Emigrant Fire Story The Emigrant fire started as tractor-trailer fire on the northbound Vista Del Lago exit on Interstate 5 near Pyramid Lake. The first report into the Angeles National Forest was at 1:34 p.m. on September 17, 2021. The first firefighters on-scene reported that the fire had quickly spread to the vegetation adjacent to the interstate highway and ran up the slope. With the hot, dry weather and wind, the fire quickly spread in a northerly direction, burning uphill in steep terrain with gullies and drop-offs. The US Forest Service along with Los Angeles County Fire Department sent considerable ground and aerial firefighters to the scene and battled the fire. Initially a total of twelve aircraft responded to the fire, including retardant dropping airtankers, super scoopers and helicopters providing much needed assistance to ground based firefighters. On the ground, fire engines, hand crews, fire dozers and water tenders attacked the flanks of the fire, eventually...

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE OHIO VALLEY AND PA...
...SUMMARY...
Isolated severe thunderstorms may generate hail across portions of
the Ohio Valley and Pennsylvania late tonight.
...Synopsis...
In mid/upper levels, a progressive and highly amplified northern
stream will persist, with troughs crossing the northwestern CONUS/
southwestern Canada region and southeastern Canada/northeastern U.S.
mainland. A shortwave trough -- evident in moisture-channel imagery
over parts of southwestern MN, western IA and eastern NE, is
forecast to move through the broader cyclonic-flow field toward the
eastern trough. By 12Z tomorrow, the shortwave trough should reach
parts of PA, WV and OH.
Farther west, synoptic-scale ridging will shift eastward out of the
central Rockies and northern High Plains, reaching the lower/mid
Missouri Valley and MB by the end of the period. A strong upstream
trough -- now positioned over the Pacific south of a cyclone now
west of Vancouver Island -- will move inland across northern
CA/OR/WA between 00-06Z. This trough should reach the northern
Great Basin and ID by 12Z. As associated height falls spread
eastward toward the northern/central Rockies, a cut-off low now over
western NM near the AZ border will move slowly northeastward. Its
cyclonic-flow field will spread across the CO/NM Rockies and
central/southern High Plains. A convectively augmented shortwave
perturbation -- apparent over the TX Trans-Pecos/Big Bend region --
may pivot northward then northwestward around the broader gyre today
into this evening, and become the primary 500-mb low overnight over
the San Juans near the CO/NM line.
At the surface, 11Z analysis showed a cold front from western QC
across Lake Huron, southern WI, and southern NE. This front should
reach Lake Ontario, southern Lower MI, and southern IA by 00Z,
becoming quasistationary westward across the southern NE/
northeastern CO region. By 12Z, the front should reach central New
England, northwestern PA and central IL. Substantial surface
moisture (dew points mid 60s and upward) remains confined to the
Gulf, southern FL and southern AZ.
...OH Valley/PA overnight...
Isolated to scattered, elevated thunderstorms are expected tonight
-- primarily after 06Z and ahead of the surface cold front.
Marginally sever hail is possible from the most intense cores
relatively early in the local convective cycle, with relatively
discrete cells, before modes become more clustered/messy.
Large-scale ascent -- both as warm advection and DCVA preceding the
shortwave trough -- will contribute to steepening mid/upper-level
lapse rates across this area. Low-level moisture advection and
transport above the boundary layer will increase buoyancy and reduce
MUCINH, as increasingly buoyant parcels lift to an LFC with time.
Forecast soundings suggest around 800-1200 J/kg MUCAPE, a
substantial fraction of which will be in hail-growth zones in
mid/upper levels. However, usable vertical shear will be modest
with nearly unidirectional flow through the cloud-bearing or
effective layer. Forecast soundings indicate 25-35 kt effective-
shear magnitudes, which will be somewhat greater with westward
extent. However, convective coverage may be larger and more certain
eastward, contributing to uncertainty on severe potential.
...Southwest TX...
Widely scattered to scattered thunderstorms are possible this
afternoon into early evening from the Permian Basin to near the
lowest Pecos River, in a zone of weak but sufficient low-level
convergence. Lift will be aided (and MLCINH minimized) by diabatic
heating in the area behind the ejecting Trans-Pecos trough, whose
backside DCVA field should be well north of the area by mid/late
afternoon. A well-mixed boundary layer may support strong gusts or
small hail. However, weak low/middle-level flow, and related lack
of shear (effective-shear magnitudes 20-30 kt) indicate poor
organization. At this time any severe potential appears too
uncertain and conditional for a categorical outlook.
