Thestrongest part of this MCS is traveling along a diffuse boundary.South of this boundary, temperatures continue to slowly rise to near80 F despite substantial cloud cover. Breaks in the clouds do existhowever, from near the Twin Cities into western WI.Objective analysis indicates MLCAPE of 1500-2000 J/kg ahead of theMCS, which should support a continues damaging wind threat. The 18ZMPX sounding shows the effects of cooler, stabilizing outflow airfrom convection over IA, and this will likely limit southward growthpotential with the ongoing MCS. Embedded areas of rotation cannot beruled out within the arcing line of convection, though effective SRHahead of the MCS is currently only averaging around 100 m2/s2...Jewell.. 08/28/2021...Please see www.spc.noaa.gov for graphic product...ATTN...WFO...MQT...GRB...DLH...ARX...MPX...LAT...LON 46289283 46729165 46989074 46759032 46249000 4569899745369041 45199157 45189320 45259367 45639341 4586932946039332 46289283WOUS20 KWNS 281913WWASPCSPC WW-A 281915MNZ000-WIZ000-LSZ000-282040-STATUS REPORT ON WW 468SEVERE WEATHER THREAT CONTINUES RIGHT OF A LINE FROM 30 E MSP TO60 NNE MSP TO 50 SW DLH TO 25 SSW DLH TO 20 ENE DLH...JEWELL..08/28/21ATTN...WFO...DLH...MPX...&&STATUS REPORT FOR WT 468SEVERE WEATHER THREAT CONTINUES FOR THE FOLLOWING AREASWIC003-005-007-013-017-031-033-051-095-099-107-109-113-129-282040-WI.

Occasionally manualintervention is necessary to address quality control and consistency issues. Inthese cases, forecasts are manually drawn but a full discussion is not issued.The notation for the categorical forecast indicated on the maps is the same asthat in the tables: A-above N-near normal B-belowThe temperature map shows regions with > 33% chance of being warmer (orange,"A"), colder (blue, "B"), or close to (unshaded, "N"). Historical averagevalues for the calendar period of the forecast (dashes, "f"). Labels on theshaded lines give the probability (> 33%) of the more likely category (B or A).Probability of N is always < 40%.The precipitation map shows regions with > 33% chance of being wetter (green,"A"), drier (tan, "B"), or close to (unshaded, "n"). Historical median valuesfor the calendar period of the forecast (dashes, "inches"). Labels on theshaded lines give the probability (> 33%) of the more likely category (B or A).Probability of N is always < 40%.In the southwest and other climatologically dry regions - there will be agreater than 33.3% chance of no precipitation and occasionally even a normal(i.e. Median) value of zero - especially during the dry seasons. In such casesa forecast of near normal is effectively a forecast of little or noprecipitation.The climate prediction center uses 1981-2010 base period means fortemperature...precipitation...and 500-hpa heights as reference in the climateoutlooks.Analogs to the 5 day mean observed pattern centered 3 days ago (D-3)for the region from 20N to 70N latitude and 175E to 60W longitudeinclude the 5 day periods centered on the following dates:20020831 - 19800830 - 19990904 - 20030911 - 19730808Analogs to the 7 day mean observed pattern centered 4 days ago (D-4)for the region from 20N to 70N latitude and 175E to 60W longitudeinclude the 7 day periods centered on the following dates:20020830 - 19730808 - 20030910 - 20020809 - 198008316 TO 10 DAY OUTLOOK TABLEOutlook for Sep 03 - 07, 2021STATE TEMP PCPN STATE TEMP PCPN STATE TEMP PCPNWASHINGTON A B OREGON A B NRN CALIF N BSRN CALIF N N IDAHO N B NEVADA A BW MONTANA N B E MONTANA N A WYOMING N AUTAH A N ARIZONA N N COLORADO A ANEW MEXICO A N N DAKOTA B A S DAKOTA N ANEBRASKA A A KANSAS A N OKLAHOMA A BN TEXAS A B S TEXAS A N W TEXAS A BMINNESOTA N N IOWA N N MISSOURI A NARKANSAS A B LOUISIANA A A WISCONSIN N NILLINOIS N N MISSISSIPPI A N MICHIGAN N AINDIANA A N OHIO N N KENTUCKY A NTENNESSEE A N ALABAMA A N NEW YORK B AVERMONT B A NEW HAMP B A MAINE B AMASS N A CONN N A RHODE IS N APENN N A NEW JERSEY N A W VIRGINIA A NMARYLAND N N DELAWARE N N VIRGINIA A NN CAROLINA A N S CAROLINA A N GEORGIA A NFL PNHDL A N FL PENIN A B AK N SLOPE N AAK ALEUTIAN A B AK WESTERN A B AK INT BSN A AAK S INT A N AK SO COAST A N AK PNHDL A A8 TO 14 DAY OUTLOOK TABLEOutlook for Sep 05 - 11, 2021STATE TEMP PCPN STATE TEMP PCPN STATE TEMP PCPNWASHINGTON A B OREGON A B NRN CALIF A BSRN CALIF A N IDAHO A B NEVADA A BW MONTANA A B E MONTANA N B WYOMING A BUTAH A B ARIZONA A B COLORADO A BNEW MEXICO A N N DAKOTA N N S DAKOTA B BNEBRASKA N B KANSAS A N OKLAHOMA A NN TEXAS A A S TEXAS A A W TEXAS A NMINNESOTA B N IOWA B N MISSOURI N AARKANSAS N A LOUISIANA A A WISCONSIN B NILLINOIS B A MISSISSIPPI N A MICHIGAN N AINDIANA B A OHIO B A KENTUCKY B ATENNESSEE B A ALABAMA N A NEW YORK B AVERMONT N A NEW HAMP N A MAINE N AMASS N A CONN N A RHODE IS N APENN N A NEW JERSEY N A W VIRGINIA N AMARYLAND A A DELAWARE A A VIRGINIA A AN CAROLINA A A S CAROLINA A N GEORGIA A AFL PNHDL A N FL PENIN A N AK N SLOPE N NAK ALEUTIAN A B AK WESTERN A N AK INT BSN A AAK S INT A N AK SO COAST A B AK PNHDL A ALEGENDTEMPS WITH RESPECT TO NORMAL PCPN WITH RESPECT TO MEDIANA - ABOVE N - NEAR NORMAL A -NWUS20 KWNS 281755STADTSSPC TORNADO AND SEVERE THUNDERSTORM REPORTSUNOFFICIAL - FOR OFFICIAL REPORTS, SEE PUBLICATION 'STORM DATA'FOR 06CST FRI AUG 27 2021 THRU 06CST SAT AUG 28 2021EVENT LOCATION REMARKS (CST)TIME.....TORNADO REPORTS..........TORNADO REPORTS..........TORNADO REPORTS.....1 *TORN 5 S CLEAR LAKE IA (6 SSW MCW) 27/1607TRAINED SPOTTER RELAYED REPORT TO EM OF BRIEF DMX/LSR 4307 9339TORNADO TOUCH DOWN WES2 *TORN 5 SSE CLEAR LAKE IA (5 S MCW) 27/1615TRAINED SPOTTER RELAYED REPORT TO COUNTY LAW DMX/LSR 4307 9334ENFORCEMENT OF BRIEF T3 *TORN 2 W MARBLE ROCK IA (24 ESE MCW) 27/1656ARX/LSR 4296 92914 *TORN 1 S MARBLE ROCK IA (27 ESE MCW) 27/1700DAMAGE IS EXTENSIVE SOUTH TO EAST-NORTHEAST OF ARX/LSR 4295 9287MARBLE ROCK.5 *TORN 4 SW CHARLES CITY IA (31 ESE MCW) 27/1709ARX/LSR 4303 92736 *TORN 2 SE MARBLE ROCK IA (28 ESE MCW) 27/1710LARGE ABOVE GROUND PROPANE TANKS WERE KNOCKED ARX/LSR 4294 9284OVER BY A TORNADO........LRG HAIL/STRONG WIND RPTS.............LRG HAIL/STRONG WIND RPTS......32 WNDG 4 NNE CROSS PLAINS WI (14 W MSN) 27/0835TREE SNAPPED OFF AT BASE.

The following information is based on satelliteimagery, weather observations, radar and meteorological analysis.Based on 1200 UTC surface analysis and satellite imagery through1745 UTC....SPECIAL FEATURES...Hurricane Ida is near 24.8N 86.1W 984 mb at 28/1500 UTC EDTmoving NW at 14 kt. Maximum sustained winds 75 kt gusts 90 kt.Estimated minimum central pressure is 984 mb. The maximum seaheights are 30 ft. Scattered moderate to strong convection isfound mainly from 24N-26N between 84W-87W. An outer band withnumerous moderate to strong Convection is also noted 100 nm E ofthe eye of the storm from 23N to 27N between 82W to 84W. On theforecast track, the center of Ida will move over the southeasternGulf of Mexico today and move over the central Gulf of Mexicotonight and early Sunday. Ida is then expected to make landfallalong the U.S. northern Gulf coast within the hurricane warningarea on Sunday, and then move inland over portions of Louisianaor western Mississippi later Monday. Rapid strengthening isforecast during the next 24 to 36 hours and Ida is expected to bean extremely dangerous major hurricane when it approaches thenorthern Gulf coast on Sunday. Weakening is expected after Idamakes landfall.

Environmental conditions areexpected to be only marginally conducive for further development.However, a tropical depression could still form within the nextcouple of days. By midweek, the system is forecast to be absorbedby a frontal system. The disturbance is expected to drifteastward through today, then accelerate northeastward Sundaytoward the central north Atlantic. This system has a mediumchance of tropical cyclone formation during the next 48 hours.Please refer to the NHC Tropical Weather Outlook atwww.hurricanes.gov for more details....TROPICAL WAVES...An Atlantic tropical wave has moved off the African coast along16W from 19N southward, moving W at 15 kt.
