URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 556 NWS Storm Prediction Center Norman OK 535 PM CDT Fri Jul 19 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Colorado Southwest Kansas Far Northwest Oklahoma and the Oklahoma Panhandle The Texas Panhandle * Effective this Friday afternoon from 535 PM until Midnight CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Isolated very large hail events to 2 inches in diameter possible SUMMARY...Thunderstorms should generally move southward this evening while posing a threat for scattered damaging winds around 60-70 mph, with isolated stronger gusts possible.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Fri Jul 19 2024

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

Central and Western East Pacific:
A tropical wave located along a monsoon trough well to the south of
the coast of Mexico is producing a broad area of showers and
thunderstorms. Some gradual development of this system is possible
over the next several days as it moves westward to
west-northwestward at 10 to 15 mph, moving into the western portion
of the basin by the middle to latter parts of next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

MD 1684 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHWEST SOUTH DAKOTA AND WEST-CENTRAL NEBRASKA
Mesoscale Discussion 1684 NWS Storm Prediction Center Norman OK 0450 PM CDT Fri Jul 19 2024 Areas affected...southwest South Dakota and west-central Nebraska Concerning...Severe potential...Watch possible Valid 192150Z - 192345Z Probability of Watch Issuance...40 percent SUMMARY...Thunderstorms should gradually increase in coverage and intensity this afternoon/evening. A risk for hail and damaging gusts may evolve. A WW is possible. DISCUSSION...As of 2140 UTC, regional radar and satellite imagery showed isolated thunderstorms developing near a frontal zone across southern SD, northern NE and eastern WY. Warming afternoon surface temperatures in the 80s to 90s F with 50s and 60s F dewpoints are supporting moderate buoyancy of 1500-2500 J/kg across southern SD and western NE. Enhanced mid-level flow ahead of a weak perturbation was observed on area VADs, with effective shear of 35-45 kt. Isolated organized storms, including supercells, appear possible given the favorable CAPE/shear overlap. While mid-level lapse rates are not overly steep (7-7.5 C/km), the moderate buoyancy and potential for updraft rotation suggest a risk for hail with the stronger storms. Damaging gusts are also possible with LCL heights above 2,000 m. Additional storm development/intensification will remain possible late this afternoon and into the evening as weak ascent continues to overspread the central High Plains. Exact storm coverage remains uncertain given the relatively narrow zone of buoyancy and cloud debris from earlier convection. Still, some CAM guidance suggests a cluster or storms may eventually evolve with the potential for hail and damaging winds across parts of southwest SD and west-central NE. While convective evolution and the degree of severe risk remains unclear, conditions will be monitored for a possible WW. ..Lyons/Gleason.. 07/19/2024 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 557 NWS Storm Prediction Center Norman OK 500 PM MDT Fri Jul 19 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far Northeast Colorado Western and Central Nebraska Southwest South Dakota * Effective this Friday afternoon and evening from 500 PM until 1100 PM MDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Ongoing supercells should continue to pose a threat for large hail up to 1-2 inches in diameter as they move generally southward this evening. Some threat for damaging winds around 60-75 mph may also exist, especially if a thunderstorm cluster can develop later this evening. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 5 miles east northeast of Rapid City SD to 35 miles west southwest of North Platte NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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.

MD 1683 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR CENTRAL/SOUTHERN HIGH PLAINS
Mesoscale Discussion 1683 NWS Storm Prediction Center Norman OK 0441 PM CDT Fri Jul 19 2024 Areas affected...Central/Southern High Plains Concerning...Severe potential...Watch likely Valid 192141Z - 192245Z Probability of Watch Issuance...80 percent SUMMARY...New Severe Thunderstorm Watch appears warranted for portions of the central/southern High Plains. DISCUSSION...Weak short-wave trough is evident within water-vapor imagery digging south-southeast across the central Plains. Scattered convection now reflects the leading edge of this feature, with thunderstorms gradually increasing across the central portions of ww555 from northwestern KS into eastern CO. This activity should propagate south along the primary corridor of instability (MLCAPE on the order of 2000 J/kg) toward the OK Panhandle later this evening. While LLJ is not forecast to be that strong, 25kt southerly jet should aid in the longevity of this activity as it spreads south across the High Plains. Damaging winds are the main risk, though some hail is possible. ..Darrow/Gleason.. 07/19/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OUN...DDC...GLD...AMA...PUB...
