November 27, 1883 
Fire engines were called out in New York City and New Haven, CT, as a result of the afterglow of the sunset due to vivid red ash from the Krakatoa Volcano explosion in August. (The Weather Channel) 

November 27, 1898 
The Portland storm raged across New England producing gale force winds along the coast and heavy snow inland. A foot of snow blanketed Boston MA, and 27 inches fell at New London CT. Winds at Boston gusted to 72 mph, and wind gusts to 98 mph were estimated at Block Island RI. A passenger ship, the S. S. Portland, sank off Cape Cod with the loss of all 191 persons aboard, and Boston Harbor was filled with wrecked ships. The storm wrecked 56 vessels resulting in a total of 456 casualties. (26th- 28th) (David Ludlum) (The Weather Channel) 

November 27, 1987 
Wet weather prevailed across much of the nation east of the Rockies. Sunny and cool weather prevailed in the western U.S. Snow fell in the central U.S., with totals in Kansas ranging up to six inches at Burr Oak. Much of the area from central Oklahoma to southwestern Minnesota experienced its first snow of the winter season. (The National Weather Summary) 

November 27, 1988 
Snow and high winds created blizzard conditions in Minnesota. Winds gusted to 63 mph at Windom, and snowfall totals ranged up to 14 inches at Aitkin. Snow drifts seven feet high closed many roads. Fargo ND reported a wind chill reading of 34 degrees below zero. (The National Weather Summary) (Storm Data) 

November 27, 1989 
A storm system crossing the north central U.S. spread snow across the Dakotas and Minnesota. Heavy snow fell in western South Dakota, with 18 inches reported at Galena. Strong winds associated with the storm gusted to 50 mph in the Great Lakes Region and the Great Plains, with blowing dust reported in Kansas. Thunderstorms associated with the same storm system produced damaging winds in Michigan, Ohio and Indiana during the evening, with gusts to 73 mph reported east of Ypsilante MI. Unseasonably warm weather prevailed ahead of the cold front. Twenty-three cities from the Gulf coast to the Ohio Valley and the Mid Mississippi Valley reported record high temperatures for the date, including Saint Louis MO with a reading of 76 degrees. (The National Weather Summary) (Storm Data) 

November 27, 2005 
A major winter storm affected parts of Nebraska and the Dakotas during the 27th-28th. Snowfall accumulations of 16-20 inches were observed in parts of eastern South Dakota, while wind gusts exceeding 60 mph also accompanied the snow, creating blizzard conditions. Thousands of power outages were caused by the combination of strong winds and heavy snow. In South Dakota, about 8,000 utility poles and 10,000 miles of transmission line were brought down by the storm (Associated Press).

    • MD 0696 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR EASTERN NM AND PORTIONS OF THE OK/TX PANHANDLES INTO WESTERN TX Mesoscale Discussion 0696 NWS Storm Prediction Center Norman OK 1156 PM CDT Sun May 19 2019 Areas affected...eastern NM and portions of the OK/TX Panhandles into western TX Concerning...Severe potential...Watch likely Valid 200456Z - 200700Z Probability of Watch Issuance...80 percent SUMMARY...Thunderstorms are expected to develop by 1-3 am CDT. Large hail will be the main concern with activity through early morning. A watch will likely be needed in the next couple of hours. DISCUSSION...Strong southeasterly flow through around 1 km continues to bring rich Gulf moisture northwest across TX into eastern NM late this evening. Dewpoints have increased 8 to 16 degrees in the last 3 hours from the Davis Mountain region in western TX into southeastern NM as evidence of this strong moisture surge. Regional 00z RAOBs from CRP and DRT showed surface dewpoints of 80 and 69 F respectively. As such, deeper boundary layer moisture is expected to overspread much of western TX and into far eastern NM overnight. A resulting surge in instability will accompany the moisture return and MLCAPE values around 500 J/kg were already shifting northwest into southeast NM. As this trend continues the next few hours, modest forcing along a surface dryline and subtle impulses ejecting from eastward progressing upper trough over the western Great Basin should trigger convective initiation in the 06-08z time frame. Water vapor and IR satellite imagery indicate a subtle wave is spreading northeast across southern AZ and northern Mexico as of 0430z with increasing cloud cover and cooling cloud temps noted in addition to more agitated cloud features over southeast NM into far west TX. This initial activity will likely be elevated given the cool boundary layer. However, impressive effective shear of 60+ kt with large, curved hodographs will support rotating/supercell structures. Hail will be the main concern with this activity overnight, though a 40-50 kt south/southwesterly low level jet could result in upscale growth into a squall line or bowing segments. Given surface inhibition, the wind and tornado threat should remain limited until after sunrise. A watch will likely be needed for portions of the MCD area by around 06-07z. ..Leitman/Guyer.. 05/20/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LUB...AMA...MAF...ABQ...

    • MD 0695 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHWEST MS...SOUTHEAST AR...NORTHERN LA AND EXTREME NORTHEAST TX Mesoscale Discussion 0695 NWS Storm Prediction Center Norman OK 0721 PM CDT Sun May 19 2019 Areas affected...portions of northwest MS...southeast AR...northern LA and extreme northeast TX Concerning...Severe potential...Watch unlikely Valid 200021Z - 200145Z Probability of Watch Issuance...20 percent SUMMARY...Locally damaging wind gusts and small hail are possible with strongest storms the next 2-3 hours. Overall threat should remain very isolated and a watch is not expected. DISCUSSION...Widely scattered but robust thunderstorms development was occurring along the surface cold front located across southeast AR toward the ArkLaTex vicinity. Ahead of the cold front, a very warm and moist airmass with temperatures in the 80s and dewpoints in the low 70s was resulting in strong instability and steep low level lapse rates within an area of modest effective shear. Midlevel lapse rates are rather poor across the region and this should hinder longevity of intense organized updrafts. Given weak low level shear combined with high PWs and steep 0-3 km lapse rates, strong to locally damaging wind gusts are possible the next couple of hours. Some small hail may also be possible with strongest cells. Overall, the threat should remain limited in time, space and scope, and is expected to diminish quickly this evening with loss of daytime heating and a stabilizing boundary layer. As such, a watch is not expected. ..Leitman/Guyer.. 05/20/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MEG...JAN...LZK...SHV...

    • MD 0693 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF EASTERN PA...NJ...SOUTHERN NY AND WESTERN MA/CT Mesoscale Discussion 0693 NWS Storm Prediction Center Norman OK 0555 PM CDT Sun May 19 2019 Areas affected...portions of eastern PA...NJ...southern NY and western MA/CT Concerning...Severe potential...Watch possible Valid 192255Z - 200030Z Probability of Watch Issuance...60 percent SUMMARY...A new watch may be needed downstream of WW 192 and 193. Locally damaging wind and hail threat could persist for several more hours eastward toward the I-95 corridor and southern NY. DISCUSSION...Scattered severe thunderstorms continue to track northeast across central and eastern PA and eastern NY. Storms have remained semi-discrete with a tenancy toward upscale growth into bowing structures. Convection may persist beyond the 01z expiration time of WW 192 and 193 across parts of far western PA into southern NY and NJ where a very moist airmass (surface dew points in the upper 60s to low 70s) beneath steep midlevel lapse rates. As a result, a corridor of 1000-2000 J/kg MLCAPE resides from southeast PA into southern NY. Effective shear around 30 kt should remain adequate to support semi-organized structures into this evening and a locally damaging wind and hail threat could spread eastward toward the I-95 corridor/southern NY through around 04-05z. As such, a new watch may be needed. Instability quickly diminishes with eastward extent into western MA/CT and parts of Long Island where cloud cover has limited heating and dewpoints to the east of a quasi-stationary/warm frontal boundary are only in the 50s F. This should result in a a quickly diminishing severe threat east of the Hudson Valley. ..Leitman/Guyer.. 05/19/2019 ...Please see www.spc.noaa.gov for graphic product...

    • MD 0694 CONCERNING SEVERE THUNDERSTORM WATCH 194... FOR SOUTHEAST MICHIGAN...CENTRAL/NORTHERN INDIANA Mesoscale Discussion 0694 NWS Storm Prediction Center Norman OK 0600 PM CDT Sun May 19 2019 Areas affected...Southeast Michigan...Central/northern Indiana Concerning...Severe Thunderstorm Watch 194... Valid 192300Z - 200100Z The severe weather threat for Severe Thunderstorm Watch 194 continues. SUMMARY...The threat for damaging wind gusts and marginally severe hail will continue in WW 194 for another couple of hours. A brief tornado cannot be ruled out with the stronger, discrete storms. A downstream watch is not expected given the stable airmass ahead of the ongoing activity. DISCUSSION...Ongoing convection from southern Michigan to south of Indianapolis has been producing wind damage reports over the last two hours. Wind gusts have generally been higher in Indiana where instability is slightly greater. Measured wind gusts over the last hour or two have generally ranged from 45 to near 60 mph. A few clusters of storms have organized into small bowing segments in both Michigan and Indiana. The threat for damaging winds will be relative maximized ahead of that activity. A few storms have remained more discrete in northern Indiana into southern Michigan. A few of these storms have shown signs of transient low-level rotation with on storm having possibly produced a brief tornado in Barry County, MI per KGRR dual-pol data. Both KGRR and KIWX VAD profiles do show relatively large low-level shear; however, given the very modest instability as well as most of the deep-layer shear being concentrated in the lowest few kilometers, the overall tornado threat should be limited. With the downstream environment having very limited instability, the need for a downstream watch is unlikely. ..Wendt.. 05/19/2019 ...Please see www.spc.noaa.gov for graphic product...
