949 PM MST SAT JAN 24 2015 MSAS PRESSURE TENDENCY TRENDS OVER THE PAST FEW HOURS INDICATE PRESSURE FALLS ARE STEADILY INCREASING OVER THE HIGH COUNTRY. WHILE THE LEESIDE TROUGH IS WEAKENING. CANCELLED THE HIGH WIND WARNING EARLY AS THE THREAT FOR STRONG WINDS IS PRETTY MUCH OVER DUE TO THE RELAXING GRADIENT. IT WILL BE GUSTY TONIGHT FOR MANY PANHANDLE LOCATIONS WITH GUSTS OF 35 TO 40 MPH ESPECIALLY ALONG EXPOSED RIDGETOPS BUT SHOULD REMAIN UNDER ADVISORY CRITERIA. AN UPPER LEVEL RIDGE WILL BUILD OVER THE ROCKIES THROUGH THIS TIME WITH MUCH DRIER AIR FILTERING INTO THE CWA AND MINIMIZING ANY CHANCE FOR PRECIP.
1159 PM EST SAT JAN 24 2015 AVIATION A COLD FRONT WILL COME THROUGH TONIGHT WITH SOME FLURRIES OR LIGHT SNOW SHOWERS. COLD FRONT MOVES SOUTH THROUGH LOWER MICHIGAN THIS EVENING WITH VERY LIGHT PRECIPITATION. THE UPPER TROUGH AMPLIFIES AND GOES NEGATIVE TILT ON MONDAY AND THE CLIPPER BOMBS OUT OVER THE ATLANTIC. A WEAK CLIPPER DIVES SOUTHEAST ACROSS WISCONSIN AND SHEARS OUT IN THE AMPLIFYING TROUGH MONDAY NIGHT.
AND WITH WARMER AIR OVER NEBRASKA AND IOWA BEING PULLED NORTHEASTWARD TONIGHT INTO NORTHEAST IOWA/FAR SOUTHWEST WI. WITH THE MAIN ACCUMULATING SNOW OCCURRING SOUTH AND WEST OF THE HIGHWAY 52 CORRIDOR ACROSS SOUTHEAST MINNESOTA/NORTHEAST IOWA. THE LOW EXITS THE REGION ON SUNDAY WITH SNOW ENDING. A WEAK FRONT MOVES ACROSS THE REGION SUNDAY NIGHT THOUGH MONDAY AN MAY GENERATE SOME LIGHT SNOW WITH A SWITCH OVER TO FREEZING DRIZZLE MONDAY AFTERNOON INTO MONDAY EVENING AS ICE IS LOST ALOFT. A LIGHT GLAZE OF ICE IS POSSIBLE IF THE FREEZING DRIZZLE DEVELOPS.
257 AM EST SUN JAN 25 2015 WEAK HIGH PRESSURE WILL BE IN CONTROL TODAY WITH THE NEXT FAST MOVING LOW PRESSURE SYSTEM CROSSING THE REGION TONIGHT AND MONDAY WITH A SLIGHT CHANCE SHOWERS.
HIGH CLOUDS WILL CONTINUE STREAMING ACROSS THE REGION AS AN UPPER LOW IS POSITIONED NEAR THE BAJA PENINSULA. WITH TEMPERATURES WARMING INTO THE LOW 70S AREA WIDE.
IT APPEARS THAT THE COLUMN LOSES ICE YET KEEPS SOME STRONG LOW LEVEL FORCING/MOISTURE IN PLACE AS THE WARM FRONT MOVES IN. WITH SURFACE TEMPERATURES STARTING OFF BELOW FREEZING.
A WEAK COLD FRONT WILL PASS THROUGH THE AREA TODAY. BUT NOT MUCH CHANGE OTHER THAN BREEZY AND SLIGHTLY DRIER AIR AS WEAK HIGH PRESSURE BUILDS IN BEHIND THE FRONT.
321 AM CST SUN JAN 25 2015 COLD FRONT CURRENTLY ENTERING OSAGE COUNTY WILL SWEEP ACROSS THE AREA TODAY. BRINGING GUSTY NWLY WINDS AND COOLER TEMPERATURES. THE COOLER WEATHER WILL ONLY LAST A DAY.
A cold front will move through West Central Texas mid/late morning, shifting winds to the northwest and north. Statistical guidance numbers are all over the board tomorrow, but we've leaned toward the warmer GFS based MOS, with highs generally in the mid 60s.
NORTHWESTERLY WINDS BEHIND A WEAK COLD FRONT WILL STRENGTHEN BY LATE MORNING BEFORE DECREASING AND BACKING TO A MORE WESTERLY DIRECTION BY AROUND SUNSET TOMORROW EVENING. A WEAK COLD FRONT WILL PASS THIS EVENING BRINGING A SHIFT IN THE WINDS TO NORTHWESTERLY. TEMPERATURES HAVE MANAGED TO CLIMB ABOVE FREEZING AREA WIDE. THIS SYSTEM WILL FORCE A WEAK COLD FRONT THROUGH THE PANHANDLES OVERNIGHT. WITH SLIGHTLY-ENHANCED NORTHWEST POST-FRONTAL WINDS EXPECTED TO KEEP THE LOWER ATMOSPHERE MIXED ENOUGH TO BOTH PRECLUDE ANY PATCHY FOG THAT OTHERWISE MIGHT RESULT FROM TODAY/S SNOWMELT.
400 AM CST Sun Jan 25 2015 Sfc obs show a weak cold front to the north of the region, w/buffer soundings bringing fropa to KMAF at around 10Z. Further west, WV imagery shows a massive cut-off low separated from upper-lvl flow and parked off the coast of Baja. In between this trough and NW flow to the east, models develop a highly-amped ridge over West Texas/Southeast New Mexico over the next few days. This feature is forecast to build east and flatten into midweek as the upper trough shears out as it moves NE back into the jetstream. Upper ridging will allow for a brief respite from the cold temps of late.
324 AM CST SUN JAN 25 2015 IMPRESSIVE VORT MAX SPIRALING SOUTHEAST OVER EASTERN KS THIS MORNING WILL PUSH A WEAK COLD FRONT THROUGH MUCH OF THE CWA BEFORE DAYBREAK AHEAD OF GUSTY NORTH WINDS. MILD SURFACE RIDGING THEN OVERSPREADS MUCH OF WEST TX TONIGHT FROM NEW MEXICO COMPLETE WITH LIGHT WEST WINDS AND CLEAR SKIES. DRY AIR AND MILD PATTERN WILL PREVAIL AT LEAST THROUGH MID WEEK AS HIGH AMPLITUDE RIDGE BECOMES ELONGATED FROM THE NORTHERN ROCKIES S/SE THROUGH THE SOUTHERN PLAINS.
TOMORROW MORNINGS COLD FRONT IS PUSHING THROUGH SOUTHEAST KANSAS AND ENTERING NORTHWEST OKLAHOMA AT 9 PM. CLOSED LOW NEAR BAJA AND A POSITIVELY TILTED UPPER TROUGH SWINGING DOWN FROM CANADA. /ISSUED 254 PM CST SAT JAN 24 2015/ DRY NORTHWEST FLOW ALOFT WILL REMAIN OVER NORTH TEXAS THROUGH MONDAY AS A HIGH AMPLITUDE RIDGE BUILDS ACROSS THE WESTERN HALF OF THE NATION AND A TROUGH DEEPENS ACROSS THE EAST. A SHORT WAVE TROUGH WILL TRANSLATE SOUTHEAST ACROSS THE NORTHERN AND CENTRAL PLAINS TONIGHT AND ALLOW A COLD FRONT TO MOVE SOUTH ACROSS THE CENTRAL PLAINS. WE WILL HOLD OFF ON ISSUING A WIND ADVISORY FOR NOW SINCE WINDY CONDITIONS SHOULD BE SHORT LIVED AND ON THE LOW END OF ADVISORY CRITERIA. AFTERNOON HIGHS SUNDAY WILL STILL BE A BIT WARMER THAN TODAY. THE BREEZY CONDITIONS WILL MAKE IT FEEL A BIT COOLER.
OTHERWISE CDFNT/TROF OVER CENTRAL PLAINS WILL CONTINUE TO HEAD TOWARDS THE TN VALLEY TONIGHT. MID/HIGH CLOUDS WILL BEGIN TO SPREAD ACROSS THE TN VALLEY OVERNIGHT AS AN UPPER LOW/CDFNT APPROACHES THE CWA.
Mostly sunny skies during the morning hours will give way to partly cloudy skies during the afternoon as a cold front approaches from the northwest. Afternoon high temperatures will likely reach the lower to middle 60s across the area.
358 AM EST SUN JAN 25 2015 LOW PRESSURE WILL BRING WIDESPREAD SNOW LATER TODAY THROUGH MONDAY. BROAD UPR TROFG IS PROGGED TO BEGIN TO SHIFT E OF THE RGN TUE WITH DCRG SNW SHWR CHCS.
WATER VAPOUR SHOWED UPPER RIDGE OVER WESTERN NORTH AMERICA. EVOLUTION OF THIS UPPER RIDGE WILL DRIVE SHORT TERM WEATHER. UPPER RIDGE WILL BUILD INTO THE NORTHERN PLAINS THROUGH MONDAY NIGHT. THERMAL RIDGE WILL DEVELOP AND INTENSIFY AS DOWNSLOPE FLOW ENHANCES DEVELOPING LEE TROUGH FROM CENTRAL MT INTO CENTRAL NE.
STRONG HIGH PRESSURE WILL BUILD INTO THE WESTERN STATES SUNDAY AND MONDAY.
WITH TEMPERATURES WELL ABOVE FREEZING IN THE LOW LEVELS. MOST LIKELY WE WILL SEE A WET SNOW WITH A HIGH COMPACTION RATE GIVEN PROFILE TEMPERATURES CLOSE TO THE FREEZING MARK. GUIDANCE GIVES BETWEEN 1 AND 3 INCHES AND WILL HEDGE TOWARDS THE LOWER END OF THE SPECTRUM. WEAK HIGH PRESSURE MOVES OVERHEAD MONDAY NIGHT.
SOUTHWEST FLOW AROUND THE LOW ACROSS THE AREA. A LITTLE MORE SUNSHINE IS EXPECTED ON SATURDAY AS LOW LEVEL CLOUDS ARE EXPECTED TO SCATTER OUT BY AFTERNOON WITH MORE OF A WESTERLY WIND IN THE LOW LEVELS TO BRING IN SOME DRIER AIR.
356 PM CDT FRI MAR 13 2015 MAIN FORECAST CHALLENGE IN THE SHORT-TERM IS THE POTENTIAL FOR FREEZING PRECIPITATION IN THE ARROWHEAD TONIGHT AND HIGH TEMPERATURES ON SATURDAY. LATE THIS AFTERNOON SEVERAL VORT MAXES WERE ROTATING SOUTHEASTWARD AROUND THE BASE OF AN UPPER-LEVEL TROUGH. RAIN/DRIZZLE OR FREEZING RAIN/DRIZZLE ARE THE MOST LIKELY PTYPES OVERNIGHT. THERE IS A SLIGHT CHANCE OF DRIZZLE OR FREEZING DRIZZLE IN THE NORTHEAST BEFORE NOON. TEMPERATURES WILL TOP OUT IN THE LOW 40S AT THE TIP OF THE ARROWHEAD AND IN IRON COUNTY. A POSITIVELY TILTED UPPER RIDGE WILL BE OVER THE FORECAST AREA SATURDAY NIGHT. UNDERNEATH THE RIDGE WILL BE A STIFF SW FLOW ALOFT.
102 PM EDT FRI MAR 13 2015 CANADIAN HIGH PRESSURE WILL BUILD ACROSS THE REGION TODAY AND WILL AND PASS TO THE SOUTHEAST TONIGHT.
227 PM CDT FRI MAR 13 2015 SURFACE ANALYSIS SHOWS A WEAK TROUGH OF LOW PRESSURE ACROSS THE FORECAST AREA EARLY THIS MORNING. THE TROUGH HAS BEEN WEAKENING AS IT DRIFTS TO THE EAST THROUGH THE NIGHT. THE RELATIVE HUMIDITIES WILL BE A LITTLE HIGHER THAN YESTERDAY WITH THE LOWER TEMPERATURES AND DEW POINTS A LITTLE HIGHER.
THAT DISTURBANCE IS FORECAST TO PHASE WITH THE NORTHERN STREAM AND RESULT IN AN EASTERN CANADIAN CLOSED LOW. AND COLD FRONT PASSAGE FOR THE THE UPPER OHIO ON SATURDAY.
WRAPPING AROUND THE DEEP LAYER LOW PRESSURE SYSTEM.
ESPECIALLY ALONG THE HIGHER ELEVATIONS. ESPECIALLY ALONG THE HIGHER ELEVATIONS. STRONG SOUTH TO SOUTHWEST PRESSURE GRADIENTS WILL INCREASE TOMORROW RESULTING IN SOME BREEZY CONDITIONS IN THE LOWER COLUMBIA BASIN AHEAD OF THE INCOMING WEATHER SYSTEM MIDDAY SATURDAY. PRECIPITATION FORECAST TRENDS WITH INCOMING MODEL GUIDANCE INDICATES THAT THE LOWER COLUMBIA BASIN AND LOCATIONS IMMEDIATELY ON THE LEE OF THE CASCADES MAY RECEIVE LESS PRECIPITATION THAN PRESENTLY FORECAST.
200 PM PDT FRI MAR 13 2015 STRONG HIGH PRESSURE ALOFT WILL BRING WELL ABOVE AVERAGE HIGH TEMPERATURES THROUGH THE WEEKEND.
TAF SITES REMAIN NEAR THE WESTERN PERIPHERY OF THE CLOUD SHIELD ASSOCIATED WITH A MEANDERING UPPER LOW. THE LOW PRESSURE SYSTEM OVER NORTHEAST TEXAS IS DISPLAYING SOME WARM-CORE CHARACTERISTICS AS IT DRIFTS NORTHWARD. RAIN COVERAGE WILL LIKELY DIMINISH DURING THE AFTERNOON HOURS AS DIFFERENTIAL HEATING DISRUPTS THE MECHANISM FOR SUSTAINED BROAD SCALE LIFT NEAR THE CENTER OF THE LOW. /ISSUED 337 AM CDT FRI MAR 13 2015/ A WELL DEFINED UPPER TROUGH EXTENDING FROM WEST OF HOUSTON INTO THE NORTHERN GULF EARLY THIS MORNING WILL TRACK NNE ACROSS EAST TEXAS AND LOUISIANA TODAY. RAIN CHANCES WILL BEGIN DIMINISHING FROM SOUTHWEST TO NORTHEAST BY TONIGHT AS THE FORCING FROM THE UPPER TROUGH MOVES EAST OF THE AREA.
The same ribbon of dry air that has been residing within the ridge axis will mix down to the surface today lowering dew points into the 30s for most locations. The day time temperatures and low dew points yield minimum RH values in the low to mid 20 percent range. Despite incoming cooler air mass for Saturday, temperatures still manage to mix out into the 60s as the high moves over and winds diminish through the day.
320 PM PDT FRI MAR 13 2015 HIGH PRESSURE OVER THE SOUTHWEST U.
NORTHWEST TO WEST AROUND THE BACK SIDE AND IN WAKE OF THE TROUGH OF LOW PRESSURE/COLD FRONT.
Low temperatures will be mild, in the low to mid 60s.
1251 PM MDT FRI MAR 13 2015 UPPER RIDGE AXIS CURRENTLY OVER THE NORTHERN ROCKIES WILL BUILD SOUTHEASTWARD THROUGH SATURDAY. WINDS WILL BE LIGHT UNDER THE RIDGE.
HIGH PRESSURE WILL SLOWLY GIVE WAY TO A COLD FRONT APPROACHING FROM THE WEST ON SATURDAY.
DESPITE THE SLOW MOISTENING OF THE LOWER ATMOSPHERE. THE LOWER LEVELS WILL REMAIN SATURATED SUCH THAT THERE WILL BE SOME MIST IN WITH THE RAINFALL BUT NOT EXPECTING ANYTHING ENOUGH TO DROP VIS BELOW A MILE OTHER THAN ANY ISOLATED OCCURRENCES OF HEAVY RAIN DROPPING VIS. THERE MAY BE ENOUGH DAY TIME HEATING AND WAA INTO SOUTHEASTERN KENTUCKY FOR A SLIGHT CHANCE OF THUNDER AHEAD OF THE COLD FRONT. COOLER AIR AND SUBSIDENCE MOVING IN BEHIND THE FRONT ON SATURDAY NIGHT WILL BE ENOUGH FOR SOME DENSE FOG DEVELOPMENT ACROSS THE AREA.
502 PM EDT FRI MAR 13 2015 FRONT PUSHES NORTH AS A WARM FRONT TONIGHT. THEN BACK SOUTH AS COLD FRONT SATURDAY.
1237 PM CDT FRI MAR 13 2015 SURFACE ANALYSIS SHOWS A WEAK TROUGH OF LOW PRESSURE ACROSS THE FORECAST AREA EARLY THIS MORNING. THE TROUGH HAS BEEN WEAKENING AS IT DRIFTS TO THE EAST THROUGH THE NIGHT. THE RELATIVE HUMIDITIES WILL BE A LITTLE HIGHER THAN YESTERDAY WITH THE LOWER TEMPERATURES AND DEW POINTS A LITTLE HIGHER.
WARM FRONT HAD LIFTED TO JUST NORTH OF THE FL/GA LINE AT 18Z. NORTH OF THE WARM FRONT A FEW SHOWERS CAN BE EXPECTED. SOUTH OF THE WARM FRONT THE AIRMASS HAS DESTABILIZED. WITH COLD FRONT APPROACHING FROM THE WEST.
213 PM EDT FRI MAR 13 2015 HIGH PRESSURE DRIFTING EASTWARD OVER THE ATLANTIC SEABOARD WILL CONTINUE TO PROVIDE GENERALLY DRY CONDITIONS TO THE NORTH COUNTRY TODAY WITH A FEW FLURRIES OR SNOW SHOWERS POSSIBLE ALONG THE INTERNATIONAL BORDER.
524 PM CDT FRI MAR 13 2015 LATEST REGIONAL MOSAIC RADAR SHOWS THAT THE HEAVY RAIN AXIS ALONG THE WARM FRONT HAS LIFTED WELL NWD.
151 PM EDT FRI MAR 13 2015 AVIATION FAIR AND MILD WEATHER WILL CONTINUE TODAY WITH HIGH TEMPERATURES REACHING THE LOWER TO MIDDLE 50S. A COLD FRONT WILL BRING A FEW LIGHT RAIN SHOWERS INTO EXTREME SOUTHERN LOWER MICHIGAN TONIGHT. FAIR WEATHER WILL CONTINUE TODAY WITH PARTLY CLOUDY SKIES AND SOUTHERLY WINDS THAT WILL HELP TO BOOST MAX TEMPS INTO THE LOWER TO PERHAPS MIDDLE 50S. A CONSENSUS OF LATEST SHORT RANGE GUIDANCE CONTINUES TO SUGGEST THAT MOST IF NOT ALL RAIN ASSOCIATED WITH THE WEAK LOW AND COLD FRONT TONIGHT SHOULD STAY SOUTH OF LWR MI. A SLIGHTLY COOLER AIRMASS WILL ADVECT IN ON NW WINDS BEHIND THAT SYSTEM SATURDAY.
A LENGTHY AND HEFTY RIDGE AXIS IS ALIGNED FROM THE NEW ENGLAND COAST DOWN THE EASTERN SEABOARD.
1220 PM CDT FRI MAR 13 2015 MAIN CONCERNS TODAY WILL BE PATCHY EARLY MORNING FOG OVER THE EAST AND COLD FRONT MOVING INTO THE REGION ACROSS THE NORTHWEST DURING THE MORNING HOURS. A FEW SHOWERS ASSOCIATED WITH THE LOW OVER THE SOUTHERN PLAINS WILL MOVE TOWARD THE FAR SOUTHEAST THIS MORNING. AS THE COLD FRONT MOVES ACROSS THE REGION THIS AFTERNOON NW WINDS WILL INCREASE AND DEW POINTS WILL LOWER.
215 PM MDT FRI MAR 13 2015 UPPER RIDGE AXIS CURRENTLY OVER THE NORTHERN ROCKIES WILL BUILD SOUTHEASTWARD THROUGH SATURDAY. WINDS WILL BE LIGHT UNDER THE RIDGE.
A COLD FRONT THAT PUSHED ACROSS THE AREA EARLY THIS MORNING HAS MOVED SOUTH OF THE TEXAS PANHANDLE. THE MAIN AVIATION CONCERN WILL BE A COLD FRONT POISED TO TRAVERSE THE PANHANDLES THIS MORNING. /ISSUED 430 AM CDT FRI MAR 13 2015/ WEAK COLD FRONT WILL BRING SLIGHTLY COOLER CONDTIONS TO THE TEXAS AND OKLAHOMA PANHANDLES TODAY.

NORTH-CENTRAL AND NORTHEAST COLORADO WILL REMAIN UNDER WEAK NORTHERLY FLOW THROUGH THE NEXT 24-36 HOURS AS THE UPPER RIDGE AXIS DROPS OVER COLORADO. DRIER AND WARMER CONDITIONS WILL PREVAIL THROUGH SATURDAY AS THE UPPER RIDGE STRENGTHENS OVER THE STATE. SATURDAY AFTERNOON TEMPERATURES SHOULD BE 5-10 DEGREES WARMER THAN THIS AFTERNOON. UPPER LEVEL RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE REGION THROUGH THE WEEKEND.
319 PM EDT FRI MAR 13 2015 LOW PRESSURE WILL MOVE IN FROM THE SOUTHWEST ON SATURDAY.
A WEAK LOW PRESSURE SYSTEM WILL BRING A CHANCE OF RAIN SHOWERS IN EASTERN ARIZONA THROUGH EARLY THIS EVENING.
HIGH PRESSURE SHOULD BREAK DOWN OVER SOUTHERN IDAHO SAT NIGHT AS A MOIST SUBTROPICAL AIR MASS ENTRAINED INTO A FAIRLY VIGOROUS TROUGH BRINGS A WARM RAIN EVENT INTO CENTRAL IDAHO.
347 PM CDT FRI MAR 13 2015 UPPER LEVEL RIDGE OVER THE ROCKIES WILL SHIFT OVER THE RED RIVER VALLEY ON SAT. UPPER LEVEL TROUGH OVER THE GULF OF AK WILL MOVE INTO NORTHERN CANADA. COOLER WEATHER WILL MOVE OUT OF CANADA SUN NIGHT/MON MORNING. COLD FRONT WILL MOVE OUT OF CANADA SUN NIGHT/MON MORNING.
TEMPERATURES HAVE JUMPED INTO THE LOWER AND MIDDLE 70S ACROSS AREAS RECEIVING SUNSHINE. MAIN UPPER TROF WILL REMAIN STATIONARY FROM MISSOURI THROUGH TEXAS TO OFF THE TIP OF BAJA CALIFORNIA. THE UPPER LOW WILL CUT OFF AGAIN OFF THE SOUTHERN TIP OF BAJA CALIFORNIA.
306 PM CDT FRI MAR 13 2015 MID/UPPER LEVEL LOW RESPONSIBLE FOR THE LOW CLOUDS AND RAIN THE PAST FEW DAYS HAS FINALLY EJECTED AWAY FROM THE AREA AND IS LOCATED OVER THE ARKLATEX REGION THIS AFTERNOON. AREA OF LOW PRESSURE IS PERSISTING OVER MEXICO AND THIS WILL KEEP SOME CLOUDS AND UNSETTLED WEATHER IN THE FORECAST FOR THE END OF THE WEEKEND INTO MID WEEK. THIS BOUNDARY WILL GENERALLY LOSE DEFINITION OVERNIGHT AND INTO SATURDAY AS ONSHORE FLOW RETURNS IN ADVANCE OF MID/UPPER LOW OVER NRN MEXICO.
LIFR CIGS ARE EXPECTED TO TRANSITION TO MVFR AND EVENTUALLY VFR BY THIS EVENING AS A PESKY AREA OF LOW PRESSURE NEAR KSHV MOVES NORTH AND AWAY FROM THE AREA.
320 PM CDT FRI MAR 13 2015 CURRENT WATER VAPOR IMAGERY SHOWS THE BROAD UPPER LEVEL LOW CURRENTLY SITUATED ACROSS THE ARKLATEX. WITH UPPER LEVEL RIDGING ACROSS THE WEST COAST AND ACROSS THE FAR SOUTHEASTERN STATES. LOW PRESSURE WAS CONTINUING TO MOVE SLOWLY ACROSS CENTRAL ARKANSAS. WITH A WEAK COLD FRONT EXTENDING SOUTHWARD THROUGH EASTERN LOUISIANA. HIGH PRESSURE SETTLING ON THE LEEWARD SIDE OF THE APPALACHIANS WAS PRODUCING EASTERLY WINDS ACROSS THE FORECAST AREA. THE AFOREMENTIONED COLD FRONT WILL APPROACH THE FORECAST AREA.
A BROAD/LARGE UPPER LOW DRAPED ACROSS THE SRN U. MODELS PROG MID/UPPER LEVEL MOISTURE TO DEEPEN OVERNIGHT BUT THE LOWER LEVELS ARE PROGD TO REMAIN FAIRLY DRY. AND A WEAK COLD FRONT IS ALSO PROGD TO MOVE S INTO THE CWA DURING THE DAY. AS FOR THE COLD FRONT SAT.
231 PM EDT FRI MAR 13 2015 A WARM FRONT JUST SOUTH OF THE FORECAST AREA WILL LIFT NORTH OF THE AREA EARLY SATURDAY. AN APPROACHING COLD FRONT WILL MOVE THROUGH THE REGION LATE SATURDAY NIGHT.
341 PM MDT FRI MAR 13 2015 DRY AND QUITE MILD CONDITIONS WILL SETTLE OVER THE CWA THROUGH THE WEEKEND AS AN UPPER RIDGE NOSES ACROSS THE AREA.
358 PM CDT Fri Mar 13 2015 Lastest northward surge of moisture around the periphery of upper low will fall short of reaching the far southeast corner of the county warning area.
AN UPPER LEVEL LOW OVER NORTEAST TEXAS CONTINUES TO PUSH TO THE NORTHEAST WHILE ANOTHER UPPER LEVEL LOW FEATURE SITS ACROSS CENTRAL TEXAS. OVERNIGHT LOWS WILL RANGE FROM THE MID 40S TO THE MID 50S WITH SATURDAY'S HIGH TEMPS IN THE LOWER 70S MOST AREAS.
A band of mid level clouds will follow a cold front through the area late tonight and Saturday morning, with ceilings at 7k to 10k feet.
1024 AM PDT FRI MAR 13 2015 Today will see record warm temperatures returning to the Inland Northwest care of a strong upper level ridge. The ridge will exit the area tonight allowing a very wet weather system to move in from the southwest. Current 24-hour change in temperatures still shows us cooler than yesterday at this time, but this is due to a much cooler start.
145 PM EDT FRI MAR 13 2015 A LOW PRESSURE SYSTEM OVER THE WESTERN GULF OF MEXICO WILL MOVE NORTH INTO ARKANSAS TODAY. HIGHS THIS AFTERNOON WILL RANGE IN THE LOW TO MID 50S. THESE FEATURES WILL DROP SEVERAL TRAILING COLD FRONTS THROUGH THE AREA RESULTING IN A VARIABLE TEMP REGIME.
SCHULTZ THE FORECAST FOR TODAY IS ON TRACK FOR HIGHS IN THE 60S F AND SOME RELATIVELY LIGHT WINDS AS 500-MB RIDGING BUILDS ACROSS THE REGION. AN UPPER RIDGE WILL BUILD INTO THE REGION TODAY AND PROVIDE ABUNDANT SUNSHINE. LIGHTER WINDS AND LESS CLOUD COVER OVERNIGHT WILL PROVIDE A COOLER START THIS MORNING. EXPECTING A SLIGHTLY COOLER DAY TODAY DUE TO THIS ALONG WITH WEAK MIXING. THIS EVENT WILL QUICKLY DEVELOP A LEE TROUGH AND INCREASE WINDS OVER THE WESTERN VALLEYS. THIS WILL DRY OUT THE LOW LEVELS AND CAUSE DEWPOINTS TO FALL BACK INTO THE LOWER TO MID 20S. DEWPOINTS IN THE LOWER TO MID 20S WILL PRODUCE HUMIDITIES IN THE TEENS.
15Z/10 am surface map shows 1014 mb low pressure near the TX/OK/LA/AR border while a warm front extended ne to along the MS/OH rivers. Low pressure to move ne across AR this afternoon and tonight while bringing another area of moderate to heavy rain into southeast IL especially later this afternoon and evening, then diminishing from the nw later tonight into Saturday morning. Warmer temps expected in the northwest where fewer clouds and no pcpn is forecasted. Cooler temps will be in the east and south where more clouds and pcpn will be. High pressure will build into the Midwest and has previously resulted in a dry forecast with warm temperatures through the weekend.
THE WINDS WILL REMAIN GUSTY AT THE HIGHER ELEVATIONS. WINDS WILL BE EXPECTED TO LIGHTEN BY THE AFTERNOON TOMORROW ONCE THE LOWER LEVEL JET MOVES THROUGH. A COLD FRONT WILL DROP THROUGH THE SOUTHERN APPALACHIAN REGION ON SATURDAY NIGHT.
236 PM EDT FRI MAR 13 2015 FRONT PUSHING NORTH AS A WARM FRONT TODAY AND TONIGHT. AND THEN BACK SOUTH AS COLD FRONT SATURDAY.
/ISSUED 511 AM CDT FRI MAR 13 2015/ MEAN TROF REMAINS ANCHORED OVER THE SOUTHERN PLAINS AND NORTHERN MEXICO. MORE ISOLATED/SCATTERED PATCHES OF RAIN STILL ARE STILL POSSIBLE THIS AFTERNOON IN THE WRAP-AROUND REGION OF THE EXITING UPPER TROF. WILL CONTINUE PLUNGING INTO THE BACKSIDE OF THE MEAN TROF OUT WEST.
1229 PM CDT FRI MAR 13 2015 ANOTHER UNSEASONABLY WARM DAY IS ON TAP FOR THE REGION AHEAD OF A WEAK COLD FRONT MARCHING SOUTHEAST ACROSS THE NORTHERN PLAINS. THIS WAVE WILL PUSH EAST TODAY DRIVING THE COLD FRONT ACROSS THE REGION. HIGH PRESSURE BUILDS IN TONIGHT INTO SATURDAY.
1227 PM CDT Fri Mar 13 2015 Scattered rain showers continue to stream north across the region, ahead of an approaching upper level low currently centered over southeastern Texas.
225 PM CDT Fri Mar 13 2015 An expansive, but weak, upper trough over the region will result in mainly quiescent weather conditions the next few days. The northern stream will sweep the northern extent of the broad ua trough eastward, and allow a weak cold front to drop through the region tonight and Saturday, but only with a minimum of cooling. The cutoff low will meander southward through late this weekend, before another ua trough approaches the west coast and provides the impetus for the cutoff upper low ejecting northeastward over the region.
AN UPPER LEVEL LOW AND FRONTAL LOW PRESSURE SYSTEM. EXTENDING SOUTHEAST OF THE LOW.
WINDS AT KJBR BECOMING NORTHERLY 7 KTS AFTER 14Z/12Z WITH PASSAGE OF A COLD FRONT.
336 PM EDT FRI MAR 13 2015 A LOW PRESSURE SYSTEM MOVING THROUGH THE OHIO VALLEY WILL BRING A CHANCE OF RAIN TO AREAS ALONG AND SOUTH OF HIGHWAY 24 TONIGHT. HIGH PRESSURE WILL THEN RETURN TO THE REGION TOMORROW. LOWS TONIGHT WILL BE IN THE LOWER 40S WITH HIGHS ON SATURDAY AROUND 50 DEGREES. OVERNIGHT LOWS WILL REMAIN IN THE LOW 40S GIVEN ABUNDANT CLOUDS. UPPER TROUGH WILL BE MOVING SOUTH ACROSS THE REGION SATURDAY NIGHT.

WARM DRY HIGH PRESSURE WILL BUILD ACROSS THE GREAT BASIN TODAY THROUGH THE WEEKEND. A RIDGE CONTINUES TO BUILD INTO THE GREAT BASIN THIS AFTN WITH THE CWA UNDER NELY FLOW WITH SOME RESIDUAL MOISTURE GENERATING A FEW STRATOCUMULUS OVER THE CENTRAL AND SRN MTNS. THE RIDGE CONTINUES TO SLOWLY BUILD OVER THE GREAT BASIN TONIGHT AND SAT WITH CONTINUED GRADUAL AIRMASS AND SURFACE WARMING. YET MORE WARMING IS FORECAST FOR SUN AS THE RIDGE SHIFTS EAST A BIT AND SWLY FLOW PICKS UP. THIS WAVE COULD STILL SEND SOME SLIGHTLY COOLER AIR INTO NRN UT AT LOW LEVELS LATE SUN INTO MON BUT THE LATEST 18Z NAM HAS FALLEN IN LINE WITH THE EC AND NOW KEEPS THIS BOUNDARY NORTH OF SLC UNTIL MON MORNING UNLIKE THE 12Z RUN.
345 PM CDT Fri Mar 13 2015 (Tonight and Saturday) Large upper level trough axis remains parked across the Southern Plains late this afternoon. Embedded Upper level low is drifting north into Oklahoma. Stronger northerly flow on its back side will aid the push of a cold front into West Central Texas late tonight and early Saturday. Most of the rain would be closer to the upper low itself across north Texas and southern Oklahoma, but GFS shows a little as far southwest as the Big Country and Heartland. More cloud cover tonight will keep temperatures a little warmer, with readings Saturday afternoon just a degree or two cooler than what we are looking at for today. A closed low developing over western Mexico will drop south off the west coast of Mexico overnight and Saturday.
151 PM CDT FRI MAR 13 2015 SURFACE ANALYSIS SHOWS A WEAK TROUGH OF LOW PRESSURE ACROSS THE FORECAST AREA EARLY THIS MORNING. THE TROUGH HAS BEEN WEAKENING AS IT DRIFTS TO THE EAST THROUGH THE NIGHT. THE RELATIVE HUMIDITIES WILL BE A LITTLE HIGHER THAN YESTERDAY WITH THE LOWER TEMPERATURES AND DEW POINTS A LITTLE HIGHER.
WATER VAPOR IMAGERY SHOWS UPPER LOW NEAR THE CONJUNCTION OF SOUTHERN SONORA. A SNAPSHOT OF THE SYNOPTIC SITUATION ALSO SHOWS A VORT MAX IN THE VICINITY OF CENTRAL TEXAS WITH AN ASSOCIATED TROUGH AXIS EXTENDING EASTWARD ACROSS NORTHERN LOUISIANA AND CENTRAL MISSISSIPPI. HIGH PRESSURE RESIDES OVER THE EASTERN PACIFIC WATERS. MODELS INDICATE THAT THE AFOREMENTIONED UPPER LOW WILL CONTINUE TO MOVE FARTHER SOUTH BEYOND THE SOUTHERN GULF OF CALIFORNIA THROUGH EARLY SATURDAY. AS THIS OCCURS THE RIDGE OVER THE EASTERN PACIFIC WILL LINGER WITH THE ASSOCIATED RIDGE AXIS EXTENDING ACROSS CENTRAL CALIFORNIA INTO THE GREAT BASIN.
650 PM EDT FRI MAR 13 2015 LOW PRESSURE WILL MOVE IN FROM THE SOUTHWEST ON SATURDAY.
