LATEST WATER VAPOR IMAGERY SHOWS THE UPPER LOW NEAR THE BIG BEND REGION THIS AFTERNOON. DEEP LAYER SOUTH TO SOUTHWEST FLOW ALOFT ASSOCIATED WITH THIS FEATURE AND ABUNDANT MID LEVEL MOISTURE CONTINUES TO STREAM OVER THE REGION THIS AFTERNOON AS THE UPPER LOW CONTINUES TO EJECT NORTHEAST TOWARDS WEST TEXAS. A WEAK COLD FRONT DRAPED ACROSS THE EXTREME SOUTHEASTERN PORTIONS OF THE CWA/MSA. EXTENDING FROM EAST OF BROWNSVILLE TO SOUTH PADRE ISLAND ACROSS THE NORTHEAST SECTIONS OF THE LOWER TEXAS GULF WATERS THIS AFTERNOON. THE TROUGH MOVE EAST OF THE REGION ON SUNDAY WITH IMPROVING CONDITIONS AS DRIER AIR FILTERS INTO DEEP SOUTH TEXAS. WHICH IS WARMER THAN SUPERBLEND AND CLOSER TO MAV/MET NUMBERS.
149 PM EDT SAT MAR 21 2015 A WARM FRONT WILL LIFT NORTH OF THE REGION THIS AFTERNOON WITH A FEW RAIN AND SNOW SHOWERS. A COLD FRONT WILL QUICKLY FOLLOW THE WARM FRONT AND CROSS THE REGION LATE THIS AFTERNOON AND EVENING.
THIS EVENING THROUGH SUNDAY NIGHT CURRENT SURFACE MAP SHOWS HIGH PRESSURE RIDGE ACROSS MINNESOTA. WITH TROF ACROSS CENTAL MONTANA INTO WYOMING.
342 PM CDT SAT MAR 21 2015 UPPER LOW HAS MOVED INTO WEST TEXAS. COLD FRONT NEAR A MCCOMB TO NEW ROADS LINE AT 3 PM. ALLOWING TEMPERATURES TO REACH THE LOWER 80S IN MANY AREAS. UPPER LOW WILL CONTINUE TO MOVE NORTHEAST AND WEAKEN AS IT MOVES ACROSS THE LOWER MISSISSIPPI RIVER VALLEY THROUGH SUNDAY.
SHORT TERM: (Through Late Tonight) A cold front will sink southward and stall tonight, eventually becoming quasistationary across the region.
UPPER LEVEL ANALYSIS PLACES RIDGE OVER EASTERN MONTANA UP INTO SASKATCHEWAN/ALBERTA WHILE DEEP LOW SPINS NEAR JAMES BAY BRINGING NORTHWEST FLOW TO OUR AREA. SHORT WAVE WILL PUSH ITS WAY OVER THE RIDGE. FORECAST SOUNDINGS SUGGEST THE POSSIBILITY OF A LITTLE SLEET OF FREEZING RAIN MAINLY OVER THE FAR WEST SO HAVE ADDED A MENTION OF THAT. TOTAL SNOW AMOUNTS FROM THIS SYSTEM STILL LOOK TO BE THE HIGHEST MAINLY OVER NORTH CENTRAL NORTH DAKOTA INTO PARTS OF THE NORTHWEST.
SFC TEMPS LOOK TO BE SUB FREEZING BY THIS TIME. MAKING FREEZING RAIN/DRIZZLE THE PCPN TYPE.
351 PM CDT SAT MAR 21 2015 MID-AFTERNOON SFC ANALYSIS SHOWS AN AREA OF LOW PRESSURE DEVELOPING OFF THE UPPER TX COAST WITH A NEARLY STATIONARY FRONT EXTENDING ENEWD TO THE SWRN LA COASTLINE AND SERN LA. ALTHOUGH BEST POPS SHOULD EVENTUALLY SHIFT TOWARD THE NRN PORTIONS OF THE AREA AS THE LOW/BOUNDARY DRIFT INLAND TONIGHT.
138 PM EDT SAT MAR 21 2015 WEAK HIGH PRESSURE OVER THE AREA TODAY WILL ENSURE MILD TEMPERATURES AND DRY WEATHER.
A LOW AMPLITUDE RIDGE WILL REMAIN IN PLACE THROUGH THE END OF THE WEEKEND.
WILL LIKELY BE A FACTOR HOLDING OFF INITIATION UNTIL LATE AFTN BEFORE EXPANDING ACROSS ERN AND SRN PORTIONS OF THE CWA ALONG ANTICIPATED COLD FRONT DURING THE EVENING HOURS.
350 PM EDT SAT MAR 21 2015 A COLD FRONT WILL BE MOVING SOUTHWARD ACROSS THE REGION TODAY. HIGH TEMPERATURES WILL RANGE FROM THE MIDDLE 40S NEAR LAKE MICHIGAN TO THE LOWER 60S ALONG THE OHIO RIVER. HIGH PRESSURE WILL BUILD INTO THE REGION TONIGHT RESULTING IN MOSTLY CLEAR SKIES.
345 PM CDT Sat Mar 21 2015 (Tonight and Sunday) As of mid afternoon, the upper low was located near Fort Stockton and will lift northeast across the area this evening. Carrying highest POPs across central and northern counties this evening and across northern counties after midnight, where models show some wrap around precipitation developing on the back side of the upper low. Pleasant weather returns to the area on Sunday, with dry and warmer weather expected. Mostly cloudy skies in the morning will give way to mostly sunny skies by afternoon with highs in the lower and middle 70s. 24 (Sunday Night through Saturday) Winds aloft over the forecast area will remain essentially zonal into mid-week in the wake of the departing upper trough with dry conditions prevailing.
TODAY THROUGH SUNDAY NIGHT CURRENT SURFACE MAP SHOWS COLD HIGH PRESSURE OVER THE EASTERN DAKOTAS WITH A LOW PRESSURE TROUGH DEEPENING TO THE EAST OF THE ROCKIES. THE UPPER ANALYSIS SHOWS AN UPPER LEVEL RIDGE BUILDING OVER THE NORTHERN PLAINS. THE UPPER RIDGE WILL REBOUND OVER THE NRN PLAINS ON SUNDAY.
157 PM EDT SAT MAR 21 2015 A COLD FRONT FROM SOUTHWEST ONTARIO THROUGH SOUTHERN LOWER MICHIGAN WILL MOVE SOUTHEAST ACROSS THE AREA THIS AFTERNOON.
THE LOW CLOUDS THIS MORNING HAVE CLEARED OUT WITH SOME LOCATIONS SEEING PEEKS OF SUNSHINE BEFORE THE MID AND HIGH CLOUDS MOVED IN. CLOUDS WILL CONTINUE TO LINGER BUT BREAKS ARE POSSIBLE AS THE LOWER LEVELS ARE DRY. DID NOT ADJUST THE HIGH TEMPS AT THIS TIME. THERE HAS BEEN VIRGA IN NW AL DOWN TO CULLMAN BUT THE LOWER LEVELS ARE JUST TOO DRY AT THIS TIME.
A WEAK DISTURBANCE IS CURRENTLY SHIFTING SOUTHEAST AWAY FROM SOUTHERN COLORADO AND HIGH PRESSURE OVER THE INTERMOUNTAIN WEST IS BUILDING INTO THE ROCKIES. CONTINUED WITH THE LOW POPS IN THOSE AREAS HOWEVER CONFIDENCE IN OCCURRENCE IS LOW. THE UPPER LEVEL HIGH WILL SHIFT TO THE CENTRAL PLAINS DURING THE DAY ON SUNDAY WITH BROAD SOUTHWEST FLOW MOVING ACROSS THE REGION BY THE AFTERNOON. THEN COOLER WITH RAIN AND SNOW POSSIBLE.
ALOFT, RIDGING WILL CONTINUE ACROSS THE ROCKIES AND EXTENDING OUT ACROSS THE PLAINS. AT THE SURFACE, A LEE TROUGH WILL CONTINUE WITH SLIGHT POSITIONAL ADJUSTMENTS FROM TODAY AND INTO TOMORROW. HERE, THE LEE TROUGH WILL BE LOCATED WITH RESULTANT WEAKER WINDS. RELATIVE HUMIDITIES ACROSS FAR WESTERN KANSAS WILL APPROACH OR REACH 15 PERCENT, HOWEVER, WEAKER WINDS ARE EXPECTED IN ASSOCIATION WITH THE LEE TROUGH. A WEAK COLD FRONT MOVES ACROSS WESTERN KANSAS SUNDAY NIGHT WITH SOUTH WINDS SHIFTING TO THE NORTHEAST AT 10 TO 15 MPH.
232 PM EDT SAT MAR 21 2015 WEAK HIGH PRESSURE BUILDS IN FROM THE WEST TODAY IN WAKE OF DEPARTING LOW PRESSURE. HIGH PRESSURE DRIFTS OFF THE COAST SATURDAY. A WEAK COLD FRONT PUSHES THROUGH THE AREA SUNDAY NIGHT.
TWEAKED SUNDAYS HIGHS TOWARD THE NAM MOS WHICH IS A LITTLE COOLER IN THE NORTHEAST.
Despite a cold front that moved through the area earlier today, the lack of cold air advecting into the area behind the front has allowed conditions to remain mild this afternoon. Out ahead of the cold front winds will veer to the south east across the area. Couple that with height rises across the area and highs will reach into the low 60s across the northeastern CWA to the mid 70s across the western CWA.
A COLD FRONT WILL MOVE INTO THE AREA ON SUNDAY. WEAK HIGH PRESSURE OVER NW CAL HAS BROUGHT A GENERALLY FAIR DAY TO THE REGION. THIS HIGH WILL SHIFT OUT OF THE AREA THIS EVENING AND OVERNIGHT AS LOW PRESSURE DIGS IN FROM THE NW. A WEAK SURFACE BOUNDARY TRYING TO UNDERCUT THE WEAK RIDGE THIS AFTERNOON WILL BRING INCREASING CLOUD COVER TO MENDOCINO COUNTY EARLY THIS EVENING THEN ACROSS THE ENTIRE REGION OVERNIGHT. WITH SUCH A LOW CHANCE, HAVE CONFINED ANY MENTION OF SHOWERS TO THE HIGHEST PEAKS AND OVERNIGHT. THIS ALONG WITH HIGH CLOUDS AHEAD OF THE NEXT COLD FRONT WILL BRING MOSTLY CLOUDY CONDITIONS TO NW CAL TONIGHT.
GIVEN THE LOW DEW POINTS AND LACK OF ANYTHING SIGNIFICANT SO FAR. WHICH MAKES SENSE GIVEN THE DRYNESS OF THE LOWER LAYERS OF THE ATMOSPHERE. SFC RIDGING WILL BE IN PLACE ACROSS THE REGION WITH A COUPLE WEAK WAVES INDUCING FRONTOGENESIS AND BANDS OF SNOW. SIMILAR SCENARIO ALTHOUGH THE RIDGING WILL BE SHIFTED SLIGHTLY EAST AND SYNOPTIC SUPPORT IS SLIGHTLY STRONGER.
152 PM EDT SAT MAR 21 2015 A COLD FRONT WILL PASS THROUGH THE REGION THIS AFTERNOON AND EARLY EVENING. COOLER AIR WILL SETTLE IN BEHIND THIS FRONT INTO THE FIRST OF THE WEEK. COLD FRONT HAS ENTERED FAR NORTHWEST COUNTIES AND WILL CONTINUE SOUTHEAST THROUGH THE REST OF THE DAY. EXPECT HIGHS SUNDAY TO RANGE FROM THE LOWER 40S NORTH TO THE MID/UPR 50S FAR SOUTH.
THE NORTHERN EXTENT OF THIS PRECIP MAY NOT SURVIVE MUCH NORTH OF HIGHWAY 114 AS THE UPPER LOW /NOW WEST OF THE BIG BEND/ BEGINS MOVING MORE EAST THAN NORTH.
WITH THE SOUTHERN MIDSOUTH COUNTIES SEEING THE HIGHEST RAINFALL TOTALS.
THIS IS PRECEDING A DRIER AND SOMEWHAT COOLER AIR MASS WITH A 1030 MB HIGH PRESSURE CENTER LOCATED OVER THE CANADIAN PRAIRIE. A COLD FRONT PASSING THROUGH THE AREA THIS MORNING WILL SHIFT WINDS TO THE NORTHWEST AND BRING SOME MORNING CLOUDINESS TO PARTS OF THE CWA. SEVERAL DEGREES COOLER THEN YESTERDAY BUT STILL CLOSE TO NORMAL FOR THIS TIME OF YEAR. THE DRY CANADIAN AIR MASS WITH DEW POINTS IN THE TEENS OVER MN THIS MORNING WILL ALLOW FOR A COOLER NIGHT TONIGHT TEMPERED BY INCREASING CLOUDS. THE LATE WEEK PERIOD IS TRENDING COLDER FOLLOWING A COLD FRONT PROGGED TO PUSH THROUGH WED NIGHT. AND FREEZING RAIN ARE SUGGESTED EARLY. THIS WOULD THEN TRANSITION TO FREEZING RAIN OR DRIZZLE/ FREEZING DRIZZLE LATE NIGHT TOWARD SUNRISE AS THE LIFT AND SATURATION MOVES INTO A THERMAL PROFILE LESS FAVORABLE FOR ICE PRODUCTION.
250 PM CDT Sat Mar 21 2015 Cold front has cleared the CWA as of 2 pm, but the significantly cooler air lags behind in Wisconsin and northern Iowa. High pressure axis extends southeast from Minnesota into our area, and this will build east across the Great Lakes region tonight. This will result in winds turning more northeast and then east with time, allowing the cooler air mass to settle into the area for the rest of the weekend. Temperatures should dip to around freezing along the I-74 corridor, with mainly mid 30s elsewhere. Canadian high pressure will build across the area in the wake of today's cold front, keeping quiet weather in place but holding high temperatures in the 50s areawide.
Cirrus remains rather prevalent over southeastern Kansas associated with the cutoff system over Baja, while a weak cold front via a northern branch wave was sinking south through Nebraska early this morning.
WARMER AIR IS EXPECTED TO PUSH BACK INTO THE FAR SOUTHWEST CWA THIS AFTERNOON WITH HIGHS IN THE UPPER 50S TO POSSIBLY 65 DEGREES. AN AREA OF HIGH PRESSURE NORTHEAST OF THE REGION WILL FILTER COOLER AND DRIER AIR INTO THE CWA THROUGH AT LEAST MID MORNING. THIS HIGH WILL RETREAT NORTH THROUGH THE DAY IN RESPONSE TO A LOW PRESSURE SYSTEM WEST OF THE REGION. ALONG WITH A WEAK UPPER LEVEL TROUGH WILL TRACK ACROSS THE REGION LATE TONIGHT THROUGH SUNDAY EVENING. THERE IS A CONCERN WITH THE AMOUNT OF DRY AIR IN THE LOWER LEVELS WHICH WOULD LIMIT PCPN AMOUNTS.
153 PM CDT Sat Mar 21 2015 An upper low was located over Northern Mexico this morning lifting northeast across the area this afternoon. Behind this low will have weak ridging aloft resulting in mild wx through most of the week.
WARM FRONT REMAINS STALLED JUST NORTH OF COAST. SOME CLEARING OF THE MARATHON CLOUDINESS EXPECTED AS THIS UPPER LOW EXITS EASTWARD.
High pressure will bring a relatively quiet weather day on Sunday.
206 PM EDT SAT MAR 21 2015 WEAK HIGH PRESSURE OVER THE AREA THIS AFTERNOON.
At the surface, the Ohio Valley lies in between weather systems and under the influence of weak high pressure. A cold front is advancing toward the area, currently stretched across central Illinois into northwest Ohio with a strong Canadian high pressure system building into the Upper Midwest. Locally, readings this afternoon have climbed into the lower to middle 60s under mostly to partly sunny skies and light winds. Meanwhile, the aforementioned cold front is slated to drop through southern Indiana late this evening and then across Kentucky during the overnight. Cool, dry, northeast flow will result in slightly cooler highs compared to today, although readings should still top out right around normal /upper 50s to lower 60s/ with mostly to partly sunny skies.
ADDITIONAL CHANCES FOR POPS INTO THE EVENING AND OVERNIGHT HOURS WILL BE ASSOCIATED WITH THIS UPPER LEVEL LOW. DUE TO A SLIGHT CHANCE FOR WRAP AROUND PRECIP ON THE BACKSIDE OF THE UPPER LEVEL LOW.
439 PM EDT SAT MAR 21 2015 A COLD FRONT WILL WORK THROUGH THE AREA THIS EVENING. AFTER THE PASSAGE OF THIS FEATURE HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION AND REMAIN ACROSS THE AREA THROUGH SUNDAY NIGHT.
DRAGGING A COLD FRONT THROUGH THE REGION DURING THE DAY WITH WINDS BECOMING WLY IN ITS WAKE. SHOWERS AND A FEW THUNDERSTORMS NOW OVER SOUTH AND EAST TEXAS WILL ADVANCE INTO THE AREA AS THE AFOREMENTIONED TROF NEARS. CLOUDS AND RAINS WILL KEEP THE TEMPS COOLER THAN YESTERDAY. BY LATE ON SUNDAY THE FRONTAL BOUNDARY IS EXPECTED TO FINALLY GET A KICK AS THE UPPER LEVEL TROF WILL MOVE NORTHEAST OF THE REGION.
539 PM EDT SAT MAR 21 2015 A COLD FRONT WILL PUSH SOUTHEAST ACROSS THE REGION THIS AFTERNOON AND EVENING. THE LOW CLOUDS HAVE LIFTED AND MIXED OUT SOMEWHAT. BUT FORECAST SOUNDINGS AND RH PROFILES INDICATE THAT THE HIGH PRESSURE AREA SHOULD BE MORE SUCCESSFUL IN BRINGING DRIER AND BRIGHTER CONDITIONS WITH A DECENT BREEZE OUT OF THE NW AT 10-20 MPH.
HIGH TEMPERATURES WILL CONTINUE TO CLIMB INTO THE 70S ACROSS MOST LOCATIONS ACROSS THE HIGH PLAINS INTO WESTERN NEBRASKA. A FEW LOCATIONS IN THE LOWEST VALLEYS. THE UPPER LEVEL DIVERGENCE ASSOCIATED WITH THE JET STREAK MAY RESULT IN ENOUGH LIFT FOR SCATTERED SHOWERS DEVELOPING INTO THE HIGH PLAINS. HIGH TEMPERATURES WILL BE A FEW DEGREES COOLER ON SUNDAY BUT WILL STILL BE ABOVE NORMAL FOR THIS TIME OF THE YEAR.
WEAK LOW PRESSURE RIDE EAST ALONG THE STATIONARY FRONT APPROACHING SE GA OVERNIGHT. ANOTHER MILD AND MUGGY NIGHT IS EXPECTED WITH LOWS IN THE LOWER TO MID 60S. WAVES OF LOW PRESSURE WILL CONTINUE TO MOVE ALONG THE FRONTAL BOUNDARY CLOSE TO THE GA/FL BORDER. TO THE LOWER/MID 80S FOR INLAND SECTIONS OF NE FL.
DRY AIR IN THE LOW LEVELS VIA LIGHT NORTHERLY TO NORTHEASTERLY FLOW HAS KEPT PRECIPITATION FROM REACHING THE GROUND WITH DEWPOINT DEPRESSIONS BETWEEN 10 AND 20 DEGREES IN NORTHERN ALABAMA SO FAR. THIS EVENING WINDS WILL BECOME MORE SOUTHERLY AND ADVECT MORE MOISTURE INTO THE LOWEST LEVELS OF THE ATMOSPHERE (BELOW 850 MB).
1109 AM MDT SAT MAR 21 2015 UPPER LOW OVER OLD MEXICO WILL MOVE INTO SRN TX BY THIS EVENING ALLOWING FLAT UPPER LEVEL RIDGE TO TRANSLATE EASTWARD OVER CO. WITH TEMPERATURES REBOUNDING BACK INTO THE 70S ACROSS THE LOWER ELEVATIONS. SHOULD BE A MILD NIGHT AS WELL AS WESTERLY FLOW ALOFT STRENGTHENS SLIGHTLY AND LEE TROF SHIFTS EASTWARD INTO THE PLAINS. THIS WILL KEEP ENHANCED WESTERLY DRAINAGE WINDS ALONG THE LOWER EASTERN SLOPES OF THE SOUTHEAST MOUNTAINS/I-25 CORRIDOR.
SOME DRY AIR REMAINS IN THE LOWER LEVELS DUE TO THE NORTHERLY FLOW. LIGHT RAIN WILL ALSO HELP THIS MOISTENING PROCESS BUT DID DELAY THE LOWER CEILINGS A FEW HOURS FROM PREVIOUS FORECAST. CURRENTLY WITH A BOUNDARY ALONG THE GULF COAST AND A WEAK RIDGE ACROSS A CHUNK OF THE SOUTHERN U. THE BOUNDARY ACROSS THE COAST SHOULD SHIFT NORTHWARD OVER LOUISIANA AND EASTWARD TO THE ALABAMA GULF COAST WITH A WARM FRONTAL BOUNDARY DEVELOPING BY SUNDAY. A LOW PRESSURE SYSTEM OVER THE GREAT LAKES WILL DRAG A FRONT ACROSS THE EASTERN U.
A PACIFIC TROUGH AND COLD FRONT WILL MOVE EAST ACROSS THE AREA TONIGHT AND SUNDAY. WHILE THE LOWER ELEVATIONS WILL SEE MAINLY INCREASING CLOUD COVER AND A WIND SHIFT TO THE NORTH. THE COLD FRONT BESIDES BRINGING A WIND SHIFT. WILL BRING COOLER TEMPERATURES ESPECIALLY TO THE NORTH. SOME LIGHT SNOW WILL FALL IN THE HIGHEST MOUNTAINS.
HIGH TEMPERATURES WILL BE 5-10F COOLER ON SUNDAY WITH HIGHS ONLY REACHING THE 60S. AFTERNOON NORTHWEST BREEZES WILL MAKE IT FEEL COOLER TOO AS GUSTS REACH 20-25 MPH ON THE ERN PLAINS.
128 PM CDT SAT MAR 21 2015 COLD FRONT LOOKS TO HAVE GONE STATIONARY AT LEAST FOR A LITTLE WHILE.
DEGREE OF LOW LEVEL COLD AIR ADVECTION WITH THE SURFACE ANTICYCLONE PUSHING INTO THE CENTRAL GREAT LAKES.
LOOK FOR THE WIDESPREAD PRECIP TO CONTINUE THIS EVENING AND OVERNIGHT AS INCREASING WAA TAKES SHAPE IN RESPONSE TO THE APPROACHING UPPER LOW OFF TO OUR WEST. THIS WILL OCCUR AS MORE OF A SFC WAVE DEVELOPS WITH MORE OF A WARM FRONTAL LOOK TO THINGS AS WE APPROACH 12Z SUN. LOOK FOR THE HIGHEST COVERAGE (MORE WIDESPREAD NATURE) OF THE PRECIP SUNDAY TO BE DURING THE MORNING. STRONG MID LEVEL COOLING WILL OCCUR WHILE THE LOWER LEVELS WARM. THIS WILL RESULT IN STEEPENING LAPSE RATES WHICH WILL SUPPORT THE HIGHER INSTABILITY. LOOK FOR CAA CLOUDS TO LINGER WITH SOME LIGHT RAIN/DRIZZLE AS THE UPPER TROUGH AXIS MOVES OVERHEAD.
THE UPPER LOW THAT HAS BEEN OVER MEXICO FOR MANY DAYS NOW IS FINALLY MOVING EAST ACROSS WEST TEXAS. THIS LOW WILL CONTINUE TO GRADUALLY OPEN UP AS IT MOVES ACROSS TEXAS AND WILL INDUCE SURFACE CYCLOGENESIS NEAR THE TEXAS COAST THIS EVENING. THE LOW WILL LIKELY FORM AN A STALLED FRONTAL BOUNDARY THAT EXTENDS EASTWARD ALONG THE GULF COAST ALL THE WAY TO NORTH FLORIDA AND BEYOND.
COOLER TEMPERATURES AND SLIGHT CHANCES FOR SHOWERS IN THE WHITE MOUNTAINS REGION ARE IN THE FORECAST MIDWEEK.
346 PM CDT SAT MAR 21 2015 HIGH PRESSURE RIDGE FROM MANITOBA INTO MO WILL MOVE EAST TONIGHT WITH WINDS TURNING AROUND TO THE SOUTHEAST BY MORNING. LOW PRESSURE DEVELOPING OVER THE NORTHERN ROCKIES WILL BEGIN TO AFFECT THE AREA. TEMPERATURES WILL FALL OFF RAPIDLY TONIGHT WITH THE VERY DRY AIR IN PLACE WITH SUB FREEZING TEMPERATURES OVER ABOUT THE NORTHEAST HALF OF THE CWA.
THINK WE SHOULD REMAIN DRY THROUGH MUCH OF THE NIGHT THANKS TO CONTINUED DRY AIR ADVECTION AND THE MAIN UPPER TROUGH NOT APPROACHING UNTIL TOMORROW.
326 PM CDT SAT MAR 21 2015 AN UPPER LEVEL LOW PRESSURE CENTER CAN BE SEEN MOVING EAST FROM NORTHEAST MEXICO INTO THE BIG BEND REGION OF WEST TEXAS. THE MAJORITY OF THE RAIN HAS OCCURRED ACROSS THE SOUTHERN COUNTIES OF NORTH TEXAS WHERE THE HIGHEST MOISTURE LEVELS ARE IN PLACE. ADDITIONAL RAINFALL WILL OCCUR AREA-WIDE THIS EVENING AND OVERNIGHT AS THE UPPER TROUGH MOVES OVERHEAD. RAIN CHANCES WILL END TOMORROW AS THE UPPER LEVEL SYSTEM HEADS FOR THE LOWER MS VALLEY.
126 PM PDT SAT MAR 21 2015 HIGH PRESSURE ALOFT TODAY WILL MOVE EAST AS A WEAK LOW PRESSURE TROUGH APPROACHES FROM THE WEST.
132 PM EDT SAT MAR 21 2015 AVIATION AFTER SOME EARLY MORNING LIGHT RAIN SHOWERS TODAY FAIR WEATHER WILL RETURN AND IT WILL TURN COOLER.
/ISSUED 323 AM CDT SAT MAR 21 2015/ UPPER LOW THAT HAS BEEN LOCATED NEAR THE BAJA THE LAST COUPLE OF DAYS WILL MOVE NORTHEAST TOWARD THE AREA TODAY.
DEEP LAYERED RIDGING CENTERED OVER WESTERN CUBA IS PREVENTING ANYTHING RESEMBLING SHOWERS.
341 PM CDT SAT MAR 21 2015 THE SHORT TERM WILL FEATURE TWO SHORT WAVE TROUGHS OFF THE PACIFIC AFFECTING OUR CWA.
242 PM CDT SAT MAR 21 2015 WIDESPREAD CIRRUS HAVE SPREAD DOWNSTREAM ACROSS THE CENTRAL PLAINS FROM A SOUTHERN PLAINS MID/UPPER TROUGH.
UPPER RIDGING OVER THE SOUTHERN GULF AND WESTERN CARIBBEAN WILL WEAKEN TONIGHT INTO SUNDAY AS A SHORT WAVE TROUGH MOVES EAST FROM NORTHERN MEXICO INTO THE LOWER MISSISSIPPI VALLEY. AS THE SHORT WAVE MOVES EAST WEAK LOW PRESSURE WILL DEVELOP ALONG A STALLED FRONTAL BOUNDARY LOCATED ACROSS THE NORTHERN GULF COAST ON SUNDAY.
246 PM EDT SAT MAR 21 2015 AFTER A COLD FRONT PASSES THIS EVENING. HIGH PRESSURE WILL BRING DRY AND COOL CONDITIONS SUNDAY AND TO START THE WORK WEEK. COLD FRONT EXTENDED FROM NEAR KFKL TO KCMH AT 18Z AND WILL SWEEP ACROSS THE REGION THIS EVENING. ONLY LOW CHANCE POPS FOR A SHOWER WITH FROPA INTO THE RIDGES THIS EVENING. OTHERWISE COLD HIGH PRESSURE WILL BUILD IN THROUGH THE DAY SUNDAY.
A RIDGE OF HIGH PRESSURE WILL CONTINUE TO DOMINATE THE WEATHER ACROSS SOUTH FLORIDA. A STATIONARY FRONT CONTINUES TO LINGER ALONG THE NORTH FLORIDA BORDER WITH WEAK HIGH PRESSURE AND A WEAK PRESSURE GRADIENT ACROSS SOUTH FLORIDA AND ADJACENT WATERS. AN UPPER LEVEL RIDGE CONTINUES TO DOMINATE ACROSS THE CENTRAL AND EASTERN GULF AND EXTENDS ACROSS THE FLORIDA PENINSULA. THE MID TO UPPER LEVEL RIDGE ACROSS THE REGION WILL SLOWLY START TO ERODE AND BECOME MORE ZONAL FLOW AS AN UPPER LEVEL TROUGH IS FORECAST TO ENTER THE WESTERN GULF LATER ON SUNDAY. BUT WEAK HIGH PRESSURE AND LACK OF AVAILABLE DEEP MOISTURE WILL CONTINUE ACROSS THE REGION.
THIS WILL RESULT IN NORTHEASTERLY WINDS EARLY IN THE DAY BUT BECOMING SOUTHEAST THIS AFTERNOON AS THE FRONT LIFTS BACK NORTH IN RESPONSE TO DEVELOPING LOW PRESSURE ACROSS THE HIGH PLAINS. SHOULD BE ANOTHER STELLAR DAY WITH HIGHS IN THE LOWER 60S NORTH AND AROUND 70 SOUTH. SUNDAY TEMPS DO WARM INTO THE LOWER TO MID 70S AHEAD OF A CLIPPER/COLD FRONT THAT DOES MOVE INTO THE AREA BY PEAK HEATING. ALONG WITH BROKEN CLOUDS RESULTS IN COOLER HIGHS IN THE UPPER 50S TO LOWER 60S.
335 PM EDT SAT MAR 21 2015 A DRY COLD FRONT WILL CROSS THE AREA FROM THE WEST TONIGHT FOLLOWED BY COOLER HIGH PRESSURE FOR SUNDAY.
Heavy rain and potential flooding still on track today for The upper level low spinning to our west is finally beginning to lift northeast.
225 PM CDT SAT MAR 21 2015 HIGH PRESSURE OVER THE TN VALLEY WILL GIVE WAY AS A COLD FRONT MAKES PASSAGE ACROSS THE OHIO VALLEY LATER THIS AFTERNOON/EVENING. ALSO AT PLAY WILL BE A DEVELOPING LONG WAVE TROF MOVING INTO THE MS VALLEY LATER TONIGHT- TMRW. THE NET EFFECT WILL BE A SLIGHTLY COOLER BUT STILL NICE DAY TMRW WITH JUST A LITTLE MORE IN THE WAY OF CLOUDS AND TEMPS RUNNING THRU MAINLY THE LOW TO MID 60S FOR HIGHS. THIS TROF MOVES EAST ACROSS THE DEEP SOUTH AND KEEPS ITS PRECIPITATING MOISTURE TO OUR SOUTH.
AN UPPER RIDGE WILL BUILD INTO THE REGION FOR SUNDAY BRINGING DRYING CONDITIONS. COMPLETE WITH A TROUGH OF WARM AIR ALOFT.
OTHERWISE LIGHT NORTHEASTERLY TO NORTH WINDS AS AN AREA OF HIGH PRESSURE MOVES FROM SOUTHERN MANITOBA INTO NORTHERN MINNESOTA. IN AREAS OF CLOUD COVER LOWS WILL BE IN THE LOW 20S. HIGHS IN THE LOW TO MID 30S.
303 PM CDT SAT MAR 21 2015 MATURE UPPER CYCLONE CENTERED NEAR THE DAVIS MTNS WILL CONTINUE TRACKING NORTHEAST BEFORE ITS DEFORMATION ZONE EXITS OUR SOUTHERN COUNTIES BEFORE DAYBREAK ON SUNDAY. THE SATELLITE PRESENTATION OF THIS LOW AND STIPPLING OF CLOUDS IN THE DEFORMATION ZONE INDICATE NO SHORTAGE OF LIFT. HEIGHT FIELDS AND THICKNESSES REBOUND NICELY TOMORROW DOWNSTREAM OF AN UPPER RIDGE.
535 PM EDT SAT MAR 21 2015 AFTER A COLD FRONT PASSES THIS EVENING. HIGH PRESSURE WILL BRING DRY AND COOL CONDITIONS SUNDAY AND TO START THE WORK WEEK. COLD FRONT HAS MADE IT TO KPIT AS OF THIS HOUR. HAVE UPDATED THE DIURNAL TREND AND LOW TEMPERATURES TONIGHT PER THE LATEST HI RES MODEL DATA WITH THE EXPECTATION THAT SKIES WILL SCATTER OUT AND WINDS WILL DECREASE WITH BUILDING HIGH PRESSURE. OTHERWISE COLD HIGH PRESSURE WILL BUILD IN THROUGH THE DAY SUNDAY.
WITH THE WARMER FLOW AHEAD OF THE NEXT SYSTEM. WILL LEAN TOWARDS THE WARMER GUIDANCE FOR TODAY. THE NEXT UPPER TROUGH WILL BE DEVELOPING OVER THE UPPER MIDWEST TODAY AND DROP SOUTHEAST TONIGHT. A COLD FRONT AT THE SURFACE WILL MOVE TOWARDS THE AREA AND SHOULD BE THROUGH BY MIDNIGHT/06Z. WITH THE UPPER TROUGH SWINGING THROUGH.
The 11 pm EST regional surface analysis showed an east-west oriented ridge across the Southeast. Surface pressures were falling across the western Gulf of Mexico, as a mid-upper level trough approached from the west.
HIGH PRESSURE ALOFT WILL RETURN TO THE AREA THURSDAY AND REMAIN OVER THE REGION THROUGH THE WEEKEND.
547 AM CST Wed Feb 4 2015 A surface cold front is beginning to move into central IL from the northwest this morning and has reached Peoria as of 3 a. Beyond tonight, high pressure builds into the region through the end of the week.
THE COLD FRONT PUSHES ACROSS THE REMAINDER OF THE SOUTHWEST PORTION OF THE FORECAST AREA EARLY THIS MORNING WITH LOW CLOUDS AND AREAS OF FOG IMMEDIATELY BEHIND THE FRONT. THE BEST CHANCE OF ACCUMULATING SNOW WILL BE ACROSS FAR NORTHEAST COLORADO AND THE NEBRASKA BORDER AREA DURING THE MORNING AS THE UPPER SHORT WAVE TROUGH SWEEPS THROUGH THE NORTHWEST FLOW ALOFT. THE SHORT WAVE TROUGH AXIS MOVES EAST OF THE CENTRAL HIGH PLAINS REGION WITH SUBSIDENCE AND SOME DRYING ALOFT WITH SNOW DIMINISHING THROUGH THE AFTERNOON AND COMING TO AN END BEFORE 00Z. THE COLD AIRMASS PUSHES EAST QUICKLY BY THURSDAY AS A LEE TROUGH BEGINS TO DEVELOP ALONG THE ROCKIES AND WEST TO SOUTHWEST WINDS TAKE OVER AT THE SURFACE. THE UPPER RIDGE OVER THE WESTERN UNITED STATES ALSO MOVES OVER THE ROCKIES AND HIGH PLAINS.
