Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Sat Sep 21 2024 Valid 220100Z - 221200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHERN HIGH PLAINS... ...SUMMARY... Scattered severe storms capable of all hazards remain possible this evening across portions of the southern High Plains. ...01z Update... Strong upper low has progressed into the Four Corners region early this evening as the primary mid-level speed max translates across southern NM. Large-scale ascent is now spreading across the southern High Plains, and scattered-numerous thunderstorms have evolved across eastern NM into the TX Panhandle. In response to the trough, LLJ should increase a bit over the next few hours, and continued clustering is expected, especially across the TX South Plains into the TX Panhandle. Additionally, several supercells persist within southeast upslope flow regime across eastern NM, south of the synoptic front. 00z sounding from MAF exhibits steep lapse rates with ample shear for supercells, though weak inhibition is noted around 2km. Large hail and damaging wind threat continues with this activity, along with some risk for tornadoes with more discrete supercells. ...Elsewhere... Southern influence of northern-stream short-wave trough is aiding multiple thunderstorm clusters across the upper Midwest. Low-level warm advection is also contributing to this activity, but thermodynamic profiles are not particularly impressive with mostly modest instability noted. Some risk for wind/hail will continue, especially for the next few hours. Boundary-layer cooling should contribute to weakening buoyancy across the Middle Atlantic region. Some risk for locally strong winds persist for the next 1-2hr but overall the severe risk is gradually waning. ..Darrow.. 09/22/2024 Read more

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sat Sep 21 2024

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

Offshore of Southern Mexico:
A trough of low pressure is producing a large area of showers and
thunderstorms located a few hundred miles south of the coast of
southern Mexico. Environmental conditions appear conducive for some
slow development of this system while it meanders offshore the next
few days, and a tropical depression could form during the early or
middle part of next week when the system begins to move slowly
eastward or northeastward toward the coast of southern Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...40 percent.

Central Portion of the East Pacific:
An area of low pressure could form well to the southwest of the
southwestern coast of Mexico during the next couple of days.
Environmental conditions appear conducive for some slow development
of this system, and a tropical depression could form during the
early or middle part of next week while the system moves slowly
eastward or northeastward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0347 PM CDT Sat Sep 21 2024 Valid 231200Z - 291200Z A complicated/chaotic upper-air pattern will evolve across the United States this week. Early in the week, the upper-low across the Southwest this weekend will continue to open up and lift in/through the Plains. In its wake, an expansive ridge will take hold across the West, driving a short-wave trough southward through the Plains, by midweek. By late week, a series of short-wave troughs will move across the Pacific Northwest coincident with a closed low developing across the southern Plains. The result will be cooler/wetter pattern across southern Plains and eastern United States. Across the west, although a ridge will develop by early week, generally weak flow and unreceptive fuels will limit fire-weather concerns. Thus, large-scale critical fire-weather concerns appear to be minimal this week. ..Marsh.. 09/21/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
