits, it's not beyond the realm of possibility that a few locations across southeastern Kansas may flirt with sub-10 degree lows. The best chance for light snow late this evening will be across Central Missouri as the upper level trough axis swings through.
342 AM CST Mon Feb 2 2015 Scattered flurries and light snow showers will be possible for awhile early this morning, but most of the day will be precip free as high pressure builds in from the west. The high will bring a shot of cold air with it. Still, readings will likely fall into the lower half of the 20s. A brief warming trend will get going Tue/Wed as the high moves off to the east and winds become more southerly. Will go with small rain chances Wed afternoon as yet another cold front pushes in from the nw.
STRONG UPPER LEVEL LOW STILL PROVIDING QG FORCING RIGHT OVER THE I80 CORRIDOR CURRENTLY. AS RIDGE SETTLES INTO THE AREA TEMPERATURES WILL BE WELL BELOW ZERO OVER THE WEST AND NORTHWEST WITH RIDGE AXIS APPROACHING THE AREA.
WITH CONTINUED BELOW NORMAL READINGS RANGING FROM THE LOW TEENS /LADYSMITH WI/ TO AROUND 20 DEGREES /MADISON MN/. THE INCREASE IN CLOUDS AND BRIEF BRUSH WITH SOUTHERLY FLOW WILL YIELD WARMER AND MORE TYPICAL NIGHTTIME LOWS FOR EARLY FEBRUARY.
With that said, road conditions will likely remain icy tonight with temperatures at or below freezing. /SVH 06Z TAFS: The mid level cold front has pushed east of the region this evening.
441 AM EST MON FEB 2 2015 LIGHT SNOW ASSOCIATED WITH DEPARTING LOW PRESSURE WILL AFFECT THE REGION EARLY THIS MORNING. A MUCH COLDER AIRMASS WILL SETTLE ACROSS THE REGION TODAY IN THE WAKE OF THE LOW.
1042 PM CST SUN FEB 1 2015 TEMPERATURES HAVE BEEN STEADILY DROPPING ALL EVENING WITH THE NORTHWEST COUNTIES ALREADY AT FREEZING AS OF 10 PM. WINDY AND COOLER CONDITIONS WERE OCCURRING ACROSS ALL BUT OUR FAR SOUTHEAST COUNTIES WHERE THE COLD FRONT IS EXPECTED TO MOVE THROUGH LATER THIS AFTERNOON. OVERNIGHT LOW TEMPERATURES WILL RANGE FROM THE MID 20S ACROSS THE RED RIVER VALLEY TO THE LOWER 30S IN CENTRAL TEXAS.
346 AM CST Mon Feb 2 2015 Early this morning radar and surface observations show some lingering light snow (flurries really) persisting across central Missouri as the deformation zone following the upper level trough swings through.
With this, thinking 1 to 3 inches of additional snowfall may be possible tonight, with the highest amounts being across the northern third of the CWA, or where the warning is located at. Southeast counties may get a little warmer given the lack of snow down there. Precip type for all systems looks to be mainly snow, except for Wed afternoon in the southeast, where temps should warm enough above freezing that precip-type could be a mix of rain and snow or just rain all rain around Lawrenceville. Then a warming trend will be see for the rest of the week and into the weekend, with temps rising to above freezing over most of the area. As high pressure builds in from the west, expect light winds veering to the W/SW by Monday afternoon.
436 AM EST MON FEB 2 2015 RAIN WILL CHANGEOVER TO SNOW THIS MORNING AS MUCH COLDER AIR MOVES IN BEHIND A DEPARTING LOW PRESSURE SYSTEM.
BUT HIGH PRESSURE WILL STRENGTHEN BY THIS AFTERNOON.
304 AM CST MON FEB 2 2015 AS OF 09Z THE COLD FRONT THAT BROUGHT THE HEAVY RAIN OVERNIGHT IS EAST OF THE FORECAST AREA. WATER VAPOR ANALYSIS INDICATES THAT THE TRAILING UPPER TROUGH IS PUSHING THROUGH ARKANSAS AND INTO MISSISSIPPI AS WELL. TEMPS ARE FALLING QUICKLY WITH THE UPPER TROUGH WITH TEMPS ALREADY BELOW FREEZING IN EASTERN ARKANSAS. AS THE UPPER TROUGH MOVES THROUGH. THE NEW FORECAST IS A DEGREE OR TWO COOLER THAN THE PREVIOUS BUT MAY STILL BE TOO WARM IN REALITY AND MAY NEED TO BE MONITORED. LOWS RIGHT NOW ARE FORECAST IN THE LOWER TO MIDDLE 20S. HIGH PRESSURE.
A STRONG COLD FRONT WILL APPROACH FROM THE WEST TONIGHT AND SWING ACROSS CENTRAL NC ON MONDAY. ONGOING SHOWERS MONDAY MORNING ARE EXPECTED TO PROGRESS EAST TO THE COASTAL PLAIN BY 15Z AS AN UPPER TROUGH AND COLD FRONT SWING ACROSS THE AREA.
BY MORNING ANOTHER OCCLUDED FRONT WILL MOVE ONSHORE AND A WARM FRONT WILL PUSH INTO CENTRAL OREGON.
COLD FRONT WILL PASS INTO SOUTH FLORIDA BY ABOUT 00Z SO WILL NOT CARRY ANY POPS THIS EVENING.
1122 PM CST SUN FEB 1 2015 THE COLD FRONT HAS PUSHED THROUGH ALL OF THE TERMINALS AS OF LATE THIS EVENING.
However, as much colder air is advected swd behind the low, thermal profiles will be such that any clouds cud produce at least flurries thru the night, despite loosing cloud from the top down. Another issue to watch will be freezing of any water on roads as temps drop this eve.
348 AM CST Mon Feb 2 2015 The upper low that brought rain to the area recently has dropped down into Mexico, but most of the moisture has pushed off to the east so a drier weather pattern can be expected.
92 TEMPERATURES HAVE BEEN STEADILY DROPPING ALL EVENING WITH THE NORTHWEST COUNTIES ALREADY AT FREEZING AS OF 10 PM. WINDY AND COOLER CONDITIONS WERE OCCURRING ACROSS ALL BUT OUR FAR SOUTHEAST COUNTIES WHERE THE COLD FRONT IS EXPECTED TO MOVE THROUGH LATER THIS AFTERNOON. OVERNIGHT LOW TEMPERATURES WILL RANGE FROM THE MID 20S ACROSS THE RED RIVER VALLEY TO THE LOWER 30S IN CENTRAL TEXAS.
RIDGE AXIS TO OUR EAST CONTINUES A SLOW TRUDGE TOWARDS THE MISSISSIPPI AND WILL PRODUCE SOUTHERLY FLOW DURING THE OVERNIGHT HOURS. AFTERNOON TEMPERATURES HAVE STRUGGLED TO REACH THE MIDDLE TEENS TO LOWER 20S WHICH ENDED UP BEING COOLER THAN WHAT MOST GUIDANCE INDICATED. SO TENDED TO GO A LITTLE UNDER THE WARMER GUIDANCE.
322 AM CST MON FEB 2 2015 HIGH PRESSURE OVER THE EASTERN HALF OF KANSAS EARLY THIS MORNING IS PROGGED TO TRANSLATE EASTWARD ACROSS THE MIDDLE MISSISSIPPI VALLEY TODAY ALLOWING SOUTHERLY WINDS TO RETURN. TEMPERATURES WILL BEGIN TO MODERATE WITH HIGHS TODAY RANGING FROM NEAR 40 ACROSS CENTRAL KANSAS TO THE LOW 30S OVER EASTERN KANSAS. MORE SEASONABLE TEMPERATURES ARE ANTICIPATED TONIGHT WITH LIGHT SOUTHWEST WINDS AND LOWS IN THE LOWER 20S.
A short lull in the weather pattern tonight as high pressure briefly moves through.
KEPT TEMPS TONIGHT WARMER THAN THE PAST FEW NIGHTS.
AREA RADARS ARE DEPICTING A LINE OF RAIN SHOWERS ASSOCIATED WITH A PRE-FRONTAL TROUGH PUSHING TO THE SOUTHEAST ACROSS EASTERN TEXAS. A DRY COLD FRONT IS PUSHING ACROSS CENTRAL TEXAS AND EXPECTED TO REACH THE HILL COUNTRY AROUND 3 PM AND BETWEEN 5 AND 6 ALONG INTERSTATE 35. THE COOL AIRMASS WILL BRING OVERNIGHT LOWS TO THE LOWER 30S ACROSS THE HILL COUNTRY TO MID AND UPPER 30S ALONG INTERSTATE 35 WITH LOWER 40S ACROSS THE COASTAL PLAINS. WITH HIGHS ONLY IN THE LOW AND MID 50S. A STRONG HIGH PRESSURE SYSTEM CENTERED OVER THE SOUTHERN PLAINS IS FORECAST TO PUSH TO THE SOUTHEAST AND INTO THE SOUTHERN STATES BY MONDAY AFTERNOON.
/ISSUED 347 PM CST SUN FEB 1 2015/ (Tonight and Monday) Post-frontal stratus was slow to dissipate this afternoon, and highs were a couple degrees cooler than expected. (Monday night through Sunday) Mainly a dry forecast this week with a couple of weak cold fronts affecting the area.
