Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1058 AM CST Wed Dec 17 2025

Valid 171700Z - 181200Z

The previous forecast remains on track with only minor expansions
made across southeast CO/southwest KS to reflect latest high-res
guidance. 16 UTC surface observations show winds beginning to
increase along the northern CO Front Range, but the strongest winds
are expected later this afternoon (mainly between 20-00 UTC) as the
mid-level jet begins to impinge on the northern Rockies. It remains
unclear exactly how severe RH reductions will be in the lee of the
immediate front range where peak winds are expected. While some
guidance shows RH minimums near 20%, morning solutions don't appear
to be accurately capturing recent satellite trends with more
widespread cloud cover noted in GOES imagery than depicted in recent
HRRR/RRFS runs. This continues to limit confidence in the potential
for widespread critical fire weather conditions, though localized
critical conditions may emerge if sufficient clearing can occur.
Regardless, the strong winds coupled with slowly increasing ERC
values (near the 70th percentile) should still support a wind-driven
fire weather risk. See the previous discussion below for additional
details.

..Moore.. 12/17/2025

.PREV DISCUSSION... /ISSUED 1150 PM CST Tue Dec 16 2025/

...Synopsis...
A potent upper trough will move through the Northwest and reach the
Plains by Thursday morning. At the surface, a cyclone will deepen in
the northern Plains with a trough extending into the
central/southern Plains.

...Central/southern High Plains...
Strong mid-level winds will be nearly perpendicular to the Rockies.
This, coupled with a strong cross-Divide pressure gradient, will
foster strong sustained winds and stronger gusts in the immediate
lee of the terrain. Sustained 20-30 mph winds will be probable in
the terrain-favored areas. A period of wind gusts to 60-70 mph are
expected in the lower foothills. Farther east and south, 15-20 mph
will become more common. RH will be above elevated criteria in many
places, but 15-25% will be possible from Wyoming into Colorado.
Farther south, RH will more likely be around 15-20%. With fuels
having continued to dry, the strong surface winds will still lead to
elevated to locally critical fire weather.

...Piedmont...
Dry and modestly breezy conditions appear possible within the region
during the afternoon. RH could fall as low as 20-25%, but there is
variability within guidance. Winds will generally be light at around
10 mph. Locally elevated conditions are possible, but the
duration/spatial extent is too limited and uncertain for highlights.

SPC 1630Z Day 1 Outlook

Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1022 AM CST Wed Dec 17 2025

Valid 171630Z - 181200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTHERN IDAHO AND NORTHERN UTAH...

...SUMMARY...
While strong to locally severe winds may occur with low-topped
convection through early afternoon across parts of southern Idaho
and northern Utah, the overall threat for organized severe
thunderstorms appears low.

...Interior Northwest and Northern Great Basin/Rockies...
A powerful mid-level shortwave trough and associated sub-980 mb
surface low will move quickly eastward today across the interior
Northwest/northern Rockies and adjacent western Canada. A strong
surface cold front will likewise translate east-southeastward over
the northern Intermountain/Great Basin region late this morning into
the afternoon. Widespread cloud cover remains prevalent ahead of the
front across southern ID into northern UT and vicinity, with cool
surface temperatures and very limited low-level moisture also
present. MUCAPE is expected to remain only barely sufficient to
support convection. But, given the enhanced flow at low levels noted
on recent VWPs from KCBX/KSFX, it is not entirely out of the
question that convectively augmented gusts may exceed the already
strong background gradient winds on a localized basis. The Marginal
Risk has therefore been maintained for parts of southern ID/northern
UT and vicinity, even though the overall threat for organized severe
thunderstorms will remain low.

Valid 171300Z - 181200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE NORTHWEST AND NORTHERN INTERMOUNTAIN REGION...

...SUMMARY...
Sporadic severe wind gusts may accompany low-topped convection
across parts of the Northwest and northern Intermountain region this
morning into midday.

...Northwest/Northern Intermountain region...
A progressive/vigorous shortwave trough will continue to modestly
amplify and otherwise race east-southeastward from the
Washington/British Columbia border vicinity this morning to the
northern Plains tonight. Intense deep-tropospheric flow (highlighted
by 55-85 kt at 700 mb) will accompany this wave, yielding widespread
high winds across much of the Northwest to the northern Great
Plains.

Low-topped convection, occasionally capable of lightning and
semi-organized line segments, will continue in association with the
east/southeastward-advancing cold front, with convection potentially
expanding by late morning towards the Snake River Plain/Yellowstone
vicinity and potentially other parts of the northeast Great Basin by
afternoon. Surface-based instability will be very limited, but some
convectively enhanced wind gusts may occur.

Small earthquake of magnitude 3.0 just reported 72 km southwest of La Ciotat, France

A magnitude 3.0 earthquake near La Ciotat, Bouches-du-Rhône, Provence-Alpes-Cote d'Azur, France, was reported only 9 minutes ago by France's Réseau National de Surveillance Sismique (RéNaSS), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a very shallow depth of 5. km beneath the epicenter early evening on Tuesday, December 16th, 2025, at 6:03 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 2.7 earthquake.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In La Ciotat (pop. 33,100, 72 km away), the quake was probably not felt.

Small magnitude 3.8 earthquake 26 miles southwest of Kalifornsky, Alaska, United States

A magnitude 3.8 earthquake near Kalifornsky, Kenai Peninsula, Alaska, USA, was reported only 4 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at an intermediate depth of 50 miles beneath the epicenter early morning on Tuesday, December 16th, 2025, at 2:43 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 3.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.8.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Ninilchik (pop. 880, 11 miles away), Cohoe (pop. 1,400, 24 miles away), Kalifornsky (pop. 7,900, 26 miles away), Anchor Point (pop. 1,900, 27 miles away), Kenai (pop. 7,700, 34 miles away), Soldotna (pop. 4,500, 35 miles away), Homer (pop. 5,500, 38 miles away), and Nikiski (pop. 4,500, 41 miles away), the quake was probably not felt.
