SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1212 AM CST Sun Dec 01 2024 Valid 021200Z - 031200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough is expected to be situated over the eastern portions of the CONUS through the day on Monday, though some shortening of the wavelength should allow for some eastward progression through the day. At the surface, a broad area of high pressure is expected to translate southward across the central Plains, reinforcing the cool surface conditions and bringing generally light winds. As such, no significant fire concerns are expected across much of the CONUS on Monday. The exception may be western parts of the Florida peninsula, which may be in an unmodified dry continental air mass, resulting in low RH. Along with modestly dry fuels, this may create localized conditions favorable for fire spread. However, winds currently appear to be too light to introduce Elevated highlights on this outlook. ..Supinie.. 12/01/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1212 AM CST Sun Dec 01 2024 Valid 011200Z - 021200Z ...NO CRITICAL AREAS... ...Synopsis... A broad mid-level trough will remain in place over the eastern half of the CONUS through the day on Sunday, with northwesterly mid-level flow resulting in expansive surface high pressure across much of the CONUS. With the cool surface conditions and light winds, fire concerns are largely expected to be minimal. The exception may be portions of the western Florida peninsula, where unmodified dry continental air may be present, resulting in low RH for the area along with modestly dry fuels. However, confidence in breezy conditions in the area is currently poor, so no highlights will be introduced at this time. ..Supinie.. 12/01/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 2247 CONCERNING HEAVY SNOW FOR PORTIONS OF NEW YORK DIRECTLY DOWNSTREAM OF LAKE ONTARIO
Mesoscale Discussion 2247 NWS Storm Prediction Center Norman OK 0803 PM CST Sat Nov 30 2024 Areas affected...portions of New York directly downstream of Lake Ontario Concerning...Heavy snow Valid 010203Z - 010600Z SUMMARY...Heavy snow -- falling at rates of up to 2" per hour -- will continue eat of Lake Ontario, with a slight northward shift in the main snow band expected over the next couple of hours. DISCUSSION...Latest radar data shows heavy snow continuing across portions of upstate New York east of Lake Ontario. The heaviest snow has been occurring near and south Watertown, and eastward into the Tug Hill area. However, recent trends indicate that the main band is shifting/reforming slightly to the north. This is likely occurring in response to very slight backing of the 0 to 3km flow -- as depicted over the past few hours per the Fort Drum (KTYX) WSR-88d. As such, it appears that the area of heaviest snowfall may gradually become focused near and north of Watertown (and areas eastward) over the next few hours. ..Goss.. 12/01/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1101 PM CST Sat Nov 30 2024 Valid 021200Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms will be possible on Monday across south Texas. Severe storms are not expected. ...Synopsis... A dry, continental polar air mass will be in place across the CONUS on Monday. The only exception is across far south Texas. Easterly flow will strengthen across the Gulf on Sunday night and Monday as a strong anticyclone moves into the central CONUS. This will cause mid to upper 60s dewpoints to advect inland across far south Texas. Meager instability may develop which could result in a few isolated thunderstorms. However, this is more likely offshore where somewhat greater instability is likely. ..Bentley.. 12/01/2024 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1054 PM CST Sat Nov 30 2024 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected through tonight. ...Synopsis... A large-scale trough/cyclonic flow over the northeast CONUS will maintain a relatively cool pattern east of the Rockies with little threat for deep convection. Shallow convection will persist in lake effect bands (especially Lake Erie and Lake Ontario), but slowly veering/weakening flow with time and marginal buoyancy should lead to weakening of the bands by this evening/tonight. Farther southwest, a modifying air mass will contribute to destabilization and the potential for isolated thunderstorms in a warm advection zone along a coastal front near the lower TX coast. However, the richer low-level moisture will likely remain offshore, and the potential for thunderstorms inland should remain too low to warrant an outlook area. ..Thompson/Supinie.. 12/01/2024 Read more
