SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0344 PM CST Mon Dec 30 2024 Valid 011200Z - 071200Z An upper-level ridge will build over the West late Day 3/Wednesday into Day 5/Friday while an upper-level trough deepens over the eastern US. An upper-level trough is forecast to move over the West late Day 5/Friday and Day 6/Saturday then over the southern and central Plains on Day 7/Sunday into Day 8/Monday. Dry conditions will persist for much of the southwest US and southern/central High Plains through the outlook period. ...Day 3/Wednesday - Day 4/Thursday: Southern California... A relatively isolated weak to moderate Santa Ana wind event will continue across of the Transverse Ranges into Day 4/Thursday evening. Locally critical winds/RH remain likely in the mountains and adjacent foothills of Ventura and western Los Angeles Counties, mostly on southern/ocean facing slopes. 40% probabilities have been maintained, but a Day 1/2 Critical area cannot be ruled out in future outlooks. Another Santa Ana wind event is possible starting on Day 7/Sunday and lasting through early next week. Forecast uncertainty precludes adding probabilities at this time, but if model trends hold, probabilities will be necessary in future outlooks. ...Day 6/Saturday - Day 7/Sunday: Southwest and southern High Plains... The trough forecast to move over the West on Day 5/Friday - Day 6/Saturday will likely lead to elevated/locally critical fire weather conditions across portions of the Southwest and southern High Plains on Day 6/Saturday - Day 7/Sunday. The timing and track of the upper-level trough are still somewhat uncertain, but the last few model runs seem to be coalescing around a solution. Future outlooks will likely introduce probabilities for critical fire weather this weekend across portions of the Southwest and southern High Plains. ..Nauslar.. 12/30/2024 ...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 0141 PM CST Mon Dec 30 2024 Valid 302000Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...20z Update... The previous forecast remains on track with no changes required. Latest guidance continues to suggest that a swath of weak thunderstorms will overspread the OH River Valley late tonight into early Tuesday morning. Some solutions, notably recent runs of the HRRR and RAP, hint that a corridor of surface-based convection may develop from northwest KY/southern IN into north-central KY/southwest OH between 07-12 UTC along the primary surface trough. SBCAPE/lifted indices will remain fairly limited (250-500 J/kg and -1 to -2 C respectively) and modulate overall convective intensity; however, 40 knot, nearly uni-directional flow within the 0-1 km layer may promote sporadic damaging wind gusts during the pre-dawn hours. Consideration was given for 5% wind probabilities, but the overall convective signal in recent guidance remains too limited to garner sufficient confidence in this potential threat. ..Moore.. 12/30/2024 .PREV DISCUSSION... /ISSUED 1022 AM CST Mon Dec 30 2024/ ...OH Valley tonight... An 80-100 knot mid-level jet max will move quickly eastward across the central Plains today, and into the mid MS Valley tonight. Strong cyclogenesis will occur in advance of this system over MO/IL, with the primary baroclinic zone sweeping across AR into KY/TN. Strengthening southerly low-level winds in the warm sector of the deepening low will result in broad low-level warm/moist advection, and perhaps just enough CAPE for a few thunderstorms late tonight across the lower and middle OH Valley. Forecast soundings show impressive low-level shear profiles, but thermodynamics are quite weak with surface-based convection unlikely. Thus the severe threat is low. Read more
