SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1112 AM CST Sun Dec 25 2022 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Sporadic thunderstorms may occur over parts of northern California and southwest Oregon Monday night into Tuesday morning. Severe weather is not expected. ...Synopsis... An upper trough will move from the Plains into the Southeast on Monday, with a cold front and high pressure reinforcing the stable air mass from the Gulf of Mexico to the Atlantic Coast. To the west, the upper ridge will continue to break down over the Pacific Northwest as an intense mid/upper level jet streak noses into northern CA and OR into Tuesday morning. An associated deep surface low is forecast to approach Vancouver Island and the west coast of WA, enhancing surface convergence. QG forcing for ascent will increase Monday night across northern CA and into southwest OR as height falls occur along with low-level warm advection. Here, MUCAPE of 100-300 J/kg may develop behind the initial warm advection precipitation and as the stronger cooling aloft steepens lapse rates, most likely after 09Z. Forecast soundings reveal that some of these storms will be elevated, though SBCAPE will develop near the coast closer to 12Z. Given very strong winds just off the surface, a few strong wind gusts may occur. ..Jewell.. 12/25/2022 Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0953 AM CST Sun Dec 25 2022 Valid 251700Z - 261200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track. ..Squitieri.. 12/25/2022 .PREV DISCUSSION... /ISSUED 1149 PM CST Sat Dec 24 2022/ ...Synopsis... The surface high within the Plains will shift into the Southeast today. An upper-level shortwave trough will dig southward into the Northern Plains. A weak surface low in the southern High Plains will develop in response to the shortwave trough. Some cool, dry, down-peninsula flow will occur in Florida behind the cold front. Overall, however, continued cold temperatures and unreceptive fuels will keep fire weather concerns low. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0949 AM CST Sun Dec 25 2022 Valid 251630Z - 261200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected through tonight. ...Synopsis... The general pattern of a midlevel ridge over the Great Basin and a downstream trough over the eastern CONUS will persist through early Monday, with dry/stable conditions in the low levels. Some precipitation is expected along the Pacific Northwest coast, in advance of a shortwave trough that will approach by early Monday. Some weak buoyancy (rooted in the mid levels) will be possible within the warm advection regime preceding the midlevel trough, but the threat for thunderstorms is expected to remain negligible. ..Thompson/Lyons.. 12/25/2022 Read more

See previous discussion below. ..Bentley.. 12/24/2022 .PREV DISCUSSION... /ISSUED 1142 PM CST Fri Dec 23 2022/ ...Synopsis... High pressure will generally remain in place in the West and parts of the Plains on Sunday. The main high pressure center east of the Rockies will likely shift more into the Southeast. Some moderation of the cold temperatures in the southern Plains is also expected. Nonetheless, poor fuel receptiveness to fire and otherwise poor overlap of dry/windy conditions will continue to limit fire concerns. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0106 PM CST Sat Dec 24 2022 Valid 242000Z - 251200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Little if any thunderstorms are expected through tonight. An isolated flash cannot be ruled out over parts of Oregon. No changes were made from the previous outlook. Weak elevated MUCAPE around 100-200 J/kg may develop toward 00Z over parts of southwest Oregon with warm advection near 850 mb south of the main upper trough. However, overall coverage of thunderstorms is expected to remain below the 10% threshold. ..Jewell.. 12/24/2022 .PREV DISCUSSION... /ISSUED 1018 AM CST Sat Dec 24 2022/ ...Synopsis... A cold, continental air mass dominates the majority of the CONUS, in the wake of a deep cyclone now over western QC. A midlevel shortwave trough will crest the ridge along the Pacific coast while moving over WA later today. Very weak midlevel buoyancy will accompany the warm advection regime today near the WA/OR coast, and some shallow/post-frontal buoyancy is expected by this evening. In both cases, the threat for thunderstorms over land is too low to warrant the addition of an outlook area. Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1032 AM CST Sat Dec 24 2022 Valid 251200Z - 261200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are unlikely over the contiguous United States on Sunday. ...Synopsis... An upper low will remain over eastern Canada on Sunday with an upper ridge over the West. In between, another shortwave trough will amplify as a wave dives southeastward across the Plains and toward the MS Valley. This will maintain a relatively stable surface pattern with offshore winds over the Gulf of Mexico and East Coast due to high pressure. Over the Pacific Northwest, heights will lower as a shortwave trough approaches the coast, but the deeper temperature gradient aloft will remain well offshore through Monday morning. As such, instability is not forecast to favor thunderstorms over land. Elsewhere, lake-effect snow will likely impact parts of northern NY, and a lightning flash cannot be ruled out near Lake Ontario. However, coverage of lightning is forecast to remain below the outlook threshold of 10%. ..Jewell.. 12/24/2022 Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1115 AM CST Fri Dec 23 2022 Valid 241200Z - 251200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected over the contiguous United States on Saturday. ...Synopsis... An expansive upper-level trough will extend from eastern Canada south over much of the eastern U.S. on Saturday as upper-level ridging dominates across much of the western states. A low-amplitude shortwave trough will move onshore across the Pacific Northwest Saturday accompanied by rain showers. NAM forecast soundings depict minimal elevated instability (less than 200 J/kg) near the coast, and a sporadic lightning strike will be possible in this area as precipitation moves onshore. Overall, the risk remains too low to introduce thunder probabilities with this outlook. Elsewhere, surface high pressure and a very cold/stable air mass will preclude thunderstorm development across the CONUS on Saturday. ..Bunting.. 12/23/2022 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1022 AM CST Fri Dec 23 2022 Valid 231630Z - 241200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated lightning flashes will be possible today across parts of New England and south Florida. ...Synopsis... A deepening cyclone will develop northward across southwestern ON and western QC, within the left exit region of a 170 kt jet streak that will rotate around the eastern periphery of a deep mid-upper low over the Great Lakes. South of the cyclone, an arctic cold front will continue to surge eastward across the Mid-Atlantic/New England today, and southeastward into south FL. Buoyancy rooted in the mid levels will remain limited across New England, with only isolated lightning flashes expected with embedded/elevated convection. A narrow/forced band of showers, and very isolated lightning flashes, will move quickly offshore of NJ prior to 17z. Otherwise, the primary pre-frontal band of convection has shifted southward into the FL Straits, and only isolated thunderstorms will be possible this afternoon along the cold front/wind shift. ..Thompson/Jewell.. 12/23/2022 Read more

MD 2069 CONCERNING HEAVY SNOW FOR WESTERN NEW YORK STATE
Mesoscale Discussion 2069 NWS Storm Prediction Center Norman OK 0951 AM CST Fri Dec 23 2022 Areas affected...western New York State Concerning...Heavy snow Valid 231551Z - 232145Z SUMMARY...Heavy snow with lake-enhanced rates of 1-2+ in/hr and localized blizzard conditions possible through much of the afternoon. DISCUSSION...In the wake of a strong surface low and cold front moving across the northeastern US, snow is forecast to increase in intensity and persists across portions of western NY State through much of this afternoon. Over the last 90 min, snow has increased in intensity with below 1/4 mile visibility and heavy snow reported at several locations along the eastern shores of lake Erie. As the surface low is forecast to drift slowly northeastward, low and mid-level winds are expected to become more southwesterly with time, aligning more favorably with the lake axis. Significant lake-enhancement of ongoing snow is expected within the post-frontal arctic airmass. Rates of 1-2 in/hr with localized rates greater than 2+ in/hr are possible. In addition to the heavy snow, the strong fetch of low-level southwesterly flow will be enhanced by strong surface pressure gradients along the backside of the surface low. Numerous gusts greater than 50 mph have been noted across western NY State in the last 2 hours. Localized blizzard conditions are likely along the immediate lake shore, where heavy blowing snow and strong wind gusts to 50-60 mph will likely persist well into the afternoon. ..Lyons.. 12/23/2022 ...Please see www.spc.noaa.gov for graphic product...

The Utah Division of Wildlife Resources stocked more than 8.2 million fish in the state's waterbodies in 2022 to offset drought effects and create a positive fishing experience for the public. The department stocks fewer, larger fish, and releases them in waterbodies that were less affected by the drought. ABC4 (Salt Lake City, Utah), Dec. 13, 2022

The Feather River Fish Hatchery intends to exceed its typical production quota of 6 million fall-run Chinook salmon to support California's commercial and recreational salmon fisheries. The hatchery raised and released 8 million fall-run Chinook salmon smolts in 2022. The hatchery is aiming to produce about 8 million fall-run Chinook salmon smolts and 1.5 million fall-run Chinook salmon fingerlings in 2023, for an increase of 3.5 million over typical production goals. Ongoing drought, low adult returns and a thiamine deficiency has affected in-river production. YubaNet (Nevada City, California), Dec. 16, 2022
