241 PM CDT TUE APR 26 2016 Isolated to scattered showers have started to develop across our northern counties in the warm unstable air south of a warm front. Models indicate the warm front will continue to meander near the Interstate 64 corridor into tonight. By late tonight, the eastward progression of a cold front will bring a surge of moisture/showers and thunderstorms into our western counties. The approach and passage of the cold front will keep widespread showers and storms across our entire region through the day Wednesday and into Wednesday evening.
Best bet will be over our eastern CWA, where the higher surface dewpoints will hang around the longest.
THE PREVAILING THOUGHT OVER THE LAST COUPLE OF DAYS WAS THAT THE NEXT PLAINS LOW PRESSURE SYSTEM WOULD TRACK BY TO OUR SOUTH WITH LITTLE FANFARE ACROSS OUR NECK OF THE WOODS (EXCEPT FOR PERHAPS SOME CLOUDINESS). THIS IS DESPITE THE BLOCKING UPPER LEVEL RIDGE TO OUR NORTH WHICH APPEARS TO HOLD ITS GROUND.
A WARM FRONT STRETCHED ACROSS THE REGION FROM ROUGHLY ST FRANCIS KANSAS TO COLBY TO HILL CITY. TEMPERATURES NORTH OF THE WARM FRONT ARE IN THE UPPER 40S TO LOW 60S WITH NORTHEAST WINDS. TEMPERATURES SOUTH OF THE WARM FRONT HAVE CLIMBED INTO THE UPPER 60S TO LOW 70S WITH SOUTH WINDS BEING OBSERVED. FORECAST GUIDANCE IS OVER-PREDICTING THE LOW LEVEL MOISTURE. THE BETTER CHANCE FOR THUNDERSTORMS ARRIVES THIS EVENING AS A COLD FRONT OVER NORTHEAST COLORADO SURGES SOUTHEAST THROUGH THE REGION. THIS FRONT WILL BRING MUCH COOLER TEMPERATURES AND NORTHWEST WINDS OF 20-30 MPH. A FEW SHOWERS WILL LINGER IN SOUTHWEST NEBRASKA WEDNESDAY EVENING BEFORE ENDING AS THE UPPER LOW PULLS AWAY TO THE NORTH.
TEMPERATURES THIS MORNING ARE COOLER COMPARED TO PREVIOUS DAYS, GENERALLY IN THE 40S FOR MOST LOCATIONS AND A FEW MID/UPPER 30S IN THE HIGHER ELEVATIONS AND DOWN IN SOUTHERN INTERIOR VALLEYS. TEMPS ARE CLOSE TO YESTERDAY'S VALUE ALTHOUGH NAPA IS RUNNING 7 COOLER THAN YESTERDAY AND WILL LIKELY DROP INTO THE MID TO UPPER 30S. TODAY WILL BE GENERALLY SUNNY WITH HIGHS IN THE MID 60S TO THE LOWER 70S. A RIDGE OF HIGH PRESSURE WILL BUILD BACK TO THE COAST BY THE END OF THE WEEK WHICH WILL LEAD TO MUCH WARMER CONDITIONS.
119 PM EDT TUE APR 26 2016 AVIATION CLOUDY AND CHILLY WEATHER CAN BE EXPECTED TODAY BEHIND AN EXITING LOW PRESSURE SYSTEM. HIGH PRESSURE WILL BUILD IN TONIGHT AND BRING CLEARING SKIES WITH SOME PATCHY FROST POSSIBLE.
HIGH TEMPERATURES TOMORROW WILL GENERALLY BE IN THE LOWER TO MID 80S AND LOWS TONIGHT NEAR 60.
WITH SLIGHTLY WARMER TEMPS TO THE NORTH AND COOLER TO THE SOUTH. OTHERWISE WEAK UPPER LOW OVER THE FA GRADUALLY WASHES AS RIDGING BUILDS INTO THE REGION.
ALL THIS IS TYING NICELY INTO THE SHORT-RANGE HIGH-RES MODELS POINTING TO MAYBE A FEW SHOWERS/STORMS MAINLY OVER THE LOWER ATCHAFAYALA BASIN (KLIX SOUNDING SHOWED BETTER MOISTURE IN PLACE THIS MORNING). /ISSUED 318 AM CDT TUE APR 26 2016/ WX MAP SHOWS HIGH PRESSURE TO THE EAST WITH LOW PRESSURE ACROSS THE PLAINS. THIS WILL BRING A SFC TROF. LOOKING FOR FINAL CLEARING BY TUE WITH COOLER CONDITIONS AS WELL. DML THE COMBINATION OF HIGH PRESSURE CENTERED OVER THE ATLANTIC OFF THE CAROLINA COAST AND A SERIES OF LOW PRESSURE SYSTEMS DEVELOPING OVER THE PLAINS STATES WILL MAINTAIN AN ONSHORE FLOW OVER THE COASTAL WATERS THROUGH THE PERIOD.
UPPER LOW TRACKING THROUGH SOUTHERN WYOMING AT THIS TIME. MODELS ALL CONSISTENT IN STRETCHING TROUGH AXIS AS DOUBLE BARRELLED ENERGY REGIONS ROTATE THROUGH TROUGH.
SUBJECTIVE 12Z UPPER AIR ANALYSIS INDICATES UPPER LOW CENTERED ON THE WY/CO BORDER. UPPER-LEVEL JET STREAK HAD ROUNDED THE BASE OF THE LOW AND ALSO HAD WEAKENED. WITH WARM FRONT EXTENDING ALONG THE KS-NEB BORDER AND DRYLINE FROM NORTH CENTRAL KS THROUGH WESTERN OK/CENTRAL TX. AHEAD OF THE DRYLINE AND WARM FRONT. AND LIKELY SYNOPTIC WARM FRONT EVIDENT FROM NEAR KCNK TO NEAR KMYZ TO NORTH OF KFNB TO NEAR KICL. WITH GHOST OF A SYNOPTIC WARM FRONT INTO SOUTHEAST NEB. ALONG AND SOUTH OF THE SYNOPTIC WARM FRONT. NORTH OF THE WARM FRONT. UPPER LOW IS PROGGED TO ROTATE INTO CENTRAL NEB ON WEDNESDAY. RISK OF STORMS SHOULD WANE EARLIER IN THE EVENING AS COOLER AIR DRAWS DOWN INTO EASTERN NEB/WESTERN IA BEHIND THE EXITING LOW.
WITH THE HIGHEST SNOWFALL TOTALS ACROSS THE ADIRONDACKS AND THE SUMMITS OF THE SOUTHERN GREEN MOUNTAINS. THIS LOW PRESSURE SYSTEM WILL PASS QUICKLY WITH PRECIPITATION ENDING DURING THE EARLY TO MID AFTERNOON HOURS WITH PARTIAL CLEARING FROM WEST TO EAST LATE IN THE DAY. QUIET AND MAINLY CLEAR TONIGHT AS HIGH PRESSURE RIDGES SEWD FROM NRN ONTARIO. RIDGE OF HIGH PRESSURE AT THE SURFACE BUILDS OVER THE NORTH COUNTRY FOR THE REST OF THE WORK WEEK. MID LEVEL TROUGH WILL KEEP SOME CLOUDS OVER THE REGION WITH ONLY SLIGHT CHANCES FOR PRECIPITATION AS EMBEDDED VORT MOVES THROUGH THE BASE OF TROUGH WEDNESDAY NIGHT.
WV imagery indicates a strong closed off upper level low lifting northeast across northern Colorado into southeast Wyoming and southwest Nebraska. Near the surface, an area of low pressure is situated across west central Kansas with an attendant warm front extending east-northeast into northeast Kansas. As this occurs, warm front will lift to the north of I-70 while the dryline moves into south central Kansas. A Pacific cold front is expected to move out into southwest Kansas to near the Highway 283 corridor this afternoon. As the upper low continues to move east overnight, there will be at least a slight chance for showers and thunderstorms across portions of west central and southwest Kansas later tonight into Wednesday morning associated with the mid level deformation zone.
648 PM EDT TUE APR 26 2016 COLD FRONT MOVING INTO CENTRAL OHIO AND SOUTHWEST PA WILL REACH THE OHIO RIVER VALLEY OVERNIGHT. HIGH PRESSURE WILL RIDGE INTO THE AREA FROM CENTRAL CANADA ON WEDNESDAY.
OTHERWISE RAIN CHCS RETURN TO THE FCST FRI (IN RESPONSE TO THE NEXT UPPER TROF/LOW DIGGING AOA THE FOUR CORNERS).
FAIRLY STRONG HIGH PRESSURE WILL KEEP A GENERALLY EASTERLY FLOW OVER THE CWA, WITH THE SEA AND LAKE BREEZES TRYING TO DEVELOP EACH AFTERNOON.
Except for initial development that might affect areas generally west of Highway 75 late afternoon and evening, there should be an increasing tendency toward more linear structures this far east, given more northerly storm movements with the approach of the upper low. Much of the high resolution guidance has favored a later arrival of storms in eastern Oklahoma and western Arkansas, with much of the activity in this part of the country likely to be after dark.
THE BEST CHC OF DVLPMNT STILL LOOKS TO BE ACROSS THE CENTRAL AND N PARTS OF THE CWA LATER THIS AFTERNOON/EVENING WHERE THE STRONGER LOW LEVEL CONVERGENCE IS PROGD TO BE AS WELL THE HIGHEST CAPE/LOWEST CIN. WEAK RIDGING WILL BUILD ACROSS S TX IN ITS WAKE WED AFTERNOON INTO WED NIGHT BRINGING DRIER MID/UPPER LEVELS ACROSS THE REGION.
A showery pattern will continue for the Northern Rockies through much of this week as a broad trough of low pressure remains overhead.
AS THE TROUGH SHIFTS INLAND, CHANCES FOR PRECIPITATION WILL DIMINISH WEDNESDAY NIGHT.
336 PM EDT TUE APR 26 2016 COLD FRONT MOVING INTO CENTRAL OHIO AND SOUTHWEST PA WILL REACH THE OHIO RIVER VALLEY OVERNIGHT. HIGH PRESSURE WILL RIDGE INTO THE AREA FROM CENTRAL CANADA ON WEDNESDAY.
CLOSED LOW OVER THE GULF OF ALASKA AND SOUTHEAST CANADA. UPPER LEVEL LOW CURRENTLY CENTERED ACROSS EASTERN WY WILL TRACK NORTH INTO EASTERN MONTANA TONIGHT. AS THE WARMER MOIST AIR HAS REMAINED WELL SOUTH IN KANSAS. STILL IT IS POSSIBLE THAT A SEVERE STORM CONTAINING LARGE HAIL COULD DEVELOP NORTH OF THE WARM FRONT ACROSS SOUTHWEST INTO CENTRAL NEBRASKA THIS EVENING.
This will bring warmer temperatures to the region with highs in the mid to upper 80s.
331 PM EDT TUE APR 26 2016 A COLD FRONT WILL DROP ACROSS THE REGION THROUGH THIS EVENING.
Additional showers and thunderstorms could develop late this evening and overnight ahead of the aforementioned progressive Plains MCS in response to the LLJ and WAA along north of the retreating outflow boundary/warm front composite. The combination of the east-northeast rotating short wave trof and large scale ascent, and the attendant advancing cold front should result in thunderstorm development along/ahead of the cold front by mid afternoon. Coverage should then increase through the remainder of the afternoon, with storms persisting into the evening as the front and trof progress east.
657 PM EDT TUE APR 26 2016 A COLD FRONT WILL MOVE ACROSS THE AREA THIS EVENING THEN BECOME STATIONARY ACROSS SOUTHERN VIRGINIA WEDNESDAY NIGHT. HIGH PRESSURE BUILD IN ITS WAKE AND HOLDS THROUGH THE WEEKEND. WL HV A CPL OF COOLER DAYS. WARM FRONT WILL PUSH NORTH ON SUN BRINGING BACK THE CHANCE OF PRECIP. THEN SUB-VFR CONDITIONS SUN AS WARM FRONT LIFTS NORTH OVER OUR REGION BRINGING THE CHANCE FOR ADDITIONAL SHOWERS.
538 PM EDT TUE APR 26 2016 A COLD FRONT WILL DROP ACROSS THE REGION THROUGH THIS EVENING.
A WARM FRONT STRETCHED ACROSS THE REGION FROM ROUGHLY ST FRANCIS KANSAS TO COLBY TO HILL CITY. TEMPERATURES NORTH OF THE WARM FRONT ARE IN THE UPPER 40S TO LOW 60S WITH NORTHEAST WINDS. TEMPERATURES SOUTH OF THE WARM FRONT HAVE CLIMBED INTO THE UPPER 60S TO LOW 70S WITH SOUTH WINDS BEING OBSERVED. FORECAST GUIDANCE IS OVER-PREDICTING THE LOW LEVEL MOISTURE. THE BETTER CHANCE FOR THUNDERSTORMS ARRIVES THIS EVENING AS A COLD FRONT OVER NORTHEAST COLORADO SURGES SOUTHEAST THROUGH THE REGION. THIS FRONT WILL BRING MUCH COOLER TEMPERATURES AND NORTHWEST WINDS OF 20-30 MPH.
AN UPPER LEVEL RIDGE CENTERED NEAR CENTRAL AMERICA EXTENDS NORTH INTO THE EASTERN UNITED STATES. A BROAD HIGH PRESSURE SYSTEM EXTENDS WEST ACROSS THE FLORIDA PENINSULA.
155 PM EDT TUE APR 26 2016 HIGH PRESSURE WILL REMAIN OFFSHORE THE SE COAST THROUGH WEDNESDAY.
LOW PRESSURE WILL SPLIT OFFSHORE AND SHIFT SOUTHEAST INTO OREGON TONIGHT AND WEDNESDAY.
HIGH TEMPERATURES TODAY WILL BE IN THE 60S, EXCEPT IN THE LOWER 40S TO UPPER 50S IN THE MOUNTAINS.
ANOTHER PARTLY CLOUDY TO MOSTLY SUNNY DAY ACROSS THE EASTERN TN VALLEY AND SOUTHERN APPALACHIANS AS UPPER RIDGE HOLDS STRONG. LOWS WILL BE WARMER IN THE UPPER 50S TO NEAR 60S.
211 PM EDT SAT SEP 10 2016 Hydro A cold front will track eastward through the Great Lakes Region today.
A large upper level trough axis will slowly move east across the area today. with a ridge axis building over the area tonight and Sunday. Highs on Sunday to be warmer with the warm air advection pushing high temperatures into the mid 60s to mid 70s. Summary: A cold front passage will bring cooler weather early this week, then high pressure will provide sunny and seasonal weather for the middle of the week. Warmer weather will return for the latter half of the week.
With northwesterly flow aloft and at the surface today, temperatures were much cooler than the seasonal normals with highs only reaching into the middle 70s. As the mid- level trough quickly lifts into the New England area overnight, mid- level flow will become more zonal for Sunday. The combination of light winds and clear skies will support decent radiational cooling with lows dropping into the low 50s tonight. With winds shifting to the south and becoming a bit breezy across north central KS with gusts of 20- 30mph, expect slightly warmer conditions with afternoon highs in the upper 70s to low 80s from east to west.
342 PM CDT SAT SEP 10 2016 At 3 PM, an upper level trough of low pressure was located over eastern Wisconsin. This precipitation should end late this afternoon as the trough moves east into Michigan. First, the winds aloft will be increasing as the ridge moves off to the east late tonight. 12z deterministic models show that mid and high clouds, associated with warm air advection ahead of a short wave trough moving out of Alberta, will be moving into the forecast area.
/issued 301 AM CDT SAT SEP 10 2016/ The leading edge of thunderstorms associated with the cold front has moved south of the Red River leaving light rain for several hours behind it.
A ridge will slide south and east to the Big Bend area tonight with an old closed low closed along the southern CA coast with begin funneling moisture north and into the four corners region tonight and Sunday.
Main focus through this evening will continue to revolve around severe storm chances as a cold front moves across the region. Presently, the cold front is moving into Louisville. By tomorrow, high pressure builds in behind the exiting front, with sunny skies returning. Cooler weather will prevail with highs in the 70s, making for a very pleasant end to the weekend. The drier airmass will allow for a cooler night Sunday night as lows settle well into the 50s.
Water vapor loops shows upper trough moving southeastward across the Upper Midwest and Central Plains. Mostly sunny skies, cooler temperatures and a drier airmass will make for a great Saturday with highs mainly in the mid 70s. High pressure ridge will be across eastern KS this evening with light winds and mostly clear skies. As the high moves off to the east/southeast tonight, southerly winds should begin to pick up over north central KS. However, with the movement of the high, and an otherwise pretty dry airmass, temporal window for dense fog formation should be relatively small.
114 PM CDT SAT SEP 10 2016 The well-advertised cold front has pushed through the remainder of southeastern Kansas early this morning, and post-frontal stratiform rainfall should clear the far southeastern Kansas counties by 10 or 11 UTC. The parent upper trough over the Upper Midwest will translate eastward to the Great Lakes/Ohio Valley by this evening, with high pressure building into Kansas with cooler and drier air for today.
Westerly flow with high pressure to the south will result in deep mixing but not much winds aloft to translate to the surface. With warmer temperatures and not much additional humidity, could see conditions approach Red Flag, although peak winds are marginal for said headlines.
As we get into the mid-afternoon hours, an axis of instability is progged to push into our northwest counties just ahead of the cold front. So, by late this afternoon, we can expect a pre-frontal trough to help spark some scattered thunderstorm segments in the form of a very broken line.
A low pressure system centered west-southwest of the Dry Tortugas remains readily apparent on visible satellite loops. A sharp upper level ridge reaches north into the central Gulf Coast, meanwhile, to its east, an upper level trough has carved out lower heights deep into the Bahamas. Thereafter, the lower troposphere will feature light ENE/ESE steering, plentiful theta-e, weak inhibition, with a nondescript upper level pattern.
As of mid-afternoon, a strong surface cold front extended from central Indiana through western and central Kentucky down into portions of northwestern TN. Drier and cooler air will surge into the region later this evening and overnight with steady northwest winds. Sunday will be a very pleasant, early fall day across southern Indiana and central Kentucky with low humidity, temperatures in the 70s and overall light winds as the center of high pressure moves overhead.
244 PM EDT Sat Sep 10 2016 A strong cold front will cross tonight, bringing strong thunderstorms with it. A cooler and less humid environment is forecast for Sunday. There have been no major changes to the thinking for the approach and passage of a strong cold front tonight. Freezing/wet bulb zero heights look too high for much hail, and tornado threat is minimal. A refreshing air mass change is expected for this period behind the boundary with high pressure in command.
215 PM MDT SAT SEP 10 2016 Current surface map places high pressure over the central plains, with trof over Montana/Wyoming. Upper trof digs across the Rockies tonight into Sunday, with increasing mid/upper level southwest flow. Low level thermal ridge builds into the area for Sunday. Models in decent agreement with cold front slipping through northeast Wyoming/western South Dakota Sunday night. Positively tilted trough will stretch across the northern CONUS for the beginning of the week.
258 PM CDT SAT SEP 10 2016 H5 hand analysis from earlier this morning had a trough of low pressure extending from the arrowhead of Minnesota south to southwestern Oklahoma. At the surface, high pressure was located across western Kansas. For tonight: High pressure will build east into the Ozarks. Warmer air will push into western and north central Nebraska overnight, however dry boundary layer air will still persist.
445 PM MDT SAT SEP 10 2016 Current surface map places high pressure over the central plains, with trof over Montana/Wyoming. Upper trof digs across the Rockies tonight into Sunday, with increasing mid/upper level southwest flow. Low level thermal ridge builds into the area for Sunday. Models in decent agreement with cold front slipping through northeast Wyoming/western South Dakota Sunday night. Positively tilted trough will stretch across the northern CONUS for the beginning of the week.
(Issued 1033 AM CDT SAT SEP 10 2016) Temperatures across the Tennessee Valley currently range in the lower to middle 80s, with a few spots flirting with the upper 80s at this hour. Clouds are generally increasing from the west ahead of an approaching cold front, with the bulk of the limited precip (for now) associated with it still west of our CWFA. The highest POPs will remain over the NWrn zones, with the lowest POPs in the S/Ern zones. 12 For 18Z TAFs: VFR conditions are expected with isolated -SHRA activity that is occurring across portions of N AL as a cold front approaches from West TN/MS River area.
As for temperatures, the atmosphere is not expected to be modified greatly so daytime temperatures for Sunday should be fairly similar to today with highs in the low to mid 90s. As for overnight lows, temperatures should fall into the low to mid 70s again, with near 80 degrees along the immediate coast.
140 PM EDT SAT SEP 10 2016 A cold front will sweep across the area this afternoon. High pressure will build in for the early part of the week.
An open trough axis will continue to pull away from the north central CONUS with a general zonal pattern in its wake for the rest of the weekend. This synoptic scale pattern will lead to a deepening leeside trough across eastern Colorado. The rising heights and downslope momentum will result in a much warmer lower troposphere and this will be seen in the surface temperatures as well. Temperatures will moderate Sunday back into the 80s as lee troughing resumes.
A narrow line of storms has developed along a cold front across weatern KY and West TN. Highs in the lower to mid 80s and afternoon dewpoints in the 50s should make for a pleasant day. Cold front will have moved southeast of forecast area with slightly cooler and drier air mass across the region sunday night. Strong upper level ridge that was across region this past week will stay south and east.
Overview: Short wave trough axis now working into the western Great Lakes with entrance region of upper jet streak stretching from the western Great Lakes into Canada. Cold front and leading line of heavy showers/isolated thunder down into Saginaw Bay. Sunday: High pressure and drier air overspreads the region.
Upper air analysis this morning showed a weak low over east Texas with a deep trough over the Great Plains. At the surface, a cold front was stretched from La Grange to San Antonio to Pandale. The upper low will drift slowly toward the east beneath a broad ridge during this period.
First in a series of cold fronts already exiting the southeast at 05z with a secondary cool front/wind shift over southern Minnesota. The second boundary has not yet realized the cooler air aloft but is a reflection of an upper level H850 cool front located from near International Falls southwest to near Huron at 00z. In the wake of the second boundary a reinforcing cooler and drier airmass over the Northern Plains will move southeast into Iowa today through tonight. Highs will be very comfortable and even cooler than our normal highs in the mid 70s north to upper 70s south. Today we will end up about 5 to 7 degrees cooler across the board.
High temps on Sun are expected to be around or slightly above normal in the high valleys and around ten degrees above average ovr the sern plains. Early Mon a cold front will move thru ern CO, with sfc winds becoming easterly for the afternoon hours. An upper level trof wl be ovr the western states on Mon and moisture is expected to be drawn up into wrn CO from the south. Temps on Mon will be several degrees cooler across the sern plains. For Tue and Wed, the upr trof is expected to remain ovr the western U. with a closed low ovr nrn NV. Thu night another front drops south into the forecast area as the low and upr trof track eastward.
A cold front currently across central Indiana will move on to the east.
Cold front has moved south of area TAF locations this morning. May see some clearing of the lower ceilings by mid to late afternoon. Busy night across West Texas/SE NM as convection continues behind a cold front movg south. /issued 359 AM CDT SAT SEP 10 2016/ Currently, a cold front is pushing southward courtesy of an upper trough over the Upper Midwest and has gotten to the northern Permian Basin. Temperatures behind the front will be much cooler with highs today only expected to get to the 70s across much of the area. After cooler temperatures tonight, high temperatures tomorrow will rebound into the 80s across most places. Rain and thunderstorm chances Sunday will be south and west of the Pecos River mostly along the higher terrain where the front may be lingering still.
As the high shifts over the Midwest later tonight, the pressure gradient will strengthen with breezy downslope wind possible on the lee side of the Sisseton Hills. The southerly winds will bring warmer and dry air into the region on Sunday with highs exceeding 80 degrees for most location.
Even warmer temperatures are expected on Sunday as the flow aloft veers into the southwest a bit ahead of the next upper level trough and associated cold front moving into Montana. Gusts around 40 to 45 MPH are expected Sunday ahead of this cold front mainly along and west of the Laramie Range.
The cold front is quickly moving across eastern portions of the PAH forecast area this afternoon. The cold front and associated convection will clear our region by 00z. Drier air will filter in behind the front with models quickly building high pressure into middle Mississippi River valley.
Latest sfc analysis indicates that this activity is just along and ahead of the main cold frontal boundary. In the ext fcst, weak w-e ridging will prevail. Late in the extended, we will see a pattern change as stronger upper troughing and a frontal boundary moves our way.
Gusty northeast winds, mountain snow and much cooler. A significant change in the weather is expected to begin tomorrow morning as a deep upper level low pressure system and Canadian cold front swing through the region. Snow levels will lower in the afternoon and evening along the Continental Divide to around 5000 feet, which will allow for another round of accumulating snow in the higher terrain. Due to lowering freezing levels, any thunderstorms that form Sunday afternoon will be capable of producing small hail, as well as brief heavy rain.
/Issued 735 AM EDT SAT SEP 10 2016/ Ridging at the surface and aloft will dominate the forecast area through today. The upper ridge weakens and gets suppressed to the south overnight as an upper trough moves through the Great Lakes and Ohio Valley. Expect another hot day similar to the past few but max temperatures should be a few degrees cooler mainly northwest on Sunday.
311 PM CDT SAT SEP 10 2016 A short wave trough moving across the mid and upper Mississippi Valleys this afternoon will push east across the Great Lakes and Ohio Valley regions tonight and into the northeast conus on Sunday. This feature will push a weakening cold front south into the region on Sunday which will stall out across the CWA through the early part of the week before becoming diffuse. Rain chances will lower a bit during the mid week period as the aforementioned features weaken/dissipate while upper level ridging builds over the Gulf Coast and southeast.
329 PM EDT SAT SEP 10 2016 High pressure remains anchored over the southeast states into tonight. A cold front crosses the area Sunday.
