October 17, 1781 
General Cornwallis attempted to escape encirclement by crossing York River, "but a violent storm arose" dispersing his boats causing him to ask for an armistice. (Sandra and TI Richard Sanders - 1987) 

October 17, 1910 
A hurricane made a loop off the southwest coast of Florida. Winds above 100 mph were reported at Fort Myers FL, and the barometric pressure at Sand Key reached 28.40 inches. (David Ludlum) 

October 17, 1950 
Small but powerful Hurricane King struck Miami, FL. The hurricane packs winded to 122 mph, with gusts to 150 mph. Hurricane King then moved up the Florida peninsula to Georgia. Four persons were killed and damage was 28 million dollars. (David Ludlum) (The Weather Channel) 

October 17, 1971 
Great balls of fire were observed just ahead of a tornado moving down the main street of Wray CO. However, little other electrical activity accompanied the storm. Nine persons were injured in the tornado, all at a trailer court at the edge of town. (The Weather Channel) 

October 17, 1984 
A snowstorm struck northern Utah producing a record 18 inches in 24 hours at Salt Lake City, and 40 inches at the nearby Alta Ski Resort. The town of Magna, located ten miles west of Salt Lake City, did not receive any snow at all. The storm was responsible for a fifty vehicle pile-up along Interstate 15 near Farmington UT. (Storm Data) 

October 17, 1987 
It was a great day for an Oktoberfest, or to enjoy the colors of autumn, as much of the nation enjoyed sunny and mild weather. Columbia SC dipped to 34 degrees, marking their third morning in a row of record cold. Bakersfield CA reached 80 degrees for the 143rd day in a row to break a record established in 1940. (The National Weather Summary) 

October 17, 1988 
Thunderstorms produced severe weather in the Middle Mississippi Valley and the Lower Ohio Valley. Severe thunderstorms spawned three tornadoes in Indiana, including one which injured four persons. Strong thunderstorm winds at Connerville IND caused three million dollars damage. Thunderstorms in Illinois produced hail two inches in diameter Colfax. (The National Weather Summary) (Storm Data) 

October 17, 1989 
Showers and thunderstorms representing the remnants of Hurricane Jerry deluged southeast Kentucky with four to six inches of rain in 18 to 24 hours, resulting in widespread flash flooding. Flooding resulted in more than five million dollars damage. Temperatures again warmed into the 80s and lower 90s in the southeastern U.S. Lakeland FL and Orlando FL reported record highs of 95 degrees. (The National Weather Summary) (Storm Data)

    • 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...
