Valid 291200Z - 301200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER WESTERN AND CENTRAL MONTANA...AND PARTS OF THE CENTRAL HIGH PLAINS AND SOUTHERN PLAINS...
...SUMMARY... A few storms may produce marginal hail or strong gusts from eastern New Mexico and western Texas across Oklahoma and toward northern Louisiana on Friday. A few strong to severe storms may also occur across western Montana with gusty winds and marginal hail. Isolated damaging wind gusts are also possible across portions of the central High Plains.
...MT... An upper low will weaken as it moves from the Great Basin to the central Rockies, with cool temperatures aloft persisting over much of the region. A surface trough will deepen over central MT with a cold front moving across ID and into western MT. Daytime heating and steepening lapse rates may aid wind gust potential as storms develop late in the day from western into central MT. Relatively strong upper-level winds will elongate hodographs, and may support cells producing marginal hail.
...Central High Plains... Low-level moisture will spread westward into northern CO and eastern WY as a low pressure trough develops from MT into eastern CO during the afternoon. Steep lapse rates and 50s F dewpoints will result in perhaps 1000 J/kg MUCAPE supporting storms forming from southeast WY into the Front Range. These storms may produce strong to locally severe outflow winds.
...Southern Plains... An upper-level jet of 50-70 kt will move into southern NM and western TX, though midlevel winds will be at or below 30 kt. Strong heating will occur over the region while southeast surface winds maintain moisture influx. Storms should form during the afternoon from eastern NM and spread across western TX and perhaps into southwest KS. Cool midlevel temperatures may support marginal hail, though gusty outflow winds will be the most common threat. Additionally, a few storms may occur farther east from OK into northeast TX, AR and LA where dewpoints and instability will be greater. Any storms that can form within the uncapped air mass would likely move southeastward with isolated strong gust potential.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE PACIFIC NORTHWEST...
...SUMMARY... Thunderstorms with severe wind gusts, large hail and an isolated tornado threat are expected across parts of the Pacific Northwest this afternoon and evening.
...Pacific Northwest... An upper-level low will remain over central California today. On the northern periphery of the system, bands of large-scale ascent will move westward across the Pacific Northwest, providing support for thunderstorm development. At the surface, a low will deepen and move northwestward from eastern Oregon into southern Washington. A surface trough will extend southward from the low into north-central and west-central Oregon. Thunderstorms are forecast to first develop across southern Oregon around midday, with convective coverage gradually increasing over much of Oregon during the afternoon. A larger-scale line segment is expected to organize and move northwestward across Oregon late this afternoon and into southern Washington early this evening.
As surface temperatures warm today, instability will increase along the surface trough with MLCAPE expected to peak in the 1200 to 1500 J/kg range. The instability combined with 30 to 40 knots of mid-level east-southeasterly flow, along with low to mid-level lapse rates in the 8 to 8.5 C/km range, will support severe thunderstorm development. This environment will be favorable for severe wind gusts and isolated large hail within the stronger parts of an extensive line segment. Near the surface trough, 0-3 km storm-relative helicity is forecast to increase into the 200 to 250 m2/s2 range by late afternoon, which could also support an isolated tornado threat. Any tornado threat would mainly be associated with rotating elements embedded in the line. As the line moves north-northwestward and expands, a severe threat is expected to move into southern Washington by early evening. A marginal severe threat could impact parts of central and northern Washington later in the evening.
...East-central Colorado... A mid-level trough will move northward across the central Plains today. At the surface, upslope east-southeasterly flow will be in place across eastern Colorado. Along the Front Range, the Denver Cyclone is expected to develop by afternoon. Topographic lift and increasing low-level convergence will result in scattered thunderstorm development from the Palmer Divide northward into north-central Colorado. Forecast soundings along this corridor by late afternoon have 0-6 km shear in the 20 to 30 knot range with 700-500 mb lapse rates around 8 C/km. This should support a hail threat with the stronger cells.

SPC Day 2 Fire Weather OutlookSPC Day 2 Fire Weather Outlook  Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1248 AM CDT Thu May 28 2026
Valid 291200Z - 301200Z
...Synopsis... An upper-level low over the Great Basin will translate into an open wave as persistent ridging continues across the central CONUS. A compact upper low will move out of southern Quebec into New England on Friday night, transporting ample moisture and a southward progressing cold front. Fire weather concerns are expected to remain limited to the eastern Great Basin and Southwest as the upper-level trough advances northward.
...Great Basin and Southwest... Dry, southerly flow is expected to continue into Day 2/Friday as upper level troughing lifts over the region. At peak heating, RH reductions to 15-20% and south-southwesterly winds of 15-25 mph are expected to promote Elevated fire weather conditions across the eastern Great Basin, Colorado Plateau, and portions of the Southwest. A 50-60 kt mid-level jet will emerge at the base of the lifting trough, supporting a narrow region of locally critical fire weather conditions in terrain-favored areas of the Four Corners where wind gusts of up to 35 mph and less than 15% RH may coalesce.

SPC Day 1 Fire Weather OutlookSPC Day 1 Fire Weather Outlook  Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1247 AM CDT Thu May 28 2026
Valid 281200Z - 291200Z
...Synopsis... A high amplitude blocking pattern will continue as an upper low remains centered over the western CONUS with downstream ridging across the northern High Plains/Upper Midwest. The main trough axis will gradually lift into the central Plains while moisture advection occurs ahead of the upper low, encouraging additional chances for precipitation across the central CONUS. As upper troughing pushes down the Eastern Seaboard, a cold front is expected to progress southward through the Mid-Atlantic, bringing below-normal temperatures and more opportunities for spotty precipitation.
...Great Basin and Southwest... An upper-level low anchored over the Sierra Nevada and corresponding surface low over western ID will bolster dry and breezy southerly flow across portions of the Great Basin and Southwest this afternoon. South winds of 15-25 mph, RH values of 15-20% (as low as 10% in valleys), and dry/cured fuels in lower elevations will support Elevated to locally critical fire weather concerns across portions of AZ and far western NM into the eastern Great Basin and CO Western Slope.
...Northeastern Montana... Surface troughing extending across the northern High Plains into the Northern Rockies and surface high pressure over the Great Lakes region will reinforce dry southeasterly flow atop recently receptive fuels in northeastern MT. Elevated fire weather conditions are expected as daytime relative humidity declines to around 20% and southeasterly sustained winds increase to 15-25 mph.
