1135 PM EDT Wed Sep 1 2021
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Southeast Massachusetts
Rhode Island
Coastal Waters
* Effective this Wednesday night and Thursday morning from 1135
PM until 700 AM EDT.
* Primary threats include...
A couple tornadoes possible
Isolated damaging wind gusts to 70 mph possible
SUMMARY...A northward-advancing warm front near the coast in
addition to a moist air mass and strong low-level wind field will
support the possibility of a near-coastal/inland potential for
supercells with a brief tornado risk aside from convectively
enhanced winds.
The tornado watch area is approximately along and 40 statute miles
north and south of a line from 20 miles northwest of Block Island RI
to 25 miles east of Hyannis MA. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU6).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 484...WW 485...
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 0 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean
storm motion vector 23030.

URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 485
NWS Storm Prediction Center Norman OK
525 PM MDT Wed Sep 1 2021
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Western Nebraska
Southwest and Central South Dakota
* Effective this Wednesday afternoon from 525 PM until Midnight
MDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph possible
Scattered large hail events to 1.5 inches in diameter possible
A tornado or two possible
SUMMARY...Thunderstorms are expected to increase in coverage and
intensity this evening from the Nebraska Panhandle/northwest
Nebraska northeastward into southwest/central South Dakota.
Instances of large hail and damaging winds will be possible.
The severe thunderstorm watch area is approximately along and 65
statute miles east and west of a line from 30 miles south southwest
of Alliance NE to 55 miles east northeast of Philip SD. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

MD 1679 CONCERNING TORNADO WATCH 484... FOR FAR NORTHERN NEW JERSEY...SOUTHERN NEW YORK...LONG ISLAND...AND FAR SOUTHERN NEW ENGLAND
Mesoscale Discussion 1679
NWS Storm Prediction Center Norman OK
1020 PM CDT Wed Sep 01 2021
Areas affected...far northern New Jersey...southern New York...Long
Island...and far southern New England
Concerning...Tornado Watch 484...
Valid 020320Z - 020445Z
The severe weather threat for Tornado Watch 484 continues.
SUMMARY...Thunderstorms currently moving across Long Island and
southern New England will continue to pose a risk of strong
thunderstorm winds and a couple of tornadoes. A new watch downstream
of Tornado Watch #484 will be issued.
DISCUSSION...The remnant low-level circulation of post-tropical
cyclone Ida continues to move northeast toward the greater New York
City area. The low-level wind field continues to advect a very warm,
moist air northward into southern New England as a warm front slowly
lifts north across Long Island. Time-evolution VAD winds from Upton,
NY, (KOKX) suggests that the warm front is very near or just north
of the radar. Additionally, the time evolution of KOKX's VAD winds
indicates a strengthening wind field that veers with height, leading
to 0-1 kilometer SRH in excess of 800 m2/s2.
As thunderstorms continue to move east from northern New
Jersey/southern New York, across Long Island and southern New
England, they will interact with this extremely favorable kinematic
environment. The result is a continued potential for a couple of
tornadoes and strong thunderstorm winds along and south of the warm
front. The most appreciable tornado risk will be in the vicinity of
this lifting warm front, but how far north it lifts before being
overtaken by the approaching thunderstorms is uncertain. Portions o
coastal and near-coastal areas downstream from Tornado Watch #484
across southern New England will need a new tornado watch.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0759 PM CDT Wed Sep 01 2021
Valid 020100Z - 021200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE MID
ATLANTIC INTO SOUTHERN NEW ENGLAND...AND FROM WESTERN NE INTO SD...
...SUMMARY...
The threat for a few tornadoes and isolated damaging winds will
continue across the northern Mid Atlantic into far southern New
England through the remainder of tonight. A few severe storms are
also possible across portions of western Nebraska into South Dakota,
posing a threat of hail and damaging winds.
...Mid Atlantic/Southern New England...
Widespread convection is ongoing across northern portions of the Mid
Atlantic into southern New England this evening. Earlier tornadic
supercells have weakened, but wind profiles (as noted on KDIX VWP
and regional 00Z soundings) remain favorable for rotating storms,
with a few tornadoes and damaging winds possible into late tonight
with the strongest cells. The threat may spread into immediate
coastal areas of southern New England overnight, as the warm front
moves slowly northward in advance of the surface low associated with
post-tropical cyclone Ida.
...NE/SD...
Storm coverage is expected to increase this evening from western NE
into SD, as a mid/upper-level trough currently centered near the
Four Corners region moves northeastward. While convection may become
somewhat elevated with time, MUCAPE in excess of 1500 J/kg combined
with effective shear of 30-40 kt will support occasionally organized
storm structures, posing a threat of large hail and locally damaging
wind gusts.
