MD 1714 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHWESTERN MINNESOTA AND ADJACENT PORTIONS OF NORTH DAKOTA
Mesoscale Discussion 1714 NWS Storm Prediction Center Norman OK 0606 PM CDT Fri Jul 26 2024 Areas affected...northwestern Minnesota and adjacent portions of North Dakota Concerning...Severe potential...Watch unlikely Valid 262306Z - 270100Z Probability of Watch Issuance...20 percent SUMMARY...One or two supercells may evolve through the 7-9 PM CDT time frame, accompanied by potential for large hail and some risk for a brief tornado. This is not anticipated to require a severe weather watch, but trends are being monitored. DISCUSSION...Beneath a plume of very warm elevated mixed-layer air, a seasonably moist boundary-layer across parts of the Red River Valley has become characterized by CAPE on the order of 2000-3000 J/kg. This is generally focused within narrow corridors near the Red River, and immediately ahead of a weak eastward advancing cold front. Although lingering mid-level inhibition has slowed convective development, the initiation of sustained isolated to widely scattered thunderstorm development appears underway. Subtle mid-level cooling near the southern periphery of a mid-level cyclone crossing the Canadian Prairies may gradually erode inhibition further into early evening. However, based on the various model output, it remains unclear whether this will become supportive of a substantive increase in convective coverage. Even so, given at least a narrow window for continuing inflow of moderately unstable air, ongoing activity probably will continue to intensify. One or two supercells may eventually evolve in the presence of 35-50 kt southwesterly mid-level flow. Low-level hodographs appear modest, but a brief tornado may not be out of the question, in addition to a risk for large hail. ..Kerr/Hart.. 07/26/2024 ...Please see www.spc.noaa.gov for graphic product...

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Fri Jul 26 2024

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

Active Systems:
The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Bud, located well west-southwest of the
southern tip of the Baja California Peninsula.

South of Southern Mexico:
An area of low pressure could form by the middle of next week a few
hundred miles south of the coast of southern Mexico. Environmental
conditions appear conducive for some gradual development thereafter
while the system moves west-northwestward at 10 to 15 mph, roughly
parallel to the coast of southwestern Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

MD 1713 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL AND SOUTHERN ARIZONA
Mesoscale Discussion 1713 NWS Storm Prediction Center Norman OK 0521 PM CDT Fri Jul 26 2024 Areas affected...Central and Southern Arizona Concerning...Severe potential...Watch unlikely Valid 262221Z - 262345Z Probability of Watch Issuance...20 percent SUMMARY...Some severe gusts are possible as storms move off of the higher terrain into an environment characterized by hot and dry boundary-layer profiles. Due to the isolated nature of this convection, watch issuance appears unlikely at this time. DISCUSSION...Storms that developed this afternoon on the Mogollon Rim have begun to move into southern Arizona and the lower terrain, where hot and dry boundary layer profiles will support gusty thunderstorm outflow capable of 60 MPH winds. The greatest chances for severe wind gusts will be with the most intense convective cores moving towards the eastern portions of Phoenix, where some loose organization of outflow into a bowing segment has been observed. Further southeast near Tuscon, surface observations show cooler and drier air, resulting in a relative minima of ML/MUCAPE. Any storms that move into this environment may decrease in intensity more quickly than western portions of the risk area. ..Halbert/Weinman/Hart.. 07/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1712 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN WYOMING INTO NORTHWEST NEBRASKA AND SOUTHWEST SOUTH DAKOTA
Mesoscale Discussion 1712 NWS Storm Prediction Center Norman OK 0345 PM CDT Fri Jul 26 2024 Areas affected...Eastern Wyoming into northwest Nebraska and southwest South Dakota Concerning...Severe potential...Watch unlikely Valid 262045Z - 262245Z Probability of Watch Issuance...5 percent SUMMARY...Thunderstorm coverage should continue to increase across eastern Wyoming into far northwest Nebraska and southwest South Dakota through the late afternoon. The primary hazard with this convection will be sporadic severe wind gusts. Watch issuance is not expected. DISCUSSION...Recent GOES visible imagery shows a gradual build up and deepening of cumulus along a surface cold front across portions of eastern WY, northwest NE, and southwest SD, as well as within the terrain of the Black Hills. Additionally, new convective development is noted on an expanding cold pool emanating out of northern CO/far southeast WY. This activity has largely remained sub-severe thus far, likely owing to a combination of poor deep-layer shear and meager buoyancy within a well-mixed and relatively dry environment. However, increasing ascent ahead of a subtle mid-level impulse (translating eastward across southern WY) along with rapidly diminishing MLCIN will likely result in increased thunderstorm coverage along the front and outflow boundary in the next couple of hours (a few lightning flashes have already been noted with the shallow convection over the Black Hills). Mean storm motions and deep-layer shear vectors oriented largely along the front should foster storm interactions resulting in multicell clusters later this evening. Given the deeply-mixed boundary layer in place across the region, strong to severe downburst winds appear to be the predominant hazard. 25-30 knot mid-level flow may support some organization of deeper cells or more consolidated clusters, but convective outflow will likely limit the potential for long-lived, well-organized convection. ..Moore/Gleason.. 07/26/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0341 PM CDT Fri Jul 26 2024 Valid 281200Z - 031200Z Multiple mid-level impulses will traverse the northwestern U.S. Days 3-5 (Sunday-Tuesday) before upper riding builds over the western and central CONUS through most of next week. The passing mid-level impulses will encourage dry and occasionally breezy conditions across areas east of the Cascades into the Great Basin. The best chance for Elevated equivalent meteorological surface conditions will be over southeast Nevada into Utah on Sunday, where 40 percent Critical probabilities have been introduced. These conditions may persist into Monday across the same areas, as well as the lee of the Cascades with the progression of a mid-level impulse. A stray dry thunderstorm or two may also occur ahead of this impulse across the northern Rockies somewhere in the Monday-Tuesday time frame, though coverage and available buoyancy appears too marginal for dry thunderstorm probabilities this outlook. Relatively quiescent fire weather conditions are expected through the rest of next week across the Interior West as mid-level impulses clear the region and upper ridging becomes established. ..Squitieri.. 07/26/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Post-Tropical Cyclone Bud Forecast Discussion Number 10

1 year ago
Issued at 200 PM PDT Fri Jul 26 2024 000 WTPZ42 KNHC 262036 TCDEP2 Post-Tropical Cyclone Bud Discussion Number 10 NWS National Hurricane Center Miami FL EP022024 200 PM PDT Fri Jul 26 2024 Bud has failed to produce any organized deep convection near its low-level center during the last 18 hours or so. Therefore, it no longer satisfies the criteria of a tropical cyclone, and Bud is being designated as a post-tropical cyclone with this advisory. The intensity estimate is a little uncertain because of the lack of recent scatterometer data, but subjective and objective satellite intensity estimates are around 25-32 kt. Therefore, the initial intensity is lowered to 30 kt for this advisory. Bud is being steered along the south side of a low- to mid-level subtropical ridge, and the system should move generally westward for the remainder of today. Over the weekend, the post-tropical low and its remnants should turn west-southwestward in the low-level trade wind flow. Gradual weakening is forecast as the shallow cyclone spins down over cooler waters and in a drier, more stable environment. While some intermittent bursts of convection could occur during the next couple of days, this should not stop the overall weakening trend. This is the last NHC advisory on Bud. For additional information on the post-tropical cyclone, please see the High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php FORECAST POSITIONS AND MAX WINDS INIT 26/2100Z 19.2N 120.5W 30 KT 35 MPH...POST-TROPICAL 12H 27/0600Z 19.1N 121.8W 25 KT 30 MPH...POST-TROP/REMNT LOW 24H 27/1800Z 18.9N 123.4W 25 KT 30 MPH...POST-TROP/REMNT LOW 36H 28/0600Z 18.5N 125.0W 20 KT 25 MPH...POST-TROP/REMNT LOW 48H 28/1800Z 17.8N 126.6W 20 KT 25 MPH...POST-TROP/REMNT LOW 60H 29/0600Z...DISSIPATED $$ Forecaster Kelly
