A second great windstorm in three days struck Vermont and New York blowing railroad trains off their tracks. (David Ludlum) 

November 20, 1900 
An unusual tornado outbreak in the Lower Mississippi Valley resulted in 73 deaths and extensive damage across Arkansas, Mississippi and Tennessee. (David Ludlum) 

November 20, 1914 
The high temperature of 28 degrees at Atlanta, GA, was their earliest daily high below the freezing mark. (The Weather Channel) 

November 20, 1979 
A blizzard struck Cheyenne, WY, producing a record 19.8 inches of snow in 24 hours, and a record total of 25.6 inches in forty hours. Strong winds created huge drifts stopping all transportation. (19th-21st) (The Weather Channel) 

November 20, 1981
An F-1 tornado moved across the Atlanta International Airport and the southern portion of Hapeville (Fulton County). The tornado lifted a skyroof off of Concourse B and damaged windshields on several jetliners parked at the gates. Near the Cargo Building a DC8 had an engine torn off as it taxied to a stop and 3 small planes were picked up and flipped over. Five airline employees were injured. In Hapeville, the tornado tore part of the roof from an apartment building. (NWS Atlanta)


November 20, 1987 
Blustery northwest winds created snow squalls in the Great Lakes Region and the Upper Ohio Valley. Snowfall totals in Upper Michigan ranged up to 18 inches at Paradise. Lake City MI received 9.5 inches of snow in four and a half hours. Up to a foot of snow blanketed Oswego County in western New York State. Strong winds produced wind chill readings as cold as 22 degrees below zero at Duluth MN. (The National Weather Summary) (Storm Data) 

November 20, 1988 
Thunderstorms developing ahead of a fast moving cold front produced severe weather in the Upper Ohio Valley and the Middle Atlantic Coast Region during the afternoon and early evening. Thunderstorm winds gusted to 69 mph at Kennedy Airport in New York City, and winds along the cold front itself gusted to 56 mph at Cincinnati OH. The same storm produced snow in Kansas, Missouri and Illinois, with eight inches reported at Rolla MO. (The National Weather Summary) (Storm Data) 

November 20, 1989 
Low pressure brought thunderstorms and high winds to the northeastern U.S. There were 193 reports of damaging winds with thunderstorms in New York State, Pennsylvania and New Jersey. Tornadoes touched down near Seaside Park NJ and McAlevys Port PA. Winds with thunderstorms gusted to 92 mph at Poughkeepsie NY, and reached 94 mph at Newburgh NY. High winds in the Washington D.C. area, gusting to 73 mph, resulted in one death. (Storm Data) (The National Weather Summary)

    • MD 1767 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL AND NORTHERN ILLINOIS AND WESTERN INDIANA Mesoscale Discussion 1767 NWS Storm Prediction Center Norman OK 0800 AM CDT Sat Aug 17 2019 Areas affected...central and northern Illinois and western Indiana Concerning...Severe potential...Watch unlikely Valid 171300Z - 171500Z Probability of Watch Issuance...20 percent SUMMARY...Thunderstorms will continue to move out of Missouri and into central Illinois this morning. Additional thunderstorms will be possible across northern Illinois as well. Hail and gusty winds may be possible with the strongest cores. The area will be monitored for potential watch, but current indications are that the threat should remain sufficiently isolated to not warrant one. DISCUSSION...Long-lived cluster of thunderstorms continues to move east from northern Missouri into central Iowa. Most-unstable CAPE along and ahead of this cluster is around 1000-1500 J/kg; however, deep-layer shear is generally less than 25 knots. Thus, although a severe hail or strong thunderstorm wind gust will be possible with the strongest cores, the threat should remain sufficiently isolated/episodic that a watch is not currently anticipated for this activity. To the north, across northern Illinois, additional thunderstorms may develop within a belt of stronger midlevel flow, likely in response to ageostrophic forcing from the mesoscale convective system to the southwest. The result will be thunderstorms developing in an objectively analyzed environment of most-unstable CAPE around 1000-1500 J/kg and deep-layer shear of 40-50 knots. Although this would normally suggest a threat for organized severe thunderstorms, considerable uncertainty remains regarding convective coverage and longevity. As such, area will continue to be monitored for potential watch, but expectations are that the threat will remain too isolated in nature to warrant watch issuance. ..Marsh/Edwards.. 08/17/2019 ...Please see www.spc.noaa.gov for graphic product...

    • Saturday, August 17 2019 Preference: Blend of the 00Z GFS/ECMWF, and GEFS/ECENS means Confidence: Average The large scale flow across the CONUS will remain broadly cyclonic through the weekend, although gradual height rises are expected by later Sunday and early next week across the central and southern U.S. Shortwaves rotating through the flow will be the primary sensible weather makers, and it is discrepancy among these features that lead to the preferred blend. The most notable differences involve the 00Z NAM which continues to be a relatively strong outlier with several of these vort lobes impacting the Plains/Midwest that are shedding around a complex of upper lows in Canada. In fact, the NAM gradually becomes out of tolerance with the global model consensus across much of central/southern Canada by the end of the period. The 00Z UKMET also is problematic with energy it has lifting up across the upper Midwest through early Sunday as it is sharper and stronger with a surface wave lifting up along a cold front crossing this region. The UKMET also is out of tolerance across Canada versus the model consensus, which is strongly supported at this point by the 00Z GFS and 00Z ECMWF overall. Across the Southeast and Mid-Atlantic coastal plain, a persistent and quasi-stationary frontal zone is expected to be the focus for multiple waves of low pressure. One wave of low pressure will eject northeast off the Mid-Atlantic coast and out to sea on Saturday. Meanwhile, a second wave of low pressure situated already down across northern FL will lift northeast very close to the Southeast and southern-Mid-Atlantic coastline through Sunday before then exiting offshore and out to sea on Monday. The 00Z NAM, 00Z CMC and especially the 00Z UKMET intensify this low center as it lifts northeast up the coast, with the 00Z GFS and 00Z ECMWF showing more modest development. A large number of Canadian ensemble members and a fair number of the GEFS members favor at least a modest low center, with the vast majority of the ECENS members more ill-defined. The 00Z NAM-conest, 00Z ARW/ARW2 solutions show a bit more development comparable to the NAM, but the 00Z NMMB is a weak outlier. There is strong support toward a GFS/ECMWF blend out of the latest GEFS/ECENS means across the CONUS, and thus a blend of all of these will be preferred at this point. However, a slightly stronger version of the GFS/ECMWF solutions is suggested along the Southeast and Mid-Atlantic coasts with the low center lifting northeast across these areas on Sunday.
