A FRONT WILL REMAIN STATIONARY ALONG THE GULF COAST TONIGHT. A STORM SYSTEM WILL MOVE ACROSS TEXAS LATE TONIGHT AND TUESDAY MORNING... AND WILL INTERACT WITH THE FRONT. MOISTURE WILL BE PULLED NORTHWARD... WITH RAIN OVERSPREADING ARKANSAS ON TUESDAY. AS THE SYSTEM MOVES TOWARD THE SOUTHEAST UNITED STATES TUESDAY NIGHT...COLDER AIR WILL CHANGE RAIN TO SNOW TOWARD THE MISSOURI BORDER. IT APPEARS THE HEAVIEST SNOW WILL BE IN NORTHWEST SECTIONS OF THE STATE TOWARD FAYETTEVILLE...HARRISON...YELLVILLE AND JASPER. TWO TO THREE INCH SNOW ACCUMULATIONS ARE IN THE FORECAST IN THESE AREAS. OTHERWISE...HALF INCH TO INCH ACCUMULATIONS ARE EXPECTED NORTH OF BOONEVILLE...CLINTON AND BATESVILLE...WITH SOME SPOTS RECEIVING UP TO TWO INCHES. DATA HAS BEEN TRENDING TOWARD MORE AVAILABLE MOISTURE...AND A FASTER CHANGEOVER TO SNOW. IT IS POSSIBLE SNOW COULD BEGIN EVEN SOONER THAN EXPECTED IN THE NORTHWEST...OR SOMETIME TUESDAY AFTERNOON. ALSO...THERE ARE SOME INDICATIONS THAT A RUMBLE OF THUNDER OR TWO COULD ACCOMPANY THE SNOW...WHICH COULD LEAD TO LOCALLY HEAVIER AMOUNTS. TEMPERATURES IN MUCH OF THE NORTH WILL REMAIN ABOVE FREEZING DURING THE EVENT...AND ROADS WILL TEND TO BE MOSTLY WET. HOWEVER... WHERE SNOW IS HEAVIER IN THE NORTHWEST...ROADS COULD BECOME HAZARDOUS. IN THE CENTRAL THIRD OF THE STATE...THERE COULD BE SOME SNOWFLAKES TOWARD DAWN WEDNESDAY. HOWEVER...LITTLE OR NO ACCUMULATION IS EXPECTED. ALL PRECIPITATION WILL END WEDNESDAY MORNING...WITH TEMPERATURES CLIMBING INTO THE 40S DURING THE AFTERNOON. WHATEVER SNOW FALLS WILL MELT QUICKLY. THIS SITUATION WILL CONTINUE TO BE MONITORED CLOSELY BY THE NATIONAL WEATHER SERVICE. ARKANSANS SHOULD CHECK LATER FORECASTS... AND MAKE PLANS ACCORDINGLY. $$ 46 |

GFS 12z bombs out coastal low.1000 mb to 956 mb in 24hrs getting historical territory!!! The New York NWS discuss in a detailed way what to expect with the next two events. AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY 330 PM EST MON FEB 11 2013 .SYNOPSIS... A FRONTAL SYSTEM MOVES ACROSS THE AREA THIS EVENING. HIGH PRESSURE BRIEFLY BUILDS IN TUESDAY BEFORE A DEVELOPING LOW PRESSURE APPROACHES ON WEDNESDAY. LOW PRESSURE MOVES TO THE MID ATLANTIC COAST BY WEDNESDAY EVENING...THEN TRACKS TO THE SOUTH AND EAST OF LONG ISLAND WEDNESDAY NIGHT. WEAK HIGH PRESSURE TRANSITS ACROSS THE AREA THURSDAY AND THURSDAY NIGHT. THIS IS FOLLOWED BY AN AREA OF LOW PRESSURE MOVING ACROSS SOUTHEASTERN CANADA FROM FRIDAY INTO SATURDAY...THAT GIVES WAY TO A COASTAL LOW TRACKING TO THE SOUTH AND EAST OF LONG ISLAND SATURDAY NIGHT AND SUNDAY. HIGH PRESSURE THEN BUILDS IN TO THE REGION INTO EARLY NEXT WEEK. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... TWO FORECAST CHALLENGES IN THIS TIME FRAME/ FIRST THE COASTAL LOW TRACKING TO OUR S/E WEDNESDAY NIGHT...AND SECOND THE POTENTIAL FOR A COASTAL LOW THIS WEEKEND. GOOD AGREEMENT THAT A DEEP LAYERED RIDGE SLIDES TO OUR EAST BY WEDNESDAY AFTERNOON...ALLOWING FOR INCREASING ISENTROPIC LIFT AND LOW LEVEL ADVECTION TO DEVELOP BY LATE AFTERNOON MAINLY ACROSS THE SW 1/2 OF THE CWA. PRECIPITATION SHOULD BEGIN MAINLY AS RAIN WITH A RELATIVELY WARM BOUNDARY LAYER TO GET STARTED...HOWEVER WITH WET BULB TEMPERATURES IN THE LOWER 30S...EXPECT RAPID COOLING AS THE PRECIPITATION STARTS...AND WOULD EXPECT PRECIPITATION TO CHANGE TO ALL SNOW BY EVENING. 12Z ECMWF HAS TRENDED NORTHWARD WITH THE SURFACE LOW - MAINLY BECAUSE IT NOW HAS A MORE REASONABLE LOW PLACEMENT COMPARED TO ITS 500 AND 700 HPA FEATURES COMPARED TO THE 00Z ECMWF - WHICH HAD ITS SURFACE LOW TO FAR TO THE S/E COMPARED TO ITS UPPER AIR FEATURES. THE 12Z NAM IS A STRONG OUTLIER BY AROUND 50M WITH THE STRENGTH OF ITS 500 HPA TROUGH WEDNESDAY NIGHT...SO DO NOT BUY INTO ITS QPF. THE INTERESTING THING IS THAT ALOFT THE SOLUTIONS AMONG THE VARIOUS MODELS ARE NOT ALL THAT DIFFERENT...ITS AT THE SURFACE AND BOUNDARY LAYER WHERE THE DIFFERENCES LIE. NOTING THAT MOST SOLUTIONS SEEM TO BE TENDING TOWARDS ONE LIKE THE 12Z GFS...HAVE USED IT AS THE GENERAL BASIS FOR THE FORECAST FROM WEDNESDAY NIGHT INTO THURSDAY MORNING. HOWEVER...GIVEN THE KNOWN PROGRESSIVE BIAS TO THE MODEL...HAVE LINGERED CHANCE POPS INTO THURSDAY MORNING OVER FAR E ZONES. HAVE USED A BLEND OF NAX/MAX GUIDANCE WET BULB TEMPERATURES FOR THE LOW TEMPERATURE AND HOURLY TEMPERATURE GRIDS WEDNESDAY NIGHT - UNDER CUTTING THE FORECAST TEMPERATURES IN THE MAV/MET GUIDANCE BY A FEW DEGREES. AS A RESULT - WITH NO WARM LAYER FORECAST ALOFT...PRECIPITATION SHOULD FALL AS ALL SNOW WEDNESDAY NIGHT. FOR NOW FORECASTING A GENERAL 3-6 INCH SNOW FALL ACROSS THE TRI-STATE - WITH HIGHEST AMOUNTS ACROSS NYC METRO/LONG ISLAND/COASTAL CT. THIS IS SOLIDLY IN THE ADVISORY CATEGORY. CURRENTLY CONFIDENCE AT WARNING LEVEL SNOW FALL IS NOT AT 30% - SO WILL NOT BE MENTIONING THIS STORM IN THE HWO AT THIS TIME. RIDGING BUILDS BACK IN FOR THURSDAY...WITH DRY WEATHER OUTSIDE OF POSSIBLY SOME LIGHT SNOW TO GET STARTED OVER FAR EASTERN ZONES. MODELS ALL AGREE IN SW FLOW ALOFT SETTING UP FROM THURSDAY NIGHT INTO AT LEAST FRIDAY NIGHT...THEN DIVERGE FOR THE UPCOMING WEEKEND. APPEARS MOST SHORTWAVE ENERGY STAYS FAR ENOUGH TO THE N THURSDAY NIGHT TO KEEP THE AREA DRY...THEN IS CLOSE ENOUGH FRIDAY AND FRIDAY NIGHT TO WARRANT SLIGHT CHANCE POPS THEN. ECMWF AND TO SOME EXTENT THE GFS ENSEMBLE MEAN DO NOT SUPPORT THE IDEA OF A SIGNIFICANT COASTAL STORM IMPACTING THE AREA - WHILE THE GFS/CMC-GLOBAL/UKMET/ECMWF ENSEMBLE MEAN ARGUE FOR A COASTAL LOW. FOR NOW HAVE TRIED TO BLEND THE TWO CAMPS WITH NO CLEAR SIGNAL WHICH ONE OF THE TWO COULD BE ULTIMATELY MORE CORRECT. SO A VERY LOW CONFIDENCE FORECAST FOR THE UPCOMING WEEKEND. HAVE SLIGHT CHANCE POPS SATURDAY AS IT APPEARS THAT SOME SHORTWAVE ENERGY SHOULD CROSS THE REGION...THEN HAVE LOW END CHANCE POPS SATURDAY NIGHT AND SUNDAY AS THIS APPEARS TO BE THE MOST LIKELY TIME FRAME FOR ANY COASTAL LOW TO IMPACT THE AREA. GIVEN THE FORECAST TRACK TO THE S/E OF LONG ISLAND AND BOTH ECMWF AND GFS LOW LEVEL THERMAL PROFILES SUPPORT SNOW - CURRENTLY DO NOT EXPECT ANY P-TYPE ISSUES - ONLY SNOW AT THIS TIME. BECAUSE OF THE UNCERTAINTY IT IS TO EARLY TO SPECULATE ON EVEN WHETHER THERE WILL BE A SIGNIFICANT SNOWFALL ACROSS THE REGION THIS WEEKEND. DEEP LAYER RIDGING BUILDS IN MONDAY BEHIND THE DEPARTING UPPER TROUGH WHICH WOULD BE RESPONSIBLE FOR ANY WINTER STORM WE MIGHT HAVE THIS WEEKEND. FOR TEMPERATURES THURSDAY-MONDAY USED A BLEND OF MEX/MEN/ECE/HPC GUIDANCE...BLENDING IN NAM 2-METER TEMPERATURES AND A MIX DOWN FROM 950 HPA NEAR THE COAST AND 925 HPA INLAND FOR HIGHS ON THURSDAY. EXPECT NEAR NORMAL TEMPERATURES ON THURSDAY...THEN ABOVE NORMAL ON FRIDAY...FOLLOWED BY BELOW NORMAL TEMPERATURES SATURDAY AND SUNDAY. |

GFS 12z bombs out coastal low.1000 mb to 956 mb in 24hrs getting historical territory!!! GFS doesn't seem to be the most accurate of models... [link to www.facebook.com] @BAM_Chase on Twitter They actually just posted a graph of model accuracy comparisons on their FB page... [link to www.facebook.com] Not saying it's out of the realm of possibility by any means, but by a lot of the things I see on Twitter from the various weather sites I follow [most of which are pretty accurate, especially BAM_Chase... they were on top of Sandy before anyone else, and they're mostly a localized Indiana weather group]... general consensus is that GFS is hit and miss. The ECMWF model seems to have the highest accuracy for the most part. @Ryan_Maue, @BAM_Chase, @RightWeather [New England based], and a couple other Twitter deals are what I follow. Thanks for all your info... nice to see people actually give a shit about what goes on with the weather in advance of potential storms... instead of always dismissing them. "A person is smart. People are dumb, panicky dangerous animals and you know it. Fifteen hundred years ago everybody knew the Earth was the center of the universe. Five hundred years ago, everybody knew the Earth was flat, and fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow." |

Never seen one quite that deep, but it sounds very plausible to me. There was one back in 2007 (the week after I played at Carnegie actually) which dropped to 959 or so, and that storm was in mid April, so I don't see why not. I think they recorded a 950ish mb pressure about half a century ago in the northeast with a nor'easter, so it's in the realm of possibility. [link to www.wunderground.com] |
Anonymous Coward User ID: 34174091 Portugal 02/11/2013 05:01 PM Report Abusive Post Report Copyright Violation | Re: 932 mb Extratropical Monster Storm to Northeast !!! GFS 12z bombs out coastal low.1000 mb to 956 mb in 24hrs getting historical territory!!! Here's What We Know About The Pressure Records From October 26, 2010 The low pressure rapidly deepened on October 26, 2010, leading to several pressure records being broken. Here are some facts about those pressure records: •Bigfork, MN (KFOZ) had a minimum sea level pressure of 955.2 millibars (28.21") at 5:13 pm CDT This is recalculated slightly from the lowest altimeter reading of 28.20" that was initially reported for this storm. Both altimeter readings and sea level pressure are derived from the station pressure. Although the altimeter reading is a sea level reduction as well, it uses a US standard atmosphere assumption. The sea level pressure factors in observed temperatures. Therefore, the altimeter and sea level pressure readings are often very slightly different. •955.2 millibars is now the Minnesota state record for lowest observed sea level pressure The previous record was 962.7 millibars (28.43"), set on November 10, 1998 at both Albert Lea, MN and Austin, MN. •Superior, WI had a minimum sea level pressure of 961.3 millibars (28.39") at 11:15 am CDT This is now the Wisconsin state record for lowest observed sea level pressure The previous record was 963.4 millibars (28.45"), set on April 3, 1982 at Green Bay, WI. •Our two climate reporting sites set low pressure records as well Duluth, MN had a minimum sea level pressure of 960.2 millibars (28.35") at 11:15 am CDT. This broke the old record at Duluth which was 964.3 millibars (28.48"), set on November 10, 1998. International Falls, MN had a minimum sea level pressure of 956.0 millibars (28.23") at 3:45 pm CDT. This broke the old record which was 971.9 millibars (28.70"), set on October 10, 1949. Was This Any Kind Of National Record For Lowest Pressure? The bottom line, is that Bigfork, Minnesota did not set the CONUS record for lowest extratropical sea level pressure. Here are the details: •The lowest sea level pressure recorded at any United States certified observing station was 892 millibars (26.34"), recorded at Matecumbe Key, Florida on September 2, 1935 in the "Labor Day Hurricane". Therefore, the reading at Bigfork on October 26th was not the lowest pressure in the entire United States. •The lowest sea level pressure recorded in a non-tropical (extratropical) storm at any United States certified observing station was 927 millibars (27.35"), recorded at Dutch Harbor, Alaska on October 25, 1977. Therefore, the reading at Bigfork on October 26th was also not the lowest pressure in the entire United States for a non-tropical storm. •Many storms have been discussed as potential record holders for the lowest recorded sea level pressure in a non-tropical storm at a land-based observing station in the Continental United States (CONUS). The lowest that has been mentioned was 951.6 millibars at Bridgehampton, NY on March 3, 1914. However, this value cannot be confirmed by records held at the National Climatic Data Center (NCDC). •The lowest CONUS, land-based, non-tropical, sea level pressure that can be confirmed by NCDC is 955.0 millibars (28.20"). This occurred twice in United States history. The first time was on January 3, 1913 at Canton, NY. The second was on March 7, 1932 at Block Island, Rhode Island. These were verified by NCDC using archived climate data publications. ... [link to www.crh.noaa.gov] |
