1151 PM CDT Sat May 30 2015 A surface cold front has pushed through the forecast area, with cooler and drier air advecting into the region. While a few pockets of drizzle will be possible through tonight as the upper trough axis passes through, the large majority of the area will remain dry, with all measurable precipitation to the east of the forecast area. Temperatures on Sunday will be several degrees warmer than today, with highs in the middle 60s to lower 70s. Overnight lows Sunday night will once again be cool with the dry airmass, clear skies, and light easterly winds, with readings in the lower 50s.
903 PM EDT SAT MAY 30 2015 WARM AND HUMID CONDITIONS WILL CONTINUE UNTIL THE PASSAGE OF A STRONG COLD FRONT LATE SUNDAY. COOLER WEATHER WILL SETTLE OVER THE REGION TO START THE WORK WEEK. THE ONLY EXCEPTION WOULD BE IN THE HIGHER TERRAIN WITH OROGRAPHIC ENHANCEMENT. MODELS HAVE SLOWED THE COLD FRONTAL PASSAGE LATE SUNDAY.
A COLD FRONT HAS PUSHED ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS AND EXITED TO THE EAST SOUTHEAST OF THE CWA.
AN ATLANTIC RIDGE OF HIGH PRESSURE WILL EXTEND ACROSS THE CAROLINAS TONIGHT THROUGH SUNDAY NIGHT.
750 PM EDT SAT MAY 30 2015 A STRONG COLD FRONT WILL MOVE SOUTHEAST ACROSS THE AREA THIS EVENING. HEAVY AT TIMES ESPECIALLY THIS EVENING WILL CONTINUE INTO SUNDAY MORNING BEFORE ENDING AS A LOW PRESSURE SYSTEM MOVES NORTHEAST ALONG THE FRONT. WITH LAKE ENHANCED COLD FRONT NOW WELL INLAND EXPECT THE HEAVY RAIN THREAT TO BE NEAR THIS BAROCLINIC ZONE SO OPTED TO KEEP LAPORTE AND BERRIEN OUT OF WATCH AT THIS TIME.
WE RECENTLY UPDATED FORECASTS FOR HARNEY AND MALHEUR COUNTIES AND THE LOWER TREASURE VALLEY FOR SHOWERS AND THUNDERSTORMS THIS EVENING. CLOUD COVER HELD TEMPS DOWN TODAY IN PARTS OF OUR CWA BUT FEWER CLOUDS ARE EXPECTED SUNDAY AND TEMPS WILL REACH SUMMERTIME LEVELS AS UPPER RIDGE AMPLIFIES DIRECTLY OVER US.
COLD FRONT WILL MOVE SLOWLY ACROSS MIDDLE TENNESSEE LATE TONIGHT AND TOMORROW, WITH SCATTERED THUNDERSTORMS DEVELOPING MAINLY DURING THE AFTERNOON THROUGH EARLY EVENING. HOWEVER, BELIEVE AIR MASS EAST OF COLD FRONT NEAR THE MISSISSIPPI RIVER WILL BE SUFFICIENTLY MOIST AND UNSTABLE TO WARRANT AT LEAST A CHANCE POP FOR TONIGHT.
THE MAIN HIGH PRESSURE WILL BE TO THE NORTH. BUT THE HIGH WILL HELP TO KEEP SKIES CLEAR ACROSS THE AREA TONIGHT. AS THIS MOISTURE BUILDS AND WARMER AIR ADVECTS NORTHWARD.
324 PM CST TUE MAR 8 2016 MAIN FORECAST CONCERNS FOR THIS EVENING IS WHETHER OR NOT WE WILL SEE SHOWER/THUNDERSTORM DEVELOPMENT ALONG A COLD FRONT MARCHING EASTWARD ACROSS THE FORECAST AREA. WE SHOULD THEN SEE A BREAK IN PRECIPITATION CHANCES FOR WEDNESDAY AFTERNOON BUT IT WILL BE COOLER IN THE WAKE OF THE FRONT WITH HIGHS ON WEDNESDAY ONLY MAKING IT INTO THE UPPER 40S TO MID 50S.
THE QUESTION IS JUST HOW LONG IT WILL HOLD OUT BEFORE THE LOWER LAYERS HAVE SATURATEDENOUGH FOR IT TO REACH THE GROUND. /ISSUED 359 AM CST TUE MAR 8 2016/ COLD FRONT MOVING SOUTH AND EAST ACROSS THE PANHANDLES THIS MORNING WILL BECOMING QUASI-STATIONARY BY THIS AFTERNOON AND THIS EVENING BEFORE CONTINUING TO PUSH SOUTH AGAIN TONIGHT.
212 PM EST TUE MAR 8 2016 WARM AND DRY UNDER HIGH PRESSURE THROUGH WEDNESDAY. LOW PRESSURE WITH RAIN BY LATE WEEK. HIGH PRESSURE STAVES OFF WEATHER TO THE WEST.
THE UPPER LOW PRESSURE SYSTEM WAS OVER OLD MEXICO. MODELS HAVE BEEN SLOW TO REACT TO THE MORE SOUTHERN ROUTE OF THE UPPER LOW. MODELS INDICATE THAT THE UPPER LOW WILL CONTINUE WELL TO THE SOUTH OF THE STATE TONIGHT. TEENS TO SINGLE DIGITS FOR THE HIGHER ELEVATIONS. AS WELL AS AFTN MAX TEMPS ABOUT 3-5 DEGREES WARMER THAN THOSE EXPERIENCED TODAY.
240 PM EST TUE MAR 8 2016 FAIRLY QUIET WEATHER EXPECTED THE NEXT FEW DAYS AS A STRONG RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE EASTERN GULF AND WESTERN ATLANTIC. SOME LIMITED MOISTURE WILL BE IN PLACE IN THE LOW LEVELS COURTESY OF THIS FLOW REGIME WHICH COULD ALLOW FOR SOME LOW CLOUDS ACROSS THE AREA. OVERNIGHT TEMPERATURES WILL AGAIN BE A FEW DEGREES WARMER THAN LAST NIGHT. ALTHOUGH WARMER. MOST OF THE AREA CAN EXPECT TEMPERATURES IN THE LOW TO MID 80S EXCEPT MAYBE RIGHT ALONG THE IMMEDIATE COAST.
EXPECT THE LOW LEVEL MOISTURE TRANSPORT TO CONTINUE OVER MOST OF SOUTHERN KS FOR THE DAYTIME HOURS AS ANOTHER WEAK IMPULSE MOVES NORTHEAST OUT OF THE SRN PLAINS AND THEN ACROSS THE ERN HALF OF KS. BOTH THE GFS AND ECMWF ARE SIMILAR IN PUSHING THE STATIONARY FRONT BACK TO THE SOUTHEAST ON THU AS A COLD FRONT. THE UNCERTAINTY COMES ON HOW THE MEDIUM RANGE MODELS HANDLE THE SOUTHERN STREAM CLOSED LOW EXPECTED TO BE LOCATED OVER SRN TX. THE GFS HAS BEEN CONSISTENT IN LIFTING THIS LOW STRAIGHT NORTH OVER ERN KS FOR LATE THU THRU FRI. NOW SHEARING THIS UPPER LOW STRAIGHT EAST INTO THE GULF COAST STATES.
MOISTURE WILL ARRIVE VIA A WARM FRONT THIS AFTERNOON. A WARM FRONT WILL SPREAD ADDITIONAL PRECIPITATION AND LOW CEILINGS INTO THE AREA BY EARLY WEDNESDAY MORNING. SEAS WILL BECOME INCREASINGLY CHOPPY TODAY AS SOUTHERLY WINDS INCREASE ALONG A WARM FRONT.
339 PM CST TUE MAR 8 2016 THE TWIN CITIES HAD THEIR FIRST OFFICIAL 70 DEGREE DAY THIS AFTN AS STRONG MIXING AHEAD OF A COLD FRONT DEVELOPED. THE MAIN COLD FRONT THIS AFTN WAS ASSOCIATED WITH AN AREA OF LOW CLOUDS AND TEMPERATURES FALLING BACK INTO THE 50S ACROSS WC/SW/SC MN. AS THE MAIN UPPER LOW MOVES EAST-NORTHEAST ACROSS THE GREAT LAKES. AS A DEEP UPPER LOW BECOMES NEARLY STATIONARY ACROSS SOUTHERN TEXAS THROUGH THIS WEEKEND. MOST OF SOUTHERN MINNESOTA WILL LIKELY NOT SEE ANY BELOW FREEZING TEMPERATURES FOR THE NEXT 7 DAYS.
241 PM CST TUE MAR 8 2016 AT H5 CLOSED LOW OVER NORTHERN MEXICO. SLOW TO ERODE STRATUS ACROSS NORTHERN NEBRASKA HAS RESULTED IN MUCH COOLER THAN ANTICIPATED MAX TEMPS TODAY. DENSE CIRRUS FROM THE STRONG LOW PRESSURE OVER THE SOUTHERN PLAINS WILL CONTINUE EXPANDING NORTH INTO CENTRAL NEBRASKA. THE SFC/850HPA TROUGH MOVE INTO THE PANHANDLE AND WESTERN SANDHILLS AND MAIN 500HPA WAVE ARRIVING LATER. WITH DEEP DRY LAYER IN THE LOW LEVELS. WEAK TROUGH MOVES ACROSS NORTHERN PLAINS. PHASING WITH UPPER CLOSED LOW OVER RIO GRANDE VALLEY. SOME INSTABILITY AND CAPE WITH 7K FT CEILINGS AND LIFT FROM 00Z THROUGH 06Z AS UPPER TROUGH MOVES THROUGH AND WEAK LLJ INCREASES.
234 PM EST TUE MAR 8 2016 HIGH PRESSURE WILL REMAIN ANCHORED OFF THE SOUTHEAST COAST AS IT SHIFTS SLOWLY EAST THROUGH THE WEEK.
346 PM EST TUE MAR 8 2016 HIGH PRESSURE OVER THE CAROLINAS WILL CONTINUE TO PUMP A SOUTH FLOW OF UNSEASONABLY WARM AIR THROUGH MID WEEK.
EVEN AS TEMPERATURES AT THE SFC ARE STILL ABOVE THE FREEZING MARK IT SEEMS THAT THERE IS A WARM AND COLD LAYER JUST ABOVE. KEPT A THUNDER MENTION GOING AS THERE STILL IS A TONGUE OF INSTABILITY WRAPPING AROUND THE BACK OF THE LOW AND WE ARE STILL GETTING LIGHTNING REPORTS. SEVERAL OF THE HIGH RES SHORT RANGE MODELS HAVE THIS WAVE PRODUCING SOME PRECIP RIGHT ALONG OUR FAR SOUTHERN BORDER AFTER 09Z OR SO AND CONTINUING INTO TOMORROW MORNING. AN UPPER TROUGH WILL BE MOVING THROUGH THE NORTHERN PLAINS BUT THERE IS GOOD AGREEMENT ON NOT MUCH COMING FROM IT. TEMPS WILL REMAIN COOLER THAN THEY HAVE BEEN BUT NOT AS COLD AS SEASONAL AVERAGES.
UPPER RIDGE IS HOLDING STRONG AND WILL RESULT IN AN UNSEASONABLY WARM AND WINDY AFTERNOON.
MODELS SHOW A WEAK UPPER LEVEL TROUGH AXIS QUICKLY MOVING ACROSS THE AREA ON WEDNESDAY. OTHER THAN SOME MODERATE RAIN/SNOW SHOWER ACTIVITY AND SOME COOLER AIR. THERE IS SOME DECENT LLVL INSTABILITY PRESENT DURING THE AFTERNOON AS THE TROUGH AXIS MOVES ACROSS THE AREA. WHICH MAY RESULT IN BRIEF MODERATE SNOW SHOWERS MOVING ACROSS THE HIGH VALLEYS AND INTO THE HIGH PLAINS. TEMPERATURES WILL BE A FEW DEGREES WARMER COMPARED TO TODAY AND GENERALLY RANGE FROM THE MID 40S WEST OF THE LARAMIE RANGE TO THE UPPER 50S ACROSS THE LOWER ELEVATIONS OF WESTERN NEBRASKA.
Low temperatures Wednesday morning again well above freezing and well above normal, ranging from mid 30s NW to the mid 40s SE. Strong upper low, currently unusually far south in Sonora, Mexico, will dig even further south into central Mexico on Wednesday. Dry and milder Wednesday, with variable amounts of high clouds allowing afternoon temperatures to recover to the lower 60s. Moisture and lift will continue along and just north of this boundary as an upper low moves very slowly east across northern Mexico and southern Texas. An upper level trough will cross the west central high plains late week as the upper low, located in south Texas mid week, begins to lift north northeast.
AS ANOTHER SMALL DISTURBANCE IN THE UPPER LEVELS OF THE ATMOSPHERE MOVES NE FROM THE MAIN UPPER LOW OVER MEXICO. AS AN UPPER LOW MOVES SLOWLY ACROSS NORTHERN MEXICO.
HAVE UPDATED THE HIGH TEMPS ACROSS THE MID STATE ON AVERAGE BY A COUPLE OF DEGREES FOR THIS AFTERNOON FOR THE SUITE OF FORECAST PRODUCTS.
314 PM CST TUE MAR 8 2016 THE 21Z SURFACE MAP AND IR/VISIBLE SATELLITE IMAGERY INDICATED THAT THE STRONG SURFACE TO UPPER LEVEL RIDGE AXIS WAS REMAINING IN CONTROL OF THE WEATHER FROM EAST OF THE MISSISSIPPI RIVER WITH JUST MID AND HIGH CLOUDS SPILLING INTO THE TENNESSEE VALLEY REGION. TEMPS THIS AFTERNOON UNDER PARTLY TO MOSTLY SUNNY SKIES RANGED FROM THE LOWER TO MID 70S. THE MODELS ARE IN FAIR AGREEMENT INVOLVING THE RIDGE AXIS ONLY SLOWLY SHIFTING EASTWARD AWAY FROM THE FORECAST AREA FURTHER OFF OF THE MID ATLANTIC COAST.
213 PM MST TUE MAR 8 2016 ISOLATED SHOWERS OR SPRINKLES ACROSS THE HIGHER TERRAIN EAST OF PHOENIX TODAY WILL DISSIPATE EARLY THIS EVENING.
307 PM CST TUE MAR 8 2016 Late this afternoon, a swath of showers and thunderstorms originating over Oklahoma will continue to lift north and east within an embedded upper trough across the CWA. Another limiting factor for any precip across a decent portion of north central Kansas is the cold front/dryline centered between Nemaha, through Alma and Council Grove. West of this line, drier air in the lower levels continues to undercut the precip shield, eroding the western flank of the storm cluster. Latest guidance continues to trend the upper low and optimal moisture further east, with the northern stream wave carrying cooler and drier air behind the sfc boundary into northeast Kansas. Cloud cover remains likely however with cooler temps in the lower 60s expected.
1040 AM MST TUE MAR 8 2016 CONVECTIVE SHOWERS STILL EXPECTED OVER THE HIGHER TERRAIN THIS AFTERNOON AND EVENING. A STG UPPER LEVEL LOW WILL REMAIN OVER MEXICO WHILE THE FLOW ALOFT ACROSS COLORADO IS WEAK SSW. IT APPEARS SOME MOISTURE FM THE UPPER LEVEL LOW WELL TO THE SOUTH WILL ADVECT INTO THE AREA BY THIS AFTN ESPECIALLY OVER THE HIGHER TERRAIN. MODELS HAVE A WEAK UPPER TROUGH MOVING ACROSS COLORADO ON WEDNESDAY.
WHILE THE CAN/T RULE OUT A FEW TORNADOES GIVEN FAVORABLE WINDS IN THE LOWEST FEW KM OF THE ATMOSPHERE.
335 PM CST TUE MAR 8 2016 A DEEP UPPER LEVEL LOW PRESSURE SYSTEM CONTINUES TO SPIN ACROSS NORTHWEST MEXICO AND WILL CONTINUE TO DIG INTO NORTH CENTRAL MEXICO OVER THE NEXT FEW DAYS BEFORE LIFTING NORTHEAST TOWARDS THE MID SOUTH OVER THE WEEKEND. THIS ACTIVITY SHOULD ALSO WEAKEN WITH EASTWARD EXTENT AS INSTABILITY WANES AND THE STORMS MOVE INTO AN AREA OF WARMER TEMPERATURES ALOFT. TROPICAL MOISTURE SHOULD BE THRUST NORTHWARD FROM CENTRAL AMERICA TO THE EAST OF THE UPPER LOW INTO OUR REGION.
218 PM CST TUE MAR 8 2016 Strong upper level low pressure area centered in northwest Mexico will slowly shift southeast into central Mexico through Wednesday night.
THE TYPE WOULD LIKELY BE RAIN OR FREEZING RAIN DUE TO WARM TEMPERATURES ALOFT.
314 PM EST TUE MAR 8 2016 HIGH PRESSURE WILL EXTEND ACROSS THE REGION THROUGH THE WEEK. CHARACTERIZED BY AN INTENSIFYING DEEP LAYERED RIDGE ACROSS THE EASTERN U. WITH A POWERFUL UPPER LOW QUICKLY CUTTING OFF FROM THE MAIN BELT OF THE WESTERLIES JUST SOUTH OF THE FOUR CORNERS REGION. QUIET WEATHER WILL CONTINUE TONIGHT AS THE AREA REMAINS ALONG THE WESTERN FLANKS OF ATLANTIC HIGH PRESSURE. LOWS WILL RANGE FROM AROUND 50 WELL INLAND TO THE LOWER-MID 50S AT THE COAST.
A WARM FRONT WAS LOCATED NEAR THE MINNESOTA AND IOWA BORDER. DEW POINTS THIS HIGH ARE RARE IN EARLY MARCH. 00Z MODELS ARE IN GOOD AGREEMENT THAT A SHORT WAVE TROUGH. A COLD FRONT WILL MOVE EAST ACROSS THE FORECAST AREA.
1106 AM EST TUE MAR 8 2016 HIGH PRESSURE WILL BRING DRY AND WARM WEATHER THROUGH MID WEEK.
A WEAK WARM FRONT WILL BE MOVING ACROSS THE REGION TODAY INTO TONIGHT. THIS SYSTEM WILL BE A STRONGER WARM FRONT WHICH WILL MOVE THROUGH WEDNESDAY. THIS IS THE RESULT OF A WEAKENING COLD FRONT AS IT MOVES INTO AND THROUGH THE REGION EXITING OVERNIGHT. THIS WILL BE FOLLOWED BY A WARM FRONTAL SYSTEM WEDNESDAY. THE WARM FRONT WILL ARRIVE INTO CENTRAL OREGON WEDNESDAY MORNING AND THEN SLOWLY LIFT NORTH INTO WASHINGTON WEDNESDAY NIGHT. WILL SEE INCREASING SOUTHERLY WINDS ASSOCIATED WITH THE WARM FRONT LATE WEDNESDAY AND WEDNESDAY NIGHT.
1246 PM EST TUE MAR 8 2016 DRY WEATHER WILL PERSIST TODAY IN THE CIRCULATION AROUND HIGH PRESSURE CENTERED TO THE SOUTHEAST.
Scattered shower activity will continue through early this evening, mainly across the higher terrain, then dissipate after sunset.
DRY CONDITIONS CONTINUE IN THE SOUTH-SOUTHEAST STEERING FLOW PATTERN AROUND HIGH PRESSURE CENTER. ABOVE NORMAL MAX TEMPS ARE EXPECTED IN THE 80-85 DEGREE RANGE INLAND AND COOLER 70S ALONG I-95/COASTAL COUNTIES/BEACHES.
IN ITS WAKE, A WEAK COLD FRONT HAS STALLED ACROSS NW AND W OK WITH A DRYLINE EXTENDING THROUGH PORTIONS OF WESTERN NORTH TEXAS AND WEST TX. THE UPPER LOW WILL FINALLY START ITS TRACK NORTH AND EASTWARD THUR, MOVING OVER SOUTH TEXAS AROUND FRI 00Z.
128 PM EST TUE MAR 8 2016 HIGH PRESSURE WILL BRING DRY AND WARM WEATHER THROUGH MID WEEK.
RAINFALL RATES OF 3 INCHES AN HOUR WILL BE LIKELY AND AS THE STORMS FORM THIS SWATH EXPECT WINDS TO LINE UP WITH COASTAL TROUGHING TO FOCUS RAINFALL FROM WHARTON TO HOUSTON TO LIVINGSTON.
The highest rainfall totals are still focused on the southeastern half of the area, with 4 to 7 inches possible. There continue to be minor fluctuations with where the heaviest band of rain sets up, but recent trends have definitely honed in on south central Missouri for the highest totals. This rainfall will occur over a period several days, beginning today and persisting in periodic fashion into this weekend as the main upper level low finally lifts through the area. As alluded to above, the main upper low will (finally) exit to the northeast late this weekend.
340 PM CST TUE MAR 8 2016 (Tonight and Wednesday) Currently, we have southwest flow aloft with a large/powerful upper level low moving southeast into central Mexico. This boundary could potentially serve as a focus for thunderstorms to develop on later this afternoon and evening with continued heating, and lift from the upper level low moving into the area. Farther west and south, scattered showers and thunderstorms are developing northwest of Del Rio, into the lower Trans Pecos and Stockton Plateau as lift from the upper level low begins to spread northeast into our region.
A WEAK TROUGH EMBEDDED IN THE FLOW ALOFT IS PROGGED TO MOVE ACROSS THE REGION. LAST OF SNOW SHOWERS IN THE NORTHERN MTNS THE PRODUCT OF WEAK INSTABILITY WITH COOLING ALOFT AND WEAK OROGRAPHICS INDUCED BY NWLY POST-TROUGH FLOW SHOULD QUICKLY WIND DOWN WEDNESDAY EVENING.
1020 AM CST TUE MAR 8 2016 NUMEROUS RAIN AND SNOW SHOWERS ALONG WITH SOME THUNDER WERE OCCURRING THIS MORNING AROUND A SPINNING UPPER LOW PRESSURE AREA. COOLER AIR AND CLOUD COVER SUPPORTS TEMPERATURES STRUGGLING TO MOVE VERY MUCH TODAY. WE WILL SEE THE SLOW PASSAGE OF A LONGWAVE TROF WEDNESDAY NIGHT.
300 PM CST TUE MAR 8 2016 MAIN WEATHER FEATURES IN THE SHORT TERM WILL REVOLVE AROUND SLOW MOVING CLOSED UPPER LOW OVER NORTHERN MEXICO AND COLD FRONT MOVING THROUGH THE REGION THIS AFTERNOON. THE SURFACE COLD FRONT STRETCHED FROM CENTRAL MINNESOTA ACROSS NORTHWEST IOWA AND EXTREME SOUTHEAST NEBRASKA INTO CENTRAL KANSAS AT 20Z. THE FRONT IS EXPECTED TO MOVE SLOWLY SOUTHEAST THIS EVENING WITH COOLER AND DRIER AIR SPREADING INTO EASTERN PARTS OF THE FORECAST AREA.
AN UPPER LEVEL TROUGH EXTENDING FROM SOUTHERN ALBERTA TO WESTERN IDAHO THIS MORNING WILL MOVE THROUGH CENTRAL AND SOUTHWEST MT TODAY.
1128 AM CST TUE MAR 8 2016 FOR 18Z TAFS /ISSUED 1001 AM CST TUE MAR 8 2016/ HIGH PRESSURE WILL CONTINUE TO SHIFT EASTWARD ACROSS MUCH OF THE REGION TODAY. WHILE THERE MAY BE A FEW GUSTS TO 30 MPH IN THE HIGHER ELEVATIONS.
257 PM EST TUE MAR 8 2016 HIGH PRESSURE WILL BRING DRY AND WARM WEATHER THROUGH MID WEEK.
320 PM CST TUE MAR 8 2016 STRONG UPPER LOW LIFTING NORTHEAST AND OUT OF THE REGION THROUGH THE REST OF THE AFTERNOON WILL BRING AN END TO THE WRAP AROUND SHOWERS. THE ISSUE TONIGHT WILL BE IF THE LOW CLOUDS BREAK UP AND HOW MUCH FOG WILL FORM. DONT EXPECT THE LOW CLOUDS TO BREAK UP ACROSS MAINLY THE EAST. WEDNESDAY WILL BE WARMER ACROSS THE CWA WITH HIGHS IN THE MID 40S TO THE MID 50S.
WEAK LONGWAVE TROUGH WILL TRAVELS THE REGION WED POSSIBLY SUPPORTING AN ISOLD SHRA OR TWO IN THE LATE AFTERNOON EVENING. MILD CONDS EXPECTED AHEAD OF A WEAK UPPER TROUGH AND ASSOCIATED LOW PRESSURE TROUGH.
159 PM EST TUE MAR 8 2016 HIGH PRESSURE ALONG THE CAROLINA COAST WILL STAY ANCHORED IN PLACE THROUGH THE END OF THE WEEK.
316 PM EST TUE MAR 8 2016 HIGH PRESSURE ALONG THE CAROLINA COAST WILL STAY ANCHORED IN PLACE THROUGH THE END OF THE WEEK.
BREEZY AT TIMES THIS AFTERNOON WILL CONTINUE INTO MIDWEEK AS HIGH PRESSURE ANCHORED OFF THE US SOUTHEAST COAST ACTS TO BOTH STABILIZE THE ATMOSPHERE WHILE PRODUCING A CONTINUATION OF SOUTHEAST FLOW. A RAIN FREE FORECAST DUE TO STRENGTH OF THE HIGH IN PROXIMITY TO THE AREA.
1157 AM CST TUE MAR 8 2016 NUMEROUS RAIN AND SNOW SHOWERS ALONG WITH SOME THUNDER WERE OCCURRING THIS MORNING AROUND A SPINNING UPPER LOW PRESSURE AREA. COOLER AIR AND CLOUD COVER SUPPORTS TEMPERATURES STRUGGLING TO MOVE VERY MUCH TODAY. WE WILL SEE THE SLOW PASSAGE OF A LONGWAVE TROF WEDNESDAY NIGHT.
328 PM EST TUE MAR 8 2016 AS LOW PRESSURE MOVES EAST THROUGH CANADA A WARM FRONT WILL MOVE NORTH THROUGH NEW ENGLAND TONIGHT BRINING VERY WARM CONDITIONS WEDNESDAY. AS THE LOW MOVES EAST INTO THE GULF OF SAINT LAWRENCE A COLD FRONT WILL DROP SOUTH INTO MAINE AND NEW HAMPSHIRE WEDNESDAY NIGHT BEFORE STALLING.
1226 PM EST TUE MAR 8 2016 ATLANTIC HIGH PRESSURE WILL EXTEND ACROSS THE AREA THIS WEEK WITH TEMPERATURES WELL ABOVE NORMAL. CHARACTERIZED BY AN INTENSIFYING DEEP LAYERED RIDGE ACROSS THE EASTERN U. WITH A POWERFUL UPPER LOW QUICKLY CUTTING OFF FROM THE MAIN BELT OF THE WESTERLIES JUST SOUTH OF THE FOUR CORNERS REGION. THE BUILDING UPPER RIDGE OVER THE AREA WILL PROMOTE ANOTHER DRY AND WARM DAY WITH TEMPERATURES RANGING FROM NEAR 80 ACROSS PARTS OF INTERIOR SOUTHEAST GEORGIA TO THE UPPER 50S/LOWER 60S ALONG THE BEACHES. ATLANTIC HIGH PRESSURE WILL MAINTAIN A LOW LEVEL ONSHORE FLOW. IT SHOULD BE A RATHER MILD NIGHT WITH LOWS IN THE LOWER 50S INLAND FROM THE WARMER COASTAL COMMUNITIES.
328 PM CST TUE MAR 8 2016 LOW PRESSURE WRAPPING UP AND LIFTING NORTHEAST LEAVING BEHIND WIDESPREAD STRATUS AND A BREEZY NORTHWEST WIND. AS THE LOW RAPIDLY EXITS NORTHWEST WINDS WILL QUICKLY DIMINISH OVERNIGHT. EXPECT THE FOG TO LIFT AND THE STRATUS TO EXIT WHICH WILL SET UP A VERY NICE WEDNESDAY WITH WINDS MAINLY LESS THAN 15 MPH AS A RIDGE OF HIGH PRESSURE MOVES THROUGH.
HIGH PRESSURE WILL CONTINUE TO SHIFT EASTWARD ACROSS MUCH OF THE REGION TODAY. WHILE THERE MAY BE A FEW GUSTS TO 30 MPH IN THE HIGHER ELEVATIONS.
LATEST SATELLITE IMAGERY SHOWED A CLOSED STRONG MID TO UPPER LEVEL LOW AROUND NORTHERN MEXICO. GOOD LOW TO MID LEVEL FLOW WAS NOTED ACROSS THE LOWER MISSISSIPPI VALLEY AHEAD OF THIS FEATURE.
341 PM CST TUE MAR 8 2016 Several rounds of showers and possibly a few thunderstorms will affect mainly the southeast part of the forecast area over the next few days as a slow moving upper low digs south across northern Mexico before eventually lifting northeast across Texas into Arkansas by the end of the week into the first part of the weekend. Low rain chances will continue through the weekend as another upper low moves more quickly across the area.
TONIGHT THROUGH WEDNESDAY A PACIFIC LOW PRESSURE TROUGH OVER IDAHO AND WESTERN MONTANA HAS PRODUCED A LINE OF SHOWERS ACROSS EASTERN IDAHO MOVING INTO WESTERN WYOMING. BUT THE CLOUD COVER SHOULD REMAIN AS ANOTHER PACIFIC TROUGH MOVES INTO WESTERN IDAHO. IN THE LOWER ELEVATIONS EAST OF THE CONTINENTAL DIVIDE THE SHOWERS WILL BE RAIN.
A STRONG LOW PRESSURE SYSTEM MOVING ACROSS SONORA MEXICO WILL BRING ISOLATED TO SCATTERED SHOWERS TO THE AREA TODAY. EXPECT MUCH COOLER TEMPERATURES THIS AFTERNOON FOLLOWED BY FREEZING TEMPERATURES IN THE EASTERN VALLEYS TONIGHT. ISOLATED SHOWER ACTIVITY THIS MORNING ACROSS SE AZ AS UPPER LOW MOVES ACROSS SONORA MEXICO. COLDER OVERNIGHT LOW TEMPERATUERS WITH WIDESPREAD FREEZING AND LOCALIZED SUB-FREEZING TEMPERATURES ANTICIPATED IN THE VALLEYS OF EASTERN SANTA CURZ. A LOW PRESSURE SYSTEM WILL TRACK EASTWARD TO OUR SOUTH ACROSS SONORA MEXICO TODAY.
1111 AM MST TUE MAR 8 2016 18Z TAF CYCLE A DEEP LOW PRESSURE SYSTEM WILL CONTINUE TO TRACK WELL SOUTH OF NEW MEXICO. YET SOME PRECIPITATION WILL STILL DEVELOP OVER THE STATE AS A SURFACE COLD FRONT SLIDES IN. THE FOCUS FOR SHRASN/TSRA WILL BE ALONG THE INTERFACE OF THE CENTRAL MOUNTAIN CHAIN OF NEW MEXICO AND THE HIGH PLAINS WITH A SECONDARY FOCUS OVER THE SOUTHWESTERN TO SOUTH CENTRAL MOUNTAINS OF THE STATE. AN UPPER LEVEL LOW PRESSURE SYSTEM PASSING SOUTH OF NEW MEXICO WILL DRAW A MOIST BACK DOOR COLD FRONT THROUGH THE AREA TODAY.
Partly to mostly cloudy skies will be found across southern KY as cloudiness associated with a slow moving upper level low impacts the region. Still could see a few hit or miss showers across southern KY this afternoon, therefore the low PoPs still look good at this point. An upper low over Arkansas this morning will drift slowly southeastward to Alabama by the end of the short term. Shower coverage will wane this evening as the sun sets, and should be lower still tomorrow as the low drifts away. We got a degree or two warmer yesterday than expected, so will go on the warm side of guidance for temps today and tomorrow with highs generally in the 69-74 degree range.
1242 PM EDT THU APR 14 2016 A PRESSURE RIDGE WILL EXTEND INTO THE REGION FROM THE NORTH THROUGH THE WEEKEND. SLIGHTLY COOLER THAN NORMAL TEMPERATURES EXPECTED THROUGH FRIDAY WITH A CHANCE OF SHOWERS MAINLY ACROSS THE SOUTH MIDLANDS AND CSRA. DRIER AND WARMER CONDITIONS EXPECTED OVER THE WEEKEND. NEARLY STATIONARY UPPER LOW OVER THE MID TO LOWER MISSISSIPPI VALLEY. DRY HIGH PRESSURE RIDGING DOWN THE EASTERN SEABOARD WITH STALLED FRONT WELL TO OUR SOUTH. SO LOWERED POPS SLIGHTLY A DEVELOPING COASTAL TROUGH AND APPROACH OF UPPER LEVEL LOW OVER THE GULF COAST REGION WILL RESULT IN A CHANCE OF SHOWERS MAINLY ACROSS THE CSRA THROUGH FRIDAY NIGHT. HOLDING THE CLOSED LOW JUST TO THE WEST. ALTHOUGH MAY BE COOLER IN THE CSRA.
1047 AM EDT THU APR 14 2016 A PRESSURE RIDGE WILL EXTEND INTO THE REGION FROM THE NORTH THROUGH THE WEEKEND. SLIGHTLY COOLER THAN NORMAL TEMPERATURES EXPECTED THROUGH FRIDAY WITH A CHANCE OF SHOWERS MAINLY ACROSS THE SOUTH MIDLANDS AND CSRA. DRIER AND WARMER CONDITIONS EXPECTED OVER THE WEEKEND. NEARLY STATIONARY UPPER LOW OVER THE MID TO LOWER MISSISSIPPI VALLEY. DRY HIGH PRESSURE RIDGING DOWN THE EASTERN SEABOARD WITH STALLED FRONT WELL TO OUR SOUTH. SO LOWERED POPS SLIGHTLY A DEVELOPING COASTAL TROUGH AND APPROACH OF UPPER LEVEL LOW OVER THE GULF COAST REGION WILL RESULT IN A CHANCE OF SHOWERS MAINLY ACROSS THE CSRA THROUGH FRIDAY NIGHT. HOLDING THE CLOSED LOW JUST TO THE WEST. ALTHOUGH MAY BE COOLER IN THE CSRA.
1225 PM EDT THU APR 14 2016 HIGH PRESSURE WILL BUILD OVER THE REGION THROUGH THE UPCOMING WEEKEND.
429 AM PDT THU APR 14 2016 A fast moving and relatively cold low pressure system will bring rain to the area with mountain snow and gusty winds. Warmer and drier Friday and into the weekend. A cold low pressure system with a band of moderate to locally heavy precipitation, generally around I80 southward, is moving through the area this morning. This is also beginning to spread into the Highway 50 corridor. Gusty winds over the northern Sacramento Valley peaked late in the evening with the passage of the cold front, so the Wind Advisory was cancelled. Precipitation should taper off by early this evening and high pressure will build into the area for Friday. Slightly warmer with breezy to windy northerly winds likely during the day for the valley.
