Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0136 PM CST Tue Dec 02 2025 Valid 031200Z - 041200Z ...NO CRITICAL AREAS... No changes to the Day 2 Fire Weather Outlook as minimal fire weather concerns exist across the contiguous U.S. An offshore pressure gradient across southern CA amplified by a surface high moving into the Interior West should increase Wednesday night into Day 3/Thursday morning as a cold front presses through the Desert Southwest. This will result in east-northeast winds of 15-25 mph in wind-prone areas and terrain gaps coupled with relative humidity falling to 15-20% in some areas. However, fuels conducive to significant wildfire spread remain subdued, mitigating impact from the expected heightened fire weather conditions. ..Williams.. 12/02/2025 .PREV DISCUSSION... /ISSUED 0141 AM CST Tue Dec 02 2025/ ...Synopsis... On the backside of a midlevel trough moving across the Four Corners region, surface high pressure will build over the Great Basin. This will yield an enhanced offshore pressure gradient across southern CA. While locally dry/breezy conditions are expected (especially over the wind-prone mountains and valleys), marginal fuels and limited RH reductions should keep any fire-weather risk localized. ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Mesoscale Discussion 2248
NWS Storm Prediction Center Norman OK
1234 PM CST Tue Dec 02 2025
Areas affected...Southern New York into New England
Concerning...Heavy snow
Valid 021834Z - 022230Z
SUMMARY...Heavy snowfall rates between 1-2 inches per hour remain
likely across southern New York into portions of New England this
afternoon.
DISCUSSION...Latest radar mosaics show the development of a snow
band across portions of south/southeastern New York in response to
strengthening frontogenesis between the 925-850 mb levels across the
Mid-Atlantic/New England coast. Surface observations and web cams
under this band are reporting visibility reductions between 1/4 to
1/2 mile, which given weak winds across the region, are likely being
driven primarily by moderate to heavy snowfall rates. Broad-scale
ascent ahead of an approaching upper wave and more focused mesoscale
ascent within the warm advection branch of an intensifying low-level
cyclone (augmented by frontogenetical responses) will remain
favorably phased through the remainder of the afternoon over the
greater New England region. This will continue to favor widespread
light/moderate precipitation and the maintenance and/or development
of heavier precipitation bands. Consequently, snowfall rates between
1-2 inches/hour will remain likely for areas north of the surface
freezing line. Nearly isothermal temperature profiles from the
surface to around 850 mb suggests that areas near the surface
freezing line may continue to see rapid fluctuations in
precipitation type between snow, sleet, and potentially freezing
rain.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0102 PM CST Tue Dec 02 2025 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated to scattered thunderstorms are possible on Thursday across coastal portions of the western and central Gulf Coast vicinity. Severe potential appears low at this time. ...Western and Center Gulf Coast vicinity... Broad upper troughing will envelop much of the CONUS on Thursday. Strong surface high pressure will be in place over the Rockies/Great Basin, as well as across the Midwest. Meanwhile, a cold front will be draped along/just offshore the TX coast, while a warm front extends eastward near the LA coast, then southeast across the eastern Gulf. As an upper shortwave trough moves across the Plains, a weak coastal low will develop along the Upper TX Coast/LA coast late in the period. This may allow richer Gulf moisture to move into far southeast LA and coastal MS/AL in the 09-12z time period. Midlevel warm advection and increasing ascent atop a cool boundary layer will support elevated thunderstorm activity along portions of the western/central Gulf coast through the period. While some surface-based instability could move inland very late in the period, this is uncertain and may remain over immediate coastal areas of southeast LA. Overall, severe potential is expected to remain limited given Gulf moisture will mostly remain offshore through the period, though trends will be monitored for some increasing potential late in the Day 3 (early Friday morning) time frame. ..Leitman.. 12/02/2025Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK Issued by 15th OWS Scott Air Force Base IL 1115 AM CST Tue Dec 02 2025 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible over southeast Texas into Louisiana on Wednesday into early Thursday morning. Severe storms appear unlikely. ...Synopsis... A broad, low-amplitude mid-level trough will traverse the central CONUS tomorrow (Wednesday), aiding in the reinforcement of surface high pressure and associated static stability across most of the CONUS. While thunderstorm development should be suppressed over most locales, isolated thunderstorms may develop within a broad warm-air advection regime along the western Gulf Coast. Thunderstorms will be most likely as a cold front surges into the Gulf, locally enhancing low-level lift within the warm-air advection regime. Forecast soundings along the TX/LA coast and inland suggest that a stable layer will be in place, so storms inland should be elevated in nature. Given the expected meager buoyancy, the risk for severe storms appears too low for probabilities. ..15_ows.. 12/02/2025Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1028 AM CST Tue Dec 02 2025 Valid 021700Z - 031200Z ...NO CRITICAL AREAS... No changes to the Day 1 Fire Weather Outlook. Increasing westerly flow aloft south of an advancing mid-level trough along with a deepening lee surface trough along the central/southern High Plains will support a favorable environment for dry, downslope flow across east-central NM and the TX Panhandle through the afternoon. West-southwest winds of 15-20 mph combined with relative humidity as low as 15% are expected. However, the overall fuelscape remains unreceptive to significant wildfire spread although pockets of drier fuels/cured grasses could align with the dry and breezy conditions to support locally elevated fire weather concerns. ..Williams.. 12/02/2025 .PREV DISCUSSION... /ISSUED 0139 AM CST Tue Dec 02 2025/ ...Synopsis... Within the base of a gradually amplifying large-scale trough over the West, a belt of moderate midlevel westerly flow will overspread the southern Rockies and adjacent High Plains today. In response, a lee cyclone will deepen in the vicinity of northeastern NM. These factors will contribute to dry/breezy downslope flow from eastern NM into the TX Panhandle and South Plains during the afternoon. While a corridor of 20 mph sustained west-southwesterly surface winds are expected amid 15-20 percent RH, unreceptive fuels should limit most fire-weather concerns. East of the lee cyclone, dry/breezy return flow will develop across northwest TX into western OK. Similarly, marginal fuels should limit the wildfire risk. ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1022 AM CST Tue Dec 02 2025 Valid 021630Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No organized severe storms are anticipated today. ...Northeast FL... A large upper trough is spreading across the eastern states today, with a strong cold front extending across southeast GA and northern FL. Scattered showers and a occasional thunderstorms have been occurring along the front, in a moist and marginally unstable air mass. While a strong storms cannot be completely ruled out late this morning across northeast FL, the area of concern is small enough and convective trends are weak enough to suggest the risk is less than 5%. ...Outer Banks NC... A surface low has formed along the cold front sweeping eastward across eastern NC. This is aiding the creation of favorable low-level shear profiles from the Outer Banks eastward/offshore. Radar imagery suggests several rotating storms offshore, and this trend will continue. Present indications are that the risk of severe weather will also remain just east of the coast, so no probabilities have been added. ..Hart/Moore.. 12/02/2025Read more
