Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Mon Jul 29 2024

For the eastern North Pacific...east of 140 degrees west longitude:

South of Southern Mexico (EP94):
Satellite images indicate that an area of low pressure located a
few hundred miles south of the southern coast of Mexico continues
to show signs of organization. Environmental conditions appear
conducive for further development of this system, and a tropical
depression is very likely to form within the next couple of days.
The system is forecast to move westward to west-northwestward at 10
to 15 mph during the next several days, remaining offshore of the
southern coast of Mexico.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

Western East Pacific:
A tropical wave located well to the southwest of the southern tip of
the Baja California Peninsula continues to produce disorganized
showers and thunderstorms. Gradual development of this system is
possible during the middle and latter parts of the week while it
moves westward to west-northwestward at about 10 mph across the
western portion of the basin.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...30 percent.

South of Central America and Southern Mexico:
An area of low pressure is forecast to form offshore of the coast of
Central America and southern Mexico later this week. Environmental
conditions appear conducive for gradual development of this system,
and a tropical depression is likely to form towards the end of the
week or this weekend. The system is forecast to move westward to
west-northwestward at 10 to 15 mph during the next several days,
remaining offshore.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...high...70 percent.

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 561 NWS Storm Prediction Center Norman OK 425 PM CDT Mon Jul 29 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central North Dakota Northern Nebraska Central South Dakota * Effective this Monday afternoon from 425 PM until Midnight CDT. * Primary threats include...

MD 1733 CONCERNING SEVERE THUNDERSTORM WATCH 563... FOR PARTS OF SOUTHERN ILLINOIS...ADJACENT PORTIONS OF INDIANA AND KENTUCKY
Mesoscale Discussion 1733 NWS Storm Prediction Center Norman OK 0927 PM CDT Mon Jul 29 2024 Areas affected...parts of southern Illinois...adjacent portions of Indiana and Kentucky Concerning...Severe Thunderstorm Watch 563... Valid 300227Z - 300430Z The severe weather threat for Severe Thunderstorm Watch 563 continues. SUMMARY...Ongoing thunderstorms may gradually evolve into organizing southeastward propagating cluster with increasing risk for potentially damaging wind gusts through 11 PM-Midnight CDT. DISCUSSION...Storms initiating to the northeast through east of the Greater St. Louis area, have been supported by forcing for ascent associated with low-level warm advection, in the wake of mid-level troughing slowly digging through the upper Great Lakes/Ohio Valley. This has been occurring within a very moist (including upper 70s surface dew points) and highly buoyant boundary layer, in the presence of at least modest clockwise curved hodographs, beneath 30-40+ kt northwesterly flow in the 700-500 mb layer. While a few supercell structures have evolved, with gradual decoupling of the boundary layer underway and flow closer to the surface (near and below 850 mb) forecast to remain more modest, tornadic potential seems likely to remain limited. However, with some further upscale growth still probable through 04-05Z, increasing outflow, aided by evaporative cooling within dry/potentially cool air in the lower/mid-troposphere and melting hail, may be accompanied by increasing potential for damaging surface gusts. ..Kerr.. 07/30/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1734 CONCERNING SEVERE THUNDERSTORM WATCH 561... FOR PARTS OF SOUTHEASTERN NORTH DAKOTA AND NORTHEASTERN SOUTH DAKOTA
Mesoscale Discussion 1734 NWS Storm Prediction Center Norman OK 0933 PM CDT Mon Jul 29 2024 Areas affected...Parts of southeastern North Dakota and northeastern South Dakota Concerning...Severe Thunderstorm Watch 561... Valid 300233Z - 300400Z The severe weather threat for Severe Thunderstorm Watch 561 continues. SUMMARY...The severe threat continues across portions of southern/southeastern North Dakota and northern/northeastern South Dakota in Severe Thunderstorm Watch 561. The severe threat may spread eastward out of the watch, and a new watch or watch extension may be needed. DISCUSSION...An increasingly organized north/south-oriented MCS is tracking eastward across south-central ND and north-central SD at around 30-40 kt, while an additional cluster of storms to its east is drifting slowly northward within a warm-advection wing. The MCS is gradually merging/overtaking the eastern cluster. Ahead of these storms, 2500-3000 J/kg MLCAPE (sampled by the ABR 00Z sounding) will likely support the maintenance of this activity as it continues eastward. Additionally, the ABR 00Z sounding and recent KBIS VWP data indicate a long/straight hodograph -- characterized by around 40 kt of westerly deep-layer shear. The combination of the favorable instability and shear vectors oriented perpendicular to the leading-edge gust front, should favor a continued organized/linear mode. Severe wind gusts to around 75 mph will be the primary concern. A downstream watch or watch extension may be needed. ..Weinman.. 07/30/2024 ...Please see www.spc.noaa.gov for graphic product...
