SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0219 AM CST Fri Dec 06 2024 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible from southeast Texas into the Lower Mississippi Valley and Mid-South on Sunday. The probability for severe thunderstorms is very low. ...Synopsis... Upper low expected to be over the TX Panhandle early Sunday is forecast to devolve into an open wave as it progresses northeastward across OK and the Ozarks into the Mid MS Valley. Enhanced mid-level southwesterly flow will accompany this system, spreading from the Mid/Lower MS Valley and into the TN Valley and Southeast as the wave moves northeastward. Strengthening low to mid-level flow is anticipated ahead of this system as well. Overall progression of this system will displace it north of the more favorable low-level moisture, which will be confined to the upper TX Coast early Sunday before advecting northeastward into more of the Lower MS Valley/Mid-South throughout the day. Warm-air advection across this moistening warm sector and modest buoyancy may result in elevated thunderstorms embedded within the larger precipitation shield. Deep-layer vertical shear will be strong but the limited buoyancy should keep the overall severe potential low. ..Mosier.. 12/06/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0138 AM CST Fri Dec 06 2024 Valid 071200Z - 081200Z ...NO CRITICAL AREAS... ...Synopsis... Limited fire weather concerns are expected for Saturday across the country, though localized concerns are possible within the higher terrain of the southern CA coast. The persistent offshore flow regime over southern CA is expected to slowly abate through the day Saturday as the upper trough currently over southern AZ ejects into the southern Plains, resulting in weakening low to mid-level flow across the region. Areas of elevated fire weather conditions (featuring 15-25 mph winds and 15-20% RH) will likely be ongoing at the start of the period within the higher terrain, but should become more isolated after 18 UTC. While similar wind/RH conditions are possible early Saturday compared to today (Friday), latest high-res guidance suggests the overall coverage of such conditions should be more limited, which precludes highlights at this time, though trends will continue to be monitored. ..Moore.. 12/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0111 AM CST Fri Dec 06 2024 Valid 061200Z - 071200Z ...Synopsis... Localized elevated fire weather conditions are expected for portions of the southern CA coast through the day and into the overnight hours. 06 UTC surface observations show a seasonally strong surface high over the northern Great Basin (MSLP values between the 75th to 90th percentile for early December). This feature, combined with a weak trough axis along the CA coast, has maintained a persistent DAG-LAX pressure gradient between -5 to -8 mb over the past 24 hours. Offshore winds are forecast to increase through 18 UTC as the pressure gradient gradually strengthens before slowly abating through the remainder of the forecast period. A shallow marine layer evident in the 00 UTC VBG sounding and coastal surface obs is expected to mix out as winds strengthen, but the warmest/driest conditions will likely reside within the thermal layer above 1700 ft (also evident in the VBG sounding and surface obs). Latest high-res guidance suggests the offshore pressure gradient will approach critical thresholds by around 16-18 UTC and may support gusts within the higher terrain between 20-30 mph as RH values fall into the teens. As such, pockets of elevated to critical fire weather conditions are possible through much of the southern CA coastal terrain - though appear most persistent/widespread between the San Gabriel and San Rafael Mountains where terrain influences will locally augment the gradient winds. Elevated fire weather conditions should become increasingly isolated through late afternoon, but may persist for some locations through early Saturday morning. ..Moore.. 12/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1234 AM CST Fri Dec 06 2024 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms are likely across a large portion of Texas on Saturday. No severe thunderstorms are expected. ...Synopsis... A southern-stream upper low is forecast to begin the period over the AZ/NM/Mexico border intersection vicinity before progressing northeastward through the southern High Plains throughout the period. Enhanced mid-level flow will accompany this low, spreading eastward across the southern Plains. Low-level flow across the southern Plains will also increase ahead of this system, resulting in strengthening warm-air advection throughout the day. Surface easterlies are expected across the Gulf of Mexico, but a stationary boundary along the TX Coast will prevent inland penetration of any notable low-level moisture. Even so, moderate mid-level moisture and increasing large-scale lift ahead of the approaching upper low will result in a large area of precipitation. Cooling mid-level temperatures may help support modest buoyancy, with isolated thunderstorms expected within the larger precipitation shield. The probability of any severe thunderstorms is very low. ..Mosier.. 12/06/2024 Read more
