SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0116 AM CDT Sun Mar 17 2024 Valid 181200Z - 191200Z ...NO CRITICAL AREAS... ...Synopsis... Through the day on Monday, the mid-level pattern is expected to be a longwave trough across the eastern US with a decaying cutoff low over the southwest US. This is expected to result in northwesterly flow across the central US. Perhaps some locally Elevated fire weather conditions are possible across parts of Kansas and Oklahoma, but fuels do not appear particularly receptive across much of this area. Therefore, no risk areas are outlined at this time. ..Supinie.. 03/17/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0115 AM CDT Sun Mar 17 2024 Valid 171200Z - 181200Z ...NO CRITICAL AREAS... ...Synopsis... During the day on Sunday, mid-level pattern will be characterized by a digging longwave trough over the central and eastern US with a cutoff low in the southwest US. This will promote cool, northerly surface flow across much of the central US and precipitation across parts of the southern High Plains. As such, aside from perhaps some locally Elevated fire risk in parts of southwest Kansas and northwest Oklahoma, fire concerns are expected to be minimal. ..Supinie.. 03/17/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1149 PM CDT Sat Mar 16 2024 Valid 181200Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS EARLY MONDAY ACROSS PARTS OF THE NORTHERN AND WEST CENTRAL FLORIDA PENINSULA... ...SUMMARY... Strong thunderstorms may move inland off the Gulf of Mexico into portions of the northern and central Florida peninsula early Monday, perhaps accompanied by some risk of severe weather. ...Synopsis... Split flow emanating from the western mid-latitude Pacific likely will remain amplified through this period, with a new high beginning to form within building ridging, near or southwest of the Gulf of Alaska. Downstream, models still indicate that the initially prominent high over Pacific Northwest vicinity will gradually become more suppressed, but blocking will be maintained, with the persistent low over the Southwest remaining quasi-stationary or perhaps retrograding a bit to the west of the lower Colorado Valley. To the east of this regime, a vigorous short wave trough is forecast to continue digging southeast of the lower Missouri Valley, through the south Atlantic coast vicinity, before turning eastward and offshore by late Monday night. As this occurs, larger-scale mid/upper troughing centered near the Atlantic Seaboard may assume a neutral tilt, with increasingly divergent downstream flow perhaps supporting strengthening surface cyclogenesis well offshore over the western Atlantic. Initial frontal wave development may commence closer to the coast by early Monday, with a significant trailing cold front advancing southeastward in its wake, through much of the northern Gulf Basin and Florida by 12Z Tuesday. ...Florida... In advance of the cold front, models still indicate that low-level flow will veer to an increasingly westerly component while continuing to strengthen (up to 30-40+ kt around 850 mb) during the day across northern into central portions of the peninsula. It appears unlikely that the Atlantic sea-breeze will be maintained near coastal areas through peak afternoon destabilization, except perhaps across southeastern Florida, where forecast soundings (particularly the NAM) suggest that warm layers in mid-levels will contribute to strong inhibition. Due to spread concerning shorter wavelength developments within the large-scale flow, depictions of potential convective evolution into and through this period remain varied. However, while the potential for vigorous thunderstorms to develop, or be maintained, across interior and eastern portions of the peninsula appears low, it might not be out of the question that an organized cluster could spread off the northeastern Gulf into northern and west central portions of the peninsula early in the period, accompanied by some risk for damaging wind gusts before weakening. ..Kerr.. 03/17/2024 Read more
